Two conceptual frameworks – in terms of phase space and in terms of structural equations – are sketched, in which downward causal influence of higher-level features on lower-level features is possible. The “Exclusion” principle, which is a crucial premise of the argument against the possibility of downward causation, is false in models constructed within both frameworks. Both frameworks can be supplemented with conceptual tools that make it possible to explain why downward causal influence is not only conceivable and compatible with the “Closure” principle, but also why it is often relevant to causally explain facts in terms of downward causal influence. It is briefly shown that the analysis of downward causation in the two frameworks complements Bennett’s analysis of overdetermination, the analysis does not entail the failure of the “Closure” principle and it does not require the postulate of synchronic downward 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.

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 ..

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

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

In E.J. Lowe's ontology, 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” 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.

Can laws of nature be universal regularities and nevertheless have exceptions? Several answers to this question, in particular the thesis that there are no laws outside of fundamental physics, are examined and rejected. It is suggested that one can account for exceptions by conceiving of laws as strictly universal determination relations between (instances of) properties. When a natural property is instantiated, laws of nature give rise to other, typically dispositional properties. In exceptional situations, such properties manifest themselves either in an unusual way or not at all.

Causation is analysed in terms of transference of amounts of conserved quantities between events. Such amounts are tropes. However, causal explanations are directly made true, not by transmission relations but by relations of causal responsibility, of a fact Fc about the cause event c for a fact Ge about the effect event e. Causal responsibility is analysed in terms of causation between events c and e and a law of nature holding between the properties F and G. This account overcomes many objections against other process theories, as well as against accounts in terms of counterfactual dependency and conditional probabilities
