Psychoanalysis As a Scientific Theory
HEINZ HARTMANN, M.D.
Former President
International Society for Psychoanalysis
WHEN some forty-five years ago Freud (12) wrote for the first time about the philosophical interest in analysis, his main point was that philosophy could not avoid taking fully into account what he then called âthe hypothesis of unconscious mental activities.â He also mentioned that philosophers may be interested in the interpretation of philosophical thought in terms of psychoanalysisâadding, though, here as elsewhere, that the fact that a theory or doctrine is determined by psychological processes of many kinds does not necessarily invalidate its scientific truth. Since then, the knowledge of human behavior and motivation we owe to analysis has greatly increased, has become much more comprehensive but also more specific; and this development has certainly influenced not only social science, anthropology, and medicine, but also philosophy in a broad sense. This does not, though, necessarily mean that analysis can âanswerâ what one usually calls philosophical problems; it usually means that it leads to looking at them from a new angle. Some of its potentialities in this respect have been made use of only rather scantily so far. I am thinking, for example, of its possible contribution toward a better understanding of ethical problems. The interest psychoanalysis may have for philosophers has clearly two aspects: it resides partly in the new psychological findings and theories of analysis, but also in certain questions of methodology raised by Freudâs and other psychoanalystsâ approach to the study of man.
In speaking of psychoanalysis one often refers to a therapeutic technique. One may also refer to a method of psychological investigation whose main aspects are free association and interpretation; or, finally, to a body of facts and theories (Freud, 13). In this last sense, we would certainly consider as psychoanalytical any knowledge gained directly by Freudâs method of investigation; but many of us would today consider analysis to include related procedures such as the application of psychoanalytic insights to data of direct child observation, a field which has grown in importance in the last two decades. Of the three aspects just mentioned, it is the method of exploration that has undergone the least change; it is commonly used in a situation defined by a certain set of rules and referred to as the psychoanalytic situation or the psychoanalytic interview. The therapeutic technique has been repeatedly modified, and psychoanalytic theory has gone through a series of more or less radical modifications, by Freud and by others. I want to emphasize that the interrelations among these three aspects are, in analysis, a central topicâthough in the context of this presentation I can refer to them only occasionally.
The theories of psychoanalysis follow principles of systematization, as do theories in other fields. Freud, however, did not speak of analysis as a âsystem,â but rather accentuated its unfinished character, its flexibility, and the tentative nature of a considerable part of it. Actually, adjustments and reformulations of various aspects of theory have repeatedly become necessary. There are chapters such as the psychology of the dream, of libidinal development, of anxiety, and of symptom formation, that have been more systematically worked out than others. Psychoanalysis is obviously far from being a closed system of doctrines, though it has sometimes been represented as such. Also, though some fundamental tenets of psychoanalysis are accepted by all (Freudian) analysts, agreement on all of them is obviously lacking.
There is in analysis a hierarchy of hypotheses as to their closeness to observation, their generality, and the degree to which they have been confirmed. It appears that a neater classification as to these points and a higher degree of systematization (considering the different levels of theorizing) than exist today would not only facilitate my task in discussing psychoanalysis as a scientific theory but also clarify the standing of analysis as a scientific discipline. Promising efforts in this direction have been made and are being made by analysts and also by nonanalysts, but as yet no complete and systematical outline drawn from this angle is available; a recent work by David Rapaport (30), soon to be published, may come close to performing this task. This is probably the reason, or one of the reasons, that in more or less general presentations of psychoanalysis references to its history abound, and the reader will forgive me if they do in this paper too, at least in its first part. I shall mostly refer to the work of Freud, because most of the more general theories of analysis have their origin in it, and because he is in many ways more representative of psychoanalytic thinking than anybody else.
Often historical explanations are substituted for system; an attempt is made to clarify the function of propositions in their relation to others by tracing their place in the development of analysis. Also, without such historical reference it happens over and over again that analytical hypotheses are dealt with on one level, so to say, which belong to different phases of theory formation, and some of which have actually been discarded and replaced by others. Again, because of the comparatively low level of systematization, I think it is true that even today a thorough knowledge of at least some chapters of analytic theory cannot be acquired without knowledge of its history (Hartmann, 16).
