The belly is an ungrateful wretch, it never remembers past favors, it always wants more tomorrow.

In the state of nature, wrong-doing is impossible ; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so ; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power.

Heroic love is the property of those superior natures who are called insane not because they do not know, but because they over-know.

Psychoanalysis is essentially a theory of unconscious strivings, of resistance, of falsification of reality according to one's subjective needs and expectations.

Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so. And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.

I am thus one of the very few examples, in this country, of one who has, not thrown off religious belief, but never had it...

Wit is cultured insolence.

Kant [...] stated that he had "found it necessary to deny knowledge [...] to make room for faith," but all he had "denied" was knowledge of things that are unknowable, and he had not made room for faith but for thought.

History proves nothing because it contains everything.

In the upper, rich, more educated classes of European society doubt arose as to the truth of that understanding of life which was expressed by Church Christianity. When, after the Crusades and the maximum development of papal power and its abuses, people of the rich classes became acquainted with the wisdom of the classics and saw, on the one hand, the reasonable lucidity of the teachings of the ancient sages, and on the other hand, the incompatibility of the Church doctrine with the teaching of Christ, they found it impossible to continue to believe the Church teaching.

To read is to let someone else work for you - the most delicate form of exploitation.

It is vain to expect virtue from women till they are in some degree independent of men; nay, it is vain to expect that strength of natural affection which would make them good wives and mothers. Whilst they are absolutely dependent on their husbands they will be cunning, mean, and selfish.

Do nothing, only keep agitating, debating; and things will destroy themselves.

To which we may add this other Aristotelian consideration, that he who confers a benefit on any one loves him better than he is beloved by him again.

Concern should drive us into action and not into a depression.

The effects of mescalin or LSD can be, in some respects, far more satisfying than those of alcohol. To begin with, they last longer; they also leave behind no hangover, and leave the mental faculties clear and unimpaired. They stimulate the faculties and produce the ideal ground for a peak experience.

Morally, it is wrong to suppose the source of evil is outside oneself, that one is a vessel of holiness running over with virtue. Such a disposition is the best soil for a hateful and cruel fanaticism. It is as wrong to impute every wickedness to Jews, Freemasons, "intellectuals," as it is to blame all crimes on the bourgeoisie, the nobility, and the powers that were. No; the root of evil is in me as well, and I must take my share of the responsibility and the blame. That was true before the revolution and it is true still.

To abjure the notion of the "truly human" is to abjure the attempt to divinize the self as a replacement for a divinized world.

Far from secularization inexorably leading to the death of religion, it has instead given birth to the search for new forms of religious life. The imminent victory of the Kingdom of Reason has never materialized. As a whole, mankind can never get rid of the need for religious self-identification: who am I, where did I come from, where do I fit in, why am I responsible, what does my life mean, how will I face death? Religion is a paramount aspect of human culture. Religious need cannot be excommunicated from culture by rationalist incantation. Man does not live by reason alone.

The limits of my language mean the limits of my world. (5.6) Variant translations: The limits of my language stand for the limits of my world. The limits of my language are the limits of my mind. All I know is what I have words for.

The Platonic doctrine of Ideas has been, in all ages, the derision of the vulgar, and the admiration of the wife. Indeed, if we consider that ideas are the most sublime objects of speculation, and that their nature is no less bright in itself, than difficult to investigate, this opposition in the conduct of mankind will be natural and necessary; for, from our connection with a material nature, our intellectual eye, previous to the irradiations of science, is as ill adapted to objects the most splendid of all, "as the eyes of bats to the light of day.

I feel awe of the gods, I love, I revere, I venerate them, and in short have precisely the same feelings towards them as one would have towards kind masters or teachers or fathers or guardians or any beings of that sort.

We are so captivated by and entangled in our subjective consciousness that we have forgotten the age-old fact that God speaks chiefly through dreams and visions.

The kingdom of heaven can be compared to a king who wanted to settle accounts with his slaves.

The Indian knew how to live without wants, to suffer without complaint, and to die singing.

