The famous ethological maxim known as “Morgan’s Canon” continues to be the subject of interpretive controversy. I reconsider Morgan’s canon in light of two questions: First, what did Morgan intend? Second, is this, or perhaps some re-interpretation of the canon, useful within cognitive ethology? As for the first issue, Morgan’s distinction between higher and lower faculties is suggestive of an early supervenience concept. As for the second, both the canon in its original form, and various recent re-readings, offer nothing useful (...) to cognitive ethology. (shrink)

This is an essay on McDowell’s naturalism. It is, pace some commentators, argued that McDowell’s naturalism does not end up in any strange metaphysical positions in the philosophy of mind, because second nature non-reductively supervenes on first nature and have causal powers. Pace certain other commentators, it is also argued that McDowell can be read as drawing a clear line between ethical platonism, and his own naturalized platonism, but only at the cost of landing in standard naturalism.

We evaluate the scope of Jaegwon Kim's “supervenience argument” for reduction. Does its conclusion apply only to psychology, or does it generalize to all the special sciences? The claim that the supervenience argument generalizes to all the special sciences if it goes through for psychology is often raised as an objection to the supervenience argument. We argue that this objection is ambiguous. We distinguish three readings of it and suggest that some of them make it a plausible claim, whereas other (...) readings make it implausible. We suggest that this ambiguity is the result of picturing the world as being hierarchically organized in levels, with the domain of physics at the bottom and the domains of the social sciences at the top. The plausibility of the objection depends on how we think of this picture. This popular picture, we suggest, involves three different dimensions along which reduction may occur. (shrink)

This is a handout developing one argument for the view that relations like assertion are borne simultaneously to vast numbers of very similar propositions, rather than to a single proposition.

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.

Turing's celebrated 1950 paper proposes a very general methodological criterion for modelling mental function: total functional equivalence and indistinguishability. His criterion gives rise to a hierarchy of Turing Tests, from subtotal ("toy") fragments of our functions (t1), to total symbolic (pen-pal) function (T2 -- the standard Turing Test), to total external sensorimotor (robotic) function (T3), to total internal microfunction (T4), to total indistinguishability in every empirically discernible respect (T5). This is a "reverse-engineering" hierarchy of (decreasing) empirical underdetermination of the theory (...) by the data. Level t1 is clearly too underdetermined, T2 is vulnerable to a counterexample (Searle's Chinese Room Argument), and T4 and T5 are arbitrarily overdetermined. Hence T3 is the appropriate target level for cognitive science. When it is reached, however, there will still remain more unanswerable questions than when Physics reaches its Grand Unified Theory of Everything (GUTE), because of the mind/body problem and the other-minds problem, both of which are inherent in this empirical domain, even though Turing hardly mentions them.

Trenton Merricks argues against the following doctrine: Microphysical Supervenience (MS) Necessarily, if atoms A1 through An compose an object that exemplifies intrinsic qualitative properties Q1 through Qn, then atoms like A1 through An (in all their respective intrinsic qualitative properties), related to one another by all the same restricted atom-to-atom relations as A1 through An, compose an object that exemplifies Q1 through Qn. (Merricks 1998, p. 59) Imagine a person, _P_. Microphysical Supervenience entails that there is an object, the finger-complement, (...) wholly composed of all of _P_'s atoms except those in _P_'s left index-finger. After all, when we slice off _P_'s finger, we leave atoms micro- indiscernible from those in the finger-complement, and _those_ atoms compose an object, maimed _P_. Moreover, if _being conscious_ is an intrinsic property, then Microphysical Supervenience entails that the finger-complement is conscious, for maimed _P_ is conscious. But this, argues Merricks, is "simply incredible". It cannot be the case that every large collection of _P_'s atoms forms a conscious object, for then there would be "a mighty host" of conscious objects sitting in _P_'s chair (Merricks 1998, p.63). Even if there is a finger-complement, it is not conscious. So _being_ _conscious_ does not supervene upon microphysical arrangements: if _being conscious_ is an intrinsic qualitative property then Microphysical Supervenience is false. Merricks argues that _being conscious_ is indeed intrinsic, and thus that Microphysical Supervenience _is_ false. He has two reasons for supposing _being conscious_ to be intrinsic, and I object to both of these. (shrink)

I put forward and defend the thesis (Th) that psychophysical supervenience (PS) in its full generality can be satisfactorily supported if and only if one is willing to make one or another of some substantial assumptions (the Assumptions) about the nature of mental and physical properties. I first deal with the “if” part of the claim by presenting and considering the Assumptions. I then argue for the inadequacy of suggestions of support for PS that do not require any of the (...) Assumptions. Finally, I show that as a result of (Th) a PS claim is made potentially stronger than what it would be if (Th) were false. (shrink)

