If Enlightenment thinking (see Optimistic Humanism) leads to the death of God, Nihilism, according to Nietzsche saw ‘the death of his murderer’. Nihilism rejects absolutes and objective meaning.
The Human race is destined to progress. This idea has come to dominate modern thought. Man will be his own salvation through science and democracy. Belief in God is not only seen as irrelevant, it is positively harmful. Enlightenment thinking which began 300 years ago has come to dominate the Western World. Its ideas were formally codified in the 1933 Humanist Manifesto.
