Despite Glouberman—s paper, I adhere to the terms I used earlier to describe the contest between Descartes and Gassendi (and their followers—which was the major part of my argument, unexamined by Glouberman). His attribution to me of a positivist conception of philosophical activity, I claim, better characterizes his own attitude toward evidence, truth, and the cognitive significance of metaphysical claims. Part of what was at stake between Descartes and Gassendi was a communal model of knowledge; within this context, I raise (...) questions about standards of scholarship and their significance.

Descartes understood the subject matter of physics (or natural philosophy) to encompass the whole of nature, including living things. It therefore comprised not only nonvital phenomena, including those we would now denominate as physical, chemical, minerological, magnetic, and atmospheric; it also extended to the world of plants and animals, including the human animal (with the exception of those aspects of the human mind that Descartes assigned to solely to thinking substance: pure intellect and will). Descartes wrote extensively on physiology and (...) on the physiology and psychology of the senses. This chapter examines the notions of *physiology* and *psychology* in medical and natural philosophical works of Descartes' day; follows his efforts to bring physiology into his mechanistic idiom; considers the relation between physiology of the animal machine and psychological functions that yield functionally appropriate behavior; goes into his physiology and psychology of vision; and elaborates the tension in Descartes' works between his metaphysically supported micro-corpuscularism and his discussion of the animal machine as an organic unity comprising various functionally and teleologically characterized systems. The chapter draws on Descartes' works in both metaphysics and natural philosophy, including his Treatise on Man (originally published as L'Homme, 1664). (shrink)
