Experimental investigation of mechanisms seems to make use of causal relations that cut across levels of composition. In bottom-up experiments, one intervenes on parts of a mechanism to observe the whole; in top-down experiments, one intervenes on the whole mechanism to observe certain parts of it. It is controversial whether such experiments really make use of interlevel causation, and indeed whether the idea of causation across levels is even conceptually coherent. Craver and Bechtel have suggested that interlevel causal claims can (...) be analysed in a causal and a non-causal component. I accept this idea but argue that their account should be modified so as to account of cases of apparent downward causation. First, constitution must be distinguished from identity; second, the analysis of downward causation requires the concept of a partial constraint. An analysis along these lines shows that the possibility of downward causation is not refuted by Kim's argument according to which it is incompatible with the completeness of physics. (shrink)

The 'completeness of physics' is the key premise in the causal argument for physicalism. Standard formulations of it fail to rule out emergent downwards causation. I argue that it must do this if it is tare in a valid causal argument for physicalism. Drawing on the notion of conferring causal power, I formulate a suitable principle, 'strong completeness'. I investigate the metaphysical implications of distinguishing this principle from emergent downwards causation, and I argue that categoricalist accounts of properties are better (...) equipped to sustain the distinction than dispositional essentialist accounts. Finally, I argue that the additional evidence needed for strong completeness renders the causal argument otiose for any properties amenable to scientific reduction. (shrink)

This paper examines Jaegwon Kim's Supervenience Argument (SA) against nonreductive physicalism, concentrating on Kim's response to two of the most important objections against the SA: First, the Overdetermination Argument, according to which Kim has no convincing argument against the possibility that mental causation might be a case of genuine or systematic overdetermination; second, the Generalization Argument, according to which the SA would entail that causation at any level gives way to causation at the next lower level, thereby leading to an (...) untenable all-encompassing epiphenomenalism. It is argued that as of yet, Kim has failed to develop a coherent overall position, since various moves he makes in response to these criticisms are strangely at odds with other parts of his philosophical position.

Most readers will agree with the starting assumptions of Klee that contemporary science and philosophy assume a primarily micro-deterministic view of nature–and that this has long been the case, or was at least until the 1970s. Defending a strict micro-determinism, Klee argues that concepts of emergence that seemingly are opposed to micro-determinist doctrine can be shown, on analysis, to be ultimately consistent with a thoroughgoing philosophy of micro-determinism. An exception is made, however, in the case of my own view, labeled (...) “direct macro-determinism,” which he describes as “ultimately more troublesome” but then disposes of as being based on “simplistic analogies” and “metaphors” and “too weak to be conclusive.”. (shrink)

Emergence requires that the ultimate physical micro-entities have “micro-latent” causal powers, which manifest themselves only when the entities are combined in ways that are “emergence-engendering,” in addition to the “micro-manifest” powers that account for their behavior in other circumstances. Subjects of emergent properties will have emergent micro-structural properties, specified partly in terms of these micro-latent powers, each of which will be determined by a micro-structural property specified only in terms of the micro-manifest powers of the constituents and the way they (...) are related. If the determiner and the determined properties are distinct, this determination is the basis of the supervenience of emergent properties on non-emergent physical properties. If not, emergence does not involve such supervenience. Either way, there is no problem with diachronic downward causation. (shrink)

The aim of this paper is to show that Kim’s ‚supervenience argument’ is at best inconclusive and so fails to provide an adequate challenge to nonreductive physicalism. I shall argue, first, that Kim’s argument rests on assumptions that the nonreductive physicalist is entitled to regard as question-begging; second, that even if those assumptions are granted, it is not clear that irreducible mental causes fail to␣satisfy them; and, third, that since the argument has the overall structure of a reductio, which of (...) its various premises one performs the reductio on remains open to debate in an interesting way. I shall finally suggest that the issue of reductive vs. nonreductive physicalism is best contested not in the arena of mental causation but in that in which the issues pertaining to theory and property reduction are currently being debated.

