It seems profoundly unlikely that we will heal the divisions in our world simply by multiplying the opportunities for interfaith dialogue. The endgame for civilization cannot be mutual tolerance of patent irrationality. While all parties to liberal religious discourse have agreed to tread lightly over those points where their worldviews would otherwise collide, these very points remain perpetual sources of conflict for their coreligionists. Political correctness, therefore, does not offer an enduring basis for human cooperation. If religious war is ever to become unthinkable for us, in the way that slavery and cannibalism seem poised to, it will be a matter of our having dispensed with the dogma of faith.
When we have reasons for what we believe, we have no need of faith; when we have no reasons, or bad ones, we have lost our connection to the world and to one another. Atheism is nothing more than a commitment to the most basic standard of intellectual honesty: One’s convictions should be proportional to one’s evidence. Pretending to be certain when one isn’t--indeed, pretending to be certain about propositions for which no evidence is even conceivable--is both an intellectual and a moral failing. Only the atheist has realized this. The atheist is simply a person who has perceived the lies of religion and refused to make them his own.
