Episode 145, The Mystery of Morality: Live in London (Part I - The Debate)

July 13, 2025·1 hr 15 min·7 clips

Peter Singer argues that reflective equilibrium leads to relativism, challenging Richard Swinburne's view on moral progress.

The question is old. The live debate starts with the basic split: maybe morality is part of reality, or maybe people build it later to organize instinct, emotion, and social pressure. It gets practical fast. If other animals and artificial intelligence can count morally, then morality is not just a tidy metaphysical preference. It decides who, or what, gets considered at all. One speaker is especially hard on intuition. He uses past condemnation of same-sex relationships as a warning against treating inherited feelings as evidence. The example is meant to bite. Evolution may help explain why some societies discouraged those relationships, but explanation does not make the judgment right. Bentham enters as the useful troublemaker here: a utilitarian willing to criticize making sexual orientation a crime before the surrounding culture was ready for it. So sentiment is not enough. On this view, ethical reform needs principles about harm, interference, and the quality of life in a community. Fraser turns the screw from another angle. She accepts that emotional and motivational intuitions have force, then asks what happens when those intuitions vary across cultures and eras. Maybe ethics begins when people meet outsiders and realize their moral instincts are not universal. Near the end, pleasure and pain are defined by whether an experience is wanted or unwanted while it is happening. Clean, maybe too clean. The debate keeps the pressure open, then sends it to the audience with a dry joke about locked doors.
