As we continue to discuss some of these issues I want to restate what I think are ultimate issues in Epicurean physics from which no retreat makes sense:
The first issue is whether matter is INFINITELY divisible. Epicurus says no in part because of the logical contradictions that would be involved in accepting it. It matters not whether we are talking what we today consider to be "atoms" or "subatomic particles" or "quarks" or whatever term is applied from here to the end of humanity. Logically, at SOME point the divisibility must stop.
Another issue is whether matter is acted on by some OUTSIDE FORCE (other than that which (1) we consider to have real material existence and (2) empty space) to give it organization. That is the issue we are discussing in terms of "weight vs gravity' or other terminology. The question is whether matter requires some OUTSIDE force (not matter and not space, which are the two divisions of all things) to bring about its organization. Epicurus again says no. To accept such an outside force is to open the door to any sort of "divinity" or 'supernatural" that any mystic wants to suggest. It matters not whether what we are referring to as matter or material is hard bodies, energy, fields, or whatever, so long as it is repeatedly detectable and/or "measurable" by the senses and its technological amplifications
As I see it currently this pretty much sets the terms of the "nature of the universe" debate. Anyone here see that differently or able to state it better?
