Psychoanalyst and historian Henry Zvi Lothane has also criticized some of the central ideas of relational psychoanalysis, from both historical and psychoanalytic perspectives. Historically, Lothane believes relational theorists overstate the non-relational aspects of Freud as ignore its relational aspects. Lothane maintains that, though Freud's theory of disorder is "monadic," i.e. focused more or less exclusively on the individual, Freud's psychoanalytic method and theory of clinical practice is consistently dyadic or relational. From a theoretical perspective, Lothane has criticized the term "relational" in favor of Harry Stack Sullivan's term "interpersonal". Lothane developed his concepts of "reciprocal free association" as well as "dramatology" as ways of understanding the interpersonal or relational dimension of psychoanalysis.
