Confirmation Theory and Indispensability.

In this paper I examine Quine‘s indispensability argument, with particular emphasis on what is meant by ’indispensable‘. I show that confirmation theory plays a crucial role in answering this question and that once indispensability is understood in this light, Quine‘s argument is seen to be a serious stumbling block for any scientific realist wishing to maintain an anti-realist position with regard to mathematical entities.
