Abstract

Realism in logic asserts that logical theories should reflect an autonomous reality independent of the mind, language, inferential practices, and any other human conventions. Traditionally, logical reality has been conceived as a Platonic realm of abstract entities, but more recent versions suggest that natural reality itself somehow contains the elements that make logical laws true. This article provides a brief critical introduction to logical realism and highlights how the realist conception is prevalent in the current debate in the philosophy of logic, particularly within the anti-exceptionalism stream on logic. The main challenge of realism lies in the indeterminacy of the nature of logical reality and, consequently, the set of data that logical theories should take into account. As an alternative to logical realism, we present logical conventionalism, which assumes that logical laws do not correspond to any reality but are instead conventions established by logicians. However, conventionalism also faces its own set of problems. The article concludes by acknowledging the difficulties surrounding the metaphysics of logic.
