attention from this whole field. This is the reason why society will not tolerate the above-mentioned results of psychoanalytic research, and would prefer to brand it as aesthetically offensive and morally objectionable or dangerous. Since, however, one cannot attack an ostensibly objective result of scientific inquiry with such objections, the criticism must be translated to an intellectual level if it is to be voiced. But it is a predisposition of human nature to consider an unpleasant idea untrue, and then it is easy to find arguments against it. Society thus brands what is unpleasant as untrue, denying the conclusions of psychoanalysis with logical and pertinent arguments. These arguments originate from affective sources, however, and society holds to these prejudices against all attempts at refutation.
However, we may claim, ladies and gentlemen, that we have followed no bias of any sort in making any of these contested statements. We merely wished to state facts which we believe to have been discovered by toilsome labor. And we now claim the right unconditionally to reject the interference in scientific research of any such practical considerations, even before we have investigated whether the apprehension which these considerations are meant to instil are justified or not.
These, therefore, are but a few of the difficulties which stand in the way of your occupation with psychoanalysis. They are perhaps more than enough for a beginning. If you can overcome their deterrent impression, we shall continue.
SECOND LECTURE
THE PSYCHOLOGY OF ERRORS
We begin with an investigation, not with hypotheses. To this end we choose certain phenomena which are very frequent, very familiar and very little heeded, and which have nothing to do with the pathological, inasmuch as they can be observed in every normal person. I refer to the errors which an individual commits — as for example, errors of speech in which he wishes to say something and uses the wrong word; or those which happen to him in writing, and which he may or may not notice; or the case of misreading, in which one reads in the print or writing something different from what is actually there. A similar phenomenon occurs in those cases of mishearing what is said to one, where there is no question of an organic disturbance of the auditory function. Another series of such occurrences is based on forgetfulness — but on a forgetfulness which is not permanent, but temporary, as for instance when one cannot think of a name which one knows and always recognizes; or when one forgets to carry out a project at the proper time but which one remembers again later, and therefore has only forgotten for a certain interval. In a third class this characteristic of transience is lacking, as for example in mislaying things so that they cannot be found again, or in the analogous case of losing things. Here we are dealing with a kind of forgetfulness to which one reacts differently from the other cases, a forgetfulness at which one is surprised and annoyed, instead of considering it comprehensible. Allied with these phenomena is that of erroneous ideas — in which the element of transience is again prominent, inasmuch as for a while one believes something which, before and after that time, one knows to be untrue — and a number of similar phenomena of different designations.
These are all occurrences whose inner connection is expressed in the use of the same prefix of designation.1 They are almost all unimportant, generally temporary and without much significance in the life of the individual. It is only rarely that one of them, such as the phenomenon of losing things, attains to a certain practical importance. For that reason also they do not attract much attention, they arouse only weak affects.
It is, therefore, to these phenomena that I would now direct your attention. But you will object, with annoyance: “There are so many sublime riddles in the external world, just as there are in the narrower world of the psychic life, and so many wonders in the field of psychic disturbances which demand and deserve elucidation, that it really seems frivolous to waste labor and interest on such trifles. If you can explain to us how an individual with sound eyes and ears can, in broad daylight, see and hear things that do not exist, or why another individual suddenly believes himself persecuted by those whom up to that time he loved best, or defend, with the most ingenious arguments, delusions which must seem nonsense to any child, then we will be willing to consider psychoanalysis seriously. But if psychoanalysis can do nothing better than to occupy us with the question of why a speaker used the wrong word, or why a housekeeper mislaid her keys, or such trifles, then we know something better to do with our time and interest.”
My reply is: “Patience, ladies and gentlemen. I think your criticism is not on the right track. It is true that psychoanalysis cannot boast that it has never occupied itself with trifles. On the contrary, the objects of its observations are generally those simple occurrences which the other sciences have thrown aside as much too insignificant, the waste products of the phenomenal world. But are you not confounding, in your criticism, the sublimity of the problems with the conspicuousness of their manifestations? Are there not very important things which under certain circumstances, and at certain times, can betray themselves only by very faint signs? I could easily cite a great many instances of this kind. From what vague signs, for instance, do the young gentlemen of this audience conclude that they have won the favor of a lady? Do you await an explicit declaration, an ardent embrace, or does not a glance, scarcely perceptible to others, a fleeting gesture, the prolonging of a hand-shake by one second, suffice? And if you are a criminal lawyer, and engaged in the investigation of a murder, do you actually expect the murderer to leave his photograph and address on the scene of the crime, or would you, of necessity, content yourself with fainter and less certain traces of that individual? Therefore, let us not undervalue small signs; perhaps by means of them we will succeed in getting on the track of greater things. I agree with you that the larger problems of the world and of science have the first claim on our interest. But it is generally of little avail to form the definite resolution to devote oneself to the investigation of this or that problem. Often one does not know in which direction to take the next step. In scientific research it is more fruitful to attempt what happens to be before one at the moment and for whose investigation there is a discoverable method. If one does that thoroughly without prejudice or predisposition, one may, with good fortune, and by virtue of the connection which links each thing to every other (hence also the small to the great) discover even from such modest research a point of approach to the study of the big problems.”
Thus would I answer, in order to secure your attention for the consideration of these apparently insignificant errors made by normal people. At this point, we will question a stranger to psychoanalysis and ask him how he explains these occurrences.
His first answer is sure to be, “Oh, they are not worth an explanation; they are merely slight accidents.” What does he mean by this? Does he mean to assert that there are any occurrences so insignificant that they fall out of the causal sequence of things, or that they might just as well be something different from what they are? If any one thus denies the determination of natural phenomena at one such point, he has vitiated the entire scientific viewpoint. One can then point out to him how much more consistent is the religious point of view, when it explicitly asserts that “No sparrow falls from the roof without God’s special wish.” I imagine our friend will not be willing to follow his first answer to its logical conclusion; he will interrupt and say that if he were to study these things he would probably find an explanation for them. He will say that this is a case of slight functional disturbance, of an inaccurate psychic act whose causal factors can be outlined. A man who otherwise speaks correctly may make a slip of the tongue — when he is slightly ill or fatigued; when he is excited; when his attention is concentrated on something else. It is easy to prove these statements. Slips of the tongue do really occur with special frequency when one is tired, when one has a headache or when one is indisposed. Forgetting proper names is a very frequent occurrence under these circumstances. Many persons even recognize the imminence of an indisposition by the inability to recall proper names. Often also one mixes up words or objects during excitement, one
