A Taxonomy of Philosophy

This is a preliminary and incomplete taxonomy of areas of philosophy, to be used in the PhilPapers project for accessing philosophical papers. See this post (and ensuing discussion) on Fragments of Consciousness for more details. Asterisks ("*") are attached to subcategories that are listed more than once, when they are listed under a nonprimary parent category paper.
