Transvaluation of values
Friedrich Wilhelm Nietzsche (// or //; German: [ˈfʁiːdʁɪç ˈvɪlhɛlm ˈniːt͡sʃə]; 15 October 1844 – 25 August 1900) was a German philosopher, poet, composer, cultural critic, and classical philologist. He wrote critical texts on religion, morality, contemporary culture, philosophy, and science, displaying a fondness for metaphor, irony, and aphorism.
Nietzsche's key ideas include the "death of God," the Übermensch, the eternal recurrence, the Apollonian and Dionysian dichotomy, perspectivism, and the will to power. Central to his philosophy is the idea of "life-affirmation", which involves questioning of all doctrines that drain life's expansive energies, however socially prevalent those views might be. His influence remains substantial within philosophy, notably in existentialism, post-modernism, and post-structuralism, as well as outside it. His radical questioning of the value and objectivity of truth has been the focus of extensive commentary, especially in the continental tradition.
Nietzsche began his career as a classical philologist before turning to philosophy. In 1869, at the age of twenty-four he was appointed to the Chair of Classical Philology at the University of Basel (the youngest individual to have held this position), but resigned in the summer of 1879 due to health problems that plagued him most of his life. In 1889, at the age of forty-four, he suffered a collapse and a complete loss of his mental faculties. The breakdown had been ascribed to atypical general paresis attributed to tertiary syphilis, but this diagnosis has since come into question. He lived his remaining years in the care of his mother until her death in 1897, then under the care of his sister until his death in 1900.
His sister Elisabeth Förster-Nietzsche acted as curator and editor of Nietzsche's manuscripts during his illness. She was married to a prominent German nationalist and antisemite, Bernhard Förster, and she reworked some of Nietzsche's unpublished writings to fit her husband's ideology, often in ways contrary to Nietzsche's opinions, which were strongly and explicitly opposed to antisemitism and nationalism (see Nietzsche's criticism of anti-Semitism and nationalism). Through Förster-Nietzsche's editions, Nietzsche's name became associated with German militarism and Nazism, although some twentieth century scholars counteract the abuse of Nietzsche's philosophy by this ideology.
Youth (1844–1869) 
Born on October 15, 1844, Nietzsche grew up in the small town of Röcken, near Leipzig, in the Prussian Province of Saxony. He was named after King Frederick William IV of Prussia, who turned forty-nine on the day of Nietzsche's birth (Nietzsche later dropped his given middle name, "Wilhelm"). Nietzsche's parents, Carl Ludwig Nietzsche (1813–49), a Lutheran pastor and former teacher, and Franziska Oehler (1826–97), married in 1843, the year before their son's birth, and had two other children: a daughter, Elisabeth Förster-Nietzsche, born in 1846, and a second son, Ludwig Joseph, born in 1848. Nietzsche's father died from a brain ailment in 1849; Ludwig Joseph died the next year, at age two. The family then moved to Naumburg, where they lived with Nietzsche's maternal grandmother and his father's two unmarried sisters. After the death of Nietzsche's grandmother in 1856, the family moved into their own house, now a museum and Nietzsche study center.
Nietzsche attended a boys' school and then, later, a private school, where he became friends with Gustav Krug, Rudolf Wagner and Wilhelm Pinder, all of whom came from highly respected families.
In 1854, he began to attend Domgymnasium in Naumburg, but since he showed particular talents in music and language, the internationally recognized Schulpforta admitted him as a pupil, and there he continued his studies from 1858 to 1864. Here he became friends with Paul Deussen and Carl von Gersdorff. He also found time to work on poems and musical compositions. At Schulpforta, Nietzsche received an important grounding in languages - Greek, Latin, Hebrew, French - so as to be able to read primary sources of the classical tradition, and experienced for the first time being away from his family life in a small-town conservative environment. His end-of-semester exams in March 1864 showed a 1 in Religion and German, a 2a in Greek and Latin, 2b in French, History and Physics, and a "lackluster" 3 in Hebrew and Mathematics.
While at Pforta, Nietzsche had a penchant for pursuing subjects that were considered unfit. He became acquainted with the work of the then almost unknown poet Friedrich Hölderlin, calling him "my favorite poet" and composing an essay in which he said that the mad poet raised consciousness to "the most sublime ideality." The teacher who corrected the essay gave it a good mark but commented that Nietzsche should concern himself in the future with healthier, more lucid and more German writers. Additionally, he became acquainted with Ernst Ortlepp, an eccentric, blasphemous and often drunk poet who was found dead in a ditch weeks after meeting the young Nietzsche, but who may have introduced Nietzsche to the music and writing of Richard Wagner. Perhaps under Ortlepp's influence, he and a student named Richter returned to school drunk and encountered a teacher, resulting in Nietzsche's demotion from first in his class and the end of his status as a prefect.
After graduation in 1864 Nietzsche commenced studies in theology and classical philology at the University of Bonn. For a short time he and Deussen became members of the Burschenschaft Frankonia. After one semester (and to the anger of his mother) he stopped his theological studies and lost his faith. In 1865, at the age of 20, Nietzsche wrote to his sister, Elisabeth Nietzsche, who was deeply religious, a letter regarding his loss of faith. This letter ended with a following sentence:
"Hence the ways of men part: if you wish to strive for peace of soul and pleasure, then believe; if you wish to be a devotee of truth, then inquire..."
Nietzsche's disbelief may have happened in part of his reading of David Strauss's book Life of Jesus, which had a profound effect on the young Nietzsche, though in an essay entitled Fate and History written in 1862, Nietzsche had already argued that historical research had discredited the central teachings of Christianity. Nietzsche then concentrated on studying philology under Professor Friedrich Wilhelm Ritschl, whom he followed to the University of Leipzig the next year. There he became close friends with fellow student Erwin Rohde. Nietzsche's first philological publications appeared soon thereafter.
In 1865 Nietzsche thoroughly studied the works of Arthur Schopenhauer. He owed the awakening of his philosophical interest to reading Schopenhauer's Die Welt als Wille und Vorstellung (The World as Will and Representation) and later admitted that Schopenhauer was one of the few thinkers whom he respected, dedicating to him his essay Schopenhauer als Erzieher (Schopenhauer as Educator), one of his Untimely Meditations.
In 1866 he read Friedrich Albert Lange's History of Materialism. Lange's descriptions of Kant's anti-materialistic philosophy, the rise of European Materialism, Europe's increased concern with science, Charles Darwin's theory, and general rebellion against tradition and authority intrigued Nietzsche greatly. This cultural environment encouraged him to expand his horizons beyond philology and continue his study of philosophy.
In 1867 Nietzsche signed up for one year of voluntary service with the Prussian artillery division in Naumburg. He was regarded as one of the finest riders among his fellow recruits, and his officers predicted that he would soon reach the rank of captain. However, in March 1868, while jumping into the saddle of his horse, Nietzsche struck his chest against the pommel and tore two muscles in his left side, leaving him exhausted and unable to walk for months. Consequently Nietzsche turned his attention to his studies again, completing them and meeting with Richard Wagner for the first time later that year.
Professor at Basel (1869–1879) 
In part because of Ritschl's support, Nietzsche received a remarkable offer to become professor of classical philology at the University of Basel in Switzerland. He was only 24 years old and had neither completed his doctorate nor received his teaching certificate. Despite the fact that the offer came at a time when he was considering giving up philology for science, he accepted. To this day, Nietzsche is still among the youngest of the tenured Classics professors on record. Before moving to Basel, Nietzsche renounced his Prussian citizenship: for the rest of his life he remained officially stateless.
