There is a wide spectrum of views on whether ordinary language quantification is ontologically committing. On one end of the spectrum is the view that all ordinary assertive uses of the quantifiers ‘there is’ and ‘some’ are ontologically committing, a view that may be dubbed “allism” (see Lewis 1990, and §1.6.4 above). On this view, discovering the ontological commitments of ordinary speakers is easy. In asserting that “some prime numbers are greater than 100”, we commit ourselves to the existence of numbers; in asserting that “there are properties that all great leaders have in common”, we commit ourselves to the existence of properties. Ontological commitment cannot be avoided by paraphrasing these sentences into the ontologically serious portion of our language because these ordinary assertions are already ontologically serious.[40]
