Historically, atheism has rarely been a blanket denial of the sacred per se but has nearly always rejected a particular conception of the divine. At an early stage of their history, Christians and Muslims were both called “atheists” by their pagan contemporaries, not because they denied the reality of God but because their conception of divinity was so different that it seemed blasphemous. Atheism is therefore parasitically dependent on the form of theism it seeks to eliminate and becomes its reverse mirror image. Classical Western atheism was developed during the nineteenth and early twentieth centuries by Feuerbach, Marx, Nietzsche, and Freud, whose ideology was essentially a response to and dictated by the theological perception of God that had developed in Europe and the United States during the modern period. The more recent atheism of Richard Dawkins, Christopher Hitchens, and Sam Harris is rather different, because it has focused exclusively on the God developed by the fundamentalisms, and all three insist that fundamentalism constitutes the essence and core of all religion. This has weakened their critique, because fundamentalism is in fact a defiantly unorthodox form of faith that frequently misrepresents the tradition it is trying to defend.But the “new atheists” command a wide readership, not only in secular Europe but even in the more conventionally religious United States. The popularity of their books suggests that many people are bewildered and even angered by the God concept they have inherited.
