L’homme is known as the first text-book of physiology, and the first purely mechanistic account of bodily functions. Descartes was one of the first to embrace Harvey’s doctrine of the circulation and the book opens with an account of the cardiovascular system, illustrated by a plate of the heart with movable flaps. From a mechanistic survey of general physiology, Descartes moves to the nervous system which he treats in great detail. Particularly important is his discussion of the eye (drawing on Kepler for the optical part) and the physiology of perception.
‘The impact of the Cartesian physiological program, once it was publicly known, was enormous. In two ways – philosophically and physiologically – Descartes transformed long-standing beliefs about animals and men. Philosophically, of course, his notions of mind-body dualism and animal automatism had extremely important implications that were not lost on Henry More, Malebranche, Spinoza, and Leibniz, along with many others in the seventeenth century ... But physiologically, too, Descartes’ conceptions had an impact that in many ways was even more impressive than the philosophical influence, because it affected the actual course of contemporary science’. (Theodore M. Brown in DSB)
The remarkable engravings and woodcuts were commissioned by Schuyl, Descartes having left only one or two sketches. The errata on the last page, headed ‘Nota’ mostly relate to the illustrations, and include a woodcut to replace Fig. xxv on p. 61 (the image is reversed and the lettering altered). When Clerselier edited the text for the French edition two years later (see next item) he rejected these illustrations and commissioned new ones.
