Entire hemispheres can be excised without abolishing waking consciousness. The task of a theoretician in this kind of work is to find just those critical facts that help to cast some light on the mechanisms of whatever topic we are investigating, whether consciousness or emotion. The theoretical inferences made in this process must not be overstated, or they will be useless. But they cannot be understated either. Precision, care, and empirical grounding is essential.
All claims are provisional.
What worries me a bit about Doug's remarkable integration of the brain literature on emotion is a lack of specificity and boundedness. Emotion appears to include everything. Now these statements are not false, exactly. There is an argument to be made for all of them. But they are imprecise and their conditions for empirical testing are unclear.
