THe only record of Hiernymous of Rhodes is what Cicero says about him as explained in our earlier thread (note from 2019) with the citations. Hieronymus of Rhodes embraced "absence of pain" but not pleasure, as Cicero explains.
They support the point that when you have reached the "limit" of anything you still have the full volume of what you started with to build to that point. You do not have something different than water when you fill a glass of water to the brim. You have a glass of water, and to say that you at that point do not need water is to say that you need no MORE water, not that the water you have has become worthless because you filled the glass.
I realize that it is counterintuitive to have to say that when you complete the accumulation of something all you care about is the concept of the accumulation and not the content of it, but that is what the argument is about. It's simply not going to be something that can be understood without reading the argument that Plato made about "being" as the good, rather than "the becoming." At present the best guide through all of that is the first several chapters of Arenson's book, where she lays out all the citations to The Republic and to Philebus.
