With the aim of giving a naturalistic foundation to the notion of mental representation, Fred Dretske (1981;1988) has put forward and developed the idea that the relation between a representation and its intentional content is grounded on an informational relation. In this explanatory model, mental representations are conceived of as states of organisms which a learning process has selected to play a functional role: a necessary condition for fulfilling this role is that the organism or some proper part of it (presumably situated in the brain) is a natural indicator of the occurrence of a determinate type of event in the environment of the organism (or in the organism but outside of the proper part serving as the indicator). A state of the organism is a natural indicator of a type of event if and only if it carries information about the occurrence of that type of event. Jerry Fodor (1987) has devised and followed another strategy which consists in considering the relation between a mental representation and its intentional object as a relation of lawful, or nomic, dependence. A representational state of an organism has an objective content in virtue of the existence of a relation of nomic dependence between this state - presumably a property of the brain of the organism - and some objective property in the world. This dependence also creates a regular correlation between the occurrences of representational states of a certain type and the states of affairs whose type is their representational content. Both approaches encounter indeterminacy problems: for each, there exist situations in which the explanatory model chosen - information flow or nomic dependence - does not succeed in selecting, purely on the basis of the constraints characteristic of that model, one out of several potential contents for a given representational state. In such cases, that state is related to more than one type of events in accordance with the informational or nomic constraints imposed by those theories. In what follows, I examine an attempt by Pierre Jacob (1997) to solve two problems of indeterminacy threatening the informational theory of mental representation. According to Jacob, one of these problems can be solved with the help of the distinction between the source which is the target of the information and the channel over which the information is transmitted, whereas the solution to the other problem requires the introduction of the concept of function. I shall begin with a consideration of the distinction, with respect to a situation of information transmission, between the source and the channel. I argue that both the source and the channel, and thus the information transmitted, depend not only on the external situation which characterises the source, the channel and the receiving organism, but also on the previous knowledge and the informational needs of the receiver. I then try to show that this relativity of information undermines the solution Jacob proposes to one of the problems of indeterminacy of representational content. Finally, I examine the possibility considered by Dretske and Jacob to solve this 'problem of the reference class' due to the mentioned relativity of information, by grounding the flow of information on lawful dependence instead of statistical dependence. I shall propose two arguments showing first that these two groundings are not equivalent and second that nomic dependence is inappropriate as a grounding for information flow. I conclude by suggesting that the problem of the reference class can be solved within the framework of the informational approach, on the condition of enriching it with functional considerations

Esfeld's new book is a powerful and well-argued statement for an original position in the metaphysics of science. In Esfeld's view, rational reflection on relativity theory and quantum theory leads to a metaphysical conception of reality as built on powerful structures: first, the fundamental building blocks of reality are structures rather than properties of space-time points or of matter localized at such points; second, these structures are not categorical or inert but inherently powerful and sources of relations that hold necessarily

I analyse Rueger’s application of Kim’s model of functional reduction to the relation between the thermal conductivities of metal bars at macroscopic and atomic scales. 1) I show that it is a misunderstanding to accuse the functional reduction model of not accounting for the fact that there are causal powers at the micro-level which have no equivalent at the macro-level. The model not only allows but requires that the causal powers by virtue of which a functional predicate is defined, are only a subset of the causal powers of the properties filling the functional specification. 2) The fact that the micro-equation does not converge to the macro-equation in general but only under the constraint of a “solvability condition” does not show that reduction is impossible, as Rueger claims, but only that reduction requires inter-level constraints. 3) Rueger tries to analyse inter-level reduction with the conceptual means of intra-level reduction. This threatens the coherence of his analysis, given that it makes no sense to ascribe macroproperties such as thermal conductivity to entities at the atomic level. Ignoring the distinction between theses two senses of “reduction” is especially confusing because they have opposite directions: in intra-level reduction, the more detailed account reduces to the less detailed one, whereas in inter-level reduction, the less detailed theory is reduced to the more detailed one. 4) Finally I criticize Rueger’s way of using Wimsatt’s criteria for emergence in terms of non-aggregativity, to construct a concept of synchronic emergence. It is wrong to require, over and above non-aggregativity, irreducibility as a criterion for emergence.

