Chapter 2 Problem Solutions
2.1 Define the following terms: measurement variable, control variable, dependent variable,
valve position, operational objective, control objective, controller, setpoint, measurement
error, controller output, manual mode, high-high level alarm, low-low level alarm, air fail
open, and air fail closed.
• Measurement Variable: The subset of the dependent variables affected by
changes to the process that are used to determine the effect of a change to the
process by a related independent (control) variable. For feedback control loops
measurement variables are also used to evaluate the effectiveness of changes in
the control variable. Examples: flow rate, pressure, temperature, level, motor
speed, and material properties such as chemical composition.
• Control Variable: An independent variable which is used in a process control
loop to keep a portion of the process at its desired condition. The main control
variables are: control valves, motor speed, electrical supply interruption time, and
electrical current resistance.
• Dependent Variable: These are variables affected by changes to the process
made by a related independent variable. They are used to determine the condition
of the process. When used in a feedback control loop, they are measurement
variables. When used in a feedforward control loop, they are measurement
variables related to disturbance variables. When used in the slave feedback
control loop of a cascade control scheme, they are related variables. Examples:
flow rate, pressure, temperature, level, and material properties such as chemical
composition.
• Valve Position: The valve opening area. This is used to adjust the rate of flow
through and the pressure drop incurred by a process fluid in a control valve in
order to achieve the process or operational objectives of a unit operation. Valve
position is typically measured on a scale from 0 to 100%.
• Operational Objective: A functional goal of a unit operation. It defines the unit
operation’s purpose. Tasks are designed to accomplish the operational objectives.
• Control Objective: A goal of the plant automation system. It defines the purpose
for the controls applied to a given unit operation.
Chapter 2 Page 2
• Controller: The portion of the control system that determines how the related
control variable shall be adjusted to meet the control objectives of the control
loop. A typical controller compares the measurement variable to a setpoint to
generate an error. The error is used by the controller in a control algorithm to
determine an output for the control variable.
• Setpoint: The desired value of the measurement variable. It is specified by an
operator or by another part of the plant automation system.
• Measurement Error: The difference between the measured value of the
measurement variable and the setpoint, as calculated by the controller.
• Controller Output: The change to the control variable requested by the
controller in response to the measurement error.
• Manual Mode: When an operator overrides the controller output, in order to
impose their own output for the control variable.
• High-High Level Alarm: An additional piece of safety equipment, which
activates once the level of a unit operation has exceeded the high value set for the
control system. These alarms are activated if an operator does not respond to the
high level alarm or if there is an issue with the primary level measurement device.
• Low-Low Level Alarm: An additional piece of safety equipment, which activates
once the level of a unit operation has fallen below the low value set for the control
system. These alarms are activated if an operator does not respond to the low
level alarm or if there is an issue with the primary level measurement device.
• Air Fail Open: When removing or blocking the pneumatic air from a control
valve, the valve will open to its maximum. This is a forward acting valve.
• Air Fail Closed: When removing or blocking the pneumatic air from a control
valve, the valve will close completely. This is a reverse acting valve.
2.2 Describe each of the types of independent variables that are typically available for use in
process control.
• Control valve: Operates by changing the size of the opening of a choke point in a
pipe which changes the quantity of fluid that can flow through the pipe for a given
pressure drop. Conversely, the pressure drop incurred to force a given quantity of
fluid through an opening can be adjusted.
• Electrical supply interruption time: This independent variable works to open
and close a contact on the electrical supply so that the equipment receives electric
current for only a fraction of the time. For example, by varying the fraction of
time a heater is energized, the energy input to the heater can be adjusted, which
adjusts the surface temperature of the heating element
• Electrical current resistance: A rheostat is used to vary the resistance to current
flow in an electrical circuit. This in turn varies the electrical power available to
power a motor or provide frictional heating to a heater element. For example, the
Chapter 2 Page 3
flow of fluids can be controlled by varying the momentum introduced into the
fluid by a pump or compressor. The momentum is varied by varying the electrical
current supplied to the motor that drives the device which, in turn, varies the
speed (rotation, piston travel speed, etc.) of the pump or compressor. The same
concept applies to solids by changing the speed of conveyors or extruders.
• Block valve open/close status: A block valve can be opened or closed on a fluid
contained in a pipe. In this case, the quantity of fluid moving from one unit
operation to another has only two states: full flow or no flow. This strategy is
often employed for batch unit operations.
2.3 Describe a coupled control system and why such systems should be avoided whenever
possible.
• A coupled control system is one in which an independent variable has a direct and
immediate effect on a dependent variable which is not part of its own control
loop. When this happens, the control system is less stable, less responsive, and
less capable of handling disturbances to the system, all which lead to a system
which is more difficult to control. An example of this is trying to control liquid
level in a drum by changing the pressure of the overhead gas stream, instead of
changing the flow of the liquid bottoms.

determine the number of independent variables, c) determine the number of control
variables, and d) design simple feedback control loops for each control variable.

2.8 Another example of the use of a feedback trim cascade control loop is in the operation of
a Claus sulfur process. In this process, a feed gas containing H2S is partially combusted
with air to yield a mixture of H2S, SO2, and S via the reactions:
2H2S + O2 ➔ 2H2O + 2S (2.2)
2H2S + 3O2 ➔ 2SO2 + 2H2O (2.3)
The flue gas is cooled to condense out the sulfur. It is then sent through a series of
reheaters, catalytic reactors, and condensers to produce additional sulfur via the reaction:
2H2S + SO2 ➔ 2H2O + 3S (2.4)
The key to maximizing sulfur recovery is to have the correct H2S to oxygen ratio in the
initial thermal oxidizer. Theoretically, this is a simple 2:1 ratio. However, due to
variations in the concentration and flow rate of H2S in the process gas stream plus
variations in the reaction efficiency of the thermal oxidizer and the three catalyst beds,
the true optimum can only be found experimentally. As a result, the composition of
either H2S or SO2 is measured in the final stream and this measurement is used in a
feedback trim cascade controller to the inlet air ratio controller.
Duplicate the drawing shown in Figure 2.28 and add a ratio with feedback trim control
scheme to meet the operational objectives described above.
• See Drawing 2.8-A-001/1
2.9 Consider the control scheme described on Figure 2.18 and the accompanying text. A
more stable and responsive scheme uses the inlet cooling water flow and temperature of
the outlet gas in a feedforward/feedback control as the slave in a cascade control scheme
with an analyzer on the outlet stream as the master control loop. Modify Figure 2.18 to
show this improved control scheme.
Chapter 2 Page 10
• See Drawing 2.9-A-001/1
2.10 Consider the system shown in Figure 2.21. Many local regulatory agencies require that
the opacity of the flue gas exiting the furnace or boiler stack be measured. Opacity is a
measure of the quality of the combustion. If combustion is inefficient, then the flue gas
will include soot and/or unburned fuel which will decrease the opacity of the exiting gas.
If the opacity exceeds a certain point, action must be taken to increase the air to fuel ratio
in order to insure that the discharge is within acceptable limits. Duplicate the scheme
shown in Figure 2.21 and add a safety automation system control scheme that will take
“last resort” action to add air into the burner if the opacity meter reaches its low-low
alarm, analysis point.
• See Drawing 2.10-A-001/1
2.11 Consider the neutralization system shown in Figure 2.14. This scheme can be improved
by adding a cascade control loop that uses the outlet pH reading as the master dependent
variable. Duplicate the scheme shown in Figure 2.14 and show how this improved
scheme would be depicted.

Exploring the Variety of Random

Imagine the difference between a preacher solemnly warning his
hearers that the consequences of inattention may be everlasting
torment, and a politician warning the Government that inattention
may lead to a deficit! The truth is, that however terrible may be the
earthly consequences of imprudence and of sin, they sink into
complete insignificance before the menaces of the Church; nor is
there, on the other hand, any worldly success that can be proposed
as a motive comparable to the permanent happiness of Paradise.
The good and the bad things of this world have alike the fatal
defect, as subjects for eloquence, that they equally end in death;
and as death is near to all of us, we see the end to both. The
secular preacher is like a man who predicts a more or less
comfortable journey, which comes to the same end in any case. A
philosophic hearer is not very greatly elated by the promise of
comforts so soon to be taken away, nor is he overwhelmed by the
threat of evils that can but be temporary. Hence, in all matters
belonging to this world only, the tone of quiet advice is the
reasonable and appropriate tone, and it is that of the doctor and
lawyer; but in matters of such tremendous import as eternal
happiness and misery the utmost energy of eloquence can never be
too great for the occasion; so that if a preacher can threaten like
peals of thunder, and appal like flashes of lightning, he may use such
terrible gifts without any disproportionate excess. On the other
hand, if he has any charm of language, any brilliancy of imagination,
there is nothing to prevent him from alluring his hearers to the paths
of virtue by the most lavish and seductive promises. In short, his
opportunities in both directions are of such a nature that
exaggeration is impossible; and all his power, all his charm, are as
free to do their utmost as an ocean wave in a tempest or the
nightingale in the summer woods.
I cannot quit the subject of clerical oratory without noticing one of
its marked characteristics. The priest is not in a position of
disinterested impartiality, like a man of science, who is ready to
renounce any doctrine when he finds evidence against it. The priest
is an advocate whose life-long pleading must be in favor of the
Church as he finds her, and in opposition to her adversaries. To
attack adversaries is therefore one of the recognized duties of his
profession; and if he is not a man of uncommon fairness, if he has
not an inborn love of justice which is rare in human nature, he will
not only attack his adversaries but misrepresent them. There is even
a worse danger than simple misrepresentation. A priest may possibly
be a man of a coarse temper, and if he is so he will employ the
weapons of outrage and vituperation, knowing that he can do so
with impunity. One would imagine that these methods must
inevitably repel and displease women, but there is a very peculiar
reason why they seldom have this effect. A highly principled woman
is usually so extremely eager to be on the side of what is right that
suspension of judgment is most difficult for her. Any condemnation
uttered by a person she is accustomed to trust has her approval on
the instant. She cannot endure to wait until the crime is proved, but
her feelings of indignation are at once aroused against the supposed
criminal on the ground that there must be clear distinctions between
right and wrong. The priest, for her, is the good man,—the man on
the side of God and virtue; and those whom he condemns are the
bad men,—the men on the side of the Devil and vice. This being so,
he may deal with such men as roughly as he pleases. Nor have
these men the faintest chance of setting themselves right in her
opinion. She quietly closes the avenues of her mind against them;
she declines to read their books; she will not listen to their
arguments. Even if one of them is a near relation whose opinions
inflict upon her what she calls “the deepest distress of mind,” she
will positively prefer to go on suffering such distress until she dies,
rather than allow him to remove it by a candid exposition of his
views. She prefers the hostile misrepresentation that makes her
miserable, to an authentic account of the matter that would relieve
her anguish.
Part III.—Association.
