A unitary theory of psychoanalysis in the place of the present pluralistic
theoretical culture is presented. Although alternative theoretical systems
to the basic theory discovered and expanded by Freud have been present sinc
e the beginnings of psychoanalysis, their modern forms took root in the lat
e 1960s and received quasi-official sanction and status with the posing of
the question "One Psychoanalysis or Many?" in the Presidential Address of t
he International Psychoanalytic Association in 1988 (R. Wallerstein, 1988),
to which the answer automatically given was "many." Proposed to this quest
ion is the answer of "one," a unified, composite theory of psychoanalysis t
hat is to be distinguished from nonpsychoanalytic theories of human behavio
r. The reasoning and contents behind such an approach are described.
