Descartes is well known as a mathematician and natural philosopher. However, none of Descartes's biographers has described the invitation he received in 1633 to fill a chair in theoretical medicine at the University of Bologna, or the fact that he was already sufficiently known and respected for his medical knowledge that the invitation came four years before his first publication. In this note I authenticate and contextualize this event, which I refer to as the ‘Bologna affair’. I transcribe the letter (...) written to the Bolognese Senate announcing efforts to bring Descartes to the university and explain the events that led to Descartes receiving the invitation. While many questions about the Bologna affair cannot be answered because of the paucity of the historical record, I conclude that the event invites us to consider again the larger historiographical issue of how best to integrate the history of medicine with the history of science and philosophy during the early modern period.

ArgumentTalk of “reason” and “rationality” has been perennial in the philosophy and sciences of the European, Latin tradition since antiquity. But the use of these terms in the early-modern period has left especial marks on the specialties and disciplines that emerged as components of “science” in the modern world. By examining discussions by seventeenth-century philosophers, including natural philosophers such as Descartes, Pascal, and Hobbes, the practical meanings of, specifically, inferential reasoning can be seen as reducing, for most, to intellectual processes (...) deriving from foundations that required intuitional insight that was owing to God. Mechanical reasoning, or artificial intelligence, was a contradiction in terms for such as Pascal, whose views of his own arithmetical machine illustrate the issue well. Hobbes’ analysis of reason, however, replaced the ineffable authority of God with the authority of the civil power, to reveal the social reality of “reason” as nothing other than authorized judgment.
