The 1960s were troubled times in the United States, and a group of psychologists emerged who believed that behaviorism and psychoanalysis, the two major forces in psychology at the time, were neglecting important aspects of human existence. What was needed was a third force that emphasized the positive, creative, and emotional side of humans. This third-force psychology is a combination of existential philosophy and romantic notions of humans; the combination is called humanistic psychology, as well as third-force psychology. Humanistic psychologists are phenomenologists. In modern times, Brentano and Husserl developed phenomenology, which is the study of intact, conscious experiences as they occur and without any preconceived notions about the nature of those experiences. According to Brentano, all conscious acts intend (refer to) something outside themselves. An example is the statement “I see that girl.” Husserl thought that a careful, objective study of mental phenomena could provide a bridge between philosophy and science. Besides the type of phenomenology that focuses on intentionality, Husserl proposed a second type, a pure phenomenology that studies the essence of subjective experience. Thus, for Husserl, phenomenology could study the mind turned outward or turned inward.
