Beyond Good and Evil by Friedrich Nietzsche

Beyond Good and Evil (German: Jenseits von Gut und Böse; subtitled "Prelude to a Philosophy of the Future" (German: Vorspiel einer Philosophie der Zukunft)) is a book by the philosopher Friedrich Nietzsche, first published in 1886.
Beyond Good and Evil takes up and expands on the ideas of his previous work, Thus Spoke Zarathustra, but approached from a more critical, polemical direction.
In Beyond Good and Evil, Friedrich Nietzsche accuses past philosophers of lacking critical sense and blindly accepting Judeo-Christian premises in their consideration of morality. The work moves into the realm "beyond good and evil" in the sense of leaving behind the traditional morality which Friedrich Nietzsche subjects to a destructive critique in favour 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 Friedrich 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.
