It may be argued that deflationary nominalists are changing the rules of the debate. They state that mathematicians derive statements of the form “There are Fs”, but insist that the objects in question do not exist, given that quantifier commitment and ontological commitment should be distinguished. This strategy is fundamentally different from those found in the nominalist proposals discussed before. It amounts to the denial of the first premise of the indispensability argument (“We ought to be ontologically committed to all and only those entities that are indispensable to our best theories of the world”). Even though quantification over mathematical entities is indispensable to our best theories of the world (thus, the deflationary nominalist accepts the second premise of the argument), this fact does not entail that these entities exist. After all, we can quantify over objects that do not exist, given the rejection of the indispensability argument's first premise.
