So I've come across a wide range of philosophy majors a few years ago in my brief exploration of Philosophy classes, and I wasn't very impressed with their technical knowledge.  That is, not being able to understand upper level division texts on Metaphysics (a and b time, that Quine paper on Pegagsus, unable to use predicate logic in papers outside of the necessary logic course, etc.)  My exposure to Philosophy ended at 20 or so credits, and then work and fitness took over my spare time.    

Now I want to get back into the subject, but I'm not in the position to jump right into hard material.  So what recommended sequence of reading should I start with?

Anyone read Just the Arguments: 100 arguemtns in Philosophy?