A debate has been raging in the philosophy of mind for at least the past two decades. It concerns whether the mental can make a causal difference to the world. Suppose that I am reading the newspaper and it is getting dark. I switch on the light, and continue with my reading. One explanation of why my switching on of the light occurred is that a desiring with a particular content (that I continue reading), a noticing with a particular content (...) (that it is getting dark), and a believing with a particular content (that by switching on the light I could continue reading) occurred in me, and these events caused my switching on of the light. This explanation works by citing the intentional contents of mental phenomena as causes of that action. It is because the intentional causes have the contents that they do, and because those contents play a causal role in bringing about my action, that my action is causally explained. (shrink)

NRP is a family of views differing by how they understand “reduction” and “physicalism.” Following Kim I understand the non-reduction as holding that some events and properties are distinct from any physical events and properties. A necessary condition for physicalism is that mental properties, events, and laws supervene on physical ones. Kim allows various understandings of “supervenience” but I think that physicalism requires at least the claim that any minimal physical duplicate of the actual world is a duplicate simpliciter. Some (...) complications aside this means that true mental propositions, e.g. Jaegwon is thinking about sailing, are metaphysically entailed by true physical propositions. Kim says that supervenience is too weak to capture the root idea of physicalism that mental property instantiations depend on physical property instantiations so he adds that the mental depends on the physical. One way in which this dependance might be spelled out is that mental properties are higher order functional properties whose instantiations are realized by instantiations of physical properties. An event is an instantiation of a property by an individual and a time. A mental event is the instantiation of a mental property. Not every predicate expresses a genuine property. Kim further suggests that properties are individuated, at least partly, by nomological and causal relations. For physicalism to have content something must be said about the difficult issue of characterizing the physical. Kim’s view seems to be that the micro-physical properties of ideal physics are physical. He also counts as physical properties that are conjunctions and aggregates of micro-physical properties and higher level properties defined over lower-level physical properties.. Since these latter two classes of properties supervene on the micro-properties and laws there is no need to include them in the supervenience base. (shrink)

This paper discusses in broad terms the metaphysical projects of Sydney Shoemaker’s Physical Realization . Specifically, I examine the effectiveness of Shoemaker’s novel “subset” account of realization for defusing the problem of mental causation, and compare the “subset” account with the standard “second-order” account. Finally, I discuss the physicalist status of the metaphysical worldview presented in Shoemaker’s important new contribution to philosophy of mind and metaphysics.

This paper explores the fundamental ideas that have motivated the idea of emergence and the movement of emergentism. The concept of reduction, which lies at the heart of the emergence idea is explicated, and it is shown how the thesis that emergent properties are irreducible gives a unified account of emergence. The paper goes on to discuss two fundamental unresolved issues for emergentism. The first is that of giving a “positive” characterization of emergence; the second is to give a coherent (...) explanation of how “downward” causation, a central component of emergentism, is able to avoid the problem of overdetermination.

Jaegwon Kim’s causal exclusion argument says that if all physical effects have sufficient physical causes, and no physical effects are caused twice over by distinct physical and mental causes, there cannot be any irreducible mental causes. In addition, Kim has argued that the nonreductive physicalist must give up completeness, and embrace the possibility of downward causation. This paper argues first that this extra argument relies on a principle of property individuation, which the nonreductive physicalist need not accept, and second that (...) once we get clear on overdetermination, there is a way to reject the exclusion principle upon which the causal exclusion argument depends, but third that this should not lead to the belief that mental causation is easily accounted for in terms of counterfactual dependencies.

