Nietzsche’s critique of Christianity is at least in some of its aspects part of a much larger undertaking that one might call a critique of Weltanschauungen, a critique of “world views.” The “world view” that he writes about the most is Christianity, because it has had a particularly fateful importance for the Western world. Continuous with that we find an analysis of “nihilism.” What interests Nietzsche beyond nihilism is possible attitudes that man might adopt towards an absurd world—again a theme that you find in Heidegger, Sartre and Camus.1
