Tanner Leighton

I am a philosopher working in the pragmatist tradition on the philosophy and ethics of artificial intelligence, with a secondary focus on the foundations of quantum theory. I received my PhD in History and Philosophy of Science from the University of Pittsburgh in February 2026, under the supervision of David Wallace. I am currently a Postdoctoral Research Associate in the Department of Philosophy at Texas A&M University.

My research develops irenic pragmatism—a methodologically conservative framework in the Rorty-Brandom-Price neo-pragmatist tradition—and applies it to foundational questions in the philosophy of technology and science. Using this approach, I diagnose entrenched disputes in the philosophy of AI, philosophy of language, and quantum foundations by separating shared practice-level commitments from further semantic or metaphysical overlays, and defend the adequacy of the resulting “core” pragmatist view. I develop a positive account of linguistic agency in large language models, diagnose accountability gaps that arise when AI systems are deployed in practice, and articulate a practice-anchored core interpretation of quantum theory.

I also hold a B.S. in Physics and Philosophy from the University of Minnesota and have programming experience in Python, C++, and MATLAB.
