It’s exasperating. Continentals are secular theologians at best. But even analytic philosophers are mostly sophists. Try to explain that the logics are falsificationary not justificationary. Ask them to try to prove something non trivial. Heads explode.
Better, try “The liar’s paradox isn’t, it’s just a sophism of grammar using the copula in an incomplete sentence.” In fact, ask them to state any difficult philosophical question without using the verb to be, in a complete sentence, in operational language. Oops. Sophisms all.
Very frustrating for philosophers playing cunning word games to realize that (a) almost all supposedly complex questions are merely errors in grammar, and (b) there is no closure available to the logics, (c) the logics are purely falsificationary – just like the sciences.
