What makes today’s popular atheism so depressing is neither its conceptual boorishness nor its self-righteousness but simply its cultural inevitability. It is the final, predictable, and unsurprisingly vulgar expression of an ideological tradition that has, after many centuries, become so pervasive and habitual that most of us have no idea how to doubt its premises or how to avert its consequences. This is a fairly sad state of affairs, because those consequences have at times proved quite terrible.
