This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that exercitium arithmeticae occultum nescientis se numerare animi [exercise in arithmetic in which the mind does not know it is counting] which Leibniz took it to be.

The effect of music is so very much more powerful and penetrating than is that of the other arts, for these others speak only of the shadow, but music of the essence.

Just as the witticism brings two very different real objects under one concept, the pun brings two different concepts, by the assistance of accident, under one word.

And now that I have allowed myself the jest to which in this two-sided life hardly any page can be too serious to grant a place, I part with the book with deep seriousness, in the sure hope that sooner or later it will reach those to whom alone it can be addressed; and for the rest, patiently resigned that the same fate should, in full measure, befall it, that in all ages has, to some extent, befallen all knowledge, and especially the weightiest knowledge of the truth, to which only a brief triumph is allotted between the two long periods in which it is condemned as paradoxical or disparaged as trivial. The former fate is also wont to befall its author. But life is short, and truth works far and lives long: let us speak the truth.

Life is a business that does not cover the costs.

Consider the Koran... this wretched book was sufficient to start a world-religion, to satisfy the metaphysical need of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. In this book we find the saddest and poorest form of theism. Much may be lost in translation, but I have not been able to discover in it one single idea of value.

If a person is stupid, we excuse him by saying that he cannot help it; but if we attempted to excuse in precisely the same way the person who is bad, we should be laughed at.

Here the institution that compels is the state, the only purpose of which is to protect individuals from one another and the whole from external enemies. Some German philosophasters of this mercenary age would like to twist it into an institution for education and edification in morality; in the background of this lurks the Jesuitical purpose of eliminating personal freedom and the individual’s personal development in order to make him into a mere cog in a Chinese machine of state and religion. But this is the path by which in the past one has arrived at the inquisitions, burning of heretics, and religious wars; Frederick the Great’s pledge, ‘In my country, each shall be able to tend to his salvation in his own fashion’, indicated that he never wanted to tread that path.

Now if plurality and difference belong only to the appearance-form; if there is but one and the same Entity manifested in all living things: it follows that, when we obliterate the distinction between the ego and the non-ego, we are not the sport of an illusion. Rather are we so, when we maintain the reality of individuation, — a thing the Hindus call Maya, that is, a deceptive vision, a phantasma. The former theory we have found to be the actual source of the phaenomenon of Compassion; indeed Compassion is nothing but its translation into definite expression. This, therefore, is what I should regard as the metaphysical foundation of Ethics, and should describe it as the sense which identifies the ego with the non-ego, so that the individual directly recognises in another his own self, his true and very being. From this standpoint the profoundest teaching of theory pushed to its furthest limits may be shown in the end to harmonise perfectly with the rules of justice and loving-kindness, as exercised; and conversely, it will be clear that practical philosophers, that is, the upright, the beneficent, the magnanimous, do but declare through their acts the same truth as the man of speculation wins by laborious research … He who is morally noble, however deficient in mental penetration, reveals by his conduct the deepest insight, the truest wisdom; and puts to shame the most accomplished and learned genius, if the latter's acts betray that his heart is yet a stranger to this great principle, — the metaphysical unity of life.

The view of things [called Pantheism] … — that all plurality is only apparent, that in the endless series of individuals, passing simultaneously and successively into and out of life, generation after generation, age after age, there is but one and the same entity really existing, which is present and identical in all alike; — this theory … may be carried back to the remotest antiquity. It is the alpha and omega of the oldest book in the world, the sacred Vedas, whose dogmatic part, or rather esoteric teaching, is found in the Upanishads. There, in almost every page this profound doctrine lies enshrined; with tireless repetition, in countless adaptations, by many varied parables and similes it is expounded and inculcated. That such was, moreover, the fount whence Pythagoras drew his wisdom, cannot be doubted … That it formed practically the central point in the whole philosophy of the Eleatic School, is likewise a familiar fact. Later on, the New Platonists were steeped in the same … In the ninth century we find it unexpectedly appearing in Europe. It kindles the spirit of no less a divine than Johannes Scotus Erigena, who endeavours to clothe it with the forms and terminology of the Christian religion. Among the Mohammedans we detect it again in the rapt mysticism of the Sufi. In the West Giordano Bruno cannot resist the impulse to utter it aloud; but his reward is a death of shame and torture. And at the same time we find the Christian Mystics losing themselves in it, against their own will and intention, whenever and wherever we read of them! Spinoza's name is identified with it.

