Logic and Pragmatics: linear logic for inferential practice Daniele Porello

Abstract. In this paper I disuss logic in the pragmatic apporach of (Brandom, 2008). I
consider differnt logical consequence relations (classical, intuitionistic and linear) and I will
argue that the formal treatment proposed by Brandom, even if I believe it provides powerful
intuions and an interesting framework on logic in general, doesn't allow to state properly the
relationship between differnt logics. I propose an alternative account of the elaboration of
logical vocabuilaries not based on incompatibility semantics, rather on a particular notion of
interaction, which I claim is implicit in the practice of giving and asking for reasons, which
allows to state the relationship between differnt logics in terms of differnt aspects of the
inferential practice.