From the beginning, explanations of human behavior in terms of propositions about unconscious mental processes have been an essential part and one characteristic feature of psychoanalysis. I may, then, start by introducing Freudâs concepts of unconscious processes. He makes a distinction between two forms of unconscious mental activity. The one, called preconscious, functions more or less as conscious activities do. It is not conscious, in a descriptive sense, but can become conscious without having to overcome powerful counterforces. Where such overcoming of resistances is necessary, as is the case with repressed material, we speak of unconscious processes in the stricter, the dynamic, sense of the word. The dynamic impact of these latter unconscious processes on human behaviorâand not only in the case of mental diseaseâis one main tenet of Freudâs theory of unconscious mental activities.
There is rather wide agreement that conscious data are insufficient for the explanation of a considerable part of behavior, and particularly of those aspects that were first studied in analysis. However, its critics have repeatedly claimed that the introduction of unconscious processes is superfluous. The explanation needed could be stated, or should be sought for, in terms of the more reliable data of brain physiology. The question here is not just whether, and why, explanations based on such data would be per se more reliable, nor why psychological hypotheses about mental processes ought not to be introduced in explaining human behavior. We have also to consider the fact that, given the actual state of brain physiology, many and even comparatively simple aspects of behavior of the kind we are dealing with in analysis cannot be explained. To rely on brain physiology alone would mean to renounce explanation of the greatest part of the field that psychoanalysis has set out to explain. Or, if one should insist on attempting an explanation on physiological grounds, the resultant hypotheses would of necessity be considerably more tenuous and more speculative even than psychoanalytic hypotheses are suspected to be by its critics today.
Freud, well trained in the anatomy and physiology of the brain, actually started out by attempting to devise a physiological psychology that could provide him with concepts and hypotheses to account for his clinical insights. But beyond a certain point this approach proved of no use. He was thus led to replace it by a set of psychological hypotheses and constructs; and this step represents probably the most important turning point in the history of psychoanalysis. It was the beginning in analysis of psychological theory, the heuristic value of which he found to be greatly superiorâa point that, I think, has been corroborated by its subsequent development.
But it is true that even after this radical turn in his approach Freud held on to the expectation, shared by many analysts, that one day the development of brain physiology would make it possible to base psychoanalysis on its findings and theories. He did not think this would happen during his lifetime, in which he proved to be right. In the meantime certain, though limited, parallels between analytic propositions and discoveries in the physiology of the brain have become apparent. Also, the usefulness of some psychoanalytic hypotheses for their field has been recognized by at least some representatives of brain research (Adrian, 1). As to the psychology of unconscious processes, I think it can be said that Freud in developing that part of analysis was much less interested in the ultimate ânatureâ or âessenceâ of such processesâwhatever this may meanâthan in finding a suitable conceptual framework for the phenomena he had discovered.
While Freud, after the first years of his scientific work, relinquished the attempt to account for his findings in terms of physiology, it is nevertheless characteristic of some of his psychoanalytic theorizing that he used physiological models. He was guided by the trend in German physiology which has been designated as the physicalist school (Bemfeld, 5), whose representatives were, among others, Helmholtz and Bruecke, the latter being one of Freudâs teachers. Certain aspects of the psychology of neurosis, for example, led him to introduce into psychoanalysis the concept of regression (to earlier stages of development), which had been used in the physiology of his day; this concept, though, acquired new meaning in the context in which he used it. Also, in making âfunctionâ the criterion for defining what he called the mental systems (ego, id, superego), Freud used physiology as a model. But this no longer implies any correlation to any specific physiological organization (Hartmann, Kris, Loewenstein, 21). The value of such borrowings or analogies has, of course, to be determined in every single instance by confronting their application with tested knowledge (data and hypotheses). Physiological models (also occasionally physical models, as is obvious, for instance, in Freudâs concept of a âmental apparatusâ) have been used also by other psychoanalysts (see Kubie in a recent lecture) in order to illustrate certain characteristics of mental phenomena or to suggest a new hypothesis. The use even of metaphors need not of necessity lead into muddled thinking once their place in theory has been clearly delineated. The danger that earlier implications of those model concepts might impair their fruitful use in the new context of psychoanalysis has on the whole been successfully avoided (Hartmann-Kris-Loewenstein).
