The fear of your own solitude, of its vast surface and its infinity... Remorse is the voice of solitude. And what does this whispering voice say? Everything in us that is not human anymore.

If the world is a precipitation of human nature, so to speak, then the divine world is a sublimation of the same. Both occur in one act. No precipitation without sublimation. What goes lost there in agility, is won here.

I am sure that university life would be better, both intellectually and morally, if most university students had temporary childless marriages. This would afford a solution to the sexual urge neither restless nor surreptitious, neither mercenary nor casual, and of such a nature that it need not take up time which ought to be given to work.

If people should ever start to do only what is necessary millions would die of hunger.

Use these rules then, and trouble thyself about nothing else.

In America a woman loses her independence for ever in the bonds of matrimony. While there is less constraint on girls there than anywhere else, a wife submits to stricter obligations. For the former, her father's house is a home of freedom and pleasure; for the latter, her husband's is almost a cloister.

Thank you for your letter and for the enclosure which I return herewith. I have been wondering whether there is any means of preventing the confusion between you and me, and I half-thought that we might write a joint letter to The Times in the following terms: Sir, To prevent the continuation of confusions which frequently occur, we beg to state that neither of us is the other. Do you think this would be a good plan?

Art is the perfection of nature.

And killing time is perhaps the essence of comedy, just as the essence of tragedy is killing eternity.

And striving to be man, the worm Mounts through all the spires of form.

Error is the force that welds men together; truth is communicated to men only by deeds of truth. Only deeds of truth, by introducing light into the conscience of each individual, can dissolve the cohesion of error, and detach men one by one from the mass united together by the cohesion of error.

Generosity is nothing else than a craze to possess. All which I abandon, all which I give, I enjoy in a higher manner through the fact that I give it away.... To give is to enjoy possessively the object which one gives.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more upon it. A strength which becomes clearer and stronger through its experience of such obstacles is the only strength that can conquer them. Resistance is only a waste of strength.

The poem of the understanding is philosophy.

The male has more teeth than the female in mankind, and sheep, and goats, and swine. This has not been observed in other animals.

The original thinking force of the universe progresses and develops itself in all possible determinations of which it is capable, just as the other original natural forces progress and assume all possible configurations. I am a particular determination of the formative force, like the plant; a particular determination of the peculiar motive force, like the animal; and in addition to this a determination of the thinking force: and the union of these three basic forces into one force, into one harmonious development, is the distinguishing characteristic of my species.

We have two ears and one mouth, so we should listen more than we say.

Falling in love is the one illogical adventure, the one thing of which we are tempted to think as supernatural, in our trite and reasonable world. The effect is out of all proportion with the cause. Two persons, neither of them, it may be, very amiable or very beautiful, meet, speak a little, and look a little into each other's eyes. That has been done a dozen or so of times in the experience of either with no great result. But on this occasion all is different. They fall at once into that state in which another person becomes to us the very gist and centrepoint of God's creation, and demolishes our laborious theories with a smile; in which our ideas are so bound up with the one master-thought that even the trivial cares of our own person become so many acts of devotion, and the love of life itself is translated into a wish to remain in the same world with so precious and desirable a fellow-creature.

Is not marriage an open question, when it is alleged, from the beginning of the world, that such as are in the institution wish to get out, and such as are out wish to get in?

Pithy sentences are like sharp nails which force truth upon our memory.

In a free nation, it matters not whether individuals reason well or ill; it is sufficient that they do reason. Truth arises from the collision and from hence springs liberty, which is a security from the effects of reasoning.

In a shared fish, there are no bones.

We plant trees, we build stone houses, we redeem the waste, we make prospective laws, we found colleges and hospitals, for remote generations.

Historians of ideas, however scrupulous and minute they may feel it necessary to be, cannot avoid perceiving their material in terms of some kind of pattern.

An optimistic view of the future would indicate that before long, the clear necessity of expanding humanity's horizons would cause ... space settlements to be built. The construction would also serve as a great project that not only would be clearly of great benefit, but might induce human cooperation in something large enough to fire the heart and mind, and make people forget the petty quarrels that have engaged them for thousands of years in wars over insignificant scraps of earthly territory.

Immortality is the privilege of the few, and, according to the Aryan conception, specifically the privilege of heroes. Continuing to live - not as a shadow, but as a demigod - is reserved to those which a special spiritual action has elevated from the one nature to the other.

