One might call habit a moral friction: something that prevents the mind from gliding over things but connects it with them and makes it hard for it to free itself from them.

The proof of a theory is in its reasoning, not in its sponsorship.

Atheists have the intellectual courage to accept reality for what it is: wonderfully and shockingly explicable. As an atheist, you have the moral courage to live to the full the only life you're ever going to get: to fully inhabit reality, rejoice in it, and do your best finally to leave it better than you found it.

It is terrible when people do not know God, but it is worse when people identify as God what is not God.

The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

There is merely bad luck in not being loved; there is misfortune in not loving. All of us, today, are dying of this misfortune. For violence and hatred dry up the heart itself; the long fight for justice exhausts the love that nevertheless gave birth to it.

We make choices, decisions, as long as we keep to the surface of things; once we reach the depths, we can neither choose nor decide, we can do nothing but regret the surface...

Music is the poor man's Parnassus.

Eat not the heart.

Man starts over again everyday, in spite of all he knows, against all he knows.

I cannot think of any circumstances in which advertising would not be an evil.

By what aberration has suicide, the only truly normal action, become the attribute of the flawed?

And above all, we must feel and act as if an endless continuation of our earthly life awaited us after death; and if it be that nothingness is the fate that awaits us we must not, in the words of Obermann, so act that it shall be a just fate.

Bush and bin Laden are really on the same side: the side of faith and violence against the side of reason and discussion. Both have implacable faith that they are right and the other is evil. Each believes that when he dies he is going to heaven. Each believes that if he could kill the other, his path to paradise in the next world would be even swifter. The delusional "next world" is welcome to both of them. This world would be a much better place without either of them.

Martyrs must choose between being forgotten, mocked, or made use of. As for being understood, never!

Tell them I've had a wonderful life.

There is no wish more natural than the wish to know.

New technological environments are commonly cast in the molds of the preceding technology out of the sheer unawareness of their designers.

This is a strange -- and rather alarming -- realisation. For it clearly implies that masturbation is one of our highest faculties that human beings have developed. Many animals masturbate -- but never without the presence of another animal, or some similar stimulus. A human being can masturbate in an empty room: a triumph of pure imagination.

Superstition, idolatry, and hypocrisy have ample wages, but truth goes a-begging.

The real is not only what can be reproduced, but that which is already reproduced, the hyper-real.

Well, since paradoxes are at hand, let us see how it might be demonstrated that in a finite continuous extension it is not impossible for infinitely many voids to be found.

Science is a systematic method for studying and working out those generalizations that seem to describe the behavior of the universe. It could exist as a purely intellectual game that would never affect the practical life of human beings either for good or evil, and that was very nearly the case in ancient Greece, for instance. Technology is the application of scientific findings to the tools of everyday life, and that application can be wise or unwise, useful or harmful. Very often, those who govern technological decisions are not scientists and know little about science.

I use the word nursing for want of a better. It has been limited to signify little more than the administration of medicines and the application of poultices. It ought to signify the proper use of fresh air, light, warmth, cleanliness, quiet, and the proper selection and administration of diet - all at the least expense of vital power to the patient.

Driving is a spectacular form of amnesia. Everything is to be discovered, everything to be obliterated. Admittedly, there is the primal shock of the deserts and the dazzle of California, but when this is gone, the secondary brilliance of the journey begins, that of the excessive, pitiless distance, the infinity of anonymous faces and distances, or of certain miraculous geological formations, which ultimately testify to no human will, while keeping intact an image of upheaval. This form of travel admits of no exceptions: when it runs up against a known face, a familiar landscape, or some decipherable message, the spell is broken: the amnesic, ascetic, asymptotic charm of disappearance succumbs to affect and worldly semiology.

But yet they that have no Science, are in better, and nobler condition with their naturall Prudence; than men, that by their mis-reasoning, or by trusting them that reason wrong, fall upon false and absurd generall rules.

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another ... has even less worth than if he were a mere thing. ... makes himself a mere deceptive appearance of man, not man himself.

