The atheist liberation movement of recent years has featured efforts to explain away the global prevalence of religion as totally the result of social forces that perhaps got imprinted into humanity’s evolutionary biology.

The tables are turned in a new book, “The Evolution of Atheism: The Politics of a Modern Movement” (Oxford University Press). Journalists: It’s heady stuff to be a hook for news treatment, but worth the effort.

The book analyzes atheistic causes in North America over the past century, including its internal schisms and contradictions. The work is based on Canadian author Stephen LeDrew’s doctoral dissertation at York University in Ontario and post-doctoral study in Sweden at Uppsala University’s Center for the Study of Religion and Society.

Religion newswriters are well aware that those aggressive “New Atheists” sometimes suggest faith is not just stupid but morally evil or a sort of mental illness, such that parents should be forbidden to infect their own children with it. Journalists may be surprised to learn that for LeDrew and others, this sort of anti-religion thinking is outdated and “utterly out of sync with contemporary social science.”

Social scientists long embraced the “secularization thesis,” according to which religion will inevitably decline as modern science advances. But now, says LeDrew, many acknowledge that scenario was “a product of ideology” rather than empirical fact. Thus, the New Atheism could be seen as a promotional effort to defend against “a perceived failure of secularism in practice in late modern society.”
