Reading these essays has shown me a great deal, both about the substantive issues I have dealt with and about how to do philosophy. On the former front, they show that I have missed some points and overstated others, and sometimes just been unable to penetrate the fog. On the latter front, they show how hard it is to write philosophy that works--and this is the point that stands out for me as I reflect on these rich and varied essays. (...) Philosophical books and articles routinely fail to achieve their manifest goal of persuading their intended audiences of their main points. Does this make philosophy any worse off than other writing endeavors? Most published novels are failures of one sort or another, and the press has reported a recent study (whose methodology I wonder about) that concludes that the median number of readers of any paper published in a psychology journal is zero. But it seems to me that philosophy displays a particularly feckless record, with such a huge gap between authorial pretense and effect achieved that it is perhaps more comic than pathetic. In one weak moment I found myself thinking that perhaps some of our French colleagues have the right idea: deliberate obscurantism and the striking of stylized poses--since the goal of persuading by clear, precise analysis and argument is so manifestly beyond us. But that worldly weariness passed, I'm happy to say, and my cock-eyed American optimism returned. My ambition continues to be to change people's minds, and not just to win people over to my way of doing philosophy, as Bo Dahlbom suggests. But I admit that it is harder than I had thought. It's hard enough to get a good idea, but sometimes it's even harder, apparently, to get others to see what the idea is, and why it's good. (shrink)

The central mission of cognitive science is to reveal the real nature of the mind, however familiar or foreign that nature may be to naive preconceptions. The existence of naive conceptions is also important, however. Prescientific thought and language contain concepts of the mental, and these concepts deserve attention from cognitive science. Just as scientific psychology studies folk physics (McCloskey 1983, Hayes 1985), viz., the common understanding (or misunderstanding) of physical phenomena, so it must study folk psychology, the common understanding (...) of mental states. This subfield of scientific psychology is what I mean by the phrase 'the psychology of folk psychology'. (shrink)

Cognitive science has wholeheartedly embraced functional brain imaging, but introspective data are still eschewed to the extent that it runs against standard practice to engage in the systematic collection of introspective reports. However, in the case of executive processes associated with prefrontal cortex, imaging has made limited progress, whereas introspective methods have considerable unfulfilled potential. We argue for a re-evaluation of the standard ‘cognitive mapping’ paradigm, emphasizing the use of retrospective reports alongside behavioural and brain imaging techniques. Using all three (...) sources of evidence can compensate for their individual limitations, and so triangulate on higher cognitive processes. (shrink)

Criticizes R. E. Nisbett and T. D. Wilson's counterintuitive argument on theoretical and methodological grounds. It is suggested that inappropriate statistical tests were used and that their argument was stated in a nonfalsifiable position. In addition, it is also argued that causality was incorrectly defined, other essential definitions were missing, and that other evidence opposes their theory.

During the last decades, the enigmatic field of volition has been the object of quantitative brain mapping studies. In this essay, emphasis will be given to brain mapping observations during overt or imagined willed acts in conscious normal individuals. The findings suggest that such acts are ‘formulated’ in the frontal/prefrontal cortex as neuronal programs for future motor, behavioural, verbal, or cognitive acts. During imagined movements or speech, brain mapping reveals important prefrontal activations which contrast to perirolandic activations during overt willed (...) acts. In psychiatric disorders with symptoms of a ‘sick will', like in schizophrenia, affective disorders, and organic dementia, reductions of the resting prefrontal activity have been recorded. The relationship between will and prefrontal activity is compatible with the view that frontal/prefrontal parts of the cortex are involved in the serial temporal programming of motor behaviour, speech, and cognition. In addition, there are unconscious mechanisms participating in volition. Electrophysiological evidence presented by Libet supports this view. (shrink)
