Beall and Restall’s Logical Pluralism and Minimal Monism about Logic

According to logical pluralism, there are several correct systems of logic. Most types of logical pluralism are based on the acceptance of logical relativism which means that the correctness of a system of logic depends entirely on distinct components of that system. Nevertheless, Beall and Restall claimed that they have proposed a kind of pluralism that is presented in a single language and does not entail accepting relativism. In this article, having introduced some of the most important types of logical pluralism, we tried to show that, contrary to Beall and Restall, their pluralism (i) cannot be presented in a single language; (ii) involves accepting a kind of relativism. Based on these results, we have tried to show that, by introducing a view titled “minimal monism”, if one wants to consider Beall and Restall pluralism as a credible perspective in this area, it is necessary for him to accept minimal monism.
