In the history of thought the relation between the mind and the body has been discussed in terms of various analogies. Plato, for example, examined the analogy of a man and his clothes and of the music of an instrument and the instrument itself; Aristotle advocated the analogy of an instrument's capacity and the instrument itself; Descartes alluded to that of a pilot and his ship; and Ryle derided that of a ghost and a machine.What I wish to discuss, however, (...) are the analogies used by contemporary philosophers to explain their theory that the mind is the brain, that the mind's states, capacities and qualities are the brain's states, capacities and qualities, that our thoughts and our thinking are brain elements and brain movements and that our mental experiences, such as having images or sensations, are brain processes. Various analogies have been advanced to explain the sense in which one of the former is one of the latter. (shrink)

Based on the technique of pressure blinding of the eye, two types of after-image were identified. A physicalist or mind/brain identity explanation was established for a negative a AI produced by moderately intense stimuli. These AI's were shown to be located in the neurons of the retina. An illusory AI of double a grating's spatial frequency was also produced in the same structure and was both prevented from being established and abolished after establishment by pressure blinding, thus showing that the (...) location was not more central. The illusory AI was predicted from the known non-linearity in the retina and this is the first case of a clear cut type-type identity of a sensation and a neural process. Some implications for the concepts of the explanatory gap between neurology and consciousness and multiple neural realizations of conscious states and topic neutrality are discussed. (shrink)

Something is wrong with current discussions about theory reduction. The question of whether higher level theories are reducible to lower level theories cannot be posed in a sensible way if methodological principles that are needed to evaluate scientific theories are disregarded. If this is recognized, the problem looses much of its alleged importance.

Action is to be distinguished from (mere) bodily movement not by reference to an agent's intentions, or his conscious control of his movements (Sect. I), but by reference to the agent as cause of those movements, though this needs to be understood in a way which destroys the alleged distinction between agent-causation and event-causation (Sect. II). It also raises the question of the relation between an agent and his neurophysiology (Sect. III), and eventually the question of the compatibility of purposive (...) and mechanistic accounts of human behaviour (Sect. IV). For the two to be compatible it is necessary that, e.g., intentions and brain states be not merely co-existent but also causal equivalents, in a way which allows for the mechanical explanation of teleological states — or vice versa.

The distinction between mental illness and bodily illness would seem to presuppose some sort of distinction between mind and body. But dualist theories that the mind is a substance separable from the body, or that mental events could occur without any bodily events, raise ancient conceptual problems, which I do not propose to review here. What I want to do is to examine the psychiatric implications of materialist theories, which hold that the mind is the brain, or a function of (...) the brain. If all character has a basis in chemistry, can we still attribute some mental distress to character and some to chemistry, as if the two categories were different? (shrink)

In a recent 5‐to‐4 decision, the Supreme Court of Canada denied to Harvard University a patent on a genetically modified mouse. In their reasoning, the majority Justices, concerned obviously about the implications of granting the patent for the human case, argue that higher organisms (mammals) are not “compositions of matter” in the sense intended by the Canadian Patent Act. But if a mouse is not a composition of matter, what—indeed, what on earth—is it? As the minority Justices complain, the majority (...) decision smacks of dubious metaphysics and theology. Appealing to a quite unlikely source, the Bible, I show that the distinction between mice and men can be defended without introducing problematic metaphysical and question‐begging theological materials. I also show, en route, that the biblical position on the special status of men and women is not inconsistent with evolutionary theory. Granting a patent on the mouse (as was done in the U.S.A.) is compatible with denying it to human organisms. (shrink)

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

To date, there is no universal and coherent theory concerning the nature or the function of time. Furthermore, important and unresolved controversies raging within both philosophy and the natural sciences apparently indicate that there is little hope of constructing a single, unified theory. Even so-called "folk" theories of time, embedded within different cultural traditions, show no common elements, and therefore can not provide a pre-theoretical description of time, towards which an explanatory framework could be constructed. This lack of consensus indicates (...) that the concept as it is currently being used is ill defined, and, at the very least, needs to be considerably revised. The conceptual disarray surrounding time has aided and abetted the arguments of certain thinkers, especially Ricoeur, working within the phenomenological tradition who make de principe claims that there can not be a single theory of time. My intention is not to try and to produce a concept of time that was capable of unifying all these different elements. Rather, Ricoeur's arguments and those of others working in the phenomenological tradition dissatisfied me. I believed that their arguments were informed by a myopic, muddled and positively 19th Century understanding of the scientific project. Hence, my aim is to show that Ricoeur's claim will not stand up to scrutiny, and that there are no principled arguments against the possibility of a unified theory of time. We examine the major arguments against unification in general, and also with particular reference to theories of time, such as Husserlian phenomenology, conventionalism, instrumentalism, anti-reductive positions in general, as well as the specific problem of reducing subjective experience to objective description. We demonstrate that none of these objections constitutes a watertight a priori argument against a unified theory of time. Furthermore, we demonstrate that recent developments in the philosophy of science and the philosophy of mind have made such a unified theory a plausible goal. We argue that post-positivist philosophy of science, with its emphasis on research programmes, the co-evolution of theories and super-empirical rational support, opens the way for new types of evidence to be brought to bear on questions about time. Also, recent developments in the brain sciences mean that a neurologically plausible and fully naturalised analysis of our experience of time is being developed. Although much work in this direction has begun, we argue that it is fragmented, partly through the limitations of our current knowledge, but more particularly through an inadequate background of coherent philosophical thought. This has lead both philosophers and scientists to attempt grand metaphysical answers to muddled philosophical questions which threaten the progress which natural science and the philosophy of science have offered in the second half of the twentieth century.