The association of clergymen with ladies in works of charity affords
continual opportunities for the exercise of clerical influence over
women. A partnership in good works is set up which establishes
interesting and cordial relations, and when the lady has
accomplished some charitable purpose she remembers for long
afterwards the clergyman without whose active assistance her
project might have fallen to the ground. She sees in the clergyman a
reflection of her own goodness, and she feels grateful to him for
lending his masculine sense and larger experience to the realization
of her ideas. There are other cases of a different nature in which the
self-esteem of the lady is deeply gratified when she is selected by
the clergyman as being more capable of devoted effort in a sacred
cause than women of inferior piety and strength of mind. This kind
of clerical selection is believed to be very influential in furthering
clerical marriages. The lady is told that she will serve the highest of
all causes by lending a willing ear to her admirer. Every reader will
remember how thoroughly this idea is worked out in “Jane Eyre,”
where St. John urges Jane to marry him on the plain ground that
she would be a valuable fellow-worker with a missionary. Charlotte
Brontë was, indeed, so strongly impressed with this aspect of clerical
influence that she injured the best and strongest of her novels by an
almost wearisome development of that episode.
Clerical influence is immensely aided by the possession of leisure.
Without underrating the self-devotion of hard-working clergymen
(which is all the more honorable to them that they might take life
more easily if they chose), we see a wide distinction, in point of
industry, between the average clergyman and the average solicitor,
for example. The clergyman has leisure to pay calls, to accept many
invitations, and to talk in full detail about the interests that he has in
common with his female friends. The solicitor is kept to his office by
strictly professional work requiring very close application and
allowing no liberty of mind.
Much might be said about the effect of clerical leisure on clerical
manners. Without leisure it is difficult to have such quiet and
pleasant manners as the clergy generally have. Very busy men
generally seem preoccupied with some idea of their own which is not
what you are talking about, but a leisurely man will give hospitality
to your thought. A busy man wants to get away, and fidgets you; a
man of leisure dwells with you, for the time, completely. Ladies are
exquisitely sensitive to these differences, and besides, they are
generally themselves persons of leisure. Overworked people often
confound leisure with indolence, which is a great mistake. Leisure is
highly favorable to intelligence and good manners; indolence is
stupid, from its dislike to mental effort, and ill-bred, from the habit
of inattention.
The feeling of women towards custom draws them strongly to the
clergy, because a priesthood is the instinctive upholder of ancient
customs and ceremonies, and steadily maintains external decorum.
Women are naturally more attracted by custom than we are. A few
men have an affectionate regard for the sanctities of usage, but
most men only submit to them from an idea that they are generally
helpful to the “maintenance of order;” and if women could be
supposed absent from a nation for a time, it is probable that
external observances of all kinds would be greatly relaxed. Women
do not merely submit passively to custom; they uphold it actively
and energetically, with a degree of faith in the perfect
reasonableness of it which gives them great decision in its defence.
It seems to them the ultimate reason from which there is no appeal.
Now, in the life of every organized Church there is much to gratify
this instinct, especially in those which have been long established.
The recurrence of holy seasons, the customary repetition of certain
forms of words, the observance at stated intervals of the same
ceremonies, the adherence to certain prescribed decencies or
splendors of dress, the reservation of sacred days on which labor is
suspended, give to the religious life a charm of customariness which
is deeply gratifying to good, order-loving women. It is said that
every poet has something feminine in his nature; and it is certainly
observable that poets, like women, are tenderly affected by the
recurrence of holy seasons, and the observance of fixed religious
rites. I will only allude to Keble’s “Christian Year,” because in this
instance it might be objected that the poet was secondary to the
Christian; but the reader will find instances of the same sentiment in
Tennyson, as, for example, in the profoundly affecting allusions to
the return of Christmas in “In Memoriam.” I could not name another
occupation so closely and visibly bound up with custom as the
clerical profession, but for the sake of contrast I may mention one or
two others that are completely disconnected from it. The profession
of painting is an example, and so is that of literature. An artist, a
writer, has simply nothing whatever to do with custom, except as a
private man. He may be an excellent and a famous workman without
knowing Sunday from week-day or Easter from Lent. A man of
science is equally unconnected with traditional observances.
It may be a question whether a celibate or a married clergy has the
greater influence over women.
There are two sides to this question. The Church of Rome is, from
the worldly point of view, the most astute body of men who have
ever leagued themselves together in a corporation; and that Church
has decided for celibacy, rejecting thereby all the advantages to be
derived from rich marriages and good connections. In a celibate
church the priest has a position of secure dignity and independence.
It is known from the first that he will not marry, so there is no idle
and damaging gossip about his supposed aspirations after fortune,
or tender feelings towards beauty. Women can treat him with
greater confidence than if he were a possible suitor, and then can
confess to him, which is felt to be difficult with a married or a
marriageable clergy. By being decidedly celibate the clergy avoid the
possible loss of dignity which might result from allying themselves
with families in a low social position. They are simply priests, and
escape all other classification. A married man is, as it were, made
responsible for the decent appearance, the good manners, and the
proper conduct of three different sets of people. There is the family
he springs from, there is his wife’s family, and, lastly, there is the
family in his own house. Any one of these may drag a man down
socially with almost irresistible force. The celibate priest is only
affected by the family he springs from, and is generally at a distance
from that. He escapes the invasion of his house by a wife’s relations,
who might possibly be vulgar, and, above all, he escapes the
permanent degradation of a coarse and ill-dressed family of his own.
No doubt, from the Christian point of view, poverty is as honorable
as wealth; but from the worldly point of view its visible imperfections
are mean, despicable, and even ridiculous. In the early days of
English Protestants the liberty to marry was ruinous to the social
position of the clergy. They generally espoused servant-girls or “a
lady’s maid whose character had been blown upon, and who was
therefore forced to give up all hope of catching the steward.”[17]
Queen Elizabeth issued “special orders that no clergyman should
presume to marry a servant-girl without the consent of the master or
mistress.” “One of the lessons most earnestly inculcated on every girl
of honorable family was to give no encouragement to a lover in
orders; and if any young lady forgot this precept she was almost as
much disgraced as by an illicit amour.” The cause of these low
marriages was simply poverty, and it is needless to add that they
increased the evil. “As children multiplied and grew, the household of
the priest became more and more beggarly. Holes appeared more
and more plainly in the thatch of his parsonage and in his single
cassock. His boys followed the plough, and his girls went out to
service.”
When clergymen can maintain appearances they gain one advantage
from marriage which increases their influence with women. The
clergyman’s wife is almost herself in holy orders, and his daughter
often takes an equally keen interest in ecclesiastical matters. These
“clergywomen,” as they have been called, are valuable allies,
through whom much may be done that cannot be effected directly.
This is the only advantage on the side of marriage, and it is but
relative; for a celibate clergy has also its female allies who are
scarcely less devoted; and in the Church of Rome there are great
organized associations of women entirely under the control of
ecclesiastics. Again, there is a lay element in a clergyman’s family
which brings the world into his own house, to the detriment of its
religious character. The sons of the clergy are often anything but
clerical in feeling. They are often strongly laic, and even sceptical, by
a natural reaction from ecclesiasticism. On the whole, therefore, it
seems certain that an unmarried clergy more easily maintains both
its own dignity and the distinction between itself and the laity.
Auricular confession is so well known as a means of influencing
women that I need scarcely do more than mention it; but there is
one characteristic of it which is little understood by Protestants. They
fancy (judging from Protestant feelings of antagonism) that
confession must be felt as a tyranny. A Roman Catholic woman does
not feel it to be an infliction that the Church imposes, but a relief
that she affords. Women are not naturally silent sufferers. They like
to talk about their anxieties and interests, especially to a patient and
sympathetic listener of the other sex who will give them valuable
advice. There is reason to believe that a good deal of informal
confession is done by Protestant ladies; in the Church of Rome it is
more systematic and leads to a formal absolution. The subject which
the speaker has to talk about is that most interesting of all subjects,
self. In any other place than a confessional to talk about self at any
length is an error; in the confessional it is a virtue. The truth is that
pious Roman Catholic women find happiness in the confessional and
try the patience of the priests by minute accounts of trifling or
imaginary sins. No doubt confession places an immense power in the
hands of the Church, but at an incalculable cost of patience. It is not
felt to weigh unfairly on the laity, because the priest who to-day has
forgiven your faults will to-morrow kneel in penitence and ask
forgiveness for his own. I do not see in the confessional so much an
oppressive institution as a convenience for both parties. The woman
gets what she wants,—an opportunity of talking confidentially about
herself; and the priest gets what he wants,—an opportunity of
learning the secrets of the household.
Nothing has so powerfully awakened the jealousy of laymen as this
institution of the confessional. The reasons have been so fully
treated by Michelet and others, and are in fact so obvious, that I
need not repeat them.
The dislike for priests that is felt by many Continental laymen is
increased by a cause that helps to win the confidence of women.
“Observe,” the laymen say, “with what art the priest dresses so as to
make women feel that he is without sex, in order that they may
confess to him more willingly. He removes every trace of hair from
his face, his dress is half feminine, he hides his legs in petticoats, his
shoulders under a tippet, and in the higher ranks he wears jewelry
and silk and lace. A woman would never confess to a man dressed
as we are, so the wolf puts on sheep’s clothing.”
Where confession is not the rule the layman’s jealousy is less acrid
and pungent in its expression, but it often manifests itself in milder
forms. The pen that so clearly delineated the Rev. Charles
Honeyman was impelled by a layman’s natural and pardonable
jealousy. A feeling of this kind is often strong in laymen of mature
years. They will say to you in confidence, “Here is a man about the
age of one of my sons, who knows no more concerning the
mysteries of life and death than I do, who gets what he thinks he
knows out of a book which is as accessible to me as it is to him, and
yet who assumes a superiority over me which would only be
justifiable if I were ignorant and he enlightened. He calls me one of
his sheep. I am not a sheep relatively to him. I am at least his equal
in knowledge, and greatly his superior in experience. Nobody but a
parson would venture to compare me to an animal (such a stupid
animal too!) and himself to that animal’s master. His one real and
effective superiority is that he has all the women on his side.”
You poor, doubting, hesitating layman, not half so convinced as the
ladies of your family, who and what are you in the presence of a
man who comes clothed with the authority of the Church? If you
simply repeat what he says, you are a mere echo, a feeble repetition
of a great original, like the copy of a famous picture. If you try to
take refuge in philosophic indifference, in silent patience, you will be
blamed for moral and religious inertia. If you venture to oppose and
discuss, you will be the bad man against the good man, and as sure
of condemnation as a murderer when the judge is putting on the
black cap. There is no resource for you but one, and that does not
offer a very cheering or hopeful prospect. By the exercise of angelic
patience, and of all the other virtues that have been preached by
good men from Socrates downwards, you may in twenty or thirty
years acquire some credit for a sort of inferior goodness of your
own,—a pinchbeck goodness, better than nothing, but not in any
way comparable to the pure golden goodness of the priest; and
when you come to die, the best that can be hoped for your
disembodied soul will be mercy, clemency, indulgence; not
approbation, welcome, or reward.

