3 Thus Dennis and Melzack: ‘The appropriate behavioural response to overt damage may be inactivity; pain arising from trauma should presumably promote such behaviour. However, the appropriate behavioural response to threat may be vigorous activity; pain arising from threat should therefore promote this sort of activity. Thus the overt expression of pain sensation may actually be a combination of inherently contradictory processes and behavioural tendencies.’ Dennis, S. and Melzack, R., ‘Perspectives on Phylogenetic Evolution of Pain Expression’, Animal Pain: Perception and Alleviation, Kitchell, R. L. and Erickson, H. H. (eds), (Bethesda: American Physiological Society, 1983), 155.

5 Thus Theodore Barber reports of individuals chronically insensitive to pain that for most, if not all, ‘no distinct localized damage exists in the central nervous system’. ‘Toward a Theory of Pain’, Psychological Bulletin 56 (1959), 443. It is true that Barber cites no evidence from autopsies, and that more sophisticated scanning apparatus has been developed since this publication, but the fact that this insensitivity to pain can be reversed without surgical intervention would support Barber's observation.

13 Colin McGinn has made a similar point from a different perspective. He argues that the mystery of our mental life arises out of the fact that we simply do not possess the cognitive faculties necessary to solve the mind-body problem. ‘Cognitive closure’ prevents our ever having access to that vital natural link which presumably exists between brain states and conscious states. See McGinn, Colin, ‘Can We Solve the Mind-Body Problem?’, Mind 98 (1989), 349–366.

16 Quoted in Boakes, Robert, From Darwin to Behaviourism (Cambridge University Press, 1984), 40. This dictum is actually a version of the Aristotelian principle, ‘Nature does nothing in vain’, couched in evolutionary terms.
18 Descartes' clearest explanation of the matter comes in a letter to the English Platonist, Henry More. See Descartes, , Philosophical Letters, Kenny, Anthony (ed.), (Oxford: Clarendon Press, 1970), 243–245.
19 It may seem that Morgan and Descartes are making the same point, but they are not. Morgan's canon was virtually a biological application of the second law of thermodynamics, asserting that a complex biological system would not evolve if a simpler one could perform the same function. Of course, in applying this canon to ‘psychical’ functions, Morgan seems to have committed himself to the view that more complex mental states require a more complex physical apparatus.
20 Thus Descartes admitted in his letter to More that his thesis about animals was only probable. Philosophical Letters, 244.
