Although the basis of modern biology is Cartesian, Descartes’s theories of biology have been more often ridiculed than studied. Yet, Dennis Des Chene demonstrates, the themes, arguments, and vocabulary of his mechanistic biology pervade the writings of many seventeenth-century authors. In his illuminating account of Cartesian physiology in its historical context, Des Chene focuses on the philosopher’s innovative reworking of that field, including the nature of life, the problem of generation, and the concepts of health and illness. Des Chene begins (...) by surveying works that Descartes would likely have encountered, from late Aristotelian theories of the soul to medical literature and treatises on machines. The Cartesian theory of vital operations is examined, with particular attention to the generation of animals. Des Chene also considers the role of the machine-model in furnishing a method in physiology, the ambiguities of the notion of machine, and of Descartes’s problem of simulation. Finally, he looks at,the various kinds of unity of the body, both in itself and in its union with the soul. Spirits and Clocks continues Des Chene’s highly regarded exploration -- begun in his previous book, Life’s Form -- of the scholastic and Cartesian sciences as well as the dialogue between these two worldviews.

Descartes is often accused of having fragmented the human being into two independent substances, mind and body, with no clear strategy for explaining the apparent unity of human experience. Deborah Brown argues that, contrary to this view, Descartes did in fact have a conception of a single, integrated human being, and that in his view this conception is crucial to the success of human beings as rational and moral agents and as practitioners of science. The passions are pivotal in this, (...) and in a rich and wide-ranging discussion she examines Descartes' place in the tradition of thought about the passions, the metaphysics of actions and passions, sensory representation, and Descartes' account of self-mastery and virtue. Her study is an important and original reading not only of Descartes' account of mind-body unity but also of his theory of mind. (shrink)
