If at times I have thought myself unfortunate, it is because of a confusion, an error. I have mistaken myself for someone else... Who am I really? I am the author of The World as Will and Representation, I am the one who has given an answer to the mystery of Being that will occupy the thinkers of future centuries. That is what I am, and who can dispute it in the years of life that still remain for me?

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

There is no more mistaken path to happiness than worldliness, revelry, high life.

Intellect is invisible to the man who has none.

A man who has no mental needs, because his intellect is of the narrow and normal amount, is, in the strict sense of the word, what is called a philistine.

The truth can wait, for she lives a long life.

Because people have no thoughts to deal in, they deal cards, and try and win one another's money. Idiots!

Monotheistic religions alone furnish the spectacle of religious wars, religious persecutions, heretical tribunals, that breaking of idols and destruction of images of the gods, that razing of Indian temples and Egyptian colossi, which had looked on the sun 3,000 years: just because a jealous god had said, 'Thou shalt make no graven image.'

The law of simplicity and naïveté applies to all fine art, for it is compatible with what is most sublime. True brevity of expression consists in a man only saying what is worth saying, while avoiding all diffuse explanations of things which every one can think out for himself; that is, it consists in his correctly distinguishing between what is necessary and what is superfluous. On the other hand, one should never sacrifice clearness, to say nothing of grammar, for the sake of being brief. To impoverish the expression of a thought, or to obscure or spoil the meaning of a period for the sake of using fewer words shows a lamentable want of judgment.

Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use of the book of the world.

In the sphere of thought, absurdity and perversity remain the masters of the world, and their dominion is suspended only for brief periods.

The chief objection I have to Pantheism is that it says nothing. To call the world "God" is not to explain it; it is only to enrich our language with a superfluous synonym for the word "world".

Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes; this is partly because it gets unobstructed hold of the hearer's mind without his being distracted by secondary thoughts, and partly because he feels that here he is not being corrupted or deceived by the arts of rhetoric, but that the whole effect is got from the thing itself.

The little honesty that exists among authors is discernible in the unconscionable way they misquote from the writings of others.

For a work to become immortal it must possess so many excellences that it will not be easy to find a man who understands and values them all; so that there will be in all ages men who recognise and appreciate some of these excellences; by this means the credit of the work will be retained throughout the long course of centuries and ever-changing interests, for, as it is appreciated first in this sense, then in that, the interest is never exhausted.

A book can never be anything more than the impression of its author's thoughts [Ein Buch kann nie mehr seyn, als der Abdruck der Gedanken des Verfassers]. The value of these thoughts lies either in the matter about which he has thought, or in the form in which he develops his matter - that is to say, what he has thought about it.

No greater mistake can be made than to imagine that what has been written latest is always the more correct; that what is written later on is an improvement on what was written previously; and that every change means progress. Men who think and have correct judgment, and people who treat their subject earnestly, are all exceptions only. Vermin is the rule everywhere in the world: it is always at hand and busily engaged in trying to improve in its own way upon the mature deliberations of the thinkers.

There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. The first kind have had thoughts or experiences which seem to them worth communicating, while the second kind need money and consequently write for money.

So that it will be found that the fundamental fault in the character of women is that they have no "sense of justice ." This arises from their deficiency in the power of reasoning already referred to, and reflection, but is also partly due to the fact that Nature has not destined them, as the weaker sex, to be dependent on strength but on cunning; this is why they are instinctively crafty, and have an ineradicable tendency to lie.

If a big diamond is cut up into pieces, it immediately loses its value as a whole; or if an army is scattered or divided into small bodies, it loses all its power; and in the same way a great intellect has no more power than an ordinary one as soon as it is interrupted, disturbed, distracted, or diverted; for its superiority entails that it concentrates all its strength on one point and object, just as a concave mirror concentrates all the rays of light thrown upon it. Noisy interruption prevents this concentration. This is why the most eminent intellects have always been strongly averse to any kind of disturbance, interruption and distraction, and above everything to that violent interruption which is caused by noise; other people do not take any particular notice of this sort of thing.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

Truth that has been merely learned is like an artificial limb, a false tooth, a waxen nose; at best, like a nose made out of another's flesh; it adheres to us only because it is put on. But truth acquired by thinking of our own is like a natural limb; it alone really belongs to us. This is the fundamental difference between the thinker and the mere man of learning. The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning.

