Some years ago I picked up a copy of the On Being and Essence by St. Thomas Aquinas, tranlated and commented by Joseph Bobik. It cost me $8.95 (CAD) at the used book store, and it was entirely worth it. It took the metaphysics course I had at the seminary, which gave me the basics, and allowed me to penetrate even more deeply into the “Meaning of Being”. It also took me months to read, simply because it was so dense, but every morsel was a meal in itself.Aristotle, in the Metaphysics, wants to study Being in itself, for what it is.
