This paper introduces the concept of behavioral philosophy, discusses its relationship to philosophical counseling and psychotherapy, and focuses on the concept of normalcy as the normative foundation for a broader discussion on pathology versus philosophical dysfunctionality in life. Following the starting definitions, the argument proceeds to considering how normalcy as a normative foundation of both behavioral philosophy and philosophical counseling and of psychotherapy (along with pathology and pathologization) plays a role in the perspective of behavioral self-improvement sought by behavioral philosophy and by psychotherapy (for various reasons, depending on the psychotherapeutic school and methodology). The author concludes that normalcy, rather than pathology or mental disorder, is the focal concept to discuss in order to understand the role of spirituality and spiritual conviction and belief within the context of therapeutic change, whether it is interpreted philosophically or strictly psychotherapeutically.
