Teleological Accounts of Mental Content

The purposes of this paper are first, to develop clearly the problem of mental conditionals for Millikan’s theory; second, to show why existing approaches to conditional semantics face serious challenges from a teleosemantic perspective; and third, to offer an account of the function of mental conditionals that meets the requirements of Millikan’s theory. We end up not only with a solution to a standing problem for teleosemantics, but also with a novel avenue for research in conditional semantics.

Naturalist theories of representation have been attacked on the grounds of being too liberal on the minimal conditions for intentionality: they treat several states that are not representational as genuine representations. Behind this attack lies the problem of demarcation: what are the minimal conditions for intentionality that a state should satisfy to be genuinely representational? What are the limits of intentionality? This paper develops a dual proposal to solve this problem. First, I defend the explanatory role criterion in order to (...) assess proposals of minimal conditions for intentionality. I start by proposing the success pattern condition: a state represents a given external feature provided that there is a success pattern present in the behavioural output, and the system uses this state as a proxy for the presence of this external feature. However, this condition is not sufficient for minimal intentionality – there are both intentional and non-intentional success patterns. Another minimal condition is, hence, required to draw this distinction. I propose the constancy mechanism condition: a state is representational provided that the system employs a constancy mechanism in its production. The success pattern and constancy mechanism conditions jointly constitute the dual proposal for minimal intentionality. I argue that this proposal is explanatorily justified and, so, properly demarcates the limits of intentionality. (shrink)

Representation in Cognitive Science, by SheaNicholas. Oxford: Oxford University Press, 2018. Pp. 292.

Over the past few decades, the dominant approach to explaining intentionality has been a naturalistic approach, one appealing only to non-mental ingredients condoned by the natural sciences. Karen Neander’s A Mark of the Mental (2017) is the latest installment in the naturalist project, proposing a detailed and systematic theory of intentionality that combines aspects of several naturalistic approaches, invoking causal relations, teleological functions, and relations of second-order similarity. In this paper, we consider the case of perceptual representations of colors, which (...) is a challenging case for Neander’s theory. This case will brings out a general methodological concern with Neander’s and other naturalistic theories: these theories generally rest on the assumption that the mental intentionality we are acquainted with in everyday life—the phenomenon exhibited by desires for cups of coffee, perceptual experiences of dogs playing in yards, and thoughts about the weather—is the very same kind of phenomenon that cognitive science studies under labels such as “mental representation” and, in some cases, “information processing.” This assumption is dubious, as the case of Neander’s theory illustrates.

“Teleosemantics and Pushmi-Pullyu Representations” argues that core teleosemantics, particularly as defined in Millikan :281–297, 1989, White queen psychology and other essays for Alice, MIT Press, Cambridge, 1993, Philosophical perspectives, Ridgeview Publishing, Alascadero, 1996, Varieties of meaning, MIT Press, Cambridge, 2004–2008), seems to imply that all descriptive representations are at the same time directive and that directives are at the same time descriptive, hence that all representations are pushmi-pullyu representations. A pushmi-pullyu representation is at once indicative and imperative, telling both what (...) the case is and what to do about it. The usefulness at all of the notion of a pushmi-pullyu representation is then questioned. I have recently found several new papers, dissertations, discussions, in which TP-PR is treated as definitive. However, the conclusions of TP-PR rest on misunderstandings of my position, so although the date is late, clarification seems still to be in order. I will indicate a few significant corrections that need to be made to TP-PR’s description of my position and explain central features of biosemantics that are omitted in TP-PR’s description of basic teleosemantics and which are incompatible with the main argument and conclusions of TP-PR. I will try to clarify and explain the value of the notion of a pushmi-pullyu representation. (shrink)

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that (...) teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

The indeterminacy problem is one of the most prominent objections against naturalistic theories of content. In this essay I present this difficulty and argue that extant accounts are unable to solve it. Then, I develop a particular version of teleosemantics, which I call ’explanation-based teleosemantics’, and show how this outstanding problem can be addressed within the framework of a powerful naturalistic theory.

