Differences between Logics and Meaning-Variance:A Categorial Approach

We argue here that the meanings of logical connectives need not differ in different logics. treatment of the logical connectives, we argue against the well-known Quinean thesis that a difference between logics implies a difference in the meanings of connectives. We thus locate this change in the difference between certain objects rather than in the difference between the meaning of connectives. Finally, we by to show that the category-theoretic treatment of logical connectives is a form of semantic minimalism, according to which not all the usual semantic components are relevant in fixing the meaning of a connective.</p
