Arthur Schopenhauer (/ˈʃoʊpənˌhaʊ.ər/; German: [ˈaɐ̯tʊɐ̯ ˈʃoːpm̩ˌhaʊ̯ɐ]; 22 February 1788 – 21 September 1860) was a German philosopher. He is best known for his 1818 work The World as Will and Representation (expanded in 1844), wherein he characterizes the phenomenal world as the product of a blind and insatiable metaphysical will. Proceeding from the transcendental idealism of Immanuel Kant, Schopenhauer developed an atheistic metaphysical and ethical system that has been described as an exemplary manifestation of philosophical pessimism, rejecting the contemporaneous post-Kantian philosophies of German idealism. Schopenhauer was among the first thinkers in Western philosophy to share and affirm significant tenets of Eastern philosophy (e.g., asceticism, the world-as-appearance), having initially arrived at similar conclusions as the result of his own philosophical work.
Though his work failed to garner substantial attention during his life, Schopenhauer has had a posthumous impact across various disciplines, including philosophy, literature, and science. His writing on aesthetics, morality, and psychology would exert important influence on thinkers and artists throughout the 19th and 20th centuries. Those who have cited his influence include Friedrich Nietzsche, Richard Wagner, Leo Tolstoy, Ludwig Wittgenstein, Erwin Schrödinger, Otto Rank, Gustav Mahler, Joseph Campbell, Albert Einstein, Carl Jung, Thomas Mann, Emile Zola, George Bernard Shaw, Jorge Luis Borges and Samuel Beckett.

Schopenhauer was born on 22 February 1788, in the city of Danzig (then part of the Polish–Lithuanian Commonwealth; present day Gdańsk, Poland) on Heiligegeistgasse (known in the present day as Św. Ducha 47), the son of Johanna Schopenhauer (née Trosiener) and Heinrich Floris Schopenhauer, both descendants of wealthy German patrician families. When Danzig became part of Prussia in 1793, Heinrich moved to Hamburg, although his firm continued trading in Danzig. As early as 1799, Arthur started playing the flute.:30 In 1805, Schopenhauer's father died, possibly by suicide. Arthur endured two long years of drudgery as a merchant in honor of his dead father, but his mother soon moved with his sister Adele to Weimar—then the centre of German literature—to pursue her writing career. He dedicated himself wholly to studies at the Gotha gymnasium (Gymnasium illustre zu Gotha) in Saxe-Gotha-Altenburg, but left in disgust after seeing one of the masters lampooned.
By that time, Johanna Schopenhauer had already opened her famous salon, and Arthur was not compatible with what he considered its vain and ceremonious ways. He was also disgusted by the ease with which his mother had forgotten his father's memory. He left to become a student at the University of Göttingen in 1809. There he studied metaphysics and psychology under Gottlob Ernst Schulze, the author of Aenesidemus, who advised him to concentrate on Plato and Immanuel Kant. In Berlin, from 1811 to 1812, he had attended lectures by the prominent post-Kantian philosopher Johann Gottlieb Fichte and the theologian Friedrich Schleiermacher.
Schopenhauer had a notably strained relationship with his mother Johanna. He wrote his first book, On the Fourfold Root of the Principle of Sufficient Reason, while at university. His mother informed him that the book was incomprehensible and it was unlikely that anyone would ever buy a copy. In a fit of temper Arthur Schopenhauer told her that his work would be read long after the "rubbish" she wrote would have been totally forgotten. In fact, although they considered her novels of dubious quality, the Brockhaus publishing firm held her in high esteem because they consistently sold well. Hans Brockhaus later recalled that, when she brought them some of her son's work, his predecessors "saw nothing in this manuscript, but wanted to please one of our best-selling authors by publishing her son's work. We published more and more of her son Arthur's work and today nobody remembers Johanna, but her son's works are in steady demand and contribute to Brockhaus'[s] reputation." He kept large portraits of the pair in his office in Leipzig for the edification of his new editors.
In 1814, Schopenhauer began his seminal work The World as Will and Representation (Die Welt als Wille und Vorstellung). He finished it in 1818 and Brockhaus published it that December. In Dresden in 1819, Schopenhauer fathered, with a servant, an illegitimate daughter who was born and died the same year. In 1820, Schopenhauer became a lecturer at the University of Berlin. He scheduled his lectures to coincide with those of the famous philosopher G. W. F. Hegel, whom Schopenhauer described as a "clumsy charlatan". However, only five students turned up to Schopenhauer's lectures, and he dropped out of academia. A late essay, On University Philosophy, expressed his resentment towards the work conducted in academies.
While in Berlin, Schopenhauer was named as a defendant in a lawsuit initiated by a woman named Caroline Marquet. She asked for damages, alleging that Schopenhauer had pushed her. According to Schopenhauer's court testimony, she deliberately annoyed him by raising her voice while standing right outside his door. Marquet alleged that the philosopher had assaulted and battered her after she refused to leave his doorway. Her companion testified that she saw Marquet prostrate outside his apartment. Because Marquet won the lawsuit, Schopenhauer made payments to her for the next twenty years. When she died, he wrote on a copy of her death certificate, Obit anus, abit onus ("The old woman dies, the burden is lifted"). In 1819 the fortunes of his mother and sister, and himself, were threatened by the failure of the firm in Danzig in which his father had been a director and shareholder. His sister accepted a compromise compensation package of 70 per cent, but Schopenhauer angrily refused this, and eventually recovered 9400 thalers.
In 1821, he fell in love with nineteen-year-old opera singer, Caroline Richter (called Medon), and had a relationship with her for several years, but did not marry her. When he was forty-three years old, he took interest in seventeen-year-old Flora Weiss but she rejected him as recorded in her diary.
In 1831, a cholera epidemic broke out in Berlin and Schopenhauer left the city. Schopenhauer settled permanently in Frankfurt in 1833, where he remained for the next twenty-seven years, living alone except for a succession of pet poodles named Atman and Butz. The numerous notes that he made during these years, amongst others on aging, were published posthumously under the title Senilia. Schopenhauer had a robust constitution, but in 1860 his health began to deteriorate. He died of pulmonary-respiratory failure, on 21 September 1860 while sitting at home on his couch. He was 72.
