Will to Nothingness, Naturalism, Super-Naturalism

Nietzsche's thesis that "man would rather will nothing than not will", presented in the Genealogy of Morals, is significant in two main respects.  First, as has been previously discussed, the thesis expresses a Will to Die, and, so, poses a counter-example to the standard Will to Live.  Second, it reinforces Nietzsche's Naturalism.  For, one of the traditionally accepted strengths of Super-Naturalism is its thesis that Naturalism can be derived from it, but not conversely, a proposition that is at the heart of various 'Cosmological' arguments.  However, as he explains in the Genealogy, a Will to Nothingness can be the source of concepts of  an 'after-world', which is tantamount to demonstrating that a Super-Natural realm can be derived from a Naturalistic principle.
