Books to read

I am reading a fantastic book by Thomas Sowell called A Conflict of Visions. The book advances a theory about two opposing ways of looking at the world - the constrained and the unconstrained - and posits that each vision forms the basis of the differences in political ideologies that continue to this date. Sowell is so smart he will make your head hurt - but his use of practical applications and direct quotes from major contributors to the respective visions make this book a joy to read.
