Leah Libresco, a fixture at the Patheos portal for atheists, is leaving that spot, on the basis that she’s no longer qualified:
I’ve heard some explanations that try to bake morality into the natural world by reaching for evolutionary psychology. They argue that moral dispositions are evolutionarily triumphant over selfishness, or they talk about group selection, or something else. Usually, these proposed solutions radically misunderstand a) evolution b) moral philosophy or c) both. I didn’t think the answer was there.
And thinking it over further, she decided that the question wasn’t “Where?” but “Who?”
I believed that the Moral Law wasn’t just a Platonic truth, abstract and distant. It turns out I actually believed it was some kind of Person, as well as Truth. And there was one religion that seemed like the most promising way to reach back to that living Truth. I asked my friend what he suggest we do now, and we prayed the night office of the Liturgy of the Hours together (I’ve kept up with that since). Then I suggested hugs and playing Mumford and Sons really, really loudly.
