Currently I have been on a Pragmatism reading binge, trying to marry engineering and pragmatism. Surprisingly, I do not own any Roberto Mangabeira Unger (He is so bad ass, you must say his full name). I have been following some of his lectures and such, and this is pretty great.

The Self Awakened: Pragmatism Unbound |Roberto Mangabeira Unger

P.S. In case you do not know Pragmatism is the American Philosophy.
