"I agree that the qualitative experience is not the key to understanding intelligence from a scientist's point of view. The scientifically tractable aspect of consciousness is not the fact that there are people or animals subjectively experiencing it, but the fact that some kinds of information are mutually accessible and others are not, and that there is therefore a portion of mental information processing that has a different status than the rest of it. That's one sense of consciousness: information that's accessible to a particular body of information-processing involved with the current environment, and which in humans can interface with the verbal apparatus." 3rd culture.
