Abstract
Eugene Wigner’s 1960 article on the “unreasonable effectiveness of mathematics” used the word “miracle” of the fit between abstract mathematics and physical reality. William Lane Craig has developed a theistic argument from Wigner’s hints, claiming that the best explanation of the “miraculous” fit is divine creation. It is argued that this argument does not succeed. An Aristotelian realist philosophy of mathematics renders the applicability of mathematics to physical reality unmysterious by showing that mathematics, like any other science, is a study of certain aspects of reality, hence there is no miracle of fit. However, that does not preclude other arguments for the existence of God involving mathematics, for example design arguments from the elegance of the universe’s structure, fine-tuning arguments or ones from the nature of mathematical understanding.