Schopenhauer saw his philosophy as a continuation of that of Kant, and used the results of his epistemological investigations, that is, transcendental idealism, as starting point for his own:
My philosophy is founded on that of Kant, and therefore presupposes a thorough knowledge of it. Kant's teaching produces in the mind of everyone who has comprehended it a fundamental change which is so great that it may be regarded as an intellectual new-birth. It alone is able really to remove the inborn realism which proceeds from the original character of the intellect, which neither Berkeley nor Malebranche succeed in doing, for they remain too much in the universal, while Kant goes into the particular, and indeed in a way that is quite unexampled both before and after him, and which has quite a peculiar, and, we might say, immediate effect upon the mind in consequence of which it undergoes a complete undeception, and forthwith looks at all things in another light. Only in this way can anyone become susceptible to the more positive expositions which I have to give.
Kant had argued the empirical world is merely a complex of appearances whose existence and connection occur only in our representations. Schopenhauer reiterates this in the first sentence of his main work: "The world is my representation." We do not draw empirical laws from nature, but prescribe them to it.
Schopenhauer praises Kant for his distinction between appearance and the things-in-themselves that appear, whereas the general consensus in German Idealism was that this was the weakest spot of Kant’s theory, since according to Kant causality can find application on objects of experience only, and consequently, things-in-themselves cannot be the cause of appearances, as Kant argued. The inadmissibility of this reasoning was also acknowledged by Schopenhauer. He insisted that this distinction was a true conclusion, drawn from false premises.
In November 1813 Goethe invited Schopenhauer for research on his Theory of Colours. Although Schopenhauer considered colour theory to be a minor matter, he accepted the invitation out of admiration for Goethe. Nevertheless, these investigations led him to his most important discovery in epistemology: finding a demonstration for the a priori nature of causality.
Kant openly admitted that it was Hume's skeptical assault on causality that motivated the critical investigations of Critique of Pure Reason. In it, he gives an elaborate proof to show that causality is given a priori. After G.E. Schulze had made it plausible that Kant had not disproven Hume’s skepticism, it was up to those loyal to the project of Kant to prove this important matter.
The difference between the approach of Kant and Schopenhauer was this: Kant simply declared that the empirical content of perception is "given" to us from outside, an expression with which Schopenhauer often expressed his dissatisfaction. He, on the other hand, was occupied with: how do we get this empirical content of perception; how is it possible to comprehend subjective sensations limited to my skin as the objective perception of things that lie outside of me?
The sensations in the hand of a man born blind, on feeling an object of cubic shape, are quite uniform and the same on all sides and in every direction: the edges, it is true, press upon a smaller portion of his hand, still nothing at all like a cube is contained in these sensations. His Understanding, however, draws the immediate and intuitive conclusion from the resistance felt, that this resistance must have a cause, which then presents itself through that conclusion as a hard body; and through the movements of his arms in feeling the object, while the hand's sensation remains unaltered, he constructs the cubic shape in Space. If the representation of a cause and of Space, together with their laws, had not already existed within him, the image of a cube could never have proceeded from those successive sensations in his hand.
Causality is therefore not an empirical concept drawn from objective perceptions, but objective perception presupposes knowledge of causality. Hereby Hume's skepticism is disproven.
By this intellectual operation, comprehending every effect in our sensory organs as having an external cause, the external world arises. With vision, finding the cause is essentially simplified due light acting in straight lines. We are seldom conscious of the process, that interprets the double sensation in both eyes as coming from one object; that turns the upside down impression; and that adds depth to make from the planimetrical data stereometrical perception with distance between objects.
Schopenhauer stresses the importance of the intellectual nature of perception, the senses furnish the raw material by which the intellect produces the world as representation. He set out his theory of perception for the first time in On Vision and Colors, and in the subsequent editions of Fourfold Root an extensive exposition is given in § 21.
Schopenhauer developed a system which is known as metaphysical voluntarism.
The kernel and chief point of my doctrine, its Metaphysic proper, is this, that what Kant opposed as thing-in-itself to mere appearance (called more decidedly by me "representation") and what he held to be absolutely unknowable, that this thing-in-itself, I say, this substratum of all appearances, and therefore of the whole of Nature, is nothing but what we know directly and intimately and find within ourselves as will; that accordingly, this will, far from being inseparable from, and even a mere result of, knowledge, differs radically and entirely from, and is quite independent of, knowledge, which is secondary and of later origin; and can consequently subsist and manifest itself without knowledge: that this will, being the one and only thing-in-itself, the sole truly real, primary, metaphysical thing in a world in which everything else is only appearance, i.e., mere representation, gives all things, whatever they may be, the power to exist and to act; ... is absolutely identical with the will we find within us and know as intimately as we can know any thing; that, on the other hand, knowledge with its substratum, the intellect, is a merely secondary phenomenon, differing completely from the will, only accompanying its higher degrees of objectification and not essential to it; ... that we are never able therefore to infer absence of will from absence of knowledge.— On the Will in Nature, Introduction
For Schopenhauer, human desire was futile, illogical, directionless, and, by extension, so was all human action in the world. Einstein paraphrased his views as follows: "Man can indeed do what he wants, but he cannot will what he wants." In this sense, he adhered to the Fichtean principle of idealism: "The world is for a subject." This idealism so presented, immediately commits it to an ethical attitude, unlike the purely epistemological concerns of Descartes and Berkeley. To Schopenhauer, the Will is a blind force that controls not only the actions of individual, intelligent agents, but ultimately all observable phenomena—an evil to be terminated via mankind's duties: asceticism and chastity. He is credited with one of the most famous opening lines of philosophy: "The world is my representation." Friedrich Nietzsche was greatly influenced by this idea of Will, although he eventually rejected it.
For Schopenhauer, human desiring, "willing", and craving cause suffering or pain. A temporary way to escape this pain is through aesthetic contemplation (a method comparable to Zapffe's "Sublimation"). Aesthetic contemplation allows one to escape this pain—albeit temporarily—because it stops one perceiving the world as mere presentation. Instead, one no longer perceives the world as an object of perception (therefore as subject to the Principle of Sufficient Grounds; time, space and causality) from which one is separated; rather one becomes one with that perception: "one can thus no longer separate the perceiver from the perception" (The World as Will and Representation, section 34). From this immersion with the world one no longer views oneself as an individual who suffers in the world due to one's individual will but, rather, becomes a "subject of cognition" to a perception that is "Pure, will-less, timeless" (section 34) where the essence, "ideas", of the world are shown. Art is the practical consequence of this brief aesthetic contemplation as it attempts to depict one's immersion with the world, thus tries to depict the essence/pure ideas of the world. Music, for Schopenhauer, was the purest form of art because it was the one that depicted the will itself without it appearing as subject to the Principle of Sufficient Grounds, therefore as an individual object. According to Daniel Albright, "Schopenhauer thought that music was the only art that did not merely copy ideas, but actually embodied the will itself".
