“A man who has throttled a bad impulse has at least some consolation in his agonies, but a man who has throttled a good one is in a bad way indeed.”

“The Sun editorial on Roosevelt this morning begins: "Franklin D. Roosevelt was a great man."… The argument, in brief, is that all his skullduggeries and imbecilities were wiped out when "he took an inert and profoundly isolationist people and brought them to support a necessary war on a scale never before imagined." In other words, his greatest fraud was his greatest glory, and his sufficient excuse for all his other frauds. It seems to me to be very likely that Roosevelt will take a high place in American popular history -- maybe even alongside Washington and Lincoln… He had every quality that morons esteem in their heros. It will be to the interest of all his heirs and assigns to whoop him up, and they will probably succeed in swamping his critics.”

“Government is actually the worst failure of civilized man. There has never been a really good one, and even those that are most tolerable are arbitrary, cruel, grasping and unintelligent. Indeed, it would not be far wrong to describe the best as the common enemy of all decent citizens. But there will be small hope of gaining adherents to this idea so long as government is thought of as an independent and somehow super-human organism, with powers, rights, and privileges transcending those of any other human aggregation.”

“To a clergyman lying under a vow of chastity any act of sex is immoral, but his abhorrence of it naturally increases in proportion as it looks safe and is correspondingly tempting. As a prudent man, he is not much disturbed by incitations which carry their obvious and certain penalties; what shakes him is the enticement bare of any probable secular retribution. Ergo, the worst and damndest indulgence is that which goes unwhipped. So he teaches that it is no sin for a woman to bear a child to a drunken and worthless husband, even though she may believe with sound reason that it will be diseased and miserable all its life, but if she resorts to any mechanical or chemical device, however harmless, to prevent its birth, she is doomed by his penology to roast in Hell forever, along with the assassin of orphans and the scoundrel who forgets his Easter duty.”

“The chief difference between free capitalism and State socialism seems to be this: that under the former a man pursues his own advantage openly, frankly and honestly, whereas under the latter he does so hypocritically and under false pretenses.”

“The State is not force alone. It depends upon the credulity of man quite as much as upon his docility. Its aim is not merely to make him obey, but also to make him want to obey.”

“My guess is that well over eighty per cent of the human race goes through life without ever having a single original thought. That is to say, they never think anything that has not been thought before, and by thousands.
A society made up of individuals who were all capable of original thought would probably be unendurable. The pressure of ideas would simply drive it frantic. The normal human society is very little troubled by them. Whenever a new one appears the average man displays signs of dismay and resentment. The only way he can take in such a new idea is by translating it crudely into terms of more familiar ideas. That translation is one of the chief functions of politicians, not to mention journalists. They devote themselves largely to debasing the ideas launched by their betters. This debasement is intellectually reprehensible, but probably necessary to carry on the business of the world.”

“To be in love is merely to be in a state of perpetual anesthesia — to mistake an ordinary young man for a Greek god or an ordinary young woman for a goddess.”

“Democratic man can understand the aims and aspirations of capitalism; they are, greatly magnified, simply his own aims and aspirations.”

1920s, Notes on Democracy (1926)

“To be happy one must be (a) well fed, unhounded by sordid cares, at ease in Zion, (b) full of a comfortable feeling of superiority to the masses of one's fellow men, and (c) delicately and unceasingly amused according to one's taste. It is my contention that, if this definition be accepted, there is no country in the world wherein a man constituted as I am — a man of my peculiar weakness, vanities, appetites, and aversions — can be so happy as he can be in the United States.”

On Being An American (1922)
1920s

“I believe that liberty is the only genuinely valuable thing that men have invented, at least in the field of government, in a thousand years. I believe that it is better to be free than to be not free, even when the former is dangerous and the latter safe. I believe that the finest qualities of man can flourish only in free air – that progress made under the shadow of the policeman’s club is false progress, and of no permanent value. I believe that any man who takes the liberty of another into his keeping is bound to become a tyrant, and that any man who yields up his liberty, in however slight the measure, is bound to become a slave.”

"Why Liberty?”, in the Chicago Tribune (30 January 1927)

“I believe that religion, generally speaking, has been a curse to mankind — that its modest and greatly overestimated services on the ethical side have been more than overcome by the damage it has done to clear and honest thinking.
I believe that no discovery of fact, however trivial, can be wholly useless to the race, and that no trumpeting of falsehood, however virtuous in intent, can be anything but vicious.
I believe that all government is evil, in that all government must necessarily make war upon liberty; and the democratic form is as bad as any of the other forms.
I believe that the evidence for immortality is no better than the evidence of witches, and deserves no more respect.
I believe in the complete freedom of thought and speech — alike for the humblest man and the mightiest, and in the utmost freedom of conduct that is consistent with living in organized society.
I believe in the capacity of man to conquer his world, and to find out what it is made of, and how it is run.
I believe in the reality of progress.
I —But the whole thing, after all, may be put very simply. I believe that it is better to tell the truth than to lie. I believe that it is better to be free than to be a slave. And I believe that it is better to know than be ignorant.”
