This paper introduces Integral Psychology (IP) as a mature embrace to the question of what is human nature and how do we best explore it. Historically, wave after wave of various trends and movements have attempted to give psychology a focus and scientific status. After decades of specialization and segmentation (APA has over 50 divisions), IP aims at a mature synthesis of the field. IP mines and integrates the lasting contributions to our understanding of human nature and potential from all psychological schools of thought, disciplinary divisions, and methods of investigation—paying attention to both research and applications. In this paper I explore six of the major historical predecessors to IP: behaviorism, psychoanalysis, humanistic-existential, transpersonal, constructivist-developmental, and positive psychology.
This article explores how Integral Theory can serve the discipline of psychology in its current, parochial state by offering a framework for unification. While psychology has evolved as a science, the trend toward specialization has rendered it fragmented. Numerous efforts at unification have failed to draw the many specializations together. Until now, no unification theory has offered a sufficiently broad and deep framework to include all aspects of psychology. This paper offers a view of how Integral Theory can serve as a uniting framework for psychology as well as its individual disciplines.
