“Conventions need have no rationale apart from the rationale of having a convention.”

Jonathan Webber is a professor at Cardiff University specializing in moral philosophy and the philosophy of psychology. His work explores how contemporary social psychology can inform debates in moral philosophy and the intersection of philosophy and psychology with twentieth-century French existentialism.

He is President of the UK Sartre Society, a Trustee of The Mind Association, and served as President of the British Society for Ethical Theory from 2014-2019. His most recent book, Rethinking Existentialism, has been praised as "the only book one needs."

“Webber takes the reader on a journey of rethinking existentialism.” — Phenomenological Reviews
