I took a look through my copy of Dewitt and he goes on and on about the Twelve Elementary Principles... But with what authority? He just states, with no citation to an actual text, things like:
The procedure was regularly from the general to the particular. The truths of Physics were reduced to Twelve Elementary Principles. These
corresponded to a general map, affording a panoramic view of the nature of things. Of the Twelve Principles the most important was the third:" The universe consists of atoms and void."
How can he state this so matter-of-factly? What is her basing this statement on? How does he know this is the third principle? Did I miss Lucretius expounding the Δώδεκα στοιχειώσεσί? I've tried to get just twelve principles from the letter to Herodotus and it's not easily done. Without question, Epicurus wrote a work called Δώδεκα στοιχειώσεσί but Diogenes doesn't list it among the most important works of the philosopher. Is it a later compilation? And are we sure it's about physics as I asked in my previous post. I respect Dewitt's scholarship (mostly), but many times he flies off in flights of fancy with, from what I can see, little to back it up.
