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

The functionalist conception of mental properties, together with their multiple realizability, is often taken to entail their irreducibility. It might seem that the only way to revise that judgement is to weaken the requirements traditionally imposed on reduction. However, Jaegwon Kim has recently argued that we should, on the contrary, strengthen those requirements, and construe reduction as what I propose to call “logical reduction”, a model of reduction inspired by emergentism. Moreover, Kim claims that what he calls “functional reduction” allows one to reduce (at least some) mental properties by these new standards. I argue against both theses. First, I present a counterexample to the emergentist model of reduction: The model judges irreducible certain properties which are clearly reducible. Second, I contestthat functional reduction as construed by Kim satisfies the emergentist constraints. Functional reduction implies, over and above a functional definition of the reduced property, the indication of its realizers. But the latter information corresponding to the discovery of a (local) bridge law, is empirical and not purely logical

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

It has been argued that most truths about macroscopic states of affairs are entailed by a (hypothetical) complete descriptionPof the world in microscopic terms. In principle, micro-reductive explanations of non-microphysical truths could be constructeda priori.Against this claim, I show that reductive explanation requires knowledge about the phenomena to be reduced which cannot bea prioriextracted from microphysical information alone. Such reductions proceed in two steps: a “reductionR0” (“role-occupant”) establishes that a macroproperty M plays a certain causal role (specified in macro-terms), while a “reductionMM” (“micro-macro”) establishes that some microproperty gives rise toM.

Many predicates are dispositional. Some show this by a suffix like "-ible", -uble", or "-able": sugar is soluble in water, gasoline is flammable. Others have no such suffix and don't wear their dispositionality on their sleeves. Yet part of what it is to be solid is to be disposed to resist deformation, and part of what it is to be red is to appear red to normal human observers in normal lighting conditions. However, there is no agreement as to whether dispositional predicates may be given a realist interpretation. For many authors, propositions containing them are made true by states of affairs (or facts) containing categorical, rather than dispositional properties. Many also claim that the states of affairs that make true attributions of dispositions to macroscopic objects are microscopic states of affairs concerning their parts. For example, what makes a vase fragile is the microscopic structure of its molecular constituents, which is what makes the vase break when it falls. Against these claims, I will argue that what makes a dispositional predicate apply to an object, whether macroscopic or microscopic, whether in common sense or science, is the object's having what I will call a powerful property. If the object is macroscopic, it is another matter whether the property is microreducible. My reasons for supposing that these powerful properties exist are those for postulating theoretical properties generally: they unify existing explanations and suggest new ones.

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.

To explain phenomenon R by showing how mechanism M yields output R each time it is triggered by circumstances C, is to give a causal explanation of R. This paper analyses what mechanistic analysis can contribute to our understanding of causation in general and of downward causation in particular. It is first shown, against Glennan, that the concept of causation cannot be reduced to that of mechanism. Second it is shown, against Craver and Bechtel, that mechanistic explanation allows us to make sense of causal processes that cut across levels, either in bottom-up direction where a change in a part of a system causes a change in the whole, or in downward direction where a change at the level of the system causes a change at the level of its parts. I suggest construing a decision's influence on molecules in muscle cells as a global constraint. Microscopic laws determine the detailed evolution of muscle cells and glucose molecules, but this evolution is constrained by the fact that it must be compatible with the action caused by the decision.

The key idea of the interventionist account of causation is that a variable A causes a variable B if and only if B would change if A were manipulated in the appropriate way. This paper raises two problems for Woodward's (2003) version of interventionism. The first is that the conditions it imposes are not sufficient for causation, because these conditions are also satisfied by non-causal relations of nomological dependence expressed in association laws. Such laws ground a relation of mutual manipulability that is incompatible with the asymmetry of causation. Several ways of defending the interventionist account are examined and found unsatisfying. The second problem is that it often seems to be impossible, in a model that contains variables linked by an association law, to satisfy the conditions imposed on interventions on such variables. Various ways to solve this second problem, most importantly the analysis of manipulability in terms of difference making, are examined. Given that none solves the problem, I conclude that the interventionist conditions are neither sufficient nor necessary for causation. It is suggested that they provide an analysis of nomological dependence, which may be supplemented with the notion of a causal process to yield an analysis of causation
