This prologue introduces the book which analyzes Senator Joseph McCarthy and his opponents during the McCarthy era controversies. It summarizes that the authors have chosen to investigate McCarthy's actual record rather than accept prevailing judgments, in violation of current intellectual etiquette. It contends the true difference between McCarthy and his opponents is that he took the responsibility of intellectual choices seriously, while they insisted intellectuals bore no responsibility. The prologue argues the scandal was McCarthy's opponents invoking a special dispensation from intellectual responsibility and a "fool's franchise" to avoid being taken seriously for their ideas and commitments.
