To the extent you are saying that it seems likely to you that advanced beings would take interest in lesser beings as a matter of pleasure to themselves, I think Epicurus would also say "of course" and he would point to his position on isonomia and on infinite numbers of worlds with life on them and he would say of course there are highly advanced beings who do exactly like that, just like we do ourselves, but on a far more advanced scale that would seem to most of us as being "godlike." The isonomia view would I think allow for an infinite progression / spectrum of advancement above us.
I read about Isonomia in DeWitt and did not understand it, it seeming suspiciously platonic. I left it for later and haven't gotten to it. How important is this concept? Could you ellaborate on what it is and what is it useful for?
