‘Let us not forget this: when “I raise my arm”;, my arm goes up. And the problem arises: what is left over if I subtract the fact that my arm goes up from that fact that I raise my arm?’

page 354 note 2 Thus John Ladd, in ‘Freewill and Voluntary Action’, Philosophy and Phenomenological Research, 1951/1952, writes: ‘A person who has had a limb amputated may unsuccessfully will to move the absent limb. Still he has done something, if it only be having had the appropriate imagery and discharging nervous energy into the formerly appropriate nerves.’

page 354 note 4 If this sort of willing were to have effect it would constitute a case of what paranormal psychologists call ‘psycho-kinesis’. It has been maintained by Professor J. C. Eccles, in Nature, 1951, pp. 53–57, and The Neurophysiological Basis of Mind, pp. 284–285, that such psycho-kinesis may well be the explanation of the effect of mind on brain in voluntary action. For a discussion of the idea that voluntary action is like willing other people to do things, see B.ÓShaughnessy, ‘The Limits of the Will’, Philosophical Review, 1956.

page 358 note 2 For a revival of this theory see Professor Campbell, C. A., ‘Self-activity and its modes’, in Contemporary British Philosophy, Third Series, p. 93. Campbell holds that if a person has somehow forgotten what are the specific sensations associated with moving his leg, he cannot will to move it. His ground for this belief is his conviction, based on introspection, ‘that the immediate object of our willing is not the movement of our leg but certain kinaesthetic and other sensations upon which, we have learned from experience, the movement of our leg normally supervenes’.Google Scholar

page 364 note 2 For example, Eccles, J. C., The Neurophysiologiccd Basis of Mind, p. 272: ‘The principal grounds for the theoretical belief that voluntary control of actions is an illusion are derived from the assumptions that science gives a deterministic explanation of all natural phenomena and that we are entirely within this deterministic scheme. In this context reference may be made to the recent discussion by Popper (Brit. Joum. Phil. Sci., 1950, pp. 117–33, 173–95), in which he concludes that not only quantum physics but even “classical mechanics is not deterministic, but must admit the existence of unpredictable events”. There are thus no sound scientific grounds for denying the freedom of the will, which virtually must be assumed if we are to actas scientific investigators.’Google Scholar
