Tyler Cowen started a "which 10 books have influenced me most" blogging trend, and many people have followed. Though not nearly as accomplished as Mr Cowen, I'm going to do the same thing. I've already posted a reading list, found at http://tfideas.blogspot.com/2009/05/reading-list.html, but it's old and I've read a great deal beyond that since then (though many of the top choices haven't changed).
The final list:
1. Berkshire Hathaway Shareholder Letters, Warren Buffett. How I learned business theory.
2. Common Stocks, Uncommon Profits, Philip Arthur Fisher. How I learned investment research.
3. Influence, Robert Cialdini. How I learned about behavioral psychology.
4. Dialogues, Plato. How I learned logic and argument structure.
5. Democracy in America, De Tocqueville. How I learned about American government.
6. Utilitarianism, John Stuart Mill. How I learned the advantages and disadvantages of a "quantitative" philosophy.
7. The Elements of Style, Strunk and White. How I learned prose.
8. The Complete Works of Shakespeare, William Shakespeare. How I learned about evocative language.
9. The Alchemy of Finance, George Soros. How I learned about booms and busts, currency theory and making smart bets.
10. Les Miserables, Victor Hugo. How I evaluate the quality of writing, and gave a framework for religious morality without a necessary direct religion.
1. Influence, Robert Cialdini.

The Bible (the basis of Western morality)
The Prince/Discourses on Titus Livy (Niccolo Machiavelli) (political incentives)
Les Miserables (Victor Hugo) (made me appreciate good writing, because it's the most beautiful prose I've ever read)
Competitive Strategy (Michael Porter) (Industrial Organization and economics)
Critique of Pure Reason (Immanuel Kant) (Argumentation)
The Federalist Papers (Hamilton/Madison/Jay) (American vision).
I don't include an intro Statistics or Economics text because I don't have one in particular that is epic beyond words, but if I did, I'd include it (Mankiw's not bad, but that's not how I learned economics). I'm tempted to include Michael Pettis' blog and JK Rowling's Harvard Commencement speech but I'll keep it to books.
I suppose that Competitive Strategy is somewhat duplicated by Buffett, and Critique of Pure Reason is somewhat duplicated by Plato and any sort of internal negative response to Mill, and the Federalist Papers is somewhat duplicated by de Tocqueville.
