Thomas Browne was born in London on the 19th of October 1605, the son of a silk merchant. Little is known of his childhood, and the accounts of his life following completion of his master's degree at Oxford tell us scarcely anything about the nature of his later medical studies. All we know for certain is that from his twenty-fifth to his twenty-eighth year he attended the universities of Montpellier, Padua and Vienna, then outstanding in the Hippocratic sciences, and that just before returning to England, received a doctorate in medicine from Leiden. In January 1632, while Browne was in Holland, and thus at a time when he was engaging more profoundly with the mysteries of the human body than ever before, the dissection of a corpse was undertaken in public at the Waaggebouw in Amsterdam — the body being that of Adriaan Adriaanszoon alias Aris Kindt, a petty thief of that city who had been hanged for his misdemeanours an hour or so earlier. Although we have no definite evidence for this, it is probable that Browne would have heard of the dissection and was present at the extraordinary event, which Rembrandt depicted in his painting of the Guild of Surgeons, for the anatomy lessons given every year in the depth of winter by Dr Nicolaas Tulp were not only of the greatest interest to a student of medicine but constituted in addition a significant date in the agenda of a society that saw itself as emerging from the darkness into the light. The spectacle, presented before a paying public drawn from the upper classes, was no doubt a demonstration of the undaunted investigative zeal in the new sciences; but it also represented (though this surely would have been refuted) the archaic ritual of dismembering a corpse, of harrowing the flesh of the delinquent even beyond death, a procedure then still part of the ordained punishment. That the anatomy lesson in Amsterdam was about more than a thorough knowledge of the inner organs of the human body is suggested by Rembrandt's representation of the ceremonial nature of the dissection — the surgeons are in their finest attire, and Dr Tulp is wearing a hat on his head — as well as by the fact that afterwards there was a formal, and in a sense symbolic banquet. If we stand today before the large canvas of Rembrandt's The Anatomy Lesson in the Mauritshuis we are standing precisely where those who were present at the dissection in the Waaggebouw stood, and we believe that we see what they saw then: in the foreground, the greenish, prone body of Aris Kindt, his neck broken and his chest risen terribly in rigor mortis. And yet it is debatable whether anyone ever really saw that body, since the art of anatomy, then in its infancy, was not least a way of making the reprobate body invisible. It is somehow odd that Dr Tulp's colleagues are not looking at Kindt's body, that their gaze is directed just past it to focus on the open anatomical atlas in which the appalling physical facts are reduced to a diagram, a schematic plan of the human being, such as envisaged by the enthusiastic amateur anatomist René Descartes, who was also, so it is said, present that January morning in the Waaggebouw. In his philosophical investigations, which form one of the principal chapters of the history of subjection, Descartes teaches that one should disregard the flesh, which is beyond our comprehension, and attend to the machine within, to what can fully be understood, be made wholly useful for work, and, in the event of any fault, either repaired or discarded.
