A couple years ago, Brian Leiter came out with Nietzsche on Morality, which discusses Nietzsche's Genealogy of Morality. Last year, he and I edited Nietzsche and Morality, a collection of essays (I've linked to the review in the previous post).
I'm kind of wondering what other titles involving "Nietzsche" and "Morality" are in Brian's future and mine. Maybe Nietzsche or Morality -- I imagine the disjunction being exclusive. Sadly, Nietzsche if Morality is ungrammatical and probably suggestive of an incorrect view, as is Nietzsche if and only if Morality. But there's more opportunity in going beyond the truth-functional connectives. Consider Nietzsche Underneath Morality, Nietzsche Slightly To the Right Of Morality, and the like. Clearly we have many excellent publications ahead of us before we exhaust this productive line of research.
