Connective Meanings in Beall and Restall's Logical Pluralism

Teresa Kouri (Ohio State) gives a talk at the MCMP Colloquium (21 May, 2015) titled "Connective Meanings in Beall and Restall's Logical Pluralism". Abstract: I will show that there is a problem with the meanings of the connectives as presented in Beall and Restall's Logical Pluralism. In their system, they claim that $\neg$ in constructive logic and $\neg$ in relevant logic are one and the same. I show this cannot be, given how they have defined the meaning of a logical connective. I suggest that this type of problem is typical of a certain way of thinking about the meanings of connectives, and gesture towards an alternate route to logical pluralism which does not encounter such problems.