He deemed music a timeless, universal language comprehended everywhere, that can imbue global enthusiasm, if in possession of a significant melody.
Schopenhauer's realist views on mathematics are evident in his criticism of the contemporary attempts to prove the parallel postulate in Euclidean geometry. Writing shortly before the discovery of hyperbolic geometry demonstrated the logical independence of the axiom—and long before the general theory of relativity revealed that it does not necessarily express a property of physical space—Schopenhauer criticized mathematicians for trying to use indirect concepts to prove what he held to be directly evident from perception.
The Euclidean method of demonstration has brought forth from its own womb its most striking parody and caricature in the famous controversy over the theory of parallels, and in the attempts, repeated every year, to prove the eleventh axiom (also known as the fifth postulate). The axiom asserts, and that indeed through the indirect criterion of a third intersecting line, that two lines inclined to each other (for this is the precise meaning of "less than two right angles"), if produced far enough, must meet. Now this truth is supposed to be too complicated to pass as self-evident, and therefore needs a proof; but no such proof can be produced, just because there is nothing more immediate.
Throughout his writings, Schopenhauer criticized the logical derivation of philosophies and mathematics from mere concepts, instead of from intuitive perceptions.
In fact, it seems to me that the logical method is in this way reduced to an absurdity. But it is precisely through the controversies over this, together with the futile attempts to demonstrate the directly certain as merely indirectly certain, that the independence and clearness of intuitive evidence appear in contrast with the uselessness and difficulty of logical proof, a contrast as instructive as it is amusing. The direct certainty will not be admitted here, just because it is no merely logical certainty following from the concept, and thus resting solely on the relation of predicate to subject, according to the principle of contradiction. But that eleventh axiom regarding parallel lines is a synthetic proposition a priori, and as such has the guarantee of pure, not empirical, perception; this perception is just as immediate and certain as is the principle of contradiction itself, from which all proofs originally derive their certainty. At bottom this holds good of every geometrical theorem ...
Although Schopenhauer could see no justification for trying to prove Euclid's parallel postulate, he did see a reason for examining another of Euclid's axioms.
It surprises me that the eighth axiom, "Figures that coincide with one another are equal to one another", is not rather attacked. For "coinciding with one another" is either a mere tautology, or something quite empirical, belonging not to pure intuition or perception, but to external sensuous experience. Thus it presupposes mobility of the figures, but matter alone is movable in space. Consequently, this reference to coincidence with one another forsakes pure space, the sole element of geometry, in order to pass over to the material and empirical.
The task of ethics is not to prescribe moral actions that ought to be done, but to investigate moral actions. Philosophy is always theoretical: its task to explain what is given.
According to Kant's teaching of transcendental idealism, space and time are forms of our sensibility due which the phenomena appear in multiplicity. Reality in itself is free from all multiplicity, not in the sense that an object is one, but that it is outside the possibility of multiplicity. From this follows that two individuals, though they appear as distinct, are in-themselves not distinct.
The appearances are entirely subordinated to the principle of sufficient reason. The egoistic individual who focuses its aims completely on his own interests has therefore to deal with empirical laws as good as he can.
What is relevant for ethics are individuals who can act against their own self-interest. If we take for example a man who suffers when he sees his fellow men living in poverty, and consequently uses a significant part of his income to support their needs instead his own pleasures, then the simplest way to describe this is that he makes less distinction between himself and others than is usually made.
Regarding how the things appear to us, the egoist is right to assert the gap between two individuals, but the altruist experiences the sufferings of others as his own. In the same way a compassionate man cannot hurt animals, though they appear as distinct from himself.
What motivates the altruist is compassion. The sufferings of others is for him not a cold matter to which he is indifferent, but he feels connected to all beings. Compassion is thus the basis of morality.
Schopenhauer calls the principle due which multiplicity appears the principium individuationis. When we behold nature we see that it is a cruel battle for existence, individual manifestations of the will can maintain themselves at expense of others only, the will, as only thing which exists, has no other option but devouring itself in order to experience pleasure. This is a fundamental characteristic of the will, which cannot be circumvented.
Tormenter and tormented are one. Suffering is the moral retribution of our attachment to pleasure. Schopenhauer deemed that this truth was expressed by Christian dogma of original sin and in Eastern religions with the dogma of rebirth.
He who sees through the principium individuationis and comprehends suffering in general as his own, will see suffering everywhere, and instead of using all his force to fight for the happiness of his individual manifestation, he will abhor life itself, of which he knows how inseparably it is connected with suffering. A happy individual life midst of a world of suffering is for him like beggar who dreams one night that he is a king.
Those who have experienced this intuitive knowledge can no longer affirm life, but will exhibit asceticism and quietism, meaning that they are no longer sensitive to motives, are not concerned about their individual welfare, and accept the evil others inflect on them without resisting. They welcome poverty, do not seek nor flee death.
Human life is a ceaseless struggle for satisfaction, and instead of renewing this contract, the ascetic breaks it. It matters little whether these ascetics adhered the dogmata of Christianity or Dharmic religions, since their way of living is the result of intuitive knowledge.
The Christian mystic and the teacher of the Vedanta philosophy agree in this respect also, they both regard all outward works and religious exercises as superfluous for him who has attained to perfection. So much agreement in the case of such different ages and nations is a practical proof that what is expressed here is not, as optimistic dullness likes to assert, an eccentricity and perversity of the mind, but an essential side of human nature, which only appears so rarely because of its excellence.
Schopenhauer referred to asceticism as the denial of the will to live.
Philosophers have not traditionally been impressed by the tribulations of sex, but Schopenhauer addressed it and related concepts forthrightly:
... one ought rather to be surprised that a thing [sex] which plays throughout so important a part in human life has hitherto practically been disregarded by philosophers altogether, and lies before us as raw and untreated material.
He named a force within man that he felt took invariable precedence over reason: the Will to Live or Will to Life (Wille zum Leben), defined as an inherent drive within human beings, and indeed all creatures, to stay alive; a force that inveigles us into reproducing.
Schopenhauer refused to conceive of love as either trifling or accidental, but rather understood it as an immensely powerful force that lay unseen within man's psyche, guaranteeing the quality of the human race:
The ultimate aim of all love affairs ... is more important than all other aims in man's life; and therefore it is quite worthy of the profound seriousness with which everyone pursues it. What is decided by it is nothing less than the composition of the next generation ...
