Sorry, you're going to have to dumb that down a bit for me here. I still don't really understand.
I'm going to swallow and pride and tell you that I often find you quite difficult to understand, fresco. I'm only sixteen; I don't know what "mutual semantics fields", "commonality" or "the law of the excluded middle" are, or who Wittgenstein and Piaget are. Please excuse me if this frustrates you, I understand.
I think I get the gist of what you are saying, though.
2. Although logic is only logical from our perception (this is what you are saying, right?), I think we only try to make sense of the world from our perception. Everything we know is from our perception. Indeed, I don't believe the "true" natures of the universe are knowable to us, for one because in order for an intelligent being to observe something, in must first be skewed and filtered to be observable. Everything must be viewed from some sort of incorrect or morphed perception.
3. Logic generally doesn't deal with sub-atomic particles; although nothing is certain (ignoring issues of certainty) on a quantum scale, things can be certain on our scale (correct me if I'm wrong).