Nevertheless, Nietzsche served in the Prussian forces during the Franco-Prussian War of 1870 to 1871 as a medical orderly. In his short time in the military he experienced much, and witnessed the traumatic effects of battle. He also contracted diphtheria and dysentery. Walter Kaufmann speculates that he might also have contracted syphilis along with his other infections at this time, and some biographers speculate that syphilis caused his eventual dementia, though there is some disagreement on this matter. On returning to Basel in 1870 Nietzsche observed the establishment of the German Empire and the following era of Otto von Bismarck as an outsider and with a degree of skepticism regarding its genuineness. At the University, he delivered his inaugural lecture, "Homer and Classical Philology." Nietzsche also met Franz Overbeck, a professor of theology, who remained his friend throughout his life. Afrikan Spir, a little-known Russian philosopher and author of Denken und Wirklichkeit (1873), and Nietzsche's colleague the historian Jacob Burckhardt, whose lectures Nietzsche frequently attended, began to exercise significant influence on him during this time.
Nietzsche had already met Richard Wagner in Leipzig in 1868, and (some time later) Wagner's wife Cosima. Nietzsche admired both greatly, and during his time at Basel frequently visited Wagner's house in Tribschen in the Canton of Lucerne. The Wagners brought Nietzsche into their most intimate circle, and enjoyed the attention he gave to the beginning of the Bayreuth Festival Theatre. In 1870 he gave Cosima Wagner the manuscript of 'The Genesis of the Tragic Idea' as a birthday gift. In 1872 Nietzsche published his first book, The Birth of Tragedy. However, his colleagues in the field of classical philology, including Ritschl, expressed little enthusiasm for the work, in which Nietzsche eschewed the classical philologic method in favor of a more speculative approach. In a polemic, Philology of the Future, Ulrich von Wilamowitz-Moellendorff dampened the book's reception and increased its notoriety. In response, Rohde (by now a professor in Kiel) and Wagner came to Nietzsche's defense. Nietzsche remarked freely about the isolation he felt within the philological community and attempted to attain a position in philosophy at Basel, though unsuccessfully.
Between 1873 and 1876, Nietzsche published separately four long essays: David Strauss: the Confessor and the Writer, On the Use and Abuse of History for Life, Schopenhauer as Educator, and Richard Wagner in Bayreuth. These four later appeared in a collected edition under the title Untimely Meditations. The four essays shared the orientation of a cultural critique, challenging the developing German culture along lines suggested by Schopenhauer and Wagner. In 1873, Nietzsche also began to accumulate notes that would be posthumously published as Philosophy in the Tragic Age of the Greeks. During this time, in the circle of the Wagners, Nietzsche met Malwida von Meysenbug and Hans von Bülow, and also began a friendship with Paul Rée, who in 1876 influenced him in dismissing the pessimism in his early writings. However, he was deeply disappointed by the Bayreuth Festival of 1876, where the banality of the shows and the baseness of the public repelled him. He was also alienated by Wagner's championing of 'German culture,' which Nietzsche thought a contradiction in terms, as well as by Wagner's celebration of his fame among the German public. All this contributed to Nietzsche's subsequent decision to distance himself from Wagner.
With the publication in 1878 of Human, All Too Human (a book of aphorisms on subjects ranging from metaphysics to morality and from religion to the sexes), Nietzsche's reaction against the pessimistic philosophy of Wagner and Schopenhauer became evident, as well as the influence of Afrikan Spir's Denken und Wirklichkeit. Nietzsche's friendship with Deussen and Rohde cooled as well. In 1879, after a significant decline in health, Nietzsche had to resign his position at Basel. (Since his childhood, various disruptive illnesses had plagued him, including moments of shortsightedness that left him nearly blind, migraine headaches, and violent indigestion. The 1868 riding accident and diseases in 1870 may have aggravated these persistent conditions, which continued to affect him through his years at Basel, forcing him to take longer and longer holidays until regular work became impractical).
Independent philosopher (1879–1888) 
Because his illness drove him to find climates more conducive to his health, Nietzsche traveled frequently, and lived until 1889 as an independent author in different cities. He spent many summers in Sils Maria, near St. Moritz in Switzerland, and many winters in the Italian cities of Genoa, Rapallo and Turin and in the French city of Nice. In 1881, when France occupied Tunisia, he planned to travel to Tunis to view Europe from the outside, but later abandoned that idea (probably for health reasons). While in Genoa, Nietzsche's failing eyesight prompted him to explore the use of typewriters as a means of continuing to write. He is known to have tried using the Hansen Writing Ball, a contemporary typewriter device.
Nietzsche occasionally returned to Naumburg to visit his family, and, especially during this time, he and his sister had repeated periods of conflict and reconciliation. He lived on his pension from Basel, but also received aid from friends.
A past student of his, Peter Gast (born Heinrich Köselitz), became a sort of private secretary to Nietzsche. In 1876, Koselitz transcribed the crabbed, nearly illegible handwriting of Nietzsche for the first time with Richard Wagner in Bayreuth. He would go on to both transcribe and proofread the galleys for almost all of Nietzsche's work from there on. On at least one occasion, February 23, 1880, the usually broke Koselitz received 200 marks from their mutual friend, Paul Rée. Koselitz was one of the very few friends Nietzsche allowed to criticize him. In responding most enthusiastically to Zarathustra, Koselitz did feel it necessary to point out that what were described as "superfluous" people were in fact quite necessary. He went on to list the number of people Epicurus, for example, had to rely on—even with his simple diet of goat cheese.
To the end of his life, Gast and Overbeck remained consistently faithful friends. Malwida von Meysenbug remained like a motherly patron even outside the Wagner circle. Soon Nietzsche made contact with the music-critic Carl Fuchs. Nietzsche stood at the beginning of his most productive period. Beginning with Human, All Too Human in 1878, Nietzsche would publish one book (or major section of a book) each year until 1888, his last year of writing, during which he completed five.
In 1882 Nietzsche published the first part of The Gay Science. That year he also met Lou Andreas Salomé, through Malwida von Meysenbug and Paul Rée. Nietzsche and Salomé spent the summer together in Tautenburg in Thuringia, often with Nietzsche's sister Elisabeth as a chaperone. Nietzsche, however, regarded Salomé less as an equal partner than as a gifted student. Salomé reports that he asked her to marry him and that she refused, though the reliability of her reports of events has come into question. Nietzsche's relationship with Rée and Salomé broke up in the winter of 1882/1883, partially because of intrigues conducted by Nietzsche's sister Elisabeth. Amidst renewed bouts of illness, living in near isolation after a falling-out with his mother and sister regarding Salomé, Nietzsche fled to Rapallo. Here he wrote the first part of Thus Spoke Zarathustra in only ten days.
By 1882, Nietzsche was taking huge doses of opium, but was still having trouble sleeping. In 1883, while staying in Nice, he was writing out his own prescriptions for the sedative chloral hydrate, signing them 'Dr Nietzsche'.
After severing his philosophical ties with Schopenhauer (who was long dead and never met Nietzsche) and his social ties with Wagner, Nietzsche had few remaining friends. Now, with the new style of Zarathustra, his work became even more alienating and the market received it only to the degree required by politeness. Nietzsche recognized this and maintained his solitude, though he often complained about it. His books remained largely unsold. In 1885 he printed only 40 copies of the fourth part of Zarathustra, and distributed only a fraction of these among close friends, including Helene von Druskowitz.
