“if you are a skeptical philosopher who subjects everything to a strict test of reason, God is only one of many things that don’t make the grade. A philosopher engaged in radical doubt ends up with only sense data and the rules of logic on the table—or rather, on that configuration of sense data that we call a “table.” But that’s all, folks. Gone with God are also all moral principles; in the end there is no rational way to prove that any action is good or bad, so off the table morality should go, too. Ultimately, we take our belief in good and evil on faith, pretty much the same way some people take their belief in God. So the question is: Are we willing to throw out our faith in morality along with our faith in God? After all, one is as irrational as the other. And if not—if we are willing to make an exception to our faith-scuttling in the case of moral principles—why exactly don’t we also make an exception in the case of the existence of God?”