I survey recent work on mental causation. The discussion is conducted under the twin presumptions that mental states, including especially what subjects believe and desire, causally explain what subjects do, and that the physical sciences can in principle give a complete explanation for each and every bodily movement. I start with sceptical discussions of various views that hold that, in some strong sense, the causal explanations offered by psychology are autonomous with respect to those offered by the physical sciences. I (...) then proceed to views that see the problem of mental causation as that of identifying where in the physical story about us and our world lie the parts that in effect tell us abut mental causation - the kind of position that is pretty much standard in the cognitive science community - and consider issues raised by various forms of functionalism and externalism. The general thrust of my discussion is sympathetic to the story about mental causation suggested by those type-type versions of the mind-brain identity theory that allow for the possiblity of multiple realisability. I include a brief discussion of how a map-system account of belief, by contrast with a language of thought one, should understand explanations of behaviour in terms of what a subject believes.

Samuel Alexander was one of the foremost philosophical figures of his day and has been argued by John Passmore to be one of ‘fathers’ of Australian philosophy as well as a novel kind of physicalist. Yet Alexander is now relatively neglected, his role in the genesis of Australian philosophy if far from widely accepted and the standard interpretation takes him to be an anti-physicalist. In this paper, I carefully examine these issues and show that Alexander has been badly, although understandably, (...) misjudged by most of his contemporary critics and interpreters. Most importantly, I show that Alexander offers an ingenious, and highly original, version of physicalism at the heart of which is a strikingly different view of the nature of the microphysical properties and associated view of emergent properties. My final conclusion will be that Passmore is correct in his claims both that Alexander is significant as one of the grandfather’s of Australian philosophy and that he provides a novel physicalist position. I will also suggest that Alexander’s emergentism is important for addressing the so-called ‘problem of mental causation’ presently dogging contemporary non-reductive physicalists. (shrink)

The problem of downward causation is that an intuitive response to an intuitive picture leads to counterintuitive results. Suppose a mental event, m1, causes another mental event, m2. Unless the mental and the physical are completely independent, there will be a physical event in your brain or your body or the physical world as a whole that underlies this event. The mental event occurs at least partly in virtue of the physical event’s occurring. And the same goes for m2 [2] (...) and p2. Let’s not worry about what exactly “underlying” or “in virtue of” means here. Here’s the picture. m1 -----> m2 | | p1 -----> p2 The horizontal arrows represent causation, and the vertical lines represent underlying, whatever that may be. There’s some reason to think that the only way m1 can bring about m2 is by bringing about p2. You can’t convince someone of something through mental telepathy. You need to interact with the physical world, perhaps by saying something and so making some noise, or by pointing and getting them to turn their head and see. What goes for the case of two people goes for the case of one person as well. Superstition aside, there is no purely mental energy that floats free of the merely physical workings of the brain. If m1 brings about m2 by bringing about p2, then m1 brings about p2. This is downward causation. But wait. Doesn’t p1 bring about p2? Isn’t that what the bottom arrow represents? Maybe m1 and p1 work together to bring about p2. There are little holes in the physical causal structure that need to be filled by mental events. You don’t need a sweeping metaphysical thesis about the causal closure of the physical to find this implausible. Maybe p2 is overdetermined. (shrink)

Recent work by Jaegwon Kim and others suggest that functionalism leaves mental properties causally inefficacious in some sense. I examine three lines of argument for this conclusion. The first appeals to Occam's Razor; the second appeals to a ban on overdetermination; and the third charges that the kind of response I favor to these arguments forces me to give up "the homogeneity of mental and physical causation". I show how each argument fails. While I concede that a positive theory of (...) mental causation is desirable, there is no reason to think that functionalism renders such a theory unattainable. (shrink)

Here I offer a precise analysis of what it takes for a property to count as emergent. The features widely considered crucial to emergence include novelty, unpredictability, supervenience, relationality, and downward causal influence. By acknowledging each of these distinctive features, the definition provided below captures an important sense in which the whole can be more than the sum of its parts.

