  Quoting these passages, David Chalmers (1996, p. 360) objects that if ‘something is going on’ is construed broadly enough it is inadequate, and if it is construed narrowly enough to cover only experiential states (or processes) it is not sufficient for the conclusion. Smart would counter this by stressing the word ‘typically’. Of course a lot of things go on in me when I have a yellow after image (for example my heart is pumping blood through my brain). However they do not typically go on then: they go on at other times too. Against Place Chalmers says that the word ‘experience’ is unanalysed and so Place's analysis is insufficient towards establishing an identity between sensations and brain processes. As against Smart he says that leaving the word ‘experience’ out of the analysis renders it inadequate. That is, he does not accept the ‘topic-neutral’ analysis. Smart hopes, and Chalmers denies, that the account in terms of ‘typically of’ saves the topic-neutral analysis. In defence of Place one might perhaps say that it is not clear that the word ‘experience’ cannot be given a topic neutral analysis, perhaps building on Farrell (1950). If we do not need the word ‘experience’ neither do we need the word ‘mental’. Rosenthal (1994) complains (against the identity theorist) that experiences have some characteristically mental properties, and that ‘We inevitably lose the distinctively mental if we construe these properties as neither physical nor mental’. Of course to be topic neutral is to be able to be both physical and mental, just as arithmetic is. There is no need for the word ‘mental’ itself to occur in the topic neutral formula. ‘Mental’, as Ryle (1949) suggests, in its ordinary use is a rather grab-bag term, ‘mental arithmetic’, ‘mental illness’, etc. with which an identity theorist finds no trouble.
