I read this for Ken Haase's seminar (Cognitive Theories of Everything), as counterpoint to Minsky's The Society of Mind. Damasio makes the case that "mind" is inseparable from "body", because the chemical and neural environment of the body are vital communication channels of the brain. He offers interesting anecdotes of patients with pre-frontal brain lesions, who have all the traditional requisites for intelligence, but who cannot function normally because injury has made it impossible for emotion to inform their reasoning.