Recent discussions of animal communication and the evolution of language have advocated adopting a ‘pragmatics-first’ approach, according to which “a more productive framework” for primate communication research should be “pragmatics, the field of linguistics that examines the role of context in shaping the meaning of linguistic utterances”. After distinguishing two different conceptions of pragmatics that advocates of the pragmatics-first approach have implicitly relied on, I argue that neither conception adequately serves the purposes of pragmatics-first approaches to the origins of human (...) linguistic communication. My main aim in this paper is to motivate–and begin to articulate–an intermediary conception whose scope is narrower than Carnapian pragmatics but broader than Gricean pragmatics. To do so, I first spell out what I take to be the key insight offered by proponents of the Gricean approach concerning the emergence of linguistic communication, namely, its being communication ‘from a psychological point of view’. I then develop this insight using key elements from the anti-Gricean ‘biosemantic’ account of linguistic communication due to Ruth Millikan, Philosophical Perspectives 9, Ridgeview Publishing, Atascedero CA, 1995, Millikan R Varieties of Meaning. Mass.: The MIT Press, Cambridge, Millikan, Beyond concepts: unicepts, language, and natural information, Oxford University Press, Oxford UK, 2017, and elsewhere). I argue that the intermediary pragmatics-first approach that I propose, which draws on both Gricean and Millikanian resources, would be better equipped to serve the purposes of those who search for potential precursors of human linguistic communication in animal communication.

Teleosemantics is the view that mental content depends on etiological function. Moral adaptationism is the view that human morality is an evolved adaptation. Jointly, these two views offer new venues for naturalist metaethics. Several authors have seen, in the conjunction of these views, the promise of assigning naturalistically respectable descriptive content to moral judgments. One such author is Neil Sinclair, who has offered a blueprint for how to conduct teleosemantic metaethics with the help of moral adaptationism. In this paper, I (...) argue that the prospects for assigning descriptive content to moral judgments on the basis of teleosemantics are bad. I develop my argument in dialogue with Sinclair’s paper and argue that, although Sinclair’s account of the evolution of morality is plausible, the teleosemantic account of the descriptive content of moral judgments which he bases thereon suffers from crucial shortcomings. I argue further that, given some minimal plausible assumptions about the evolution of morality made by Sinclair, no assignment of descriptive content is possible. Contrary to prevailing assumptions, the combination of moral adaptationism and teleosemantics suggests that moral judgments lack descriptive content. (shrink)

The teleosemantic indeterminacy problem has generated much discussion but no consensus. One possible solution is to accept indeterminacy as a real feature of some representations. I call this view “indeterminacy realism.” In this paper, I argue that indeterminacy realism should be treated as a serious option. By drawing an analogy with vagueness, I try to show that accepting the reality of indeterminacy would not be catastrophic for teleosemantics. I further argue that there are positive reasons to endorse indeterminacy realism. I (...) end the paper by arguing that indeterminacy realism need not generalize viciously to the case of propositional attitudes. (shrink)

Teleosemantics attempts to explain the content of mental representations through an appeal to functions, and typically attributes function to selection history. The narrowest cases focus on only evolutionary fitness benefit through natural selection, while broader theories have come to accept multiple levels of selection, including those over the course of a lifetime such as neural selection. The precise way to define function has given rise to many debates over the content of hypothetical mental representations. In this paper, I argue that (...) defining function through the lens of Nikolas Tinbergen’s levels of analysis provides a valuable framework in organizing and analyzing teleological theories of function, and can advance the debate into a more organized discourse. In particular, after defining and defending them on theoretical grounds, I go through three classic teleosemantic debates about content ascription and function and attempt to organize them in a Tinbergian framework in order to demonstrate their general applicability, followed by two more examples from humans and primates in order to give insight on the role of each level of analysis in cases where we have more direct internal access to the content of such representations. I finally suggest that a pluralist viewpoint of the content of representations in complex organisms may be justified. I argue that in light of Tinbergen’s levels of analysis framework, teleosemantic theories of mental content can be more clearly discussed and advanced. (shrink)

Representations may have descriptive content, directive content, or both, but little explicit attention has been given to the problem of distinguishing representations of these three kinds. We do not know, for instance, what determines whether a given representation is a directive instructing its consumer to perform some action or has descriptive content to the effect that the action in question has a certain value. This paper considers what it takes for a representation to have directive content. The first part of (...) the paper presents the Liberal View, which might be taken to be the default position on this issue. The Liberal View has some attractions, but as the second part shows, these are less conclusive than they might at first appear, and there is much to be said for an alternative, the Strict View.

“Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms. This essay critically explores (...) various interpretations of this analogy. It suggests that these interpretations can be explicated by contrasting adaptationist with pluralist readings of the evolutionary concept of adaptation. Among the possible interpretations of the relations between biological adaptations and their analogues in language and culture, the two most relevant are a linear, hierarchical, signalling-based model that takes its cues from the evolution of co-operation and joint intentionality and a mutualistic, pluralist model that takes its cues from mimesis and symbolism in the evolution of human communication. Arguing for the merits of the mutualistic model, the present analysis indicates a path towards an evolutionary pluralist version of biosemantics that will align with theories of cognition as being environmentally “scaffolded”. Language and other cultural forms are partly independent reproducible structures that acquire proper functions of their own while being integrated with organism-based cognitive traits in co-evolutionary fashion.

In a series of papers, Papineau argues that the Swampman scenario is not even the start of an objection to teleosemantics as a scientific reduction of belief. It is against this claim that I want to argue here. I shall argue that our intuition about the scenario questions the adequacy of the conceptual foundations of teleosemantics, namely, success semantics and the etiological conception of biological function, on which the explanatory power of the theory rests. In the course of argument, some (...) general connections between explanation and modality will be developed that shed a new light on Kripke’s analysis of necessary a posteriori propositions. The upshot will be that teleosemanticists should tackle the Swampman objection head-on. (shrink)

Although the definition of ‘signal’ has been controversial for some time within the life sciences, current approaches seem to be converging toward a common analysis. This powerful framework can satisfactorily accommodate many cases of signaling and captures some of its main features. This paper argues, however, that there is a central feature of signals that so far has been largely overlooked: its special causal role. More precisely, I argue that a distinctive feature of signals is that they are minimal causes. (...) I explain this notion, suggest some strategies for identifying its instances and defend its relevance by means of conceptual and empirical considerations. (shrink)

The pushmi-pullyu representation is a non-conjunctive representation with both descriptive and directive contents. Introduced by Millikan, the PPR is supposed to aid in explaining how organisms adapt behavior to environmental variance in the absence of intermediate inference. Until recently, it has led an uncontroversial theoretical life. However, Artiga has suggested that the PPR postulate conflicts with Millikan-style teleosemantics and, as a consequence, the PPR postulate should probably be set aside. I suggest here that the theoretical motivations for the PPR are (...) independent of any specific theory of naturalized content. If Artiga is right about the PPR’s incompatibility with Millikan-style teleosemantics, then that only reveals the inadequacy of Millikan-style teleosemantics. The PPR has a clear role to play in explaining the primitive systems that dominate the biosphere. However, Millikan did not want to limit the explanatory utility of the PPR to primitive systems but suggested that it has explanatory work to play in the animal signaling of complex organisms, Gibsonian affordances, as well as with distinctively human mental life and language. Contra Millikan, I suggest that the PPR has no or at best a very limited explanatory role to play in such cases. Further, the non-inferential feature of the PPR suggests that it should be understood at best as a marginal or borderline representation. (shrink)

One of the central tasks for naturalistic theories of representation is to say what it takes for something to be a representation, and some leading theories have been criticised for being too liberal. Prominent discussions of this problem have proposed a producer-oriented solution; it is argued that representations must be produced by systems employing perceptual constancy mechanisms. However, representations may be produced by simple transducers if they are consumed in the right way. It is characteristic of representations to be consumed (...) by systems which are capable of independent action. This paper defends this claim; discusses more precise, naturalistic formulations; and shows how it can illuminate the explanatory payoffs which science achieves by appealing to representation.

