This is a marvelous book. Steven Landsburg attempted to answer some interesting questions* with ideas from mathematics, economics, and physics! If you have a chance, you should take a look at it--it should provide you with new perspectives on many things, even if you disagree with it.
*Questions like "Why is there something instead of nothing?", "Where does mathematical knowledge come from?", "How to tell Right from Wrong?", "How not to be a jerk?", etc.
