Abstract

Aristotle of Stagira (384–322 BCE) originates the study of zoology and political science. But whereas his zoology identifies a continuum between human and non-human animals, in his political and ethical works he appears to view human and non-human animals as different in kind in order to illustrate the superiority of the former and justify the instrumental use of the latter. For instance, Aristotle’s account of the virtue of moderation (namely that which concerns how humans experience pleasure) depicts non-human animals as predators who only view other animals as a meal and immoderate human animals as beast-like and disgraceful because they act, “not insofar as they are human beings but insofar as they are animals” (EN 3.10.1118b2–3). Nonetheless, Aristotle wrote another ethical treatise, the Eudemian Ethics, that offers discussions that parallel those in the Nicomachean Ethics but that eschew negative characterizations of non-human animals—as if Aristotle had excised all such negative depictions of non-human animals from the Eudemian text on rhetorical grounds. I argue that the reason that Aristotle treats pleasure so differently is the result of his contrast between ethics as a function of political science (as found in the Nicomachean Ethics) and a “non-political” ethical reflection (as found in the Eudemian Ethics) that is more in line with Aristotle the zoologist.
