Take for comparison the daily course of the sun – but a sun that is endowed with human feeling and man’s limited consciousness.
In the morning it rises from the nocturnal sea of unconsciousness and looks upon the wide, bright world which lies before it in an expanse that steadily widens the higher it climbs in the firmament.
In this extension of its field of action caused by its own rising, the sun will discover its significance; it will see the attainment of the greatest possible height, and the widest possible dissemination of its blessings, as its goal.
In this conviction the sun pursues its course to the unforeseen zenith-unforeseen, because its career is unique and individual, and the culminating point could not be calculated in advance.
At the stroke of noon the descent begins. And the descent means the reversal of all the ideals and values that were cherished in the morning. ~Carl Jung, “The Stages of Life” (1930). In CW 8: The Structure and Dynamics of the Psyche. P. 778.
