Jc Beall is an American philosopher working in philosophy of logic and philosophical logic, who since 2020, holds the O’Neill Family Chair of Philosophy at the University of Notre Dame.

[2] He was previously the Board of Trustees Distinguished Professor of Philosophy at the University of Connecticut.

[3][4][5] Beall earned a BA in Philosophy from Grove City College.

Beall, together with Greg Restall (an Australian logician and philosopher), is a pioneer of a widely discussed version of logical pluralism,[7] according to which any given natural language has not one but many relations of logical consequence.

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.
