A Pretabular Classical Relevance Logic


In this paper we construct an extension, \({\mathcal{L}}\) , of Anderson and Belnap’s relevance logic R that is classical in the sense that it contains \({p \& \neg p \rightarrow q}\) as a theorem, and we prove that \({\mathcal{L}}\) is pretabular in the sense that while it does not have a finite characteristic matrix, every proper normal extension of it does. We end the paper by commenting on the possibility of finding other classical relevance logics that are also pretabular.