In 1883 he tried and failed to obtain a lecturing post at the University of Leipzig. It was made clear to him that, in view of the attitude towards Christianity and the concept of God expressed in Zarathustra, he had become in effect unemployable at any German University. The subsequent "feelings of revenge and resentment" embittered him. "And hence my rage since I have grasped in the broadest possible sense what wretched means (the depreciation of my good name, my character and my aims) suffice to take from me the trust of, and therewith the possibility of obtaining, pupils."
In 1886 Nietzsche broke with his publisher, Ernst Schmeitzner, disgusted by his anti-Semitic opinions. Nietzsche saw his own writings as "completely buried and unexhumeable in this anti-Semitic dump" of Schmeitzner — associating the publisher with a movement that should be "utterly rejected with cold contempt by every sensible mind". He then printed Beyond Good and Evil at his own expense, and issued in 1886–1887 second editions of his earlier works (The Birth of Tragedy, Human, All Too Human, Dawn, and The Gay Science), accompanied by new prefaces in which he reconsidered his earlier works. Thereafter, he saw his work as completed for a time and hoped that soon a readership would develop. In fact, interest in Nietzsche's thought did increase at this time, if rather slowly and in a way hardly perceived by him. During these years Nietzsche met Meta von Salis, Carl Spitteler, and also Gottfried Keller. Nietzsche had acquired the publication-rights for his earlier works in 1886 and began a process of editing and re-formulation that placed the body of his work in a more coherent perspective. In the same year, his sister Elisabeth married the anti-Semite Bernhard Förster and traveled to Paraguay to found Nueva Germania, a "Germanic" colony—a plan to which Nietzsche responded with mocking laughter. Through correspondence, Nietzsche's relationship with Elisabeth continued on the path of conflict and reconciliation, but they would meet again only after his collapse. He continued to have frequent and painful attacks of illness, which made prolonged work impossible. In 1887 Nietzsche wrote the polemic On the Genealogy of Morals.
During the same year Nietzsche encountered the work of Fyodor Dostoevsky, with whom he felt an immediate kinship. He also exchanged letters with Hippolyte Taine, and then also with Georg Brandes. Brandes, who had started to teach the philosophy of Søren Kierkegaard in the 1870s, wrote to Nietzsche asking him to read Kierkegaard, to which Nietzsche replied that he would come to Copenhagen and read Kierkegaard with him. However, before fulfilling this undertaking, he slipped too far into sickness. In the beginning of 1888, in Copenhagen, Brandes delivered one of the first lectures on Nietzsche's philosophy.
Although Nietzsche had in 1886 announced (at the end of On The Genealogy of Morality) a new work with the title The Will to Power: Attempt at a Revaluation of All Values, he eventually seems to have abandoned this particular approach and instead used some of the draft passages to compose Twilight of the Idols and The Antichrist (both written in 1888).
His health seemed to improve, and he spent the summer in high spirits. In the fall of 1888 his writings and letters began to reveal a higher estimation of his own status and "fate". He overestimated the increasing response to his writings, especially to the recent polemic, The Case of Wagner. On his 44th birthday, after completing Twilight of the Idols and The Antichrist, he decided to write the autobiography Ecce Homo. In the preface to this work—which suggests Nietzsche was well aware of the interpretive difficulties his work would generate—he declares, "Hear me! For I am such and such a person. Above all, do not mistake me for someone else." In December, Nietzsche began a correspondence with August Strindberg, and thought that, short of an international breakthrough, he would attempt to buy back his older writings from the publisher and have them translated into other European languages. Moreover, he planned the publication of the compilation Nietzsche Contra Wagner and of the poems that composed his collection Dionysian-Dithyrambs.
Mental breakdown and death (1889–1900) 
On January 3, 1889, Nietzsche suffered a mental collapse. Two policemen approached him after he caused a public disturbance in the streets of Turin. What happened remains unknown, but an often-repeated tale from shortly after his death states that Nietzsche witnessed the flogging of a horse at the other end of the Piazza Carlo Alberto, ran to the horse, threw his arms up around its neck to protect it, and then collapsed to the ground.
In the following few days, Nietzsche sent short writings—known as the Wahnbriefe ("Madness Letters")—to a number of friends (including Cosima Wagner and Jacob Burckhardt). To his former colleague Burckhardt, Nietzsche wrote: "I have had Caiaphas put in fetters. Also, last year I was crucified by the German doctors in a very drawn-out manner. Wilhelm, Bismarck, and all anti-Semites abolished."[page needed] Additionally, he commanded the German emperor to go to Rome to be shot, and summoned the European powers to take military action against Germany.
On January 6, 1889, Burckhardt showed the letter he had received from Nietzsche to Overbeck. The following day Overbeck received a similarly revealing letter, and decided that Nietzsche's friends had to bring him back to Basel. Overbeck traveled to Turin and brought Nietzsche to a psychiatric clinic in Basel. By that time Nietzsche appeared fully in the grip of a serious mental illness, and his mother Franziska decided to transfer him to a clinic in Jena under the direction of Otto Binswanger. From November 1889 to February 1890 the art historian Julius Langbehn attempted to cure Nietzsche, claiming that the methods of the medical doctors were ineffective in treating Nietzsche's condition. Langbehn assumed progressively greater control of Nietzsche until his secretiveness discredited him. In March 1890 Franziska removed Nietzsche from the clinic, and in May 1890 brought him to her home in Naumburg. During this process Overbeck and Gast contemplated what to do with Nietzsche's unpublished works. In January 1889 they proceeded with the planned release of Twilight of the Idols, by that time already printed and bound. In February they ordered a fifty copy private edition of Nietzsche contra Wagner, but the publisher C. G. Naumann secretly printed one hundred. Overbeck and Gast decided to withhold publishing The Antichrist and Ecce Homo because of their more radical content. Nietzsche's reception and recognition enjoyed their first surge.
In 1893 Nietzsche's sister Elisabeth returned from Nueva Germania (in Paraguay) following the suicide of her husband. She read and studied Nietzsche's works, and piece by piece took control of them and of their publication. Overbeck eventually suffered dismissal, and Gast finally co-operated. After the death of Franziska in 1897, Nietzsche lived in Weimar, where Elisabeth cared for him and allowed people, including Rudolf Steiner (who in 1895 had written one of the first books praising Nietzsche)[page needed] to visit her uncommunicative brother. Elisabeth at one point went so far as to employ Steiner as a tutor to help her to understand her brother's philosophy. Steiner abandoned the attempt after only a few months, declaring that it was impossible to teach her anything about philosophy.
Nietzsche's mental illness was originally diagnosed as tertiary syphilis, in accordance with a prevailing medical paradigm of the time. Although most commentators regard his breakdown as unrelated to his philosophy, Georges Bataille drops dark hints ("'man incarnate' must also go mad") and René Girard's postmortem psychoanalysis posits a worshipful rivalry with Richard Wagner. The diagnosis of syphilis was challenged, and manic-depressive illness with periodic psychosis, followed by vascular dementia was put forward by Cybulska. prior Schain's. Sax suggested slow growing meningioma as an explanation of Nietzsche’s dementia., while Orth and Trimble postulated frontotemporal dementia,. Other researchers proposed a syndrome called CADASIL.
