Criticism from other profiles, close to the field, also include the observations of Ken Wilber and Jorge Ferrer. Wilber, one of the early profiles within the transpersonal field, has repeatedly announced the demise of transpersonal psychology. However, the early transpersonal theory of Wilber was itself subject to criticism, most notably from humanistic psychologists Rollo May and Kirk Schneider. Even though Wilber has distanced himself from transpersonal psychology in favour of integral philosophy, his transpersonal model has continued to attract both recognition and criticism.
