Beyond Good and Evil

Beyond Good and Evil: Prelude to a Philosophy of the Future is a book by philosopher Friedrich Nietzsche that expands the ideas of his previous work, Thus Spoke Zarathustra, with a more critical and polemical approach. It was first published in 1886.
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.
