Journal of the History of Ideas 59.3 (1998) 463-484 The Virtues of Animals in Seventeenth-Century Thought Peter Harrison Discussions about animals--their purpose, their minds or souls, their interior operations, our duties towards them--have always played a role in human self-understanding. At no time, however, except perhaps our own, have such concerns sparked the magnitude of debate which took place during the course of the seventeenth century. The agenda had been set in the late 1500s by Montaigne, who had made the remarkable (if somewhat rhetorical) claim that animals were both moral and rational, and moreover, more moral and rational than humans. In the century which followed, Descartes, not to be outdone, put forward the even more contentious counter-proposal that animals were not only neither rational nor moral, but that they were not even conscious. The Cartesian hypothesis fueled a debate which continued until well into the eighteenth century. 1 While in recent years much attention has been given to issues of animal consciousness and cognition in seventeenth-century thought, the related question of the moral capabilities of animals has been by comparison neglected. In this paper I shall explore the converse side of the better known arguments about the rational capabilities of the beasts, focusing on seventeenth-century discussions concerning the behaviors and passions of the beasts and the extent to which animals were thought to participate in the moral universe of human beings. I. During the first sixteen hundred years of the common era, those thinkers who directed their attention to the natural world had tended to be preoccupied neither with questions of how animals came into being nor with the direct [End Page 463] causes of their various operations but rather with the question of why they existed at all. Almost without exception responses to this question were variations on a single theme: animals had been placed in the world to provide for the physical needs of human beings. 2 While this response proved to be satisfactory in general terms, there were acknowledged deficiencies. Many living things seemed to have been rather extravagantly designed for their putative purpose. Others seemed blatantly to contradict it. Why were our meat supplies, for example, not more conveniently presented, like the fabled Scythian lamb which grew on a tree? Why was it that a significant number of creatures appeared to be useless or even downright harmful to those whom they were designed to serve? And why, finally, were human beings created such that they were dependent upon lesser creatures for their survival?
