I just finished reading
Metaphysics, by Aristotle...sort of.
A friend of mine is moving, and is divesting herself of several things that she's decided aren't worth keeping. This includes a set of thirteen
Classics Club books that her great-grandmother purchased when they originally came out in the 1940s. I was extremely touched to receive such a gift (she knows I'm a bibliophile), and immediately dug into them, making an arbitrary decision to begin with
Metaphysics from the volume entitled
On Man in the Universe, which collects several works by Aristotle.
The thing is, the selections themselves are apparently truncated versions of the full works. Or at least,
Metaphysics is, which is somewhat disappointing. Of course, that might be for the best, since this one was not an easy read by any stretch of the imagination. Having finished what parts were there, I have the distinct impression that I need to go back and read it again in order to develop a better appreciation.
On a tangential note, there's a brief reference to
Empedocles in there, a pre-Socratic philosopher whose work is still known today, as he's the one who proposed that matter was composed of air, earth, fire, and water. Less well known is that he also theorized that there were two forces which acted upon those elements; the one that mixed them he termed "Love," and the one that divided them was given the moniker "Strife."
It's almost like he came up with the idea that the Positive and Negative Energy Planes are also part of the Inner Planes!
