On a day like any other, all mammals suddenly gain human-level consciousness-and begin a systematic attack on human kind. Among the ranks of these animals are a bear in the Canadian Rockies, an elephant in a traveling circus in Texas, a pig on a hog farm in North Carolina, and a dog living with his beloved owner in New York. As these four contend with the realities of who they were before the awareness, and who they must now become after it, they are each called to battle. The animals must then fight two wars: the one outside between mammals and humans, and the one inside each of their minds.

This book deploys the mathematical axioms of modern rational mechanics to understand minds as mechanical systems that exhibit actual, not metaphorical, forces, inertia, and motion. Using precise mental models developed in artificial intelligence the author analyzes motivation, attention, reasoning, learning, and communication in mechanical terms. These analyses provide psychology and economics with new characterizations of bounded rationality; provide mechanics with new types of materials exhibiting the constitutive kinematic and dynamic properties characteristic of different kinds of minds; and provide philosophy with a rigorous theory of hybrid systems combining discrete and continuous mechanical quantities. The resulting mechanical reintegration of the physical sciences that characterize human bodies and the mental sciences that characterize human minds opens traditional philosophical and modern computational questions to new paths of technical analysis.
