What is "the Kantian ethics/epistemology/metaphysics/aesthetics grid"?

Dana Villa is a political theorist in the Political Science Department at the University of Notre Dame. In a review essay of some recent books on Nietzsche, he concludes with the following statement:

Nietzsche’s critique [of Christian-bourgeois civilization], however, fails to fit the Kantian ethics/epistemology/metaphysics/aesthetics grid—the very grid that
guides the analytic re-constructor. The result is that even the best analytic
Nietzsche literature (and Reginster’s book certainly falls into that category)
will tend to leave out the essential.

"Analytic" is, of course, a code word for a commentator who knows some philosophy and treats Nietzsche as a philosopher who has arguments and evidence. But put that to one side: what sense can be given to "the Kantian ethics/epistemology/metaphysics/aesthetics grid" such that it is true that, for example, Reginster or me is committed to it, and that in virtue of that, are missing something "essential"? The answer may be (as I suspect) no sense at all, and that like talk of "analytic" this is really just code for something else. But what?

Nietzsche's Philosophy of Action

This is the penultimate draft of an essay for The Blackwell Companion to the Philosophy of Action being edited by Timothy O'Connor and Constantine Sandis, that should be out in 2010. I am still working on the issues here (and have worked on them previously, as some readers will recognize), and welcome comments--especially since there were significant space constraints in this piece, which will be less of a factor in the work-in-progress on these themes.
