 Should we include any other mental states on the list? Galen Strawson has claimed (1994) that there are such things as the experience of understanding a sentence, the experience of suddenly thinking of something, of suddenly remembering something, and so on. Moreover, in his view, experiences of these sorts are not reducible to associated sensory experiences and/or images. Strawson’s position here seems to be that thought-experience is a distinctive experience in its own right. He says, for example: “Each sensory modality is an experiential modality, and thought experience (in which understanding-experience may be included) is an experiential modality to be reckoned alongside the other experiential modalities” (p. 196). On Strawson’s view, then, some thoughts have qualia. (This is also the position of Horgan and Tienson (2002).)