It has often been argued that Schopenhauer's thoughts on sexuality foreshadowed the theory of evolution, a claim which seems to have been met with satisfaction by Darwin as he included a quote of the German philosopher in his Descent of Man after having read such a claim. This has also been noted about Freud's concepts of the libido and the unconscious mind, and evolutionary psychology in general.
Schopenhauer's politics were, for the most part, an echo of his system of ethics (the latter being expressed in Die beiden Grundprobleme der Ethik, available in English as two separate books, On the Basis of Morality and On the Freedom of the Will). Ethics also occupies about one quarter of his central work, The World as Will and Representation.
In occasional political comments in his Parerga and Paralipomena and Manuscript Remains, Schopenhauer described himself as a proponent of limited government. What was essential, he thought, was that the state should "leave each man free to work out his own salvation", and so long as government was thus limited, he would "prefer to be ruled by a lion than one of [his] fellow rats"—i.e., by a monarch, rather than a democrat. Schopenhauer shared the view of Thomas Hobbes on the necessity of the state, and of state action, to check the destructive tendencies innate to our species. He also defended the independence of the legislative, judicial and executive branches of power, and a monarch as an impartial element able to practise justice (in a practical and everyday sense, not a cosmological one). He declared monarchy as "that which is natural to man" for "intelligence has always under a monarchical government a much better chance against its irreconcilable and ever-present foe, stupidity" and disparaged republicanism as "unnatural as it is unfavourable to the higher intellectual life and the arts and sciences".
Schopenhauer, by his own admission, did not give much thought to politics, and several times he writes proudly of how little attention he had paid "to political affairs of [his] day". In a life that spanned several revolutions in French and German government, and a few continent-shaking wars, he did indeed maintain his aloof position of "minding not the times but the eternities". He wrote many disparaging remarks about Germany and the Germans. A typical example is, "For a German it is even good to have somewhat lengthy words in his mouth, for he thinks slowly, and they give him time to reflect."
Schopenhauer attributed civilizational primacy to the northern "white races" due to their sensitivity and creativity (except for the ancient Egyptians and Hindus, whom he saw as equal):
The highest civilization and culture, apart from the ancient Hindus and Egyptians, are found exclusively among the white races; and even with many dark peoples, the ruling caste or race is fairer in colour than the rest and has, therefore, evidently immigrated, for example, the Brahmans, the Incas, and the rulers of the South Sea Islands. All this is due to the fact that necessity is the mother of invention because those tribes that emigrated early to the north, and there gradually became white, had to develop all their intellectual powers and invent and perfect all the arts in their struggle with need, want and misery, which in their many forms were brought about by the climate. This they had to do in order to make up for the parsimony of nature and out of it all came their high civilization.
Despite this, he was adamantly against differing treatment of races, was fervently anti-slavery, and supported the abolitionist movement in the United States. He describes the treatment of "[our] innocent black brothers whom force and injustice have delivered into [the slave-master's] devilish clutches" as "belonging to the blackest pages of mankind's criminal record".
Schopenhauer additionally maintained a marked metaphysical and political anti-Judaism. Schopenhauer argued that Christianity constituted a revolt against what he styled the materialistic basis of Judaism, exhibiting an Indian-influenced ethics reflecting the Aryan-Vedic theme of spiritual "self-conquest". This he saw as opposed to what he held to be the ignorant drive toward earthly utopianism and superficiality of a worldly "Jewish" spirit:
While all other religions endeavor to explain to the people by symbols the metaphysical significance of life, the religion of the Jews is entirely immanent and furnishes nothing but a mere war-cry in the struggle with other nations.
The State, Schopenhauer claimed, punishes criminals to prevent future crimes. It does so by placing "beside every possible motive for committing a wrong a more powerful motive for leaving it undone, in the inescapable punishment. Accordingly, the criminal code is as complete a register as possible of counter-motives to all criminal actions that can possibly be imagined ..." He claimed this doctrine was not original to him. Previously, it appeared in the writings of Plato, Seneca, Hobbes, Pufendorf, and Anselm Feuerbach.
In Schopenhauer's 1851 essay On Women, he expressed his opposition to what he called "Teutonico-Christian stupidity" of reflexive unexamined reverence ("abgeschmackten Weiberveneration") for the female. Schopenhauer wrote that "Women are directly fitted for acting as the nurses and teachers of our early childhood by the fact that they are themselves childish, frivolous and short-sighted." He opined that women are deficient in artistic faculties and sense of justice, and expressed opposition to monogamy. Indeed, Rodgers and Thompson in Philosophers Behaving Badly call Schopenhauer "a misogynist without rival in ... Western philosophy". He claimed that "woman is by nature meant to obey". The essay does give some compliments, however: that "women are decidedly more sober in their judgment than [men] are", and are more sympathetic to the suffering of others.
Schopenhauer's controversial writings have influenced many, from Friedrich Nietzsche to nineteenth-century feminists. Schopenhauer's biological analysis of the difference between the sexes, and their separate roles in the struggle for survival and reproduction, anticipates some of the claims that were later ventured by sociobiologists and evolutionary psychologists.
When the elderly Schopenhauer sat for a sculpture portrait by the Prussian sculptor Elisabet Ney in 1859, he was much impressed by the young woman's wit and independence, as well as by her skill as a visual artist. After his time with Ney, he told Richard Wagner's friend Malwida von Meysenbug, "I have not yet spoken my last word about women. I believe that if a woman succeeds in withdrawing from the mass, or rather raising herself above the mass, she grows ceaselessly and more than a man."
Schopenhauer viewed personality and intellect as being inherited. He quotes Horace's saying, "From the brave and good are the brave descended" (Odes, iv, 4, 29) and Shakespeare's line from Cymbeline, "Cowards father cowards, and base things sire base" (IV, 2) to reinforce his hereditarian argument. Mechanistically, Schopenhauer believed that a person inherits his level of intellect through his mother, and personal character through one's father. This belief in heritability of traits informed Schopenhauer's view of love – placing it at the highest level of importance. For Schopenhauer the "final aim of all love intrigues, be they comic or tragic, is really of more importance than all other ends in human life. What it all turns upon is nothing less than the composition of the next generation. ... It is not the weal or woe of any one individual, but that of the human race to come, which is here at stake." This view of the importance for the species of whom we choose to love was reflected in his views on eugenics or good breeding. Here Schopenhauer wrote:
With our knowledge of the complete unalterability both of character and of mental faculties, we are led to the view that a real and thorough improvement of the human race might be reached not so much from outside as from within, not so much by theory and instruction as rather by the path of generation. Plato had something of the kind in mind when, in the fifth book of his Republic, he explained his plan for increasing and improving his warrior caste. If we could castrate all scoundrels and stick all stupid geese in a convent, and give men of noble character a whole harem, and procure men, and indeed thorough men, for all girls of intellect and understanding, then a generation would soon arise which would produce a better age than that of Pericles.
