John Bennett was a key expositor of Gurdjieff's ideas but a creative visionary in his own right. He developed the disciplines of systematics and structural communication as well as techniques of inner development that are integrated into our methodologies. He embraced the three main streams of influence - of science, psychology and traditions - that are discussed later in explaining the pattern of influences. Bennett researched a spiritual psychology, which we take as a point of departure. Anthony Blake worked with him over 15 years.
