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

During the last decades there has been a remarkable renewal of interest in theories of causation which is linked to the decline of the orthodoxy of the Logical empiricist school. A number of alternatives to the traditional covering-law account have been proposed. I shall defend a version of an approach that has been undeservedly neglected: the Transference Theory of causation. Accounts of this type elaborate the intuition that there is a material link between the cause and the effect, consisting of something transmitted between them

In the first part of this paper, I argue against the view that laws of nature are contingent, by attacking a necessary condition for its truth within the framework of a conception of laws as relations between universals. I try to show that there is no independent reason to think that universals have an essence independent of their nomological properties. However, such a non-qualitative essence is required to make sense of the idea that different laws link the same universals in different possible worlds. In the second part, I give a positive argument for the necessity of at least some laws of nature, by showing with the example of a paradigmatic law of association that it consists in an internal relation between two universals which are determinables of the same class of determinates, where this relation is essential to both. Furthermore, I show that the necessity of laws of association could be accommodated within David Lewis' Humean metaphysics, but that it is incompatible with David Armstrong's combinatorialism.

In E.J. Lowe's ontology, (individual) objects are property-bearers which 1) have identity and 2) are countable. This makes it possible to become or cease to be an object, by beginning or ceasing to fulfil one of these conditions. But the possibility of switching fundamental ontological categories should be excluded. Furthermore, Lowe does not show that “quasi-individuals” (which are not countable) can exist. I argue against Lowe that kinds cannot be property-bearers in a more genuine sense than properties, that they are not absolutely countable, whether conceived according to science or common sense, and that they are dependent on individual objects

Kim attribue aux émergentistes un modèle de « réduction logique » dans lequel la prédiction ou l’explication d’une occurrence de la propriété réduite ne requiert, outre des informations sur le niveau réducteur, que des principes logiques et mathématiques. Sur la base de cette interprétation, je conteste deux thèses de Kim. La première concerne la légitimité du modèle émergentiste de réduction. J’essaie de montrer, à l’aide de l’exemple de l’addition des masses, que l’adoption de la réduction logique rendrait irréductibles certaines propriétés qui sont clairement réductibles. La deuxième est la thèse selon laquelle la réduction fonctionnelle correspond aux exigences émergentistes sur la réduction. Telle que Kim la caractérise, la réduction fonctionnelle comporte, outre une définition fonctionnelle de la propriété à réduire, l’indication des propriétés réalisatrices. Or cette information, qui correspond à la découverte d’une loi de correspondance , est empirique et non seulement logique.I read Kim as attributing to the emergentists a model of “logical reduction” in which the prediction or explanation of an occurrence of the reduced property requires, beyond information on the reducing level, only logical and mathematical principles. On the basis of this interpretation, I argue against two theses of Kim's. The first concerns the legitimacy of the emergentist model of reduction. I try to show by the example of the addition of masses that according to logical reduction certain properties which are clearly reducible come out as irreducible. The second is the thesis that functional reduction as construed by Kim satisfies the emergentist constraints on reduction. Functional reduction implies, over and above a functional definition of the reduced property, the indication of its realizers. But this information corresponding to the discovery of a bridge law is empirical and not only logical

The paper defends the view that events are the basic relata of causation, against arguments based on linguistic analysis to the effect that only facts can play that role. According to those arguments, causal contexts let the meaning of the expressions embedded in them shift: even expressions possessing the linguistic form that usually designates an event take a factual meaning.However, defending events as fundamental relata of causation turns out to be possible only by attributing a – different – causal role to facts as well. The role of facts in causation is characterized as «causal responsibility». This relation, and its connection to causation between events, is clarified by way of the analysis of different inference patterns between causal statements of the two sorts: statements linking events and statements linking facts
