Are there moral facts? If so, are they objective? Where do they come from? Do we have reason to think - or doubt - that our immediate ethical intuitions tell what us they are?
These are the questions I discuss this week with professor Michael Huemer. The metaethical landscape can be split up as follows: realists (those who think there are objective ethical facts) and anti-realists (those who don't). Realists, in turn, fall into two further camps: naturalists, who think objective ethical facts can be reduced to descriptive facts about the world; and ethical intuitionists, who think ethical facts (or "evaluative" facts) are of a different sort and cannot be reduced to descriptive facts. As Huemer puts it, ethical intuitionists argue that ethical facts have a different type of ontology. We go on to discuss the reasons we should trust our ethical intuitions to reveal moral facts, why ethical intuitions seem shakier than perceptual ones, and what the source of moral facts is. Finally, Huemer gives us a teaser for his upcoming book, Paradox Lost, in which he claims to solve ten famous paradoxes, including the Liar, Sorites, Newcomb's, and the Sleeping Beauty problem.
