The Science of MAN:
The Fourth Way School of Dr. Bob Gibson

Dr. Bob Rhondell Gibson

In the late 1980’s, Dr. Robert (“Dr. Bob”) Rhondell Gibson produced The Science of Man school program as a series of 48 weekly lessons on audio cassette tapes for students unable to participate in live groups. This lesson series, also referred to as “The 48-Weeks” or “The 48-Tapes”, has been a launching point for discovery and liberation for generations of students.


Although the audio cassettes were originally designed for use by independent students, the program has also been a teaching foundation for numerous study groups focused on the work of self-knowing.


Those familiar with the teachings of G.I. Gurdjieff and J. Krishnamurti will recognize some familiar ideas and spiritual work approach—objective self-observation as a process of exposing the operations of the conditioned self, purifying perception, and disidentification from the ego. Beyond those shared principles, Rhondell’s Science of Man is a unique expression of the Great Teaching, universally regarded by students as accessible, direct, and complete as a school of spiritual work.
