According to W. V. Quine, science advocates a physicalist ontology and an empiricist epistemology. However, Quine’s ontological physicalism includes the abstract objects of mathematics, such as numbers or sets. So, Quine’s commitments to empiricism are firm but not permanent. Quine has incorporated various elements of pragmatic thought into his philosophical outlook, that is why I advocate that Quine’s philosophy decidedly gives to the pragmatic view of empiricism.
