The Universal Constant in Living was Alexander’s fourth and last book. It contains his most mature and consummate thoughts on his technique. Alexander shares with the reader knowledge accumulated in the course of more than 45 years of practical teaching experience. Having fully developed the concepts of his technique, he presents a clear exposition of the fundamental principles: prevention (inhibition), the primary control of use, and the unity (wholeness) of the human organism, among others. Written in the turbulent 1930s and completed in the early years of WWII, The Universal Constant in Living makes a great plea for understanding the dangers of separation in the activity of living. Alexander explains how his technique meets the urgent need for wholeness in approach and action. Furthermore, he argues that the practice of his technique provides not only freedom of thought and action, but freedom in thought and action. Alexander also presents testimonies to the practical results and principles of his technique. In an appreciation of Alexander’s work Professor George Coghill, a pioneer of developmental neurophysiology, provides support for Alexander’s concept of a primary control.weiterlesen
