I must go back a little, in order to make the matter intelligible. It may be safely said that during psycho-analytic treatment the formation of new symptoms is invariably stopped. But the productive powers of the neurosis are by no means extinguished; they are occupied in the creation of a special class of mental structures, for the most part unconscious, to which the name of ‘transferences’ may be given.
What are transferences? They are new editions or facsimiles of the impulses and phantasies which are aroused and made conscious during the progress of the analysis; but they have this peculiarity, which is characteristic for their species, that they replace some earlier person by the person of the physician. To put it another way: a whole series of psychological experiences are revived, not as belonging to the past, but as applying to the person of the physician at the present moment. Some of these transferences have a content which differs from that of their model in no respect whatever except for the substitution. These then – to keep to the same metaphor – are merely new impressions or reprints. Others are more ingeniously constructed; their content has been subjected to a moderating influence – to sublimation, as I call it – and they may even become conscious, by cleverly taking advantage of some real peculiarity in the physician’s person or circumstances and attaching themselves to that. These, then, will no longer be new impressions, but revised editions.
If the theory of analytic technique is gone into, it become, evident that transference is an inevitable necessity. Practical experience, at all events, shows conclusively that there is no means of avoiding it, and that this latest creation of the disease must be combated like all the earlier ones. This happens, however, to be by far the hardest part of the whole task. It is easy to learn how to interpret dreams, to extract from the patient’s associations his unconscious thoughts and memories, and to practise similar explanatory arts: for these the patient himself will always provide the text. Transference is the one thing the presence of which has to be detected almost without assistance and with only the slightest clues to go upon, while at the same time the risk of making arbitrary inferences has to be avoided. Nevertheless, transference cannot be evaded, since use is made of it in setting up all the obstacles that make the material inaccessible to treatment, and since it is only after the transference has been resolved that a patient arrives at a sense of conviction of the validity of the connections which have been constructed during the analysis.
