“Nihilism stands at the door,” wrote Nietzsche. “Whence comes this uncanniest of all guests?” The year was 1885 or 1886, and Nietzsche was writing in a notebook whose contents were not intended for publication. The discussion of nihilism ─ the sense that it is no longer obvious what our most fundamental commitments are, or what matters in a life of distinction and worth, the sense that the world is an abyss of meaning rather than its God-given preserve ─ finds no sustained treatment in the works that Nietzsche prepared for publication during his lifetime. But a few years earlier, in 1882, the German philosopher had already published a possible answer to the question of nihilism’s ultimate source. “God is dead,” Nietzsche wrote in a famous passage from “The Gay Science.” “God remains dead. And we have killed him.”
There is much debate about the meaning of Nietzsche’s famous claim, and I will not attempt to settle that scholarly dispute here. But at least one of the things that Nietzsche could have meant is that the social role that the Judeo-Christian God plays in our culture is radically different from the one he has traditionally played in prior epochs of the West. For it used to be the case in the European Middle Ages for example ─ that the mainstream of society was grounded so firmly in its Christian beliefs that someone who did not share those beliefs could therefore not be taken seriously as living an even potentially admirable life. Indeed, a life outside the Church was not only execrable but condemnable, and in certain periods of European history it invited a close encounter with a burning pyre.
Whatever role religion plays in our society today, it is not this one. For today’s religious believers feel strong social pressure to admit that someone who doesn’t share their religious belief might nevertheless be living a life worthy of their admiration. That is not to say that every religious believer accepts this constraint. But to the extent that they do not, then society now rightly condemns them as dangerous religious fanatics rather than sanctioning them as scions of the Church or mosque. God is dead, therefore, in a very particular sense. He no longer plays his traditional social role of organizing us around a commitment to a single right way to live. Nihilism is one state a culture may reach when it no longer has a unique and agreed upon social ground.
