Beall is also widely known for advocating a glut-theoretic account of deflationary truth (Spandrels of Truth (2009) (glut theory is the view that there are true contradictions, a special case of which is dialetheism).

Against the standard no-gap tradition in glut theory, 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 glut-theoretic framework, who usually accept only gluts.
