Abstract
Although the concept of miracle rarely appears in Derrida's philosophy, it is possible to define it, obviously very differently from its traditional theological meaning. In Derrida's philosophy, the miracle becomes the very structure of belief, involved in any address to others. Miracle is thus regarded as a ‘bare faith’, that is, as the irreducibility of the religious. As a result, it is no longer defined as something that departs from naturalistic probability: on the contrary, the structure of ‘the miraculous’ is one of the names of the ethics of the impossible, in the form of an aporetic structure of the event.
