 A final question for pluralists is whether they are correct to take rival logicians to be arguing about the same logical principles. The classical logician accepts a logical truth which they write “A ∨¬A” and the Strong Kleene rejects as a logical truth a principle which they write the same way. But it only follows that they accept different logics if the symbols express the same principle in both cases, and in particular, if “∨” and “¬” mean the same in both.
