Abstract
Aristotle's Politics claims that the polis or city-state "exists by nature" (Pol. 1.2.1252630). Thinkers as diverse as Marsilius of Padua, Thomas Hobbes, and Martha Nussbaum have struggled with how to interpret such a claim-some finding in it a salutary alternative to existing political theories, others finding in it the basis of deeply wrong-headed political thinking. In Aristotle on the Nature of Community, Adriel Trott seeks both to elucidate and to defend Aristotle's claim about the naturalness of the polis by interpreting nature in the Politics through the notion of nature as an internal principle of motion ( a notion central to the understanding of natural things articulated in his treatise thereupon, viz. Physics2.1).
