A major issue in political philosophy is the extent to which one or another version of nationalism or, by contrast, cosmopolitanism, is morally justified. Nationalism, like cosmopolitanism, may be understood as a position on the status and responsibilities of nation states, but the terms may also be used to designate attitudes appropriate to those positions. One problem in political philosophy is to distinguish and appraise various forms of nationalism and cosmopolitanism ; a related problem is how to understand the relation (...) of patriotism to each. Nationalists may tend to be patriots, but need not be; patriots may tend to be nationalists, but need not be. Like nationalism, patriotism may also be considered in propositional forms or in related attitudinal forms; but unlike nationalism and cosmopolitanism, patriotism can exist in the form of an emotion: roughly, love of one’s country. This paper characterizes nationalism, cosmopolitanism, and patriotism in both forms and argues for a conception of patriotism on which it is both distinct from nationalism and compatible with certain kinds of cosmopolitanism. It also suggests that, in qualified forms, nationalism and cosmopolitanism may overlap in what they require of their proponents. (shrink)
