Cesare Cozzo studied at Rome, Florence and Stockholm. He is Professor of Logic at the Department of Philosophy of the University of Rome "La Sapienza". His main research has been in theory of meaning and philosophy of logic. He is author of three books: Teoria del significato e filosofia della logica (Clueb, Bologna 1994), Meaning and Argument (Almqvist & Wiksell, Stockholm 1994), Introduzione a Dummett (Laterza, Roma 2008), and of several articles. A significant part of his work has been focused on the idea that the sense of a linguistic expression is given by some rules for its use in arguments: he has developed a fallibilist and non-holistic version of this idea.
