The human body is the one analogy that points toward a convincing model for the organization of a planetary society. There is no other model that mirrors its complexity or prosperity upon which we can rely. Human society is not a mass of individually differentiated cells but of associations of tissues and organs, systems and will, intelligence and common purpose. The modes of operation that characterize man’s biological nature illustrate fundamental principles of social and civilizational existence. Chiefly, unity in diversity is championed by the existence of each and every human frame. Paradoxically, it is the wholeness and complexity of the human body–and the perfect integration of its component elements–that permits the full realization of the distinctive potentialities inherent in each cell.