In 1898 and 1899 Nietzsche suffered at least two strokes, which partially paralysed him and left him unable to speak or walk. After contracting pneumonia in mid-August 1900 he had another stroke during the night of August 24–25, and died about noon on August 25. Elisabeth had him buried beside his father at the church in Röcken bei Lützen. His friend, Gast, gave his funeral oration, proclaiming: "Holy be your name to all future generations!" Nietzsche had written in Ecce Homo (at the time of the funeral still unpublished) of his fear that one day his name would be regarded as "holy".
Elisabeth Förster-Nietzsche compiled The Will to Power from Nietzsche's unpublished notebooks, and published it posthumously. Because his sister arranged the book based on her own conflation of several of Nietzsche's early outlines, and took great liberties with the material, the consensus holds that it does not reflect Nietzsche's intent. Indeed, Mazzino Montinari, the editor of Nietzsche's Nachlass, called it a forgery in The 'Will to Power' Does Not Exist. For example, Elisabeth removed aphorism 35 of The Antichrist, where Nietzsche rewrote a passage of the Bible.
Citizenship, nationality, ethnicity 
General commentators and Nietzsche scholars, whether emphasizing his cultural background or his language, overwhelmingly label Nietzsche as a "German philosopher". Others do not assign him a national category. Germany had not yet been unified into a nation-state but Nietzsche was born a citizen of Prussia, which was then part of the German Confederation. His birthplace, Röcken, is in the modern German state of Saxony-Anhalt. When he accepted his post at Basel, Nietzsche applied for the annulment of his Prussian citizenship. The official response confirming the revocation of his citizenship came in a document dated April 17, 1869, and for the rest of his life he remained officially stateless.
Nietzsche believed that his ancestors were Polish. Nietzsche himself subscribed to this story toward the end of his life. He wrote in 1888, "My ancestors were Polish noblemen (Nietzky); the type seems to have been well preserved despite three generations of German mothers." At one point Nietzsche becomes even more adamant about his Polish identity. "I am a pure-blooded Polish nobleman, without a single drop of bad blood, certainly not German blood." On yet another occasion Nietzsche stated "Germany is a great nation only because its people have so much Polish blood in their veins [...] I am proud of my Polish descent." Nietzsche believed his name might have been Germanized, in one letter claiming, "I was taught to ascribe the origin of my blood and name to Polish noblemen who were called Niëtzky and left their home and nobleness about a hundred years ago, finally yielding to unbearable suppression: they were Protestants."
Most scholars dispute Nietzsche's account of his family's origins. Hans von Müller debunked the genealogy put forward by Nietzsche's sister in favor of a Polish noble heritage. Max Oehler, the curator of the Nietzsche Archive at Weimar, argued that all of Nietzsche's ancestors bore German names, even the wives' families. Oehler claims that Nietzsche came from a long line of German Lutheran clergymen on both sides of his family, and modern scholars regard the claim of Nietzsche's Polish ancestry as a "pure invention". Colli and Montinari, the editors of Nietzsche's assembled letters, gloss Nietzsche's claims as a "mistaken belief" and "without foundation." The name Nietzsche itself is not a Polish name, but an exceptionally common one throughout central Germany, in this and cognate forms (such as Nitsche and Nitzke). The name derives from the forename Nikolaus, abbreviated to Nick; assimilated with the Slavic Nitz, it first became Nitsche and then Nietzsche.
It is not known why Nietzsche wanted to be thought of as Polish nobility. According to biographer R. J. Hollingdale, Nietzsche's propagation of the Polish ancestry myth may have been part of the latter's "campaign against Germany".
Relationships and sexuality 
Despite a proposal to Lou Salomé, Nietzsche never married. The Nietzsche scholar Joachim Köhler has attempted to explain Nietzsche's life history and philosophy by claiming that Nietzsche was a homosexual. Köhler argues that Nietzsche's syphilis, which is "usually considered to be the product of his encounter with a prostitute in a brothel in Cologne or Leipzig, is equally likely, it is now held, to have been contracted in a male brothel in Genoa". Köhler also suggests Nietzsche may have had a romantic relationship as well as a friendship with Paul Rée. Köhler's views have not found wide acceptance among Nietzsche scholars and commentators: in The Journal of Modern History, Allan Megill argues that "Köhler does establish that the claim that Nietzsche was a man in confrontation with homosexual desire cannot simply be dismissed" but notes that "the evidence is very weak" and argues that Köhler may be projecting twentieth-century understandings of sexuality on nineteenth-century notions of friendship. Other scholars have argued that Köhler's sexuality-based interpretation is not fruitful in understanding Nietzsche's philosophy.
Nietzsche is known for his use of poetry and prose (sometimes together in poetic prose style) in his writings. An excellent example is his iconic phrase "God is dead", in German: Gott ist tot. This, combined with the fact that he disdained any kind of system, has made several aspects of his philosophy seemingly lacking coherent meaning or being paradoxical. Because of Nietzsche's evocative style and his often outrageous claims, his philosophy generates passionate reactions running from love to disgust, and it has drawn amateurs of all kinds to be heavily involved in the project of interpretation as well. His works remain controversial, due to interpretations and misinterpretations of his work. In Western philosophy tradition, Nietzsche's writings are the unique case of free revolutionary thought that is revolutionary in its structure and problems but isn't tied to any revolutionary project at all.
In The Dawn Nietzsche begins his "Campaign against Morality". He calls himself an "immoralist" and harshly criticizes the prominent moral philosophies of his day: Christianity, Kantianism, and utilitarianism. Nietzsche is also known for being very critical of the Western belief in egalitarianism and rationality. Nietzsche's concept "God is dead" applies to the doctrines of Christendom, though not to all other faiths: he claimed that Buddhism is a successful religion that he compliments for fostering critical thought. Still, Nietzsche saw his philosophy as a counter-movement to nihilism through appreciation of art:
Art as the single superior counterforce against all will to negation of life, art as the anti-Christian, anti-Buddhist, anti-Nihilist par excellence."
Nietzsche claimed that the Christian faith as practiced was not a proper representation of Jesus' teachings, as it forced people merely to believe in the way of Jesus but not to act as Jesus did, in particular his example of refusing to judge people, something that Christians had constantly done the opposite of. He condemned institutionalized Christianity for emphasizing a morality of pity (Mitleid), which assumes an inherent illness in society:
Christianity is called the religion of pity. Pity stands opposed to the tonic emotions which heighten our vitality: it has a depressing effect. We are deprived of strength when we feel pity. That loss of strength which suffering as such inflicts on life is still further increased and multiplied by pity. Pity makes suffering contagious.
In Ecce Homo Nietzsche called the establishment of moral systems based on a dichotomy of good and evil a "calamitous error", and wished to initiate a re-evaluation of the values of the Judeo-Christian world. He indicates his desire to bring about a new, more naturalistic source of value in the vital impulses of life itself. While Nietzsche attacked the principles of Judaism, he was not anti-Semitic: in his work On the Genealogy of Morality, he explicitly condemns anti-Semitism, and pointed out that his attack on Judaism was not an attack on Jews as a people but specifically an attack upon the ancient Jewish priesthood whom he claims anti-Semitic Christians paradoxically based their views upon.
The "slave revolt" in morals 
In Beyond Good And Evil and On the Genealogy of Morality, Nietzsche's genealogical account of the development of modern moral systems occupies central place. For Nietzsche, a fundamental shift took place from thinking in terms of "good" and "bad" toward "good" and "evil."
