To bolster his consequence argument against David Lewis's rejoinder, Peter van Inwagen uses the concept of miracle. He claims that the Lewisian compatibilist must admit that under determinism, we possess the ability to work miracles par excellence, that is, not just in some purely technical sense of the term. The article argues that van Inwagen's definition of a ‘miracle’ is too broad even if it is interpreted merely as an explication of one component often thought to be inherent in the religious concept of miracle, namely the concept of an event that breaks the laws of nature. Nomological effects of miracles are not miracles themselves.
