I don't see how logic could not be our rational basis; rational discourse is destroyed without logic. — Lionino
What logic? Symbolic logic? Propositional logic? Dialectical logic? You are speaking of logic as if it were an objective reality, instead of a construct. — Pantagruel
Even acquiescing that logic is a construct, there are laws of logic (and related) without which we cannot productively have discourse. Law of identity, non-contradiction, law of excluded middle, the possibility of analytic judgements, etc. It is perfectly fine that a construct is fundamental. Scientific discourse relies on non-contradiction, as does any discourse. — Lionino
The law of non-contradiction doesn't apply to dialectical logic in any non-trivial sense, since dialectics assumes that opposing viewpoints can reach a synthesis. More generally, the "rules" exist in order to facilitate social interactions, which are themselves the bases of the meanings of our existence. So the laws of reasonable discourse are in aid of reasonable social interactions, not the determinants of them. — Pantagruel
Whether there is a society around me or not, I can reason — Lionino
Saying ‘Z ^ Znot’ is metaphysically impossible shifts the focus to a different proposition, X, which would have to be evaluated relative to a specified metaphysical theory, N. — Bob Ross
