Resistances of this sort must not be narrow-mindedly condemned. They contain so much of the most important material of the patient's past and reproduce it in such a convincing manner, that they become of the greatest aid to the analysis, if a skillful technique is able to turn them in the right direction. It is only remarkable that this material is at first always in the service of the resistance, for which it serves as a barrier against the treatment. One can also say that here are traits of character, adjustments of the ego which were mobilized in order to defeat the attempted change. We are thus able to learn how these traits arose under the conditions of the neurosis, as a reaction to its demands, and to see features more clearly in this character which could otherwise not have shown up so clearly or at least not to this extent, and which one may therefore designate as latent. You must also not get the impression that we see an unforeseen endangering of the analytic influence in the appearance of these resistances. On the contrary, we know that these resistances must come to light; we are dissatisfied only when we do not provoke them in their full strength and so make them plain to the patient Indeed, we at last understand that overcoming these resistances is the essential achievement of analysis and is that portion of the work which alone assures us that we have accomplished something with the patient. You must also take into account the fact that any accidental occurrences which arise during the treatment will be made use of by the patient as a disturbance--every diverting incident, every statement about analysis from an inimical authority in his circle, any chance illness or any organic affection which complicates the neurosis; indeed, he even uses every improvement of his condition as a motive for abating his efforts. You will then have gained an approximate, though still an incomplete picture of the forms and devices of the resistance which must be met and overcome in the course of every analysis. I have given this point such detailed consideration because I am about to inform you that our dynamic conception of the neurosis is based on this experience with the resistance of neurotic patients against the banishment of their symptoms. Breuer and I both originally practiced psycho-therapy by means of hypnosis. Breuer's first patient was treated throughout under a condition of hypnotic suggestibility, and I at first followed his example. I admit that my work at that time progressed easily and agreeably and also took much less time. But the results were capricious and not permanent; therefore I finally gave up hypnotism. Then only did I realize that no insight into the forces which produce these diseases was possible as long as one used hypnotism. The condition of hypnosis could prevent the physician from realizing the existence of a resistance. Hypnosis drives back the resistance and frees a certain
