Truth lives, in fact, for the most part on a credit system. Our thoughts and beliefs 'pass,' so long as nothing challenges them, just as bank-notes pass so long as nobody refuses them.

The republican is the only form of government which is not eternally at open or secret war with the rights of mankind.

Alas! Your dear friend and servant Galileo has been for the last month hopelessly blind; so that this heaven, this earth, this universe, which I by my marvelous discoveries and clear demonstrations had enlarged a hundred thousand times beyond the belief of the wise men of bygone ages, henceforward for me is shrunk into such a small space as is filled by my own bodily sensations.

The most important part of education - to teach the meaning of to know (in the scientific sense). The last statement in her notebook

Christianity was an epidemic rather than a religion. It appealed to fear, hysteria and ignorance. It spread across the Western world, not because it was true, but because humans are gullible and superstitious.

It seems to me that the current political task in a society like ours is to criticize the working of institutions that are apparently the most neutral and independent, to criticize these institutions and attack them in such a way that the political violence that exercises itself obscurely through them becomes manifest, so that one can fight against them.

What the sorrowful Jew of Amsterdam called the essence of a thing, the effort that it makes to persist indefinitely in its own being, self-love, the longing for immortality, is it not perhaps the primal and fundamental condition of all reflective or human knowledge? And is it not therefore the true base, the real starting-point, of all philosophy, although the philosophers, perverted by intellectualism, do not recognize it?

Given that annihilation of nature in its entirety is impossible, and that death and dissolution are not appropriate to the whole mass of this entire globe or star, from time to time, according to an established order, it is renewed, altered, changed, and transformed in all its parts.

In the long run, there is nothing to stop intelligent agents from identifying the molecular signature of experience below hedonic zero and eliminating it altogether - even in insects. Nociception is vital; pain is optional. I tentatively predict that the world's last unpleasant experience in our forward light-cone will be a precisely datable event - perhaps some micro-pain in an obscure marine invertebrate a few centuries hence.

When we put our central nervous system outside us we returned to the primal nomadic state.

The Union was a measure from which infinite Good has been derived to this country.

A happy man or woman is a better thing to find than a five-pound note. He or she is a radiating focus of goodwill; and their entrance into a room is as though another candle had been lighted. We need not care whether they could prove the forty-seventh proposition; they do a better thing than that, they practically demonstrate the great Theorem of the Liveableness of Life.

It is the season of the Kronia, during which the god allows us to make merry. But, my dear friend, as I have no talent for amusing or entertaining I must methinks take pains not to talk mere nonsense." "But, Caesar, can there be anyone so dull and stupid as to take pains over jesting? I always thought that such pleasantries were a relaxation of the mind and a relief from pains and cares." "Yes, and no doubt your view is correct, but that is not how the matter strikes me. For by nature I have no turn for raillery, or parody, or raising a laugh."

People never remember but the computer never forgets.

All things are in the Universe, and the universe is in all things: we in it, and it in us; in this way everything concurs in a perfect unity.

If Governments neglect to invite what noble intellect there is, then too surely all intellect, not omnipotent to resist bad influences, will tend to become beaverish ignoble intellect; and quitting high aims, which seem shut up from it, will help itself forward in the way of making money and such like; or will even sink to be sham intellect, helping itself by methods which are not only beaverish but vulpine, and so "ignoble" as not to have common honesty.

That which makes the man no worse than he was makes his life no worse: it has no power to harm, without or within.

I am an American, Chicago born - Chicago, that somber city - and go at things as I have taught myself, free-style, and will make the record in my own way: first to knock, first admitted; sometimes an innocent knock, sometimes a not so innocent.

You must lay aside the burdens of the mind; until you do this, no place will satisfy you.

Is it conceivable to adhere to a religion founded by someone else?

When I was 4 years old ... I dreamt that I'd been eaten by a wolf, and to my great surprise I was in the wolf's stomach and not in heaven.

Why in the world shouldn't they have regarded with awe and reverence that act by which the human race is perpetuated. Not every religion has to have St. Augustine's attitude to sex. Why even in our culture marriages are celebrated in a church, everyone present knows what is going to happen that night, but that doesn't prevent it being a religious ceremony.

