Are you agreeing or disagreeing with the idea that we can't know anything for certain, but within a certain set of assumptions and given a certain probability within those assumptions we can say we know some things?
Well this isn't really what I've been going after, but to answer your question (as best I can) - I have no problem with what are usually referred to as 'basal assumptions' - ie the universe exists and we can learn things about it etc etc. As for 100% 'absolute' certainty with zero possibility of being wrong, no, I don't believe that. But I don't really want to go here because it might turn into that semantics argument over what knowledge really is. Back to my toe stubbing (sick of hearing about my toe yet?!) example. I'm happy to say I KNOW it happened. But seeing as I can't show it to any degree at all, and mindful of Aron's catchphrase, should I be claiming I know this?
