[A thought experiment and your bookshelf.]

The Bible - Here is something on which a basic morality and spirituality can be established. Without this, all else is for naught.

The Libertarian Reader - David Boaz, (an assortment of philosophy, from Locke to Jefferson to Mill - it covers the basic principles needed to form a government).

The Articles of Confederation and the Constitution - They usually come together, more principles on which to build a society.

Democracy in America - Tocqueville (offers knowledge of how a productive society and a virtuous one can prosper).

Why Be Good? - Richter (a collection of philosophy from the likes of Kant and Humes, also necessary to develop morality).

I like this guy.
