In the first mentioned and more frequent cases of misreading, two factors are neglected to which we gave an important role in the mechanism of errors: the conflict of two tendencies and the suppression of one which then indemnifies itself by producing the error. Not that anything like the opposite occurs in misreading, but the importunity of the idea content which leads to misreading is nevertheless much more conspicuous than the suppression to which the latter may previously have been subjected. Just these two factors are most tangibly apparent in the various situations of errors of forgetfulness. Forgetting plans is actually uniform in meaning; its interpretation is, as we have heard, not denied even by the layman. The tendency interfering with the plan is always an antithetical intention, an unwillingness concerning which we need only discover why it does not come to expression in a different and less disguised manner. But the existence of this unwillingness is not to be doubted. Sometimes it is possible even to guess something of the motives which make it necessary for this unwillingness to disguise itself, and it always achieves its purpose by the error resulting from the concealment, while its rejection would be certain were it to present itself as open contradiction. If an important change in the psychic situation occurs between the formulation of the plan and its execution, in consequence of which the execution of the plan does not come into question, then the fact that the plan was forgotten is no longer in the class of errors. One is no longer surprised at it, and one understands that it would have been superfluous to have remembered the plan; it was then permanently or temporarily effaced. Forgetting a plan can be called an error only when we have no reason to believe there was such an interruption.
