Yale Weiss is the Assistant Director of the Saul Kripke Center at the Graduate Center of the City University of New York. He received his PhD from the Graduate Center in 2019. He has published widely on logic (including on conditional, connexive, intuitionistic, modal, and relevance logic) and its history (with a focus on ancient logic). Romina Birman (née Padró) is the Director of the Saul Kripke Center at the Graduate Center of the City University of New York. She received her PhD from the Graduate Center in 2015, with a dissertation entitled, “What the Tortoise Said to Kripke: The Adoption Problem and the Epistemology of Logic”. Her research focuses on the epistemology of logic and the philosophy of language. She collaborated with Saul Kripke on numerous projects, including Philosophical Troubles.
