Neglected sources on Cartesianism: the academic dictata of Johannes de Raey

In this article, I provide a historical and bibliographical exploration of the handwritten, dictated commentaries (dictata) of Johannes de Raey (1620/1622-1702) on the texts of Ren & eacute; Descartes (1596-1650), shedding light on their structure, development, and on their relations with the academic commentaries of Johannes Clauberg (1622-1665) and Christoph Wittich (1625-1687). The study of these commentaries, which are extant as class notes, is important because they conveyed one of the first systematic teachings of Descartes's ideas and constituted a vehicle for their further dissemination across northern Europe.