ESSAY XIV.
WHY WE ARE APPARENTLY BECOMING LESS
RELIGIOUS.
T has happened to me on more than one occasion to have to
examine papers left by ladies belonging to the last generation,
who had lived in the manner most esteemed and respected by the
general opinion of their time, and who might, without much risk of
error, be taken for almost perfect models of English gentlewomen as
they existed before the present scientific age. The papers left by
these ladies consisted either of memoranda of their private thoughts,
or of thoughts by others which seemed to have had an especial
interest for them. I found that all these papers arranged themselves
naturally and inevitably under two heads: either they concerned
family interests and affections, or they were distinctly religious in
character, like the religious meditations we find in books of devotion.
There may be nothing extraordinary in this. Thousands of other
ladies may have left religious memoranda; but consider what a
preponderance of religious ideas is implied when written thoughts
are entirely confined to them! The ladies in question lived in the first
half of the nineteenth century, a period of great intellectual ferment,
of the most important political and social changes, and of wonderful
material progress; but they did not seem to have taken any real
interest in these movements. The Bible and the commentaries of the
clergy satisfied not only their spiritual but also their intellectual
needs. They seem to have desired no knowledge of the universe, or
of the probable origin and future of the human race, which the Bible
did not supply. They seem to have cared for no example of human
character and conduct other than the scriptural examples.
This restfulness in Biblical history and philosophy, this substitution of
the Bible for the world as a subject of study and contemplation, this
absence of desire to penetrate the secrets of the world itself, this
want of aspiration after any ideal more recent than the earlier ages
of Christianity, permitted a much more constant and uninterrupted
dwelling with what are considered to be religious ideas than is
possible to any active and inquiring mind of the present day. Let it
be supposed, for example, that a person to whom the Bible was
everything desired information about the origin of the globe, and of
life upon it; he would refer to the Book of Genesis as the only
authority, and this reference would have the character of a religious
act, and he would get credit for piety on account of it; whilst a
modern scientific student would refer to some great modern
paleontologist, and his reference would not have the character of a
religious act, nor bring him any credit for piety; yet the prompting
curiosity, the desire to know about the remote past, would be
exactly the same in both cases. And I think it may be easily shown
that if the modern scientific student appears to be less religious than
others think he ought to be, it is often because he possesses and
uses more abundant sources of information than those which were
accessible to the ancient Jews. It is not his fault if knowledge has
increased; he cannot be blamed if he goes where information is
most copious and most exact; yet his preference for such
information gives an unsanctified aspect to his studies. The study of
the most ancient knowledge wears a religious aspect, but the study
of modern knowledge appears to be non-religious.
Again, when we come to the cultivation of the idealizing faculties, of
the faculties which do not seek information merely, but some kind of
perfection, we find that the very complexity of modern life, and the
diversity of the ideal pleasures and perfections that we modern men
desire, have a constant tendency to take us outside of strictly
religious ideals. As long as the writings which are held to be sacred
supply all that our idealizing faculties need, so long will our
imaginative powers exercise themselves in what is considered to be
a religious manner, and we shall get credit for piety; but when our
minds imagine what the sacred writers could not or did not conceive,
and when we seek help for our imaginative faculty in profane
writers, we appear to be less religious. So it is with the desire to
study and imitate high examples of conduct and character. There is
no nobler or more fruitful instinct in man than a desire like this,
which is possible only to those who are at once humble and aspiring.
An ancient Jew who had this noble instinct could satisfy it by reading
the sacred books of the Hebrews, and so his aspiration appeared to
be wholly religious. It is not so with an active-minded young
Englishman of the present day. He cannot find the most inspiriting
models amongst the ancient Hebrews, for the reason that their life
was altogether so much simpler and more primitive than ours. They
had nothing that can seriously be called science; they had not any
organized industry; they had little art, and hardly any secular
literature, so that in these directions they offer us no examples to
follow. Our great inspiriting examples in these directions are to be
found either in the Renaissance or in recent times, and therefore in
profane biography. From this it follows that an active modern mind
seems to study and follow non-religious examples, and so to differ
widely, and for the worse, from the simpler minds of old time, who
were satisfied with the examples they found in their Bibles. This
appearance is misleading; it is merely on the surface; for if we go
deeper and do not let ourselves be deceived by the words “sacred”
and “profane,” we shall find that when a simple mind chooses a
model from a primitive people, and a cultivated one chooses a model
from an advanced people, and from the most advanced class in it,
they are both really doing the same thing, namely, seeking ideal help
of the kind which is best for each. Both of them are pursuing the
same object,—a mental discipline and elevation which may be
comprised under the general term virtue; the only difference being
that one is studying examples of virtue in the history of the ancient
Jews, whilst the other finds examples of virtue more to his own
special purpose in the lives of energetic Englishmen, Frenchmen, or
Germans.
A hundred such examples might be mentioned, for every occupation
worth following has its own saints and heroes; but I will confine
myself to two. The first shall be a French gentleman of the
eighteenth century, to whom life offered in the richest profusion
everything that can tempt a man to what is considered an excusable
and even a respectable form of idleness. He had an independent
fortune, excellent health, a good social position, and easy access to
the most lively, the most entertaining, the most amiable society that
ever was, namely, that of the intelligent French nobility before the
Revolution. There is no merit in renouncing what we do not enjoy;
but he enjoyed all pleasant things, and yet renounced them for a
higher and a harder life. At the age of thirty-two he retired to the
country, made a rule of early rising and kept it, sallied forth from his
house every morning at five, went and shut himself up in an old
tower with a piece of bread and a glass of water for his breakfast,
worked altogether eleven or twelve hours a day in two sittings, and
went to bed at nine. This for eight months in the year, regularly, the
remaining four being employed in scientific and administrative work
at the Jardin des Plantes. He went on working in this way for forty
years, and in the whole course of that time never let pass an ill-
considered page or an ill-constructed sentence, but always did his
best, and tried to make himself able to do better.
Such was the great life of Buffon; and in our own time another great
life has come to its close, inferior to that of Buffon only in this, that
as it did not begin in luxury, the first renunciation was not so difficult
to make. Yet, however austere his beginnings, it is not a light or
easy thing for a man to become the greatest intellectual worker of
his time, so that one of his days (including eight hours of steady
nocturnal labor) was equivalent to two or more of our days. No man
of his time in Europe had so vast a knowledge of literature and
science in combination; yet this knowledge was accompanied by
perfect modesty and by a complete indifference to vulgar distinctions
and vain successes. For many years he was the butt of coarse and
malignant misrepresentation on the part of enemies who easily
made him odious to a shallow society; but he bore it with perfect
dignity, and retained unimpaired the tolerance and charity of his
nature. His way of living was plain and frugal; he even contented
himself with narrow dwellings, though the want of space must have
occasioned frequent inconvenience to a man of his pursuits. He
scrupulously fulfilled his domestic duties, and made use of his
medical education in ministering gratuitously to the poor. Such was
his courage that when already advanced in life he undertook a
gigantic task, requiring twenty years of incessant labor; and such
were his industry and perseverance that he brought it to a splendidly
successful issue. At length, after a long life of duty and patience,
after bearing calumny and ridicule, he was called to endure another
kind of suffering,—that of incessant physical pain. This he bore with
perfect fortitude, retaining to the last his mental serenity, his interest
in learning, and a high-minded patriotic thoughtfulness for his
country and its future, finding means in the midst of suffering to
dictate long letters to his fellow-citizens on political subjects, which,
in their calm wisdom, stood in the strongest possible contrast to the
violent party writing of the hour.
Such was the great life of Littré; and now consider whether he who
studies lives like these, and wins virtue from their austere example,
does not occupy his thoughts with what would have been considered
religious aspirations, if these two men, instead of being Frenchmen
of the eighteenth and nineteenth centuries, had happened to be
ancient Jews. If it had been possible for so primitive a nation as the
Jewish to produce men of such steady industry and so large a
culture, we should have read the story of their lives in the Jewish
sacred books, and then it would have been a part of the popular
religion to study them, whereas now the study of such biography is
held to be non-religious, if not (at least in the case of Littré)
positively irreligious. Yet surely when we think of the virtues which
made these lives so fruitful, our minds are occupied in a kind of
religious thought; for are we not thinking of temperance, self-
discipline, diligence, perseverance, patience, charity, courage, hope?
Were not these men distinguished by their aspiration after higher
perfection, by a constant desire to use their talents well, and by a
vigilant care in the employment of their time? And are not these
virtues and these aspirations held to be parts of a civilized man’s
religion, and the best parts?
The necessity for an intellectual expansion beyond the limits of the
Bible was felt very strongly at the time of the Renaissance, and
found ample satisfaction in the study of the Greek and Latin classics.
There are many reasons why women appear to be more religious
than men; and one of them is because women study only one
collection of ancient writings, whilst men have been accustomed to
study three; consequently that which women study (if such a word is
applicable to devotional, uncritical reading) occupies their minds far
more exclusively than it occupies the mind of a classical scholar. But,
though the intellectual energies of men were for a time satisfied with
classical literature, they came at length to look outside of that as
their fathers had looked outside of the Bible. Classical literature was
itself a kind of religion, having its own sacred books; and it had also
its heretics,—the students of nature,—who found nature more
interesting than the opinions of the Greeks and Romans. Then came
the second great expansion of the human mind, in the midst of
which we ourselves are living. The Renaissance opened for it a world
of mental activity which had the inappreciable intellectual advantage
of lying well outside of the popular beliefs and ideas, so that
cultivated men found in it an escape from the pressure of the
uneducated; but the new scientific expansion offers us a region
governed by laws of a kind peculiar to itself, which protect those
who conform to them against every assailant. It is a region in which
authority is unknown, for, however illustrious any great man may
appear in it, every statement that he makes is subject to verification.
Here the knowledge of ancient writers is continually superseded by
the better and more accurate knowledge of their successors; so that
whereas in religion and learning the most ancient writings are the
most esteemed, in science it is often the most recent, and even
these have no authority which may not be called in question freely
by any student. The new scientific culture is thus encouraging a
habit of mind different from old habits, and which in our time has
caused such a degree of separation that the most important and the
most interesting of all topics are those upon which we scarcely dare
to venture for fear of being misunderstood.
If I had to condense in a short space the various reasons why we
are apparently becoming less religious, I should say that it is
because knowledge and feeling, embodied or expressed in the
sciences and arts, are now too fully and too variously developed to
remain within the limits of what is considered sacred knowledge or
religious emotion. It was possible for them to remain well within
those limits in ancient times, and it is still possible for a mind of very
limited activity and range to dwell almost entirely in what was known
or felt at the time of Christ; but this is not possible for an energetic
and inquiring mind, and the consequence is that the energetic mind
will seem to the other, by contrast, to be negligent of holy things,
and too much occupied with purely secular interests and concerns. A
great misunderstanding arises from this, which has often had a
lamentable effect on intercourse between relations and friends.
