My dissertation establishes the basis for a systematic outlook on the role language plays in human cognition. It is an investigation based on a cognitive conception of language, as opposed to communicative conceptions, viz. those that suppose that language plays no role in cognition. I focus, in Chapter 2, on three paradigmatic theories adopting this perspective, each offering different views on how language contributes to or changes cognition. -/- In Chapter 3, I criticize current views held by dual-process theorists, and (...) I develop a picture of the complex interaction between language and cognition that I deem more plausible by using resources from the literature on the evolution of the faculty of language. Rather than trying to find one general explanation for all cognitive processes, I take seriously the idea that our mind is composed of many subsystems, and that language can interact and modify each in different ways. There is no reason offered in the empirical literature—besides maybe parsimony—that suggest that language has to interact in the same ways with all cognitive processes. Yet, this is seemingly taken for granted, especially within dual-process approaches. -/- On my view, it is a central requirement for a theory of the role of language in cognition to explain how language might have effects, at once, on and within various parts of cognition. In Chapter 4, I explore how this framework can modify how we think about some experiments in psychology, specifically in research on categorization. My idea is that language, once it evolved, changed how some cognitive capacities worked and interacted with each other, but did so in more than one or two ways. Cognitive systems are changed in very different ways—sometimes the transformation is very subtle, such as our way of forming categories by using how similar objects are, while other times it is deep and changes the very way the system works.

Andrews argues for a pluralistic folk psychology that employs different kinds of practices and different kinds of cognitive tools (including personality trait attribution, stereotype activation, inductive reasoning about past behavior, and ...

Does scientific psychology have a legitimate role to play in the philosophy of language? For example, is it methodologically permissible for philosophers of language to rely upon evidence from neurological development, experiments about processing, brain scans, clinical case histories, longitudinal studies, questionnaires, etc.? If so, why? These two questions are the focus of this survey. I address them in two stages. It may seem obvious that the science of psychology is relevant. I thus begin by introducing arguments against relevance, to (...) motivate the discussion. I will urge that these arguments ultimately fail, and that the appearance of relevance should be taken at face value. Next, I introduce positive arguments for relevance, with examples. To foreshadow the main conclusion, the methods and results of contemporary cognitive psychology are relevant because there are non-obvious connections, both constitutive and contingent, between language and human psychology.

RÉSUMÉ: Le point de vue de Davidson sur les concepts de croyance et de signification implicites dans nos pratiques d’attribution de croyance et de signification peut à bon droit être mis à l’épreuve par une élucidation de ses rapports avec la psychologie empirique. Mais une telle mise à l’épreuve n’a de valeur que si elle confronte d’abord l’id’e reçue voulant que sa position a peu ou pas de liens avec l’etude empirique du développement cognitif. Je défends ici une approche du (...) point de vue de Davidson qui montre clairement en quoi une vaste gamme de découvertes empiriques en psychologie du développement -- souvent considérées comme non pertinentes, voire comme incompatibles, avec son enquête conceptuelle -- est en fait fort pertinente et en harmonie avec lui.

We clarify some points previously made by Andrews, and defend the claim that Davidson's account of belief can be and is challenged by the existence of some people with autism. We argue that both Bouma and Andrews (Philosophical Psychology, 15) blurred the subtle distinctions between the psychological concepts of theory of mind and joint attention and the Davidsonian concepts of interpretation and triangulation. And we accept that appeal to control group studies is not the appropriate place to look for an (...) individual who can speak but who has significant problems with interpretation. In this paper we argue that by turning to the clinical literature we can more readily find such a challenge to Davidson's account. (shrink)

When we ask the question whether animals have their own folk psychology, we’re asking whether any other species has a commonsense conception of psychological phenomenon. Different versions of this question have been discussed over the past 25 years, but no clear answer has emerged. Perhaps one reason for this lack of progress is that we don’t clearly understand the question. I defend a two-fold view of folk psychology that takes as central the capacity to engage in some folk psychological practices (...) (e.g. predicting, explaining, coordinating, justifying, etc.) and the capacity to see another as minded. Given this account, I argue that chimpanzees, as intentional agents who engage in folk psychological practices and have some understanding of others as minded agents, are folk psychologists. -/- .