Representationalists have routinely expressed skepticism about the idea that inflexible responses to stimuli are to be explained in representational terms. Representations are supposed to be more than just causal mediators in the chain of events stretching from stimulus to response, and it is difficult to see how the sensory states driving reflexes are doing more than playing the role of causal intermediaries. One popular strategy for distinguishing representations from mere causal mediators is to require that representations are decoupled from specific (...) stimulus conditions. I believe this requirement on representation is mistaken and at odds with explanatory practices in sensory ecology. Even when sensory states have the job of coordinating a specific output with a specific input, we can still find them doing the work of representations, carrying information needed for organisms to respond successfully to environmental conditions. We can uncover information at work by intervening specifically on the information conveyed by sensory states, leaving their causal role undisturbed. (shrink)

Correctly understood, teleosemantics is the claim that “representation” is a function term. Things are called “representations” if they have a certain kind of function or telos and perform it in a certain kind of way. This claim is supported with a discussion and proposals about the function of a representation and of how representations perform that function. These proposals have been retrieved by putting together current descriptions from the literature on neural representations with earlier explorations of the features common to (...) most things we are inclined to call representations as these were assessed in Millikan. Of interest is the degree to which these independent sources converge. I conclude that there is no need to employ any new or technical sense of the term “representation” for it to play an important role in neuroscience. (shrink)

Teleosemantics explains mental representation in terms of etiological history: a mental state’s representational contents are the result of natural selection, or some other selection process. Critics have argued that the “swampman” thought experiment poses a counterexample to teleosemantics. In several recent papers, Papineau has argued that a merely possible swampman cannot serve as a counterexample to teleosemantics, but has acknowledged that actual swampmen would pose a problem for teleosemantics. In this paper, I argue that there are real-world cases of swampman-like (...) representation, in the form of functional tetrachromacy. People with functional tetrachromacy are born with four types of cones in each eye, rather than the usual three, and as a result can represent a wider variety of colors than the average person. I argue that the functional tetrachromat’s additional color representations are not the result of a selection process. Functional tetrachromacy is therefore a real-world case of mental representation without an etiological history, and therefore poses a genuine counterexample to teleosemantics. (shrink)

According to standard teleosemantics, intentional states are selectional states. This claim is put forward not as a conceptual analysis, but as a ‘theoretical reduction’—an a posteriori hypothesis analogous to ‘water = H2O’. Critics have tried to show that this meta-theoretical conception of teleosemantics leads to unacceptable consequences. In this paper, I argue that there is indeed a fundamental problem with the water/H2O analogy, as it is usually construed, and that teleosemanticists should therefore reject it. Fortunately, there exists a viable alternative (...) to the water/H2O model which avoids the fundamental problem, while explaining the a posteriori character of teleosemantics equally well. (shrink)

Hartry Field has proposed a fundamental division of theories of linguistic and mental content into those that do, and those that don’t, give a central role to ‘that’-clause ascriptions. Here I investigate the commitments of theories that (in accord with Field’s position) deny ‘that’-clause ascriptions a central role, but (in contrast to Field’s position) give truth conditions a central role. Such non-oblique truth-conditionalism promises significant advantages. However, the stance is costlier than it may appear. Non-oblique truth-conditionalists, I argue, must renounce (...) a priori entitlement to schemas of disquotation that are presupposed when theories of content are put to metaphysical or epistemological use. As case studies, I discuss two theories that might seem to exemplify non-oblique truth-conditionalism: David Chalmers’s two-dimensionalist theory of content and Ruth Millikan’s teleosemantics.

One of the issues of Philosophy of Mind is the intentionality of the mind. The topic of this article is the study of the two related aspects of this issue, i.e. the possibility of intentionality and how mind content is determined in the Teleological Theory of Mental Content. According to this theory, the natural evolution of a living organism and the teleological functions based on this determines mental content and one can present a natural and physical explanation of intentionality and (...) mental content with help from that. In this article, after explaining the foundations of this theory, i.e. realism in regards to intentionality, naturalism and the principle of natural evolution of species, we will first address two main versions of this theory, i.e. Dretske’s Indicator Semantics and Millikan Consumer Semantics and then evaluate them. The most important problem of this theory is that it cannot explain the content and meaning of philosophical and logical concepts nor non-existence concepts and therefore, it faces issues concerning the above concepts.

