All of these anecdotes, and there are many more culled from all manner of sources, make this potentially heavy-going book entertaining reading. However Sawday's main business lies with unravelling his themes from a number of Renaissance figures (both major and minor) ranging from Spenser and Donne to Descartes and Rembrandt. Particularly interesting is his argument that the specific concerns of Cartesian dualism--that fragmentation of the self not only into a soul and a body, but also of the mind into a self that can observe itself thinking--were already 'in the air' before Descartes came to formulate his own position. Was this already an evolving Weltanschauung in the period which began to achieve hegemony only after Descartes became the first to offer a systematic account with the publication of his Discourse on the Method in 1637 and Meditations on First Philosophy in 1641 (146-7)? This is an interesting question and asking it allows Sawday to produce a technically anachronistic but convincing 'Cartesian' reading of Rembrandt's famous painting The Anatomy Lesson of Dr Nicolaes Tulp (1632). Sawday places Descartes in Amsterdam (by then becoming one of the major centres for anatomy in Northern Europe) during the early 1630s at exactly the same time as Rembrandt, and allows the ghost of a possible meeting between the two deliciously to haunt his description of the centrepiece of Rembrandt's painting:
- . . . Tulp's forceps are delicately probing the flexor digitorum muscles of Adreaenszoon's [the name of the cadaver, an executed coat-thief] left hand. By pulling on these flexor muscles, the (dead) fingers are made to curl, a gesture which Tulp echoes with his own (living) left hand. . . . One intellect (Tulp's) has animated two bodies, one of which is living, and the other is dead. In the dead body, the will--voluntas--has been extinguished, but the mechanism--'the laws of mechanics' which, Descartes was to explain . . . inhabit all of nature--was still in operation. In the extinction of Adreaenszoon's will, lay the triumph of Tulp's intellect. (153)
Descartes was then in the middle of his own anatomical investigations, studying the works of Vesalius, probably attending dissections in the anatomy theatre, and scouring the butchers' stalls purchasing carcasses for his own dissection (148). It is entirely possible that the Cartesian notion of the body as a machine animated by the soul was inspired by the 'culture of dissection' itself. This opens up interesting perspectives on the origins of the modern European world outlook and is just one of the many delights of Sawday's rich, dense but highly rewarding book.
