Abstract

Descartes’ distinction between infinite and indefinite is important for his philosophy, but poorly understood. Various commentators have offered conflicting interpretations of it; some have even questioned ist importance. In this paper I wish to investigate Descartes’ various discussions of the distinction and to use my investigation to shed light on the related question of the authority of the "Conversation with Burman". I believe that the distinction is treated differently in the "Conversation" than it is in the Cartesian corpus proper and that the difference of treatment is paradigmatic of other differences between that work and the works which come from Descartes’ own hand. I divide my discussion into two parts: first, on the reliability of the "Conversation" and Ferdinand Alquié’s critique of it; and second, on the distinction between the infinite and indefinite.
