Expanding on his ideas from Thus Spoke Zarathustra, this influential text undermines the assumptions of traditional morality and encourages us to think more critically about the world in which we live. Nietzsche considers past philosophers and religious leaders from Socrates to Descartes to Schopenhauer with a critical and pessimistic eye. Questioning the blind following of religious faith, he examines the deeper question of who is truly good or evil.
