  The dualist might sum up the situation on thought in the following way. The case against physicalist theories of sensation is that it is unbelievable that what it feels like to be struck hard on the nose is itself either just a case of being disposed or caused to engage in certain behaviours, or that what it feels like is not fundamental to the way you do react. Similarly, the dualist about thought will say, when you are, for example, engaged in a philosophical discussion, and you make a response to your interlocutor, it is obvious that you are intending to respond to what you thought he or she meant and are concentrating on what what you intend to say means. It seems as bizarre to say that this is a bye-product of processes to which meaning is irrelevant, as it is to claim the same about sensory consciousness. You are, in other words, as fundamentally a semantically driven engine, as you are a sensorily consciously driven one. Perhaps, in the case of a sophisticated conversation, the fundamentality of meaning, and of conscious reflection, as a driver is even more obvious than in the case of sensation