In another context, Schopenhauer reiterated his eugenic thesis: "If you want Utopian plans, I would say: the only solution to the problem is the despotism of the wise and noble members of a genuine aristocracy, a genuine nobility, achieved by mating the most magnanimous men with the cleverest and most gifted women. This proposal constitutes my Utopia and my Platonic Republic." Analysts (e.g., Keith Ansell-Pearson) have suggested that Schopenhauer's anti-egalitarianist sentiment and his support for eugenics influenced the neo-aristocratic philosophy of Friedrich Nietzsche, who initially considered Schopenhauer his mentor.
As a consequence of his monistic philosophy, Schopenhauer was very concerned about the welfare of animals. For him, all individual animals, including humans, are essentially the same, being phenomenal manifestations of the one underlying Will. The word "will" designated, for him, force, power, impulse, energy, and desire; it is the closest word we have that can signify both the real essence of all external things and also our own direct, inner experience. Since every living thing possesses will, then humans and animals are fundamentally the same and can recognize themselves in each other. For this reason, he claimed that a good person would have sympathy for animals, who are our fellow sufferers.
Compassion for animals is intimately associated with goodness of character, and it may be confidently asserted that he who is cruel to living creatures cannot be a good man.— On the basis of morality, § 19</ref>
Nothing leads more definitely to a recognition of the identity of the essential nature in animal and human phenomena than a study of zoology and anatomy.— On the basis of morality, chapter 8
The assumption that animals are without rights and the illusion that our treatment of them has no moral significance is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality.— On the basis of morality, chapter 8
In 1841, he praised the establishment, in London, of the Society for the Prevention of Cruelty to Animals, and also the Animals' Friends Society in Philadelphia. Schopenhauer even went so far as to protest against the use of the pronoun "it" in reference to animals because it led to the treatment of them as though they were inanimate things. To reinforce his points, Schopenhauer referred to anecdotal reports of the look in the eyes of a monkey who had been shot and also the grief of a baby elephant whose mother had been killed by a hunter.
In the third, expanded edition of The World as Will and Representation (1859), Schopenhauer added an appendix to his chapter on the Metaphysics of Sexual Love. He also wrote that homosexuality did have the benefit of preventing ill-begotten children. Concerning this, he stated that "the vice we are considering appears to work directly against the aims and ends of nature, and that in a matter that is all important and of the greatest concern to her it must in fact serve these very aims, although only indirectly, as a means for preventing greater evils".
He wrote that only those who were too old or too young to reproduce strong, healthy children would resort to pederasty (Schopenhauer considered pederasty in itself a vice). Shrewdly anticipating the interpretive distortion, on the part of the popular mind, of his attempted scientific explanation of pederasty as personal advocacy (when he had otherwise described the act, in terms of spiritual ethics, as an "objectionable aberration"), Schopenhauer sarcastically concludes the appendix with the statement that "by expounding these paradoxical ideas, I wanted to grant to the professors of philosophy a small favour, for they are very disconcerted by the ever-increasing publicization of my philosophy which they so carefully concealed. I have done so by giving them the opportunity of slandering me by saying that I defend and commend pederasty."
Schopenhauer read the Latin translation of the ancient Hindu texts, The Upanishads, which French writer Anquetil du Perron had translated from the Persian translation of Prince Dara Shikoh entitled Sirre-Akbar ("The Great Secret"). He was so impressed by their philosophy that he called them "the production of the highest human wisdom", and believed they contained superhuman concepts. The Upanishads was a great source of inspiration to Schopenhauer. Writing about them, he said:
It is the most satisfying and elevating reading (with the exception of the original text) which is possible in the world; it has been the solace of my life and will be the solace of my death.
It is well known that the book Oupnekhat (Upanishad) always lay open on his table, and he invariably studied it before sleeping at night. He called the opening up of Sanskrit literature "the greatest gift of our century" and predicted that the philosophy and knowledge of the Upanishads would become the cherished faith of the West.
Schopenhauer was first introduced to the 1802 Latin Upanishad translation through Friedrich Majer. They met during the winter of 1813–1814 in Weimar at the home of Schopenhauer's mother according to the biographer Safranski. Majer was a follower of Herder, and an early Indologist. Schopenhauer did not begin a serious study of the Indic texts, however, until the summer of 1814. Sansfranski maintains that between 1815 and 1817, Schopenhauer had another important cross-pollination with Indian thought in Dresden. This was through his neighbor of two years, Karl Christian Friedrich Krause. Krause was then a minor and rather unorthodox philosopher who attempted to mix his own ideas with that of ancient Indian wisdom. Krause had also mastered Sanskrit, unlike Schopenhauer, and the two developed a professional relationship. It was from Krause that Schopenhauer learned meditation and received the closest thing to expert advice concerning Indian thought.
Schopenhauer noted a correspondence between his doctrines and the Four Noble Truths of Buddhism. Similarities centered on the principles that life involves suffering, that suffering is caused by desire (taṇhā), and that the extinction of desire leads to liberation. Thus three of the four "truths of the Buddha" correspond to Schopenhauer's doctrine of the will. In Buddhism, however, while greed and lust are always unskillful, desire is ethically variable – it can be skillful, unskillful, or neutral.
For Schopenhauer, Will had ontological primacy over the intellect; in other words, desire is understood to be prior to thought. Schopenhauer felt this was similar to notions of puruṣārtha or goals of life in Vedānta Hinduism.
In Schopenhauer's philosophy, denial of the will is attained by either:
However, Buddhist nirvāṇa is not equivalent to the condition that Schopenhauer described as denial of the will. Nirvāṇa is not the extinguishing of the person as some Western scholars have thought, but only the "extinguishing" (the literal meaning of nirvana) of the flames of greed, hatred, and delusion that assail a person's character. Occult historian Joscelyn Godwin (born 1945) stated, "It was Buddhism that inspired the philosophy of Arthur Schopenhauer, and, through him, attracted Richard Wagner." This Orientalism reflected the struggle of the German Romantics, in the words of Leon Poliakov, to "free themselves from Judeo-Christian fetters". In contradistinction to Godwin's claim that Buddhism inspired Schopenhauer, the philosopher himself made the following statement in his discussion of religions:
If I wished to take the results of my philosophy as the standard of truth, I should have to concede to Buddhism pre-eminence over the others. In any case, it must be a pleasure to me to see my doctrine in such close agreement with a religion that the majority of men on earth hold as their own, for this numbers far more followers than any other. And this agreement must be yet the more pleasing to me, inasmuch as in my philosophizing I have certainly not been under its influence [emphasis added]. For up till 1818, when my work appeared, there was to be found in Europe only a very few accounts of Buddhism.
