This diverse set of essays traces Epstein's experimental and theoretical work over a 15-year period. Four of the essays were coauthored by the eminent psychologist B.F. Skinner. The book demonstrates how the scientific study of the behavior can increase our understanding and effectiveness in many domains: creativity and innovation, parenting, artificial intelligence, self-improvement, and even world peace. Reviewers have praised the volume as an impressive effort by one of America's most notable psychologists.
