When Carl Jung became popular, he had a serious problem in his hands, because at the same time, Sigmund Freud was also popular and influential, and as you can well imagine, there was quite a bit of a war going on between these two very prominent forefathers of modern psychology and psychotherapy.
Psychotherapy is still a valid discipline today. It helps millions of people overcome issues. There are lots of people who used to be disabled by fear or paralyzed by pride, narcissism and anger who are now living effective normal lives. This was all made possible by psychotherapy in its current form.
However, if you were to take Sigmund Freud and put him in a time capsule and fast-forward to today, his mind would probably be blown because the psychotherapy being practiced now is so different from the therapy that he used on his patients, you might think Sigmund Freud has no part in psychotherapy. This also is due in no small measure to the fact that a lot of his theories have been debunked and discredited throughout the years.
Which sheds a spotlight on Carl Jung. He did not suffer the same deep level and extensive destruction of historical reputation that happened to Sigmund Freud. At some level or other, there are still people who believe in Jungian archetypes. Now, I’m not quite sure about how relevant this 1800s’ methodology is to psychotherapy, but I can guarantee that it’s relevant when it comes to cultural criticism.
