The Philosophy of Penelope Maddy

Juliette Kennedy has been a member of the Department of Mathematics and Statistics at the University of Helsinki since 1999. Her work in mathematical logic is focused mainly in the areas of set-theoretic model theory and set theory, but she has also worked in models of arithmetic. In the history, philosophy and foundations of mathematics and logic she has worked extensively on Gödel; but she has also written on Turing, Tarski and Kreisel. In her recent work she has focused on the syntax/semantics distinction; she also works avocationally in the art field as a curator.

Sophia Arbeiter is a graduate student in the Department of Philosophy at the University of Pittsburgh. Previously, she has studied Philosophy and Logic at the University of Vienna and Paris Panthéon-Sorbonne. Her current work is focused on the philosophy of logic, such as logical pluralism and the normativity of logic, as well as the History of Analytic Philosophy, most prominently Carnap.
