Michael Horner and Massimo Pigliucci debate whether morality must come from a higher power: part 1, part 2.

The audio has problems, so you’ll have to crank it up at times. The debate begins about 6 minutes in.

Michael Horner argues that morality must come from a higher power (God) and that we have morals, and that we know morals exist, which proves the existence of God. Massimo Pigliucci argues that morality is very real, but exists only in the context of humanity as a combined genetic and social concept.
