I propose an amendment of Lewis's counterfactual analysis of causation, designed to overcome some difficulties concerning redundant causation.

In this paper I present a metaphysically minimalist but theoretically strong version of fact causation, in which the causal relata constitute a full Boolean algebra, mirroring the entailment relation of the sentences that express them. I suggest a generalization of the notion of multiple realizability of causes in terms of specificity of facts, and employ this in an interpretation of what goes on in cases of apparently redundant causation.

The main line of Lewis's account of causation is in terms of chains of counterfactual dependence. According to his original account, a causal chain is a sequence of two or more events, with counterfactual dependence at each step; and one event is a cause of another if there is a causal chain from one to the other. But some awkward cases involving redundant causation lead him to introduce the notion of quasi-dependence. Laurie Paul has suggested a way (...) of dealing with one important class of these cases in terms of dependence proper. I shall suggest a different way of dealing with this class of cases; I shall also suggest that it is possible to deal with other awkward cases too in terms of dependence proper. (shrink)

Causation is at once familiar and mysterious. Neither common sense nor extensive philosophical debate has led us to anything like agreement on the correct analysis of the concept of causation, or an account of the metaphysical nature of the causal relation. Causation: A User's Guide cuts a clear path through this confusing but vital landscape. L. A. Paul and Ned Hall guide the reader through the most important philosophical treatments of causation, negotiating the terrain by taking (...) a set of examples as landmarks. They clarify the central themes of the debate about causation, and cover questions about causation involving omissions or absences, preemption and other species of redundant causation, and the possibility that causation is not transitive. Along the way, Paul and Hall examine several contemporary proposals for analyzing the nature of causation and assess their merits and overall methodological cogency.The book is designed to be of value both to trained specialists and those coming to the problem of causation for the first time. It provides the reader with a broad and sophisticated view of the metaphysics of the causal relation. (shrink)

In recent years, a number of philosophers have attempted to fix paradoxes of the counterfactual account of causation by making causation contrastive. In this framework, causation is understood to be not a two-place relationship between a cause and an effect but a three or four-place relationship between a cause, an effect and a contrast on the side of the cause, the effect or both. I argue that contrasting helps resolving certain paradoxes only if an account of admissibility (...) of the chosen set of contrasts is given. I show by means of numerous examples that it is contextual features that determine admissibility. This way, context becomes part of the semantics of causation. I finally argue that once contextualised, explicit contrasting is redundant: causation is therefore a three-place relationship between a cause, an effect and a context. (shrink)

The paper builds on the basically Humean idea that A is a cause of B iff A and B both occur, A precedes B, and A raises the metaphysical or epistemic status of B given the obtaining circumstances. It argues that in pursuit of a theory of deterministic causation this ‘status raising’ is best explicated not in regularity or counterfactual terms, but in terms of ranking functions. On this basis, it constructs a rigorous theory of deterministic causation that (...) successfully deals with cases of overdetermination and pre-emption. It finally indicates how the account's profound epistemic relativization induced by ranking theory can be undone.

Nancy Cartwright begins her recent book, Hunting Causes and Using Them, by noting that while a few years ago real causal claims were in dispute, nowadays “causality is back, and with a vengeance.” In the case of the social sciences, Keith Morrison writes that “Social science asks ‘why?’. Detecting causality or its corollary—prediction—is the jewel in the crown of social science research.” With respect to the health sciences, Judea Pearl writes that the “research questions that motivate most studies in the (...) health sciences are causal in nature.” However, not all data used by people interested in making causal claims come from experiments that use random assignment to control and treatment groups. Indeed, much research in the social and health science depends on non-experimental, observational data. Thus, one of the most important problems in the social and health sciences concerns making warranted causal claims using non-experimental, observational data; viz., “Can observational data be used to make etiological inferences leading to warranted causal claims?” This paper examines one method of warranting causal claims that is especially widespread in epidemiology and the health sciences generally—the use of causal criteria. It is argued that cases of complex causation generally, and redundant causation—both causal overdetermination and causal preemption—specifically, undermine the use of such criteria to warrant causal claims.

I argue that the Exclusion Argument against mental causation is self‐defeating and should be rejected by everyone. A new version of the Argument—the ‘Micro Exclusion Argument’—does not undermine itself, but, I argue, we should reject that argument in light of the rejection of microphysical closure defended earlier in the book. And, among other things, I present an argument against free will, an argument that presupposes incompatibilism. I then show that those who believe in non‐redundant mental causation of (...) the sort I defend in Ch. 4 can resist that argument. And so, I suggest, incompatibilists who believe in free will should embrace my most controversial claims about mental causation. (shrink)

David Lewis’s latest theory of causation defines the causal link in terms of the relation of influence between events. It turns out, however, that one event’s influencing another is neither a necessary nor sufficient condition for its being a cause of that event. In the article one particular case of causality without influence is presented and developed. This case not only serves as a counterexample to Lewis’s influence theory, but also threatens earlier counterfactual analyses of causation by admitting (...) a particularly troublesome type of preemption. The conclusion of the article is that Lewis’s influence method of solving the preemption problem fails, and that we need a new and fresh approach to the cases of redundant causation if we want to hold on to the counterfactual analysis of causation.

