Infinite Regressions, etc.

The diagram to the right is a little model I'm working through right now, in trying to categorize and simplify the universe. I have decided to set up this model, on something of a whim, so it will need refinement. Even now, looking at it, I see some flaws in my labeling. Regardless, I think this model can be a valuable asset for such categorization.
The model tries to explain the goals of philosophy. The two major goals are the explanation of the universe, and the critique of society. Philosophy is a system acting within the universe, trying to improve the world around it by explanation, systemazation, and critique. Meta(beyond)philosophy seeks to improve philosophy.
Examples of normal philosophy includes Kierkegaard's discussions of the Danish church and people. His critiques of Hegelian methodology are meta-philosophical, seeking to improve philosophy. The teaching of logic is meta-philosophical. "The Ethics of Belief" (Clifford) are double-meta-philosophical (in some ways), trying to improve the improvement of philosophy. Post-modernism tries to question philosophy and methodology.
Philosophy as a whole appears on every level of this spectrum-- the diagram can be drawn all the way down, if it is necessary. The improvement of society requires the improvement of philosophy, and that requires the improvement of meta-philosophy, etc. Although the idea seems rather ridiculous, and to me, hard to get a good handle on, it is necessary to realize that the ultimate goal of philosophy is this: to improve society and understand the universe.
