Abstract
This paper begins from the observation that in the Meditations, Descartes never achieves the 'pure', thoroughly decontextualized kind of thinking he famously promoted. Some commentators have used this observation to promote pure inquiry more diligently and to criticize Descartes for failing to achieve it. Other commentators have simply called for greater historical fairness and urged that we renew our efforts to understand how Descartes's inquiry actually does operate. This paper, although sympathetic with this second group of commentators, argues that in revisiting the tensions between what Descartes actually accomplished and what he said he was trying to accomplish, we should see a contemporary lesson, not just better historical understanding. It is argued that in spite of the strong presence in his writings of the imagery of the 'Cartesian' ideal of a perfectly presuppositionless philosophical standpoint, not only does Descartes himself never become a Cartesian, but his own practice provides perhaps the best evidence against the very possibility of the Cartesian 'project of pure inquiry' to which he aspired.
