Faith without evidence is, properly, not faith, but prejudice or presumption; faith beyond evidence is superstition, and faith contrary to evidence is either insanity or willful perversity of mind.

In individuals, insanity is rare; but in groups, parties, nations, and epochs it is the rule.

Unwelcome are the loiterer, who makes appointments he never keeps; the consulter, who asks advice he never follows; the boaster, who seeks for praise he does not merit; the complainer, who whines only to be pitied; the talker, who talks only because he loves to talk always; the profane and obscene jester, whose words defile; the drunkard, whose insanity has tot the better of his reason; and the tobacco-chewer and smoker, who poisons the atmosphere and nauseates others.

From a social standpoint, dependence denotes a power rather than a weakness; it involves interdependence. There is always a danger that increased personal independence will decrease the social capacity of an individual. In making him more self-reliant, it may make him more self-sufficient; it may lead to aloofness and indifference. It often makes an individual so insensitive in his relations to others as to develop an illusion of being really able to stand and act alone — an unnamed form of insanity which is responsible for a large part of the remedial suffering of the world.

Sophisticated thinking may enable man to feign his being sufficient to himself. Yet the way to insanity is paved with such illusions. The feeling of futility that comes with the sense of being useless, of not being needed in the world, is the most common cause of psychoneurosis. The only way to avoid despair is to be a need rather than an end. Happiness, in fact, may be defined as the certainty of being needed. But who is in need of man?

But he who knows what insanity is, is sane; whereas insanity can no more be sensible of its own existence, than blindness can see itself.

Between these two unique and symmetrical events, something happens whose ambiguity has left the historians of medicine at a loss: blind repression in an absolutist regime, according to some; but according to others, the gradual discovery by science and philanthropy of madness in its positive truth. As a matter of fact, beneath these reversible meanings, a structure is forming which does not resolve the ambiguity but determines it. It is this structure which accounts for the transition from the medieval and humanist experience of madness to our own experience, which confines insanity within mental illness. In the Middle Ages and until the Renaissance, man's dispute with madness was a dramatic debate in which he confronted the secret powers of the world; the experience of madness was clouded by images of the Fall and the Will of God, of the Beast and the Metamorphosis, and of all the marvelous secrets of Knowledge. In our era, the experience of madness remains silent in the composure of a knowledge which, knowing too much about madness, forgets it. But from one of these experiences to the other, the shift has been made by a world without images, without positive character, in a kind of silent transparency which reveals— as mute institution, act without commentary, immediate knowledge—a great motionless structure; this structure is one of neither drama nor knowledge; it is the point where history is immobilized in the tragic category which both establishes and impugns it.

Five hundred years of ecological mayhem and social tyranny is a relatively short time for humanity to have learned to understand its self-created patterns of systematic pillage. The insanity of human destructiveness may be matched by an older grace and intelligence that is fastening us together in ways we have never before seen or imagined... We live in community, not alone, and any sense of separateness that we harbor is illusion.

People who think they can control their negative emotions and manifest them when they want to, simply deceive themselves. Negative emotions depend on identification; if identification is destroyed in some particular case, they disappear. The strangest and most fantastic fact about negative emotions is that people actually worship them. I think that, for an ordinary mechanical man, the most difficult thing to realize is that his own and other people's negative emotions, have no value whatever and do not contain anything noble, anything beautiful or anything strong. In reality negative emotions contain nothing but weakness and very often the beginning of hysteria, insanity or crime. The only good thing about them is that, being quite useless and artificially created by imagination and identification, they can be destroyed without any loss. And this is the only chance of escape that man has. Philosophy is based on speculation, on logic, on thought, on the synthesis of what we know and on the analysis of what we do not know. Philosophy must include within its confines the whole content of science, religion and art. But where can such a philosophy be found? All that we know in our times by the name of philosophy is not philosophy, but merely critical literature or the expression of personal opinions, mainly with the aim of overthrowing and destroying other personal opinions. Or, which is still worse, philosophy is nothing but self-satisfied dialectic surrounding itself with an impenetrable barrier of terminology unintelligible to the uninitiated and solving for itself all the problems of the universe without any possibility of proving these explanations or making them intelligible to ordinary mortals.

The definition of insanity is doing the same thing over again and expecting a different outcome.

If there be one thing on earth which is truly admirable, it is to see God's wisdom blessing an inferiority of natural powers, where they have been honestly, truly, and zealously cultivated.

One’s age should be tranquil, as one’s childhood should be playful; hard work at either extremity of human existence seems to me out of place: the morning and the evening should be alike cool and peaceful; at mid-day the sun may burn, and men may labor under it.

Do a lot of reading. [On how to determine the value of a business]

As to the past, I would not mind retrieving from various corners of space-time certain lost comforts, such as baggy trousers and long, deep bathtubs.

If ever a human being got his work expressed completely, it was Shakespeare. If ever a mind was incandescent, unimpeded... it was Shakespeare's mind.

Armed neutrality, it now appears, is impracticable.

A child born to a black mother in a state like Mississippi . . . has the same rights as a white baby born to the wealthiest person in the United States. It's not true, but I challenge anyone to say it is not a goal worth working for.

LSD is a psychedelic drug which occasionally causes psychotic behavior in people who have NOT taken it.

The greatness of action includes immoral as well as moral greatness--Cortes and Napoleon, as well as Luther and Washington.
