This is my attempt to make sense of Nietzsche's idea that it is only as an aesthetic phenomenon that existence is "justified."   This is the final version, except perhaps for some minor style editing, and will appear in Journal of Nietzsche Studies this fall.  This version is citable.  It will still also appear in  volume of essays that Nietzsche Daniel Came (Lincoln) is editing, but it will be out this fall in JNS.