Today those who peer into the future want only relief from anxiety. Unable to face the prospect that the cycles of war will continue, they are desperate to find a pattern of improvement in history. It is only natural that believers in reason, lacking any deeper faith and too feeble to tolerate doubt, should turn to the sorcery of numbers. Happily there are some who are ready to assist them. Just as the Elizabethan magus transcribed tables shown to him by angels, the modern scientific scryer deciphers numerical auguries of angels hidden in ourselves.

The baby, assailed by eyes, ears, nose, skin, and entrails at once, feels it all as one great blooming, buzzing confusion; and to the very end of life, our location of all things in one space is due to the fact that the original extents or bignesses of all the sensations which came to our notice at once, coalesced together into one and the same space.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.

In 1970s Britain, conservative philosophy was the preoccupation of a few half-mad recluses.

You can take away a man's gods, but only to give him others in return.

Adversity is sometimes hard upon a man; but for one man who can stand prosperity, there are a hundred that will stand adversity. (Often shortened to "can't stand prosperity" as an unknown quote).

There is probably no more abused a term in the history of philosophy than "representation," and my use of this term differs both from its use in traditional philosophy and from its use in contemporary cognitive psychology and artificial intelligence.... The sense of "representation" in question is meant to be entirely exhausted by the analogy with speech acts: the sense of "represent" in which a belief represents its conditions of satisfaction is the same sense in which a statement represents its conditions of satisfaction. To say that a belief is a representation is simply to say that it has a propositional content and a psychological mode.

In Nietzsche's view nihilism is not a Weltanschauung that occurs at some time and place or another; it is rather the basic character of what happens in Occidental history.

Whenever a system of communication evolves, there is always the danger that some will exploit the system for their own ends.

Government was intended to suppress injustice, but it offers new occasions and temptations for the commission of it.

While in the West, the insane are so many that they are put in an asylum, in China the insane are so unusual that we worship them, as anybody who has a knowledge of Chinese literature will testify.

I hate victims who respect their executioners.

An unpleasant nest of nasty, materialistic and aggressive people, careless of the rights of others, imperfectly democratic at home though quick to see the minor slaveries of others, and greedy without end.

I moreover affirm that our wisdom itself, and wisest consultations, for the most part commit themselves to the conduct of chance.

In countries where associations are free, secret societies are unknown. In America there are factions, but no conspiracies.

A Parliament speaking through reporters to Buncombe and the twenty-seven millions, mostly fools.

Every valuable human being must be a radical and a rebel, for what he must aim at is to make things better than they are.

The poverty of the incapable, the distresses that come upon the imprudent, the starvation of the idle, and those shoulderings aside of the weak by the strong, which leave so many "in shallows and in miseries," are the decrees of a large, far-seeing benevolence.

Reverence for life, veneratio vitæ, is the most direct and at the same time the profoundest achievement of my will-to-live. In reverence for life my knowledge passes into experience. The simple world- and life-affirmation which is within me just because I am will-to-live has, therefore, no need to enter into controversy with itself, if my will-to-live learns to think and yet does not understand the meaning of the world. In spite of the negative results of knowledge, I have to hold fast to world- and life-affirmation and deepen it. My life carries its own meaning in itself. This meaning lies in my living out the highest idea which shows itself in my will-to-live, the idea of reverence for life. With that for a starting-point I give value to my own life and to all the will-to-live which surrounds me, I persevere in activity, and I produce values.

Nothing more strikingly betrays the credulity of mankind than medicine. Quackery is a thing universal, and universally successful. In this case it becomes literally true that no imposition is too great for the credulity of men.

The habit of the religious way of thinking has biased our mind so grievously that we are - terrified at ourselves in our nakedness and naturalness; it has degraded us so that we deem ourselves depraved by nature, born devils.

The man described for us, whom we are invited to free, is already in himself the effect of a subjection much more profound than himself. A 'soul' inhabits him and brings him to existence...the soul is the effect and instrument of political anatomy; the soul is the prison of the body.
