Abstract
This paper consists of two parts. In the first part, I shall expound the kantian concept of paradox and its three different senses, the anthropological, the rhetorical and the metaphysical. In the second part, I shall examine the presence of these senses of paradox in Kant’s texts about Enlightenment. The paradox of immaturity consists of the fact that we are responsible, as human beings, and non-responsible, as subjects of a State, of the exit from it. Another formulation of the same paradox, but in dynamical and metaphysical terms, is that of heautocracy, the paradox of self-constraint, which implies that the subject is at the same time active and passive. Finally, the opposition between public and private use of reason also seems paradoxical, since private use seems to be a prejudiced use while public use seems to be free and reasonable as such