Pious ladies, to whom theological writings appear to contain almost
everything that it is desirable to know, often look with secret
misgiving or suspicion on young men of vigorous intellect who
cannot rest satisfied with the old knowledge, and what such ladies
vaguely hear of the speculations of the famous scientific leaders
inspires them with profound alarm. They think that we are becoming
less religious because theological writings do not occupy the same
space in our time and thoughts as they do in theirs; whereas, if such
a matter could be put to any kind of positive test, it would probably
be found that we know more, even of their own theology, than they
do, and that, instead of being indifferent to the great problems of
the universe, we have given to such problems an amount of careful
thought far surpassing, in mental effort, their own simple
acquiescence. The opinions of a thoughtful and studious man in the
present day have never been lightly come by; and if he is supposed
to be less religious than his father or his grandfather it may be that
his religion is different from theirs, without being either less earnest
or less enlightened. There is, however, one point of immense
importance on which I believe that we really are becoming less
religious, indeed on that point we seem to be rapidly abandoning the
religious principle altogether; but the subject is of too much
consequence to be treated at the end of an Essay.
T
ESSAY XV.
HOW WE ARE REALLY BECOMING LESS RELIGIOUS.
HE reader may remember how, after the long and unsuccessful
siege of Syracuse, the Athenian general Nikias, seeing his
discouraged troops ill with the fever from the marshes, determined
to raise the siege; and that, when his soldiers were preparing to
retreat, and striking their tents for the march, there occurred an
eclipse of the moon. Nikias, in his anxiety to know what the gods
meant by this with reference to him and his army, at once consulted
a soothsayer, who told him that he would incur the Divine anger if
he did not remain where he was for three times nine days. He
remained, doing nothing, allowing his troops to perish and his ships
to be shut up by a line of the enemy’s vessels chained together
across the entrance of the port. At length the three times nine days
came to an end, and what was left of the Athenian army had to get
out of a situation that had become infinitely more difficult during its
inaction. The ships tried to get out in vain; the army was able to
retreat by land, but only to be harassed by the enemy, and finally
placed in such distress that it was compelled to surrender. Most of
the remnant died miserably in the old quarries of Syracuse.
The conduct of Nikias throughout these events was in the highest
degree religious. He was fully convinced that the gods concerned
themselves about him and his doings, that they were watching over
him, and that the eclipse was a communication from them not to be
neglected without a breach of religious duty. He, therefore, in the
spirit of the most perfect religious faith, which we are compelled to
admire for its sincerity and thoroughness, shut his eyes resolutely to
all the visible facts of a situation more disastrous every day, and
attended only to the invisible action of the invisible gods, of which
nothing could be really known by him. For twenty-seven days he
went on quietly sacrificing his soldiers to his faith, and only moved at
last when he believed that the gods allowed it.
In contrast with this, let us ask what we think of an eclipse
ourselves, and how far any religious emotion, determinant of action
or of inaction, is connected with the phenomenon in our experience.
We know, in the first place, that eclipses belong to the natural order,
and we do not feel either grateful to the supernatural powers, or
ungrateful, with regard to them. Even the idea that eclipses
demonstrate the power of God is hardly likely to occur to us, for we
constantly see terrestrial objects eclipsed by cast shadows; and the
mere falling of a shadow is to us only the natural interruption of light
by the intervention of any opaque object. In the true theory of
eclipses there is absolutely no ground whatever for religious
emotion, and accordingly the phenomenon is now entirely
disconnected from religious ideas. The consequence is that where
the Athenian general had a strong motive for religious emotion, a
motive so strong that he sacrificed his army to the supposed will of
Heaven, a modern general in the same situation would feel no
emotion and make no sacrifice.
If this process stopped at eclipses the result would be of little
importance, as eclipses of the celestial bodies are not frequently
visible, and to lose the opportunity of emotion which they present is
not a very sensible loss. But so far is the process from stopping at
eclipses, that exactly the same process is going on with regard to
thousands of other phenomena which are one by one, yet with
increasing rapidity, ceasing to be regarded as special manifestations
of Divine will, and beginning to be regarded as a part of that order
of nature with which, to quote Professor Huxley’s significant
language, “nothing interferes.” Every one of these transferrences
from supernatural government to natural order deprives the religious
sentiment of one special cause or motive for its own peculiar kind of
emotion, so that we are becoming less and less accustomed to such
emotion (as the opportunities for it become less frequent), and more
and more accustomed to accept events and phenomena of all kinds
as in that order of nature “with which nothing interferes.”
This single mental conception of the unfailing regularity of nature is
doing more in our time to affect the religious condition of thoughtful
people than could be effected by many less comprehensive
conceptions.
It has often been said, not untruly, that merely negative arguments
have little permanent influence over the opinions of men, and that
institutions which have been temporarily overthrown by negation will
shortly be set up again, and flourish in their old vigor, unless
something positive can be found to supply their place. But here is a
doctrine of a most positive kind. “The order of nature is invariably
according to regular sequences.” It is a doctrine which cannot be
proved, for we cannot follow all the changes which have ever taken
place in the universe; but, although incapable of demonstration, it
may be accepted until something happens to disprove it; and it is
accepted, with the most absolute faith, by a constantly increasing
number of adherents.
To show how this doctrine acts in diminishing religious emotion by
taking away the opportunity for it, let me narrate an incident which
really occurred on a French line of railway in the winter of 1882. The
line, on which I had travelled a few days before, passes between a
river and a hill. The river has a rocky bed and is torrential in winter;
the hill is densely covered with a pine forest coming down to the
side of the line. The year 1882 had been the rainiest known in
France for two centuries, and the roots of the trees on the edge of
this pine forest had been much loosened by the rain. In
consequence of this, two large pine-trees fell across the railway early
one morning, and soon afterwards a train approached the spot by
the dim light of early dawn. There was a curve just before the
engine reached the trees, and it had come rapidly for several miles
down a decline. The driver reversed his steam, the engine and
tender leaped over the trees, and then went over the embankment
to a place within six feet of the rapid river. The carriages remained
on the line, but were much broken. Nobody was killed; nobody was
seriously injured. The remarkable escape of the passengers was
accounted for as follows by the religious people in the neighborhood.
There happened to be a priest in the train, and at the time when the
shock took place he made what is called “a pious ejaculation.” This,
it was said, had saved the lives of the passengers. In the ages of
faith this explanation would have been received without question;
but the notion of natural sequences—Professor Huxley’s “order with
which nothing interferes”—had obtained such firm hold on the minds
of the townsmen generally that they said the priest was trying to
make ecclesiastical capital out of an occurrence easily explicable by
natural causes. They saw nothing supernatural either in the
production of the accident or its comparative harmlessness. The
trickling of much water had denuded the roots of the trees, which
fell because they could not stand with insufficient roothold; the lives
of the passengers were saved because they did not happen to be in
the most shattered carriage; and the men on the engine escaped
because they fell on soft ground, made softer still by the rain. It was
probable, too, they said, that if any beneficent supernatural
interference had taken place it would have maintained the trees in
an erect position, by preventive miracle, and so spared the slight
injuries which really were inflicted, and which, though treated very
lightly by others because there were neither deaths nor
amputations, still caused suffering to those who had to bear them.
Now if we go a little farther into the effects of this accident on the
minds of the people who shared in it, or whose friends had been
imperilled by it, we shall see very plainly the effect of the modern
belief in the regularity of natural sequences. Those who believed in
supernatural intervention would offer thanksgivings when they got
home, and probably go through some special religious thanksgiving
services for many days afterwards; those who believed in the
regularity of natural sequences would simply feel glad to have
escaped, without any especial sense of gratitude to supernatural
powers. So much for the effect as far as thanksgiving is concerned;
but there is another side of the matter at least equally important
from the religious point of view,—that of prayer. The believers in
supernatural interference would probably, in all their future railway
journeys, pray to be supernaturally protected in case of accident, as
they had been in 1882; but the believers in the regularity of natural
sequences would only hope that no trees had fallen across the line,
and feel more than usually anxious after long seasons of rainy
weather. Can there be a doubt that the priest’s opinion, that he had
won safety by a pious ejaculation, was highly favorable to his
religious activity afterwards, whilst the opinion of the believers in
“the natural order with which nothing interferes” was unfavorable
both to prayer and thanksgiving in connection with railway
travelling?
Examples of this kind might easily be multiplied, for there is hardly
any enterprise that men undertake, however apparently
unimportant, which cannot be regarded both from the points of view
of naturalism and supernaturalism; and in every case the naturalist
manner of regarding the enterprise leads men to study the probable
influence of natural causes, whilst the supernaturalist opinion leads
them to propitiate supernatural powers. Now, although some new
sense may come to be attached to the word “religion” in future
ages, so that it may come to mean scientific thoroughness,
intellectual ingenuousness, or some other virtue that may be
possessed by a pure naturalist, the word has always been
understood, down to the present time, to imply a constant
dependence upon the supernatural; and when I say that we are
becoming less religious, I mean that from our increasing tendency to
refer everything to natural causes the notion of the supernatural is
much less frequently present in our minds than it was in the minds
of our forefathers. Even the clergy themselves seem to be following
the laity towards the belief in natural law, at least so far as matter is
concerned. The Bishop of Melbourne, in 1882, declined to order
prayers for rain, and gave his reason honestly, which was that
material phenomena were under the control of natural law, and
would not be changed in answer to prayer. The Bishop added that
prayer should be confined to spiritual blessings. Without disputing
the soundness of this opinion, we cannot help perceiving that if it
were generally received it would put an end to one half of the
religious activity of the human race; for half the prayers and half the
thanksgivings addressed to the supernatural powers are for material
benefits only. It is possible that, in the future, religious people will
cease to pray for health, but take practical precautions to preserve
it; that they will cease to pray for prosperity, but study the natural
laws which govern the wealth of nations; that they will no longer
pray for the national fleets and armies, but see that they are well
supplied and intelligently commanded. All this and much more is
possible; but when it comes to pass the world will be less religious
than it was when men believed that every pestilence, every famine,
every defeat, was a chastisement specially, directly, and intentionally
inflicted by an angry Deity. Even now, what an immense step has
been made in this direction! In the fearful description of the
pestilence at Florence, given with so much detail by Boccaccio, he
speaks of “l’ira di Dio a punire la iniquità degli uomini con quella
pestilenza;” and he specially implies that those who sought to avoid
the plague by going to healthier places in the country deceived
themselves in supposing that the wrath of God would not follow
them whithersoever they went. That is the old belief expressing
itself in prayers and humiliations. It is still recognized officially. If the
plague could occur in a town on the whole so well cared for as
modern London, the language of Boccaccio would still be used in the
official public prayers; but the active-minded practical citizens would
be thinking how to destroy the germs, how to purify air and water.
