"Just so we're clear, she said, I know the rules of confession. What I say cannot be repeated. Not to anyone..."

When Mack O'Brien left his home in Port Talbot for the seminary as a teenager, he didn't imagine he'd be back a decade later, unordained and still at a loss as to what makes for a moral life. He takes a job as a security guard at the local steelworks and begins an uneasy transition into the world he once rejected. When the men of the steelworks organise an unprecedented strike in protest against job cuts, he sees no reason not to go along with it.

The last person Mack expects to see in the local club is Siwan Roderick - the woman who appeared out of the blue at the seminary one day to make a confession and swear him to secrecy. Mack kept his word.

But as the day of the strike nears, and as he begins to fully understand what Siwan is planning, Mack is forced to reckon with his loyalty to her and the question of whether an act of violence can ever be justified.

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.

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.
