“The contribution of the Gestalt approach is the recognition that figure and ground are formally the same and may be exchanged without violence to the whole, and in fact must be changed for a complete experience of the whole. When we understand something, we stand under it, experience it from without as well as within.” So states Kurt von Meier and Clifford Barney at the beginning of this 1975 exploration into the relationships between the Gestalt therapy and psychology of Fritz Perls, mathematics, and knowledge of the divine as seen by Dante Alighieri.
