Freud and Jung's Correspondence: The Story of a Friendship and Professional Relationship

In their correspondence between 1906 and 1913, Freud and Jung first had friendly, then gradually more tense exchanges, which eventually led to the breakdown of their relationship.

In 1906, Jung wrote to Freud for the first time after being strongly influenced by Freud's 1900 book, The Interpretation of Dreams. Freud's reply was kind and enthusiastic, and he gladly welcomed Jung's interest and support. In the early part of their correspondence, they both treated each other with great respect, Freud saw Jung as a talented follower, while Jung respected Freud as a master, and became an enthusiastic supporter of psychoanalysis. During their correspondence, they discussed professional questions such as the analysis of dreams, psychotherapy techniques, and the causes of mental illness.

Freud considered Jung's role in spreading psychoanalysis outstanding, especially because Jung was not Jewish, which Freud believed could help the field gain wider acceptance. Jung gladly accepted Freud's trust and became a devoted follower of psychoanalysis.

 As the correspondence went on, more and more tension appeared between them. Jung gradually began to develop his own theoretical direction, which differed from Freud's strictly sex-drive-based views. Jung's interest in religion, spirituality, and the collective unconscious was foreign to Freud.

According to Jung, human behavior is influenced not only by sexual drives, but also by ancient, collective experiences and archetypes carried by the collective unconscious, while Freud continued to see sexuality and repression as the most important foundations of psychology.

In their correspondence, these theoretical differences were given more and more emphasis, Freud became increasingly worried that Jung was moving away from the psychoanalytic principles he had developed, and tried to steer him back to his own ideas. Jung, however, followed an increasingly independent path. In the final phase of their correspondence, the tone became openly tense. Freud found it hard to accept Jung's independence and new theories, while Jung felt that Freud was clinging too rigidly to his own views. In 1913, they finally ended their relationship.

In the last letters, they both admitted that because of their disagreements they could no longer work together, and their friendship ended.

Freud and Jung's correspondence was not only an exchange of ideas between two great minds, but also reflected the paths of the development of psychoanalysis and psychology.

Their separation led to the formation of two different psychological schools: Freud's classical psychoanalysis continued to emphasize the role of drives, especially sexuality, while Jung's analytical psychology focused on the spiritual and archetypal dimensions of the unconscious.

Their correspondence is still a fundamental source for research into the history of psychology, and it offers insight into how the ideas developed that still define the different branches of psychotherapy today.