A key test of any philosophical account of the mind is its treatment of mental causation. Proponents of the token-identity theory point to its strengths in both “demystifying” mental causation — by identifying mental causes with the physical causal mechanisms underlying bodily movements — and in avoiding commitment to dubious forms of causal overdetermination. I argue against this account of mental causation, pointing out that it mistakenly identifies actions with bodily movements. I suggest instead treating action explanations (...) as explanations of redundant causalities in behavior, and the mental causes cited in such explanations as structural causes. (shrink)

The aim of this dissertation is to provide an analysis of central concepts in philosophy of science from the perspective of current molecular and developmental research. Each chapter explores the ways in which particular phenomena or discoveries in molecular biology influences our philosophical understanding of the nature of scientific knowledge. The introductory prologue draws some general connections between the various threads, which revolve around two central themes: causation and explanation. Chapter Two identifies a particular type of causal relation which (...) is widespread across the sciences, but cannot be straightforwardly accommodated by extant accounts of causation and causal explanation. Chapter Three explores how the form of redundant causality identified in the previous chapter plays an important role in causal explanation, by making the effect stable and robust. Chapter Four offers a novel perspective on the debate over biological reductionism by distinguishing between different paradigms of molecular explanation. Chapter Five provides a philosophical analysis of the so-called "Developmental Synthesis" of evolutionary and developmental biology, and suggests a general account of scientific unification grounded in the notion of explanatory relevance. Chapter Six offers an account of dispositional properties inspired by mechanisms of gene regulation, according to which dispositions are not properties of entities, but properties that describe the behavior of abstract idealized models. Finally, Chapter Seven scrutinizes the concept of the molecular ecosystem, a metaphor frequently employed by biologists to describe cellular interactions, but seldom articulated in detail. (shrink)

In many biological experiments, due to gene-redundancy or distributed backup mechanisms, there are no visible effects on the functionality of the organism when a gene is knocked out or down. In such cases there is apparently no counterfactual dependence between the gene and the phenotype in question, although intuitively the gene is causally relevant. Due to relativity of causal relations to causal models, we suggest that such cases can be handled by changing the resolution of the causal model that represents (...) the system. By decreasing the resolution of our causal model, counterfactual dependencies can be established at a higher level of abstraction. By increasing the resolution, stepwise causal dependencies of the right kind can serve as a sufficient condition for causal relevance. Finally, we discuss how introducing a temporal dimension in causal models can account for causation in cases of non-modular systems dynamics. (shrink)

My dissertation concerns the long-standing mind-body problem in a contemporary context. I investigate whether a content property of a mental state can be causally efficacious in bringing about behavior. I argue that general objections against the causal efficacy of content are not warranted. I then propose my own account of the causal efficacy of content. ;In Chapter 1, I examine the claim that the supervenience thesis renders mental causation incompatible with underlying physical causation. I argue that if we (...) understand the supervenience thesis and the concept of causation probabilistically, it turns out that the causal efficacy of the mental is compatible with that of the physical. ;In Chapter 2, I claim that given the compatibility claim established in the previous chapter, the computational theory of the mind can be understood as a causal hypothesis. I examine this hypothesis in details and Fodor's "narrow content" proposal. I argue that Fodor's proposal has a serious problem. ;In Chapter 3, I discuss individualism which implies that content is not a psychologically relevant property. I argue that individualism is in conflict with legitimate scientific practices and that there is no reason not to individuate psychological properties in terms of diachronic, causal relations. ;In Chapter 4, I investigate the screening-off argument that since content is unnecessary and redundant for the genesis of behavior, content cannot be causally efficacious. I argue that the argument is not valid. I also critically examine three accounts of the causal efficacy of content and claim that they fall short of conferring causal efficacy to content. ;In Chapter 5, I propose an account of causal efficacy which is consistent with the requirement of causal transaction via local, physical mechanism. My account is based on the notion of causal connection which is, in turn, understood as a category of token probabilistic causal significances. According to my account, content can be causally efficacious in bringing about behavior. I conclude that reasons qua reasons have causal have causal efficacy. (shrink)

The overdetermination problem has long been raised as a challenge to nonreductive physicalism. Nonreductive physicalists have, in various ways, tried to resolve the problem through appeal to counterfactuals. This essay does two things. First, it takes up the question whether counterfactuals can yield an appropriate notion of causal redundancy and argues for a negative answer. Second, it examines how this issue bears on the mental causation debate. In particular, it considers the argument that the overdetermination problem simply does not (...) arise on a dependency conception of causation and shows why this idea, though initially appealing, does not address the real problem. As the essay shows, the idea derives its spurious plausibility from the fact that the dependency conception cannot even make sense of our pretheoretic idea of causal redundancy. The essay concludes by briefly discussing a possible picture of mental causation that suggests itself in light of these results. (shrink)

This article takes stock of the regularity theory of causation. It considers three challenges to the theory: the problem of joint effects, the problems of redundant causation, and omission‐involving causation. The former is often cited as a special, and especially challenging, problem for regularity theories. But the force of this problem has been greatly overstated. The threat to regularity theories instead comes from the latter two.

