According to Nietzsche, philosophers of the past lacked critical sense and simply accepted the various dogmatic premises regarding morality. He claims they had relied on the faith that good men and evil men are polar opposites instead of simply different expressions of the same basic drives that the evil men simply allow to flow through them without regard to morality. In this, one of his major works, he explores the nature of morality as it relates to good and evil. It is required reading for anyone with even a passing interest in philosophy.
