Funny comic strip! The comic author parodies the sense of purity among the various fields of study. This got me thinking -- when we think about life we probably start off with the sociological and pyschological aspects of it (relationships, personality, behavior, family, society), then try and explain it with biology and chemistry (all bodily/life functions are chemical (re)actions, my teacher once said). This leads to a discussion on physical matter and the universe -- the physics of it. We then try and reason it with mathematics, and when all fails, we abstract it with the notion of God.
I recently watched the movie Dasavatharam (btw, highly recommended movie) and there was this one quote I really liked. At the end of the movie, the protagonist (Kamal Hassan) says: "It's not that I don't believe God exists, all I am saying is...it will be good if he did (exist)".
