“Immortality is the condition of a dead man who doesn’t believe he is dead.”

“The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on - I am not too sure.”

“Any man who afflicts the human race with ideas must be prepared to see them misunderstood. ”

“Every decent man is ashamed of the government he lives under.”

“Nevertheless, it is the Christian theory that it is only a regard for this Being -- partly a trembling fear and partly a kind of conciliation represented to be love -- that keeps the human race from roaring downhill to villainy and disaster. Nor are theologians daunted by the obvious fact that many open and even ribald skeptics are not going that way, but, on the contrary, show a considerably higher degree of virtue than the Christian average. Their answer ... is that the moral sense of every such blameless candidate for Hell 'is a kind of parasitic growth upon the otherworldliness of the society in which he lives.' ... Even men who should know better indulge in this confusion between the religious impulse and common decency. ... But this is surely going beyond the plain facts. A man may be truly religious without imagining God as good at all, and he may be good without believing that there is any moral order in the universe or even that God exists. Religion does not necessarily make men better citizens, whether of their neighborhoods or of the world.”

“Men become civilized, not in proportion to their willingness to believe, but in proportion to their readiness to doubt.”

“If the average man is made in God's image, then such a man as Beethoven or Aristotle is plainly superior to God....”
