Abstract
Mr. Cohen's political geography is unexpectedly topical. His conception of political philosophy is not so advanced; however Cohen's disposition is all for forward movement. Insisting perhaps too strongly upon the etymology of "political," Cohen would even have us cease doing "political philosophy"; for, he says, there are no longer any truly sovereign and autonomous states left in the world. The era of the nation-state has vanished quite as definitely into the past as the era of the city-state. We live in a "polycentric" world community, under a regime of law, though the world community is not itself a sovereign state, nor are there any sovereign states that are a part of it. The members of the world community are people, obliged to support whatever international laws and agencies of international collaboration there are, and there are many of them. To assert that there is a world community is to imply that there are no sovereign national states to impose obligations equally eminent or superior.
