Certainly not for a graduate philosophy of mind class, May 27, 2000
It is quite ridiculous that someone should use Paul Churchland's Matter and Consciousness for a graduate class in philosophy of mind. Paul Churchland, for one, never intended it to be so, and certainly was not writing for such an audience. Having said that, Matter and Consciousness qualifies as one of the best brief introductions to pertinent issues in philosophy of mind. Do note, however, that Paul Churchland's focus is philosophical rather than psychological or cognitive. The book begins with a discussion of the mind-body problem and various standard proposed solutions, i.e. various forms of dualism, mind-brain identity theory, functionalism and the like. Each school of thought is presented in an orderly fashion, beginning with a brief outline of the general solution with a couple of examples, then proceeding to sections on the advantages and disadvantages of the school of thought in question. Now, as with all truly introductory surveys of academic disciplines, the discussions in Matter and Consciousness are superficial from the perspective of more mature students. However, its brevity and clarity make it probably the best introductory text to philosophy of mind around. I read Matter and Consciousness in a single sitting over a cup of tea, and vouch for its accessibility. Matter and Consciousness also has sections on the psychological, computational and neuroscientific side of things, and although much of the scientific material is dated, these sections still give the uninformed reader a general flavor of ongoing work in those areas, and much to contemplate. If Matter and Consciousness is being used for an introductory course on philosophy of mind, I would suggest augmenting the material in Matter and Consciousness by selecting appropriate readings from Lycan's Mind and Cognition: An Anthology. Matter and Consciousness was written quite awhile ago, when work in parallel distributed processing in AI was just being resurrected, and way before the embodied cognition revolution. Therefore, it would be an excellent idea to look at section 4 (Mind as a Computer: Machine Functionalism) of Kim's Philosophy of Mind for a fairly theoretical introduction to the ideas behind artificial intelligence, brief selections from Russell and Norvig's introductory AI text or Winston's AI text for an understanding of standard techniques (i.e. search, neural networks, production systems and the like) in AI, and Andy Clark's introduction to the foundations of AI, "Philosophical Foundations", in Artificial Intelligence (Handbook of Perception and Cognition) edited by Margaret Boden.

Pretty good introduction to a vexing problem, November 2, 2002
The mind-body problem, as it is called in Western philosophy, still has the attention of philosophers, despite centuries of debate. It will no doubt occupy more of philosophers time in the upcoming decades due to the resurging interest (and advances) in artificial intelligence. But the goal of most research in A.I. is now geared towards computational algorithms that are able to learn and can discover new knowledge or data patterns. The "hard A.I." problem, that of creating conscious machines, is not top priority it seems. But philosophers will continue with the analysis of the nature of conscious intelligence, and the author is one of these. Interestingly though, and correctly, he asserts that progress in this analysis has been made, and he notes that philosophy has joined hands with psychology, artificial intelligence, neuroscience, ethology, and evolutionary theory in making this progress. And this will no doubt continue as advances in these fields are made, and the 21st century will see the advent of the "industrial philosopher". Once thought to be a purely academic profession, the ethical considerations behind genetic engineering and the legal rights of thinking machines will require the presence of philosophers in the rank and file of engineers, technicians, and managers. And because of this, these philosophers, and their coworkers will themselves have considerable knowledge outside their own field. Again, the refreshing feature of this book is that the author believes that philosophy has made considerable process on the nature of mind. This was done, he says, by understanding the mind's self-knowledge, by providing a much clearer idea of the nature of the different theories of mind, and by clarifying the sorts of evidence that must be acquired in order to distinguish between these different theories. Empirical evidence, he states, has enabled the making of these distinctions much more rational and scientific. But he is careful to note that the evidence is still ambigious, and much work still needs to be done before the these ideas can be differentiated with more clarity. He discusses in detail the different theories of dualism and materialism. An entire chapter is devoted to discussing substance dualism, property dualism, philosophical behaviorism, reductive materialism, functionalism, and eliminative materialism. The author asks readers to start anew and throw away their convictions while analyzing these conceptions of mind and matter. For the author, the mind-body problem cannot be solved without considering three problems: 1. Semantical: The meaning of ordinary common-sense terms for mental states. 2. Epistemological: The problem of other minds and the capacity for introspection. 