“No one in this world, so far as I know—and I have searched the record for years, and employed agents to help me—has ever lost money by underestimating the intelligence of the great masses of the plain people.”

“A philosopher is a blind man in a dark room looking for a black cat that isn't there. A theologian is the man who finds it.”

“One of the most irrational of all the conventions of modern society is the one to the effect that religious opinions should be respected. …[This] convention protects them, and so they proceed with their blather unwhipped and almost unmolested, to the great damage of common sense and common decency. that they should have this immunity is an outrage. There is nothing in religious ideas, as a class, to lift them above other ideas. On the contrary, they are always dubious and often quite silly. Nor is there any visible intellectual dignity in theologians. Few of them know anything that is worth knowing, and not many of them are even honest.”

“I have often misunderstood men grossly, and I have misrepresented them when I understood them, sacrificing sense to make a phrase. Here, of course, is where even the most conscientious critic often goes aground; he is apt to be an artist before he is a scientist, and the impulse to create something passionately is stronger in him than the impulse to state something accurately.”

“Moral certainty is always a sign of cultural inferiority. 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.”

“Self-respect--the secure feeling that no one, as yet, is suspicious.”

“Every great wave of popular passion that rolls up on the prairies is dashed to spray when it strikes the hard rocks of Manhattan.”

“New York: A third-rate Babylon.”

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

“A poet more than thirty years old is simply an overgrown child.”

“The notion that a radical is one who hates his country is naïve and usually idiotic. He is, more likely, one who likes his country more than the rest of us, and is thus more disturbed than the rest of us when he sees it debauched. He is not a bad citizen turning to crime; he is a good citizen driven to despair.”
