denies us the information; and, of course, that is also the case when the subject is not present to give us the information. We are, then, as in the case of the legal procedure, dependent on circumstances which make a decision at one time seem more, and at another time, less probable to us. At law, one has to declare a defendant guilty on circumstantial evidence for practical reasons. We see no such necessity; but neither are we forced to forego the use of these circumstances. It would be a mistake to believe that a science consists of nothing but conclusively proved theorems, and any such demand would be unjust. Only a person with a mania for authority, a person who must replace his religious catechism with some other, even though it be scientific, would make such a demand. Science has but few apodeictic precepts in its catechism; it consists chiefly of assertions which it has developed to certain degrees of probability. It is actually a symptom of scientific thinking if one is content with these approximations of certainty and is able to carry on constructive work despite the lack of the final confirmation.
But where do we get the facts for our interpretations, the circumstances for our proof, when the further remarks of the subject under analysis do not themselves elucidate the meaning of the error? From many sources. First of all, from the analogy with phenomena extraneous to the psychology of errors; as, for example, when we assert that the distortion of a name as a slip of the tongue has the same insulting significance as an intentional name distortion. We get them also from the psychic situation in which the error occurred, from our knowledge of the character of the person who committed the error, from the impressions which that person received before making the error, and to which he may possibly have reacted with this error. As a rule, what happens is that we find the meaning of the error according to general principles. It is then only a conjecture, a suggestion as to what the meaning may be, and we then obtain our proof from examination of the psychic situation. Sometimes, too, it happens that we have to wait for subsequent developments, which have announced themselves, as it were, through the error, in order to find our conjecture verified.
I cannot easily give you proof of this if I have to limit myself to the field of tongue slips, although even here there are a few good examples. The young man who wished to “inscort” the lady is certainly shy; the lady whose husband may eat and drink whatever she wants I know to be one of those energetic women who know how to rule in the home. Or take the following case: At a general meeting of the Concordia Club, a young member delivers a vehement speech in opposition, in the course of which he addresses the officers of the society as: “Fellow committee lenders.” We will conjecture that some conflicting idea militated in him against his opposition, an idea which was in some way based on a connection with money lending. As a matter of fact, we learn from our informant that the speaker was in constant money difficulties, and had attempted to raise a loan. As a conflicting idea, therefore, we may safely interpolate the idea, “Be more moderate in your opposition, these are the same people who are to grant you the loan.”
But I can give you a wide selection of such circumstantial proof if I delve into the wide field of other kinds of error.
If anyone forgets an otherwise familiar proper name, or has difficulty in retaining it in his memory despite all efforts, then the conclusion lies close at hand, that he has something against the bearer of this name and does not like to think of him. Consider in this connection the following revelation of the psychic situation in which this error occurs:
“A Mr. Y. fell in love, without reciprocation, with a lady who soon after married a Mr. X. In spite of the fact that Mr. Y. has known Mr. X. a long time, and even has business relations with him, he forgets his name over and over again, so that he found it necessary on several occasions to ask other people the man’s name when he wanted to write to Mr. X.”12
Mr. Y. obviously does not want to have his fortunate rival in mind under any condition. “Let him never be thought of.”
Another example: A lady makes inquiries at her doctor’s concerning a mutual acquaintance, but speaks of her by her maiden name. She has forgotten her married name. She admits that she was much displeased by the marriage, and could not stand this friend’s husband.13
Later we shall have much to say in other relations about the matter of forgetting names. At present we are predominantly interested in the psychic situation in which the lapse of memory occurs.
The forgetting of projects can quite commonly be traced to an antagonistic current which does not wish to carry out the project. We psychoanalysts are not alone in holding this view, but this is the general conception to which all persons subscribe the daily affairs, and which they first deny in theory. The patron who makes apologies to his protegé, saying that he has forgotten his requests, has not squared himself with his protegé. The protegé immediately thinks: “There’s nothing to that; he did promise but he really doesn’t want to do it.” Hence, daily life also proscribes forgetting, in certain connections, and the difference between the popular and the psychoanalytic conception of these errors appears to be removed. Imagine a housekeeper who receives her guest with the words: “What, you come today? Why, I had totally forgotten that I had invited you for today”; or the young man who might tell his sweetheart that he had forgotten to keep the rendezvous which they planned. He is sure not to admit it, it were better for him to invent the most improbable excuses on the spur of the moment, hindrances which prevented him from coming at that time, and which made it impossible for him to communicate the situation to her. We all know that in military matters the excuse of having forgotten something is useless, that it protects one from no punishment; and we must consider this attitude justified. Here we suddenly find everyone agreed that a certain error is significant, and everyone agrees what its meaning is. Why are they not consistent enough to extend this insight to the other errors, and fully to acknowledge them? Of course, there is also an answer to this.
If the meaning of this forgetting of projects leaves room for so little doubt among laymen, you will be less surprised to find that poets make use of these errors in the same sense. Those of you who have seen or read Shaw’s Caesar and Cleopatra will recall that Caesar, when departing in the last scene, is pursued by the idea that there was something more he intended to do, but that he had forgotten it. Finally he discovers what it is: to take leave of Cleopatra. This small device of the author is meant to ascribe to the great Caesar a superiority which he did not possess, and to which he did not at all aspire. You can learn from historical sources that Caesar had Cleopatra follow him to Rome, and that she was staying there with her little Caesarion when Caesar was murdered, whereupon she fled the city.
The cases of forgetting projects are as a rule so clear that they are of little use for our purpose, i.e., discovering in the psychic situation circumstantial evidence of the meaning of the error. Let us, therefore, turn to a particularly ambiguous and untransparent error, that of losing and mislaying objects. That we ourselves should have a purpose in losing an object, an accident frequently so painful, will certainly seem incredible to you. But there are many instances similar to the following: A young man loses the pencil which he had liked very much. The day before he had received a letter from his brother-in-law, which concluded with the words, “For the present I have neither the inclination nor the time to be a party to your frivolity and your idleness.”14 It so happened that the pencil had been a present from this brother-in-law. Without this coincidence we could not, of course, assert that the loss involved any intention to get rid of the gift. Similar cases are numerous. Persons lose objects when they have fallen out with the donors, and no longer wish to be reminded of them. Or again, objects may be lost if one no longer likes the things themselves, and wants to supply oneself with a pretext for substituting other and better things in their stead. Letting a thing fall and break naturally shows the same intention toward that object. Can one consider it accidental when a school child just before his birthday loses, ruins or breaks his belongings, for example his school bag or his watch?
He who has frequently experienced the annoyance of not being able to find something which he has himself put away, will also be unwilling to believe there was any intent behind the loss. And yet the examples are not at all
