Frazer MacBride’s Notes on W.V.O. Quine "On What There Is" (MPhil Stud Seminar, Birkbeck, 3rd October 2005)
Fundamental Point: "To be assumed as an entity is, purely and simply, to be reckoned as the value of a variable.... We are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true" (OWI: 13).
Structure of paper
There's no necessity to admit non-existent objects because
show that being meaningful and naming are different things.
(TD5): The F Gs ↔ (∃xFx & (∀yFy → x=y)) & Gx
There is no need to admit mysterious entities like being red any more than non-existent things like Pegasus because
Clarifying ontological commitment by comparison with philosophy of mathematics:
realism—logicism, conceptualism—intuitionism, nominalism—formalism.
A criterion of ontological commitment does not tell us what there is, but what someone says there is; whether we accept what someone says is guided by the general ideals of theory construction; a choice of ontology is determined by the over-all conceptual scheme that accommodates science in the broadest sense.
