Here. I am grateful to those who commented on it last year at this blog. This will appear in The Oxford Handbook of Nietzsche (edited by Ken Gemes and John Richardson), due out later this year. There may be a few stylistic or citation tweaks, but this version is final as to substance, and is available for citation and quotation.
Additional comments are, of course, welcome, since these are topics and issues I'm still working on.
