This book, based on Jaegwon Kim's 1996 Townsend Lectures, presents the philosopher's current views on a variety of issues in the metaphysics of the mind...

"This is a fine volume that clarifies, defends, and moves beyond the views that Kim presented in Mind in a Physical World.

EMERGENT EVOLUTION- THE GIFFORD LECTURES DELIVERED IN THE UNIVERSITY OF ST.

A framework for representing a specific kind of emergent property instance is given. A solution to a generalized version of the exclusion argument is then provided and it is shown that upwards and downwards causation is unproblematical for that kind of emergence. One real example of this kind of emergence is briefly described and the suggestion made that emergence may be more common than current opinions allow.

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.

The following framework of theses, roughly hewn, shapes contemporary discussion of the problem of mental causation: (1) Non-Identity of the Mental and the Physical Mental properties and states cannot be identified with specific physical properties and states. (2) Causal Closure (Completeness) of the Physical The objective probability of every physical event is fixed by prior physical events and laws alone. (This thesis is sometimes expressed in terms of explanation: In tracing the causal history of any physical event, one need not (...) advert to any non-physical events or laws. To the extent that there is any explanation available for a physical event, there is a complete explanation available couched entirely in physical vocabulary. We prefer the probability formulation, as it should be acceptable to any physicalist, though some reject the explanation formulation.) (3) Causal Exclusion There is at most one complete and wholly independent explanation for any given event or sequence of events. (shrink)

In this paper I will revisit an argument that I have called “the supervenience argument”; it is sometimes called “the exclusion argument” in the literature. I want to reconsider several aspects of this argument in light of some of the criticisms and comments it has elicited, clarifying some points and offering a slightly reformulated—and improved—version of the argument. My primary aim, however, is to discuss and respond to Ned Block’s edifying and challenging critique of the argument in his “Do Causal (...) Powers Drain Away?”—in particular, his claim that the argument has the consequence that if there is no bottom microphysical level, causal powers will “drain away”, leaving us with no causation anywhere. The supervenience argument was designed to show that on a certain popular and influential view of mentality and its relationship to the physical, mental properties turn out to be epiphenomenal, that is, without causal powers of their own.

Though most contemporary philosophers and scientists accept a physicalist view of mind, the recent surge of interest in the problem of consciousness has put the mind /body problem back into play. The physicalists' lack of success in dispelling the air of residual mystery that surrounds the question of how consciousness might be physically explained has led to a proliferation of options. Some offer alternative formulations of physicalism, but others forgo physicalism in favour of views that are more dualistic or that (...) bring in mentalistic features at the ground- floor level of reality as in pan-proto-psychism. My aim here is to give an overview of the recent philosophic discussion to serve as a map in locating issues and options. I will not offer a comprehensive survey of the debate or mark every important variant to be found in the recent literature. I will mark the principal features of the philosophic landscape that one might use as general orientation points in navigating the terrain. I will focus in particular on three central and interrelated ideas: those of emergence, reduction, and nonreductive physicalism. The third of these, which has emerged as more or less the majority view among current philosophers of mind, combines a pluralist view about the diversity of what needs to be explained by science with an underlying metaphysical commitment to the physical as the ultimate basis of all that is real. The view has been challenged from both left and right, on one side from dualists and on the other from hard core reductive materialists. Despite their differences, those critics agree in finding nonreductive physicalism an unacceptable and perhaps even incoherent position. They agree as well in treating reducibility as the essential criterion for physicality; they differ only about whether the criterion can be met. Reductive physicalists argue that it can, and dualists deny it. (shrink)

This paper explicates two notions of emergencewhich are based on two ways of distinguishinglevels of properties for dynamical systems.Once the levels are defined, the strategies ofcharacterizing the relation of higher level to lower levelproperties as diachronic and synchronic emergenceare the same. In each case, the higher level properties aresaid to be emergent if they are novel or irreducible with respect to the lower level properties. Novelty andirreducibility are given precise meanings in terms of the effectsthat the change of a bifurcation (...) or perturbation parameterin the system has. (The same strategy can be applied to otherways of separating levels of properties, like themicro/macro distinction.)The notions of emergence developed here are notions of emergencein a weak sense: the higher level emergent properties wecapture are always structural properties (or are realized insuch properties), that is, they are defined in terms of the lowerlevel properties and their relations. Diachronic and synchronicemergent properties are distinctions within thecategory of structural properties. (shrink)

In Mind in a Physical World (1998), Jaegwon Kim has recently extended his ongoing critique of `non-reductive materialist' positions in philosophy of mind by arguing that Nagel's model of reduction is the wrong paradigm in terms of which to contest the issue of psychophysical reduction, and that an altogether different model of scientific reduction – a functional model of reduction – is needed. In this paper I argue, first, that Kim's conception of the Nagelian model is substantially impoverished and potentially (...) misleading; second, that his own functional model is problematic in several respects; and, third, that the basic idea underlying his functional model can well be accommodated within a properly reinterpreted Nagelian model. I conclude with some reflections on the issue of psychophysical reduction. (shrink)

I will argue that emergence is an empirically plausible and unique philosophical/ scientific framework for bridging the ontological gap and the explanatory gap with respect to phenomenal consciousness. On my view the ontological gap is the gap between fundamental ingredients/parts of reality that are not conscious and beings/wholes that are conscious. The explanatory gap is the current lack of a philosophical/scientific theory that explains how non-conscious parts can become conscious wholes. Both gaps are of course conceptual as well as empirical (...) in nature. Section I will be devoted to these issues as well as providing other general criteria for an account of consciousness. In section II, different types of emergence will be defined in the context of a more general taxonomy of reduction and emergence. Emergentism about consciousness becomes much more plausible when we see that the ancient ‘atomism’ that drives physicalism on one end, and fundamental property dualism on the other, is probably false. Backing up this claim will be the primary burden of section III. In section IV I will conjecture that phenomenal consciousness is mereologically and perhaps nomologically emergent from neurochemical/ quantum processes, just as many other properties are so emergent. In section V I defend my view of emergence against the objections that: it cannot bridge the explanatory/ontological gap between matter and consciousness and it cannot account for the causal efficacy of consciousness in itself. Finally, in section VI, there is speculation about where all of this might take us in the future. (shrink)
