The theory of orgone is the culmination of Wilhelm Reich's scientific research and the connecting link of his entire work. Contrary to the usual way of presenting his research, which he adopts in his work "The Discovery of the Orgone" (Volume I, "The Function of the Orgasm" and Volume II, "The Biopathy of Cancer"), and in other studies, here he completely changes tactics and invents a fantastic scientific debate with a physicist specializing in the theory of electromagnetism, in order to help us understand the physics of orgone and its relationship with electromagnetism, heat, and magnetism. The physical properties of orgone - that is, of primordial cosmic energy - and the exploration of its nature as a physical entity, are presented in the pages of the book vividly and effortlessly as a friendly exchange of views between two scientists, where one is a supporter of established physics, while the other proposes new physical discoveries accompanied by innovative concepts. The result is a highly interesting and informative description of the research that led Reich to the discovery of orgone, including the mistakes he made, the dead ends he encountered, and the analysis of the elements through which he arrived at the conclusions and substantiation of the theory of orgone.