My basis is supported by the authority of the greatest moralist of modern times; for such, undoubtedly, J. J. Rousseau is,—that profound reader of the human heart, who drew his wisdom not from books, but from life, and intended his doctrine not for the professorial chair, but for humanity; he, the foe of all prejudice, the foster-child of nature, whom alone she endowed with the gift of being able to moralise without tediousness, because he hit the truth and stirred the heart.

Europeans are awakening more and more to a sense that beasts have rights, in proportion as the strange notion is being gradually overcome and outgrown, that the animal kingdom came into existence solely for the benefit and pleasure of man. This view, with the corollary that non-human living creatures are to be regarded merely as things, is at the root of the rough and altogether reckless treatment of them, which obtains in the West.

Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.

It is asserted that beasts have no rights; the illusion is harboured that our conduct, so far as they are concerned, has no moral significance, or, as it is put in the language of these codes, that "there are no duties to be fulfilled towards animals." Such a view is one of revolting coarseness, a barbarism of the West, whose source is Judaism. In philosophy, however, it rests on the assumption, despite all evidence to the contrary, of the radical difference between man and beast,—a doctrine which, as is well known, was proclaimed with more trenchant emphasis by Descartes than by any one else: it was indeed the necessary consequence of his mistakes.

Boundless compassion for all living beings is the surest and most certain guarantee of pure moral conduct, and needs no casuistry. Whoever is filled with it will assuredly injure no one, do harm to no one, encroach on no man's rights; he will rather have regard for every one, forgive every one, help every one as far as he can, and all his actions will bear the stamp of justice and loving-kindness. … In former times the English plays used to finish with a petition for the King. The old Indian dramas close with these words: "May all living beings be delivered from pain." Tastes differ; but in my opinion there is no more beautiful prayer than this.

Thus, because Christian morals leave animals out of consideration … therefore in philosophical morals they are of course at once outlawed; they are merely "things," simply means to ends of any sort; and so they are good for vivisection, for deer-stalking, bull-fights, horse-races, etc., and they may be whipped to death as they struggle along with heavy quarry carts. Shame on such a morality … which fails to recognize the Eternal Reality immanent in everything that has life, and shining forth with inscrutable significance from all eyes that see the sun!

The world is idea.This truth is by no means new. It was implicitly involved in the sceptical reflections from which Descartes started. Berkeley, however, was the first who distinctly enunciated it, and by this he has rendered a permanent service to philosophy, even though the rest of his teaching should not endure. Kant's primary mistake was the neglect of this principle... How early again this truth was recognised by the wise men of India, appearing indeed as the fundamental tenet of the Vedânta philosophy ascribed to Vyasa, is pointed out by Sir William Jones in the last of his essays: "On the philosophy of the Asiatics"...

We, on the contrary, now send to the Brahmans English clergymen and evangelical linen-weavers, in order out of sympathy to put them right, and to point out to them that they are created out of nothing, and that they ought to be grateful and pleased about it. But it is Just the same as if we fired a bullet at a cliff. " In India, our religions wIll never at any time take root; the ancient wisdom of the human race will not be supplanted by the events in Galilee. On the contrary, Indian Wisdom flows back to Europe, and will produce a fundamental change in our knowledge and thought.

In every page of David Hume, there is more to be learned than from Hegel's, Herbart's and Schleiermacher's complete philosophical works. - vol. II, p. 582 (as cited on p. 177 of Schopenhauer: A Biography)

Whoever heard me assert that the grey cat playing just now in the yard is the same one that did jumps and tricks there five hundred years ago will think whatever he likes of me, but it is a stranger form of madness to imagine that the present-day cat is fundamentally an entirely different one.

...this our world, which is so real, with all its suns and milky ways is—nothing.

At the age of five years to enter a spinning-cotton or other factory, and from that time forth to sit there daily, first ten, then twelve, and ultimately fourteen hours, performing the same mechanical labour, is to purchase dearly the satisfaction of drawing breath. But this is the fate of millions, and that of millions more is analogous to it.

All religions promise a reward for excellences of the will or heart, but none for excellences of the head or understanding.

