Too cheap to buy books, so I'm reading the excerpts Amazon and Google Booksearch give me for free. I never thought I'd say this, but not having the right books does limit one. I can safely say I'm dumber for not having read certain things.

@beccah - I was thinking the exact same thing. And it's free. hah

The trouble with the public library is they don't quite carry this book:

http://www.amazon.com/Argument-Action-Essays-Poetry-Philosophy/dp/0226042510/ref=wl_it_dp?ie=UTF8&coliid=IX8UQEVZGRW9B&colid=17HGKINB62AA1

Excerpt from the book: "The knowledge of cause, however, does not establish first philosophy; it merely discloses what still must be known, being. Being emerges as the problem of first philosophy through the nonproblematic status of the four causes. The emergence of being as a problem is not adventitious to the four causes." (I'm not reading that essay, by the way, but the one later in the book on the Phaedo.)

I'll definitely look into the book exchange, there's gotta be an academic out there who's tired of seeing the same thing sit on his bookshelf collecting dust.

@AA: Thanks! I actually hadn't even heard of bookfinder before.