Reading is merely a surrogate for thinking for yourself; it means letting someone else direct your thoughts. Many books, moreover, serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up, which will of course happen frequently enough even to the best heads; but to banish your own thoughts so as to take up a book is a sin against the holy ghost; it is like deserting untrammeled nature to look at a herbarium or engravings of landscapes.

Buying books would be a good thing if one could also buy the time to read them in: but as a rule the purchase of books is mistaken for the appropriation of their contents.

Jede Trennung gibt einen Vorgeschmack des Todes und jedes Wiedersehen einen Vorgeschmack der Auferstehung. Every parting gives a foretaste of death, every reunion a hint of the resurrection.

We can come to look upon the deaths of our enemies with as much regret as we feel for those of our friends, namely, when we miss their existence as witnesses to our success.

Money is human happiness in the abstract: he, then, who is no longer capable of enjoying human happiness in the concrete devotes his heart entirely to money.

Obstinacy is the result of the will forcing itself into the place of the intellect.

Only a male intellect clouded by the sexual drive could call the stunted, narrow-shouldered, broad-hipped and short-legged sex the fair sex.

In our monogamous part of the world, to marry means to halve one's rights and double one's duties.

A man's face as a rule says more, and more interesting things, than his mouth, for it is a compendium of everything his mouth will ever say, in that it is the monogram of all this man's thoughts and aspirations.

Patriotism, when it wants to make itself felt in the domain of learning, is a dirty fellow who should be thrown out of doors.

Great minds are related to the brief span of time during which they live as great buildings are to a little square in which they stand: you cannot see them in all their magnitude because you are standing too close to them.

People who originally have no means but are ultimately able to earn a great deal, through whatever talents they may possess, almost always come to think that these are permanent capital and that what they gain through them is interest. Accordingly, they do not put aside part of their earnings to form a permanent capital, but spend their money as fast as they earn it. But they are then often reduced to poverty because their earnings decrease or come to an end after their talent, which was of a transitory nature, is exhausted, as happens, for example, in the case of almost all the fine arts; or because it could be brought to bear only under a particular set of circumstances that has ceased to exist.

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.

The fundament upon which all our knowledge and learning rests is the inexplicable.

Do not shorten the morning by getting up late, or waste it in unworthy occupations or in talk; look upon it as the quintessence of life, as to a certain extent sacred. Evening is like old age: we are languid, talkative, silly. Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.

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.

The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.

If you feel irritated by the absurd remarks of two people whose conversation you happen to overhear, you should imagine that you are listening to a dialogue of two fools in a comedy.

How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.

Suicide may also be regarded as an experiment - a question which man puts to Nature, trying to force her to answer. The question is this: What change will death produce in a man's existence and in his insight into the nature of things? It is a clumsy experiment to make; for it involves the destruction of the very consciousness which puts the question and awaits the answer.

Newspapers are the second hand of history. This hand, however, is usually not only of inferior metal to the other hands, it also seldom works properly.

Means at our disposal should be regarded as a bulwark against the many evils and misfortunes that can occur. We should not regard such wealth as a permission or even an obligation to procure for ourselves the pleasures of the world.

That the outer man is a picture of the inner, and the face an expression and revelation of the whole character, is a presumption likely enough in itself, and therefore a safe one to go on; borne out as it is by the fact that people are always anxious to see anyone who has made himself famous .... Photography ... offers the most complete satisfaction of our curiosity.

If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence?

There are two things which make it impossible to believe that this world is the successful work of an all-wise, all-good, and, at the same time, all-powerful Being; firstly, the misery which abounds in it everywhere; and secondly, the obvious imperfection of its highest product, man, who is a burlesque of what he should be.

If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much - and then performed so little.

In early youth, as we contemplate our coming life, we are like children in a theatre before the curtain is raised, sitting there in high spirits and eagerly waiting for the play to begin. It is a blessing that we do not know what is really going to happen. Could we foresee it, there are times when children might seem like innocent prisoners, condemned, not to death, but to life, and as yet all unconscious of what their sentence means.

Hatred comes from the heart; contempt from the head; and neither feeling is quite within our control.
