Functionalism serves as an intriguing lens through which to view human behavior, asserting that every aspect of society, from individual actions to cultural norms, exists because it serves a necessary role. This philosophy, originating from the field of sociology, carries significant weight in understanding the interplay between an individual's mind, society, and behavior. The concept of functionalism articulated as a guiding force for behavior, proposed mechanisms, and functionality of societal aspects, has profound implications for the pragmatic applications in everyday life and therapeutic settings.
