This BBC radio program almost passed by without me noticing. I put this down to its unpromising title: Thought Experiments. In it, Oxford philosopher, Janet Radcliffe Richards explains how experiments inspired by evolutionary thinking are shedding light on moral attitudes and how people make moral decisions. The program should be available for listening to until Sunday 5th July, but there is a program transcript here, which should be available permanently. I feel the need to do some reading in this area now.