Functional reductionism concerning mental properties has recently been advocated by Jaegwon Kim in order to solve the problem of the 'causal exclusion' of the mental. Adopting a reductionist strategy first proposed by David Lewis, he regards psychological properties as being 'higher-order' properties functionally defined over 'lower-order' properties, which are causally efficacious. Though functional reductionism is compatible with the multiple realizability of psychological properties, it is blocked if psychological properties are subdivided or crosscut by neurophysiological properties. I argue that there is (...) recent evidence from cognitive neuroscience that shows that this is the case for the psychological property of fear. Though this may suggest that some psychological properties should be revised in order to conform to those of neurophysiology, the history of science demonstrates that this is not always the outcome, particularly with properties that play an important role in our folk theories and are central to human concerns.

On a widely shared assumption, our mental states supervene on our microphysical properties – that is, microphysical supervenience is true. When this thesis is combined with the apparent truism that human persons have proper parts, a grave difficulty arises: what prevents some of these proper parts from being themselves thinkers as well? How can I know that I am a human person and not a smaller thinker enclosed in a human person? Most solutions to this puzzle make radical, if not (...) absurd, claims. Recently, however, Michael Burke and Howard Robinson proposed conservative solutions that, according to them, do not have such undesired consequences. This paper argues that the conservative solutions tacitly assume at least one of the radical ones, and therefore they provide no alternative to the extreme solutions. (shrink)

An important part of the mind-brain problem arises because sentience and consciousness seem inherently resistant to scientific explanation and understanding. The solution to this dilemma is to recognize, first, that scientific explanation can only render comprehensible a selected aspect of what there is, and second, that there is a mode of explanation and understanding, the personalistic, quite different from, but just as viable as, scientific explanation. In order to understand the mental aspect of brain processes - that aspect we know (...) about as a result of having relevant neurological processes occur in our own brain - we need to avail ourselves of personalistic explanation, irreducible to scientific explanation. The problem of explaining and understanding why experiential or mental aspects of brain processes or things should be correlated with certain physical processes, things or states of affairs is a non-problem because there is no kind of explanation possible in terms of which an explanation could be couched. A physical theory, amplified to include the experiential, might be predictive but would, necessarily, cease to be explanatory; and an amplified personalistic explanation could not succeed either. There is, in short, an explanation as to why there cannot be an explanation of correlations between physical and mental aspects of processes going on inside our heads. (shrink)

In this paper, I examine, from a metaphysical point of view, a recent notable attempt by Jaegwon Kim to explain how macro-events are dependent on micro-events and how causal transactions between macro-events are dependent on causal transactions between micro-events.

The doctrine of Microphysical Supervenience (MS) states that: Necessarily, if atoms A1 through An compose an object that exemplified intrinsic qualitative properties Q1 through Qn, then atoms like A1 through An (in all their respective intrinsic qualitative properties), related to one another by all the same restricted atom-to-atom relations as A1 through An, compose an object that exemplifies Q1 through Qn. I show that MS entails a contradiction and so must be rejected. And my argument against MS provides the resources (...) to show that Global Microphysical Supervenience (GMS) is false. GMS states that possible worlds qualitatively exactly alike at the microphysical level are qualitatively exactly alike at the macrophysical level. (shrink)

The aim of the paper is to discuss some recent variants of familiar puzzles concerning the relations of parts to wholes put forward by Trenton Merricks and Eric Olson. The argument is put forward that so long as the familiar distinction between 'loose and popular' and 'strict and philosophical' senses of identity claims is accepted the paradoxical conclusions at which Merricks and Olson arrive can be resisted. It is not denied that accepting the distinction between 'loose and popular' and 'strict (...) and philosophical' senses of identity claims is itself a departure from common-sense, but it is argued that it is the smallest such departure available to us.

Supervenience is one of the 'hot discoveries' of recent analytic philosophy, and this collection of new essays on the topic represents a 'state of the art' examination of it and its application to major areas of philosophy. The interest in supervenience has much to do with the flexibility of the concept. To say that x supervenes on y indicates a degree of dependence without committing one to the view that x can be reduced to y. Thus supervenience is a relationship (...) that has the potential of replacing the traditional notion of dependence, while performing at least part of the function reductive relationships were supposed to fulfil. Moreover, since it is a topic-neutral concept, supervenience has a wide range of applicability. (shrink)

A property, F, is maximal i?, roughly, large parts of an F are not themselves Fs. Maximal properties are typically extrinsic, for their instantiation by x depends on what larger things x is part of. This makes trouble for a recent argument against microphysical superve- nience by Trenton Merricks. The argument assumes that conscious- ness is an intrinsic property, whereas consciousness is in fact maximal and extrinsic.

