by Erich Fromm
During the last 35 years, I have written many works, in which — under different aspects — I tried to explain that there are not only points where Marxism and psychoanalysis overlap but that there is also an intrinsic interdependency between the two. This means, I do not only believe that a synthesis is possible but also an existential necessity.
Freud and Marx have in common that both — the first contrary to pre-Marxist sociology, the second contrary to earlier psychology — are concerned not as much with superficial phenomena as rather with driving forces, which act in certain directions and with varying intensity, and evoke phenomena that are changing and temporary.
Psychoanalysis is the only scientific form of psychology, as Marxism is the only scientific form of sociology. Only these two systems allow us to understand the hidden driving forces behind the phenomena and to predict what happens to an individual in a certain society when, under certain conditions, the acting forces evoke phenomena that seem to be exactly the opposite of what they actually are. In the field of individual psychology as well as in sociology, non-dynamic thinking is surprised when deeply effecting, existential transformations occur, while dynamic thinking, which recognizes forces that remain invisible from the surface, is able to predict probable transformations.
