I'm concerned that replacing ethics with moral psychology would be falling for a naive is/ought fallacy: just because most people's psychological makeup makes them consider morality in a certain way does not make those moral intuitions correct.

I don't think Luke would disagree with this statement. The point of learning moral psychology, as I understand it, is not to adopt moral psychology as moral philosophy; it's to understand where moral intuitions come from. Luke doesn't want philosophers studying intuitionist moral philosophy, as I understand it, because it doesn't provide an accurate account of how people actually make moral decisions in practice.

You've also left out any political theory from your syllabus.

My understanding is that there is a standing agreement on LW not to discuss politics; see the Politics is the Mind-Killer sequence.

These concepts aren't easily reducible to a naturalized cognitivist wordview because they deal with transpersonal phenomena.

Can you elaborate on what you mean by this? (I am not sure exactly what you mean by "a naturalized cognitivist worldview" or by "transpersonal phenomena.")
