The recent scholarly promotion of Pierre Gassendi to a key position in the formative modern period raises doubts about the portrayal of Descartes as “the father” of the post-Scholastic philosophical conceptualization. I defend the Cartesio-centric account against Thomas M. Lennon’s elliptical alternative. The defense necessitates a reassessment of the root nature of Descartes’s contribution—specifically of the interplay between philosophy and science, the latter being the crucial extraphilosophical component of the new practico-cognitive ensemble. This raises questions about the “philosophically” of Descartes’s (...) activity, and with that questions about the quality of modernity. By way of explaining Gassendis nonoriginative position, his attitude toward the post-Scholastic Humanist thought that Descartes simply repudiated is examined. (shrink)
