The basic form of the exclusion problem is by now very, very familiar. 2 Start with the claim that the physical realm is causally complete: every physical thing that happens has a sufficient physical cause. Add in the claim that the mental and the physical are distinct. Toss in some claims about overdetermination, give it a stir, and voilá—suddenly it looks as though the mental never causes anything, at least nothing physical. As it is often put, the physical does all (...) the work, and there is nothing left for the mental to do. (shrink)

This paper tries to remove some obstacles standing in the way of considering mental properties as both genuine natural kinds and causally efficacious rather than epiphenomena. As the case of temperature shows, it is not justified to conclude from a property being multiply realizable to it being irreducible. Yet Kim's argument to the effect that if a property is multiply realizable with a heterogeneous reduction base then it cannot be a natural kind and possesses only derivative “epiphenomenal” causal efficacy is (...) not conclusive either. The fact that temperature is, but jade is not, a natural kind cannot be established by comparing the heterogeneity of their respective reduction bases, but rather by the fact that the former is and the latter is not embedded in laws of nature.

For nearly thirty years, there has been a consensus (at least in English-speaking countries) that reductionism is a mistake and that there are autonomous special sciences. This consensus has been based on an argument from multiple realizability. But Jaegwon Kim has argued persuasively that the multiple realizability argument is flawed.1 I will sketch the recent history of the debate, arguing that much --but not all--of the anti-reductionist consensus survives Kim's critique. This paper was originally titled "Anti-Reductionism Strikes Back", but in (...) the course of writing the paper, I came to think that the concepts used in the debate would not serve either position very well.

In this paper, I explain and assess Karen Bennett’s solution to the exclusion problem. I begin by explaining and motivating Bennett’s formulation of the exclusion problem. Bennett’s formulation of the problem is unique in that it’s not a pointed argument against any one particular view; rather, her formulation sets up the problem as a set of inconsistent claims, at least one of which must be denied to remove the inconsistency. I then explain and motivate Bennett’s solution. Bennett creates a counterfactual (...) test for overdetermination, which is meant to show that the non-reductivist account of mental causation does not result in rampant overdetermination. Next, I explain and motivate a recent objection to Bennett’s solution by Chiwook Won. Won’s charge is that Bennett’s counterfactuals are not necessary for overdetermination. However, I will show that Won does not assess the counterfactuals in Bennett’s test correctly and, thus, Bennett’s solution remains viable. (shrink)

This paper criticizes the account of desire defended by Nomy Arpaly and Timothy Schroeder in their recent book, In Praise of Desire. It contrasts their account with one that I favor, a cluster analysis listing various criteria that are together sufficient for having paradigm desires, but none of which is necessary or sufficient for desiring. I argue that their account fails to state necessary or sufficient conditions, that it is explanatorily weaker than the cluster account, that it fails to provide (...) a neat reduction of desires to neurophysical terms, and that in any case such a reduction is not required for the preservation of the concept of desire in mature psychology. Implications are drawn for the broader debate between reductionists, eliminativists, and defenders of folk psychological concepts. (shrink)

The article is a critical notice of Daniel Garber, Leibniz: Body, Substance, Monad. Garber presents a developmental reading of Leibniz's metaphysics that focuses on Leibniz's evolving analysis of body and force as the key to his account of substance. Garber claims that Leibniz shifts from an early theory of body to a theory of corporeal substance in his middle years, and only develops a theory of monads in his later writings—and that even then Leibniz looks not to abandon the scheme (...) of corporeal substances but to reconcile it with that of monads. The present article considers several challenges to Garber's interpretation, questioning, among other things, Garber's claims about development and Garber's account of Leibniz's primary arguments for the theory of monads. The article concludes that while crucial elements of the standard interpretation of Leibniz as an idealist can be defended against Garber's critique, the original traditional view that takes the theory of monads as the first and most fundamental principle of Leibniz's metaphysics is no longer sustainable.

