Modern Psychology: C. G. Jung’s Lectures at the ETH Zürich, 1933-1941
But this outward movement is not just ridiculous, for it is part of the psychological growth of man.
It is a right attitude for children and young people who have to forget the psychic background in order to go wholeheartedly into the world where they must make their way.
Youth has to build many walls in order to shut off the background from the ego, so that it may believe in the outer world; for to remain under the fascination of the inner images causes hesitation and lack of accomplishment, and to live, to be wholly devoted to something, is also an art which must not be despised.
Getting into life is absolutely essential to young people.
One could argue that they should not hear the things of which I have been speaking, yet those among them who are philosophically, religiously or artistically minded, must know that something exists besides the outer world; for if they misplace the values which belong to the inner world and try to see them outside, their world picture will become distorted.
Many difficulties arise from the fact that relationships and other outside values are treated with an importance which they do not deserve. ~Carl Jung, Modern Psychology, Vol. 1, Page 45.
