According to this web site, Jung and Freud are tops when it comes to academic fist-fights:
Probably one of the most famous rivalries in all of “Western” philosophy and science, Sigmund Freud started out as one of Carl Jung’s most beloved mentors before their close relationship soured. Now considered psychoanalysis’ two daddies, the intellectual juggernauts split mainly because of one massive disagreement — specifically, regarding the human unconscious. Jung didn’t believe his veritable Mr. Miyagi of all things psychological took it seriously enough. Their theories about suppressed and repressed thoughts and emotions lurking in the unconscious existed in harmony, but once Jung proposed the collective unconscious, everything began unraveling. His mentor proposed a structure involving some degree of collectivism, of course, though Jung considered it far bigger and more significant. Freud, on the other hand, saw the unconscious as a supplement to the overall psyche rather than its own unique, influential entity.
Which is good news for PUP as we will publish a new paperback titled Jung Contra Freud: The 1912 New York Lectures on the Theory of Psychoanalysis in December. These lectures, give in the autumn of 1912 are the pivotal moment that ignited this famous feud. This is where C. G. Jung set out his critique and reformulation of the theory of psychoanalysis. He challenged Freud’s understandings of sexuality, the origins of neuroses, dream interpretation, and the unconscious, and also became the first to argue that every analyst should themselves be analyzed.
While some parts of this material have previously appeared in Jung collections, the lectures in their entirety have never before been published as a separate volume. And as if that wasn’t enough, the book also features an introduction by Sonu Shamdasani, Philemon Professor of Jung History at University College London, and editor of Jung’s Red Book.
Now, back to feuding academics — what other feuds make the grade? coming in at number two are Nikolas Tesla and Thomas Edison, while C.S. Lewis and J.R.R. Tolkien nab the number three spot. Click over to read the complete list of these juicy academic spats.