Buddhist philosopher Nishitani Keiji, however, sought to distance Buddhism from Schopenhauer. While Schopenhauer's philosophy may sound rather mystical in such a summary, his methodology was resolutely empirical, rather than speculative or transcendental:
Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.
This actual world of what is knowable, in which we are and which is in us, remains both the material and the limit of our consideration.
The argument that Buddhism affected Schopenhauer's philosophy more than any other Dharmic faith loses more credence when viewed in light of the fact that Schopenhauer did not begin a serious study of Buddhism until after the publication of The World as Will and Representation in 1818. Scholars have started to revise earlier views about Schopenhauer's discovery of Buddhism. Proof of early interest and influence, however, appears in Schopenhauer's 1815/16 notes (transcribed and translated by Urs App) about Buddhism. They are included in a recent case study that traces Schopenhauer's interest in Buddhism and documents its influence. Other scholarly work questions how similar Schopenhauer's philosophy actually is to Buddhism.
Schopenhauer had a wide range of interests, from science and opera to occultism and literature.
In his student years Schopenhauer went more often to lectures in the sciences than philosophy. He kept a strong interest as his personal library contained near to 200 books of scientific literature at his death, and his works refer to scientific titles not found in the library.:170
Many evenings were spent in the theatre, opera and ballet; the operas of Mozart, Rossini and Bellini were especially esteemed. Schopenhauer considered music to be the highest art and played the flute during his whole life.:30
As polyglot, the philosopher knew German, Italian, Spanish, French, English, Latin and ancient Greek, Schopenhauer was an avid reader of poetry and literature. He particularly revered Goethe, Petrarch, Calderón and Shakespeare.
If Goethe had not been sent into the world simultaneously with Kant in order to counterbalance him, so to speak, in the spirit of the age, the latter would have been haunted like a nightmare many an aspiring mind and would have oppressed it with great affliction. But now the two have an infinitely wholesome effect from opposite directions and will probably raise the German spirit to a height surpassing even that of antiquity.:240
If the reader has also received the benefit of the Vedas, the access to which by means of the Upanishads is in my eyes the greatest privilege which this still young century (1818) may claim before all previous centuries, if then the reader, I say, has received his initiation in primeval Indian wisdom, and received it with an open heart, he will be prepared in the very best way for hearing what I have to tell him. It will not sound to him strange, as to many others, much less disagreeable; for I might, if it did not sound conceited, contend that every one of the detached statements which constitute the Upanishads, may be deduced as a necessary result from the fundamental thoughts which I have to enunciate, though those deductions themselves are by no means to be found there.
Schopenhauer saw Bruno and Spinoza as unique philosophers who were not bound to their age or nation. "Both were fulfilled by the thought, that as manifold the appearances of the world may be, it is still one being, that appears in all of them. ... Consequently, there is no place for God as creator of the world in their philosophy, but God is the world itself."
Schopenhauer expressed his regret that Spinoza stuck for the presentation of his philosophy with the concepts of scholasticism and Cartesian philosophy, and tried to use geometrical proofs that do not hold because of the vagueness and wideness of the definitions. It is the common preference of philosophers of abstraction over perception. Bruno on the other hand, who knew much about nature and ancient literature, presents his ideas with Italian vividness, and is amongst philosophers the only one who comes near Plato's poetic and dramatic power of exposition.
Schopenhauer noted that their philosophies do not provide any ethics, and it is therefore very remarkable that Spinoza called his main work Ethics. In fact, it could be considered to be complete from the standpoint of life-affirmation, if one completely ignores morality and self-denial. It is yet even more remarkable that Schopenhauer mentions Spinoza as an example of the denial of the will, if one uses the French biography by Jean Maximilien Lucas as the key to de Intellectus Emendatione.
Schopenhauer accepted Kant's double-aspect of the universe—the phenomenal (world of experience) and the noumenal (the true world, independent of experience). Some commentators suggest that Schopenhauer claimed that the noumenon, or thing-in-itself, was the basis for Schopenhauer's concept of the will. Other commentators suggest that Schopenhauer considered will to be only a subset of the "thing-in-itself" class, namely that which we can most directly experience.
Schopenhauer's identification of the Kantian noumenon (i.e., the actually existing entity) with what he termed "will" deserves some explanation. The noumenon was what Kant called the Ding an sich (the Thing in Itself), the reality that is the foundation of our sensory and mental representations of an external world. In Kantian terms, those sensory and mental representations are mere phenomena. Schopenhauer departed from Kant in his description of the relationship between the phenomenon and the noumenon. According to Kant, things-in-themselves ground the phenomenal representations in our minds; Schopenhauer, on the other hand, believed that phenomena and noumena are two different sides of the same coin. Noumena do not cause phenomena, but rather phenomena are simply the way by which our minds perceive the noumena, according to the principle of sufficient reason. This is explained more fully in Schopenhauer's doctoral thesis, On the Fourfold Root of the Principle of Sufficient Reason (1813).
Schopenhauer's second major departure from Kant's epistemology concerns the body. Kant's philosophy was formulated as a response to the radical philosophical skepticism of David Hume, who claimed that causality could not be observed empirically. Schopenhauer begins by arguing that Kant's demarcation between external objects, knowable only as phenomena, and the Thing in Itself of noumenon, contains a significant omission. There is, in fact, one physical object we know more intimately than we know any object of sense perception: our own body.
We know our human bodies have boundaries and occupy space, the same way other objects known only through our named senses do. Though we seldom think of our body as a physical object, we know even before reflection that it shares some of an object's properties. We understand that a watermelon cannot successfully occupy the same space as an oncoming truck; we know that if we tried to repeat the experiment with our own body, we would obtain similar results—we know this even if we do not understand the physics involved.
