Agreed. However, I think it's important to begin with the big picture:
- Platonism and its offspring subscribe to a worldview that includes things beyond what is natural. These things include "Forms" and "Ideals" which are more real than material reality.
- Epicurus rejected anything beyond the natural, including "Forms" and "Ideals" which are more real than material reality.
That may be enough for some people to know, without diving deeper into the details. But every discussion of the details which has been prompted by a Platonist argument needs to begin with the explicit understanding that Platonism is antithetical to EP for these reasons. And this needs to be repeated, early and often. Apples and oranges.
How do you describe Platonism in Epicurean terms? You can't: it's nonsense. How do you describe EP in Platonic terms? The best example that we have comes from Epicurus, but in today's world that is extremely difficult to decipher. So every argument needs to begin with this distinction, because the Platonists insist on arguing in their own terms and discard the Epicurean worldview. If we want to resuscitate EP, we need to argue in our own terms. In this way we can point out the absurdities of Platonism while we explain EP.
That's my rant I'm not trying to refute any of the arguments being made above, I just feel that they need to be firmly and repeatedly placed in the proper context. Reframed. Which is to see Platonism through Epicurean eyes, and not to see EP through Platonic eyes. They're fundamentally incompatible.
