This paper examines the "causal theory of reference", according to which science aims at the discovery of "essences" which are the objects of reference of natural kind terms (among others). This theory has been advanced as an alternative to traditional views of "meaning", on which a number of philosophical accounts of science have relied, and which have been criticized earlier by the present author. However, this newer theory of reference is shown to be equally subject to fatal internal difficulties, and to be incompatible with actual science as well. Indeed, it rests on assumptions which it shares with the purportedly opposing theory of meaning. Behind those common assumptions is the supposition that the nature of science can be illuminated by an examination of alleged necessities of language which are independent of the results and methods of scientific inquiry. An alternative view of science is proposed, according to which the goals and language of science develop as integral parts of the process of demarcating science from non-science, a process in which the notion of a "reason" gradually assumes a decisive role. On this view, the comparability, competition, and development of scientific ideas are understood without reliance on either common "meanings" or common "references" as fundamental tools of analysis.

The paper discusses reference determination from the point of view of conceptual change in science. The first part of the discussion uses the homology concept, a natural kind term from biology, as an example. It is argued that the causal theory of reference gives an incomplete account of reference determination even in the case of natural kind terms. Moreover, even if descriptions of the referent are taken into account, this does not yield a satisfactory account of reference in the case of the homology concept. I suggest that in addition to the factors that standard theories of reference invoke the scientific use of concepts and the epistemic interests pursued with concepts are important factors in determining the reference of scientific concepts. In the second part, I argue for a moderate holism about reference determination according to which the set of conditions that determine the reference of a concept is relatively open and different conditions may be reference fixing depending on the context in which this concept is used. It is also suggested that which features are reference determining in a particular case may depend on the philosophical interests that underlie reference ascription and the study of conceptual change.

The paper gives an overview of key themes of twentieth century philosophical treatment of the language of science, with special emphasis on the meaning variance of scientific terms and the comparison of alternative theories. These themes are dealt with via discussion of the topics of: (a) the logical positivist principle of verifiability and the problem of the meaning of theoretical terms, (b) the postpositivist thesis of semantic incommensurability, and (c) the scientific realist response to incommensurability based on the causal theory of reference.

A number of important legal theorists have recently argued for metaphysically realist approaches to legal determinacy grounded in particular semantic theories or theories of reference, in particular, views of meaning and reference based on the works of Putnam and Kripke. The basic position of these theorists is that questions of legal interpretation and legal determinacy should be approached through semantic meaning. However, the role of authority (in the form of lawmaker choice) in law in general, and democratic systems in particular, require that these realist solutions to the problem of legal determinacy be rejected, or at least significantly revised.

Some years ago, Howard Wettstein provided an original defense of the New Theory of Reference (NTR), the doctrine that singular terms such as names and indexicals are directly referential terms (DRTs), contributing only their reference to the truth-conditions of the tokened sentence they occur in. Wettstein maintained that in order to be semantically adequate, NTR does not have to account for what he calls Frege’s data on cognitive significance, those puzzling facts about language that prompt one to think that meaning entails more than reference to (real) objects. He later put forward another, apparently paradoxical, thesis, namely that whatever this cognitive significance that explains Frege’s data is, it cannot be reduced to the representations one has in one’s mind. In what follows, however, I will first apply the notion of referential anaphorical transfer to mixed contexts in order to show that a New Theorist has to reject Wettstein’s initial thesis as it stands, although she may endorse a weaker version of it, one that especially tallies with his second thesis. I will further argue that, insofar as rejecting Wettstein’s initial thesis does not force the New Theorist to revert to a representional conception of cognitive significance, in particular one based on the notion of a mental file, the latter thesis is absolutely correct. It is thus fitted to become a cornerstone of the New Theory, whatever form of non-mentalistic interpretation the New Theorist might wish to give to the notion of cognitive significance.

A holistic account of the meaning of theoretical terms leads scientific realism into serious troubles. Alternative methods of reference fixing are needed by a realist who wishes to show how reference invariance is possible in spite of meaning variance. This paper argues that the similarity theory of truthlikeness and approximate truth, developed by logicians since the mid 1970s, helps to make precise the idea of charitable theoretical reference. Comparisons to the recent proposals by Kitcher and Psillos are given. This argument helps to undermine the scepticist meta-induction about theories, and thereby to reevaluate Laudan's alleged confutation of scientific realism.

Summary One of the central questions concerning theories of reference has been the problem of how the reference of scientific terms gets fixed. Descriptive causal theories of reference, as discussed in this paper, have re-introduced the role of theoretical beliefs and conceptualisations in term introductions and reference-fixing. The present paper argues that the idea of reference-fixing as a dot-like event (baptism) is wrong: a number of episodes from the history of science are discussed to support the claim that reference-fixing is a historical, drawn-out process. This, however, does not stand in the way of successful reference. The two processes are simply separated. A criterion is suggested to determine successful reference. From this approach two further ideas follow: not all scientific terms actually have the power of referring and even those that do will always retain a residual indeterminacy.

How can the reference of theoretical terms be stable over changes of theory? I defend an approach to this that does not depend on substantive metasemantic theories of reference. It relies on the idea that in contexts of use, terms may play a role in a theory that in turn points to a further (possibly unknown) theory. Empirical claims are claims about the nature of the further theories, and the falsification of these further theories is understood not as showing that a term in the original theory fails to refer, but rather that a scientific hypothesis encapsulated by the further theory is mistaken.

In this essay I present a statement of Quine's indeterminacy thesis in its general form. It is shown that the thesis is not about difficulties peculiar to so-called "radical translation." It is a general thesis about meaning and reference with important consequences for any theory of our theories and beliefs. It is claimed that the thesis is inconsistent with Quine's realism, his doctrine of the relativity of reference, and that the argument for the thesis has the consequence that the concept of stimulus meaning is empty. The sense in which linguistic science, as a branch of behavioral science, is "part of physics" is discussed. An alternative to Quine's view of the nature and content of linguistic science is proposed. It is shown to be consistent with Quine's assumptions concerning the legitimate scope of behavioral science and not to involve the notions of analyticity, synonymy and "prevalent attitudes toward meaning, idea and proposition" ([9], p. 304) rejected by Quine.

The New Theory of Reference (NTR) of Marcus, Kripke, Kaplan, Putnam and others is a theory in the philosophy of language and there has been much debate about whether it entails the metaphysical theory of essentialism. But there has been no discussion about whether the NTR entails another metaphysical theory, the absolutist theory of time and space. It is argued in this paper that the NTR carries this entailment; the theory of time is the main focus of the paper and it is argued that the NTR entails the absolutist theory that times are event-independent moments.
