I was born in Montréal, where I was schooled at Collège Stanislas and where I obtained a B. A. (1982) and an M. A. (1984) in philosophy from the Université de Montréal, before going to New College, Oxford, obtaining the D.Phil. in 1992, with a thesis on Wittgenstein's philosophy of mathematics under the supervision of M. A. E. Dummett (with further supervision from Angus Macintyre in mathematics, and Crispin Wright at St. Andrews). I did afterwards post-doctoral studies at St. Andrews, Boston University (with Jaakko Hintikka), and back again at the Université de Montréal.

I taught at the University of Ottawa from 1994 until 2003, when I joined the Université du Québec à Montréal, as Canada Research Chair in the Philosophy of Logic and Mathematics (2003-2013). In addition, I have taught as invited professor at the Université de Paris I, Panthéon-Sorbonne, the Université Blaise-Pascal in Clermont-Ferrand, the University of Helsinki, the University of Latvia, Riga and Stockholm School of Economics in Riga, Keio University, Tokyo, at the Summer School on Wittgenstein’s Philosophy of Mathematics in 2018 at Kirchberg-am-Wechsel, Austria, and most recently at the University of Crete at Rethymno. I also hold the status of Visiting Fellow at Wolfson College, Oxford and the status of docent  the University of Helsinki.

I am full professor at  the Université du Québec à Montréal since 2009, where I was director of the Centre interuniversitaire de recherche sur la science et la technologie (CIRST) from 2015 to 2022. I am currently Director of the Department of Philosophy. I was elected Fellow of the Royal Society of Canada in 2016.

My main contributions are to the study of Wittgenstein's philosophy, especially his philosophy of mathematics. I have also contributed to the history of analytic philosophy and early 20th-century British philosophy (J. Cook Wilson & Oxford Realism, R. G. Collingwood, F. P. Ramsey, L. Rougier and F. Waismann). I have also published papers in philosophy of logic, which led to more recent publications on Ancient dialectic and the history of logic.
