Throughout the history of philosophy, many philosophers have made profound breaks in morals, knowledge, thinking, state, religion. Nietzsche is also one of the "prophets of extremity" that makes these deep breaks in all aspects of thinking. Nietzsche criticizes the Western’s metaphysics thinking tradition in various ways. This criticism is especially rooted in the expression "God is dead". The death of God is vital both for understanding the basic structure of modern society and for understanding Nietzsche’s perception of the Christian morality. The understanding of Christian morality has transformed some concepts negatively such as good, beautiful, truth which are fundamental to life. The man who can face this transformation is the overman. Because the overman exceed himself by removing all the worthlessness from the value and by doing so the overman affirms life. Nietzsche says that Christian morality is based on nihilistic forms. As the forms of nihilism such as ressentiment and guilty conscience can only be overcome by a new way of thinking that is an effective thought prevails. This way of thinking is extremely important in terms of opening new paths to "thinking". Moreover, the expression of "God is dead" uncover what God means to Nietzsche via investigating that expression. Nietzsche's declaration of the death of God is a clear indication of he’s believe in the natural Gods of the Greeks as opposed to the anti-natural God of Christianity.
