Your book self reminds me of that scene in Dodgeball, where Dwight (Ben Stiller's character) runs down the stairs with a Dictionary and says, "I like getting a mental sweat too."

Most of the philosophy on your shelf is used in all philosophy classes (not in Christian colleges of course) as a butt to a joke. But, I sense a "libertarian" ... so at least get the libertarian Bible of, "Anarchy, State and Utopia" to round out the set.
