ABSTRACT
M. Schur speaks inter alia of the id's relationship to the instinctual drives, of the concept wish which he describes as the functional unit of the id, of its development, of primary process, and of pleasure and unpleasure principles. There are many divergent views in the literature on "id", partly attributable to different views as to how the subject is to be approached. There is need in the further development of the tripartite structural theory to study the organization of the different functions which comprise the id, ego, and superego. Aaron Karush is described as defining id as "a collection of the earliest percepts of internal urges and their activities as well as those of the original objects which help reduce the tensions of a drive." The idea of id development has massive clinical evidence to support it; the question is how the progression through libidinal phases is most usefully conceptualised.
