Abstract. This introductory chapter was written in 1996, for a new book of review articles on the emerging science of consciousness, specifically aimed at undergraduate and postgraduate students by experts in the relevant fields. Following on a brief history, the chapter moves on to definitions of consciousness and background philosophical issues, and then introduces a unified, non-reductionist scientific approach. It then summarises major issues for studies of consciousness in cognitive psychology, including studies of attention, memory, the extent of preconscious analysis (...) and the relation of consciousness more generally to human information processing. It then turns to the neuropsychology of consciousness, starting with some apparent neural requirements for the transition from preconscious to conscious states, various clinical dissociations of consciousness, conditions for integration (or binding) and, finally, clinical applications, including different forms of mind/body interaction and evidence for the causal efficacy of mental states. The chapter concludes that while some of the ancient problems of consciousness remain unsolved, its study has become the subject of a rapidly developing science. (shrink)

Stefan Sorgner (2009) says that on becoming familiar with transhumanism, he “immediately thought that there were many fundamental similarities between transhumanism and Nietzsche’s philosophy, especially concerning the concept of the posthuman and that of Nietzsche’s overhuman.” In contrast to Bostrom (2005), Sorgner sees significant and fundamental similarities between the posthuman and the overhuman. (I will adopt his use of “overhuman” in place of “overman” or Übermensch.) This overall view seems to me highly plausible. I agree with most of Sorgner’s comments (...) in this respect. My intent is to give further support to the conceptual parallels. In addition, I argue that these are not merely parallels: transhumanist ideas were directly influenced by Nietzsche. (shrink)

Within psychology and the brain sciences, the study of consciousness and its relation to human information processing is once more a focus for productive research. However, some ancient puzzles about the nature of consciousness appear to be resistant to current empirical investigations, suggesting the need for a fundamentally different approach. In Velmans I have argued that functional accounts of the mind do not `contain' consciousness within their workings. Investigations of information processing are not investigations of consciousness as such. Given this, (...) first-person investigations of experience need to be related nonreductively to third-person investigations of processing. For example, conscious contents may be related to neural/physical representations via a dual-aspect theory of information. Chalmers arrives at similar conclusions. But there are also theoretical differences. Unlike Chalmers I argue for the use of neutral information processing language for functional accounts rather than the term `awareness'. I do not agree that functionalctional equivalence cannot be extricated from phenomenal equivalence, and suggest a hypothetical experiment for doing so - using a cortical implant for blindsight. I argue that not all information has phenomenal accompaniments, and introduce a different form of dual-aspect theory involving `psychological complementarity'. I also suggest that the hard problem posed by `qualia' has its origin in a misdescription of everyday experience implicit in dualism. (shrink)

Philosophical critics standardly read behaviorism as a program for defining the concepts of folk psychology in equivalent behavioral terms. This is a misreading. Behaviorism is a program for getting rid of ill-defined mentalistic terms in favor of better defined behavioral idiom. In short, it is a program not for conceptual analysis but for verbal reform. Therefore, criticizing behaviorists for failing to define mentalistic concepts is like criticizing opponents of the Spanish Inquisition for failing to define witchcraft.

There are many reasons to assume that the contents expressible by declarative sentences are generally truth-evaluable. This assumption of global truth-evaluability, however, appears to conflict with the view that the contents of some sentences do not admit of truth or falsehood for lack of objectivity of their subject matter. Could there be a notion of truth on which the truth-evaluability of a content does not rule out the non-objectivity of its subject matter?In this paper, I discuss Crispin Wright's criterion of (...) Cognitive Command as a criterion for objectivity. This criterion faces the Problem of A Priori Error. I reject Wright's response to that problem and propose to solve the problem by relativising truth. This move allows for the possibility of contents that are truth-evaluable yet non-objective.

It is controversial whether a property can both be dispositional and causally efficacious. Mackie and Armstrong hold that dispositions can be causes, Prior, Pargetter and Jackson argue that they cannot. However, all parties of the debate agree on two ideas: 1) The dispositional properties at issue are macroscopic, and in principle reducible to a microscopic reduction base. 2) Only the microphysical base properties are causally efficacious. The disagreement is about whether the macroscopic disposition inherits this efficacy by being identical to (...) its reduction base (Armstrong) or is epiphenomenal because not identical to its reduction base (Prior, Pargetter and Jackson). I challenge thesis 2, which seems plausible only if one conflates two senses of the word “basis” that can be clearly distinguished thanks to the predicate/property distinction. I show that the categorical basis of a disposition need not be its microscopic reduction basis. This allows me to defend the idea that macroscopic dispositional properties can be distinct from their microscopic base properties and nevertheless efficacious. Part of the importance of this topic lies in its bearing on the nature of mental properties: If I am correct about macroscopic dispositions in general, it becomes plausible to argue that mental properties of a subject are dispositional properties which are nevertheless causally efficacious for the subject's actions.

Nor does the converse relation hold. Freedom does not insure facility, as the following case shows. Jones is free, any time he wishes, to press five hundred pounds. There is no law against it and nobody will object if he makes the attempt. Nevertheless, Jones, who weighs only a hundred pounds himself, is unable to lift fifty pounds, much less five hundred, and must fail if he tries. Again, the distinction is that between "may" and "can." Jones may lift five (...) hundred pounds; he can't. He has the prerogative but not the power; he has the right but not the strength. (shrink)