We raise and attempt to resolve the charge that the third noble truth of the core Buddhist teachings is redundant. If the second noble truth asserts a causal relation between craving and suffering, and if James Woodward’s interventionist account of causation is correct, we argue that these premises are sufficient to entail the difference-making described by the third noble truth. Thus, the third noble truth would be superfluous insofar as it merely makes explicit what must be the case, (...) according to a plausible theory of causation, if the second noble truth is true. Having raised the possibility that the third noble truth is redundant, we consider five possible responses to the charge, the last of which we endorse. Even if the redundancy charge is found not to stick, we believe an investigation into why this is so highlights features of the third noble truth that might be suppressed under standard glosses of its meaning.

This paper argues that so-called “trumping preemption” is in fact overdetermination or early preemption, and is thus not a distinctive form of redundant causation. I draw a novel lesson from cases thought to be trumping: that the boundary between preemption and overdetermination should be reconsidered.

Mental causation is a problem and not just a problem for the nonphysicalist. One of the many lessons learned from Jaegwon Kim’s writings in the philosophy of mind is that mental causation is a problem for the nonreductive physicalist as well. A central component of the common sense picture we have of ourselves as persons is that our beliefs and desires causally explain our actions. But the completeness of the “brain sciences” threatens this picture. If all of our (...) actions are causally explained by neurophysiological events occurring in our brains, what causal role is left for our reasons and motives? It would seem that these brain events do all the causal work there is to do, thus robbing the mental of its efficacy altogether or else making it a merely superfluous or redundant causal factor. This essay presents a systematic treatment of this exclusion dilemma from the perspective of a nonreductive physicalist. I argue that both horns of this dilemma can be avoided if we ground mental causation in counterfactual dependence between distinct events and understand the mind-body relation as event realization. Although in the final analysis our actions are overdetermined by their mental and neurophysiological antecedents, this overdetermination is entirely unproblematic. (shrink)

permits a sound and rigorously definable notion of ‘originating cause’ or causa causans—a type of transition event—of an outcome event. Mackie has famously suggested that causes form a family of ‘inus’ conditions, where an inus condition is ‘an insufficient but non-redundant part of an unnecessary but sufficient condition’. In this essay the needed concepts of BST theory are developed in detail, and it is then proved that the causae causantes of a given outcome event have exactly the structure of (...) a set of Mackie inus conditions. The proof requires the assumption that there is no EPR-like ‘funny business’. This seems enough to constitute a theory of ‘causation’ in at least one of its many senses.

Here is a simple counterexample to David Lewis’s causal influence account of causation, one that is especially illuminating due to its connection to what Lewis himself writes: it is a variant of his trumping example.

Whatever you think of Bertrand Russell’s famous claim that the ‘law of causality’ is (at least as of 1912) redundant in the ‘advanced sciences’, it is nonethele.

Setting aside all exclusion-style worries about the redundancy of postulating additional, non-physical mental causes for effects that can already be explained in purely physical terms, dualists who treat mental properties as supervening on physical properties still face a further problem: in cases of mental-to-mental causation, they cannot avoid positing an implausibly coincidental coordination in the timing of the distinct causal processes terminating, respectively, in the mental effect and its physical base. I argue that this problem arises regardless of whether (...) one treats the mental cause as causing both the mental effect and its physical base, or whether one treats the latter as having instead been caused by some physical state, and that the problem also does not depend on which theory of causation one adopts. A third option of treating the mental cause and its physical base as producing the mental effect and its physical base by a single causal process that they both contribute to is found to come up short as well.

A regularity theory of causation analyses type-level causation in terms of Boolean difference-making. The essential ingredient that helps this theoretical framework overcome the problems of Hume’s and Mill’s classical accounts is a principle of non-redundancy: only Boolean dependency structures from which no elements can be eliminated track causation. The first part of this paper argues that the recent regularity theoretic literature has not consistently implemented this principle, for it disregarded an important type of redundancies: structural redundancies. Moreover, (...) it is shown that a regularity theory needs to be underwritten by a hitherto neglected metaphysical background assumption stipulating that the world's causal makeup is not ambiguous. Against that background, the second part then develops a new regularity theory that does justice to all types of redundancies and, thereby, provides the first all-inclusive notion of Boolean difference-making.

