In this paper I outline a role for mechanistic conceptions of organisms in ancient Greek natural philosophy, especially the study of organisms. By ‘mechanistic conceptions’ I mean the use of ideas and techniques drawn from the field of mechanics to investigate the natural world. ‘Mechanistic conceptions’ of organisms in ancient Greek philosophy, then, are those that draw on the ancient understanding of the field called ‘mechanics’ — hê mêchanikê technê—to investigate living things, rather than those bearing some perceived similarity to (...) modern notions of ‘the mechanical.’ I have argued elsewhere that evidence of mechanistic conceptions of the natural world can be found, not only among seventeenth and eighteenth century ‘mechanical philosophers,’ but also—albeit in vestigial form — in some ancient Greek texts. Unfortunately, these reports are slight, often by detractors of this approach, and offer only clues as to the motivational context for employing these mechanical conceptions. Here, my purpose is to suggest what role they might have played in the history of natural philosophy. (shrink)

For Aristotle, animals, by contrast to plants, possess a perceptual soul. However, there is disagreement concerning the point at which the perceptual soul is acquired, for him. On one influential interpretation, Aristotle thinks that the perceptual soul is acquired not during the initial formation of the embryo, but at some later stage of its development. On such interpretations of Aristotle’s view, the newly formed embryo is not yet an actual animal, but a plant-like living being or even inanimate matter. We (...) argue, by contrast, that Aristotle views the embryo, from the very beginning, as an actual animal exercising basic nutritive and perceptual functions. We show that this interpretation is consistent with Aristotle’s views on embryogenesis in the GA, HA, PA, and the Metaphysics. (shrink)