I am often accused of expressing contempt and despising religious people. I don't despise religious people, I despise what they stand for. I like to quote the British journalist Johann Hari who said, "I have so much respect for you, that I cannot respect your ridiculous ideas."

Any plea ... for institutionalized risk-assessment, beefed-up bioethics panels, academic review bodies, worse-case scenario planning, more intensive computer simulations, systematic long-term planning and the institutionalized study of existential risks is admirable. But so is urgent action to combat the global pandemic of suffering. "The easiest pain to bear is someone else's"

For it is with the same imperialism that present-day simulators try to make the real, all of the real, coincide with their simulation models.

I speak as a biologist. There aren't many absolutely clear distinctions in biology. Mostly what we have is a spectrum. But the male-female divide is exceptional in biology. It really is a true binary.

The philosophy of Bergson, which is a spiritualist restoration, essentially mystical, medieval, Quixotesque, has been called a demi-mondaine philosophy. Leave out the demi; call it mondaine, mundane. Mundane - yes, a philosophy for the world and not for philosophers, just as chemistry ought to be not for chemists alone. The world desires illusion (mundus vult decipi) - either the illusion antecedent to reason, which is poetry, or the illusion subsequent to reason, which is religion. And Machiavelli has said that whosoever wishes to delude will always find someone willing to be deluded. Blessed are they who are easily befooled!

A Dialogue between two Infants in the womb concerning the state of this world, might handsomely illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

I have in general no very exalted opinion of the virtue of paper government.

Of how much more passion than reason has Jupiter composed us? putting in, as one would say, "scarce half an ounce to a pound."

Many receive advice, few profit by it.

Someday, someday, this crazy world will have to end, And our God will take things back that He to us did lend. And if, on that sad day, you want to scold our God, Why go right ahead and scold Him. He'll just smile and nod.

All abstract sciences are nothing but the study of relations between signs.

It seems to me obvious that infants and many animals that do not in any ordinary sense have a language or perform speech acts nonetheless have Intentional states. Only someone in the grip of a philosophical theory would deny that small babies can literally be said to want milk and that dogs want to be let out or believe that their master is at the door.

The cup of life is not so shallow

That we have drained the best 

That all the wine at once we swallow 

And lees make all the rest.

I do not understand! I understand nothing! I cannot understand nor do I want to understand! I want to believe! To Believe!

This species works intentionally on its own destruction (by war). This, however, does not keep the rational creatures of such a constantly advancing culture, even in the midst of war, from promising to mankind in coming centuries an unequivocal prospect of bliss which will never end.

For myself I say deliberately, it is better to have a millstone tied round the neck and be thrown into the sea than to share the enterprises of those to whom the world has turned, and will turn, because they minister to its weaknesses and cover up the awful realities which it shudders to look at.

Then he tried to recall the lessons of Mr. Wisdom. "it is I myself, eternal Spirit, who drives this Me, the slave, along that ledge. I ought not to care whether he falls and breaks his neck or not. It is not he that is real, it is I - I - I.

It is false that kings are entitled to the eminence they obtain. They possess no intrinsic superiority over their subjects. The line of distinction that is drawn is the offspring of pretense, an indirect means employed for effecting certain purposes, and not the language of truth. It tramples upon the genuine nature of things, and depends for its support upon this argument, 'that, were it not for impositions of a similar nature, mankind would be miserable.'

I see myself immersed in the depths of human existence and standing in the face of the ineffable mystery of the world and of all that is. And in that situation, I am made poignantly and burningly aware that the world cannot be self-sufficient, that there is hidden in some still greater depth a mysterious, transcendent meaning. This meaning is called God. Men have not been able to find a loftier name, although they have abused it to the extent of making it almost unutterable. God can be denied only on the surface; but he cannot be denied where human experience reaches down beneath the surface of flat, vapid, commonplace existence.

The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful. The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. And this is by no means so difficult a task as the history of philosophy would lead one to suppose. For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.
