Although the injunction "Know thyself" was inscribed over the site of
the Delphic Oracle, the concept is of much more ancient lineage.
Thousands of years ago, the wise men of the East had learned to exert
authority over a broad range of bodily experiences and functions using
techniques that are still taught today. But it is only in the past few
decades that the West has become aware once again of the range of
control that the central nervous system can maintain over sensation and
body function. Medicine has moved slowly in integrating these concepts
into the classic medical model of disease despite a growing body of
evidence that links emotional state, thought, and imagery to
immunocompetence, tissue healing, and bodily vigor. It is precisely the
role of a volume such as this, reflecting a fascinating conference in
Munich, to emphasize and reemphasize these ideas. We are fortunately
well beyond the sterile behaviorism of Watson with its com- plete
negation of the significance of mental operations. But many still
consider suspect those forces and mechanisms, however powerful, that
seem to originate from brain-mind activity. The chapters in this book,
with their emphases on the mind-body continuum as a bridge to self-
regulation and health, provide a modern "School of Athens" in bringing
these concepts to wider acquaintance.
