I've posted the penultimate draft of the essay for the forthcoming Oxford Handbook of Moral Psychology being edited by John Doris (Wash U/St. Louis) and Manuel Vargas (UC San Diego); it is a kind of precis of my forthcoming Moral Psychology with Nietzsche that OUP will publish in 2019 (that book both offers a reading of Nietzsche's moral psychology and a sustained philosophcial and empirical defense of it).
