Philosophy, as I understand the word, is a positive theoretical science, and a science in an early stage of development. As such it has no more to do with belief than any other science. Indeed, I am bound to confess that it is at present in so unsettled a condition, that if the ordinary theorems of molecular physics and of archaeology are but the ghosts of beliefs, then to my mind, the doctrines of the philosophers are little better than the ghosts of ghosts. I know this is an extremely heretical opinion.

To live in a saint's heart? I'm afraid of setting the sky ablaze.

It is the mark of an educated man to look for precision in each class of things just so far as the nature of the subject admits; it is evidently equally foolish to accept probable reasoning from a mathematician and to demand from a rhetorician scientific proofs.

The moment we no longer have a free press, anything can happen. What makes it possible for a totalitarian or any other dictatorship to rule is that people are not informed; how can you have an opinion if you are not informed? If everybody always lies to you, the consequence is not that you believe the lies, but rather that nobody believes anything any longer. This is because lies, by their very nature, have to be changed, and a lying government has constantly to rewrite its own history. On the receiving end you get not only one lie - a lie which you could go on for the rest of your days - but you get a great number of lies, depending on how the political wind blows. And a people that no longer can believe anything cannot make up its mind. It is deprived not only of its capacity to act but also of its capacity to think and to judge. And with such a people you can then do what you please.

When navigators... determine a longitude... they must... calculate Paris time…with a chronometer set for Paris. The qualitative problem of simultaneity is made to depend upon the quantitative problem of the measurement of time.

I don't know what your destiny will be, but one thing I know, the only ones among you who will be really happy are those who have sought and found how to serve.

He also said to them, "You completely invalidate God's command in order to maintain your tradition! For Moses said: Honor your father and your mother; and, Whoever speaks evil of father or mother must be put to death.

I cannot imagine how the clockwork of the universe can exist without a clockmaker.

The world is sacred because it gives an inkling of a meaning that escapes us.

This in turn suggests an answer to our question: what happened between the birth of De Sade and the birth of Krafft-Ebbing? The rise of the novel taught Europe to use its imagination. And when imagination was applied to sex, the result was the rise of pornography -- and of "sexual perversion."

Books ... hold within them the gathered wisdom of humanity, the collected knowledge of the world's thinkers, the amusement and excitement built up by the imaginations of brilliant people. Books contain humor, beauty, wit, emotion, thought, and, indeed, all of life. Life without books is empty.

One has to do something new in order to see something new.

Chance seldom interferes with the wise man; his greatest and highest interests have been, are, and will be, directed by reason throughout his whole life.

As for the Soothsayer, although I am certain no one feels the true beauties of that work better than I, I am far from finding these beauties in the same places as the infatuated public does. They are not the products of study and knowledge, but rather are inspired by taste and sensitivity.

The Idea of Cause is expressed for purposes of science by these three Axioms:-'Every Event must have a Cause':-'Causes are measured by their Effects':-'Reaction is equal and opposite to Action'.

Great men, great nations, have not been boasters and buffoons, but perceivers of the terror of life, and have manned themselves to face it.

From the same it proceedeth,that men gives different names, to one and the same thing, from the difference of their own passions: As they that approve a private opinion, call it Opinion; but they that mislike it, Haeresie: and yet haeresie signifies no more than private opinion; but has only agreater tincture of choler.

Needs must it be hard, since it is so seldom found. How would it be possible, if salvation were ready to our hand, and could without great labour be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

All words at every level of prose and poetry and all devices of language and speech derive their meaning from figure / ground relation.

First Shakespeare sonnets seem meaningless; first Bach fugues, a bore; first differential equations, sheer torture. But training changes the nature of our spiritual experiences. In due course, contact with an obscurely beautiful poem, an elaborate piece of counterpoint or of mathematical reasoning, causes us to feel direct intuitions of beauty and significance. It is the same in the moral world.

A screen bans reality.

I go to spread the tidings, I want to spread the tidings - of what? Of the truth, for I have seen it, have seen it with my own eyes, have seen it in all its glory.

The best thing about the sciences is their philosophical ingredient, like life for an organic body. If one dephilosophizes the sciences, what remains left? Earth, air, and water.

Any religion or philosophy which is not based on a respect for life is not a true religion or philosophy.

World-view is a product of life-view, not vice versa.