The initial form of morality was set by a warrior aristocracy and other ruling castes of ancient civilizations. Aristocratic values of "good" and "bad" coincided with and reflected their relationship to lower castes such as slaves. Nietzsche presents this "master morality" as the original system of morality—perhaps best associated with Homeric Greece. To be "good" was to be happy and to have the things related to happiness: wealth, strength, health, power, etc. To be "bad" was to be like the slaves over which the aristocracy ruled, poor, weak, sick, pathetic—an object of pity or disgust rather than hatred.
"Slave morality" comes about as a reaction to master-morality. Here, value emerges from the contrast between good and evil: good being associated with other-worldliness, charity, piety, restraint, meekness, and submission; and evil seen as worldly, cruel, selfish, wealthy, and aggressive. Nietzsche sees slave morality as pessimistic and fearful, values for them serving only to ease the existence for those who suffer from the very same thing. He associates slave-morality with the Jewish and Christian traditions, in a way that slave-morality is born out of the ressentiment of slaves. Nietzsche argued that the idea of equality allowed slaves to overcome their own condition without hating themselves. And by denying the inherent inequality of people (such as success, strength, beauty or intelligence), slaves acquired a method of escape, namely by generating new values on the basis of rejecting something that was seen as a perceived source of frustration. It was used to overcome the slave's own sense of inferiority before the (better-off) masters. It does so by making out slave weakness to be a matter of choice, by, e.g., relabeling it as "meekness." The "good man" of master morality is precisely the "evil man" of slave morality, while the "bad man" is recast as the "good man."
Nietzsche sees the slave-morality as a source of the nihilism that has overtaken Europe. Modern Europe and Christianity exist in a hypocritical state due to a tension between master and slave morality, both values contradictorily determining, to varying degrees, the values of most Europeans (who are motley). Nietzsche calls for exceptional people to no longer be ashamed of their uniqueness in the face of a supposed morality-for-all, which he deems to be harmful to the flourishing of exceptional people. He cautions, however, that morality, per se, is not bad; it is good for the masses, and should be left to them. Exceptional people, on the other hand, should follow their own "inner law." A favorite motto of Nietzsche, taken from Pindar, reads: "Become what you are."
A long standing assumption about Nietzsche is that he preferred master over slave morality. However, Nietzsche scholar Walter Kaufmann rejected this interpretation, writing that Nietzsche's analyses of these two types of morality were only used in a descriptive and historic sense, they were not meant for any kind of acceptance or glorifications.
Death of God and nihilism 
The statement God is dead, occurring in several of Nietzsche's works (notably in The Gay Science), has become one of his best-known remarks. On the basis of it, most commentators regard Nietzsche as an atheist; others (such as Kaufmann) suggest that this statement reflects a more subtle understanding of divinity. Recent developments in modern science and the increasing secularization of European society had effectively 'killed' the Abrahamic god, who had served as the basis for meaning and value in the West for more than a thousand years. The death of God may lead beyond bare perspectivism to outright nihilism, the belief that nothing has any inherent importance and that life lacks purpose. Here he states that the Christian moral doctrine provides people with intrinsic value, belief in God (which justifies the evil in the world) and a basis for objective knowledge. In this sense, in constructing a world where objective knowledge is possible, Christianity is an antidote against a primal form of nihilism, against the despair of meaninglessness. As Heidegger put the problem, "If God as the suprasensory ground and goal of all reality is dead, if the suprasensory world of the ideas has suffered the loss of its obligatory and above it its vitalizing and upbuilding power, then nothing more remains to which man can cling and by which he can orient himself."
One such reaction to the loss of meaning is what Nietzsche calls 'passive nihilism', which he recognises in the pessimistic philosophy of Schopenhauer. Schopenhauer's doctrine, which Nietzsche also refers to as Western Buddhism, advocates a separating oneself of will and desires in order to reduce suffering. Nietzsche characterises this ascetic attitude as a "will to nothingness", whereby life turns away from itself, as there is nothing of value to be found in the world. This moving away of all value in the world is characteristic of the nihilist, although in this, the nihilist appears to be inconsistent:
A nihilist is a man who judges of the world as it is that it ought not to be, and of the world as it ought to be that it does not exist. According to this view, our existence (action, suffering, willing, feeling) has no meaning: the pathos of 'in vain' is the nihilists' pathos — at the same time, as pathos, an inconsistency on the part of the nihilists.—Friedrich Nietzsche, KSA 12:9 , taken from The Will to Power, section 585, translated by Walter Kaufmann
Nietzsche approaches the problem of nihilism as a deeply personal one, stating that this problem of the modern world is a problem that has "become conscious" in him. Furthermore, he emphasises both the danger of nihilism and the possibilities it offers, as seen in his statement that "I praise, I do not reproach, [nihilism's] arrival. I believe it is one of the greatest crises, a moment of the deepest self-reflection of humanity. Whether man recovers from it, whether he becomes master of this crisis, is a question of his strength!" According to Nietzsche, it is only when nihilism is overcome that a culture can have a true foundation upon which to thrive. He wished to hasten its coming only so that he could also hasten its ultimate departure. Heidegger interprets the death of God with what he explains as the death of metaphysics. He concludes that metaphysics has reached its potential and that the ultimate fate and downfall of metaphysics was proclaimed with the statement God is dead.
Apollonian and Dionysian 
The Apollonian and Dionysian is a philosophical concept, or dichotomy, based on certain features of ancient Greek mythology, in this case Apollo and Dionysus. While the concept is famously related to The Birth of Tragedy, poet Hölderlin spoke of them before, and Winckelmann talked of Bacchus. One year before the publication of The Birth of Tragedy, Nietzsche wrote a fragment titled On Music and Words. In it he asserted the Schopenhauerian judgment that music is a primary expression of the essence of everything. Secondarily derivative are lyrical poetry and drama, which represent mere phenomenal appearances of objects. In this way, tragedy is born from music.
Nietzsche found in classical Athenian tragedy an art form that transcended the pessimism and nihilism of a fundamentally meaningless world. The Greek spectators, by looking into the abyss of human suffering and affirming it, passionately and joyously affirmed the meaning of their own existence. His major premise in The Birth of Tragedy was that the fusion of Dionysian and Apollonian "Kunsttrieben" ("artistic impulses") forms dramatic arts, or tragedies. He goes on to argue that this fusion has not been achieved since the ancient Greek tragedians. Apollo represents harmony, progress, clarity and logic whereas Dionysus represents disorder, intoxication, emotion and ecstasy. Nietzsche used these two forces because, for him, the world of mind and order on one side, and passion and chaos on other formed principles that were fundamental to the Greek culture. Apollonian side being a dreaming state, full of illusions; and Dionysian being the state of intoxication, representing the liberations of instinct and dissolution of boundaries. In this mold, man appears as the satyr. He is the horror of the annihilation of the principle of individuality and at the same time someone who delights in its destruction. Both of these principles are meant to represent cognitive states that appear through art as the power of nature in man.
