Agustín Rayo is a Mexican-born analytic philosopher at the Massachusetts Institute of Technology, specializing in philosophy of language, philosophy of mathematics, and philosophical logic. He is best known for developing 'trivialist platonism,' the view that mathematical truths are metaphysically trivial and require no special ontological grounding. His work systematically investigates the limits of quantification, the structure of logical space, and the semantics of 'just is' statements.
