This entry concerns dualism in the philosophy of mind. The term ‘dualism’ has a variety of uses in the history of thought. In general, the idea is that, for some particular domain, there are two fundamental kinds or categories of things or principles. In theology, for example a ‘dualist’ is someone who believes that Good and Evil — or God and the Devil — are independent and more or less equal forces in the world. Dualism contrasts with monism, which is the theory that there is only one fundamental kind, category of thing or principle; and, rather less commonly, with pluralism, which is the view that there are many kinds or categories. In the philosophy of mind, dualism is the theory that the mental and the physical — or mind and body or mind and brain — are, in some sense, radically different kinds of thing. Because common sense tells us that there are physical bodies, and because there is intellectual pressure towards producing a unified view of the world, one could say that materialist monism is the ‘default option’. Discussion about dualism, therefore, tends to start from the assumption of the reality of the physical world, and then to consider arguments for why the mind cannot be treated as simply part of that world.

In Consciousness Explained, Dennett elaborates and defends a materialist?functionalist account of the human mind, and of consciousness in particular. This defence depends crucially on his prior rejection of dualism. Dennett rejects this dualist alternative on three grounds: first, that its version of mind?to?body causation is in conflict with what we know, or have good reason to believe, from the findings of physical science; second, that the very notion of dualistic psychophysical causation is incoherent; and third, that dualism puts the mind beyond the reach of scientific investigation. In each case, his reasoning is unconvincing, and indeed leaves the dualist entirely unscathed. In contrast, without an adequate basis for his rejection of dualism, Dennett himself is left with a theory which is vulnerable to a number of familiar objections.

The problem of consciousness seems to arise from experience itself. As we shall consider in more detail below, we are strongly disposed to contrast conscious experience with the physical states or events by which we take it to be realized. This contrast gives rise to dualism and other problems of mind and body. In this chapter I argue that these problems can usefully be considered in the perspective of evolution.

The mind-body problem concerns the relationship between mind and body, or nowadays - between mind or consciousness and the brain. As a relationship, this can be viewed from two perspectives: from body to mind and from mind to body. In this note I point out that the two readings of the problem are not symmetrical and that there are categorical differences between them. In particular, whereas the body to mind problem constitutes a mystery (cf. the contemporary hard problem), the mind to body problem may be approached from a psychological (as contrasted with philosophical) orientation that allows for concrete phenomenological investigation.

Introduction -- Consciousness : what is the problem? -- Consciousness : how should it be studied? -- Is the mind physical? -- How is your mind related to your body? : how is it related to the world? -- What is the self? -- What can pathological cases teach us about the mind? -- How can we know whether-and what-non-human animals think? -- Can machines think? -- Is there intelligent life on other planets?

Is consciousness all in the head, or might the minimal physical substrate for some forms of conscious experience include the goings on in the (rest of the) body and the world? Such a view might be dubbed (by analogy with Clark and Chalmers’s ( 1998 ) claims concerning ‘the extended mind’) ‘the extended conscious mind’. In this article, I review a variety of arguments for the extended conscious mind, and find them flawed. Arguments for extended cognition, I conclude, do not generalize to arguments for an extended conscious mind.

Associated with the successful development of computer technology has been an increasing acceptance of computational theories of the mind. But such theories also seem to close the gap between ourselves and machines, threatening traditional notions of our special value as non-physical conscious minds. Prima facie, Sāmkhya-Yoga - the oldest school of classical Indian philosophy, with its dualism between purusa ('self', 'consciousness') and prakrti ('nature', 'matter') - seems a case in point. However, Sāmkhya-Yoga dualism is not straightforwardly a mind-body dualism and in order to understand exactly where it stands on the mind-body problem we need a more nuanced characterisation of that problem than is usual. Once this is done, it seems that Sāmkhya-Yoga may well be able to accommodate the most plausible parts of the computational theory of mind.

Colin McGinn presents his latest work on consciousness in ten interlinked papers, four of them previously unpublished. He extends and deepens his controversial solution to the mind-body problem, defending the view that consciousness is both ontologically unproblematic and epistemologically impenetrable. He also investigates the basis of our knowledge that there is a mind-body problem, and the bearing of this on attempted solutions. McGinn goes on to discuss the status of first-person authority, the possibility of atomism with respect to consciousness, extreme dualism, and the role of non-existent objects in constituting intentionality. He argues that traditional claims about our knowledge of our own mind and of the external world can be inverted; that atomism about the conscious mind might turn out to be true; that dualism is more credible the more extreme it is; and that all intentionality involves non-existent objects. These are all surprising positions, but he contends that what the philosophy of mind needs now is 'methodological radicalism' - a willingness to consider new and seemingly extravagant ideas.
