Descartes Reinvented. Cambridge-New York: Cambridge University Press, 2005. Pp. xxii + 204. Cloth, $75.00. The "reinvented" Descartes of the title denotes the spontaneous Cartesianism of those who, knowingly or not, presuppose or adopt positions resembling those of the historical Descartes. The historical Descartes accepted many propositions Sorell thinks we must reject; what remains, he calls "innocent Cartesianism." It is to the defense of innocent Cartesianism that Sorell's work is largely devoted. The task of the book is twofold: to recover from imputed..

In Descartes’s reformulation of natural philosophy, two aspects of what came to be known as the mechanical philosophy were intimately joined: mechanism as an ontology of nature, according to which all natural things had only ‘mechanical’ properties; and mechanism as a method of explanation. One could, and many philosophers did, adopt mechanism as a method of explanation without adopting a mechanistic ontology. I examine two successors of Descartes who did just that, and one who did not. Giovanni Alfonso Borelli in his De motu animalium and Charles Perrault in his Mécanique de animaux propose and argue for a variety of mechanical accounts of the operations of animals, in particular of their muscles. They reject, however, the Cartesian reduction of animal souls to mechanical forces; the principle of animal motion for them remains a non-mechanical soul. Pierre Sylvain Régis in his Cours entier de philosophie follows Descartes in taking the ‘physical cause’ of motion in animals to be the fermentation of blood in the heart, and thus denies animal souls any role in his physiology. That he can do so while taking over, sometimes word for word, Perrault’s accounts of animal motion shows that mechanistic explanation and mechanistic ontology could easily part company.

In recent years more and more scholars of early modern philosophy have come to acknowledge that our understanding of Descartes’s thought benefits greatly from consideration of his intellectual background. Research in this direction has taken off, but much work remains to be done. Dennis Des Chene offers a major contribution to this enterprise. This erudite book is the result of a very impressive body of research into a number of late Aristotelian scholastics, some fairly well known, such as Suárez, others quite obscure. Two thirds of the book is devoted to the Aristotelians, with occasional references to Descartes; the last third focuses on Descartes, although there still much Aristotelian ground is covered. Des Chene indicates three major themes for his book: natural change and agency, the structure of material substance, and finality.