The relationship between the Apollonian and Dionysian juxtapositions is apparent, in the interplay of tragedy: the tragic hero of the drama, the main protagonist, struggles to make order (in the Apollonian sense) of his unjust and chaotic (Dionysian) fate, though he dies unfulfilled in the end. Elaborating on the conception of Hamlet as an intellectual who cannot make up his mind, and therefore is a living antithesis to the man of action, Nietzsche argues that a Dionysian figure possesses knowledge to realize that his actions cannot change the eternal balance of things, and it disgusts him enough not to be able to make any act at all. Hamlet falls under this category – he has glimpsed the supernatural reality through the Ghost, he has gained true knowledge and knows that no action of his has the power to change this. For the audience of such drama, this tragedy allows them to sense an underlying essence, what Nietzsche called the Primordial Unity, which revives Dionysian nature. He describes this primordial unity as the increase of strength, experience of fullness and plenitude bestowed by frenzy. Frenzy acts as an intoxication, and is crucial for the physiological condition that enables making of any art. Stimulated by this state, person's artistic will is enhanced:
"In this state one enriches everything out of one's own fullness: whatever one sees, whatever wills is seen swelled, taut, strong, overloaded with strength. A man in this state transforms things until they mirror his power - until they are reflections of his perfection. This having to transform into perfection is - art."
Nietzsche is adamant that the works of Aeschylus and Sophocles represent the apex of artistic creation, the true realization of tragedy; it is with Euripides, he states, that tragedy begins its "Untergang" (literally "going under", meaning decline, deterioration, downfall, death, etc.). Nietzsche objects to Euripides' use of Socratic rationalism and morality in his tragedies, claiming that the infusion of ethics and reason robs tragedy of its foundation, namely the fragile balance of the Dionysian and Apollonian. Socrates emphasized reason to such a degree that he diffused the value of myth and suffering to human knowledge. Plato continued with this path in his dialogues and modern world eventually inherited reason at the expense of artistic impulses that could be found only in the Apollonian and Dionysus dichotomy. This leads to his conclusion that European culture from the time of Socrates had always been only Apollonian and thus decadent and unhealthy. He notes that whenever Apollonian culture dominates, the Dionysian lacks the structure to make a coherent art, and when Dionysian dominates, the Apollonian lacks the necessary passion. Only the beautiful middle; the interplay of these two forces brought together as an art represented real Greek tragedy.
An example of the impact of this idea can be seen in the book Patterns of Culture, where anthropologist Ruth Benedict uses Nietzschean opposites of "Apollonian" and "Dionysian" as the stimulus for her thoughts about Native American cultures. Carl Jung has written extensively on the dichotomy in Psychological Types. Michel Foucault has commented that his book Madness and Civilization should be read "under the sun of the great Nietzschean inquiry". Here Foucault references Nietzsche's description of the birth and death of tragedy and his explanation that the subsequent tragedy of the Western world was the refusal of tragic and, with that, refusal of the sacred. Painter Mark Rothko was influenced by Nietzsche's view of tragedy, which were presented in The Birth of Tragedy.
Nietzsche claimed the death of God would eventually lead to the loss of any universal perspective on things, and along with it any coherent sense of objective truth.[page needed] Nietzsche himself rejected the idea of objective reality arguing that knowledge is contingent and conditional, relative to various fluid perspectives or interests. This leads to constant reassessment of rules (i.e., those of philosophy, the scientific method, etc.) according to the circumstances of individual perspectives. This view has acquired the name perspectivism.
In Thus Spoke Zarathustra, Nietzsche proclaims that a table of values hangs above every great people. He points out that what is common among different peoples is the act of esteeming, of creating values, even if the values are different from one people to the next. Nietzsche asserts that what made people great was not the content of their beliefs, but the act of valuing. Thus the values a community strives to articulate are not as important as the collective will to see those values come to pass. The willing is more essential than the intrinsic worth of the goal itself, according to Nietzsche. "A thousand goals have there been so far," says Zarathustra, "for there are a thousand peoples. Only the yoke for the thousand necks is still lacking: the one goal is lacking. Humanity still has no goal." Hence, the title of the aphorism, "On The Thousand And One Goals". The idea that one value-system is no more worthy than the next, although it may not be directly ascribed to Nietzsche, has become a common premise in modern social science. Max Weber and Martin Heidegger absorbed it and made it their own. It shaped their philosophical and cultural endeavor, as well as their political understanding. Weber for example, relies on Nietzsche's perspectivism by maintaining that objectivity is still possible—but only after a particular perspective, value, or end has been established.
Among his critique of traditional philosophy of Kant, Descartes and Plato in Beyond Good and Evil, Nietzsche attacked thing in itself and cogito ergo sum (I think, therefore I am) as unfalsifiable beliefs based on naive acceptance of previous notions and fallacies. Philosopher Alasdair MacIntyre puts Nietzsche in a high place in the history of philosophy. While criticizing nihilism and Nietzsche together as a sign of general decay, he still commends him for recognizing psychological motives behind Kant and Hume's moral philosophy:
For it was Nietzsche's historic achievement to understand more clearly than any other philosopher...not only that what purported to be appeals of objectivity were in fact expressions of subjective will, but also the nature of the problems that this posed for philosophy.
Will to power 
A basic element in Nietzsche's philosophical outlook is the will to power (der Wille zur Macht), which provides a basis for understanding human behavior — more so than competing explanations, such as the ones based on pressure for adaptation or survival. As such, according to Nietzsche, the drive for conservation appears as the major motivator of human or animal behavior only in exceptions, as the general condition of life is not one of emergency, of 'struggle for existence'. More often than not, self-conservation is but a consequence of a creature's will to exert its strength on the outside world.
In presenting his theory of human behavior, Nietzsche also addressed, and attacked, concepts from philosophies popularly embraced in his days, such as Schopenhauer's notion of an aimless will or that of utilitarianism. Utilitarians claim that what moves people is mainly the desire to be happy, to accumulate pleasure in their lives. But such a conception of happiness Nietzsche rejected as something limited to, and characteristic of, the bourgeois lifestyle of the English society, and instead put forth the idea that happiness is not an aim per se — it is instead a consequence of a successful pursuit of one's aims, of the overcoming of hurdles to one's actions — in other words, of the fulfillment of the will.
Related to his theory of the will to power, is his speculation, which he did not deem final, regarding the reality of the physical world, including inorganic matter — that, like man's affections and impulses, the material world is also set by the dynamics of a form of the will to power. At the core of his theory is a rejection of atomism — the idea that matter is composed of stable, indivisible units (atoms). Instead, he seems to have accepted the conclusions of Ruđer Bošković, who explained the qualities of matter as a result of an interplay of forces. One study of Nietzsche defines his fully developed concept of the will to power as "the element from which derive both the quantitative difference of related forces and the quality that devolves into each force in this relation" revealing the will to power as "the principle of the synthesis of forces." Of such forces Nietzsche said they could perhaps be viewed as a primitive form of the will. Likewise he rejected as a mere interpretation the view that the movement of bodies is ruled by inexorable laws of nature, positing instead that movement was governed by the power relations between bodies and forces.
Eternal return 
Eternal return (also known as "eternal recurrence") is a concept which posits that the universe has been recurring, and will continue to recur, in a self-similar form an infinite number of times across infinite time or space. It is a purely physical concept, involving no supernatural reincarnation, but the return of beings in the same bodies. The idea of eternal return occurs in a parable in Section 341 of The Gay Science, and also in the chapter "Of the Vision and the Riddle" in Thus Spoke Zarathustra, among other places. Nietzsche contemplates the idea as potentially "horrifying and paralyzing", and says that its burden is the "heaviest weight" imaginable ("das schwerste Gewicht"). The wish for the eternal return of all events would mark the ultimate affirmation of life, a reaction to Schopenhauer's praise of denying the will‐to‐live. To comprehend eternal recurrence in his thought, and to not merely come to peace with it but to embrace it, requires amor fati, "love of fate".
