In States of Equilibrium, John Burton makes a significant contribution to our understandings of the psychology of human learning and development and the structure of personality. In a scholarly and engaging manner Burton integrates the major schools of psychological thought"psychoanalysis, cognitive psychology, humanism, and behavioralism to present a unified theory of personality development and personality disorders. He helps even lay readers to understand the developmental antecedents and underlying dynamics of depression, anxiety, obsessions, and pessimism, as well as those traits that comprise optimism, hope, inner peace, and resilience. He makes excellent use of metaphor and case studies to promote clarity and understanding. His is a coherent theory about how we evolve as conscious beings exercising free will over our emotions. This is a book that should be included in every university psychology curriculum in “theories of personality” courses.
