This document discusses the ultimate purpose and happiness of mankind. It states that while riches, honors, glory and other worldly pleasures may bring partial happiness, ultimate happiness is found only in God. As humans live on earth, they must work to attain perfection and union with God, their ultimate happiness. Original sin wounded human nature, so people must perfect themselves through virtues like wisdom, justice and temperance in order to possess God. The chief end of man is to glorify and enjoy God for eternity, though individuals will face judgment after death and receive eternal beatitude in heaven or damnation in hell.
