I appreciate your response.
I understand you will probably reject this, because of the overwhemingly nominalist cast of modern culture and philosophy. But that's OK, and thanks for reading.
I think we are currently in different headspaces: you view this as a dispute between nominalism and realism, whereas I see it as a semantic note. For me, ‘reality’ is the ‘totality of what exists’; and ‘existence’ is the primitive concept of ‘being’. What I understand you to be doing, is trying to convey an interesting point with (in my opinion) bad semantics by making a distinction between existing
qua the universe (or what is phenomenal) vs.
qua the form of that universe. The problem with this is the same as
@Mww: you are positing that something can
not exist but
is, when, in truth, what you are really trying to convey is that something can exist
which is not a part of the physical universe. It is impossible, still yet, for me to coherently parse your semantics since you confirm the
existence of things which
do not exist (according to your schema)—e.g., the square root.
I was not, and am not, suggesting that nominalism is necessarily true: I wasn’t intending to comment on that whatsoever, and still don’t feel the need to given my complaint above. However, if I must, then I would say that the rationality which we perceive as the form of the universe, to me, is the transcendental ideality of human
a priori cognition. To me, I struggle with providing any proofs about reality as it is in-itself. To me, to take a ‘realist’ account, in the medieval sense, is to necessarily posit that the
a priori ways by which we experience is a 1:1 mirror of the forms of the universe itself; and I have absolutely no clue why I should believe that. Likewise, to posit a nominalist account, I don’t see any reason to believe that, given the modern perspective, we understand that reality in-itself lacks any forms. Perhaps you can give some insight into this.
Things that exist as phenomena. And recall, 'phenomena' means 'what appears'.
Perhaps I am too stuck in the Kantian mindset; but the Peirceian perspective you quoted was, by my lights, about reality in-itself—not phenomena.
