Hans Loewald is a comprehensive and original theorist on a par with any major post-Freudian thinker, yet neither his ideas nor his person have become the basis for a Loewaldian school or approach, and he is not as well known as other innovators of comparable quality. In this paper the author attempts to characterize the scope and depth of Loewald's theory—his vision of the psyche and psychic life, or metapsychology, his characterization of the psychoanalytic process, and his vision of the clinical and human goals of psychoanalysis. She suggests that Loewald holds in all of these realms, and without apparent contradiction, a doubled—emphatically ego-psychological and emphatically object-relational—perspective, and an equal commitment to both the first topography and the structural theory. His views throughout are undergirded by a bi-directional developmental view that centers on differentiation and integration. The paper includes brief reflections on how to assess psychoanalytic theories, like Loewald's, developed before empirical research that seems to challenge them.
