The absence of a philosophical system that can effectively address the profound problems that exist at the heart of psychology has resulted in the discipline becoming increasingly defined and unified simply by its commitment to the scientific method. This article articulates why unification via method is a weak intellectual solution and explains how the Unified Theory (Henriques, 2011) provides the needed framework so that the field can evolve from its current unity via method to a more mature conceptual unity that clearly defines psychology, grounds it in a scientific worldview, and assimilates and integrates its key insights into a coherent whole.
