Mathematics is as little a natural science as philosophy is one of the humanities. Philosophy in its essence belongs as little in the philosophical faculty as mathematics belongs to natural science. To house philosophy and mathematics in this way today seems to be a blemish or a mistake in the catalog of the universities. Plato put over the entrance to his Academy the words: "Let no one who has not grasped the mathematical enter here!"

And suddenly I had an inkling of what it must feel like to be mad.

Is a democracy, such as we know it, the last improvement possible in government? Is it not possible to take a step further towards recognizing and organizing the rights of man? There will never be a really free and enlightened State until the State comes to recognize the individual as a higher and independent power, from which all its own power and authority are derived, and treats him accordingly. I please myself with imagining a State at least which can afford to be just to all men, and to treat the individual with respect as a neighbor; which even would not think it inconsistent with its own repose if a few were to live aloof from it, not meddling with it, nor embraced by it, who fulfilled all the duties of neighbors and fellow-men. A State which bore this kind of fruit, and suffered it to drop off as fast as it ripened, would prepare the way for a still more perfect and glorious State, which also I have imagined, but not yet anywhere seen.

All the cruelty and torment of which the world is full is in fact merely the necessary result of the totality of the forms under which the will to live is objectified.

...there are more things to admire in men than to despise.

There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.

Jacques said that his master said that everything good or evil we encounter here below was written on high.

It is characteristic of the most entire sincerity to be able to foreknow. When a nation or family is about to flourish, there are sure to be happy omens; and when it is about to perish, there are sure to be unlucky omens.

Though thou loved her as thyself, As a self of purer clay, Tho' her parting dims the day, Stealing grace from all alive, Heartily know, When half-gods go, The gods arrive.

The wise soul feareth not death; rather she sometimes striveth for death, she goeth beyond to meet her. Yet eternity maintaineth her substance throughout time, immensity throughout space, universal form throughout motion.

I believe it might interest a philosopher, one who can think himself, to read my notes. For even if I have hit the mark only rarely, he would recognize what targets I had been ceaselessly aiming at.

Religion should be .... successively freed from all statutes based on history, and one purely moral religion rule over all, in order that God might be all in all. The veil must fall. The leading-string of sacred tradition with all its appendices becomes by degrees useless, and at last a fetter ... The humiliating difference between laymen and clergymen must disappear, and equality spring from true liberty. All this, however, must not be expected from an exterior revolution, which acts violently, and depends upon fortune In the principle of pure moral religion, which is a sort of divine revelation constantly taking place in the soul of man, must be sought the ground for a passage to the new order of things, which will be accomplished by slow and successive reforms.

What potent blood hath modest May!

The objective of all human arrangements is through distracting one's thoughts to cease to be aware of life.

Mother love is stronger than the filth and scabbiness on a child, and so the love of God toward us is stronger than the dirt that clings to us.

In order to seek truth, it is necessary once in the course of our life, to doubt, as far as possible, of all things.

Courage, not cleverness; not even inspiration, is the grain of mustard that grows up to be a great tree.

Everyone has a goal which appears to be great, at least to himself, and is great when deepest conviction, the innermost voice of the heart, pronounces it great. ... This voice, however, is easily drowned out, and what we thought to be inspiration may have been created by the fleeting moment and again perhaps destroyed by it. ... We must seriously ask ourselves, therefore, whether we are really inspired about a vocation, whether an inner voice approves of it, or whether the inspiration was a deception, whether that which we took as the Deity's calling to us was self-deceit. But how else could we recognize this except by searching for the source of our inspiration?

To be a philosopher, that is to say, a lover of wisdom (for wisdom is nothing but truth), it is not enough for a man to love truth, in so far as it is compatible with his own interest, with the will of his superiors, with the dogmas of the church, or with the prejudices and tastes of his contemporaries; so long as he rests content with this position, he is only a philautos, not a philosophos [a lover of self, not a lover of wisdom]. For this title of honor is well and wisely conceived precisely by its stating that one should love the truth earnestly and with one's whole heart, and thus unconditionally and unreservedly, above all else, and, if need be, in defiance of all else. Now the reason for this is the one previously stated that the intellect has become free, and in this state it does not even know or understand any other interest than that of truth.

He who fears he shall suffer, already suffers what he fears.

The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. WORKING MEN OF ALL COUNTRIES, UNITE!

I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation.

Kripke tries to sober us up by denying that meaning determines reference. Rather, we name things by confronting them and baptising them, not by creating them out of a list of qualities. Names are not, pace Russell, shorthand for such lists. They are not abbreviations for descriptions, but (in Kripke's coinage) 'rigid designators' - that is, they would name the same things in any possible world, including worlds in which their bearers did not have the properties we, in this world, use to identify them.

