In Eastern philosophy the most contentious and celebrated topic is "the self" - what it is, how it is, when it is, etc. The branches of Western philosophy are: metaphysics (what is reality), cosmology (what is god), epistemology (how do we come to know things), aesthetics (what is beauty), ethics (what is right action). Other topics of philosophical debate include linguistics (semantics, syntax, learning, etc.) and socio-politics (the nature of "man"/ society), etc.
