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.

I am one of the few people I know of who has argued in print that torture may be an ethical necessity in our war on terror.

Either our wills are determined by prior causes and we are not responsible for them, or they are the product of chance and we are not responsible for them.

The idea, therefore, that religious faith is somehow a sacred human convention—distinguished, as it is, both by the extravagance of its claims and by the paucity of its evidence—is really too great a monstrosity to be appreciated in all its glory. Religious faith represents so uncompromising a misuse of the power of our minds that it forms a kind of perverse, cultural singularity—a vanishing point beyond which rational discourse proves impossible.
