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.

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.

Maybe they should never have called the first movie The Terminator. After all, there’s more than one Terminator. That may seem like a picky point, but, believe it or not, philosophers have long been obsessed with trying to determine the meaning of the word “the.†Indeed, much controversy swirls around this seemingly innocuous definite article. Specifically, the controversy focuses on whether or not definite descriptions are ambiguous.

As is well known, we can prove that everything that exists necessarily exists in S5. Perhaps as well known is Kripke’s two-part solution. First we forbid axioms with free variables and second we forbid the use of singular terms. One way to do the latter is via Nominal Description Theory (NDT): a name N is semantically equivalent to the description that mentions the name, e.g. ‘the-bearer-of-“N”’. But how do we reconcile NDT with the thesis of rigid designation? I argue that (...) we need to distinguish a semantic theory that aims to give an account of thoughts (P-semantics) from one that aims to give an account of English sentence types (L-semantics). I then introduce frigidity as the claim that there are no L-semantic singular terms. The causal theory of reference is a P- semantic theory and together with NDT we can then formulate L-semantic descriptions that cap.. (shrink)

Everyone knows that moogles are disgustingly cute. I know people who would kill to be able to have one in real life, but could there really be moogles? Say, for instance, that archeologists discovered a species of animal in some remote land that completely resembled the chocobo in every way. Would that count as discovering that the beloved Final Fantasy creatures were real? Even if we don’t make such a discovery are chocobos and moogles metaphysically possible? That is, can we (...) coherently imagine a situation which would count as one which contained moogles? The answer to these questions depends, surprisingly, on what the meaning of ‘moogle’ and ‘chocobo’ is; or so many contemporary philosophers of language think. In particular one contemporary philosopher, Saul Kripke (1940- ), has argued that the answer to both of these questions is a resounding no. In order to understand why he thinks this and whether he is right we’ll have to begin by looking at the debate philosophers have had over the meaning of names. (shrink)

A standard view of reference holds that a speaker's use of a name refers to a certain thing in virtue of the speaker's associating a condition with that use that singles the referent out. This view has been criticized by Saul Kripke as empirically inadequate. Recently, however, it has been argued that a version of the standard view, a _response-based theory of reference_, survives the charge of empirical inadequacy by allowing that associated conditions may be largely or even entirely implicit. (...) This paper argues that response-based theories of reference are prey to a variant of the empirical inadequacy objection, because they are ill-suited to accommodate the successful use of proper names by pre-school children. Further, I argue that there is reason to believe that normal adults are, by and large, no different from children with respect to how the referents of their names are determined. I conclude that speakers typically refer _positionally_: the referent of a use of a proper name is typically determined by aspects of the speaker's position, rather than by associated conditions present, however implicitly, in her psychology.

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality is preserved via purely (...) abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

Realistic uses of Virtual Reality (VR) technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception (ITP) may be extended to cover such cases. Virtual objects are explained as concrete models (CMs) that have an inner generation mechanism, and the ITP is used to explain how VR users can both perceive such local CMs, and perceptually represent remote real objects. Also, concepts of modeling and representation are (...) distinguished. The paper concludes with suggestions as to how the ITP methodology developed here could be extended to iconic external representations and models generally. (shrink)

A concrete proposal is presented as to how semantics should be naturalized. Rather than attempting to naturalize propositions, they are treated as abstract entities that index concrete cognitive states. In turn the relevant concrete cognitive states are identified via perceptual classifications of worldly states, with the aid of an interactive theory of perception. The approach enables a broadly realist theory of propositions, truth and cognitive states to be preserved, with propositions functioning much as abstract mathematical constructs do in the nonsemantic (...) sciences, but with a much more specific propositional indexing scheme than previous naturalistic proposals were able to achieve. (shrink)

A novel semantic naturalization program is proposed. Its three main differences from informational semantics approaches are as follows. First, it makes use of a perceptually based, four-factor interactive causal relation in place of a simple nomic covariance relation. Second, it does not attempt to globally naturalize all semantic concepts, but instead it appeals to a broadly realist interpretation of natural science, in which the concept of propositional truth is off-limits to naturalization attempts. And third, it treats all semantic concepts as (...) being purely abstract, so that concrete cognitive states are only indexed by them rather than instantiating them. (shrink)

This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philosophical constraints, as enumerated and discussed in Section 1 below. A perceptual theory invoking _reflexive dispositions_--that is, dispositions directed toward the very (...) same worldly perceived objects or properties that caused them--will be defended as one legitimate such naturalistic theory. (shrink)

Causal theories of perception typically have problems in explaining deviant causal chains. They also have difficulty with other unusual putative cases of perception involving prosthetic aids, defective perception, scientifically extended cases of perception, and so on. But I show how a more adequate reflexive causal theory, in which objects or properties X cause a perceiver to acquire X-related dispositions toward that very same item X, can provide a plausible and principled perceptual explanation of all of these kinds of cases. A (...) critical discussion of David Lewis's perceptual descriptivist views is also provided, including a defense of the logical possibility of systematic misperception or perceptual error for a perceiver, in spite of its empirical improbability.

