Professor Kateb and I seem to be caught up in a game of chicken, each trying to outdo the other in his disdain for patriotism. As an Australian, all I can say is, I think Australians are better anti-patriots than Americans.
The more serious question, however, is what comes first: patriotism or the (warring) state? The egg or the chicken? In evolutionary biology, the chicken comes from the egg, which came from an earlier kind of chicken: the two evolved together. In political theory, the conclusion surely must be that patriotism and the state also evolved together, their being, if not impossible without one another, at least mutually reinforcing. George Kateb is worried about the patriot egg; I think he should be at least as worried about the chicken.
Like Professor Kateb, I am not an enthusiast for the group. But some groups are more troubling than others and need to be diminished. The state is such a group and I reserve my sternest criticisms for it. I dare Professor Kateb to join me.
