Not all politics is of one kind. To be sure, all politics centers on the state, the most comprehensive order of human existence. Practically as well as theoretically, however, one must distinguish between (1) the politics of justice, and (2) the politics of existence. In some political science departments these two are called “government” and “international relations.” Nor are these the only kinds of politics. One can further distinguish (3) the politics of foundation and (4) the politics of revolution, both of which, however, can be set aside in the present context.
