No. My argument is that there are people who walk around with a fairly complete SENSE of propositional logic and a SENSE of a system and a SENSE of a system of propositional logic. I never said that I or any single individual could recreate the PRODUCT of countless centuries of contemplation by thousands of other individuals with that SENSE, in one lifetime.

No. I saw a truth table and said (to myself) "Of course!".

I suppose you think music is also like this. Mostly just hard work?

The biggest point in my previous post wasn't that the senses that people have in these things varies greatly (which is obvious). It was that in order to have ignition, the sense must be moderately high. Otherwise, the fire goes out as soon as you remove the match.
