An inquiry into the nature and causes of the wealth of nations by Adam Smith. After that I have The Politics by Aristotle lined up anyone else read this?
Sir, you are a hero. I am a philosophy major (as well as history), are you as well?
But anyway, if you find the empiricist movement to be of interst, I would recommend reading Francis Hutcheson and David Hume, they being the core of the Scottish Enlightenment along with Adam Smith. Hume's Treatise and Enquiry are his foundational works, but any of his essays, such as Of Commerce, are quite intersting as well. With Hutcheson, I would recommend An Essay on the Nature and Conduct of the Passions and Affections as well as An Inquiry into the Original of Our Ideas of Beauty and Virtue. Also, Smith's Lectures on Jurisprudence are of interest.
If you want to get them on the cheap, as well as some very well done editions, go to www.libertyfund.org They specialize in selling Natural Law and Enlightenment texts for non-profit, so most books are insanely cheap.
Sadly, Hume's Treatise and Enquiry are best done in the Oxford editions, which are rather expensive. Very well done, however.

Anyway, always good to meet a fellow philosopher.
