Schultz, a psychological historian, said: "Jung's thought can stimulate people's thoughts and is novel. He put forward a concept of optimism about people, which many people think is a welcome change because he broke away from Freud. "
As far as the comparison between Jung and Freud is concerned, Murphy, another psychohistory family, thinks that Freud and Jung are both prophets, shouldering completely different missions. Freud saw that great power swept away everything, and the world was inevitably destroyed, so he could only make some perfunctory protests. However, in Jung's view, "there is an ever-expanding field that allows direct contact with sacred things, and there is an encouragement that makes patients and doctors willing to accept and move forward freely and unimpeded in the direction of mysterious pursuit." People may imagine that the former is a firm figure, "bravely fighting against a force different from the universe, which is grand but desolate." For this universe, human beings can only put forward partial and limited defense; On the other hand, the latter is a guide to a challenging world. In his view, for this world, human beings are really integrated with it.
According to psychologist Stoll, people greatly underestimated the value of Jung's theory, mainly because Jung could not express his thoughts in more concise and understandable language. Freud has a great advantage in writing. His article is really thorough and persuasive, so it is easy for him to stop criticizing and convince readers. Jung emphasized the spiritual aspect of human nature that is opposite to physiology, which formed an important and necessary contrast with Freud's excessive infatuation with the body. It is easy for people to lose patience with jung, and find his mysterious prejudice, his secular view and the ghosts and gods in his autobiography particularly unacceptable. However, his thoughts on introverted and extroverted personalities, his hypothesis that psychology has a self-regulating mechanism, his description of the process of individualization and his belief that schizophrenia can be cured by symbolic means are of far-reaching significance.
