 A fourth objection to sufficiency has to do with how the criterion relates to issues of realism and reduction, to the distinction between kinds of entity that are fundamental and kinds that are derived. It might seem that in cases of ontological reduction the quantifier criterion sometimes imputes ontological commitments where there should be none. Consider a view that identifies chairs with sums of particles, and takes only the particles, not their sums, to be fundamental. Consider the sentence ‘∃x Chair(x)’, and ask: is it ontologically committed to chairs? The answer, on the quantifier criterion, is “yes”: chairs must be among the values of the variable ‘x’ in order for the sentence to be true.[20] But, one might object, since chairs are not fundamental on the view in question, they should not be counted among the sentence's ontological commitments. One can hold that there are chairs without being ontologically committed to chairs.
