In many of his writings, Quine has argued that language is indeterminate in various ways. He has pursued, at length and often, an ingenious conclusion about one such way, which he sometimes calls the inscrutability of reference and, sometimes, the inscrutability of terms. It is the conclusion that one dimension of indeterminacy leaves the references of general terms unfixed among a number of alternatives; further, that no sort of scrutiny of the terms or of the occasions of their utterance could, in principle, provide a means for settling objectively which referent to assign to a term. This single doctrine assumes various guises: there is a firm claim about incompatible but equally acceptable translations of certain Japanese classifiers; there is a somewhat less clear commitment to the inscrutability of a choice between expressions and their Godel numbers as referents for quoted expressions; further, there is a yet more tentative endorsement of Harman's example of the various referents of numerical expressions given by competing set theoretic reductions of number.
