Sounder quoted:
According to Schroeder, Nietzsche's fully developed critique of morality in Beyond Good and Evil (1886) and On the Genealogy of Morality (1887) leaves the reader in no doubt that Nietzsche saw the destruction of the most basic moral principles - including the fundamental moral obligation not inflict gratuitous harm on others - as the only position consistent with a genuine rejection of God. According to Nietzsche, traditional morality was essentially a product of Jewish, and subsequently Christian, resentment against the original aristocratic values of strength, pride, and hardness of heart of their pagan political masters.[9]Nietzsche traces the Judeo-Christian moral principles of non-violence, impartiality and altruism to the particular group interests of the subordinated Jews and Christians.[10]Consequently, since traditional morality is merely the product of particular group interests, it loses its claim to universal validity.[11]
Schroeder notes that having exposed Judeo-Christian egalitarianism and universalism as a mere disguise for the promotion of their particular interests, Nietzsche promotes a particularist morality for the 'strong'. Hardness of heart, cruelty, and the will to annihilate the inferior sort of human beings constitute the basic components of his 'ethics' which he proposes should replace the old (religious) morality.[12] As Schroeder further observes, Nietzsche did not stop at seeking the physical annihilation of those human beings whom he considered the detritus of life ('Ausschuss und Abfall des Lebens').[13] Like De Sade, the harming - and also the killing - of supposed inferiors is not only allowed by Nietzsche but positively encouraged, for the sake of the improvement of the race.
Sounder, this really answers nothing. He was deeply iconoclastic and pretty much without peer in terms of sheer brilliance. The sketch above is a caricature of him, long ago discredited, and largely the product of a false presentation of his work by his sister during the period of his life when he was institutionalized, and the Nazis' cultish glorification of a highly selective sample of his output. It was these distortions that made it into mainstream accounts of Nietzsche. See the article below.
Nietzsche and Fascism: On the Uses and Abuses of Philosophy
Introduction
Jacob Golomb and Robert S. Wistrich
Nietzsche and fascism? Is it not almost a contradiction in terms? What can Nietzsche have in common with this murderous ideology? The central ideal of Nietzsche's philosophy was the individual and his freedom to shape his own character and destiny. The German philosopher was frequently described as the "radical aristocrat" of the spirit because he abhorred mass culture and strove to cultivate a special kind of human being, the Übermensch, endowed with exceptional spiritual and mental qualities. What can such a thinker have in common with National Socialism's manipulation of the masses for chauvinistic goals that swallowed up the personalities, concerns, and life of the individual?
