Maslow defines psychologist as “all sorts of people, not just professors of psychology.” He says “(By psychologists,) I mean to include all the people who are interested in developing a truer, a cleaner, a more empirical conception of human nature, and only such people. That excludes many professors of psychology and psychiatrists. That would include some sociologists, anthropologists, educators, philosophers, artists, publicists, linguists, and businessmen – anybody who is pointed in this direction; practically anybody who has taken upon his own shoulders this task that I consider so great and so important.
Humanistic psychology is primarily an orientation toward the whole of psychology rather than a distinct area or school. William James and G. Stanly Hall advocate such a psychology that would leave the wholeness, passion, and uniqueness of the individual intact.
The essential themes of humanistic psychology are (1) an emphasis on conscious experience, (2) a belief in the wholeness of human nature and conduct, (3) a focus on free will, spontaneity, and the creative power of individual, and (4) the study of everything that is relevant to human condition.
