Abstract
In this essay, I first outline the contexts in which the idea of cosmopolitanism appears in Kant's moral and political philosophy. I then survey the three main debates regarding his political cosmopolitanism, namely, on the nature of the international federation he advocated, his theory of cosmopolitan right, and his views on colonialism and ‘race’, and I consider the relation between patriotism and cosmopolitanism in Kant's work. I subsequently discuss Kant's moral cosmopolitanism. Kant is widely held to be a defender of moral cosmopolitanism, but the terminology of world citizenship is in fact strikingly rare in Kant's writings on moral theory. I offer a two-part explanation for why this is the case