I propose a realist theory of laws formulated in terms of tropes that avoids both the problems of the "best-systems-analysis" and the "inference problem" of realism of universals. I analyze the concept of an exceptional situation, characterized as a situation in which a particular object satisfies the antecedent but not the consequent of the regularity associated with a law, without thereby falsifying that law. To take this possibility into account, the properties linked by a law must be conceived as dispositional and not necessarily manifest

Causation can be reduced to transmission in the following way: Two events c and e are linked as cause and effect iff there is a conserved quantity P which is exemplified in both events and of which an amount Q is transferred from c to e. This conception permits to overcome difficulties faced by earlier versions of the transference theory and by "process theories" of causation, such as Salmon's and Dowe's. In particular, it can explain the asymmetry of causality without relying on the asymmetry of time, and the difference between causal and pseudo-processes

I propose an argument for the thesis that laws of nature are necessary in the sense of holding in all worlds sharing the properties of the actual world, on the basis of a principle I propose to call the Causal Criterion of Reality . The CCR says: for an entity to be real it is necessary and sufficient that it is capable to make a difference to causal interactions. The crucial idea here is that the capacity to interact causally - or to contribute to determining causal interactions - is not only the ultimate metaphysical ground for the existence of an entity, but it also provides a criterion for determining the nature of that entity, i.e. its properties. The alternative is to conceive of laws of nature as contingent: they could be different from what they are like in the actual world, where that possibility is understood to be metaphysical, not only epistemic. For the sake of this paper, I shall accept Armstrong's thesis that laws of nature are relations between universals. I also follow Armstrong in the view that both the existence and the properties of particulars are metaphysically independent of the existence and identity of other particular. However, what is controversial and what I shall challenge is his thesis that universals are like particulars in the following respect: according to Armstrong, each universal is a logically distinct entity whose existence and identity is independent of the existence and identity of other universals. My aim in this paper is to show that the identity of a universal is entirely determined by its lawful relations to other universals. The crucial premise I use is the thesis that the CCR is a universal criterion, which applies both to particulars and universals. From the thesis that the identity of a universal is exclusively determined by laws, it follows that laws are necessary in the sense that they cannot differ without the universals they link also being different. This creates a difficulty for those authors who, as Armstrong, accept the CCR but nevertheless defend the view that laws are contingent

Contemporary analytic philosophy is in the midst of a vigorous debate on the nature of causation. Each of the main proposals discussed in this chapter faces important problems: the deductive-nomological model, the counterfactual theory, the manipulability theory, the probabilistic theory and the transference theory. After having explored possible solutions to these problems, I conclude that one version of the transference approach is most promising. However, as I show in the last section, it is necessary to supplement this transference approach with the notion of lawful dependency. This gives rise to the notion of causal responsibility

The papers collected in this volume explore some of the powers and limitations of the concept of mechanism for the scientific understanding of cognitive systems, and aim at bringing together some of the most recent developments in the philosophical understanding of the relation of cognition to neuroscience. Earlier versions of most papers have been presented at a workshop held in Paris on June 19th, 2006, which was organized by Institut Jean Nicod and supported by RESCIF (R seau des sciences cognitives en Ile-de-France)

This paper tries to remove some obstacles standing in the way of considering mental properties as both genuine natural kinds and causally efficacious rather than epiphenomena. As the case of temperature shows, it is not justified to conclude from a property being multiply realizable to it being irreducible. Yet Kim's argument to the effect that if a property is multiply realizable with a heterogeneous reduction base then it cannot be a natural kind and possesses only derivative “epiphenomenal” causal efficacy is not conclusive either. The fact that temperature is, but jade is not, a natural kind cannot be established by comparing the heterogeneity of their respective reduction bases, but rather by the fact that the former is and the latter is not embedded in laws of nature

L. A. Paul and Ned Hall’s book makes an original and important contribution to the philosophical debate on causation. Their aim is not to construct a theory of causation but “to sketch a map” of the “landscape” (1) constituted by a rich set of problem cases and various theories of causation devised to account for them.Chapter 1 presents the scope and aim of the book, justifies the method of evaluating theories of causation by exploring whether they are refuted by counterexamples, and provides an overview of the rest of the book.Chapter 2 justifies the choice of problems and solutions considered in the book. Several assumptions are made from the beginning. Causation is taken to be a relation among particular events rather than types of events. A “reductionist outlook” is adopted, according to which facts about what causes what are determined by (1) facts about what happens and (2) fundamental laws. These assumptions provide the background for a “minimal sufficiency account” of causation ..

