We have defined above the one result of condensation—the manifold application of the same material, play upon words, and similarity of sound—as a localized economy, and have also referred the pleasure produced by harmless wit to that economy. At a later place we have found that the original purpose of wit consisted in producing this kind of pleasure from words, a process which was permitted to the individual during the stage of playing, but which became banked in during the course of intellectual development or by rational criticism. Now we have decided upon the assumption that such condensations as serve the technique of wit originate automatically and without any particular purpose during the process of thinking in the unconscious. Have we not here two different conceptions of the same fact which seem to be incompatible with each other? I do not think so. To be sure, there are two different conceptions, and they demand to be brought in unison, but they do not contradict each other. They are merely somewhat strange to each other, and as soon as we have established a relationship between them we shall probably gain in knowledge. That such condensations are sources of pleasure is in perfect accord with the supposition that they easily find in the unconscious the conditions necessary for their origin; on the other hand, we see the motivation for the sinking into the unconscious in the circumstance that the pleasure-bringing condensation necessary to wit easily results there. Two other factors also, which upon first examination seem entirely foreign to each other and which are brought together quite accidentally, will be recognized on deeper investigation as intimately connected, and perhaps may be found to be substantially the same. I am referring to the two assertions that on the one hand wit could form such pleasure-bringing condensations during its development in the stage of playing, that is, during the infancy of reason; and, on the other hand, that it accomplishes the same function on higher levels by submerging the thought into the unconscious. For the infantile is the source of the unconscious. The unconscious mental processes are no others than those which are solely produced during infancy. The thought which sinks into the unconscious for the purpose of wit-formation only revisits there the old homestead of the former playing with words. The thought is put back for a moment into the infantile state in order to regain in this way childish pleasure-sources. If, indeed, one were not already acquainted with it from the investigation of the psychology of the neuroses, wit would surely impress one with the idea that the peculiar unconscious elaboration is nothing else but the infantile type of the mental process. Only it is by no means an easy matter to grasp, in the unconscious of the adult, this peculiar infantile manner of thinking, because it is usually corrected, so to say, _statu nascendi_. However,