In some recent articles, Jaegwon Kim has argued that non-reductive physicalism is a myth: when it comes to the mind-body problem, the only serious options are reductionism, eliminativism, and dualism.[1] And when it comes to reductionism, Kim is inclined to regard a functionalist theory of the mind as the best available option—mostly because it offers the best explanation of mind-body supervenience. In this paper, I will discuss Kim’s views about functionalism. They may be contended on two general grounds. First, some (...) functionalists will object to being classified as reductionists. Second, Kim argues for a version (or a reading) of functionalism, conceptualized functionalism, that makes it rather similar to the “old” mind-body identity theory it was designed to replace. Moreover, Kim’s conceptualized functionalism turns out to be a somewhat surprising brand of reductionism—a reductionism with some eliminativist cut-outs and, possibly, some dualist leftovers. At the end of the paper I propose a construal of the more standard version of functionalism that obviates Kim’s argument for switching-over to his conceptualized version. (shrink)

This paper is about a puzzle which lies at the heart of contemporary physicalist theories of mind. On the one hand, the original motivation for physicalism was the need to explain the place of mental causation in the physical world. On the other hand, physicalists have recently come to see the explanation of mental causation as one of their major problems. But how can this be? How can it be that physicalist theories still have a problem explaining something which their (...) physicalism was intended to explain in the first place? If physicalism is meant to be an explanation of mental causation, then why should it still face the problem of mental causation? (shrink)

We argue that intelligible appeals to interlevel causes (top-down and bottom-up) can be understood, without remainder, as appeals to mechanistically mediated effects. Mechanistically mediated effects are hybrids of causal and constitutive relations, where the causal relations are exclusively intralevel. The idea of causation would have to stretch to the breaking point to accommodate interlevel causes. The notion of a mechanistically mediated effect is preferable because it can do all of the required work without appealing to mysterious interlevel causes. When interlevel (...) causes can be translated into mechanistically mediated effects, the posited relationship is intelligible and should raise no special philosophical objections. When they cannot, they are suspect. (shrink)

The standard paradigm for mental causation is a person’s acting for a reason. Something happens - she intentionally φ’s - the occurrence of which we explain by citing a relevant belief or desire. In the present context, I simply take for granted the following two conditions on the appropriateness of this explanation. First, the agent φ’s _because_ she believes/desires what we say she does, where this is expressive of a _causal_ dependence.1 Second, her believing/desiring this gives her a _reason_ for (...) φ-ing: recognizing that she has this belief/desire makes her φ-ing intelligible as rational in the light of her other attitudes and circumstances. A further condition must be met, though, if this is to be a genuine psychological explanation, a case of her acting _for_ the reason in question. Consider the following example of Davidson’s (1973, p. 79). An exhausted climber is desperate to rid herself of the weight and danger of holding her partner on a rope; and her sudden realization that simply letting go would achieve this so unnerves her that her grip loosens slightly and he falls. Her releasing him causally depends upon her having this belief and desire, which provide _a_ reason for doing what she does. But this is not _why_ she does it: it would be at best misleading to say that she dropped him, intentionally, because she was fed up with holding his weight, or because she thought that she might otherwise fall. Her letting go does not depend upon her having these reasons in the right way. The reason-giving relation is causally irrelevant. If we are to explain a person’s acting _for_ a reason, then her doing. (shrink)

Concerns about ‘mental causation’ are concerns about how it is possible for mental states to cause anything to happen. How does what we believe, want, see, feel, hope, or dread manage to cause us to act? Certain positions on the mind-body problem—including some forms of physicalism—make such causation look highly problematic. This entry sketches several of the main reasons to worry, and raises some questions for further investigation.

These (...) issues are brought to light and examined in some detail. (shrink)

Jaegwon Kim is one of the most preeminent and most influential contributors to the philosophy of mind and metaphysics. This collection of essays presents the core of his work on supervenience and mind with two sets of postscripts especially written for the book. The essays focus on such issues as the nature of causation and events, what dependency relations other than causal relations connect facts and events, the analysis of supervenience, and the mind-body problem. A central problem in the philosophy (...) of mind is the problem of explaining how the mind can causally influence bodily processes. Professor Kim explores this problem in detail, criticizes the nonreductionist solution of it, and offers a modified reductionist solution of his own. Both professional philosophers and their graduate students will find this an invaluable collection. (shrink)
