Several theorists criticize the unacknowledged assumptions of mainstream psychology, calling for a new philosophical foundation to better serve the study of persons. This article responds by offering a metatheory for psychology that contributes criteria for evaluating knowledge claims and also accommodates multiple worldviews, audiences, and purposes. Beginning with the presumably noncontroversial contention that psychological inquiry is a human activity (Osbeck, 2019; Westerman, 2004), the assumptions necessary for any human activity are explicated. I will refer to them as the “view from humanity,” as this term reflects both the perspectival nature of knowledge (i.e., a “view”) and the necessity of these assumptions for all functioning humans. Emerging from the view from humanity, and consistent with other outlooks on psychology as a social activity or practice, are “Inquiry Architectures” for examining and situating diverse theoretical perspectives. A psychology that is maximally pluralistic while at the same time constrained by universally accepted assumptions accommodates broad psychological understandings and fosters multicultural endeavors to address global challenges.