We know that our consciousness inhabits a physical body, similar to other physical objects only known as phenomena. Yet our consciousness is not commensurate with our body. Most of us possess the power of voluntary motion. We usually are not aware of the breathing of our lungs or the beating of our heart unless somehow our attention is called to them. Our ability to control either is limited. Our kidneys command our attention on their schedule rather than one we choose. Few of us have any idea what our liver is doing right now, though this organ is as needful as lungs, heart, or kidneys. The conscious mind is the servant, not the master, of these and other organs. These organs have an agenda the conscious mind did not choose, and over which it has limited power.
When Schopenhauer identifies the noumenon with the desires, needs, and impulses in us that we name "will", what he is saying is that we participate in the reality of an otherwise unachievable world outside the mind through will. We cannot prove that our mental picture of an outside world corresponds with a reality by reasoning; through will, we know—without thinking—that the world can stimulate us. We suffer fear, or desire: these states arise involuntarily; they arise prior to reflection; they arise even when the conscious mind would prefer to hold them at bay. The rational mind is, for Schopenhauer, a leaf borne along in a stream of pre-reflective and largely unconscious emotion. That stream is will, and through will, if not through logic, we can participate in the underlying reality beyond mere phenomena. It is for this reason that Schopenhauer identifies the noumenon with what we call our will.
In his criticism of Kant, Schopenhauer claimed that sensation and understanding are separate and distinct abilities. Yet, for Kant, an object is known through each of them. Kant wrote: "[T]here are two stems of human knowledge ... namely, sensibility and understanding, objects being given by the former [sensibility] and thought by the latter [understanding]." Schopenhauer disagreed. He asserted that mere sense impressions, not objects, are given by sensibility. According to Schopenhauer, objects are intuitively perceived by understanding and are discursively thought by reason (Kant had claimed that (1) "the understanding" thinks of objects through concepts and that (2) "reason" seeks the unconditioned or ultimate answer to "why?"). Schopenhauer said that Kant's mistake regarding perception resulted in all of the obscurity and difficult confusion that is exhibited in the Transcendental Analytic section of his critique.
Kant used the word [Idea] wrongly as well as illegitimately, although Plato had already taken possession of it, and used it most appropriately.
Instead Schopenhauer relied upon the Neoplatonist interpretation of the biographer Diogenes Laërtius from Lives and Opinions of Eminent Philosophers. In reference to Plato's Ideas, Schopenhauer quotes Laërtius verbatim in an explanatory footnote.
Diogenes Laërtius (III, 12) Plato ideas in natura velut exemplaria dixit subsistere; cetera his esse similia, ad istarum similitudinem consistencia. (Plato teaches that the Ideas exist in nature, so to speak, as patterns or prototypes, and that the remainder of things only resemble them, and exist as their copies.)
The leading figures of post-Kantian philosophy, Fichte, Schelling and Hegel, were not respected by Schopenhauer. He argued that they were no philosophers at all, who merely sought to impress the public.
All this explains the painful impression with which we are seized when, after studying genuine thinkers, we come to the writings of Fichte and Schelling, or even to the presumptuously scribbled nonsense of Hegel, produced as it was with a boundless, though justified, confidence in German stupidity. With those genuine thinkers one always found an honest investigation of truth and just as honest an attempt to communicate their ideas to others. Therefore whoever reads Kant, Locke, Hume, Malebranche, Spinoza, and Descartes feels elevated and agreeably impressed. This is produced through communion with a noble mind which has and awakens ideas and which thinks and sets one thinking. The reverse of all this takes place when we read the above-mentioned three German sophists. An unbiased reader, opening one of their books and then asking himself whether this is the tone of a thinker wanting to instruct or that of a charlatan wanting to impress, cannot be five minutes in any doubt; here everything breathes so much of dishonesty.— Appendix to "Sketch of a History of the Doctrine of the Ideal and the Real"
Schelling was deemed to be the most talented of the three, and Schopenhauer wrote that he would recommend his "elucidatory paraphrase of the highly important doctrine of Kant" concerning the intelligible character, if he had been honest enough to admit he was showing off with the thoughts of Kant, instead of hiding this relation in a cunning manner.
Schopenhauer's favourite subject of attacks was Hegel, whom he considered to be unworthy even of Fichte and Schelling. Whereas Fichte was merely a windbag, Hegel was a "stupid and clumsy charlatan". Karl Popper agreed with this distinction.
Schopenhauer had a large posthumous impact and remained the most influential German philosopher until the first World War. His philosophy was a starting point for a new generation of philosophers, which consisted of Julius Bahnsen, Paul Deussen, Lazar Hellenbach, Von Hartmann, Ernst Lindner, Mainländer, Nietzsche, Olga Plümacher and Agnes Talbert. His legacy shaped the intellectual debate, and forced movements that were utterly opposed to him, neo-Kantianism and positivism, to address issues they would otherwise have completely ignored, and in doing so he changed them markedly. The French writer Maupassant commented that "to-day even those who execrate him seem to carry in their own souls particles of his thought." Other philosophers of the 19th century who cited his influence include Hans Vaihinger, Volkelt, Solovyov and Weininger.
Schopenhauer was well read amongst physicists, most notably Einstein, Schrödinger, Wolfgang Pauli, and Majorana. Einstein described Schopenhauer's thoughts to be a "continual consolation" and called him a genius. In his Berlin study three figures hung on the wall: Faraday, Maxwell, Schopenhauer.:87 Konrad Wachsmann recalled: "He often sat with one of the well-worn Schopenhauer volumes, and as he sat there, he seemed so pleased, as if he were engaged with a serene and cheerful work.":92
When Erwin Schrödinger discovered Schopenhauer ("the greatest savant of the West") he considered switching his study of physics to philosophy. He maintained the idealistic and monistic worldview during the rest of his life.:132
But most of all Schopenhauer is famous for his influence on artists. Richard Wagner, writing in his autobiography, remembered his first impression that Schopenhauer left on him (when he read World as Will and Representation):
Schopenhauer's book was never completely out of my mind, and by the following summer I had studied it from cover to cover four times. It had a radical influence on my whole life.
Wagner also commented on that "serious mood, which was trying to find ecstatic expression" created by Schopenhauer inspired the conception of Tristan und Isolde. The admiration was not mutual, and Schopenhauer proclaimed: "I remain faithful to Rossini and Mozart!" Nevertheless, Wagner remained an adherent of Schopenhauer for the rest of his life. See also Influence of Schopenhauer on Tristan und Isolde.
