'Mole brings complexity theory, the philosophy of mind, and the metaphysics of dynamic processes together into a compelling analysis of human intelligence. The book is a pleasure to read, with its web of complex arguments made transparent by the clarity of the writing. It is essential reading for anyone tempted to think traditional cognitive science can explain intelligence.' - Rowland Stout, University College Dublin, Ireland'Mole’s discussion of the computational complexity that the exercise of intelligence must confront, and his search for a solution in the intelligent agent’s engagement with the world and other agents, offers a striking new approach to understanding what makes human beings so smart.' - Lawrence Shapiro, University of Wisconsin-Madison, USA
