With grand, inclusive theories of psychology such as Freud´s now largely discredited, psychological enquiry is focused more narrowly and empirically. This book aims to change the status quo and offer a new, redefining and unified theory of psychology.

Concern about psychology´s fragmentation is not new, but there has for the past decade been increasing calls for psychologists to acknowledge to the costs associated with fragmentation and to search for ways to unify the discipline.

A New Unified Theory of Psychology introduces a new system that addresses psychology´s current theoretical and philosophical difficulties. The new theory consists of four interlocking pieces that together provide-for the first time-a macro-level view that clarifies the nature of psychology´s problems and offers a clear way to unify the various elements of the field. The unified theory provides the field of psychology with a well-defined subject matter, allowing both academic and professional psychologists will be able to develop a shared language and conceptual foundation.

Dr. Gregg Henriques is Associate Professor and Director of the Combined-Integrated Doctoral Program in Clinical and School Psychology at James Madison University. He received his Masters degree in Clinical/Community Psychology from the University of North Carolina-Charlotte in 1996 and his Ph.D. in Clinical Psychology at the University of Vermont in 1999. Prior to coming to JMU in 2003, he spent four years at the University of Pennsylvania where he worked with Dr. Aaron T. Beck, exploring the effectiveness of psychotherapy for individuals who recently attempted suicide.

Dr. Henriques has been working on the Tree of Knowledge System for just over a decade. During his Masters degree, he had become interested in the field of psychotherapy integration and began surveying diverse bodies of literature. It was late in 1996, while he was reading up on research in social cognitive theory, evolutionary psychology and psychodynamic theory that he had the key insight that led to the Justification Hypothesis. Six months after that pivotal idea, he had developed the basic structure of the Tree of Knowledge System.
