 (1) A famous Quinean motto has it that “to change the logic is to change the subject”: apparently disagreeing logical parties are actually speaking of different things. So when intuitionists deny that the Law of Excluded Middle holds in non-finitary contexts, they are actually changing the meaning of logical operators; when paraconsistentists claim that some formula can be true (in some weird circumstances) together with its negation, they are not talking of negation anymore (see e.g., Berto 2008).
