Abstract
In his paper ‘Wang’s Paradox’, Michael Dummett provides an argument
for why strict finitism in mathematics is internally inconsistent and therefore an untenable position. Dummett’s argument proceeds by making two
claims: (1) Strict finitism is committed to the claim that there are sets of natural numbers which are closed under the successor operation but
nonetheless have an upper bound; (2) Such a commitment is inconsistent,
even by finitistic standards.
In this paper I claim that Dummett’s argument fails. I question both
parts of Dummett’s argument, but most importantly I claim that Dummett’s
argument in favour of the second claim crucially relies on an implicit
assumption that Dummett does not acknowledge and that the strict
finitist need not accept.