The meaning of relativity has been widely misunderstood. Philosophers play with the word, like a child with a doll. Relativity, as I see it, merely denotes that certain physical and mechanical facts, which have been regarded as positive and permanent, are relative with regard to certain other facts in the sphere of physics and mechanics. It does not mean that everything in life is relative and that we have the right to turn the whole world mischievously topsy-turvy.

It may seem to be a long way from Blake's innocent talk of love and copulation to De Sade's need to inflict pain. And yet both are the outcome of a sexual mysticism that strives to transcend the everyday world. Simone de Beauvoir said penetratingly of De Sade's work that 'he is trying to communicate an experience whose distinguishing characteristic is, nevertheless its will to remain incommunicable'. De Sade's perversion may have sprung from his dislike of his mother or of other women, but its basis is a kind of distorted religious emotion.

For those of us who have been thrown into hell, mysterious melodies and the torturing images of a vanished beauty will always bring us, in the midst of crime and folly, the echo of that harmonious insurrection which bears witness, throughout the centuries, to the greatness of humanity.

At best the principles that economists have supposed the choices of rational individuals to satisfy can be presented as guidelines for us to consider when we make our decisions.

I am attached to Christianity at large; much from conviction; more from affection.

When a philosopher addresses himself to... a tyrant, and tells him... tyranny is incompatible with justice, then the philosopher speaks... and believes he is speaking the truth, and... takes a risk...

Do I write out of love to men? No, I write because I want to procure for my thoughts an existence in the world; and, even if I foresaw that these thoughts would deprive you of your rest and your peace, even if I saw the bloodiest wars and the fall of many generations springing up from this seed of thought - I would nevertheless scatter it. Do with it what you will and can, that is your affair and does not trouble me.

We are reformers in spring and summer; in autumn and winter we stand by the old - reformers in the morning, conservatives at night. Reform is affirmative, conservatism is negative; conservatism goes for comfort, reform for truth.

Search men's governing principles, and consider the wise, what they shun and what they cleave to.

Whether or not there exists a solution to problems troubles only a minority; that the emotions have no outcome, lead to nothing, vanish into themselves - that is the great unconscious drama, the affective insolubility everyone suffers without even thinking about it.

I discuss with myself questions of politics, love, taste, or philosophy. I let my mind rove wantonly, give it free rein to follow any idea, wise or mad that may present itself. ... My ideas are my harlots.

Let the modern eye look earnestly on that old midnight hour in St. Edmundsbury Church, shining yet on us, ruddy-bright, through the depths of seven hundred years; and consider mournfully what our Hero-worship once was, and what it now is!

A great prison structure was planned, whose different levels would correspond exactly to the levels of the centralized administration. The scaffold, where the body of the tortured criminal had been exposed to the ritually manifested force of the sovereign, the punitive theatre in which the representation of punishment was permanently available to the social body, was replaced by a great enclosed, complex and hierarchized structure that was integrated into the very body of the state apparatus.

As a rule we disbelieve all the facts and theories for which we have no use.

It is better; heavier, crueler. The mouth you wear for hell.

It must be emphasized that the warrior spirit is one thing and the military spirit quite another. Militarism was unknown in the Middle Ages. The soldier signifies the degeneration of the warrior, corrupted by the industrialist. The soldier is an armed industrialist, a bourgeois who has invented gunpowder. He was organized by the state to make war on the castles. With his coming, long-distance warfare appeared, the abstract war waged by cannon and machine gun.

As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and aesthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?

Living, loving, being natural or sincere-all these are spontaneous forms of behavior: they happen "of themselves" like digesting food or growing hair. As soon as they are forced they acquire that unnatural, contrived, and phony atmosphere which everyone deplores-weak and scentless like forced flowers and tasteless like forced fruit. Life and love generate effort, but effort will not generate them. Faith-in life, in other people, and in oneself-is the attitude of allowing the spontaneous to be spontaneous, in its own way and in its own time.

The history of philosophical system is the picture gallery of reason.

I find that the whiter my hair becomes the more ready people are to believe what I say.

All those instances to be found in history, whether real or fabulous, of a doubtful public spirit, at which morality is perplexed, reason is staggered, and from which affrighted Nature recoils, are their chosen and almost sole examples for the instruction of their youth.
