Few philosophers today doubt the importance of some notion of rigid designation, as suggested by Kripke and Putnam for names and natural kind terms. At the very least, most of us want our theories to be compatible with the most plausible elements of that account. Anaphoric theories of reference have gained some attention lately, but little attention has been given to how they square with rigid designation. Although the differences between anaphoric theories and many interpretations of the New Theory of reference are substantial, I argue that rigid designation and anaphoric theories can be reconciled with one another and in fact complement one another in important ways.

Semantic externalism about a class of expressions is often thought to make conceptual analysis about members of that class impossible. In particular, since externalism about natural kind terms makes the essences of natural kinds empirically discoverable, it seems that mere reflection on one's natural kind concept will not be able to tell one anything substantial about what it is for something to fall under one's natural kind concepts. Many hold the further view that one cannot even know anything substantial about the reference-fixers of one's natural kind concepts by armchair reflection. In this paper I want to question this latter view and claim that, because of the way our standard methodology of doing theories of reference relies on semantic intuitions, typical externalists in fact presuppose that one can know the reference-fixers of one's natural kind concepts by mere armchair reflection. The more interesting question is how substantial such knowledge can be. I also take some steps toward answering this question.

Algunas de las objeciones más importantes contra la tesis de la incommensurabilidad, especialmente en su versión referencial se basan en la teoría causal de la referencia y, en particular, en la teoría de la referencia de Putnam acerca de los términos de género natural: de estl teoría se sigue que la referencia de los términos de género natural no se ve modificada por cambios en nuestras teorías. En este articulo examino la teoria de la referencia de Putnam y arguyo que esta no permite rebatir la tesis de la incommensurabilidad referencial. Mi examen se centra en la referencia de un tipo de términos de genera natural los terminos de sustancia y, en concreto, en la referencia deI término “agua”.Some of the most imporant objections against the incommensurability thesis, especially in its referential version, are based on tbe causal theory of reference and, in particular, on Putnam’s reference theory about natural kind terms; from this theory it follows that the reference of natural kind terms is not modified by changes in our theories. In this paper I examine Putnam’s theory of reference and argue that it does not countenance a refutation of the thesis of referential incommensurability. My examination concentrates on the reference of one sort of natural kind terms, substance terms, and specifically on tbe reference of the term “water”.

In this paper I question Devitt and Sterelny’s proposal that reference borrowing is a causal process and that the reference borrower is ignorant about the referent.I argue that borrowers need to have some true beliefs about the referent. If so, reference borrowing involves a causal chain of communication together with some associated description. The conclusion is that what is needed for reference borrowing of other kind terms is also needed for the natural kind terms. There is no need to posit a difference between the two. Thus as you cannot refer to daggers by ‘dagger’ unless you realize that they are edged weapons, so you cannot refer to tigers by ‘tiger’ unless you realize that they are animals of a certain sort. The theory of reference borrowing that we need here in both cases seems to be descriptive-causal and not only causal.If the traditional views of borrowing have demanded too much of individual speakers, the causal picture surely demands too little. Mere causal connection with some antecedent tradition of name use does not suffice for the preservation of reference.

In this exchange with Michael Devitt on reference borrowing I continue to challenge the idea that reference borrowing is a purely causal process and suggest instead that reference borrowing involves the borrowers having to associate the correct categorial term and have some true beliefs about the referent in the guise of some associate description. I strengthen my defense by suggesting that other kind terms form the core of our language and this is where we associate true categorial descriptions and where error would matter. I also argue that in reference borrowing there is no need to posit a difference between proper names and natural kind terms on one hand and other kind terms on the other. If the traditional views of reference borrowing have demanded too much of individual speakers, the causal picture surely demands too little. Mere causal connection to some antecedent tradition of term use does not suffice for the preservation of reference.

This paper uses an example from biology, the homology concept, to argue that current versions of the causal theory of reference give an incomplete account of reference determination. It is suggested that in addition to samples and stereotypical properties, the scientific use of concepts and the epistemic interests pursued with concepts are important factors in determining the reference of natural kind terms.

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.

While purely causal theories of reference have provided a plausible account of the meanings of names and natural kind terms, they cannot handle vacuous theoretical terms. The causal homeostasis theory can but incurs other difficulties. Theories of reference that are intensional and not purely causal tend to be molecularist or holist. Holist theories threaten transtheoretic reference, whereas molecularist theories must supply a principled basis for selecting privileged meaning-determining relations between terms. The causal homeostasis theory is a two-factor (causal and intensional) molecularist theory, but it fails to provide such a principled basis and collapses into holism. A naturalistic, non-foundationalist holism that deploys strategies of intertheoretic reduction and co-evolutionary pluralism can, however, yield a credible version of transtheoretic reference.

Contemporary debates about the nature of semantic reference have tended to focus on two competing approaches: theories which emphasize the importance of descriptive information associated with a referring term, and those which emphasize causal facts about the conditions under which the use of the term originated and was passed on. Recent empirical work by Machery and colleagues suggests that both causal and descriptive information can play a role in judgments about the reference of proper names, with findings of cross-cultural variation in judgments that imply differences between individuals with respect to whether they favor causal or descriptive information in making reference judgments. We extend this theoretical and empirical line of inquiry to views of the reference of natural and nominal kind concepts, which face similar challenges to those concerning the reference of proper names. In two experiments, we find evidence that both descriptive and causal factors contribute to judgments of concept reference, with no reliable differences between natural and nominal kinds. Moreover, we find evidence that the same individuals’ judgments can rely on both descriptive and causal information, such that variation between individuals cannot be explained by appeal to a mixed population of “pure descriptive theorists” and “pure causal theorists.” These findings suggest that the contrast between descriptive and causal theories of reference may be inappropriate; intuitions may instead support a hybrid theory of reference that includes both causal and descriptive factors. We propose that future research should focus on the relationship between these factors, and describe several possible frameworks for pursuing these issues. Our findings have implications for theories of semantic reference, as well as for theories of conceptual structure.

In this thesis I argue that the psychological study of concepts and categorisation, and the philosophical study of reference are deeply intertwined. I propose that semantic intuitions are a variety of categorisation judgements, determined by concepts, and that because of this, concepts determine reference. I defend a dual theory of natural kind concepts, according to which natural kind concepts have distinct semantic cores and non-semantic identification procedures. Drawing on psychological essentialism, I suggest that the cores consist of externalistic placeholder essence beliefs. The identification procedures, in turn, consist of prototypes, sets of exemplars, or possibly also theory-structured beliefs. I argue that the dual theory is motivated both by experimental data and theoretical considerations. The thesis consists of three interrelated articles. Article I examines philosophical causal and description theories of natural kind term reference, and argues that they involve, or need to involve, certain psychological elements. I propose a unified theory of natural kind term reference, built on the psychology of concepts. Article II presents two semantic adaptations of psychological essentialism, one of which is a strict externalistic Kripkean-Putnamian theory, while the other is a hybrid account, according to which natural kind terms are ambiguous between internalistic and externalistic senses. We present two experiments, the results of which support the strict externalistic theory. Article III examines Fodor’s influential atomistic theory of concepts, according to which no psychological capacities associated with concepts constitute them, or are necessary for reference. I argue, contra Fodor, that the psychological mechanisms are necessary for reference.