ABSTRACT: The Reflexive Theory of Perception (RTP) claims that perception of an object or property X by an organism Z consists in Z being caused by X to acquire some disposition D toward X itself. This broadly behavioral perceptual theory explains perceptual intentionality and correct versus incorrect, plus successful versus unsuccessful, perception in a plausible evolutionary framework. The theory also undermines cognitive and perceptual modularity assumptions, including informational or purely epistemic views of perception in that, according to the RTP, any (...) X-caused and X-directed dispositions are genuinely perceptual—including affective, attitudinal, and immediately activated purely action-directed behavioral dispositions. Thus the RTP has the potential to provide the foundations for a broadly behavioral counter-revolution in cognitive science. (shrink)

The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of informational concepts. (...) However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views.

A lot of us have given up on the idea that there will be a naturalistic account of the relation of semantic reference and so have resolved to formulate our theories of semantics and communication without appeal to semantic reference. Still, there is a resilient intuition to the effect that I know the extensions of the terms of my language. This paper explicates that intuition without yielding to it. The key idea is to give a “skeptical” account of what it (...) is to “know the meaning” of a word, by which I mean an account of the status that is granted to a person in saying that he or she “knows the meaning” of a word.

A review of Devitt and Sterelny, Language and Reality (1st edition).

Direct reference theorists tell us that proper names have no semantic value other than their bearers, and that the connection between name and bearer is unmediated by descriptions or descriptive information. And yet, these theorists also acknowledge that we produce our name-containing utterances with descriptions on our minds. After arguing that direct reference proponents have failed to give descriptions their due, I show that appeal to speaker-associated descriptions is required if the direct reference portrayal of speakers wielding and referring with (...) public names is to succeed.

Orthodox neural materialists think mental states are neural events or orthodox material properties of neutral events. Orthodox material properties are defining properties of the “physical”. A “defining property” of the physical is a type of property that provides a necessary condition for something’s being correctly termed “physical”. In this paper I give an argument against orthodox neural materialism. If successful, the argument would show at least some properties of some mental states are not orthodox material properties of neural events. Oppositing (...) philosophical orthodoxy, I show there are no posteriori identities -- identities that cannot be known of a priori. (shrink)

Functionalists think an event's causes and effects, its 'causal role', determines whether it is a mental state and, if so, which kind. Functionalists see this causal role principle as supporting their orthodox materialism, their commitment to the neuroscientist's ontology. I examine and refute the functionalist's causal principle and the orthodox materialism that attends that principle.

Spencer’s heritage, while almost a forgotten chapter in the history of biology, lives on in psychology and the philosophy of mind. I particularly discuss externalist views of meaning, on which meaning crucially depends on a notion of reference, and ask whether reference should be thought of as cause or effect. Is the meaning of a word explained by what it refers to, or should we say that what we use a word to refer to is explained by what concept it (...) expresses? I argue for the latter view, which I call ‘Darwinian’, and against the former, ‘Spencerian’ one, assuming conceptual structures in humans to be an instance of adaptive structures, and adaptive relations to an environment to be the effect rather than the cause of evolutionary novelties. I conclude with the deficiency – both empirically and methodologically – of a functionalist study of human concepts and the languages they are embedded in, as it would be undertaken in a paradigm that identifies meaning with reference or that gives reference an explanatory role to play for what concepts we have.

'If a person can think of an F, then that person has come into causal contact with an F in the right way' is a premise in an obvious reconstruction of Putnam's argument that we are not brains in vats. 'If a person can think of an F, then that person has come into causal contact with an F or with something at least as good as an F' is the only controversial premise in Descartes' argument for the existence of (...) God. Putnam's principle entails Descartes', which suggests that we should enquire after better versions of Putnam's proof. I present three variations and conclude that Putnam's semantic theory does not have anti-sceptical consequences. In contrast, given Descartes' cognitive situation, he was perfectly justified in accepting the soundness of his argument for the existence of God. (shrink)

If there is such a thing as essential reading in metaphysics or in philosophy of language, this is it.

The causal theory of reference is often taken to provide a solution to the problems, such as incomparability and referential discontinuity, that the meaning-change thesis raised. I show that Kuhn successfully questioned the causal theory and Putnam's idea that reference is determined via the sameness relation of essences that holds between a sample and other members of a kind in all possible worlds. Putnam's single ‘essential' properties may be necessary but not sufficient to determine membership in a kind category. Kuhn (...) argued that extension is fixed by similarity-dissimilarity relations that are liable to change in taxonomic reorganizations of science. *Received October 2009; revised January 2010. †To contact the author, please write to: Institute of Philosophy, University of Leiden, Martin de Vrieshof 4, 2300 RS Leiden, The Netherlands; e-mail: j.kuukkanen@phil.leidenuniv.nl.