In this essay, I defend a mind-body dualism, according to which human minds are immaterial substances that exercise non-redundant causal powers over bodies, against the notorious problem of psychophysical causation. I explicate and reply to three formulations of the problem: (i) the claim that, on dualism, psychophysical causation is inconsistent with physical causal closure, (ii) the claim that psychophysical causation on the dualist view is intolerably mysterious, and (iii) Jaegwon Kim’s claim that dualism fails to account (...) for causal pairings. Ultimately, I conclude that these objections fail and that dualist interactionism is no more problematic or mysterious than physical causation. (shrink)

Sydney Shoemaker has attempted to save mental causation by a new account of realization. As Brian McLaughlin argues convincingly, the account has to face two major problems. First, realization does not guarantee entailment. So even if mental properties are realized by physical properties, they need not be entailed by them. This is the first, rather general metaphysical problem. A second problem, which relates more directly to mental causation is that Shoemaker must appeal to some kind of proportionality as (...) a constraint on causation in order to avoid redundant mental causation. I argue that, in addition, a “piling problem” arises, since causal powers seem to be bestowed twice. Then, I try to sketch an alternative view of the relation between causal powers and properties—a reductionist view—which fares better on some accounts. But it may have to face another and, perhaps, serious problem, the “problem of the natural unity of properties”. Finally, I will pose a question about the relation between causal powers and causation. (shrink)

The article discusses the limitations of psycho-physical parallellism and the implications of a pscycho-physical interaction paradigm considering the notion Downward Causation. The focus is on the notion of levels in nature and their interrelations, and it argues that the notion of rule-based systems should be considered a subcategory of rule-generating systems partly based on redundancy functions rather than rules.

This thesis in an invistigation into the concept of "harm" and its moral relevance. A common view is that an analysis of harm should include a counterfactual condition: an act harms a person iff it makes that person worse off. A common objection to the moral relevance of harm, thus understood, is the non-identity problem. -/- This thesis criticises the counterfactual condition, argues for an alternative analysis and that harm plays two important normative roles. -/- The main ground for rejecting (...) the counterfactual condition is that it has unacceptable consequences in cases of overdetermination and pre-emption. Several modifications to the condition are considered but all fail to solve this problem. -/- According to the alternative analysis to do harm is to perform an act which is responsible for the obtaining of a state of affairs which makes a person’s life go worse. It is argued that should be understood in terms of counterfactual dependence. This claim is defended against counterexamples based on redundant causation. An analysis of is also provided using the notion of a well-being function. It is argued that by introducing this notion it is possible to analyse contributive value without making use of counterfactual comparisons and to solve the non-identity problem. -/- Regarding the normative importance of harm, a popular intuition is that there is an asymmetry in our obligations to future people: that a person would have a life worth living were she to exist is not a reason in favour of creating that person while that a person would have a life not worth living is a reason against creating that person. It is argued that the asymmetry can be classified as a moral option grounded in autonomy. Central to this defence is the suggestion that harm is relevant to understanding autonomy. Autonomy involves partly the freedom to pursue one’s own aims as long as one does no harm. (shrink)

This chapter considers the arguments for and against reductionism and then considers its main rival: emergence. A large part of the reductionist program is generally considered a failure. Philosophers of science have been chipping away at reductionist claims for a couple of decades now. Philosopher Jaegwon Kim has been a central figure in matters of reduction, supervenience, and emergence. He presents three related puzzles for the antireductionist: causal redundancy; downward causation and causal drainage. According to the author, reduction and (...) emergence have earned a place in science and the philosophy of science. The chapter finally presents the diagnosis of the controversy between reductionists and their foes and then briefly considers some theological ramifications. (shrink)

This essay enriches causal models capturing the propagation of prejudice, bias, and other aggregative social mechanisms, negative or positive. These explananda include the reinforcement of economic inequality, “mob-like” behavior, peer pressure, and the establishment of social norms. The stage is set by introducing various forms of redundant causation and discussing some difficulties with mainstream preemption. Next the main proposal extends current representations of aggregative social mechanisms in two respects. First, it is more nuanced, as it identifies three distinct (...) kinds of inferences: relevance of causes to effects, degree of redundancy of an effect, and the influence that causes exert on other causes. Second, it offers a quantitative—as opposed to merely qualitative—distinction between the causal contribution of preempting and preempted causes. (shrink)

Causal overdetermination occupies an uncomfortable place within all the major theories of causation. A natural solution to the problems it gives rise to would be to resolve overdetermination into preemption or joint causation. However, such a solution would seem to lead to individuate events in a fragile manner. The issue of such modal fragility is addressed and it is argued that events designated as effects are always fragile in a natural way and the putative problems of adopting modal (...) fragility can be resolved. It is also studied whether causal overdetermination could work in a setting where the overdetermining causes occur in different levels of reality. Typically postulated higher-level causes are shown to contradict the definitional features of overdetermination. There is thus no reasonable role for causal overdetermination and the notion should be abandoned. (shrink)

