"This is the real problem. Philosophers can’t prove their own existence to themselves, how can they be expected to prove anything else?"
Whereas the rest of us are easily able to prove to our full satisfaction that atoms didn't exist, asbestos was safe, white flour no different than brown... etc, etc. It's not just possible for there to be too much certainty in the world, it's common - which is what that Billionaire knew thanks to courses in Philosophy, and exploited to earn his stash 'o cash.
Incidentally Buddhists think that any proof of individuality is false or tainted, too. Best lump them in there too. (Descartes had to please the church, we can't know his private opinion, just his published works with necessary nods to the church.)
The guy who in the end just said "Fuck it, a Wizard (God) did it."? It's really interesting to see the logical hole he digs for himself in the book but then cops out in the end with a "Well, God is good so he wouldn't let something bad happen to us so we must exist."
https://en.m.wikipedia.org/wiki/Trademark_argument. You kind of have it backwards, he first concluded that he existed (I think therefore I am). Then because of that (and other arguments), he believed god exists and is good, so he wouldn’t deceive his senses.
He basically defined existence as thinking, then turned it into a tautology. And then it blew up in his face when he realized that he couldn't prove anything else was thinking. And in fact even if there wasn't some devil tricking him (ala brain in a box hooked to the Matrix), things like rocks and water could never exist.
His entire philosophy was flawed right from the start. But it usually is. That's why so many philosophy texts take the first chapter (or volume) refuting philosophers who came before them.
Not really. That was just Socrates being Socrates and being all humble about his knowledge. Apart from him I don't remember any othe philosopher adopting that stance.