In such a chain, too, or succession of objects, each part is caused by that which preceded it, and causes that which succeeds it. Where then is the difficulty? But the WHOLE, you say, wants a cause. I answer, that the uniting of these parts into a whole, like the uniting of several distinct countries into one kingdom, or several distinct members into one body, is performed merely by an arbitrary act of the mind, and has no influence on the nature of things. Did I show you the particular causes of each individual in a collection of twenty particles of matter, I should think it very unreasonable, should you afterwards ask me, what was the cause of the whole twenty. This is sufficiently explained in explaining the cause of the parts.

All art is but imitation of nature.

The meaning and design of a problem seem not to lie in its solution, but in our working at it incessantly.

There are no connections in resonant space. There are only interfaces and metamorphoses.

Circumstances (which with some gentlemen pass for nothing) give in reality to every political principle its distinguishing colour, and discriminating effect. The circumstances are what render every civil and political scheme beneficial or noxious to mankind.

What has been shown by Machiavelli, who is often (like Nietzsche) congratulated for tearing off hypocritical masks, brutally revealing the truth, and so on, is not that men profess one thing and do another (although no doubt he shows this too) but that when they assume that the two ideals are compatible, or perhaps are even one and the same ideal, and do not allow this assumption to be questioned, they are guilty of bad faith (as the existentialists call it, or of "false consciousness," to use a Marxist formula) which their actual behavior exhibits. Machiavelli calls the bluff not just of official morality-the hypocrisies of ordinary life-but of one of the foundations of the central Western philosophical tradition, the belief in the ultimate compatibility of all genuine values. His own withers are unwrung. He has made his choice. He seems wholly unworried by, indeed scarcely aware of, parting company with traditional Western morality.

How much good it would do if one could exterminate the human race.

When asked why people give to beggars but not to philosophers, he replied, 'Because they expect they may become lame and blind, but never that they will become philosophers.'

I am a dreamer of words, of written words. I think I am reading; a word stops me. I leave the page. The syllables of the word begin to move around. Stressed accents begin to invert. The word abandons its meaning like an overload which is too heavy and prevents dreaming. Then words take on other meanings as if they had the right to be young. And the words wander away, looking in the nooks and crannies of vocabulary for new company, bad company.

The only minds which seduce us are the minds which have destroyed themselves trying to give their life a meaning.

To be an intellectual really means to speak a truth that allows suffering to speak. That is, it creates a vision of the world that puts into the limelight the social misery that is usually hidden or concealed by the dominant viewpoints of a society. "Intellectual" in that sense simply means those who are willing to reflect critically upon themselves as well as upon the larger society and to ascertain whether there is some possibility of amelioration and betterment.

Countless attempts have been made to no avail to construct a continuity from the supreme principle of the intellectual world to the finite world. The oldest and most frequent of these attempts is well known: the principle of emanation, according to which the outflowings from the godhead, in gradual increments and detachment from the ordinary source, losing their divine perfection until, in the end, they pass into the opposite (matter, privation), just as light is finally confined by darkness.

Students have powerful images of what a perfect body is and pursue it incessantly. But deprived of literary guidance, they no longer have any image of a perfect soul, and hence do not long to have one.

Those who cannot find moral clarity are likely to settle for the far more dangerous simplicity, or purity, instead.

The Christian Religion not only was at first attended with miracles, but even at this day cannot be believed by any reasonable person without one. Mere reason is insufficient to convince us of its veracity: and whoever is moved by Faith to assent to it, is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience.

Omnipotence and foreknowledge of God, I repeat, utterly destroy the doctrine of 'free-will' ... doubtless it gives the greatest possible offense to common sense or natural reason, that God, Who is proclaimed as being full of mercy and goodness, and so on, should of His own mere will abandon, harden and damn men, as though He delighted in the sins and great eternal torments of such poor wretches. It seems an iniquitous, cruel, intolerable thought to think of God; and it is this that has been such a stumbling block to so many great men down through the ages. And who would not stumble at it? I have stumbled at it myself more than once, down to the deepest pit of despair, so that I wished I had never been made a man.

The best people renounce all for one goal, the eternal fame of mortals; but most people stuff themselves like cattle. For what sense or understanding have they? They follow minstrels and take the multitude for a teacher, not knowing that many are bad and few good. For the best men choose one thing above all immortal glory among mortals; but the masses stuff themselves like cattle.

Every good mathematician is at least half a philosopher, and every good philosopher is at least half a mathematician.
