Isn't self-predication part of the problem? It's the answer to this anon's question:
Why does the form of something, like large, have that property? If you're retarded, you might say "well the form of large is large because it has largeness". In which case the man partakes in largeness, and the form of large also partakes in largeness, so now there is a largeness that is over the man and the form. But why is that third thing large? I guess it participates in largeness too, lmao.
I don't know why you would say that the form of large has "large" as a predicate (self-predication) rather than it per se being the large and being present wherever largeness is present, but I'm not familiar with all the hand wringing about models of "participation" and forms.
To go back to the first anon, yes, I think we have to be strict about viewing reality a cohesive, unified whole (Being). Reality is one unchanging, perfect thing and whatever details or information there is, it is of Being. Not some strange model of independent things that partake in other independent things and can change into "what is not" in accordance with this system and as powered by the magic of negation/beyond-Being.
