Page:Freud - Wit and its relation to the unconscious.djvu/46

 recall that Lipps has attempted to describe more fully the peculiarity of the brevity of wit (v. s., p. 11). Here our investigation started and demonstrated that the brevity of wit is often the result of a special process which has left a second trace—the substitutive formation—in the wording of the wit. By applying the process of reduction, which aims to cause a retrogression in the peculiar process of condensation, we find also that wit depends only upon the verbal expression which was produced by the process of condensation. Naturally our entire interest now centers upon this peculiar and hitherto almost neglected mechanism. Furthermore, we cannot yet comprehend how it can give origin to all that is valuable in wit; namely, the resultant pleasure.

Have processes similar to those here described as the technique of wit already been noted in another sphere of our psychic life? To be sure, in one apparently remote sphere. In 1900 I published a book which, as indicated by its title (The Interpretation of Dreams ), makes the attempt to explain the riddle of the dream and to trace the dream to normal psychic operations.
