  In 1646, as a result of the probings of Princess Elisabeth, Descartes completed a working draft of Passions de l’ame (Passions of the Soul). During this year another prominent political figure began to correspond with Descartes, Queen Christina of Sweden. And, Regius published what he took to be a new and improved version of Cartesian science, which as we now know would draw the wrath of Voetius. But Regius did not stop there, for he seemed to have found important differences between his “Cartesian” view and that of Descartes’, and attempted to separate the two, publishing a broadsheet that listed twenty-one anti-Cartesian theses (which his version of “Cartesian” science rejected). In response to this, Descartes wrote a single-page printed defense that was posted on public kiosks for all to read. Published in 1648, the Notae in Programma Quoddam (Notes on a Program-also referred to as Comments on a Certain Broadsheet) is Descartes’ public defense. However, as mentioned earlier, tensions mounted as a result of the public exchange and Descartes felt his way of life in the Netherlands to be threatened. As luck would have it, an admirer and friend of Descartes’—Chanut, who worked for Queen Christina’s court—and Queen Christina herself began probing Descartes about the possibility of coming to Sweden. And, after a not too lengthy correspondence, Queen Christina offered Descartes a position in her court. For many reasons, which would certanily include those related to his concerns about Voetius, Descartes accepted the offer. And, in 1649 he left for Sweden.