When evaluating theories of causation, intuitions should not play a decisive role, not even intuitions in flawlessly-designed thought experiments. Indeed, no coherent theory of causation can respect the typical person’s intuitions in redundancy (pre-emption) thought experiments, without disrespecting their intuitions in threat-and-saviour (switching/short-circuit) thought experiments. I provide a deductively sound argument for these claims. Amazingly, this argument assumes absolutely nothing about the nature of causation. I also provide a second argument, whose conclusion is even stronger: the typical (...) person’s causal intuitions are thoroughly unreliable. This argument proceeds by raising the neglected question: in what respects is information about intermediate and enabling variables relevant to reliable causal judgment? (shrink)

Regularity theories of causation are guided by the idea that causes are collectively sufficient for their effects. Following Mackie [1974], that idea is typically refined to distinguish collections that include redundant members from those that do not. Causes must be collectively sufficient for their effects without redundancy. While Mackie was surely right that the regularity theory must distinguish collections that are in some sense minimally sufficient for an effect from those that include unnecessary hangers-on, I believe that redundancy (...) is the wrong mark of that distinction. I propose a way to develop the regularity theory without it. Instead of distinguishing minimal from mere sufficiency in terms of redundancy, we should look to the influence that events have in the world. Causes, so construed, must have just enough collective influence to ensure that an effect occurs. I argue that such an account provides a uniform solution to the problem of epiphenomena and to a pair of related problems that aris.. (shrink)

When is a cause of a cause of an effect also a cause of that effect? The right answer is either Sometimes or Always . In favour of Always , transitivity is considered by some to be necessary for distinguishing causes from redundant non-causal events. Moreover transitivity may be motivated by an interest in an unselective notion of causation, untroubled by principles of invidious discrimination. And causal relations appear to add up like transitive relations, so that the obtaining (...) of the overarching relation is not independent of the obtaining of the intermediaries. On the other hand, in favour of Sometimes , often we seem not to treat events that are very spatiotemporally remote from an effect as its causes, even when connected to the effect in question by a chain of counterfactual or chance-raising dependence. Moreover cases of double prevention provide counterexamples to causal transitivity even over short chains. According to the argument of this paper, causation is non-transitive. Transitizing causation provides no viable account of causal redundancy. An unselective approach to causation may motivate resisting the distance counterexamples to transitivity, but it does not help with double prevention, and even makes it more intractable. The strongest point in favour of transitivity is the adding up of causal relations, and this is the point that extant non-transitizing analyses have not adequately addressed. I propose a necessary condition on causation that explains the adding up phenomenon. In doing so it also provides a unifying explanation of distance and double prevention counterexamples to transitivity. (shrink)

Objects and Persons presents an original theory about what kinds of things exist. Trenton Merricks argues that there are no non-living inanimate macrophysical objects -- no statues or rocks or chairs or stars -- because they would have no causal role over and above the causal role of their microphysical parts. Humans do exist: we have non-redundant causal powers. Along the way, Merricks has interesting things to say about mental causation, free will, and various philosophical puzzles. Anyone working (...) in metaphysics will enjoy this lucid and provocative book. (shrink)

Causation appears to present us with an interpretative difficulty. While arguably a redundant relation given fundamental physics, it is nevertheless apparently pragmatically indispensable. This chapter revisits certain arguments made previously by the author for these claims with the benefit of hindsight, starting with the role of causal models in the human sciences, and attempting to explain why it is not possible to straightforwardly ground such models in fundamental physics. This suggests that further constraints, going beyond physics, are needed (...) to legitimate such models. These supplementary constraints could be reified, but that would seem to conflict with the completeness of physics. A response is to emphasize the practical role of causal talk, and the author suggests that a fictionalist approach might be worth exploring. After clarifying fictionalism as a general approach, they carry out in some detail the project of clarifying what a fictionalist attitude to causation would involve. (shrink)

In response to counterexamples involving late preemption, David Lewis (1986) revised his original (1973) counterfactual analysis of causation to include the notion of quasi-dependence. Jonardon Ganeri, Paul Noordhof and Murali Ramachandran (1998) argue that their ‘PCA*-analysis’ of causation solves the problem of late preemption and is superior to Lewis’s analysis. I show that neither quasi-dependence nor the PCA*-analysis solves the problem of late preemption.

Backtracking influence is influence that zigzags in time. For example, backtracking influence exists when an event E_1 makes an event E_2 more likely by way of a nomic connection that goes from E_1 back in time to an event C and then forward in time to E_2. I contend that in our local region of spacetime, at least, backtracking influence is redundant in the sense that any existing backtracking influence exerted by E_1 on E_2 is equivalent to E_1's temporally (...) direct influence on E_2. I prove the redundancy of backtracking influence using several plausible physical principles without assuming any fundamental temporal or causal asymmetry. This explanation can play a prominent role in an account of why causation appears to be objectively asymmetric regardless of whether the fundamental laws are symmetric. (shrink)

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment. Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

