 Aristotle thinks that, in addition to friendships, wider social relations are required for the full development of our rational powers. He says in Nicomachean Ethics I.7 that we are by nature political beings, whose capacities are fully realized in a specific kind of political community (a polis or city-state). Aristotle’s ideal political community is led by citizens who recognize the value of living fully active lives and whose aim is to make the best life possible for their fellow citizens, thereby promoting the common good (Politics 1278b19–26, cf. 1280b8–12). When citizens deliberate and legislate about the community’s educational, office-holding, and economic policies, their goal is to determine and promote the conditions under which citizens can fully develop their deliberative and decision-making powers (Politics 1332b12–41).