The philosophy of Kant, then, is the only philosophy with which a thorough acquaintance is directly presupposed in what we have to say here. But if, besides this, the reader has lingered in the school of the divine Plato, he will be so much the better prepared to hear me, and susceptible to what I say. And if, indeed, in addition to this he is a partaker of the benefit conferred by the Vedas, the access to which, opened to us through the Upanishads, is in my eyes the greatest advantage which this still young century enjoys over previous ones, because I believe that the influence of the Sanscrit literature will penetrate not less deeply than did the revival of Greek literature in the fifteenth century: if, I say, the reader has also already received and assimilated the sacred, ancient Indian wisdom, then is he best of all prepared to hear what I have to say to him. My work will not speak to him, as to many others, in a strange and even hostile tongue; for, if it does not sound too vain, I might express the opinion that each one of the individual and disconnected aphorisms which make up the Upanishads may be deduced as a consequence from the thought I am going to impart, though the converse, that my thought is to be found in the Upanishads, is by no means the case.

You are not an evil human; you are not without intellect and education; you have everything that could make you a credit to human society. Moreover, I am acquainted with your heart and know that few are better, but you are nevertheless irritating and unbearable, and I consider it most difficult to live with you.All of your good qualities become obscured by your super-cleverness and are made useless to the world merely because of your rage at wanting to know everything better than others; of wanting to improve and master what you cannot command. With this you embitter the people around you, since no one wants to be improved or enlightened in such a forceful way, least of all by such an insignificant individual as you still are; no one can tolerate being reproved by you, who also still show so many weaknesses yourself, least of all in your adverse manner, which in oracular tones, proclaims this is so and so, without ever supposing an objection.If you were less like you, you would only be ridiculous, but thus as you are, you are highly annoying.

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

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.

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.

As my own father was sick, and miserably tied to his invalid's chair, he would have been abandoned had not an old servant performed for him a so-called service of love. My mother gave parties while he was perishing in solitude, and amused herself while he was suffering bitter agonies

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?

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

The heavy armor becomes the light dress of childhood; the pain is brief, the joy unending.

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.'

Noise is the most impertinent of all forms of interruption. It is not only an interruption, but also a disruption of thought.

There are 80,000 prostitutes in London alone and what are they, if not bloody sacrifices on the altar of monogamy?

Dissimulation is innate in woman, and almost as much a quality of the stupid as of the clever.

Every parting gives a foretaste of death; every coming together again a foretaste of the resurrection.

Every man takes the limits of his own field of vision for the limits of the world.

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".

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.

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.

Criminal history shows us how many torturers of men, and murderers, have first been torturers of animals. The manner in which a nation in the aggregate treats animals, is one chief measure of its real civilization. The Latin races, as we know, come forth badly from this examination; we Germans, not half well enough. Buddhism has done more in this direction than Christianity, and Schopenhauer more than all ancient and modern philosophers together. The warm sympathy with sentient Nature which pervades all the writings of Schopenhauer, is one of the most pleasing aspects of his thoroughly intellectual, yet often unhealthy and unprofitable philosophy.

We are struck by the psychological force and even fierceness with which he reveals the deepest recesses of the human heart.

He speaks to me as no other philosopher does, direct and in his own human voice, a fellow spirit, a penetratingly perceptive friend, with a hand on my elbow and a twinkle in his eye. Although I frequently do not agree with what he says, I always listen to him.

One who believes that the pain in the world outweighs the joy, and expresses that unhappy conviction, only adds to the pain. Schopenhauer is an enemy to the race. Even if he earnestly believed that this is the most wretched of possible worlds, he should not promulgate a doctrine which robs men of the incentive to fight with circumstance. If Life gave him ashes for bread, it was his fault. Life is a fair field, and the right will prosper if we stand by our guns.

He was the first to speak of the suffering of the world, which visibly and glaringly surrounds us, and of confusion, passion, evil — all those things which the [other philosophers] hardly seemed to notice and always tried to resolve into all-embracing harmony and comprehensiblility. Here at last was a philosopher who had the courage to see that all was not for the best in the fundaments of the universe.

Keats, entirely a stranger to error, could believe that the nightingale enchanting him was the same one Ruth heard amid the alien corn of Bethlehem in Judah; Stevenson posits a single bird that consumes the centuries: "the nightingale that devours time." Schopenhauer — impassioned, lucid Schopenhauer — provides a reason: the pure corporeal immediacy in which animals live, oblivious to death and memory. He then adds, not without a smile: Whoever hears me assert that the grey cat playing just now in the yard is the same one that did jumps and tricks there five hundred years ago will think whatever he likes of me, but it is a stranger form of madness to imagine that the present-day cat is fundamentally an entirely different one.
