SECOND LECTURE. THE PSYCHOLOGY OF ERRORS

WE begin with an investigation, not with hypotheses. To this end we choose certain phenomena which are very frequent, very familiar and very little heeded, and which have nothing to do with the pathological, inasmuch as they can be observed in every normal person. I refer to the errors which an individual commits - as for example, errors of speech in which he wishes to say something and uses the wrong word; or those which happen to him in writing, and which he may or may not notice; or the case of misreading, in which one reads in the print or writing something different from what is actually there. A similar phenomenon occurs in those cases of mishearing what is said to one, where there is no question of an organic disturbance of the auditory function.
Another series of such occurrences is based on forgetfulness - but on a forgetfulness which is not permanent, but temporary, as for instance when one cannot think of a name which one knows and always recognizes; or when one forgets to carry out a project at the proper time but which one remembers again later, and therefore has only forgotten for a certain interval. In a third class this characteristic of transience is lacking, as for example in mislaying things so that they cannot be found again, or in the analogous case of losing things. Here we are dealing with a kind of forgetfulness to which one reacts differently from the other cases, a forgetfulness at which one is surprised and annoyed, instead of considering it comprehensible.
