Do not be offended, therefore, if, for the present, I treat you as I treat these neurotic patients. Frankly, I shall dissuade you from coming to hear me a second time. With this intention I shall show what imperfections are necessarily involved in the teaching of psychoanalysis and what difficulties stand in the way of gaining a personal judgment. I shall show you how the whole trend of your previous training and all your accustomed mental habits must unavoidably have made you opponents of psychoanalysis, and how much you must overcome in yourselves in order to master this instinctive opposition. Of course I cannot predict how much psychoanalytic understanding you will gain from my lectures, but I can promise this, that by listening to them you will not learn how to undertake a psychoanalytic treatment or how to carry one to completion. Furthermore, should I find anyone among you who does not feel satisfied with a cursory acquaintance with psychoanalysis, but who would like to enter into a more enduring relationship with it, I shall not only dissuade him, but I shall actually warn him against it. As things now stand, a person would, by such a choice of profession, ruin his every chance of success at a university, and if he goes out into the world as a practicing physician, he will find himself in a society which does not understand his aims, which regards him with suspicion and hostility, and which turns loose upon him all the malicious spirits which lurk within it. However, there are always enough individuals who are interested in anything which may be added to the sum total of knowledge, despite such inconveniences. Should there be any of this type among you, and should they ignore my dissuasion and return to the next of these lectures, they will be welcome. But all of you have the right to know what these difficulties of psychoanalysis are to which I have alluded.
