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 to-day? Why, I had totally forgotten that I had invited you for to-day"; 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.
