In 1923 he published Das Buch vom Es, an unusual work in which each chapter is in the form of a letter to a girlfriend addressed as "my dear“,
Association with Sigmund Freud and psychoanalysis[edit]
In his introduction to the 1949 English version[6] of Groddeck's Das Buch vom Es (1923),[7] Lawrence Durrell comments that Groddeck is often mistaken for an orthodox disciple of Sigmund Freud. He goes on to say "Groddeck was the only analyst whose views had some effect on Freud", and "while he accepts and employs much of the heavy equipment of the master, he is separated forever from Freud by an entirely different conception of the constitution and functioning of the human psyche."[8]
Freud mentions Groddeck in The Ego and the Id,[9] crediting him with giving a name to what Freud had already given a local habitation, to wit, the Id.
Now I think we shall gain a great deal by following the suggestion of a writer who, from personal motives, vainly asserts that he has nothing to do with the rigours of pure science. I am speaking of Georg Groddeck, who is never tired of insisting that what we call our ego behaves essentially passively in life, and that, as he expresses it, we are "lived" by unknown and uncontrollable forces. We have all had impressions of the same kind, even though they may not have overwhelmed us to the exclusion of all others, and we need feel no hesitation in finding a place for Groddeck's discovery in the structure of science. I propose to take it into account by calling the entity which starts out from the system Pcpt. and begins by being Pcs. the "ego", and by following Groddeck in calling the other part of the mind, into which this entity extends and which behaves as though it were Ucs., the "id". (Freud 1927/1961, 13).
Groddeck eventually had acrimonious disagreement with Freud about the definition and limitations of the It/Id/das Es.[a]Groddeck regarded the ego as an extension or a mask for the id, whereas Freud regarded them as separate constructs.
In contrast to Freud, Groddeck was primarily engaged with the treatment of chronically ill patients. Groddeck is considered by many as a founder of psychosomatic medicine – his reservations against strict science and orthodox medicine made him an outsider among psychoanalysts till today.[12]
Groddeck was a controversial but important figure within the psychoanalytic movement. He attended the congress of the German psychoanalytic association in 1930. He was invited to lecture to the British Psychoanalytic Society in 1928, and invited by Felix Boehm to lecture at the Berlin Institute in 1930. Eitingon disliked Groddeck until being treated by him in 1928, after which he regarded him warmly.
