Rene Descartes: Secret Jesuit Agent

According to the account given in his notebook - no copy of which exists, but which has been reconstructed using contemporary reports - Descartes formulated his philosophy of methodical doubt after a day in a stove-heated room and an ensuing night of extraordinary dreams. Grayling points out that the dreams were remarkably similar to those described in Rosicrucian texts. It is known that Descartes had many acquaintances among the Rosicrucians. Can we be sure that the intrepid rationalist was not a secret intellectual ally of these hermetic thinkers? Grayling thinks it unlikely, and makes the intriguing suggestion that Descartes may have been a spy working in the service of the Jesuits, who formed contacts with the Rosicrucians as part of an intelligence-gathering operation. In the nature of the case, there can be no proof, but it leaves the philosopher looking a surprisingly adventurous figure.
