In fact we're forced to give up the idea that evil or good even exists at all. It is merely an imposition of a moral category on something that has no innate moral substance at all. Nothing is ultimately bad. Nothing is deplorable. Nothing is tragic or worthy of blame.
Nothing is ultimately good, honorable, noble, or worthy of praise.
It's all lost in a twilight zone of moral nothingness. Moral language becomes incoherent, which is precisely what this article suggests. A final observation. There's an interesting paragraph towards the end of the article and it reads like this referring to the Episcopal Church Foundation and other Christian concerns that are looking at this whole issue of scientific evidence for a natural tendency for those behaviors that we heretofore considered sinful. These theologians are looking at the scientific evidence to rethink their idea of sin.
