This paper addresses John Burgess's answer to the ‘Benacerraf Problem’: How could we come justifiably to believe anything implying that there are numbers, given that it does not make sense to ascribe location or causal powers to numbers?

This paper investigates what lies behind Burgess's answer and ends up as a rebuttal to Burgess's reasoning