The generalized theory of evolution suggests that evolutionary algorithms apply to biological and cultural processes like language alike. Variation, selection and reproduction constitute abstract and formal traits of complex, open and often self-regulating systems. Accepting this basic assumption provides us with a powerful background methodology for this investigation: explaining the emergence and proliferation of semantic patterns, that become conventional. A teleosemantic theory of public (conventional) meaning (Millikan 1984; 2005) grounded in a generalized theory of evolution explains the proliferation of public (...) language forms in terms of their adaptive proper function. It has also been suggested, that the emergence of meaning, can be formalized with game-theoretical tools (Skyrms 2010) within signaling systems of coordination. I want to show how closely related these approaches are, both in terms of explanandum and of outcomes. To put it in a nutshell: If the emergence of public meaning can be satisfyingly explained in terms of signaling games, then the cultural evolutionary dynamics will serve as an adequate model to describe their proliferation. Public or conventional meaning (in contrast to personal meaning) can be fully understood in terms of its evolutionary function in a population of communicators. Furthermore, I want to argue how this understanding of conventional meaning could lead us to a strong semantic holism. (shrink)

A core feature of teleosemantic proposals has been to rely on selective history to justify semantic functional classification. Recently, Nanay and Bauer have offered ahistorical teleosemantic proposals intended to bypass the numerous criticisms arising from the dependence on history. However, part of the attraction of the traditional reliance on history is that it seemingly allowed teleosemantics to mesh with biological practice. For example, Millikan, a key advocate for the selective historical approach, argues that biological kind identity rests on historical relations. (...) That would seem to place ahistorical teleosemantics directly at odds with biological practice. I suggest that ahistorical teleosemantics need not conflict with biological practice. This reflects the fact that biological inquiry combines two complimentary explanatory strategies, essentialist and populational reasoning. The complementary character of these strategies allows ahistorical teleosemantics, as an instance of essentialism, to integrate with populational reasoning without conflict. (shrink)

This thesis offers a teleosemantic account of moral discourse and judgment. It develops a number of views about the function and content of moral judgments and the nature of moral discourse based on Ruth Millikan’s theory of intentional content and the functions of intentional attitudes. Non-cognitivists in meta-ethics have argued that moral judgments are more akin to desires and other motivational attitudes than to descriptive beliefs. I argue that teleosemantics allows us to assign descriptive content to motivational attitudes and hence (...) that even if the non-cognitivist is correct, moral judgments can be said to describe the world. Moreover, given further teleosemantic assumptions, this conclusion has consequences that are both surprising and interesting. First of all, while moral judgments have descriptive content, moral statements do not. The purpose of moral discourse is not to convey beliefs that are true simpliciter, but to convey attitudes that are descriptively correct when tokened by the addressee. Consequently, moral discourse requires speakers to adapt to hearers in order to secure their assent and bring them into "community of judgment" with themselves. Secondly, the descriptive content of a motivational attitude is partly a matter of the subject’s own preferences and circumstances. In particular, the descriptive correctness of a moral judgment is partly a function of the degree to which it is shared with others. Since a moral judgment also motivates the subject to spread it, it has the ability to, in a certain sense, make itself true. If regular descriptive beliefs are supposed to adapt the subject to the world, a moral judgment also has the capacity to adapt the world to the subject. (shrink)

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive version of (...) Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

The biological functions debate is a perennial topic in the philosophy of science. In the first full-length account of the nature and importance of biological functions for many years, Justin Garson presents an innovative new theory, the 'generalized selected effects theory of function', which seamlessly integrates evolutionary and developmental perspectives on biological functions. He develops the implications of the theory for contemporary debates in the philosophy of mind, the philosophy of medicine and psychiatry, the philosophy of biology, and biology itself, (...) addressing issues ranging from the nature of mental representation to our understanding of the function of the human genome. Clear, jargon-free, and engagingly written, with accessible examples and explanatory diagrams to illustrate the discussion, his book will be highly valuable for readers across philosophical and scientific disciplines.

