Abstract

This paper explains the motivation behind Aristotle’s appeal in Nicomachean Ethics 1154b7–9 to the physiologoi, who notoriously declare that animals are constantly in pain. It argues that the physiologoi are neither the critical target of this chapter nor invoked to verify Aristotle’s commitment to the imperfection of the human condition. Rather, despite doctrinal disagreement, they help Aristotle develop a naturalistic story about how ordinary people easily indulge in sensory pleasures.
