Beyond Good And Evil. Beyond Good and Evil: Prelude to a Future Philosophy is a book written by philosopher Friedrich Nietzsche in 1886. It builds on and expands on the concepts explored in his previous work, Thus Spoke Zarathustra, but takes a more critical and polemical tone. Nietzsche accuses previous philosophers of lacking critical awareness and mindlessly adopting dogmatic premises in their examinations of morality in Beyond Good and Evil. He accuses them specifically of establishing vast metaphysical systems on the belief that the good man is the polar opposite of the evil man, rather than a different expression of the same fundamental impulses that manifest more directly in the evil man. The work enters the realm “beyond good and evil” in the sense that Nietzsche abandons traditional morality in favor of what he views as an affirmative approach that confronts boldly the perspectival nature of knowledge and the precarious position of the modern individual.