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

According to Karen Neander’s causal-informational teleosemantics, the contents of perceptual states depend on the etiological response functions of sensory-perceptual systems. In this paper, I argue that this theory is, despite its virtues, unable to explain how humans and other animals are capable of perceiving properties with which no sensory-perceptual system has ever been confronted. After rejecting Neander’s own proposal in terms of second-order similarity and a proposal inspired by Ruth Millikan in terms of simplicity, I offer a solution which equates (...) functions with manifestations of dispositions that made a difference to evolutionary success. My suggestion is able to generate determinate and plausible contents for new perceptual states while still preserving the idea that etiological functions explain evolutionary success. (shrink)

Karen Neander's A Mark of the Mental is a noteworthy and novel contribution to the long-running project of naturalizing intentionality. The aim of the book is to “solve the part of Brentano’s problem that is within reach” (3). Brentano's problem is the problem of explaining intentionality; the part of this problem that is supposedly within reach is that of explaining nonconceptual sensory-perceptual intentionality; and Neander aims to solve it via an informational teleosemantic theory. In this review, we provide a chapter-by-chapter (...) summary followed by some discussion. We argue that Neander's theory yields incorrect predictions in some cases, that the methodological argument for informational teleosemantics does not succeed, and that it is not clear that the book makes contact with its initial target, the everyday phenomenon of intentionality.

Philosophers have traditionally held that propositions mark the domain of rational thought and inference. Many philosophers have held that only conceptually sophisticated creatures like us could have propositional attitudes. But in recent decades, philosophers have adopted increasingly liberal views of propositional attitudes that encompass the mental states of various non-human animals. These views now sit alongside more traditional views within the philosophical mainstream. In this paper I argue that liberalized views of propositional attitudes are so liberal that they encompass states (...) of all sorts of apparently mindless systems like circadian clocks in plants. I begin by arguing that on the most well-developed and widely endorsed theories of underived representation in philosophy, circadian clocks qualify as representations. I then argue that standard reasons for thinking that perceptual states and pictures have propositional content carry over to circadian clocks. Finally, I argue that circadian representations in plants play the kind of functional role that is widely taken to be partly constitutive of belief-like attitudes. So according to mainstream theories of representation, propositions, and attitudes, plants have propositional attitudes. Yet on other more traditional views, this conclusion would seem absurd. So, contrary to appearances, there is no shared, stable understanding of what propositional attitudes are in contemporary philosophy. (shrink)

Desires, or directive representations, are central components of human and animal minds. Nevertheless, desires are largely neglected in current debates about the naturalization of representational content. Most naturalists seem to assume that some version of the standard teleological approach, which identifies the content of a desire with a specific kind of effect that the desire has the function of producing, will turn out to be correct. In this paper I argue, first, that this common assumption is unjustified, since the standard (...) approach is in fact deeply problematic. Secondly, I propose an alternative account of the content of desires which, while generating plausible and determinate content ascriptions, avoids the main problem that plagues the standard approach, and is also preferable on other grounds.

Teleosemantics is the view that semantic classification is a species of functional classification. While it is plausible, I think, that there are semantic functions in the natural world, I want to suggest that not all semantic states are functional. An assumption commonly endorsed by the teleosemantist is that there is a distinction between accidental or incidental contributory effects and functions. However, endorsing that distinction, I will suggest, implies the theoretical possibility of nonfunctional semantics. In fact, plant-to-plant signaling might be an (...) actual instance of that theoretical possibility. (shrink)

A central idea in Ruth Millikan’s biosemantics is that a representation’s content is restricted to conditions required for the normal success of actions that it has as its function to guide. This paper raises and responds to a problem for this idea. The problem is that the success requirement seems to block us from saying that epistemic modal judgments represent our epistemic circumstances. For the normal success of actions guided by these judgments seems to depend on what is actually the (...) case, not on whether or to what extent various possibilities were supported by our evidence. In response, I argue, first, that actions guided by epistemic modal judgments have as their function to implement strategies for handling epistemic circumstances, second, that the successful performance of this function requires that aspects of these circumstances obtain, and, third, that biosemantics can thus understand epistemic modal judgments as representing these aspects. The recognition of such strategic contents introduces complications; I further argue that these are benign. (shrink)

