Radionics is defined as a method of diagnosis and therapy which is primarily concerned with the utilization of subtle force fields and energies, for the purpose of investigating and combating the causes of disease which ravage humanity and the other kingdoms of nature. But in examining the history and development of radionics from the pioneering work of Dr Albert Abrams and Ruth Drown to the latest experimental work at the de la Warr Laboratories, David Tansley discovered a curious paradox. In literature on the subject, and in the rate books which provide the very core of radionic thera- peutic measures, there are plenty of references to man`s physical organic systems, but little regarding the probability of underlying force fields which might govern and determine the health of the physical form. This book represents an informed endeavour to redress the balance by providing a simple yet practical outline of the subtle anatomy of man. The theory is not new: Abrams diagnosed at a distance, and Drown treated absent patients. David Tansley believes that the time is ripe for radionics to bear witness to an energy field of a more subtle nature: that this is, in fact, its innate purpose.
