Although many things can be said in criticism of religious faith, there is no discounting its power. Millions among us, even now, are quite willing to die for our unjustified beliefs, and millions more, it seems, are willing to kill for them.

It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed (Aquinas).

We rely on faith only in the context of claims for which there is no sufficient sensory or logical evidence.

The problem is that religion tends to give people bad reasons to be good.

Everyone who has eyes to see can see that if the God of Abraham exists, He is an utter psychopath--and the God of Nature too. If you can't see these things just by looking, you have simply closed your eyes to the realities of our world.

I think there are universal principles that we should want to understand, but that are not necessarily good for us. We could recognise universal propensities which current cultures can't fully eradicate, which we would want to eradicate if we could. Let's say, a tendency for tribal violence. Or racism.

The moral truth here is obvious: anyone who feels that the interests of a blastocyst just might supersede the interests of a child with a spinal cord injury has had his moral sense blinded by religious metaphysics.
