Much of the legal and social interest in new neuroimaging techniques stems from the belief that they can deliver on the materialist understanding of the relationship between the brain and the mind. This article looks at predictions about the future both of scientific advances and of social reactions to those predictions. It looks at the likely technical limits on neuroscience-based mindreading, then at the likely limits in how the law might use such technologies. It describes three kinds of technical barriers (...) to detailed and useful mindreading: the likely impossibility of making a complete and accurate model of a human brain in light of its incredible complexity, the problems of interpersonal and intrapersonal plasticity, and the problem of trying to read, now, someone's past mental state. The potential changes to the operation of the law, through the use of mindreading as evidence of pain, deception, or bias, among other things, could be extremely important. (shrink)

The justification of a wholly non-Humean conceptual scheme, based upon the idea of enduring individuals with powers, rests in part on the success of such a scheme in resolving the problems bequeathed to us by the Humean tradition and in part must be achieved by a careful construction of the metaphysics of the new scheme itself. By this we mean a thorough exposition of the meaning and interrelations of the concepts of the new scheme. It is to the latter task (...) that we turn in this paper, being satisfied that the power of the scheme to give a rational account of science has been shown, and that its effectiveness in resolving the Humean problems and dilemmas has been amply demonstrated.