Theories of reference have been central to analytic philosophy, and two views, the descriptivist view of reference and the causal-historical view of reference, have dominated the field. In this research tradition, theories of reference are assessed by consulting one’s intuitions about the reference of terms in hypothetical situations. However, recent work in cultural psychology (e.g., Nisbett et al. 2001) has shown systematic cognitive differences between East Asians and Westerners, and some work indicates that this extends to intuitions about philosophical cases (...) (Weinberg et al. 2001). In light of these findings on cultural differences, two experiments were conducted which explored intuitions about reference in Westerners and East Asians. Both experiments indicate that, for certain central cases, Westerners are more likely than East Asians to report intuitions that are consistent with the causal-historical view. These results constitute prima facie evidence that semantic intuitions vary from culture to culture, and the paper argues that this fact raises questions about the nature of the philosophical enterprise of developing a theory of reference. (shrink)

Machery et al. (2004) reported some preliminary evidence that intuitions about reference vary within and across cultures, and they argued that if real, such variation would have significant philosophical implications (see also Mallon et al. 2009). In a recent article, Genoveva Martı´ (2009) argues that the type of intuitions examined by Machery and colleagues (‘metalin- 10 guistic intuitions’) is evidentially irrelevant for identifying the correct theory of reference, and she concludes that the variation in the relevant intuitions about reference within (...) and across cultures has not been established. (shrink)

It is common in various quarters of philosophy to derive philosophically significant conclusions from theories of reference. In this paper, we argue that philosophers should give up on such ‘arguments from reference.’ Intuitions play a central role in establishing theories of reference, and recent cross-cultural work suggests that intuitions about reference vary across cultures and between individuals within a culture (Machery et al. 2004). We argue that accommodating this variation within a theory of reference undermines arguments from reference.

It has been suggested that the theory of reference advanced by Kripke and Putnam implies, or presupposes, an aristotelian vision of natural kinds and essences. I argue that what is in fact established is that there are degrees of naturalness among kinds. A parallel argument shows that there are degrees of naturalness among individuals. A subsidiary theme of the paper is that the definition of "natural kind term" as "rigid designator of a natural kind" is mistaken. Names and natural kind (...) terms are defined by ostension to a spatiotemporal part of what they ostend. This helps us understand why 'Hesperus' and 'Phosphorus' are cognitively non-equivalent.

Abstract I propose to support these replies with actual episodes in late nineteenth and twentieth century physics. The historical record reveals that meaning does change but not in the Kuhnian manner which is tied to descriptive theories of meaning. A necessary part of this discussion is commentary on realist versus antirealist conceptions of science.

In this paper [submitted in 2008] I discuss the relation between truth and assertion, starting from Linsky's example [her husband is kind to her], used in the debate on definite description by Keith Donnellan and Saul Kripke. To treat the problem of the referential use of definite descriptions we need not only to take into account the contest of utterance, but also the context of reception, or the cognitive context. If the cognitive context is given the right relevance we may (...) even accept the possibility to speak of "pragmatic ambiguity" as Donnellan did. However I will not give a definite answer to the debate between Donnellan and Kripke, but I will try to show that there is a moral to be drawn by the discussion: it is advisable to use truth attribution in a charitable way if we want to entertain conversation with people who have beliefs not necessarily similar to ours.

The work of Kripke, Putnam, Kaplan, and others initiated a tradition in philosophy that has come to be known as anti-descriptivism. I argue that when properly interpreted, Wilfrid Sellars is a staunch anti-descriptivist. Not only does he accept most of the conclusions drawn by the more famous anti-descriptivists, he goes beyond their critiques to reject the fundamental tenant of descriptivism—that understanding a linguistic expression consists in mentally grasping its meaning and associating that meaning with the expression. I show that Sellars’ (...) alternative accounts of language and the mind provide novel justifications for the anti-descriptivists’ conclusions. Finally, I present what I take to be a Sellarsian analysis of an important anti-descriptivist issue: the relation between metaphysical modal notions (e.g., possibility) and epistemic modal notions (e.g., conceivability). The account I present involves extension of the strategy he uses to explain both the relation between physical object concepts (e.g., whiteness) and sensation concepts (e.g., the appearance of whiteness), and the relation between concepts that apply to linguistic activity (e.g., sentential meaning) and those that apply to conceptual activity (e.g., thought content).

Machery, Mallon, Nichols, and Stich [2004; forthcoming] use experimental methods to raise a spectre of doubt about reliance on intuitions in developing theories of reference which are then deployed in philosophical arguments outside the philosophy of language. Machery et al. ran a cross-cultural survey asking Western and East Asian participants about a famous case from the philosophical literature on reference (Kripke's G del example). They interpret their results as indicating that there is significant variation in participants' intuitions about semantic reference (...) for that case. We argue that this interpretation is mistaken. We detail a type of ambiguity found in Machery et al.'s probe but not yet noted in the response literature. We argue that this epistemic ambiguity could have affected their results. We do not stop there, however: Rather than rest content with a possibility claim, we ran four studies to test the impact of this ambiguity on participants' responses. We found that this accounts for much of the variation in Machery et al.'s original experiment. We conclude that in the light of our new data, their argument is no longer convincing. (shrink)
