Ken Wilber is today considered one of the most influential representatives of transpersonal psychology, which arose about 30 years ago. His integral approach attempts a coordinated unification of almost all areas of knowledge from physics and biology, systems theory and chaos theory, art, poetry and aesthetics, to all significant schools and areas of anthropology, psychology and psychotherapy, the great spiritual and religious traditions of the East and West. Wilber's intellectual and spiritual vision offers new possibilities for relating and developing a wide variety of research projects.