An instance of this divergence occurred after the Egyptian war of
1882. The Archbishop of York, after the battle of Tel-el-Kebir,
ordered thanksgivings to be offered in the churches, on the ground
that God was in Sir Garnet Wolseley’s camp and fought with him
against the Egyptians, which was a survival of the antique idea that
national deities fought with the national armies. On this a Member of
Parliament, Mr. George Palmer, said to his constituents in a public
meeting at Reading, “At the same time I cannot agree with the
prayers that have been made in churches. Though I respect the

Chapter 2 Page 1 Designing Controls for the Process Industries 1st Seames Solution Manual Full chapter at: https://testbankbell.com/product/designing- controls-for-the-process-industries-1st-seames-solution- manual/ Chapter 2 Problem Solutions 2.1 Define the following terms: measurement variable, control variable, dependent variable, valve position, operational objective, control objective, controller, setpoint, measurement error, controller output, manual mode, high-high level alarm, low-low level alarm, air fail open, and air fail closed. • Measurement Variable: The subset of the dependent variables affected by changes to the process that are used to determine the effect of a change to the process by a related independent (control) variable. For feedback control loops measurement variables are also used to evaluate the effectiveness of changes in the control variable. Examples: flow rate, pressure, temperature, level, motor speed, and material properties such as chemical composition. • Control Variable: An independent variable which is used in a process control loop to keep a portion of the process at its desired condition. The main control variables are: control valves, motor speed, electrical supply interruption time, and electrical current resistance. • Dependent Variable: These are variables affected by changes to the process made by a related independent variable. They are used to determine the condition of the process. When used in a feedback control loop, they are measurement variables. When used in a feedforward control loop, they are measurement variables related to disturbance variables. When used in the slave feedback control loop of a cascade control scheme, they are related variables. Examples: flow rate, pressure, temperature, level, and material properties such as chemical composition. • Valve Position: The valve opening area. This is used to adjust the rate of flow through and the pressure drop incurred by a process fluid in a control valve in order to achieve the process or operational objectives of a unit operation. Valve position is typically measured on a scale from 0 to 100%. • Operational Objective: A functional goal of a unit operation. It defines the unit operation’s purpose. Tasks are designed to accomplish the operational objectives. • Control Objective: A goal of the plant automation system. It defines the purpose for the controls applied to a given unit operation.
  • 6. Chapter 2 Page 2 • Controller: The portion of the control system that determines how the related control variable shall be adjusted to meet the control objectives of the control loop. A typical controller compares the measurement variable to a setpoint to generate an error. The error is used by the controller in a control algorithm to determine an output for the control variable. • Setpoint: The desired value of the measurement variable. It is specified by an operator or by another part of the plant automation system. • Measurement Error: The difference between the measured value of the measurement variable and the setpoint, as calculated by the controller. • Controller Output: The change to the control variable requested by the controller in response to the measurement error. • Manual Mode: When an operator overrides the controller output, in order to impose their own output for the control variable. • High-High Level Alarm: An additional piece of safety equipment, which activates once the level of a unit operation has exceeded the high value set for the control system. These alarms are activated if an operator does not respond to the high level alarm or if there is an issue with the primary level measurement device. • Low-Low Level Alarm: An additional piece of safety equipment, which activates once the level of a unit operation has fallen below the low value set for the control system. These alarms are activated if an operator does not respond to the low level alarm or if there is an issue with the primary level measurement device. • Air Fail Open: When removing or blocking the pneumatic air from a control valve, the valve will open to its maximum. This is a forward acting valve. • Air Fail Closed: When removing or blocking the pneumatic air from a control valve, the valve will close completely. This is a reverse acting valve. 2.2 Describe each of the types of independent variables that are typically available for use in process control. • Control valve: Operates by changing the size of the opening of a choke point in a pipe which changes the quantity of fluid that can flow through the pipe for a given pressure drop. Conversely, the pressure drop incurred to force a given quantity of fluid through an opening can be adjusted. • Electrical supply interruption time: This independent variable works to open and close a contact on the electrical supply so that the equipment receives electric current for only a fraction of the time. For example, by varying the fraction of time a heater is energized, the energy input to the heater can be adjusted, which adjusts the surface temperature of the heating element • Electrical current resistance: A rheostat is used to vary the resistance to current flow in an electrical circuit. This in turn varies the electrical power available to power a motor or provide frictional heating to a heater element. For example, the
  • 7. Chapter 2 Page 3 flow of fluids can be controlled by varying the momentum introduced into the fluid by a pump or compressor. The momentum is varied by varying the electrical current supplied to the motor that drives the device which, in turn, varies the speed (rotation, piston travel speed, etc.) of the pump or compressor. The same concept applies to solids by changing the speed of conveyors or extruders. • Block valve open/close status: A block valve can be opened or closed on a fluid contained in a pipe. In this case, the quantity of fluid moving from one unit operation to another has only two states: full flow or no flow. This strategy is often employed for batch unit operations. 2.3 Describe a coupled control system and why such systems should be avoided whenever possible. • A coupled control system is one in which an independent variable has a direct and immediate effect on a dependent variable which is not part of its own control loop. When this happens, the control system is less stable, less responsive, and less capable of handling disturbances to the system, all which lead to a system which is more difficult to control. An example of this is trying to control liquid level in a drum by changing the pressure of the overhead gas stream, instead of changing the flow of the liquid bottoms. 2.4 For the following unit operations, a) identify the governing mass balance equations, b) determine the number of independent variables, c) determine the number of control variables, and d) design simple feedback control loops for each control variable. 2.4.1 A single effect evaporator a.

See drawing 2.7.3-A-001/1 2.8 Another example of the use of a feedback trim cascade control loop is in the operation of a Claus sulfur process. In this process, a feed gas containing H2S is partially combusted with air to yield a mixture of H2S, SO2, and S via the reactions: 2H2S + O2 ➔ 2H2O + 2S (2.2) 2H2S + 3O2 ➔ 2SO2 + 2H2O (2.3) The flue gas is cooled to condense out the sulfur. It is then sent through a series of reheaters, catalytic reactors, and condensers to produce additional sulfur via the reaction: 2H2S + SO2 ➔ 2H2O + 3S (2.4) The key to maximizing sulfur recovery is to have the correct H2S to oxygen ratio in the initial thermal oxidizer. Theoretically, this is a simple 2:1 ratio. However, due to variations in the concentration and flow rate of H2S in the process gas stream plus variations in the reaction efficiency of the thermal oxidizer and the three catalyst beds, the true optimum can only be found experimentally. As a result, the composition of either H2S or SO2 is measured in the final stream and this measurement is used in a feedback trim cascade controller to the inlet air ratio controller. Duplicate the drawing shown in Figure 2.28 and add a ratio with feedback trim control scheme to meet the operational objectives described above. • See Drawing 2.8-A-001/1 2.9 Consider the control scheme described on Figure 2.18 and the accompanying text. A more stable and responsive scheme uses the inlet cooling water flow and temperature of the outlet gas in a feedforward/feedback control as the slave in a cascade control scheme with an analyzer on the outlet stream as the master control loop. Modify Figure 2.18 to show this improved control scheme.
  • 14. Chapter 2 Page 10 • See Drawing 2.9-A-001/1 2.10 Consider the system shown in Figure 2.21. Many local regulatory agencies require that the opacity of the flue gas exiting the furnace or boiler stack be measured. Opacity is a measure of the quality of the combustion. If combustion is inefficient, then the flue gas will include soot and/or unburned fuel which will decrease the opacity of the exiting gas. If the opacity exceeds a certain point, action must be taken to increase the air to fuel ratio in order to insure that the discharge is within acceptable limits. Duplicate the scheme shown in Figure 2.21 and add a safety automation system control scheme that will take “last resort” action to add air into the burner if the opacity meter reaches its low-low alarm, analysis point. • See Drawing 2.10-A-001/1 2.11 Consider the neutralization system shown in Figure 2.14. This scheme can be improved by adding a cascade control loop that uses the outlet pH reading as the master dependent variable. Duplicate the scheme shown in Figure 2.14 and show how this improved scheme would be depicted. • See Drawing 2.11-A-001/1

  • 17. Imagine the difference between a preacher solemnly warning his hearers that the consequences of inattention may be everlasting torment, and a politician warning the Government that inattention may lead to a deficit! The truth is, that however terrible may be the earthly consequences of imprudence and of sin, they sink into complete insignificance before the menaces of the Church; nor is there, on the other hand, any worldly success that can be proposed as a motive comparable to the permanent happiness of Paradise. The good and the bad things of this world have alike the fatal defect, as subjects for eloquence, that they equally end in death; and as death is near to all of us, we see the end to both. The secular preacher is like a man who predicts a more or less comfortable journey, which comes to the same end in any case. A philosophic hearer is not very greatly elated by the promise of comforts so soon to be taken away, nor is he overwhelmed by the threat of evils that can but be temporary. Hence, in all matters belonging to this world only, the tone of quiet advice is the reasonable and appropriate tone, and it is that of the doctor and lawyer; but in matters of such tremendous import as eternal happiness and misery the utmost energy of eloquence can never be too great for the occasion; so that if a preacher can threaten like peals of thunder, and appal like flashes of lightning, he may use such terrible gifts without any disproportionate excess. On the other hand, if he has any charm of language, any brilliancy of imagination, there is nothing to prevent him from alluring his hearers to the paths of virtue by the most lavish and seductive promises. In short, his opportunities in both directions are of such a nature that exaggeration is impossible; and all his power, all his charm, are as free to do their utmost as an ocean wave in a tempest or the nightingale in the summer woods. I cannot quit the subject of clerical oratory without noticing one of its marked characteristics. The priest is not in a position of disinterested impartiality, like a man of science, who is ready to renounce any doctrine when he finds evidence against it. The priest is an advocate whose life-long pleading must be in favor of the
  • 18. Church as he finds her, and in opposition to her adversaries. To attack adversaries is therefore one of the recognized duties of his profession; and if he is not a man of uncommon fairness, if he has not an inborn love of justice which is rare in human nature, he will not only attack his adversaries but misrepresent them. There is even a worse danger than simple misrepresentation. A priest may possibly be a man of a coarse temper, and if he is so he will employ the weapons of outrage and vituperation, knowing that he can do so with impunity. One would imagine that these methods must inevitably repel and displease women, but there is a very peculiar reason why they seldom have this effect. A highly principled woman is usually so extremely eager to be on the side of what is right that suspension of judgment is most difficult for her. Any condemnation uttered by a person she is accustomed to trust has her approval on the instant. She cannot endure to wait until the crime is proved, but her feelings of indignation are at once aroused against the supposed criminal on the ground that there must be clear distinctions between right and wrong. The priest, for her, is the good man,—the man on the side of God and virtue; and those whom he condemns are the bad men,—the men on the side of the Devil and vice. This being so, he may deal with such men as roughly as he pleases. Nor have these men the faintest chance of setting themselves right in her opinion. She quietly closes the avenues of her mind against them; she declines to read their books; she will not listen to their arguments. Even if one of them is a near relation whose opinions inflict upon her what she calls “the deepest distress of mind,” she will positively prefer to go on suffering such distress until she dies, rather than allow him to remove it by a candid exposition of his views. She prefers the hostile misrepresentation that makes her miserable, to an authentic account of the matter that would relieve her anguish. Part III.—Association.
