After you’ve gotten your chuckles and inspiration from Revere’s Freethinker Sunday Sermonette, check out Russell Blackford’s most recent post on moral scepticism. A sample:
The plausible meta-ethical positions seem to be a group of sophisticated moral relativist theories — the sort of position I associate with Gilbert Harman, David Wong, Neil Levy, Max Hocutt, and others — and the error theories (moral scepticism) of people like JL Mackie, Richard Garner, Richard Joyce, and Joshua Greene. There are various other positions in the same ballpark, such as the sophisticated non-cognitivism of Simon Blackburn. I am sometimes irritated when other philosophers assume that the only theory in this sort of ballpark is the popular but vulgar kind of moral relativism that we are all taught to avoid in first-year ethics courses.
