I think we might be on the same page at last. The last refuge of the Cartesian is always, "My argument is correct in an ineffable way that I couldn't possibly write down." "Cogito ergo sum" presents itself as a self-evident deduction, the one guaranteed universally agreeable truth, but, when you investigate it a little… oh, well, it's really more of a vibe than an argument, and isn't "logical argument" really a monkey-mind distraction from the indescribable lightness of existence? Mu, indeed.
