The question to be discussed is whether the distinction between the conceptual and the nonconceptual is best understood as pertaining primarily to intentional contents or to intentional states or attitudes. Some authors have suggested that it must be understood in the second way, in order to make the claim that experiences are nonconceptual compatible with the idea that one can also believe what one experiences. I argue that there is no need to do so, and that a conceptual content can be understood as being simply one which is composed of concepts, without compromising this intuitive view of the relation between beliefs and experiences.

Dans la section 1, j’explique pourquoi une conception Dummet-tienne du réalisme n’a de pertinence que dans certains cas particuliers. Dans la section 2, j’indique qu’il est raisonnable de penser que Crispin Wright soutient que la vérité de certains jugements dépend de notre capacité de la connaître (si et) seulement si leur vérité consiste dans le fait qu’ils sont superassertables. Dans la section 3, je souligne qu’insister, avec Dummett et Wright, sur la connaissabilité, nous empêche de voir qu’il y a d’autres formes légitimes de réalisme. Je propose une réfutation de la thèse attribuée à Wright dans la section 2, ce qui m’amène à suggérer que c’est une erreur de penser que la question du réalisme concerne essentiellement la nature de la vérité.

Depuis 1967, Donald Davidson defend l'idée qu'une théorie de la signification pour une langue naturelle doit prendre la forme d'une théorie tarskienne de la vérité. Je me propose ici d'exposer les grandes lignes de l a conception davidsonienne de la sémantique des langues naturelles et de chercher à préciser en quel sens une theorie tarskienne de la vérité pour une langue L constitue, selon Davidson, une théorié de la signification pour L. Je ferai pour cela abstraction des obstacles qu'il pourrait y avoir à la réalisation du programme de Davidson.

I clarify in what sense one might want to claim that thought or language are public. I distinguish among four forms that each of these claims might take, and two general ways of establishing them that might be contemplated. The first infers the public character of thought from the public character of language, and the second infers the latter from the former. I show that neither of these stategies seems to be able to dispense with the claim that thought and language are interdependent, and that the second strategy raises more difficulties than the first. I then examine the reasoning by which Davidson means to establish that thought depends on language. I claim that this reasoning is not conclusive, and that it can be adapted in such a way as to establish a version of the thesis that thought is public which does not presuppose that language is public, and a version of the thesis that language is public which does not imply that thought depends on language. I conclude with the suggestion that despite appearances to the contrary Davidson's doctrine is defensible only if it implies at least the conceivability of intentional systems that would lack language altogether.

ABSTRACT: I offer a refutation of the standard argument according to which we have no doxastic obligation because we do not have the kind of voluntary control over our beliefs required for having obligations. I then propose an interpretation of the distinction between epistemic and practical reasons for belief which can be generalised to other attitudes such as intention, and seems to imply that mental acts such as judgements and decisions never count as intentional actions, and that these two sorts of reasons are incommensurable

The view that in radical interpretation, the interpreter should aim at optimizing the rationality of agents is defended. A distinction and a parallel is drawn between linguistic interpretation and psychological interpretation. Both can be taken to be governed, in part, and in somewhat different ways, by a principle of rationality. Such approaches have been criticised on the ground that they make it impossible for a speaker or an agent to have wildly irrational or false beliefs. It is argued that the so-called principle of simulation isn't a serious altemative, and that the counter-intuitiveness of the optimization-based approaches has been exaggerated.

The theory of radical interpretation, as based on the principle of charity, sets a priori limits on the possibility that different agents have different beliefs, and on the possibility that one has false beliefs. David Papineau put forward a teleological approach to intentional states which, he claims, doesn’t have these unacceptable consequences. Having distinguished half a dozen of different forms that the problem of radical interpretation might take, I show that Papineau’s approach is not radically different from those based on the principle of charity. Finally, I suggest that the consequences of the principle of charity with respect to the problems of error and divergence are in fact both unavoidable and acceptable.

The purpose of this paper is to offer an account of what an agent's being rational to do or think something might amount to, which doesn't reduce to saying that it consists in this agent's doing or thinking something that is rational for him. In the first section, I call attention to the fact that such a distinction between agent rationality and action or belief rationality is widely admitted, I reject the idea that it could be interpreted as a distinction between the rationality of tokens and the rationality of types, and I suggest one natural way in which a notion of objective agent rationality could be informally characterized in terms of action or belief rationality. But this first, rough, characterization depends on further uses of the notion of rationality which I try to make sense of in the second section, at least in a preliminary way. The burden of this second section is then to determine whether the intuition behind the informal proposal introduced in the first can be substantiated, i.e., whether a substantial and coherent notion of agent rationality can be worked out, and at what cost. In the concluding section, I try to "deflate" some of the worries that could be raised by the account of agent rationality I end up with.

I try to clarify the ways in which one would seek to hold that language and/or thought are public. For each of these theses, I distinguish four forms in which they can be framed, and two ways of establishing them. The first will try to make the publicity of thought follow from that of language; the second will try to make the publicity of language follow from that of thought. I show that none of these strategies can do without the thesis that language and thought are interdependent, and that even while admitting this thesis, the second strategy presents more difficulties than the first.

Dans quelle mesure les caractéristiques fondamentales des êtres humains, telles que leur capacité de penser, de raisonner, de vouloir et de communiquer, peuvent-elles être complètement expliquées à l'aide des seules ressources des sciences naturelles? En s'appuyant sur l'analyse rigoureuse de quelques-uns des travaux les plus significatifs de la philosophie de l'esprit, en particulier ceux de R. Millikan, F. Dretske, W. Quine et D. Davidson, Daniel Laurier révèle les limites d'un tel programme de naturalisation de l'esprit et soutient qu'il n'y a pas de position stable entre le naturalisme radical et ce qu'il faut bien appeler le surnaturalisme. Ce livre s'adresse principalement aux philosophes professionnels et aux chercheurs et étudiants en sciences humaines qui s'intéressent à l'épistémologie et aux fondements philosophiques des sciences cognitives.