  • 19. The association of clergymen with ladies in works of charity affords continual opportunities for the exercise of clerical influence over women. A partnership in good works is set up which establishes interesting and cordial relations, and when the lady has accomplished some charitable purpose she remembers for long afterwards the clergyman without whose active assistance her project might have fallen to the ground. She sees in the clergyman a reflection of her own goodness, and she feels grateful to him for lending his masculine sense and larger experience to the realization of her ideas. There are other cases of a different nature in which the self-esteem of the lady is deeply gratified when she is selected by the clergyman as being more capable of devoted effort in a sacred cause than women of inferior piety and strength of mind. This kind of clerical selection is believed to be very influential in furthering clerical marriages. The lady is told that she will serve the highest of all causes by lending a willing ear to her admirer. Every reader will remember how thoroughly this idea is worked out in “Jane Eyre,” where St. John urges Jane to marry him on the plain ground that she would be a valuable fellow-worker with a missionary. Charlotte Brontë was, indeed, so strongly impressed with this aspect of clerical influence that she injured the best and strongest of her novels by an almost wearisome development of that episode. Clerical influence is immensely aided by the possession of leisure. Without underrating the self-devotion of hard-working clergymen (which is all the more honorable to them that they might take life more easily if they chose), we see a wide distinction, in point of industry, between the average clergyman and the average solicitor, for example. The clergyman has leisure to pay calls, to accept many invitations, and to talk in full detail about the interests that he has in common with his female friends. The solicitor is kept to his office by strictly professional work requiring very close application and allowing no liberty of mind. Much might be said about the effect of clerical leisure on clerical manners. Without leisure it is difficult to have such quiet and
  • 20. pleasant manners as the clergy generally have. Very busy men generally seem preoccupied with some idea of their own which is not what you are talking about, but a leisurely man will give hospitality to your thought. A busy man wants to get away, and fidgets you; a man of leisure dwells with you, for the time, completely. Ladies are exquisitely sensitive to these differences, and besides, they are generally themselves persons of leisure. Overworked people often confound leisure with indolence, which is a great mistake. Leisure is highly favorable to intelligence and good manners; indolence is stupid, from its dislike to mental effort, and ill-bred, from the habit of inattention. The feeling of women towards custom draws them strongly to the clergy, because a priesthood is the instinctive upholder of ancient customs and ceremonies, and steadily maintains external decorum. Women are naturally more attracted by custom than we are. A few men have an affectionate regard for the sanctities of usage, but most men only submit to them from an idea that they are generally helpful to the “maintenance of order;” and if women could be supposed absent from a nation for a time, it is probable that external observances of all kinds would be greatly relaxed. Women do not merely submit passively to custom; they uphold it actively and energetically, with a degree of faith in the perfect reasonableness of it which gives them great decision in its defence. It seems to them the ultimate reason from which there is no appeal. Now, in the life of every organized Church there is much to gratify this instinct, especially in those which have been long established. The recurrence of holy seasons, the customary repetition of certain forms of words, the observance at stated intervals of the same ceremonies, the adherence to certain prescribed decencies or splendors of dress, the reservation of sacred days on which labor is suspended, give to the religious life a charm of customariness which is deeply gratifying to good, order-loving women. It is said that every poet has something feminine in his nature; and it is certainly observable that poets, like women, are tenderly affected by the recurrence of holy seasons, and the observance of fixed religious
  • 21. rites. I will only allude to Keble’s “Christian Year,” because in this instance it might be objected that the poet was secondary to the Christian; but the reader will find instances of the same sentiment in Tennyson, as, for example, in the profoundly affecting allusions to the return of Christmas in “In Memoriam.” I could not name another occupation so closely and visibly bound up with custom as the clerical profession, but for the sake of contrast I may mention one or two others that are completely disconnected from it. The profession of painting is an example, and so is that of literature. An artist, a writer, has simply nothing whatever to do with custom, except as a private man. He may be an excellent and a famous workman without knowing Sunday from week-day or Easter from Lent. A man of science is equally unconnected with traditional observances. It may be a question whether a celibate or a married clergy has the greater influence over women. There are two sides to this question. The Church of Rome is, from the worldly point of view, the most astute body of men who have ever leagued themselves together in a corporation; and that Church has decided for celibacy, rejecting thereby all the advantages to be derived from rich marriages and good connections. In a celibate church the priest has a position of secure dignity and independence. It is known from the first that he will not marry, so there is no idle and damaging gossip about his supposed aspirations after fortune, or tender feelings towards beauty. Women can treat him with greater confidence than if he were a possible suitor, and then can confess to him, which is felt to be difficult with a married or a marriageable clergy. By being decidedly celibate the clergy avoid the possible loss of dignity which might result from allying themselves with families in a low social position. They are simply priests, and escape all other classification. A married man is, as it were, made responsible for the decent appearance, the good manners, and the proper conduct of three different sets of people. There is the family he springs from, there is his wife’s family, and, lastly, there is the family in his own house. Any one of these may drag a man down
  • 22. socially with almost irresistible force. The celibate priest is only affected by the family he springs from, and is generally at a distance from that. He escapes the invasion of his house by a wife’s relations, who might possibly be vulgar, and, above all, he escapes the permanent degradation of a coarse and ill-dressed family of his own. No doubt, from the Christian point of view, poverty is as honorable as wealth; but from the worldly point of view its visible imperfections are mean, despicable, and even ridiculous. In the early days of English Protestants the liberty to marry was ruinous to the social position of the clergy. They generally espoused servant-girls or “a lady’s maid whose character had been blown upon, and who was therefore forced to give up all hope of catching the steward.”[17] Queen Elizabeth issued “special orders that no clergyman should presume to marry a servant-girl without the consent of the master or mistress.” “One of the lessons most earnestly inculcated on every girl of honorable family was to give no encouragement to a lover in orders; and if any young lady forgot this precept she was almost as much disgraced as by an illicit amour.” The cause of these low marriages was simply poverty, and it is needless to add that they increased the evil. “As children multiplied and grew, the household of the priest became more and more beggarly. Holes appeared more and more plainly in the thatch of his parsonage and in his single cassock. His boys followed the plough, and his girls went out to service.” When clergymen can maintain appearances they gain one advantage from marriage which increases their influence with women. The clergyman’s wife is almost herself in holy orders, and his daughter often takes an equally keen interest in ecclesiastical matters. These “clergywomen,” as they have been called, are valuable allies, through whom much may be done that cannot be effected directly. This is the only advantage on the side of marriage, and it is but relative; for a celibate clergy has also its female allies who are scarcely less devoted; and in the Church of Rome there are great organized associations of women entirely under the control of ecclesiastics. Again, there is a lay element in a clergyman’s family
  • 23. which brings the world into his own house, to the detriment of its religious character. The sons of the clergy are often anything but clerical in feeling. They are often strongly laic, and even sceptical, by a natural reaction from ecclesiasticism. On the whole, therefore, it seems certain that an unmarried clergy more easily maintains both its own dignity and the distinction between itself and the laity. Auricular confession is so well known as a means of influencing women that I need scarcely do more than mention it; but there is one characteristic of it which is little understood by Protestants. They fancy (judging from Protestant feelings of antagonism) that confession must be felt as a tyranny. A Roman Catholic woman does not feel it to be an infliction that the Church imposes, but a relief that she affords. Women are not naturally silent sufferers. They like to talk about their anxieties and interests, especially to a patient and sympathetic listener of the other sex who will give them valuable advice. There is reason to believe that a good deal of informal confession is done by Protestant ladies; in the Church of Rome it is more systematic and leads to a formal absolution. The subject which the speaker has to talk about is that most interesting of all subjects, self. In any other place than a confessional to talk about self at any length is an error; in the confessional it is a virtue. The truth is that pious Roman Catholic women find happiness in the confessional and try the patience of the priests by minute accounts of trifling or imaginary sins. No doubt confession places an immense power in the hands of the Church, but at an incalculable cost of patience. It is not felt to weigh unfairly on the laity, because the priest who to-day has forgiven your faults will to-morrow kneel in penitence and ask forgiveness for his own. I do not see in the confessional so much an oppressive institution as a convenience for both parties. The woman gets what she wants,—an opportunity of talking confidentially about herself; and the priest gets what he wants,—an opportunity of learning the secrets of the household. Nothing has so powerfully awakened the jealousy of laymen as this institution of the confessional. The reasons have been so fully
  • 24. treated by Michelet and others, and are in fact so obvious, that I need not repeat them. The dislike for priests that is felt by many Continental laymen is increased by a cause that helps to win the confidence of women. “Observe,” the laymen say, “with what art the priest dresses so as to make women feel that he is without sex, in order that they may confess to him more willingly. He removes every trace of hair from his face, his dress is half feminine, he hides his legs in petticoats, his shoulders under a tippet, and in the higher ranks he wears jewelry and silk and lace. A woman would never confess to a man dressed as we are, so the wolf puts on sheep’s clothing.” Where confession is not the rule the layman’s jealousy is less acrid and pungent in its expression, but it often manifests itself in milder forms. The pen that so clearly delineated the Rev. Charles Honeyman was impelled by a layman’s natural and pardonable jealousy. A feeling of this kind is often strong in laymen of mature years. They will say to you in confidence, “Here is a man about the age of one of my sons, who knows no more concerning the mysteries of life and death than I do, who gets what he thinks he knows out of a book which is as accessible to me as it is to him, and yet who assumes a superiority over me which would only be justifiable if I were ignorant and he enlightened. He calls me one of his sheep. I am not a sheep relatively to him. I am at least his equal in knowledge, and greatly his superior in experience. Nobody but a parson would venture to compare me to an animal (such a stupid animal too!) and himself to that animal’s master. His one real and effective superiority is that he has all the women on his side.” You poor, doubting, hesitating layman, not half so convinced as the ladies of your family, who and what are you in the presence of a man who comes clothed with the authority of the Church? If you simply repeat what he says, you are a mere echo, a feeble repetition of a great original, like the copy of a famous picture. If you try to take refuge in philosophic indifference, in silent patience, you will be blamed for moral and religious inertia. If you venture to oppose and
  • 25. discuss, you will be the bad man against the good man, and as sure of condemnation as a murderer when the judge is putting on the black cap. There is no resource for you but one, and that does not offer a very cheering or hopeful prospect. By the exercise of angelic patience, and of all the other virtues that have been preached by good men from Socrates downwards, you may in twenty or thirty years acquire some credit for a sort of inferior goodness of your own,—a pinchbeck goodness, better than nothing, but not in any way comparable to the pure golden goodness of the priest; and when you come to die, the best that can be hoped for your disembodied soul will be mercy, clemency, indulgence; not approbation, welcome, or reward.
