Help. A few days ago a professor stated that no philosophy is actually "complete," in the sense that it can prove everything down to its most basic premises. He then quoted Aristotle as support, citing that "you cannot prove the more known by the less known," or something close to that i likely got it wrong but im sure the geniuses here will get it. This professor is a physicist and a huge thomist. I have been fucked up by something similar to this for a while, that no philosophy ive read about is absolutely certain, and yet I cant even certainly prove to myself that I'll never figure that out. So even my uncertainty is uncertain. Id like to believe in God. Camus really tilted me by saying "yeah shits wack deal with it,". Has anyone, materialist, metaphysician, or whatever Schopenhauer believed in, offered a claim to total and comprehensive certainty? I'm literally going insane with this, and if I dont fix it soon I'm just going to give into Catholicism. I'm tired of the bemusement.