Following Chalmers, I take the most promising response to the meta-problem to be a realizationist one on which (roughly) consciousness plays a role in realizing the processes that explain why we think that there is a hard problem of consciousness. I favour an interactionist dualist version of realizationism on which experiences are non-physical states that non-redundantly cause problem judgments. This view is subject to the challenges of specifying laws that would enable experiences to cause problem judgments and of explaining why (...) it's not a lucky coincidence that experiences' causal and rational powers converge on problem judgments. I propose a strategy for solving the meta-problem and meeting these challenges. According to it, a fundamental teleological law operates on normative features of experiences in ways that bias experiences towards causing effects that they rationalize, including problem judgments. I conclude by applying the strategy to other luck-avoidance challenges. (shrink)

I show that Leibniz’s account of divine concurrence is constrained in a surprising way by his commitment to the Principle of Sufficient Reason, where a sufficient reason for the existence of an entity or a state of affairs is understood to be the totality of requisites for its existence. I argue first that Leibniz endorses, in both his early and later metaphysics, the ‘totality of requisites’ conception of sufficient reason. I then show that this conception gives rise to a distinctive (...) and underappreciated logical redundancy problem. Finally, I show that the logical redundancy problem can be side-stepped if we attribute to Leibniz the view that the states of any created substance are caused by God in a single act. On this view, God’s concurrence with creaturely activity is irreducibly plural: the natural effects or states of any created substance are brought about together, as a collective. I show that there are both philosophical and textual grounds for attributing such a view to Leibniz. (shrink)

Frank Jackson and Philip Pettit have defended a non-reductive account of causal relevance known as the ‘program explanation account’. Allegedly, irreducible mental properties can be causally relevant in virtue of figuring in non-redundant program explanations which convey information not conveyed by explanations in terms of the physical properties that actually do the ‘causal work’. I argue that none of the possible ways to spell out the intuitively plausible idea of a program explanation serves its purpose, viz., defends non-reductive physicalism (...) against Jaegwon Kim’s Causal Exclusion Argument according to which non-reductive physicalism is committed to epiphenomenalism because irreducible mental properties are ‘screened off’ from causal relevance by their physical realizers. Jackson and Pettit’s most promising explication of a program explanation appeals to the idea of invariance of effect under variation of realization , but I show that invariance of effect under variation of realization is neither necessary nor sufficient for causal relevance.

Is theistic evolution (TE) a philosophically tenable position? Leidenhag argues in his article “The Blurred Line between Theistic Evolution and Intelligent Design” that it is not, since it, Leidenhag claims, espouses a view of divine action that he labels “natural divine causation” (NDC), which makes God explanatory redundant. That is, in so far as TE does not invoke God as an additional cause alongside natural causes, it is untenable. Theistic evolutionists should therefore “reject NDC and affirm a more (...) robust notion of divine agency.” However, this will, Leidenhag claims, have the effect that theistic evolutionists “will move their position significantly closer to Intelligent Design,” and so the line between TE and intelligent design is (or ought to be?) blurred. If successful, the criticism by Leidenhag would be bad news for theists who want to take science seriously and good news for those scientistic atheists according to whom there simply is no scientifically respectable way of combining theism and modern natural science in an overarching worldview. So, is TE stuck between a rock (of redundancy) and a hard place (of pseudo‐science)? No, at least not due to the criticism offered by Leidenhag—but maybe religious naturalism is? (shrink)

