In one important respect, Frege's approach to ontological commitment is in agreement with Quine's. Both hold that the smallest unit of ontological commitment is the complete sentence.  For Frege, this can be seen as an uncontroversial application of his famous Context Principle: “it is only in the context of a proposition that words have any meaning” (Frege 1884: §62). It follows that attribution of ontological commitment to persons always goes by way of the theories (sentences) that they accept. This approach to ontological commitment is common to all mainstream views in contemporary analytic philosophy. It could be denied, however, by a philosopher who holds that we stand in intentional relations, not only to propositions, but also to objects. For such a philosopher, plausibly, a person is ontologically committed to the objects of her thought, and the kinds they exemplify, independently of what propositions she takes to be true of those objects, or even whether there are any such propositions.
