In the first-mentioned, more frequent cases of misreading two factors to which we ascribed great importance in the mechanism of errors are inconspicuous; these are, the conflict between two tendencies and the forcing back of one of them which compensates itself by producing the error. Not that anything contradictory of this occurs in misreading, but nevertheless the importunity of the train of thought tending to the mistake is far more conspicuous than the restraint which it may have previously undergone. Just these two factors are most clearly observable in the different situations in which errors occur through forgetfulness. The forgetting of resolutions has positively but one meaning; the interpretation of it, as we have heard, is not denied even by the layman. The tendency interfering with the resolution is always an opposing one, an unwillingness, concerning which it only remains to enquire why it does not come to expression in a different and less disguised form; for the existence of this opposing tendency is beyond doubt. Sometimes it is possible, too, to infer something of the motives which necessitate the concealment of this antipathy; one sees that it would certainly have been condemned if it declared its opposition openly, whereas by craft, in the error, it always achieves its end. When an important change in the mental situation occurs between the formation of the resolution and its execution, in consequence of which the execution would no longer be required, then if it were forgotten the occurrence could no longer come within the category of errors. There would be nothing to wonder at in the error, for one recognizes that it would have been superfluous to remember the resolution; it had been either permanently or temporarily cancelled. Forgetting to carry out a resolution can only be called an error when there is no reason to believe that any such cancellation has occurred.
