In the examples which I have given from my psychoanalyses it is found that the entire speech is either under the influence of thoughts which have become active simultaneously, or under absolutely unconscious thoughts which betray themselves either through the disturbance itself, or which evince an indirect influence by making it possible for the individual parts of the unconsciously intended speech to disturb one another. The retained or unconscious thoughts from which the disturbances in speech emanate are of most varied origin. A general survey does not reveal any definite direction. Comparative examinations of examples of mistakes in reading and writing lead to the same conclusions. Isolated cases, as in speech blunders, seem to owe their origin to an unmotivated work of condensation (_e.g._, the _Apel_). But we should be pleased to know whether special conditions must not be fulfilled in order that such condensation, which is considered regular in the dream-work and faulty in our waking thoughts, should take place. No information concerning this can be obtained from the examples themselves. But I merely refuse from this to draw the conclusion that there are no such conditions, as, for instance, the relaxation of conscious attention; for I have learned elsewhere that automatic actions are especially characterized by correctness and reliability. I would rather emphasize the fact that here, as so frequently in biology, it is the normal relations, or those approaching the normal, that are less favourable objects for investigation than the pathological. What remains obscure in the explanation of these most simple disturbances will, according to my expectation, be made clear through the explanation of more serious disturbances. Also mistakes in reading and writing do not lack examples in which more remote and more complicated motivation can be recognized. There is no doubt that the disturbances of the speech functions occur more easily and make less demand on the disturbing forces than other psychic acts.
