Once one rejects the interactionist dualism as a theory of the mind, the co
ncept of quale yields a contradiction. Qua phenomenal data of consciousness
it refers to an intrinsic property not explainable in terms of the natural
sciences; qua data of subjective experience a quale is for the subject and
must therefore be functionally efficient. In order to shun this paradox Da
niel Dennett suggests challenging our intuitions concerning consciousness a
nd setting up a new explanatory frame that would make it possible to develo
p a theory without the concept of quale. Though the model defended by Denne
tt presents several difficulties it interestingly represents an invitation
to review the language-games we use to conceive consciousness.
