This paper addresses criticisms of the concept of untranslatability which Davidson and Putnam have raised against the incommensurability thesis.

Kripke and Putnam have proposed that terms may be introduced to refer to theoretical entities by means of causal descriptions such as 'whatever causes observable effects O'. It is argued that such a reference-fixing definition is ill-formed and that theoretical beliefs must be involved in fixing the reference of a theoretical term. Some examples of reference-fixing are discussed e.g., the term 'electricity'. The Kripke-Putnam theory can not give an account of how terms may be introduced into science and then subsequently (...) be discovered to be non-referring. A modified account of reference-fixing is suggested in which terms such as Gilbert's electric effluvia' and 'phlogiston' can be introduced into science and then be found to lack a reference.

It is argued that if Kuhn's current attempt to characterize conceptual incommensurability is correct, then the phenomenon of conceptual incommensurability is epistemologically innocuous. The first part of the paper explains why available techniques of reference specification provide rival scientists with sufficient access to one another's languages to compare their views. The second half of the paper attempts to elaborate an account of conceptual incommensurability that will develop (what the author takes to be) Kuhn's fundamental insight.

The author's concept of incommensurability is explicated by elaborating the claim that some terms essential to the formulation of older theories defy translation into the language of more recent ones. Defense of this claim rests on the distinction between interpreting a theory in a later language and translating the theory into it. The former is both possible and essential, the latter neither. The interpretation/translation distinction is then applied to Kitcher's critique of incommensurability and Quine's conception of a translation manual, both (...) of which take reference-preservation as the sole semantic criterion of translational adequacy. The paper concludes by enquiring about the additional criteria a successful translation must satisfy. (shrink)
