Even that great atheist and scientist Bertrand Russell would disagree with your naivete.
So Nietzsche is the great scientist. Well show me where Russell is wrong here.
Nietzsche alludes habitually to ordinary human beings as the “bungled and botched,” and sees no objection to their suffering if it is necessary for the production of a great man. Thus the whole importance of the period from 1789 to 1815 is summed up in Napoleon: “The Revolution made Napoleon possible: that is its justification…”
It is necessary for higher men to make war upon the masses, and resist the democratic tendencies of the age, for in all directions mediocre people are joining hands to make themselves masters… He regards compassion as a weakness to be combated… He prophesied with a certain glee an era of great wars; one wonders whether he would have been happy if he had lived to see the fulfillment of his prophecy.
There is a great deal in Nietzsche that must be dismissed as merely megalomaniac… It is obvious that in his day-dreams he is a warrior, not a professor; all the men he admires were military. His opinion of women, like every man’s, is an objectification of his own emotion towards them, which is obviously one of fear. “Forget not thy whip”–but nine women out of ten would get the whip away from him, and he knew it, so he kept away from women, and soothed his wounded vanity with unkind remarks.
He condemns Christian love because he thinks it is an outcome of fear… It does not occur to Nietzsche as possible that a man should genuinely feel universal love, obviously because he himself feels almost universal hatred and fear, which he would fain disguise as lordly indifference. His “noble” man–who is himself in day-dreams–is a being wholly devoid of sympathy, ruthless, cunning, concerned only with his own power. King Lear, on the verge of madness, says: “I will do such things–what they are yet I know not–but they shall be the terror of the earth.” This is Nietzsche’s philosophy in a nutshell.
