Humanistic psychology

Most psychologists before him had been concerned with the abnormal and the ill. He urged people to acknowledge their basic needs before addressing higher needs and ultimately self-actualization. He wanted to know what constituted positive mental health. Humanistic psychology gave rise to several different therapies, all guided by the idea that people possess the inner resources for growth and healing and that the point of therapy is to help remove obstacles to individuals' achieving them. The most famous of these was client-centered therapy developed by Carl Rogers.

The basic principles behind humanistic psychology are simple:

Humanistic psychology theory suits people who see the positive side of humanity and believe in free will. This theory clearly contrasts with Freud's theory of biological determinism. Another significant strength is that humanistic psychology theory is compatible with other schools of thought. Maslow's hierarchy is also applicable to other topics, such as finance, economics, or even in history or criminology. Humanist psychology, also coined positive psychology, is criticized for its lack of empirical validation and therefore its lack of usefulness in treating specific problems. It may also fail to help or diagnose people who have severe mental disorders. Humanistic psychologists believe that every person has a strong desire to realize their full potential, to reach a level of " self-actualization ". The main point of that new movement, that reached its peak in 1960s, was to emphasize the positive potential of human beings. Maslow positioned his work as a vital complement to that of Freud:

It is as if Freud supplied us the sick half of psychology and we must now fill it out with the healthy half.

However, Maslow was highly critical of Freud, since humanistic psychologists did not recognize spirituality as a navigation for our behaviors.

To prove that humans are not blindly reacting to situations, but trying to accomplish something greater, Maslow studied mentally healthy individuals instead of people with serious psychological issues. He focused on self-actualizing people. Self-actualizing people indicate a coherent personality syndrome and represent optimal psychological health and functioning.

This informed his theory that a person enjoys " peak experiences ", high points in life when the individual is in harmony with themself and their surroundings. In Maslow's view, self-actualized people can have many peak experiences throughout a day while others have those experiences less frequently. He believed that psychedelic drugs like LSD and psilocybin can produce peak experiences in the right people under the right circumstances.
