If a person says, "The only thing that I know is that I know nothing." What exactly does that mean (not metaphorically), literally?
If the only thing they know is that they know nothing, then they know 1 thing. (in which case: nothing ≠ 1.)
But looks like they are saying they don't know anything at all. So, they know exactly 0 things.
If they knew nothing, then they obviously wouldn't have known that they know the fact that they do not know anything at all.
Is this a self-contradicting statement, which meaning is the logical one? It looks like the statement is true AND false at the same time. I have never taken any philosophy classes so forgive my ineptness but I thought I'd ask. I tried to find and read similar questions but it's a bit too technical for me and I couldn't say if it's the same concept or not.
