Emily Kress, "What Tools do you Need to Build an Animal? Heat and Coldness in Aristotle’s Generation of Animals"
Time & Location
About the Event
Aristotle analogizes the generation of an animal to what happens in craft production: just as a builder uses a saw and a hammer as “tools” to build a house, so too the soul uses “tools” to build an animal. I identify and attempt to resolve a puzzle about these tools: how can Aristotle hold both that what the tools do just is what soul does (GA 740b27-8), and also that the tools and the soul do different things (734b31-735a4)? My solution appeals to Aristotle's account of the role of capacities in efficient causation.
