The up surging archetypal material is the stuff of which mental illnesses are made.
The extraverted person cannot value anything from the inside, hence the superficiality of much academic psychology – psychological tests for example, or the physical explanations of mental experiences.
Our mental processes cannot escape the intermingling with these preexisting images, so it is easy to see why a new idea always has to fight for its life against these ancestral predispositions. ~Carl Jung, 1925 Seminar, Page 64
If ever there was a mental epidemic it is the actual mental condition in Germany. Hitler himself (from what I heard) is more than half crazy.
Holding lectures, giving instruction, pumping in knowledge, all these current university procedures are no use at all here. The only thing that really helps is self-knowledge and the change of mental and moral attitude it brings about.
