Well, we seem to have solved the riddle of errors with comparatively little trouble! They are not accidents; they are serious mental acts; they have their meaning; they arise through the concurrence—perhaps better, the mutual interference—of two different intentions. But now I can well understand that you want to overwhelm me with a flood of questions and doubts, which must be answered and resolved before we can enjoy this first result of our efforts. I certainly do not want to press any hasty conclusions upon you. Let us coolly consider everything in turn. What would you like to say? Whether I think that this explanation accounts for all cases of slips of the tongue or only for a certain number? Whether this conception can be extended to the many other types of errors, to misreading, slips of the pen, forgetting, wrongly performed actions, mislaying things and so on? What part the factors of fatigue, excitement, absent-mindedness and distraction of attention play in regard to the mental nature of errors? Besides this, it is clearly seen that of the two competing meanings in the slip one is always manifest, but not always the other. How is one to arrive at the latter? And if one believes that one has guessed it, how is one to find proof that this is not merely a probability but the only true meaning? Is there anything else you wish to ask? If not, then I myself will continue. I will remind you that we are not really greatly concerned with errors in themselves, but that we wished to learn from a study of them something of value from the point of view of psycho-analysis. Therefore I will put this question: What sort of purposes or tendencies are these which thus interfere with other intentions, and what is the relation between the interfering tendency and the other? Thus, as soon as we have found the answer to the riddle, our efforts begin again. Very well then; is this the explanation of all cases of slips of the tongue? I am very much inclined to think so, and for this reason, because whenever one examines an instance of it this type of solution may be found. Still, one cannot prove that a slip of the tongue cannot come to pass without the agency of this mechanism. It may be so: for our purposes it is a matter of indifference, theoretically; for the conclusions which we wish to draw by way of an introduction to psycho-analysis remain valid, even if only a small proportion of the total incidence of slips of the tongue comes under our explanation, and this is certainly not so. The next question, whether this explanation extends to other forms of errors, may be answered by way of anticipation in the affirmative. You can convince yourselves of it when we turn to consider examples of slips of the pen, of wrongly performed acts, and so on. I propose, however, for technical reasons that we should postpone doing this until we have investigated the slip of the tongue itself more thoroughly.
