Abstract

As is reasonably well-appreciated, Quine struggled with his definition of the all-important notion of an observation sentence; especially in order to make them bear out his commitment to language’s being a ‘social art’. In an earlier article (Mind 131(523):805–825, 2022), I proposed a certain repair, which here I will explain, justify and articulate further. But it also infects the definition of observation categoricals, and furthermore makes it a secondary matter, a seeming afterthought, that evidence, science and knowledge generally are shared—are joint, social and collaborative products. Without forsaking Quine’s strict naturalism, I try to make the necessary adjustments to Quine’s scheme.