  • 26. I ESSAY XIV. WHY WE ARE APPARENTLY BECOMING LESS RELIGIOUS. T has happened to me on more than one occasion to have to examine papers left by ladies belonging to the last generation, who had lived in the manner most esteemed and respected by the general opinion of their time, and who might, without much risk of error, be taken for almost perfect models of English gentlewomen as they existed before the present scientific age. The papers left by these ladies consisted either of memoranda of their private thoughts, or of thoughts by others which seemed to have had an especial interest for them. I found that all these papers arranged themselves naturally and inevitably under two heads: either they concerned family interests and affections, or they were distinctly religious in character, like the religious meditations we find in books of devotion. There may be nothing extraordinary in this. Thousands of other ladies may have left religious memoranda; but consider what a preponderance of religious ideas is implied when written thoughts are entirely confined to them! The ladies in question lived in the first half of the nineteenth century, a period of great intellectual ferment, of the most important political and social changes, and of wonderful material progress; but they did not seem to have taken any real interest in these movements. The Bible and the commentaries of the clergy satisfied not only their spiritual but also their intellectual needs. They seem to have desired no knowledge of the universe, or of the probable origin and future of the human race, which the Bible did not supply. They seem to have cared for no example of human character and conduct other than the scriptural examples.
  • 27. This restfulness in Biblical history and philosophy, this substitution of the Bible for the world as a subject of study and contemplation, this absence of desire to penetrate the secrets of the world itself, this want of aspiration after any ideal more recent than the earlier ages of Christianity, permitted a much more constant and uninterrupted dwelling with what are considered to be religious ideas than is possible to any active and inquiring mind of the present day. Let it be supposed, for example, that a person to whom the Bible was everything desired information about the origin of the globe, and of life upon it; he would refer to the Book of Genesis as the only authority, and this reference would have the character of a religious act, and he would get credit for piety on account of it; whilst a modern scientific student would refer to some great modern paleontologist, and his reference would not have the character of a religious act, nor bring him any credit for piety; yet the prompting curiosity, the desire to know about the remote past, would be exactly the same in both cases. And I think it may be easily shown that if the modern scientific student appears to be less religious than others think he ought to be, it is often because he possesses and uses more abundant sources of information than those which were accessible to the ancient Jews. It is not his fault if knowledge has increased; he cannot be blamed if he goes where information is most copious and most exact; yet his preference for such information gives an unsanctified aspect to his studies. The study of the most ancient knowledge wears a religious aspect, but the study of modern knowledge appears to be non-religious. Again, when we come to the cultivation of the idealizing faculties, of the faculties which do not seek information merely, but some kind of perfection, we find that the very complexity of modern life, and the diversity of the ideal pleasures and perfections that we modern men desire, have a constant tendency to take us outside of strictly religious ideals. As long as the writings which are held to be sacred supply all that our idealizing faculties need, so long will our imaginative powers exercise themselves in what is considered to be a religious manner, and we shall get credit for piety; but when our
  • 28. minds imagine what the sacred writers could not or did not conceive, and when we seek help for our imaginative faculty in profane writers, we appear to be less religious. So it is with the desire to study and imitate high examples of conduct and character. There is no nobler or more fruitful instinct in man than a desire like this, which is possible only to those who are at once humble and aspiring. An ancient Jew who had this noble instinct could satisfy it by reading the sacred books of the Hebrews, and so his aspiration appeared to be wholly religious. It is not so with an active-minded young Englishman of the present day. He cannot find the most inspiriting models amongst the ancient Hebrews, for the reason that their life was altogether so much simpler and more primitive than ours. They had nothing that can seriously be called science; they had not any organized industry; they had little art, and hardly any secular literature, so that in these directions they offer us no examples to follow. Our great inspiriting examples in these directions are to be found either in the Renaissance or in recent times, and therefore in profane biography. From this it follows that an active modern mind seems to study and follow non-religious examples, and so to differ widely, and for the worse, from the simpler minds of old time, who were satisfied with the examples they found in their Bibles. This appearance is misleading; it is merely on the surface; for if we go deeper and do not let ourselves be deceived by the words “sacred” and “profane,” we shall find that when a simple mind chooses a model from a primitive people, and a cultivated one chooses a model from an advanced people, and from the most advanced class in it, they are both really doing the same thing, namely, seeking ideal help of the kind which is best for each. Both of them are pursuing the same object,—a mental discipline and elevation which may be comprised under the general term virtue; the only difference being that one is studying examples of virtue in the history of the ancient Jews, whilst the other finds examples of virtue more to his own special purpose in the lives of energetic Englishmen, Frenchmen, or Germans.
  • 29. A hundred such examples might be mentioned, for every occupation worth following has its own saints and heroes; but I will confine myself to two. The first shall be a French gentleman of the eighteenth century, to whom life offered in the richest profusion everything that can tempt a man to what is considered an excusable and even a respectable form of idleness. He had an independent fortune, excellent health, a good social position, and easy access to the most lively, the most entertaining, the most amiable society that ever was, namely, that of the intelligent French nobility before the Revolution. There is no merit in renouncing what we do not enjoy; but he enjoyed all pleasant things, and yet renounced them for a higher and a harder life. At the age of thirty-two he retired to the country, made a rule of early rising and kept it, sallied forth from his house every morning at five, went and shut himself up in an old tower with a piece of bread and a glass of water for his breakfast, worked altogether eleven or twelve hours a day in two sittings, and went to bed at nine. This for eight months in the year, regularly, the remaining four being employed in scientific and administrative work at the Jardin des Plantes. He went on working in this way for forty years, and in the whole course of that time never let pass an ill- considered page or an ill-constructed sentence, but always did his best, and tried to make himself able to do better. Such was the great life of Buffon; and in our own time another great life has come to its close, inferior to that of Buffon only in this, that as it did not begin in luxury, the first renunciation was not so difficult to make. Yet, however austere his beginnings, it is not a light or easy thing for a man to become the greatest intellectual worker of his time, so that one of his days (including eight hours of steady nocturnal labor) was equivalent to two or more of our days. No man of his time in Europe had so vast a knowledge of literature and science in combination; yet this knowledge was accompanied by perfect modesty and by a complete indifference to vulgar distinctions and vain successes. For many years he was the butt of coarse and malignant misrepresentation on the part of enemies who easily made him odious to a shallow society; but he bore it with perfect
  • 30. dignity, and retained unimpaired the tolerance and charity of his nature. His way of living was plain and frugal; he even contented himself with narrow dwellings, though the want of space must have occasioned frequent inconvenience to a man of his pursuits. He scrupulously fulfilled his domestic duties, and made use of his medical education in ministering gratuitously to the poor. Such was his courage that when already advanced in life he undertook a gigantic task, requiring twenty years of incessant labor; and such were his industry and perseverance that he brought it to a splendidly successful issue. At length, after a long life of duty and patience, after bearing calumny and ridicule, he was called to endure another kind of suffering,—that of incessant physical pain. This he bore with perfect fortitude, retaining to the last his mental serenity, his interest in learning, and a high-minded patriotic thoughtfulness for his country and its future, finding means in the midst of suffering to dictate long letters to his fellow-citizens on political subjects, which, in their calm wisdom, stood in the strongest possible contrast to the violent party writing of the hour. Such was the great life of Littré; and now consider whether he who studies lives like these, and wins virtue from their austere example, does not occupy his thoughts with what would have been considered religious aspirations, if these two men, instead of being Frenchmen of the eighteenth and nineteenth centuries, had happened to be ancient Jews. If it had been possible for so primitive a nation as the Jewish to produce men of such steady industry and so large a culture, we should have read the story of their lives in the Jewish sacred books, and then it would have been a part of the popular religion to study them, whereas now the study of such biography is held to be non-religious, if not (at least in the case of Littré) positively irreligious. Yet surely when we think of the virtues which made these lives so fruitful, our minds are occupied in a kind of religious thought; for are we not thinking of temperance, self- discipline, diligence, perseverance, patience, charity, courage, hope? Were not these men distinguished by their aspiration after higher perfection, by a constant desire to use their talents well, and by a
  • 31. vigilant care in the employment of their time? And are not these virtues and these aspirations held to be parts of a civilized man’s religion, and the best parts? The necessity for an intellectual expansion beyond the limits of the Bible was felt very strongly at the time of the Renaissance, and found ample satisfaction in the study of the Greek and Latin classics. There are many reasons why women appear to be more religious than men; and one of them is because women study only one collection of ancient writings, whilst men have been accustomed to study three; consequently that which women study (if such a word is applicable to devotional, uncritical reading) occupies their minds far more exclusively than it occupies the mind of a classical scholar. But, though the intellectual energies of men were for a time satisfied with classical literature, they came at length to look outside of that as their fathers had looked outside of the Bible. Classical literature was itself a kind of religion, having its own sacred books; and it had also its heretics,—the students of nature,—who found nature more interesting than the opinions of the Greeks and Romans. Then came the second great expansion of the human mind, in the midst of which we ourselves are living. The Renaissance opened for it a world of mental activity which had the inappreciable intellectual advantage of lying well outside of the popular beliefs and ideas, so that cultivated men found in it an escape from the pressure of the uneducated; but the new scientific expansion offers us a region governed by laws of a kind peculiar to itself, which protect those who conform to them against every assailant. It is a region in which authority is unknown, for, however illustrious any great man may appear in it, every statement that he makes is subject to verification. Here the knowledge of ancient writers is continually superseded by the better and more accurate knowledge of their successors; so that whereas in religion and learning the most ancient writings are the most esteemed, in science it is often the most recent, and even these have no authority which may not be called in question freely by any student. The new scientific culture is thus encouraging a habit of mind different from old habits, and which in our time has
  • 32. caused such a degree of separation that the most important and the most interesting of all topics are those upon which we scarcely dare to venture for fear of being misunderstood. If I had to condense in a short space the various reasons why we are apparently becoming less religious, I should say that it is because knowledge and feeling, embodied or expressed in the sciences and arts, are now too fully and too variously developed to remain within the limits of what is considered sacred knowledge or religious emotion. It was possible for them to remain well within those limits in ancient times, and it is still possible for a mind of very limited activity and range to dwell almost entirely in what was known or felt at the time of Christ; but this is not possible for an energetic and inquiring mind, and the consequence is that the energetic mind will seem to the other, by contrast, to be negligent of holy things, and too much occupied with purely secular interests and concerns. A great misunderstanding arises from this, which has often had a lamentable effect on intercourse between relations and friends. Pious ladies, to whom theological writings appear to contain almost everything that it is desirable to know, often look with secret misgiving or suspicion on young men of vigorous intellect who cannot rest satisfied with the old knowledge, and what such ladies vaguely hear of the speculations of the famous scientific leaders inspires them with profound alarm. They think that we are becoming less religious because theological writings do not occupy the same space in our time and thoughts as they do in theirs; whereas, if such a matter could be put to any kind of positive test, it would probably be found that we know more, even of their own theology, than they do, and that, instead of being indifferent to the great problems of the universe, we have given to such problems an amount of careful thought far surpassing, in mental effort, their own simple acquiescence. The opinions of a thoughtful and studious man in the present day have never been lightly come by; and if he is supposed to be less religious than his father or his grandfather it may be that his religion is different from theirs, without being either less earnest or less enlightened. There is, however, one point of immense
  • 33. importance on which I believe that we really are becoming less religious, indeed on that point we seem to be rapidly abandoning the religious principle altogether; but the subject is of too much consequence to be treated at the end of an Essay.
