The authors argue throughout the book for the usefulness of autonomous agents (robots) to understand intelligence (as embodied IQ, citing Edelman and Fuster but oddly omitting McCulloch ) and all other aspects of mind. At the book’s end, however, having considered communication between humans and robots (such as Koboyashi’s facial expression robots), the authors conclude that "without going into detail, what we can say at first consideration is that because of their different sensory-motor and physical setup, robots will have emotions of a completely different nature than human emotions" (p. 642) and will be evaluated by a Turing test. Although this is admirably respectful of William Cannon and the origin of human emotions in body organs, emotions are singled out unnecessarily. All models of natural sensory-motor phenomena will differ from the biological, but this is not the point. It is from the underlying logic, the dynamisms and discernible quanta, even of emotions, that we shall learn.
