Physical idealism

[Mudhammam]

I am a bit puzzled by your thinking that atheism and Platonism can peacefully coexist. At a minimum, Platonic objects are both supernatural and immaterial, which most atheists would reject. Holding to that sort of minimal Platonism would not, I suppose, require someone to believe an intelligent agent governs the Realm of Forms. At the same time, not doing so seems to stop short of a fully developed Platonism, like that of Plotinus, who to my mind is the epitome of pagan Platonist thought.

I'm not sure how you could derive the supernatural directly from Platonism unless you simply equate nature with the physical world, rather than allowing certain Platonic objects to equally constitute its form... though, obviously, none so extravagant as some deities are so defined. There's nothing intrinsic to the idea of immaterial beings (such as geometric figures) that must be excluded in one's rejection of entities represented by the admixture of attributes oftentimes annexed to the various gods. Plotinus, if I recall, also believed that neither existence nor non-existence, being nor non-being, could be predicated upon "the One" or the "All", as it was wholly incomprehensible. In other words, it was a meaningless proposition, in much the same way that I take the claim that the universe came from nothing to be a meaningless proposition.
