"The core idea of common-sense realism," writes Curry, "is that there are self-evident truths -- truths which do not need to be proved." These truths "are the foundation of human understanding; they are the necessary basis for knowing anything at all" (emphasis mine).
Because these truths are so foundational, various parallel universes -- universes of pure ideology -- come into being with their denial. I mean this literally, because the universe includes its own fulfillment in the human subject, a la Whitehead. In other words, the human person is not incidental to the whole cosmic Hebang, but absolutely central.
Indeed, person is the ultimate category, both the source and summit of reality. Being and truth are essentially two sides of the same coin, which is precisely why knowledge of truth is possible. And if it is possible it is necessary -- for the same reason that if it is possible to avoid evil, it is necessary to do so. (In other words, our truth-knowing capacity entails an intrinsic moral demand, i.e., to know it and to not lie about it.)
Eh, probably didn't explain that too well. Let's just move on. Or better, maybe you've noticed those puzzling quotes by Voegelin and Schuon in the comment box. Both go to the point I'm trying to make:
The quest, thus, has no external 'object,' but is reality itself becoming luminous for its movement from the ineffable, through the Cosmos, to the ineffable (Voegelin); and Fundamentally there are only three miracles: existence, life, intelligence; with intelligence, the curve springing from God closes on itself like a ring that in reality has never been parted from the Infinite (Schuon).
Like a joke, you'll either get those or you won't. Each describes the ultimate movement of existence, and our participation in that movement. And since it happens, there must be a principle that explains how it is possible for it to happen. That principle is the Meta-cosmic Person.
In fact, when it fails to happen -- when there is a break in the circle from ineffable being to personal truth -- that's when one of those parallel universes branches into being. No, literally. By definition there is only one uni-verse, so all others are counterfeits.
Now, the universe is the totality and unicity of all objects (exteriorities), events (processes), and experiences (interiorities). Thus, to say, for example, that there are objects but no subjects (or that subjects are epiphenomenal) is to sever the cosmos at the root and veer into a parallel universe that can't even account for the absurd subject who posits and inhabits it.
Am I just digging a deeper hole? If so, I'll bet Dávila can help dig us out of it. Read them slowly so as to partake of their verticality, such that they launch you upward:
--The truth is objective but not impersonal.
--The life of the intelligence is a dialogue between the personalism of spirit and the impersonalism of reason.
--Truth is a person.
--The permanent possibility of initiating causal series is what we call a person.
--The universe is important if it is appearance, and insignificant if it is reality.
--The world is explicable from man; but man is not explicable from the world. Man is a given reality; the world is a hypothesis we invent.
--The free act is only conceivable in a created universe. In the universe that results from a free act. God exists for me in the same act in which I exist.
--The universe is a useless dictionary for someone who does not provide its proper syntax.
In each of these, we see the centrality of personhood, and how personhood is bound up with the reality behind appearances. It's just common sense!
