@Ding an Sich,
Contradictory - there's no better word for a guy who says that he BOTH knows a lot and very little.
I am ready to admit that some posters cannot express themselves very clearly when dealing with metaphysics or epistemology, so I am giving him that space to rephrase and reflect on his (often poorly described) ideas, but he has not been willing to do so. E.g. I suggested that his "ultimate reality" could be the world of noumena described by Kant as inaccessible. He said no to that, dropping the word "ultimate" as useless, and I suspect that's because he didn't have a clue how to define it...
Now, perhaps because he knows he can't express himself very well, he is asking me to guess what his argument is... Figure that!
His "qualifier" is probably his "philosopher's bench" aka his "everyday life" proviso, that one cannot know anything in philosophy, but can know a lot in "every day life". Of course, philosophy is part of everyday life but that's beyond Frank. Frank approaches philosophy as I treat sudokus, as a frivolous pastime, not as something
relevant to his life.
