I came to similar conclusions.....unimpressed.
Sad truth.....intellect is not enough.
Just as necessary is courage - the psychological constitution to accept what you eprcive.....to acknowledge and follow the patterns you perceive to their logical ends.
An impressive analysis would begin with the agency of philosophy - man himself, i.e., his psychology.
Then the medium of philosophy, i.e., semiotics, words/symbols.
Then the world and how the first two align with this third.....and finally one can venture into metaphysics, using the previous three to maintain balance and not to be derailed into romantic idealism, or mysticism and the superstitions of old women and effete men.
