Sorta... I like the Theory of Nothing. It is a neutral monism that I can
buy, but I assume that Becoming is "fundamental": change exists at all
levels - this can happen when we reject a global timing scheme! The neat
thing is that a change is not a "thing", at best it is a transition between
a pair of things...