3. Methodological: The proper methodology to use in constructing a theory of mind. Entire chapters are devoted to these, and after reading them the reader entering the debate on the mind-body problem for the first time will have an over-abundance of food for thought. An entire chapter is spent on the topic of artificial intelligence. If this book were updated, this chapter would probably have to be considerably expanded, in that many advances have been made in A.I. since this book was first published. Research in A.I. has been rocky, and many promises that were unfullfilled were made in the past about it. But now it seems a more rational and realistic attitude is taken about the claims of A.I. Most everyone involved in it understands that it is an enormously complex problem, and have concentrated their efforts on building intelligent machines from a piece-meal, microscopic approach, i.e. from solving the simplest problems first before tackling the more difficult ones. A chapter is also devoted to neuroscience. Thanks to imaging technologies and other approaches to mapping the brain, this field has mushroomed in recent years. The author only gives a cursory overview of the brain and the nervous system in this chapter, due no doubt to lack of space. The reverse engineering of the human brain has been pointed to by some researchers in artificial intelligence as being the best hope for building intelligent machines. The dramatic increases in chip technology and bus design have made this belief certainly more feasible. It remains to be seen, via actual empirical research, whether the reverse engineering of the human brain, and then its subsequent implementation in electronic devices, will indeed result in the rise of intelligent machines. Whatever the future of artificial intelligence and neuroscience, the mind-body problem will no doubt be of interest to philosophers for decades to come. It will be fascinating to see what kinds of conceptual frameworks and methodologies will be employed in attempts to solve this problem. Without doubt some new ideas would be welcome in this regard, as proposals for solutions to the mind-body problem seem to be stuck in a local minimum. But, as the author argues well for, the solution will bring in many areas and possibly some radical ideas, all supported by painstaking experimentation.

Extremely accessible introduction, January 27, 2007
"Matter and Consciousness" is a very accessible introduction to basic issues in the philosophy of mind. Paul Churchland divides the book into several sections, with each one serving to give a broad overview of the relevant issues, the main positions and controversies, as well as the major lines of research inquiry that have been developed in the past few decades as ways of approaching the study of brain/mind. The first problem that Churchland addresses in the book is the ontological one - that is, what is the real nature of mental phenomena and in what relation do they stand to the physical world? He surveys the different types of dualism, including substance dualism, property dualism (a category which subsumes epiphenomenalism, interactionist property dualism and elemental property dualism). He also gives a flavor for the many different species of materialism such as reductive materialism/identity theory, functionalism (which currently serves as the main philosophical position for those involved in the fields of cognitive science and artificial intelligence) and eliminative materialism. Some really important questions are addressed in this first section, such as the feasibility of reducing mental states to neurobiological states. The history of science offers plenty of examples of successful intertheoretic reductions - for example, the theory of optics being reduced to the theory of electromagnetism. However, different arguments have been made (not just by dualists, but also by materialists) as to why mental states will not be capable of reduction to neurobiological states. For the functionalists this is because there are no universal correspondences between physical and mental states (there are many potential physical states that can instantiate mental states) and for the eliminative materialists, this is because our current folk psychological framework is radically wrong. Instead of intertheoretic reduction, the eliminative position holds that there will instead be a full-scale elimination, with our folk psychological concepts going the way of phlogiston in the physical sciences. Churchland also focuses on the semantic problem -- where do our mental terms derive their meaning from? He suggests that this problem can be resolved by the network theory of meaning in which the meaning of a term derives from the term's embedded status in a larger theoretical framework. He addresses the epistemological problem (the problem of other minds and the problem of self-consciousness) and the methodological problem. What should be the structure of a science of mind? Churchland reviews several traditional approaches - idealism/phenomenology, methodological behaviorism, the cognitive/computational approach and the methodological materialist approach. In the next two chapters Churchland offers a cursory overview of the fields of artificial intelligence and neurophysiology. These sections are meant to give the reader a flavor of some of the research projects that have been initiated in these fields and the manner in which they bear on the problems discussed in earlier portions of the book. For example, can intelligence be represented computationally? How can we develop programs that simulate aspects of intelligence? Churchland reviews fundamental concepts such as universal Turing machines in a very readable manner. However, it should be noted that Churchland sometimes seems to conflate consciousness and intelligence -- intelligence need not imply consciousness, though he sometimes seems to use these two terms almost interchangeably. The last chapter of the book is devoted to some thoughts on the possible distribution of intelligence in the universe at large. Overall this book should serve as a highly readable introduction to some very difficult problems. Given the amount of the material covered, it is to be expected that many issues will be dealt with in a cursory manner. Some of the author's biases are reflected in the work. However, Churchland does a decent job in trying to present the main arguments and he also provides suggested reading lists at the end of the chapters for those who would want more in-depth coverage.