One way to defend humane animal agriculture is to insist that the deaths of animals aren’t bad for them. Christopher Belshaw has argued for this position in the most detail, maintaining that death is only bad when it frustrates categorical desires, which he thinks animals lack. We are prepared to grant his account of the badness of death, but we are skeptical of the claim that animals don’t have categorical desires. We contend that Belshaw’s argument against the badness of animal (...) death relies on overly simplistic thought experiments and isn’t sufficiently careful in how it attributes mental states to animals. We present some cases of animal behavior from recent work on animal cognition that are most plausibly understood as spurred by categorical desires and we show how an independently plausible account of mental content—Ruth Millikan’s teleosemantics—supports our attribution of categorical desires in those cases. We end by arguing that even if you’re wary of our reliance on teleosemantics, you should still accept it due to considerations about moral risk. (shrink)

Teleological accounts of sensory normativity treat normal functioning for a species as a standard: sensory error involves departure from normal functioning for the species, i.e. sensory malfunction. Straightforward reflection on sensory trade-offs reveals that normal functioning for a species can exhibit failures of accuracy. Acknowledging these failures of accuracy is central to understanding the adaptations of a species. To make room for these errors we have to go beyond the teleological framework and invoke the notion of an ideal observer from (...) vision science. The notion of an ideal observer also sheds light on the important distinction between sensory malfunction and sensory limitation. (shrink)

A central goal of philosophy of perception is to uncover the nature of sensory capacities. Ideally, we would like an account that specifies what conditions need to be met in order for an organism to count as having the capacity to sense or perceive its environment. And on the assumption that sensory states are the kinds of things that can be accurate or inaccurate, a further goal of philosophy of perception is to identify the accuracy conditions for sensory states. In (...) this paper I recommend a novel approach to these core issues, one that draws heavily on game-theoretic treatments of signaling in nature. A benefit of the approach is that it helps us to understand why biologists attribute sensory powers to such a diverse range of organisms, including plants, fungi, and algae. (shrink)

Teleosemantic theories aspire to develop a naturalistic account of intentional agency and thought by appeal to biological teleology. In particular, most versions of teleosemantics study the emergence of intentionality in terms of biological purposes introduced by Darwinian evolution. The aim of this paper is to argue that the sorts of biological purposes identified by these evolutionary approaches do not allow for a satisfactory account of intentionality. More precisely, I claim that such biological purposes should be attributed to reproductive chains or (...) lineages, rather than to individual traits or organisms, whereas the purposes underlying intentional agency and thought are typically attributed to individuals. In the last part of the paper I suggest that related difficulties are also faced, despite appearances, by accounts of intentionality relying on alternative organizational approaches to biological teleology.

Perceptual representations are either correct or incorrect. Their correctness depends on their content and on the way the world is. Teleosemantics delivers compelling explanations of why our perceptual representations have contents, whereby it assigns the notion of "function" a central explanatory role. The author of this thesis engages in the search for a theory of function suited for this purpose. After a detailed evaluation of the selected effects​ theory and dispositional theories, the author argues that a synthesis is best suited (...) to be used by teleosemantics. (shrink)

It is widely held in contemporary philosophy of mind that states with underived representational content are ipso facto psychological states. This view—the Content View—underlies a number of interesting philosophical projects, such as the attempt to pick out a psychological level of explanation, to demarcate genuinely psychological from non-psychological states, and to limn the class of states with phenomenal character. The most detailed and influential theories of underived representation in philosophy are the tracking theories developed by Fodor, Dretske, Millikan and others. (...) Tracking theorists initially hoped to ‘naturalize’ underived representation by showing that although it is distinctively psychological it is not irreducibly so, yet they ended up developing theories of representation that by their own lights don’t pick out a distinctively psychological phenomenon at all. Burge sets out to develop a theory of underived representation that does pick out a distinctively psychological phenomenon. His theory promises to vindicate the Content View and the various philosophical projects that depend on it. In this paper I argue that Burge’s theory dementalizes representation for the same reason tracking theories do: These theories hold that representations are states with underived accuracy conditions, yet such states are found in all sorts of mindless systems, like plants.

