Wilhelm Reich developed ideas that Freud had developed at the beginning of his psychoanalytic investigation but then superseded but never finally discarded. These were the concept of the Actualneurosis and a theory of anxiety based upon the idea of dammed-up libido. In Freud's original view, what really happened to a person (the "actual") determined the resulting neurotic disposition. Freud applied that idea both to infants and to adults. In the former case, seductions were sought as the causes of later neuroses and in the latter incomplete sexual release. Unlike Freud, Reich retained the idea that actual experience, especially sexual experience, was of key significance. By the 1920s, Reich had "taken Freud's original ideas about sexual release to the point of specifying the orgasm as the criteria of healthy function." Reich was also "developing his ideas about character into a form that would later take shape, first as "muscular armour", and eventually as a transducer of universal biological energy, the "orgone"."