This collection brings together previously unpublished works by well-known philosophers on the philosophy of action, the metaphysics of causality, and the philosophy of psychology. Nine of the essays directly discuss Donald Davidson's work on these topics, while three others challenge a Davidsonian approach through discussion of independent but related issues. These essays are followed by replies from Davidson, including a previously unpublished essay, "Adverbs of Action.".

This paper examines the widespread intuition that the dynamical approach to cognitive science is importantly related to emergentism about the mind. The explanatory practices adopted by dynamical cognitive science rule out some conceptions of emergence; covering law explanations require a deducibility relationship between explanans and explanandum, whereas canonical theories of emergence require the absence of such deducibility. A response to this problem – one which would save the intuition that dynamics and emergence are related – is to reconstrue the concept (...) of emergence as a relationship between laws. I call this “nomological emergence” and comment on the extent to which dynamicists would find it acceptable. Alternatively, dynamical cognitive science might be viewed as fitting better with the kind of “functional reductionism” which has recently been developed by authors such as Jaegwon Kim. Which of these two alternatives is preferable remains an open question pending the further development of dynamical cognitive science, particularly in its “non-classical” forms. (shrink)

This paper is an attempt to understand the content of, and motivation for, a popular form of physicalism, which I call ‘non-reductive physicalism’. Non-reductive physicalism claims although the mind is physical (in some sense), mental properties are nonetheless not identical to (or reducible to) physical properties. This suggests that mental properties are, in earlier terminology, ‘emergent properties’ of physical entities. Yet many non-reductive physicalists have denied this. In what follows, I examine their denial, and I argue that on a plausible (...) understanding of what ‘emergent’ means, the denial is indefensible: non-reductive physicalism is committed to mental properties being emergent properties. It follows that the problems for emergentism—especially the problems of mental causation—are also problems for non-reductive physicalism, and they are problems for the same reason. (shrink)

With ontology motivated largely by causal considerations, this lucid and provocative work focuses on the idea that physical objects are causally non-redundant. Merricks "eliminates" inanimate composite macrophysical objects on the grounds that they would--if they existed--be at best completely causally redundant. He defends human existence by arguing, from certain facts about mental causation, that we cause things that are not determined by our proper parts. He also provides insight into a variety of philosophical puzzles, while addressing many significant issues like (...) free will, the "reduction" of a composite object to its parts, and the ways in which identity over time can "for practical purposes" be a matter of convention. Anyone working in metaphysics will enjoy this book immensely. (shrink)

Recent work in the Philosophy of Mind has suggested that alternatives to reduction are required in order to explain the relationship between psychology and biology or physics. Emergence has been proposed as one such alternative. In this paper, I propose a precise definition of emergence, and I argue that chaotic systems provide concrete examples of properties that meet this definition. In particular, I suggest that being in the basin of attraction of a strange attractor is an emergent property of any (...) chaotic nonlinear dynamical system. This shows that non-reductive accounts of inter-theoretic relations are necessary, and that non-reductive accounts of the mental are possible. Moreover, this work provides a foundation for future work investigating the nature of explanation, prediction, and scientific understanding of non-reductive phenomena. (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)

Commonsense psychological explanations are an integral part of a comprehensive commonsense background that includes almost everything that we deal with everyday— from traffic jams to paychecks to cozy dinners for two. It is the comprehensive commonsense background that I think is not wholesale refutable by science. A good deal of the comprehensive commonsense background itself depends on there being beliefs, desires, intentions and other propositional attitudes. If there never have been propositional attitudes, then there never have been statues or schools (...) or terrorists or Nobel prizes. Since I think it unreasonable to suppose that science will reveal that there never has been a statue, or a school or a terrorist or a Nobel prize, I also think it unreasonable to suppose that science will reveal that nobody has ever had a belief, desire, intention or other propositional attitude.1.

Terry Horgan has made impressive and highly important contributions to numerous fields of philosophy ? metaphysics, philosophy of mind and psychology, philosophy of language, philosophy of science, and value theory, to mention the most prominent ones. What gives Horgan's work a powerful and clarifying unity is his deep and unflagging commitment to philosophical naturalism. In fact, Horgan himself has often invoked naturalism to motivate his positions and arguments on a number of philosophical issues. In this talk, I will discuss some (...) questions concerning Horgan's naturalism and his philosophy of mind.Among them are such questions as these: What exactly is the naturalism that drives Horgan's philosophical thinking? Is it a reasonable and plausible form of naturalism? Exactly how does his naturalism lead to the conclusions and arguments he defends? Should "proper" naturalists follow Horgan's lead? I will discuss these questions in relation to Horgan's work on mind-body supervenience, the autonomy of psychological explanation, reductionism, mental causation, and related issues. (shrink)

