Philosophy attempts to develop a consisitent apprehension of the world. Philosophy seeks to integrate the knowledge of the sciences with that of other fields of study to achieve a consistent and coherent worldview (a weltanschauung).
Philosophy vs. “My Philosophy”: Philosophy requires self-consistency, self-reflection, and a degree of analysis. By contrast, a personal philosophy may well be merely a limiting ideology that one intends not to be challenged at all.
About Categories: Successful forums have few categories to start, so discussion is not spread out too thin. Eventually, after existing categories are well seasoned, pressure nudges a new one into existence as a wrapper for an already existing discussion.
