It’s odd that you won’t explain your epistemology to someone, but you will claim moral/intellectual superiority in not explaining an actually important point after debating them on the hypothetical sentience of the sun for over a day. You can throw all the names of theorems you want at a conversation. but the simple fact is that “there is no absolute truth” is a self-contradictory statement. Any philosophy you build on such a fragile foundation is a non-starter.
