Wanting to learn Philosophy

     I'm looking for an eBook that covers the basics of philosophy. Not something on one specific subject, that basics for those who want to learn. Google isn't offering much help for this problem.

If you really want to learn about the basics of philosophy, I suggest <i>The Blackwell Guide to Philosophical Logic</i>.
This book is not light reading, so be prepared to actually learn something. 

How do you markup text on these boards? I didn't find a faq for the textboards.