Under the influence of Schopenhauer Leo Tolstoy became convinced that the truth of all religions lies in self-renunciation. When he read his philosophy he exclaimed "at present I am convinced that Schopenhauer is the greatest genius among men. ... It is the whole world in an incomparably beautiful and clear reflection." He said that what he has written in War and Peace is also said by Schopenhauer in The World as Will and Representation.
Jorge Luis Borges remarked that the reason he had never attempted to write a systematic account of his world view, despite his penchant for philosophy and metaphysics in particular, was because Schopenhauer had already written it for him.
Friedrich Nietzsche owed the awakening of his philosophical interest to reading The World as Will and Representation and admitted that he was one of the few philosophers that he respected, dedicating to him his essay Schopenhauer als Erzieher one of his Untimely Meditations.
As a teenager, Ludwig Wittgenstein adopted Schopenhauer's epistemological idealism. However, after his study of the philosophy of mathematics, he rejected epistemological idealism for Gottlob Frege's conceptual realism. In later years, Wittgenstein was highly dismissive of Schopenhauer, describing him as an ultimately shallow thinker: "Schopenhauer has quite a crude mind ... where real depth starts, his comes to an end." His friend Bertrand Russell had a low opinion on the philosopher, and attacked him in his famous History of Western Philosophy for hypocritically praising asceticism yet not acting upon it.
On the opposite isle of Russell on the foundations of mathematics, the Dutch mathematician L. E. J. Brouwer, incorporated the ideas of Kant and Schopenhauer in intuitionism, where mathematics is considered to be a purely mental activity, instead of an analytic activity wherein objective properties of reality are revealed. Brouwer was also influenced by Schopenhauer's metaphysics, and wrote an essay on mysticism.
For the philosopher, these accounts of the lives of holy, self-denying men, badly as they are generally written, and mixed as they are with super stition and nonsense, are, because of the significance of the material, immeasurably more instructive and impor tant than even Plutarch and Livy. ... But the spirit of this development of Christianity is certainly nowhere so fully and powerfully expressed as in the writings of the German mystics, in the works of Meister Eckhard, and in that justly famous book Die Deutsche Theologie.
From Schopenhauer he had learned to regard the independence of spatially separated systems as, virtually, a necessary a priori assumption ... Einstein regarded his separation principle, descended from Schopenhauer's principium individuationis, as virtually an axiom for any future fundamental physics. ... Schopenhauer stressed the essential structuring role of space and time in individuating physical systems and their evolving states. This view implies that difference of location suffices to make two systems different in the sense that each has its own real physical state, independent of the state of the other. For Schopenhauer, the mutual independence of spatially separated systems was a necessary a priori truth.
Kraus himself was no philosopher, even less a scientist. If Kraus's views have a philosophical ancestry, this comes most assuredly from Schopenhauer; for alone among the great philosophers, Schopenhauer was a kindred spirit, a man of philosophical profundity, with a strange talent for polemic and aphorism, a literary as weIl as philosophical genius. Schopenhauer, indeed, was the only philosopher who at all appealed to Kraus.
His interest in philosophy, which had always been great, increased and prompted him to reflect deeply on the works of various philosophers, in particular Schopenhauer.
…but there has been none who tried with so great a show of learning to demonstrate that the pessimistic outlook is justified, that life itself is really bad. It is to this end that Schopenhauer’s metaphysic of will and idea exists.
A more accurate statement might be that for a German – rather than a French or British writer of that time – Schopenhauer was an honest and open atheist.
For Kant, the mathematical sublime, as seen for example in the starry heavens, suggests to imagination the infinite, which in turn leads by subtle turns of contemplation to the concept of God. Schopenhauer's atheism will have none of this, and he rightly observes that despite adopting Kant's distinction between the dynamical and mathematical sublime, his theory of the sublime, making reference to the struggles and sufferings of struggles and sufferings of Will, is unlike Kant's.
Although Schopenhauer was an atheist, he realized that his philosophy of denial had been part of several great religions; for example, Christianity, Hinduism, and Buddhism.
He had also rehearsed for the first time his physiological arguments for the intellectual nature of intuition [Anschauung, objective perception] in his On Vision and Colours, and he had discussed how his philosophy was corroborated by the sciences in On Will in Nature. ... Like the German Idealists, Schopenhauer is convinced that Kant’s great unknown, the thing in itself, is the weak point of the critical philosophy.
With the proof of the thing in itself it has happened to Kant precisely as with that of the a priori nature of the law of causality. Both doctrines are true, but their proof is false. They thus belong to the class of true conclusions from false premises.
But the whole teaching of Kant contains really nothing more about this than the oft-repeated meaningless expression: 'The empirical element in perception is given from without.' ... always through the same meaningless metaphorical expression: 'The empirical perception is given us.'
For sensation is and remains a process within the organism and is limited, as such, to the region within the skin; it cannot therefore contain any thing which lies beyond that region, or, in other words, anything that is outside us. ... It is only when the Understanding begins to apply its sole form, the causal law, that a powerful transformation takes place, by which subjective sensation becomes objective perception.
The contrary doctrine that the law of causality results from experience, which was the scepticism of Hume, is first refuted by this. For the independence of the knowledge of causality of all experience,—that is, its a priori character—can only be deduced from the dependence of all experience upon it; and this deduction can only be accomplished by proving, in the manner here indicated, and explained in the passages referred to above, that the knowledge of causality is included in perception in general, to which all experience belongs, and therefore in respect of experience is completely a priori, does not presuppose it, but is presupposed by it as a condition.
Es kann daher eine vollkommen wahre Philosophie geben, die ganz von der Verneinung des Lebens abstrahirt, diese ganz ignorirt.
We might to a certain extent regard the well-known French biography of Spinoza as a case in point, if we used as a key to it that noble introduction to his very insufficient essay, "De Emendatione Intellects", a passage which I can also recommend as the most effectual means I know of stilling the storm of the passions.
Arthur Schopenhauer was the most famous and influential philosopher in Germany from 1860 until the First World War. ... Schopenhauer had a profound influence on two intellectual movements of the late 19th century that were utterly opposed to him: neo-Kantianism and positivism. He forced these movements to address issues they would otherwise have completely ignored, and in doing so he changed them markedly. ... Schopenhauer set the agenda for his age.
Pauli greatly admired Schopenhauer. ... Pauli wrote sympathetically about extrasensory perception, noting approvingly that "even such a thoroughly critical philosopher as Schopenhauer not only regarded parapsychological effects going far beyond what is secured by scientific evidence as possible, but even considered them as a support for his philosophy".
A thinker of whom it is well known that Santayana had an early, deep admiration, namely, Schopenhauer.
