Quine asserts, 'As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience.
Physical objects (tables chairs) are conceptually imported into our situation as convenient intermediaries not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer, claims the redoubtable Quine.
In Quine's view For my part I do believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemology (what we deem to be knowledge) of the physical objects and the Gods differ only in degree and not in kind.
Both sorts of entities enter our conceptions only as cultural posits. Let us then call this
'Ontological relativity'. Hmmm!
