David Hodgson Goodbye To Qualia And All That ? Review

Max Bennett is a distinguished Australian neuroscientist, Peter Hacker an Oxford philosopher and leading authority on Wittgenstein. A book resulting from their collaboration, Philosophical Foundations of Neuroscience, has received high praise. According to the Blackwell website, G.H. von Wright asserts that it ‘will certainly, for a long time to come, be the most important contribution to the mind–body problem that there is’; and Sir Anthony Kenny says it ‘shows that the claims made on behalf of cognitive science are ill-founded’.

Much of the book is a development of the claim that most neuroscientists commit this fallacy by attributing to brains properties and activities that can properly be attributed only to persons. I won’t give a general review of the book, which does make valuable points concerning the importance of using language accurately in discussing mental concepts: helpful and laudatory reviews can be found on the Notre Dame Philosophical Reviews website (by Dennis Patterson) and in Philosophy 79, No. 307 (January 2004) 141–6 (by Daniel N. Robinson). However, I believe that some of its basic propositions are themselves fundamentally mistaken, and suggest that this is a consequence of disregard of opposing considerations, and insufficient recognition of the flexibility of language. I will discuss three basic propositions from the book, which are particularly relevant from the ‘consciousness studies’ point of view. The first, my main target, is ‘to see an object is neither to see nor to construct an image of an object’ (p. 141). The other two are closely related: ‘It is mistaken to suppose that the subject of
