(My latest MercatorNet column looks at an attempt to refound morality on a totally materialist basis: commonsense notions of the mind must be abandoned in favor of a purely brain-based approach because we are our neurons:
Churchland is partial to a theory that morality originates in the oxytocin-vasopressin network in mammals. One outcome is stunners like this: “The social life of humans, whether in hunter-gatherer villages, farming towns, or cities, seems to be even more complex than that of baboons or chimpanzees.”
Now, why in the world would that be? We never get a clear idea how Churchland think morality works, though we do get more than a glimpse of her politics.
