The book defines intuitive intelligence and creativity (intu-creativity); describes why its use is imperative beyond the narrow limits of science and logic; and examines its "anatomy," evolution (in the species), personal determinants, and "metabolism." It provides the basis for the measurement of its capacity, consisting of 20 skills. It describes the areas of human endeavors most sensitive to its application, viz human relationships of all kinds. It further describes how it matures and how it can go wrong. Having provided the reader with the author's most up-to-date research and findings, the book goes on to describe how managers, entrepreneurs making decisions, and all ultimate deciders may use the "heavenly twins" of intuition and creativity and how they can train and enhance them. Finally, the author portrays intu-creativity as the measurable key to the secret of success in all human domains, and outlines the future application of this absolutely ground breaking work.