In recent decades, a view of identity I call Sortalism has gained popularity. According to this view, if a is identical to b, then there is some sortal S such that a is the same S as b. Sortalism has typically been discussed with respect to the identity of objects. I argue that the motivations for Sortalism about object-identity apply equally well to event-identity. But Sortalism about event-identity poses a serious threat to the view that mental events are token identical (...) to physical events: A particular mental event m is identical with a particular physical event p only if there is a sortal S such that m and p are both Ss. If there is no such sortal, the doctrine of token-identity is not true. I argue here that we have no good reason for thinking that there is any such sortal. (shrink)

As part of his ongoing critique of metaphysical realism, Hilary Putnam has recently argued that current materialist theories of mind that locate mental phenomena in the brain can make no sense of the proposed identifications of mental states with physical (or physical cum computational) states, or of the supervenience of mental properties with physical properties. The aim of this paper is to undermine Putnam's objections and reassert the intelligibility – and perhaps the plausibility – of some form of mind-body identity (...) and supervenience. (shrink)

Naturalism about the mind is often taken to be equivalent to some form of physicalism: the existence of mental properties must be shown not to compromise the autonomy of the physical realm. It is argued that this leads to a choice between reductionism, eliminativism, epiphenomenalism or interactionism. The central aim of the paper is to outline an Aristotelian alternative to the physicalist conception of natural bodies. It is argued that the distinction between form and matter, and an ontology which treats (...) individual natural bodies as real, unified things, rather than as complexes, enables us to achieve the non-reductionist, non-epiphenomenalist and non-interactionist position which eludes the post-Cartesian. (shrink)

I argue that there are good reasons to deny both type-type and token-token mind-brain identity theories. Yet on the other hand there are compelling reasons for thinking that there is a causal basis for the mind. I argue that a path out of this impasse involves not only showing that criteria of individuation do not determine identity, but also that there are sound methodological reasons for thinking that the cause of intelligent behavior is a real natural kind. Finally, a commitment (...) to this methodology suggests both that these familiar anti-reductionist arguments fail to establish that identity is impossible and at the same time suggest that the preferred alternative will be some version of neutral monism.

The analysis of mental concepts suggests that the distinctionbetween the mental and the nonmental is not ontologically fundamental,and that, whereas mental processes are one and the same things as thebrain processes with which they are correlated, dispositional mentalstates depend causally on and are, thus, ''''distinct existences'''' fromthe states of the brain microstructure with which ''they'' are correlated.It is argued that this difference in the relation between an entity andits composition/underlying structure applies across the board. allstuffs and processes are the same (...) thing as is described by a descriptionof their microstructure. In all cases where the manifestation of adisposition extends beyond the ''''skin'''' of the dispositional propertybearer, dispositions invariably depend causally on the structure,usually the microstructure, of the bearer.

"Of Minds and Molecules" attempts to show the difficulties in mental-state brain-state monism. By exploring the differences in meaning between mental-state sentences and brain-state sentences, and by analysing the implications of the theory of the molecular composition of matter, a kind of dualism is arrived at that no scientist should feel uncomfortable with. It is a dualism without mental substance but it does not deprive mental states of their uniqueness. Arguments are given for the propriety of asserting causal connections and (...) dependency relations between mental states and molecular states of the brain. (shrink)

“Biological Naturalism” is a name I have given to an approach to what is traditionally called the mind-body problem. The way I arrived at it is typical of the way I work: try to forget about the philosophical history of a problem and remind yourself of what you know for a fact. Any philosophical theory has to be consistent with the facts. Of course, something we think is a fact may turn out not to be, but we have to start (...) with our best information. Biological Naturalism is a theory of mental states in general but as this book is about consciousness I will present it here as a theory of consciousness. (shrink)

Most scholars who presently deal with the Mind-Body problem consider themselves monist materialists. Nevertheless, many of them also assume that there exist (in some sense of existence) mental entities. But since these two positions do not harmonize quite well, the literature is full of discussions about how to reconcile the positions. In this paper, I will defend a materialist theory that avoids all these problems by completely rejecting the existence of mental entities. This is Quine's repudiation theory. According to the (...) theory, there are no mental entities, and the behavioral or physiological phenomena that have been attributed to mental entities, or that point to the existence of these entities, are exclusively caused by physiological factors. To be sure, several objections have been raised to materialist theories that do not assign some role to mental entities. But we will see that Quine is able to give convincing replies to these objections. (shrink)
