Multilevel or gene level perspectives: Which has the best explanatory power for our moral sense?
Gallery
Charles Darwin proposed group selection to explain how “altruistic” behaviors toward others and self-sacrifice for the group, which could easily be taken to be counterexamples to his theory of evolution, might instead be examples of its explanatory power. He observed … Continue reading

There is a contest, see ReThink Prize, to compose a secular replacement for the Ten Commandments. I like this notion. Secular people seek reliable moral guidance just like religious people do, but perhaps from different sources. Could there actually come … Continue reading
