The biological roots of morality
Posted on July 6, 2011
The Chronicle of Higher Education has a great essay on the “neurophilosophical” work being done by Patricia Churchland, professor emerita of philosophy at the University of California at San Diego. Take a look:
Churchland … has been best known for her work on the nature of consciousness. But now, with a new book, Braintrust: What Neuroscience Tells Us About Morality (Princeton University Press), she is taking her perspective into fresh terrain: ethics. And the story she tells about morality is, as you’d expect, heavily biological, emphasizing the role of the peptide oxytocin, as well as related neurochemicals.
“I have long been interested in the origins of values,” she says, the day after lecturing on that topic at the nearby American Museum of Natural History. “But I would read contemporary ethicists and just feel very unsatisfied. It was like I couldn’t see how to tether any of it to the hard and fast. I couldn’t see how it had anything to do with evolutionary biology, which it has to do, and I couldn’t see how to attach it to the brain.”
