The mythopoetic nature of what was written before should be clear: Peano Arithmetic, read as individual-Reality genesis/Cogito. A crisper genesis has never been related.
But what was the point of what I just wrote? That the Cartesian subject, in extremis, is not a circularity of signification devoid of human intent, but is, in fact, the human intent within the purest, most circular signification ever: the very mathematics that grounds our reality. Mathematics is, after all, a tool, like any other. But one that gives birth to foundation, and to grounding, and to reality.
