Modern psychology is mostly a riddle. To tackle it, psychologists have advanced seven different schools about the mind. These are (1) Functionalism that studies the mind as an information processor, (2) Behaviorism that studies the mind through its behaviors, (3) Constructivism that studies the mind as a meaning-making instrument, (4) Emotivism that gives priority to emotions in governing behavior, (5) Structuralism that sees common structures across human minds, (6) Intentionalism that focuses on the drive toward self-actualization, and (7) Psychoanalysis that studies the unconscious. Each of these is partially true of the mind, and yet, there is no method to integrate them into a single theory. Collectively, they constitute incomplete and inconsistent theories of the mind. In this course, we will discuss these seven approaches and reconcile them through a model that sees them as different aspects of a person.