Over the last decade, attention has crawled from out of the shadows into the philosophical limelight with several important books and widely read articles. Carolyn Dicey Jennings has been a key player in the attention revolution, actively publishing in the area and promoting awareness. This book was much anticipated by insiders and does not disappoint. It is in no way redundant with respect to other recent monographs, covering both a different range of material and developing novel positions throughout. The (...) book might have been called The Attending Self, since Jennings defines attention as mental prioritization controlled by the self. This invocation of the self is among her central innovations, and may prove to be the main source of controversy. I will highlight points of contention here, but want to emphasize at the outset that the book is essential reading for anyone interested in attention. Jennings also contributes to a range of other debates, which will help a broader audience appreciate the importance this topic.After a brief introduction, Jennings provides “a philosophical landscape” of attention (chap. 2), tracing the concept through history. This is an invaluable achievement that will be welcomed by both newcomers and veterans. Jennings exhibits enormous breadth, covering areas that contemporary philosophers of mind tend to neglect: medieval philosophy, Buddhist thought, and phenomenology, to name a few. We also get perspectives on attention from core figures in the Western canon, such as Descartes, Locke, and Kant, as well as thinkers who gave the topic a more political inflection: Mary Wollstonecraft and W. E. B. DuBois. Jennings surveys contemporary literature as well, locating recent work in these older lineages. Some authors get more treatment later in the book (e.g., William James and Wayne Wu). Overall, Jennings provides the best overview of this history I have seen. She proves that attention is not a new topic, but one with deep roots and one that can inform current debates; Jennings draws on these roots throughout. I would love to see a companion piece surveying scientific theories, including “gain control” and “biased competition,” which get little airtime in the book. Some recent philosophical theories are under-explored as well, including Chris Mole’s concept of cognitive unison (Jennings discusses other aspects of his view), Carlos Montemayor and Harry Haladjian’s exploration of attention’s diversity (we get a touch of this), and my own proposal that attention is a gateway to working memory (not mentioned here). That said, no extant survey is more complete.Chapter 3 begins with the empirical claim that attention is regulated by slow brainwaves, and then takes up two issues. The first is mental causation. Endorsing moderate emergentism, Jennings argues that slow brain waves are causally efficacious even though they are not reducible to lower-level processes. (The metaphysics and neuroscience are presented accessibly, aided by three appendixes.) Second, Jennings argues that these slow brain waves indicate that attention is controlled by the self. As someone who was never moved by the mental causation problem—I don’t think overdetermination threatens efficacy—I would have welcomed more development of this second issue. For one thing, in linking attention to subjective control, Jennings eschews the idea that there can be purely “bottom-up” attention driven by stimulus features alone. This goes against the orthodoxy in attention science, and makes it hard for her to accommodate phenomena such as “pop-out,” or the commonsense idea that attention can be “captured” by a sudden flash or loud sound. For another thing, I wanted to hear more on why Jennings relates slow brain waves to the self. Does this include the slow waves that occur during deep sleep? Is there even such a thing as the self? Is there one self or many? How do slow brain waves reflect our interests, projects, values, self-conceptions, autobiographical narratives, or social identities? Does the social self invoked by Wollstonecraft and DuBois gain a foothold here? The whole chapter campaigns against metaphysical reductionism, but arrives at a perspective on the self that will strike some readers as highly reductive.In the fourth chapter, Jennings sheds further light on her conjecture that attention involves the self by advancing the thesis that attention endows sensory information with meaning. On the face of it, this may sound implausible. Object recognition, reading, and many other meaning-involving processes can take place outside of attention and outside of consciousness. But Jennings has a richer notion of “meaning” in mind. She develops the idea of “subject unity,” which is imposition of structure on perception that reflects the interests of the perceiving subject. This, she claims, is what brings perception into the space of reasons. Along the way, she has interesting observations about binding, feature integration, and demonstrative reference. The material is highly original, and Jennings’s postulation of interest-based perceptual organization is compelling. At the same time, one might wonder whether interests are really relegated to the ambit of attentional control. Consider the cocktail party effect, wherein one’s own name captures attention. This implies a preattentive filter that reflects our interests. Emotionally charged words, facial expressions, and dangerous objects also work this way, and social biases can operate preattentively as well. If these reflect our interests, then meaning may arise outside attention.Jennings’s fifth chapter explores the relationship between attention and consciousness. Some authors have argued that attention is necessary and sufficient for consciousness. Jennings focuses primarily on the necessity claim. She does not systematically review the empirical literature here, but she addresses some of the key findings, and effectively rebuts studies that allege to find consciousness outside attention. She does not rest her case there, however. Instead, she identifies a new class of examples that purport to establish the possibility of consciousness without attention. Her central example she calls “conscious entrainment,” which is what we experience when engaged in habitual or skilled activities. Other possible examples touched on in the chapter include hypervigilance in individuals with attention deficit hyperactivity disorder (ADHD), passive movie watching, dreaming, and “attentional neglect.” These states all involve intense focus, Jennings admits, but not attention. To some readers this may sound contradictory. Isn’t focus a kind of attention? Don’t these states of absorption involve stimulus selection and enhancement of relevant features, suppression of distractors, and other hallmarks of attention? Jennings says none of this is tantamount to attention. Recall that she thinks attention is controlled by the self. In these cases, we are invited to imagine that the self takes a passive role: control is either ceded to the world (movie watching) or to previously mastered routines (skills and habits). Thus, Jennings’s claim that there is no attention in these cases hangs on her contentious thesis that attention requires a controlling self. One might also push back by arguing that, in some of Jennings’s allegedly selfless examples, the self remains involved. Skilled activities and hypervigilance, for example, can reflect personal interests.Skills and hypervigilance get more airtime in chapter 6. There, Jennings turns to questions of responsibility—a neglected topic in attention research. The chapter begins with a manslaughter trial in which the teenage plaintiff was given a light sentence because the judge evidently believed that the teen’s ADHD compromised his ability to control his actions. The example may be a bit triggering for people who have a personal relationship with this diagnosis, but, putting that aside, Jennings uses it to introduce the important concept of attention-based control. With reduced control, Jennings argues, comes reduced responsibility. I am inclined to see ADHD as involving dysregulation of attention (difficulty disengaging and dividing attention, for example) rather than diminished attention, but that can still be characterized as an issue with control of attention; therefore ADHD still illustrates Jennings’s point that there is a link between responsibility and control of attention. This, it turns out, is only half of her story. Having argued for this link, one might expect Jennings to follow Wayne Wu, who contends that attention is necessary for action, and hence for responsibility. She does not. Instead, she says argues that responsibility can also arise in cases of “strategic automaticity.” This brings us back to skills. When skills are deployed, action is governed by learned pairings between stimuli and responses. The choice to exercise a skill requires attention, so attention is needed for being a responsible agent, but once a skill kicks in, attention is no longer required, and one can be held responsible for actions performed skillfully—thus attention is not required for responsibility tout court. Jennings addresses an opposing view (defended by Wu, Ellen Fridland, and Barbara Montero), according to which skills involve “automatic attention” rather than no attention. Jennings worries that this move will collapse the distinction between attention and other kinds of selection and filtering that occur throughout the nervous system, including the retina. She says that the attentional interpretation of skilled action is at odds with the lack of top-down reweighing of sensory inputs, regulated by lateral frontal cortex. These objections to automatic attention warrant response. My own view is that attention involves broadcasting to working memory, so retinal filtering is ruled out. Jennings’s insistence on top-down reweighing will not move those who believe attention can be purely bottom-up. For all that, I side with Jennings in wanting to allow for responsibility without attentional control. I think we can be responsible for implicit biases, for example. I also think attentional control is insufficient for responsibility, as when we act under duress.Jennings offers fresh perspective on the nature of attention, and its role in meaningful perception, consciousness, action, and responsibility. Each chapter can be read separately, but they hang together well, and each reflects her thesis that attention is essentially linked to the self. Though I am skeptical of that strong claim, we would do well to follow Jennings in regarding attention as interest-laden interface between mind and world. I look forward to a sequel in which attention is related to richer conceptions of identity, and where the political consequences of this link are actively explored. Meanwhile, one can hardly fault Jennings for covering too little. She tackles a remarkable range of topics, from metaphysics to ethics. Her arguments throughout demand response, repay careful study, and propel the field forward. (shrink)

