Three idealized phases in life that prepare us for the next:
The Me. It focuses on creating order and on learning all the continuity conditions of life. It generally ranges from birth to about 30 years old.
The We. It focuses primarily on relations and symmetries, family and friends. It generally ranges from 30 to 60 years old.
The Thee. If focuses on harmony of the spheres, universals and constants, all things everywhere, and then throughout all time. It ideally ranges from 60 until we die. These are the wisdom years and our most dynamics years. We need to demand it of ourselves and of those who are entering this period of life.
This trifurcation of an individual life reflects a deep organizational structure throughout all times and all places right from the Planck base units to this very moment.
