I'm confused. If this article promotes pluralistic moral reduction, why does Luke M. make a statement that sounds reductionaly singular rather than plural? I mean this statement here:

But moral terms and value terms are about what we want.

Isn't this a reduction of morality to a single thing, specifically, "what we want", i.e., desire?

Isn't this defining morality as the practice of acting on our desires? And does not this definition contradict other definitions/reductions?
