Work

Beall is best known in philosophy for contributions to philosophical logic and to the philosophy of logic. Beall, together with Greg Restall, is a pioneer of a widely discussed version of logical pluralism, according to which any given natural language has not one but many relations of logical consequence. Beall is also widely known for advocating a glut-theoretic account of deflationary truth.
Against the standard no-gap tradition in glut theory, also known as dialetheism, Beall's early and post-2013 work advocates a gluts-and-gaps account of language, advocating not only the existence of truth-value gluts but also of truth-value gaps. The adoption of both gaps and gluts distinguishes Beall from other researchers in a broadly dialetheist framework, who usually accept only gluts.
