In this paper I draw a connection between Kuhn and the empiricist legacy, specifically between his thesis of incommensurability, in particular in its later taxonomic form, and van Fraassen's constructive empiricism. I show that if it is the case the empirically equivalent but genuinely distinct theories do exist, then we can expect such theories to be taxonomically incommensurable. I link this to Hacking's claim that Kuhn was a nominalist. I also argue that Kuhn and van Fraassen do not differ as much as might be thought as regards the claim that observation is theory laden.

This article attempts to develop a rational reconstruction of Kuhn's epistemological relativism which effectively defends it against an influential line of criticism in the work of Shapere and Scheffler. Against the latter's reading of Kuhn, it is argued (1) that it is the incommensurability of scientific problems, data, and standards, not that of scientific meanings which primarily grounds the relativism argument; and (2) that Kuhnian incommensurability is compatible with far greater epistemological continuity from one theory to another than is implied by the criticisms in question. The reconstruction of Kuhn is then used to show that while it constitutes a provocative form of relativism, it can also plausibly account for the sense in which scientific development is rational, involves standards external to particular paradigms, and exhibits progress of a sort. Finally, the article attempts to develop an adequate critical perspective on Kuhn's relativism by distinguishing a ?short?run? from a ?long?run? relativism, and a relativism concerning scientific knowledge from one concerning scientific rationality in Kuhn; the challenge each poses to positi?vist philosophy of science is distinguished and separately evaluated.

The incommensurability thesis is the thesis that the content of some alternative scientific theories is incomparable due to translation failure between the vocabulary the theories employ. This paper presents an overview of the main issues which have arisen in the debate about incommensurability. It also briefly outlines a response to the thesis based on a modified causal theory of reference which allows change of reference subsequent to initial baptism, as well as a role to description in the determination of reference. On such a view. the content of theories may be compared on the basis of shared reference, despite failure of translation. Two recent developments involving the incomnensurability thesis are also examined: (i) the taxonomic version of the incomensurability thesis found in Kuhn’s later writings. (ii) Hoyningen-Huenc’s neo-Kantian interpretation of Kuhn’s metaphysics.

Central to Kuhn's notion of incommensurability are the ideas of meaning variance and lexicon, and the impossibility of translation of terms across different theories. Such a notion of incommensurability is based on a particular understanding of what a scientific language is. In this paper we first attempt to understand this notion of scientific language in the context of incommensurability. We consider the consequences of the essential multisemiotic character of scientific theories and show how this leads to even a single theory being potentially 'internally incommensurable'. We then discuss Kuhn's lexicon-based approach to incommensurability and the problems associated with it. Finally we argue that this approach by Kuhn has interesting overlaps with the problem of meaning associated with multisemiosis, particularly the challenge of understanding the process of symbolization in scientific theories.

Kuhn's ‘taxonomic conception’ of natural kinds enables him to defend and re-specify the notion of incommensurability against the idea that it is reference, not meaning/use, that is overwhelmingly important. Kuhn's ghost still lacks any reason to believe that referentialist essentialism undercuts his central arguments in SSR – and indeed, any reason to believe that such essentialism is even coherent, considered as a doctrine about anything remotely resembling our actual science. The actual relation of Kuhn to Kripke-Putnam essentialism, is as follows: Kuhn decisively undermines it – drawing upon the inadequacies of such essentialism when faced with the failure of attempts to instantiate in history or contemporaneously its ‘thought-experiment’ – and leaves the field open instead for his own more ‘realistic’, deflationary way of thinking about the operation of ‘natural kinds’ in science.

To correct the misconception that incommensurability implies incomparability, Kuhn lately develops a new interpretation of incommensurability. This includes a linguistic theory of scientific revolutions (the theory of kinds), a cognitive exploration of the language learning process (the analogy of bilingualism), and an epistemological discussion on the rationality of scientific development (the evolutionary epistemology). My focus in this paper is to review Kuhn's effort in eliminating relativism, highlighting both the insights and the difficulties of his new version of incommensurability . Finally I suggest that some of Kuhn's difficulties can be overcome by adopting a concept of rationality that filly appreciates the important role of instruments in the development of science.

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered within the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving (un)translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.

In a shift of position that has gone largely unnoticed by the great majority of commentators, Thomas Kuhn's version of the incommensurability thesis underwent a major transformation over the last decade and a half of his life. In his later work, Kuhn argued that incommensurability is a relation of translation failure between local subsets of interdefined theoretical terms, which encapsulate the taxonomic structure of a theory. Incommensurability arises because it is impossible to transfer the natural categories employed within one taxonomic structure into the categorial system of another such structure. Apparently on the basis of such taxonomic incommensurability, Kuhn asserted a number of antirealist theses about truth, reference and reality. In this paper, it will be argued, however, that, far from leading to antirealist consequences about the relationship between theory and reality, the taxonomic incommensurability thesis may be incorporated unproblematically within a reasonably robust scientific realist framework.