The broadening of the scope of psychology that came about as the consequence of the inclusion of propositions about unconscious mental processes meant, first of all, that many aspects of a personâs life history that had never been explained beforeâand that, as a matter of fact, one had not even tried to explainâcould be accounted for in terms of the individualâs experience and dispositions. Causation in the field of personality is traceable only at its fringes without this broadening of theory. Freud was a strict determinist and often stated that to fill that gap in earlier psychological approaches, partly because of which the study of personality had been unsatisfactory, was one of his primary aims in developing analytic theory. More recently it has been said, by the mathematician von Mises (29), that the observations correspond rather to statistical than to causal relations. I may mention at this point that this interest in the causation of mental phenomena included, quite naturally, also the interest in what we call the genetic viewpoint, since Freudâs attention had been drawn to many facts of early childhood which had been unknown, and regularities in the relationships between early childhood situations and the behavior of the adult had become apparent. With Freud, the investigation of highly complex series of experience and behavior, extending over long periods of time, soon moved into the center of interest. Developmental research was to become equally important for psychoanalytic theory and practice. It is significant that the reconstructive approach in analysis led not only to the discovery of a great wealth of childhood material in every individual case, but also to the ascertainment of typical sequences of developmental phases. The genetic approach has become so pervasive, not only in psychopathology but also in psychoanalytic psychology in general, that in analysis phenomena are often grouped together, not according to their descriptive similarities but as belonging together if they have a common genetic root (oral character, anal character). It was only much later that this predominance of a genetic conceptualization was counterbalanced by a sharper distinction between genesis and function, to which I shall shortly return in speaking of the structural point of view.
Here I want to add that while I just spoke of the study of the individualâs âlife history,â it would be misleading (though it actually has been done) to classify this aspect of analysis as an historical discipline. This misinterpretation may be traceable to its comparison with archaeology, which Freud occasionally uses. It is true that most analytical knowledge has been gained in the psychoanalytic interview and that the concern with developmental problems refers primarily to the history of individuals. But this should not obfuscate the fact that the aim of these studies is (besides its therapeutic purpose) to develop lawlike propositions which then, of course, transcend individual observations.
At this point I should like briefly to summarize the role of psychoanalysis as a psychology of motivation, bearing in mind that nowadays psychoanalysis takes into consideration the interaction of the individual with his environment, as well as his so-called âinner-psychicâ processes. The study of these psychic processes constitutes what, in analysis, we call âmetapsychology,â a term that signifies not (as it might seem) that which is beyond psychology altogether, but simply those psychological investigations that are not limited to conscious phenomena, and that formulate the most general assumptions of analysis on the most abstract level of theory. Metapsychology is concerned with the substructures of personality, with the ego, the id, and the superego which are defined as units of functions. The id refers to the instinctual aspect, the ego to the reality principle and to the âcentralization of functional controlâ (to borrow a term from brain physiology). The superego has its biological roots in the long dependency on the parents and in the helplessness of the human child; it develops out of identifications with the parents; and it accounts for the fact that moral conflict and guilt feelings become a natural and fundamental aspect of human behavior. The theoretical and clinical advantage of the structural formulations, referring to the distinction of ego, id, superego, has several reasons. The most important is probably that the demarcation lines of the three systems, ego, id, superego are geared to the typical conflicts of man: conflicts with the instinctual drives, with moral conscience, and with the outside world. The paramount importance on neurotic and normal development of these conflicts, and of the ways to solve them, was one of the earliest discoveries of Freud and has remained central in psychoanalytic practice and theory ever since.
Critics of analysis often tend to underrate the wealth of individual data on which it is built. But on the other hand, it also happens that the theoretical nature of concepts like libido is not fully realized; for example, libido is often identified wit...
