In this essay, I examine the compatibility of Kantian cosmopolitanism and patriotism. In response to recent literature, I first argue that in order to discuss this issue fruitfully, one should distinguish between three different forms of patriotism and be careful to make clear when patriotism is obligatory, permissible, or prohibited. I then show that Kantians can defend the view that civic patriotism is a duty, but that attempts to also establish nationalist patriotism and trait-based patriotism as Kantian duties fail. Showing (...) that civic patriotism is a duty does not by itself show that it is compatible with cosmopolitanism, however, and I therefore examine the relationship between different duties in more detail, arguing that there is no conflict of duties here. Finally, I argue that Kantianism provides even a bit of room for nationalist and trait-based patriotism to count as having moral worth, although this room is very narrowly circumscribed. (shrink)
