  What is Quine’s justification for relying on the idea of regimented theory, rather than on our ordinary conceptual scheme? (Cf. Strawson, 1959, Introduction.) One part of the answer is that just as science is in the same line of business as ordinary knowledge, but does it better, so regimented language is in the same business as ordinary language, but does it better. Regimentation, that is to say, is not the imposition of a wholly foreign language; it is the adoption of a language that maximizes scientific virtues already partially present in ordinary speech—logical structure, reference, the ready amenability to algorithmic methods. But another part of the answer is the idea that “our ordinary conceptual scheme” does not pick out anything definite enough to answer metaphysical questions. Thus Quine says: “…a fenced ontology is just not implicit in ordinary language…. Ontological concern is not a correction of a lay thought and practice; it is foreign to the lay culture, though an outgrowth of it.” (1981, 9).
