Since its formulation by George Kelly in the mid-1950s Personal Construct Psychology has been distinguished by its links with general philosophy and by the philosophical richness of its fundamental postulates. Personal Construct Psychology recognises that any attempt to understand why we behave as we do must begin with an understanding of how we create meaning. After a brief general introduction Bill Warren traces the philosophical history of Personal Construct Psychology through the broad and complex tradition of phenomenology and thinkers such as Spinoza, Hegel and Heidegger. He also gives credit to the influence of general creative and dramatic literature across a variety of cultures. Specific issues addressed in depth include the position of Personal Construct Psychology with regard to philosophy of science, cognitive science, clinical psychology, concepts of mental illness and the implications for social and political philosophy. Philosophical Dimensions of Personal Construct Psychology will provide counsellors, therapists and students of Personal Construct Psychology with a broader appreciation of its historical and philosophical context and its importance to contemporary psychology.