When we think about what others believe and want, we are usually affected by what we know about their attitudes. If I’m aware that another person believes something, I have an opportunity to agree or disagree with it. If I think that another person wants something, I can endorse or disapprove of her desire. The importance of such reactions to attributed beliefs and desires has thus far been overlooked in philosophy of mind where the focus has been on explanatory and (...) predictive roles of attitude attribution. The primary goal of this thesis is to fill this lacuna and to articulate the indispensability of such reactions – agreement/disagreement and endorsement/disapproval – for social cognition. In the process of doing it I also show how these initial reactions ground certain further possible responses in intersubjective communication: manipulation, negotiation or adoption of attributed attitudes. The second aim of this thesis is to explicate what is it about belief and desire attributions that makes the responses I’ve described possible. Because one can agree or disagree both with beliefs and assertions and endorse or disapprove both desires and requests, I argue that we should understand belief attributions in terms of assertions and desire attributions in terms of requests. When we think what someone believes and wants, we treat her as a conversation partner because her attitudes call for the same responses as speech acts do, even if she hasn’t made any explicit assertion or request herself. In short, beliefs and desires have communicative significance. Given such significance, we can also see what one needs to take into consideration when attributing these attitudes to another. My answer in the thesis is that belief and desire attributions have to be grounded in facts about the behaviour and well-being of attributees and that these facts also constitute the nature of beliefs and desires.

The view (held, e.g., by Davidson) that the having of beliefs and desires presupposes the having of reflective capacities is sometimes supported by appealing to the idea that the concept of belief is a concept of a mental state which involves a normative aspect: beliefs can be “successful” or “unsuccessful” from the perspective of their possessors, and sometimes discarded in light of their “failure.” This naturally invites the idea that believers must be capable of reflecting on their beliefs. Desires presuppose (...) reflectivity if only in virtue of their essential linkage with beliefs. This paper suggests a sense in which mental states—including those of non-reflective creatures—can have such a normative aspect. On this suggestion, the intelligible relations that obtain between cognitive states and conative states open the door for the possibility of normativity without reflectivity. Due to these relations, a creature's beliefs can be successful or unsuccessful from its own perspective even without its conceiving of them. (shrink)

This paper surveys and evaluates the answers that philosophers and animal researchers have given to two questions. Do animals have thoughts? If so, are their thoughts conceptual? Along the way, special attention is paid to distinguish debates of substance from mere battles over terminology, and to isolate fruitful areas for future research.

This paper reviews some of the arguments put forward by some psychologists in which they come to the conclusion that autistic individuals suffer from mindblindness, and also looks at one particular implication these sorts of individuals pose for Donald Davidson’s theory of radical interpretation. It has been claimed that a particular manifestation of mindblindness in autistic people serves as a counter example to claims Davidson has made about the relation between belief and intention in linguistic competence.

The relation between conceptual analysis and empirical observations when ascribing or denying concepts and beliefs to non-human animals is not straightforward. In order to reflect on this relation, I focus on two theoretical proposals and one empirical case, the three of which are permanently discussed and considered in the literature on animal cognition. First, I review briefly Davidson’s arguments for denying thought to non-linguistic animals. Second, I review Allen’s criteria for ascribing concepts to creatures capable of correcting their discriminatory powers (...) by taking into account their previous errors. Allen affirms that this is an empirical proposal which offers good reasons, but not necessary or sufficient conditions, for concept attribution. Against Allen, I argue that his important proposal is not an empirical, but a conceptual one. Third, I resort to vervet monkeys to show that Allen’s criteria, and not Davidson’s, are very relevant for ascribing first-order and denying second-order beliefs to this species and thus make sense of the idea of animal cognition.

Donald Davidson argues in "Thought and Talk" that all speakers must be interpreters of other speakers: linguistic competence requires the possession of intentional concepts and the ability to attribute intentional states to other people. Kristin Andrews (in Philosophical Psychology, 15) has argued that empirical evidence about autism undermines this theoretical claim, for some individuals with autism lack the requisite "theory of mind" skills to be able to interpret, yet are competent speakers. In this paper, Davidson is defended on the grounds (...) that the high-functioning autistic individuals in question have a more robust theory of mind than has been acknowledged, and that this is sufficient for them to be interpreters of other speakers. It is argued, further, that Davidson's theory would remain intact even if one or more autistic speakers lacking a theory of mind were to exist, as he makes conceptual claims about thought and language that are not vulnerable to empirical counterexamples.

The contemporary development of naturalism has left us has in many ways ‘objectified’ our world, giving us a material world of laws and causes, that is in some ways strangely distant from our notions of ‘self.’ We might be said to possess a very strong ‘sense of self,’ and looking at our friends and neighbors, we get the impression that everybody holds similarly strong feelings. We live in a world populated by lumps of matter, but also rational agents, intricate persons, (...) and perhaps most importantly, centered around a self. How can naturalism, without invoking the Cartesian ego, account for our deeply held conceptions of ‘self’ and ‘person?’ To answer some of these troubling questions, we need to need to examine the origins of these important yet mysterious concepts. We would do well to take a survey of the environment and mechanism by which the concepts of ‘self’ and ‘person’ come into being and persist. I am speaking, of course, of the brain. Understanding the brain, especially in the context of its adaptation to the world through the process of natural selection, may be the key to figuring out where these concepts come from as well as what sort of structure they possess.