La philosophie des sciences de l'empirisme logique avait discredite la causalite comme etant un concept du sens commun irremediablement vague et confus, pour lui substituer le concept d'explication scientifique. Cependant, dans nombre de theories contemporaines, notamment en philosophie de l'esprit et du langage, le concept de causalite continue a jouer un role de premier plan. Ce livre montre qu'il est possible de concevoir la causalite d'une maniere compatible avec des connaissances scientifiques contemporaines. La relation causale fondamentale a lieu entre evenements en fonction de la transmission d'une quantite determinee d'une grandeur conservee; mais ce qui rend vraie une explication causale, ce n'est pas seulement une relation causale entre deux evenements, mais une relation de responsabilite causale. Le concept de loi de la nature qui intervient dans cette analyse s'avere fructueux non seulement dans le cadre de la causalite, mais aussi pour l'eclairage qu'il permet d'apporter a la philosophie des sciences.

The idea that causation can be reduced to transmission of an amount of some conserved quantity between events is spelled out and defended against important objections. Transmission is understood as a symmetrical relation of copresence in two distinct events. The actual asymmetry of causality has its origin in the asymmetrical character of certain irreversible physical processes and then spreads through the causal net. This conception is compatible with the possibility of backwards causation and with a causal theory of time. Genidentity, the persistence of concrete objects, can be given an explanation in causal terms. The transmission theory is shown to escape difficulties faced by two important alternative theories of causation: Salmon's (1984) Mark Transmission Theory and Dowe's (1992a) Conserved Quantities Theory.

Humans have only finite discriminatory capacities. This simple fact seems to be incompatible with the existence of appearances. As many authors have noted, the hypothesis that appearances exist seems to be refuted by reductio: Let A, B, C be three uniformly coloured surfaces presented to a subject in optimal viewing conditions, such that A, B, and C resemble one another perfectly except with respect to their colours. Their colours differ slightly in the following way: the difference between A and B and the difference between B and C are below the discrimination threshold, but the difference between A and C is above this threshold. According to an intuitive construal of what an appearance is, given that A and B appear (to the subject) identical in colour, A and B have the same (colour1) appearance P1; likewise, B and C have the same appearance P2. B's appearance is both P1 and P2. This seems to imply that P1=P2. But then, A and C also have the same appearance, which contradicts the hypothesis that A and C are discriminable. If A and C are discriminable with respect to their colour, they do not have the same appearance with respect to colour. The paradox arising from such a series of judgments of sameness or difference between pairs of coloured surfaces seems to belong to the class of sorites paradoxes. I will show that there is a way to construe colours and their appearances in a way that does not fall prey to the reduction just sketched

The search for a nomological account of what determines the content of concepts as they are represented in cognitive systems, is an important part of the general project of explaining intentional phenomena in naturalistic terms. I examine Fodor's "Theory of Content" and criticize his strategy of combining constraints in nomological terms with contraints in terms of actual causal relations. The paper focuses on the problem of the indeterminacy of the content of natural kind concepts. A concept like water can pick out either a phenomenological property or a scientific one. Moreover, even on the assumption that the latter is shown to be most adequate, a given sample will still come out as falling into different natural kinds, according to the taxomomy of each particular science of which it constitutes an object. Both chemistry and physics contain concepts which are scientific counterparts of the common sense concept water, yet their extensions differ. As a criterion for determining the most relevant science for a given concept, I suggest to ask which science is most specific for the typical interactions of the subject possessing the concept, with her environment. The use of this criterion also permits one to show that a nomological theory is not necessarily verificationist, contrary to what has been claimed by Fodor and Boghossian