Alexander Nehamas writes in Nietzsche: Life as Literature of three ways of seeing the eternal recurrence: "(A) My life will recur in exactly identical fashion." This expresses a totally fatalistic approach to the idea. "(B) My life may recur in exactly identical fashion." This second view conditionally asserts cosmology, but fails to capture what Nietzsche refers to in The Gay Science, 341. Finally, "(C) If my life were to recur, then it could recur only in identical fashion." Nehamas shows that this interpretation exists totally independently of physics and does not presuppose the truth of cosmology. Nehamas draws the conclusion that if individuals constitute themselves through their actions, then they can only maintain themselves in their current state by living in a recurrence of past actions (Nehamas 153). Nietzsche's thought is the negation of the idea of a history of salvation.
Another concept important to an understanding of Nietzsche's thought is the Übermensch (translated variously as "overman", "superman", or "super-human"). Developing the idea of nihilism, Nietzsche wrote Thus Spoke Zarathustra, therein introducing the concept of a value-creating Übermensch, not as a project, but as an anti-project, the absence of any project. According to Lampert, "the death of God must be followed by a long twilight of piety and nihilism (II. 19; III. 8). [...] Zarathustra's gift of the overman is given to a mankind not aware of the problem to which the overman is the solution." Zarathustra presents the overman as the creator of new values, and he appears as a solution to the problem of the death of God and nihilism. The overman does not follow morality of common people since it favors mediocrity but instead rises above the notion of good and evil and above the herd. In this way Zarathustra proclaims his ultimate goal as the journey towards the state of overman. He wants a kind of spiritual evolution of self-awareness and overcoming of traditional views on morality and justice that stem from the superstition beliefs still deeply rooted or related to the notion of God and Christianity.
While interpretations of Nietzsche's overman vary wildly, here is one of his quotations from Thus Spoke Zarathustra (Prologue, §§3–4):
I teach you the overman. Man is something that shall be overcome. What have you done to overcome him?... All beings so far have created something beyond themselves; and do you want to be the ebb of this great flood, and even go back to the beasts rather than overcome man? What is ape to man? A laughing stock or painful embarrassment. And man shall be that to overman: a laughingstock or painful embarrassment. You have made your way from worm to man, and much in you is still worm. Once you were apes, and even now, too, man is more ape than any ape... The overman is the meaning of the earth. Let your will say: the overman shall be the meaning of the earth... Man is a rope, tied between beast and overman—a rope over an abyss ... what is great in man is that he is a bridge and not an end.
Zarathustra contrasts the overman with the last man of egalitarian modernity (most obvious example being democracy), an alternative goal which humanity might set for itself. The last man is possible only by mankind's having bred an apathetic creature who has no great passion or commitment, who is unable to dream, who merely earns his living and keeps warm. This concept appears only in Thus Spoke Zarathustra, and is presented as a condition that would render the creation of the overman impossible.
Some have suggested that the notion of eternal return is related to the overman since willing the eternal return of the same is a necessary step if the overman is to create new values, untainted by the spirit of gravity or asceticism. Values involve a rank-ordering of things, and so are inseparable from approval and disapproval; yet it was dissatisfaction that prompted men to seek refuge in other-worldliness and embrace other-worldly values. It could seem that the overman, in being devoted to any values at all, would necessarily fail to create values that did not share some bit of asceticism. Willing the eternal recurrence is presented as accepting the existence of the low while still recognizing it as the low, and thus as overcoming the spirit of gravity or asceticism. One must have the strength of the overman in order to will the eternal recurrence of the same; that is, only the overman will have the strength to fully accept all of his past life, including his failures and misdeeds, and to truly will their eternal return. This action nearly kills Zarathustra, for example, and most human beings cannot avoid other-worldliness because they really are sick, not because of any choice they made.
Reading and influence 
As a philologist, Nietzsche had a thorough knowledge of Greek philosophy. He read Immanuel Kant, Plato, John Stuart Mill, Arthur Schopenhauer and African Spir, who became his main opponents in his philosophy, and later Spinoza, whom he saw as his "precursor" in some respects but as a personification of the "ascetic ideal" in others. However, Nietzsche referred to Kant as a "moral fanatic", Plato as "boring", Mill as a "blockhead", and of Spinoza he said: "How much of personal timidity and vulnerability does this masquerade of a sickly recluse betray?".
Nietzsche's philosophy, while highly innovative and revolutionary, was indebted to many predecessors. While at Basel, Nietzsche offered lecture courses on the "Pre-Platonic Philosophers" for several years, and the text of this lecture series has been characterized as a "lost link" in the development of his thought. "In it concepts such as the will to power, the eternal return of the same, the overman, gay science, self-overcoming and so on receive rough, unnamed formulations and are linked to specific pre-Platonics, especially Heraclitus, who emerges as a pre-Platonic Nietzsche." The pre-Socratic Greek thinker Heraclitus was known for the rejection of the concept of being as a constant and eternal principle of universe, and his embrace of "flux" and incessant change. His symbolism of the world as "child play" marked by amoral spontaneity and lack of definite rules was appreciated by Nietzsche. From his Heraclitean sympathy, Nietzsche was also a vociferous detractor of Parmenides, who opposed Heraclitus and believed all world is a single Being with no change at all.
In his Egotism in German Philosophy, Santayana claimed that Nietzsche's whole philosophy was a reaction to Schopenhauer. Santayana wrote that Nietzsche's work was "an emendation of that of Schopenhauer. The will to live would become the will to dominate; pessimism founded on reflection would become optimism founded on courage; the suspense of the will in contemplation would yield to a more biological account of intelligence and taste; finally in the place of pity and asceticism (Schopenhauer's two principles of morals) Nietzsche would set up the duty of asserting the will at all costs and being cruelly but beautifully strong. These points of difference from Schopenhauer cover the whole philosophy of Nietzsche."
Nietzsche expressed admiration for 17th century French moralists such as La Rochefoucauld, Jean de La Bruyère and Vauvenargues, as well as for Stendhal. The organicism of Paul Bourget influenced Nietzsche, as did that of Rudolf Virchow and Alfred Espinas. Nietzsche wrote in a letter in 1867 that he was trying to improve his German style of writing with the help of Lessing, Lichtenberg and Schopenhauer. It was probably Lichtenberg (along with Paul Rée) whose aphoristic style of writing contributed to Nietzsche's own use of aphorism instead of an essay. Nietzsche early learned of Darwinism through Friedrich Albert Lange. Hippolyte Taine influenced Nietzsche's view on Rousseau and Napoleon. Notably, he also read some of the posthumous works of Charles Baudelaire, Tolstoy's My Religion, Ernest Renan's Life of Jesus and Fyodor Dostoyevsky's The Possessed. Nietzsche called Dostoevsky "the only psychologist from whom I have anything to learn." Harold Bloom has often claimed that the essays of Ralph Waldo Emerson had a profound and favourable influence on Nietzsche. While Nietzsche never mentions Max Stirner, the similarities in their ideas have prompted a minority of interpreters to suggest a relationship between the two. In 1861 Nietzsche wrote an enthusiastic essay on his "favorite poet", Friedrich Hölderlin, mostly forgotten at that time. He also expressed deep appreciation for Adalbert Stifter's Indian Summer, Lord Byron's Manfred and Mark Twain's The Adventures of Tom Sawyer.
