Beyond Good and Evil is a book by philosopher Friedrich Nietzsche. It draws on and expands the ideas of his previous work, Thus Spoke Zarathustra, but with a more critical and polemical approach. In Beyond Good and Evil, Nietzsche accuses past philosophers of lacking critical sense and blindly accepting dogmatic premises in their consideration of morality. Specifically, he accuses them of founding grand metaphysical systems upon the faith that the good man is the opposite of the evil man, rather than just a different expression of the same basic impulses that find more direct expression in the evil man. The work moves into the realm "beyond good and evil" in the sense of leaving behind the traditional morality which Nietzsche subjects to a destructive critique in favor of what he regards as an affirmative approach that fearlessly confronts the perspectival nature of knowledge and the perilous condition of the modern individual.
Of the four "late-period" writings of Nietzsche, Beyond Good and Evil most closely resembles the aphoristic style of his middle period. In it he exposes the deficiencies of those usually called "philosophers" and identifies the qualities of the "new philosophers": imagination, self-assertion, danger, originality, and the "creation of values". He then contests some of the key presuppositions of the old philosophic tradition like "self-consciousness," "knowledge," "truth," and "free will", explaining them as inventions of the moral consciousness. In their place he offers the "will to power" as an explanation of all behavior; this ties into his "perspective of life", which he regards as "beyond good and evil", denying a universal morality for all human beings. Religion and the master and slave moralities feature prominently as Nietzsche re-evaluates deeply held humanistic beliefs, portraying even domination, appropriation and injury to the weak as not universally objectionable.

All the efforts of several hundred thousand people, crowded in a small space, to disfigure the land on which they lived; all the stone they covered it with to keep it barren; how so diligently every sprouting blade of grass was removed; all the smoke of coal and naphtha; all the cutting down of trees and driving off of cattle could not shut out the spring, even from the city. The sun was shedding its light; the grass, revivified, was blooming forth, where it was left uncut, not only on the greenswards of the boulevard, but between the flag-stones, and the birches, poplars and wild-berry trees were unfolding their viscous leaves; the limes were unfolding their buds; the daws, sparrows and pigeons were joyfully making their customary nests, and the flies were buzzing on the sun-warmed walls. Plants, birds, insects and children were equally joyful. Only men—grown-up men—continued cheating and tormenting themselves and each other. People saw nothing holy in this spring morning, in this beauty of God's world—a gift to all living creatures—inclining to peace, good-will and love, but worshiped their own inventions for imposing their will on each other.
The joy of spring felt by animals and men did not penetrate the office of the county jail, but the one thing of supreme importance there was a document received the previous evening, with title, number and seal, which ordered the bringing into court for trial, this 28th day of April, at nine o'clock in the morning, three prisoners—two [Pg 6]women and one man. One of the women, as the more dangerous criminal, was to be brought separately. So, in pursuance of that order, on the 28th day of April, at eight o'clock in the morning, the jail warden entered the dingy corridor of the woman's ward. Immediately behind him came a woman with weary countenance and disheveled gray hair, wearing a crown-laced jacket, and girdled with a blue-edged sash. She was the matron.
"You want Maslova?" she asked the warden, as they neared one of the cells opening into the corridor.
The warden, with a loud clanking of iron, unlocked and opened the door of the cell, releasing an even fouler odor than permeated the corridor, and shouted:
"Maslova to the court!" and again closing the door he waited for her appearance.
The fresh, vivifying air of the fields, carried to the city by the wind, filled even the court-yard of the jail. But in the corridor the oppressive air, laden with the smell of tar and putrescence, saddened and dejected the spirit of every new-comer. The same feeling was experienced by the jail matron, notwithstanding she was accustomed to bad air. On entering the corridor she suddenly felt a weariness coming over her that inclined her to slumber.
There was a bustling in the cell; women's voices and steps of bare feet were heard.
"Hurry up, Maslova! Come on, I say!" shouted the warden into the cell-door. [more]
