This book is the first in-depth effort to explain an emerging therapeutic approach known as the Method of Levels which is based specifically on Perceptual Control Theory (PCT). In his foreward to the book, William T. Powers, the originator of PCT, explains: "The basic idea behind PCT is that organisms act to control a world presented to them as perceptions, rather than reacting to stimuli or planning their action or being conditioned or any of those other ideas that have been proposed since before I was born." The book includes two DVDs, one which includes introductions to PCT, tutorials, simulations, articles, and links; and another which includes actual MOL sessions. [Living Control Systems Publishing]