Both Millikan’s brand of naturalistic analytic philosophy and Husserlian phenomenology have held on to teleological notions, despite their being out of favor in mainstream Western philosophy for most of the twentieth century. Both traditions have recognized the need for teleology in order to adequately account for intentionality, the need to adequately account for intentionality in order to adequately account for meaning, and the need for an adequate theory of meaning in order to precisely and consistently describe the world and life. (...) The stark differences between their accounts of these fundamental concepts stem from radically different conceptions of the world, the natural and life. I argue that Millikan’s teleosemantic approach relies on a teleology of determination by means of the lawfulness of nature that leaves no room for the freedom of self-determination, for reason, or for experience—for the reality of lived human life. In contrast to Millikan’s account, Husserl’s transcendental phenomenology situates teleology as a function of reason and first-personal experience, part of an extended account of intentionality and meaning according to which the full range of our making sense of the world is conceived as a rational activity that is itself a part of that world, and not an unnatural activity to be separated from it. While Husserl’s account of these issues is indeed symptomatic of what Millikan calls “meaning rationalism,” I argue that it is immune to the sorts of problems she claims will plague any such account, since these problems arise only against the background of a set of presuppositions about intentionality that Husserl does not share. Husserl’s position can itself be understood to be within the bounds of a suitably liberal conception of naturalism, and interpreting him in this way it has the added benefit—contra Millikan—of not divorcing teleology from reason, the latter construed as our first-personal striving to make sense of the world as we experience it—of life.

Perceptual representations have distal content: they represent external objects and their properties, not light waves or retinal images. This basic fact presents a fundamental problem for ‘input-oriented’ theories of perceptual content. As I show in the first part of this paper, this even holds for what is arguably the most sophisticated input-oriented theory to date, namely Karen Neander's informational teleosemantics. In the second part of the paper, I develop a new version of informational teleosemantics, drawing partly on empirical psychology, and (...) partly on philosophical considerations. I shall argue that this version has all the virtues of Neander's original theory, but also the further crucial advantage of being able to account for the distality of perceptual content. (shrink)

In this essay, we draw on John Haugeland’s work in order to argue that Burge is wrong to think that exercises of perceptual constancy mechanisms suffice for perceptual representation. Although Haugeland did not live to read or respond to Burge’s Origins of Objectivity, we think that his work contains resources that can be developed into a critique of the very foundation of Burge’s approach. Specifically, we identify two related problems for Burge. First, if (what Burge calls) mere sensory responses are (...) not representational, then neither are exercises of constancy mechanisms, since the differences between them do not suffice to imply that one is representational and the other is not. Second, taken by themselves, exercises of constancy mechanisms are only derivatively representational, so merely understanding how they work is not sufficient for understanding what is required for something, in itself, to be representational (and thereby provide a full solution to the problem of perceptual representation).

The dominant view in teleosemantics is that semantic functions are historically determined. That reliance on history has been subject to repeated criticism. To sidestep such criticisms, Nanay has recently offered an ahistorical alternative that swaps out historical properties for modal properties. Nanay's ahistorical modal alternative suffers, I think, serious problems of its own. I suggest here another ahistorical alternative for teleosemantics. The motivation for both the historical view and Nanay's is to provide a naturalistic basis to characterize some item as (...) possessing a function independent of its actual performance and, thereby, provide a grip on intentional inexistence and misrepresentation. I suggest that attending to the logic of mechanistic explanation suffices to provide the sought for naturalistic basis. The key advantage to the approach offered here is its relative parsimony: unlike its alternatives, it requires no substantive existential commitments, for example, commitments to natural selection, copying relations, or fitness-enhancing modal properties, to naturalize semantic content.
