In Beyond Good and Evil, Neitzsche explores what society might look like if we were brave enough to emerge fully from the shadow of the Christian God proposing that God is dead—and that "philosophers of the future" must construct a new morality to replace the Christian one. Nietzsche bases his understanding of our current morality in history and psychology, tracing its roots through to Christianity. Claiming that the systems of many illustrious philosophers are mere fabrications created only to express the unconscious drives of their authors, Nietzsche moves past traditional ideas of morality that position "good" against "evil" and explores how subconscious instincts inform human behaviour.
