Abstract

Descartes (1596-1650) is generally regarded as the first of the modern philosophers. Indeed, until about 50 years ago most philosophers would have said that Descartes was the first significant philosopher since Aristotle. Descartes himself does not draw attention to his sources--not to conceal them (that would have been pointless, because to his contemporaries the continuities of his thought with the books they had all been brought up on would have been obvious), but so as to avoid getting embroiled in learned disputes about who had said what and what they had meant. Descartes wanted his readers to look at his arguments and judge them by using their own intelligence. He calls on his readers to empty their minds of prejudices, i.e. previous judgments, and take a fresh look. His writings had such an impact that philosophy after Descartes generally took his arguments and positions as a starting point or as a point of reference, and earlier writers were no longer read. (There was a social reason for this also: philosophical books were, after Descartes set the example, generally addressed in French or some other vernacular language to lay readers outside the universities, and most readers could not easily read the Latin authors Descartes had himself read when he was a student of the Jesuits.) So it came to be thought that Descartes had had no significant predecessors--that all of his ideas were original. Descartes was indeed an original thinker, but he used a good deal of medieval material. In this lecture I want to go through Descartes' chief work in philosophy, The Meditations , outlining the argument and drawing attention to the medieval material.
