Space flights to other worlds are still a long way off, Jung answered.
‘Sooner or later man will have to return to earth, and to the land from which he comes; that is to say, man will have to return to himself.
Space flights are merely an escape, a fleeing away from oneself, because it is easier to go t:o Mars or to the moon than it is to penetrate one’s own being.
But what is dangerous about this frantic interest in spatial conquest is that it symbolizes a state of complete anxiety in man.
This anxiety would seem to be caused by a fear of the world’s population explosion. In a way, space flights seem to be an
instinctive reaction to this problem.’
