Does science justify any part of mathematics and, if so, what part? These questions are related to the so-called indispensability arguments propounded, among others, by Quine and Putnam. The general idea of the arguments has been fonnulated (for critical assessment) by Penelope Maddy in a recent article as follows:
We have good reason to believe our best scientific theories, and mathematical entities are indispensable to those theories, so we have good reason to believe in mathematical entities. Mathematics is thus on an ontological par with natural science. Furthermore, the evidence that continns scientific theories also confirms the required mathematics, so mathematics and science are on an epistemological par as weil. (Maddy 1992, p. 78)