I have been merely oppressed by the weariness and tedium and vanity of things lately: nothing stirs me, nothing seems worth doing or worth having done: the only thing that I strongly feel worth while would be to murder as many people as possible so as to diminish the amount of consciousness in the world. These times have to be lived through: there is nothing to be done with them.

Though the profusion of Government must undoubtedly have retarded the natural progress of England to wealth and improvement, it has not been able to stop it.

The liar is a person who uses the valid designations, the words, in order to make something which is unreal appear to be real. He says, for example, "I am rich," when the proper designation for his condition would be "poor." He misuses fixed conventions by means of arbitrary substitutions or even reversals of names. If he does this in a selfish and moreover harmful manner, society will cease to trust him and will thereby exclude him. What men avoid by excluding the liar is not so much being defrauded as it is being harmed by means of fraud. Thus, even at this stage, what they hate is basically not deception itself, but rather the unpleasant, hated consequences of certain sorts of deception. It is in a similarly restricted sense that man now wants nothing but truth: he desires the pleasant, life-preserving consequences of truth. He is indifferent toward pure knowledge which has no consequences; toward those truths which are possibly harmful and destructive he is even hostilely inclined.

You can hardly convince a man of an error in a lifetime, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be.

The Greeks follow a wrong usage in speaking of coming into being and passing away; for nothing comes into being or passes away, but there is mingling and separation of things that are. So they would be right to call coming into being mixture, and passing away separation.

The right of voting for representatives is the primary right by which other rights are protected. To take away this right is to reduce a man to slavery, for slavery consists in being subject to the will of another, and he that has not a vote in the election of representatives is in this case.

Man cannot will unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth.

Childish and altogether ludicrous is what you yourself are and all philosophers; and if a grown-up man like me spends fifteen minutes with fools of this kind, it is merely a way of passing the time. I've now got more important things to do. Goodbye!

The unity is brought about by force.

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them of clay, in the way Adam was fashioned.

A people that sells its own children is more condemnable than the buyer; this commerce demonstrates our superiority; he who gives himself a master was born to have one.

But men must know that in this theater of man's life it is reserved only for God and angels to be lookers on.

Fortune is lavish with her favors, but not to be depended on. Nature on the other hand is self-sufficing, and therefore with her feebler but trustworthy [resources] she wins the greater [meed] of hope.

With all great deceivers there is a noteworthy occurrence to which they owe their power. In the actual act of deception... they are overcome by belief in themselves. It is this which then speaks so miraculously and compellingly to those who surround them.

Soul, indeed, is a certain medium between an impartible essence, and an essence which is divisible about bodies. But intellect is an impartible essence alone. And qualities and material forms are divisible about bodies. Not everything which acts on another, effects that which it does effect by approximation and contact; but those natures which effect any thing by approximation and contact, use approximation accidentally.

As for us, my little friend, we entered [the Communist Party] because we were tired of dying of hunger.

But how shall we expect charity towards others, when we are uncharitable to ourselves? Charity begins at home, is the voice of the world, yet is every man his greatest enemy, and as it were, his own executioner.

There are various, nay, incredible faiths; why should we be alarmed at any of them? What man believes, God believes.

The hell to be endured hereafter, of which theology tells, is no worse than the hell we make for ourselves in this world by habitually fashioning our characters in the wrong way.

I do not speak the minds of others except to speak my own mind better.

Either Man will abolish war, or war will abolish Man.

Life is one long struggle in the dark.

You called and cried out loud and shattered my deafness. You were radiant and resplendent, you put to flight my blindness. You were fragrant, and I drew in my breath and now pant after you. I tasted you, and I feel but hunger and thirst for you. You touched me, and I am set on fire to attain the peace which is yours.

All traditional logic habitually assumes that precise symbols are being employed. It is therefore not applicable to this terrestial life but only to an imagined celestial existence... logic takes us nearer to heaven than other studies.

I have seen a translation by Hobbes, which I prefer for its greater clumsiness. Many years have passed since I saw it, but it made me laugh immoderately. Poetry that is not good can only make amends for that deficiency by being ridiculous... William Cowper, of Hobbes's translation of Homer, in a letter to Thomas Park (July 15, 1793), published in The Works of William Cowper: His Life and Letters by William Hayley, ed. T. S. Grimshawe, Vol. V (1835), p. 161

Know that death comes to everyone, and that wealth will sometimes be acquired, sometimes lost. Whatever griefs mortals suffer by divine chance, whatever destiny you have, endure it and do not complain. But it is right to improve it as much as you can, and remember this: Fate does not give very many of these griefs to good people.

In short, competition has to shoulder the responsibility of explaining all the meaningless ideas of the economists, whereas it should rather be the economists who explain competition.