Recently, there has been an increased interest in employing model-based definitions of actual causation in legal inquiry. The formal precision of such approaches promises to be an improvement over more traditional approaches. Yet model-based approaches are viable only if suitable models of legal cases can be provided, and providing such models is sometimes difficult. I argue that causal-model-based definitions benefit legal inquiry in an indirect way. They make explicit the causal assumptions that need to be made plausible to defend (...) a particular claim of actual causation. My argument concerns the analysis of legal cases involving a combination of double prevention and causal redundancy. I show that discussions among legal theorists about such cases sometimes suffer from ambiguous assumptions about the causal structure. My account illustrates that causal models can act as a heuristic tool for clarifying such assumptions, and that causal models provide a framework for more accurate analyses of legal cases involving complex causal structure.

I argue that we human organisms—though composite—are not mere overdeterminers. We cause, by way of having conscious mental properties, some effects that our constituent atoms do not cause. Because mental causation makes us causally non‐redundant, we are not eliminated by the overdetermination argument of Ch. 3.

The acceptance of causal closure has had a profoundly limiting effect on the philosophical treatment of sui generis mental causation in recent decades. Philosophical treatments of special divine action have been likewise hampered by a widespread commitment to closure. If fundamental reality is as closure tells us it is, then nonphysical minds—human and divine— are either causally impotent or redundant. In this paper, I reject this limitation as baseless. Specifically, I will show how Hempel’s dilemma poses a far (...) greater challenge when applied to a causal closure principle than it did to the task of defining physicalism. Reponses to the dilemma can be used to disambiguate closure, but not without significant cost. In light of Hempel’s dilemma, there is no conception of closure that can do all of the following: rule out sui generis mental causation, have a reasonable chance of being true, and avoid problematic circularity. At the end of the day, I maintain that closure, properly understood, is, or ought to be, just one methodological stance among many. If this is correct, it is a stance that a theist can freely reject.

A central argument for non-reductive accounts of group agency is that complex social entities are capable of exerting causal influence independently of and superseding the causal efficacy of the individuals constituting them. A prominent counter is that non-reductionists run into an insuperable dilemma between identity and redundancy – with identity undermining independent higher-level efficacy and redundancy leading to overdetermination or exclusion. This paper argues that critics of non-reductionism can manage with a simpler and more persuasive reductio strategy called mapping: allow (...) that group agents are causally efficacious in their own right and chart how their causal efficacy is carried out; how it relates to the causal efficacy of individual determiners; how it connects to the causal relevance of background structural factors. The focus exclusively on whether groups are or are not causally efficacious black-boxes implementation, while close attention to how causation is wired increases the visibility of individualist arguments and countenances structure-oriented explanations.

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment.Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

This paper provides epistemological support for one of Hume’s numerous critiques of the teleological arguments for God’s existence. Hume explores the following question: can we explain the observed harmony of the universe without appealing to the work of an intelligent creator? The answer, presented through the character of Philo, appears to be positive. I will try to defend this position. Following Hume’s theory of space, and exploring the relation between ideas of the whole and relation, I will show the universe (...) can be seen as finite space with definite numbers of parts which are spatially and causally interconnected. Because all changes occur on the basis of Hume’s principle of causation, we can say the harmony of the universe is established and maintained precisely because of the changes happening on the basis of causation. If this is the case, the role of the intelligent creator appears to be redundant. (shrink)
