The metaphorical Beast concept was introduced in The Small Book to help actively addicted persons transcend the chains of addiction and achieve no-higher-power (NHP) sobriety. Addictive Voice Recognition Technique® (AVRT®) is the discipline that very quickly evolved from its use in self-help groups and from my own clinical practice. In 1992, the Beast metaphor was presented in the context of what I call the structural model of addiction, referring to the origins of the Addictive Voice in the animal-like midbrain, and building a dichotomy based upon the functional differentiation of brain tissues. Subsequently, Rational Recovery has built a better theoretical mousetrap than the medical and psychological disease models.