Recent work in the methodology of connectionist explanation has I'ocrrsccl on the notion of levels of explanation. Specific issucs in conncctionisrn hcrc intersect with rvider areas of debate in the philosophy of psychology and thc philosophy of science generally. The issues I raise in this chapter, then, are not unique to cognitive science; but they arise in new and important contexts when connectionism is taken seriously as a model of cognition. The general questions are the relation between levels and the (...) status of levels which have no obvious relation to others. In speaking of levels, what is the connection, if there is one, between explanation and ontology? Which, if any, conccpt of reduction is applicable to connectionist systems? What kind of legitinrtcy can the constructs of common sense psychology, or of that vclsion ol intentional realism represented by classical symbol-systems n I, hirvc irr ir full-scale connectionist theory of mind?

In philosophy, the last thirty years or so has seen a split between 'simulation theorists' and 'theory-theorists', with a number of variations on each side. In general, simulation theorists favour the idea that our knowledge of others is based on using ourselves as a working model of what complex psychological creatures are like. Theory-theorists claim that our knowledge of complex psychological creatures, including ourselves, is theoretical in character and so more like our knowledge of the world in general. The body (...) of this paper is divided into three parts. In Part I, I introduce the 'contrastive case' of autism. Autism is a developmental disorder that has recently become the focus of sustained philosophical and psychological attention because of the selective way in which it affects individuals' social capacities. Theory-theorists argue that autistic children's unique profile of assets and deficits is most fruitfully explained by their inability to develop and deploy a theory of mind. After considering the strengths of this hypothesis, I claim theory-theorists face two unresolved difficulties: explaining why high-functioning autistics who develop some theory of mind capacities still fail to engage in normal psychological knowing; and explaining why autistics are generally as unknowable to us in the privileged sense of normal psychological knowing as we are to them. In Part II, I provide the theoretical framework for addressing these challenges by developing an account of normal psychological knowing as psycho-practical expertise. In Part III, I return to the problem of autism, showing how this psycho-practical approach to normal psychological knowing may further suggest how to encompass various aspects of the disorder that tend to be ignored under the prevailing theory-theory approach.

In this paper it is argued that we would not be logically obliged or rationally inclined to reject the ontology of contentful psychological states postulated by folk psychology even if the explanations advanced by folk psychology turned out to be generally inaccurate or inadequate. Moreover, it is argued that eliminativists such as Paul Churchland do not establish that folk psychological explanations are, or are likely to prove, generally inaccurate or inadequate. Most of Churchland's arguments—based upon developments within connectionist neuroscience—only cast (...) doubt upon the adequacy of 'sentential' theories of cognitive processing, not upon scientifically developed forms of folk psychological explanation of behavior, such as those offered by contemporary social psychology. Finally, it is noted that Churchland's brand of eliminativism rests upon a crude reductive criterion of theoretical adequacy that has little to recommend it, and suggested that the recognized theoretical limitations of contemporary social psychology may be precisely due to its historical commitment to this reductive criterion.

Many philosophers accept some version of a principle that says for all x, if x exists, then x plays a unique causal role. After briefly clarifying one version of the principle in Section 1, Section 2 gives reasons to doubt it by showing that there are non-identical “causal indiscernibles”—I call them “married causes.” Section 3 then sketches a few philosophical puzzles for which married causes may be helpful.

A popular claim in recent philosophy of mind and action is that events only exist once they are over. This has been taken to have the consequence that many temporal phenomena cannot be understood ‘from the inside’, as they are unfolding, purely in terms of events. However, as I argue here, the claim that events exist only when over is incoherent. I consider two ways of understanding the claim and the notion of existence it involves: one that ties existence to (...) the logic of quantification, and another that assimilates the existence of an event to that of a continuant. The first of these, I argue, cannot be the right way to understand the target claim, as there are serious logical obstacles to regarding this notion of existence as temporally variable. The second, on the other hand, leaves it ultimately mysterious what the existence of an event could amount to. I close with the suggestion that the undeniable temporal asymmetries which parties to the debate are interested in are properly understood in perspectival, not ontological, terms. (shrink)
