I still have another theme to treat which plays an undesirably great part in the work of such a cathartic analysis. I have already admitted the possibility that the pressure procedure may fail and despite all assurance and urging it may evoke no reminiscences. I also stated that two possibilities are to be considered, there is really nothing to evoke in the place where we investigate—that can be recognized by the perfectly calm expression of the patient—or, we have struck against a resistance to be overcome only at some future time. We are confronted with a new layer into which we cannot as yet penetrate, and this can again be read from the drawn and psychic exertion of the patient’s expression. A third cause may be possible which also indicates an obstacle, not as to the purport, but externally. This cause occurs when the relation of the patient to the physician is disturbed, and signifies the worst obstacle that can be encountered. One may consider that in every more serious analysis. I have already alluded to the important rôle falling to the personality of the physician in the creation of motives which are to overcome the psychic force of the resistance. In not a few cases, especially in women and where we deal with the explanation of erotic streams of thought, the cooperation of the patient becomes a personal sacrifice which must be recompensed by some kind of a substitute of love. The great effort and the patient friendliness for the physician suffice as such substitutes. If this relation of the patient to the physician is disturbed the readiness of the patient fails; if the physician desires information concerning the next pathogenic idea, the patient is confronted by the consciousness of the unpleasantness which has accumulated in her against the physician. As far as I have discovered this obstacle occurs in three principal cases: 1. In personal estrangement, if the patient believes herself slighted, disparaged and insulted, or if she hears unfavorable accounts concerning the physician and his methods of treatment. This is the least serious case. The obstacle can readily be overcome by discussion and explanation, although the sensitiveness and the suspicion of hysterics can occasionally manifest itself in unsuspected dimensions.