Who is there that can recognize real intellect, and do reverence to it; and discriminate it well from sham intellect, which is so much more abundant, and deserves the reverse of reverence? He that himself has it!-One really human Intellect, invested with command, and charged to reform Downing Street for us, would continually attract real intellect to those regions, and with a divine magnetism search it out from the modest corners where it lies hid. And every new accession of intellect to Downing Street would bring to it benefit only, and would increase such divine attraction in it, the parent of all benefit there and elsewhere!

Anxiety - or the fanaticism of the worst.

The highest ensign that men ever met and embraced under, the Cross itself, had no meaning save an accidental extrinsic one.

In dealing with relationships, not only man-to-man, but also State-to-State and race-to-race, it is necessary to be able to conceive again of that obedience which does not humiliate but exalts, that command or leadership which commits one to superiority and a precise responsibility.

If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?

Virtue is debased by self-justification.

When we consider the being and substance of that universe in which we are immutably set, we shall discover that neither we ourselves nor any substance doth suffer death; for nothing is in fact diminished in its substance, but all things, wandering through infinite space, undergo change of aspect.

Science fiction offers its writers chances of embarrassment that no other form of fiction does.

Prove your words by your deeds.

Much of junk culture has a core of crisis - shoot-outs, conflagrations, bodies weltering in blood, naked embracers or rapist-stranglers. The sounds of junk culture are heard over a ground bass of extremism. Our entertainments swarm with specters of world crisis. Nothing moderate can have any claim to our attention.

He that knows anything, knows this, in the first place, that he need not seek long for instances of his ignorance.

We Jews have been too adaptable. We have been too eager to sacrifice our idiosyncrasies for the sake of social conformity. ... Even in modern civilization, the Jew is most happy if he remains a Jew.

Habit... makes the endurance of evil easy (which, under the name of patience, is falsely honored as a virtue), because sensations of the same type, when continued without alteration for a long time, draw our attention away from the senses so that we are scarcely conscious of them at all. On the other hand, habit also makes the consciousness and the remembrance of good that has been received more difficult, which then gradually leads to ingratitude (a real vice). [...] Acquired habit deprives good actions of their moral value because it undermines mental freedom and, moreover, it leads to thoughtless repetitions of the same acts (monotony), and thus becomes ridiculous.

The thirst after happiness is never extinguished in the heart of man.

I had obtained some distinction, and felt myself of some importance, before the desire of distinction and of importance had grown into a passion: and little as it was which I had attained, yet having been attained too early, like all pleasures enjoyed too soon, it had made me blasé and indifferent to the pursuit. Thus neither selfish nor unselfish pleasures were pleasures to me. And there seemed no power in nature sufficient to begin the formation of my character anew, and create in a mind now irretrievably analytic, fresh associations of pleasure with any of the objects of human desire.

It is best to bear what cannot be changed.

Brief and powerless is Man's life; on him and all his race the slow, sure doom falls pitiless and dark.

To say that man is a compound of strength and weakness, light and darkness, smallness and greatness, is not to indict him, it is to define him.

The teaching of my philosophy... that our whole existence is something which had better not have been, and that to disown and disclaim it is the highest wisdom.

When the happiness or misery of others depends in any respect upon our conduct, we dare not, as self-love might suggest to us, prefer the interest of one to that of many. The man within immediately calls to us, that we value ourselves too much and other people too little, and that, by doing so, we render ourselves the proper object of the contempt and indignation of our brethren. Neither is this sentiment confined to men of extraordinary magnanimity and virtue. It is deeply impressed upon every tolerably good soldier, who feels that he would become the scorn of his companions, if he could be supposed capable of shrinking from danger, or of hesitating, either to expose or to throw away his life, when the good of the service required it.

Whenever government assumes to deliver us from the trouble of thinking for ourselves, the only consequences it produces are those of torpor and imbecility.

Institutionalized desublimation thus appears to be an aspect of the "conquest of transcendence" achieved by the one-dimensional society. Just as this society tends to reduce, and even absorb opposition (the qualitative difference!) in the realm of politics and higher culture, so it does in the instinctual sphere. The result is the atrophy of the mental organs for grasping the contradictions and the alternatives and, in the one remaining dimension of technological rationality, the Happy Consciousness comes to prevail.
