Beyond Good and Evil, Prelude to a Philosophy of the Future, by Friedrich Nietzsche expands on the ideas of his work, Thus Spoke Zarathustra, takes an approach from a more critical, polemical direction. In Beyond Good and Evil, Nietzsche accuses past philosophers of lacking critical sense and blindly accepting Judeo-Christian premises in their consideration of morality. The work moves 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. Friedrich Wilhelm Nietzsche was a 19th-century German philosopher, poet, composer and classical philologist. He wrote critical texts on religion, morality, contemporary culture, philosophy and science, displaying a fondness for metaphor, irony and aphorism.
