Nietzsche saw nihilism as the outcome of repeated frustrations in the search for meaning. He diagnosed nihilism as a latent presence within the very foundations of European culture, and saw it as a necessary and approaching destiny. The religious worldview had already suffered a number of challenges from contrary perspectives grounded in philosophical skepticism, and in modern science's evolutionary and heliocentric theory. Nietzsche saw this intellectual condition as a new challenge to European culture, which had extended itself beyond a sort of point-of-no-return. Nietzsche conceptualizes this with the famous statement "God is dead", which first appeared in his work in section 108 of The Gay Science, again in section 125 with the parable of "The Madman", and even more famously in Thus Spoke Zarathustra. The statement, typically placed in quotation marks, accentuated the crisis that Nietzsche argued that Western culture must face and transcend in the wake of the irreparable dissolution of its traditional foundations, moored largely in classical Greek philosophy and Christianity. In aphorisms 55 and 56 of Beyond Good and Evil, Nietzsche talks about the ladder of religious cruelty that suggests how Nihilism emerged from the intellectual conscience of Christianity. Nihilism is sacrificing the meaning "God" brings into our lives, for "matter and motion", physics, "objective truth." In aphorism 56, he explains how to emerge from the utter meaninglessness of life by reaffirming it through the Nietzsche's ideal of Eternal Return.