  • 34. T ESSAY XV. HOW WE ARE REALLY BECOMING LESS RELIGIOUS. HE reader may remember how, after the long and unsuccessful siege of Syracuse, the Athenian general Nikias, seeing his discouraged troops ill with the fever from the marshes, determined to raise the siege; and that, when his soldiers were preparing to retreat, and striking their tents for the march, there occurred an eclipse of the moon. Nikias, in his anxiety to know what the gods meant by this with reference to him and his army, at once consulted a soothsayer, who told him that he would incur the Divine anger if he did not remain where he was for three times nine days. He remained, doing nothing, allowing his troops to perish and his ships to be shut up by a line of the enemy’s vessels chained together across the entrance of the port. At length the three times nine days came to an end, and what was left of the Athenian army had to get out of a situation that had become infinitely more difficult during its inaction. The ships tried to get out in vain; the army was able to retreat by land, but only to be harassed by the enemy, and finally placed in such distress that it was compelled to surrender. Most of the remnant died miserably in the old quarries of Syracuse. The conduct of Nikias throughout these events was in the highest degree religious. He was fully convinced that the gods concerned themselves about him and his doings, that they were watching over him, and that the eclipse was a communication from them not to be neglected without a breach of religious duty. He, therefore, in the spirit of the most perfect religious faith, which we are compelled to admire for its sincerity and thoroughness, shut his eyes resolutely to all the visible facts of a situation more disastrous every day, and
  • 35. attended only to the invisible action of the invisible gods, of which nothing could be really known by him. For twenty-seven days he went on quietly sacrificing his soldiers to his faith, and only moved at last when he believed that the gods allowed it. In contrast with this, let us ask what we think of an eclipse ourselves, and how far any religious emotion, determinant of action or of inaction, is connected with the phenomenon in our experience. We know, in the first place, that eclipses belong to the natural order, and we do not feel either grateful to the supernatural powers, or ungrateful, with regard to them. Even the idea that eclipses demonstrate the power of God is hardly likely to occur to us, for we constantly see terrestrial objects eclipsed by cast shadows; and the mere falling of a shadow is to us only the natural interruption of light by the intervention of any opaque object. In the true theory of eclipses there is absolutely no ground whatever for religious emotion, and accordingly the phenomenon is now entirely disconnected from religious ideas. The consequence is that where the Athenian general had a strong motive for religious emotion, a motive so strong that he sacrificed his army to the supposed will of Heaven, a modern general in the same situation would feel no emotion and make no sacrifice. If this process stopped at eclipses the result would be of little importance, as eclipses of the celestial bodies are not frequently visible, and to lose the opportunity of emotion which they present is not a very sensible loss. But so far is the process from stopping at eclipses, that exactly the same process is going on with regard to thousands of other phenomena which are one by one, yet with increasing rapidity, ceasing to be regarded as special manifestations of Divine will, and beginning to be regarded as a part of that order of nature with which, to quote Professor Huxley’s significant language, “nothing interferes.” Every one of these transferrences from supernatural government to natural order deprives the religious sentiment of one special cause or motive for its own peculiar kind of emotion, so that we are becoming less and less accustomed to such
  • 36. emotion (as the opportunities for it become less frequent), and more and more accustomed to accept events and phenomena of all kinds as in that order of nature “with which nothing interferes.” This single mental conception of the unfailing regularity of nature is doing more in our time to affect the religious condition of thoughtful people than could be effected by many less comprehensive conceptions. It has often been said, not untruly, that merely negative arguments have little permanent influence over the opinions of men, and that institutions which have been temporarily overthrown by negation will shortly be set up again, and flourish in their old vigor, unless something positive can be found to supply their place. But here is a doctrine of a most positive kind. “The order of nature is invariably according to regular sequences.” It is a doctrine which cannot be proved, for we cannot follow all the changes which have ever taken place in the universe; but, although incapable of demonstration, it may be accepted until something happens to disprove it; and it is accepted, with the most absolute faith, by a constantly increasing number of adherents. To show how this doctrine acts in diminishing religious emotion by taking away the opportunity for it, let me narrate an incident which really occurred on a French line of railway in the winter of 1882. The line, on which I had travelled a few days before, passes between a river and a hill. The river has a rocky bed and is torrential in winter; the hill is densely covered with a pine forest coming down to the side of the line. The year 1882 had been the rainiest known in France for two centuries, and the roots of the trees on the edge of this pine forest had been much loosened by the rain. In consequence of this, two large pine-trees fell across the railway early one morning, and soon afterwards a train approached the spot by the dim light of early dawn. There was a curve just before the engine reached the trees, and it had come rapidly for several miles down a decline. The driver reversed his steam, the engine and tender leaped over the trees, and then went over the embankment
  • 37. to a place within six feet of the rapid river. The carriages remained on the line, but were much broken. Nobody was killed; nobody was seriously injured. The remarkable escape of the passengers was accounted for as follows by the religious people in the neighborhood. There happened to be a priest in the train, and at the time when the shock took place he made what is called “a pious ejaculation.” This, it was said, had saved the lives of the passengers. In the ages of faith this explanation would have been received without question; but the notion of natural sequences—Professor Huxley’s “order with which nothing interferes”—had obtained such firm hold on the minds of the townsmen generally that they said the priest was trying to make ecclesiastical capital out of an occurrence easily explicable by natural causes. They saw nothing supernatural either in the production of the accident or its comparative harmlessness. The trickling of much water had denuded the roots of the trees, which fell because they could not stand with insufficient roothold; the lives of the passengers were saved because they did not happen to be in the most shattered carriage; and the men on the engine escaped because they fell on soft ground, made softer still by the rain. It was probable, too, they said, that if any beneficent supernatural interference had taken place it would have maintained the trees in an erect position, by preventive miracle, and so spared the slight injuries which really were inflicted, and which, though treated very lightly by others because there were neither deaths nor amputations, still caused suffering to those who had to bear them. Now if we go a little farther into the effects of this accident on the minds of the people who shared in it, or whose friends had been imperilled by it, we shall see very plainly the effect of the modern belief in the regularity of natural sequences. Those who believed in supernatural intervention would offer thanksgivings when they got home, and probably go through some special religious thanksgiving services for many days afterwards; those who believed in the regularity of natural sequences would simply feel glad to have escaped, without any especial sense of gratitude to supernatural powers. So much for the effect as far as thanksgiving is concerned;
  • 38. but there is another side of the matter at least equally important from the religious point of view,—that of prayer. The believers in supernatural interference would probably, in all their future railway journeys, pray to be supernaturally protected in case of accident, as they had been in 1882; but the believers in the regularity of natural sequences would only hope that no trees had fallen across the line, and feel more than usually anxious after long seasons of rainy weather. Can there be a doubt that the priest’s opinion, that he had won safety by a pious ejaculation, was highly favorable to his religious activity afterwards, whilst the opinion of the believers in “the natural order with which nothing interferes” was unfavorable both to prayer and thanksgiving in connection with railway travelling? Examples of this kind might easily be multiplied, for there is hardly any enterprise that men undertake, however apparently unimportant, which cannot be regarded both from the points of view of naturalism and supernaturalism; and in every case the naturalist manner of regarding the enterprise leads men to study the probable influence of natural causes, whilst the supernaturalist opinion leads them to propitiate supernatural powers. Now, although some new sense may come to be attached to the word “religion” in future ages, so that it may come to mean scientific thoroughness, intellectual ingenuousness, or some other virtue that may be possessed by a pure naturalist, the word has always been understood, down to the present time, to imply a constant dependence upon the supernatural; and when I say that we are becoming less religious, I mean that from our increasing tendency to refer everything to natural causes the notion of the supernatural is much less frequently present in our minds than it was in the minds of our forefathers. Even the clergy themselves seem to be following the laity towards the belief in natural law, at least so far as matter is concerned. The Bishop of Melbourne, in 1882, declined to order prayers for rain, and gave his reason honestly, which was that material phenomena were under the control of natural law, and would not be changed in answer to prayer. The Bishop added that
  • 39. prayer should be confined to spiritual blessings. Without disputing the soundness of this opinion, we cannot help perceiving that if it were generally received it would put an end to one half of the religious activity of the human race; for half the prayers and half the thanksgivings addressed to the supernatural powers are for material benefits only. It is possible that, in the future, religious people will cease to pray for health, but take practical precautions to preserve it; that they will cease to pray for prosperity, but study the natural laws which govern the wealth of nations; that they will no longer pray for the national fleets and armies, but see that they are well supplied and intelligently commanded. All this and much more is possible; but when it comes to pass the world will be less religious than it was when men believed that every pestilence, every famine, every defeat, was a chastisement specially, directly, and intentionally inflicted by an angry Deity. Even now, what an immense step has been made in this direction! In the fearful description of the pestilence at Florence, given with so much detail by Boccaccio, he speaks of “l’ira di Dio a punire la iniquità degli uomini con quella pestilenza;” and he specially implies that those who sought to avoid the plague by going to healthier places in the country deceived themselves in supposing that the wrath of God would not follow them whithersoever they went. That is the old belief expressing itself in prayers and humiliations. It is still recognized officially. If the plague could occur in a town on the whole so well cared for as modern London, the language of Boccaccio would still be used in the official public prayers; but the active-minded practical citizens would be thinking how to destroy the germs, how to purify air and water. An instance of this divergence occurred after the Egyptian war of 1882. The Archbishop of York, after the battle of Tel-el-Kebir, ordered thanksgivings to be offered in the churches, on the ground that God was in Sir Garnet Wolseley’s camp and fought with him against the Egyptians, which was a survival of the antique idea that national deities fought with the national armies. On this a Member of Parliament, Mr. George Palmer, said to his constituents in a public meeting at Reading, “At the same time I cannot agree with the prayers that have been made in churches. Though I respect the