Nietzsche's works did not reach a wide readership during his active writing career. However, in 1888 the influential Danish critic Georg Brandes aroused considerable excitement about Nietzsche through a series of lectures he gave at the University of Copenhagen. In the years after Nietzsche's death in 1900, his works became better known, and readers have responded to them in complex and sometimes controversial ways. Many Germans eventually discovered his appeals for greater individualism and personality development in Thus Spoke Zarathustra, but responded to them divergently. He had some following among left-wing Germans in the 1890s; in 1894–1895 German conservatives wanted to ban his work as subversive. During the late 19th century Nietzsche's ideas were commonly associated with anarchist movements and appear to have had influence within them, particularly in France and the United States. H. L. Mencken produced translations of Nietzsche's works that helped to increase knowledge of his philosophy in the United States. Nietzsche is known today as a precursor to expressionism, existentialism, and postmodernism.
W. B. Yeats and Arthur Symons described Nietzsche as the intellectual heir to William Blake. Symons went on to compare the ideas of the two thinkers in The Symbolist Movement in Literature while Yeats tried to raise awareness of Nietzsche in Ireland. A similar notion was espoused by W. H. Auden who wrote of Nietzsche in his New Year Letter (released in 1941 in The Double Man): "O masterly debunker of our liberal fallacies [...] all your life you stormed, like your English forerunner Blake". Nietzsche made an impact on composers during the 1890s. Writer on music Donald Mitchell notes that Gustav Mahler was "attracted to the poetic fire of Zarathustra, but repelled by the intellectual core of its writings." He also quotes Gustav himself, and adds that he was influenced by Nietzsche's conception and affirmative approach to nature, which Mahler presented in Third Symphony using Zarathustra's roundelay. Frederick Delius has produced a piece of choral music A Mass of Life based on a text of Thus Spoke Zarathustra, while Richard Strauss (who also based his Also sprach Zarathustra on the same book), was only interested in finishing "another chapter of symphonic autobiography". Famous writers and poets influenced by Nietzsche include André Gide, August Strindberg, Robinson Jeffers, Pío Baroja, D. H. Lawrence, Edith Södergran and Yukio Mishima.
Nietzsche was an early influence on the poetry of Rainer Maria Rilke. Knut Hamsun counted Nietzsche, along with Strindberg and Dostoyevsky as one of his primary influences. Author Jack London wrote that he was more stimulated by Nietzsche that by any other writer in the world. Critics have suggested that the character of David Grief in A Son of the Sun was based on Nietzsche. Nietzsche's influence on Muhammad Iqbal is most evidenced in Asrar-i-Khudi (The Secrets of the Self). Wallace Stevens was another reader of Nietzsche and elements of Nietzsche's philosophy were found throughout Harmonium. Olaf Stapledon was influenced by the idea of Übermensch and it is central theme in his books Odd John and Sirius. In Russia, Nietzsche has influenced Russian symbolism and figures such as Dmitry Merezhkovsky, Andrei Bely, Vyacheslav Ivanovich Ivanov and Alexander Scriabin have all incorporated or discussed parts of Nietzsche philosophy in their works. Thomas Mann's novel Death in Venice shows a use of Apollonian and Dionysian, and in Doctor Faustus Nietzsche was a central source for the character of Adrian Leverkühn. Hermann Hesse, similarly, in his Narcissus and Goldmund presents two main characters in the sense of Apollonian and Dionysian as the two opposite yet intertwined spirits. Painter Giovanni Segantini was fascinated by Thus Spake Zarathustra, and he drew an illustration for the first Italian translation of the book.
By World War I, Nietzsche had acquired a reputation as an inspiration for both right-wing German militarism and leftist politics. German soldiers received copies of Thus Spoke Zarathustra as gifts during World War I. The Dreyfus Affair provides a contrasting example of his reception: the French anti-semitic Right labelled the Jewish and Leftist intellectuals who defended Alfred Dreyfus as "Nietzscheans". Nietzsche had a distinct appeal for many Zionist thinkers around the start of the 20th century most notable being Ahad Ha'am, Hillel Zeitlin, Micha Josef Berdyczewski, A. D. Gordon and Martin Buber who went so far as to extoll Nietzsche as a "creator" and "emissary of life". Chaim Weizmann was a great admirer of Nietzsche; the first president of Israel sent Nietzsche's books to his wife, adding a comment in a letter that "This was the best and finest thing I can send to you". Israel Eldad, the ideological chief of the Stern Group that fought the British in Palestine in the 1940s, wrote about Nietzsche in his underground newspaper and later translated most of Nietzsche's books into Hebrew. Eugene O'Neill remarked that Zarathustra influenced him more that any other book he ever read. He also shared Nietzsche's view of tragedy. Plays The Great God Brown and Lazarus Laughed are an example of Nietzsche's influence on O'Neill. Nietzsche's influence on the works of Frankfurt School philosophers Max Horkheimer and Theodor W. Adorno can be seen in the popular Dialectic of Enlightenment. Adorno summed up Nietzsche's philosophy as expressing the "humane in a world in which humanity has become a sham".
Nietzsche's growing prominence suffered a severe setback when his works became closely associated with Adolf Hitler and the German Reich. Many political leaders of the twentieth century were at least superficially familiar with Nietzsche's ideas, although it is not always possible to determine whether they actually read his work. Hitler, for example, probably never read Nietzsche and, if he did, his reading was not extensive, although he was a frequent visitor to the Nietzsche museum in Weimar and did use expressions of Nietzsche's, such as "lords of the earth" in Mein Kampf. The Nazis made selective use of Nietzsche's philosophy. Mussolini, Charles de Gaulle and Huey P. Newton read Nietzsche. Richard Nixon read Nietzsche with "curious interest," and his book Beyond Peace might have taken its title from Nietzsche's book Beyond Good and Evil which Nixon read beforehand. Bertrand Russell wrote that Nietzsche had exerted great influence on philosophers and on people of literary and artistic culture, but warned that the attempt to put Nietzsche's philosophy of aristocracy into practice could only be done by an organization similar to the Fascist or the Nazi party.
A decade after World War II, there was a revival of Nietzsche's philosophical writings thanks to exhaustive translations and analyses by Walter Kaufmann and R.J. Hollingdale. Others, well known philosophers in their own right, wrote commentaries on Nietzsche's philosophy, including Martin Heidegger, who produced a four-volume study and Lev Shestov who wrote a book called Dostoyevski, Tolstoy and Nietzsche where he portrays Nietzsche and Dostoyevski as the "thinkers of tragedy". Georg Simmel compares Nietzsche's importance to ethics to that of Copernicus for cosmology. Sociologist Ferdinand Tönnies read Nietzsche avidly from his early life, and later frequently discussed many of his concepts in his own works. Nietzsche has influenced philosophers such as Martin Heidegger, Jean-Paul Sartre, Oswald Spengler, George Grant, Emil Cioran, Albert Camus, Ayn Rand, Jacques Derrida, Leo Strauss, Max Scheler, Michel Foucault and Bernard Williams. Camus described Nietzsche as "the only artist to have derived the extreme consequences of an aesthetics of the absurd". Paul Ricœur called Nietzsche one of the masters of the "school of suspicion", alongside Karl Marx and Sigmund Freud.
