Optimality And Teleology In Aristotle's Natural Science, Devin Henry Nov 2013

Optimality And Teleology In Aristotle's Natural Science, Devin Henry

Devin Henry

In this paper I examine the role of optimality reasoning in Aristotle’s natural science. By “optimality reasoning” I mean reasoning that appeals to some conception of “what is best” in order to explain why things are the way they are. We are first introduced to this pattern of reasoning in the famous passage at Phaedo 97b8-98a2, where (Plato’s) Socrates invokes “what is best” as a cause (aitia) of things in nature.

Aristotle’s answer to this question, I argue, is found in Generation of Animals Book 4 in connection with his investigation into the phenomenon of inheritance. There we are told that an organism’s reproductive material contains a set of ‘‘movements’’ which are derived from the various ‘‘potentials’’ of its nature (the internal principle of change that initiates and controls development). These ‘‘movements,’’ I suggest, function as specialized vehicles for com- municating the parts of the parent’s heritable form during …
