This last contribution, the explanation of wit-work in the first person, though still hypothetical, strictly speaking, ends our interest in wit. There still remains a short comparison of wit to the more familiar dream and we may expect that, outside of the one agreement already considered, two such diverse mental activities should show nothing but differences. The most important difference lies in their social behavior. The dream is a perfectly asocial psychic product. It has nothing to tell to anyone else, having originated in an individual as a compromise between conflicting psychic forces it remains incomprehensible to the person himself and has therefore altogether no interest for anybody else. Not only does the dream find it unnecessary to place any value on intelligibleness, but it must even guard against being understood, as it would then be destroyed; it can only exist in disguised form. For this reason the dream may make use freely of the mechanism that controls unconscious thought processes to the extent of producing undecipherable disfigurements. Wit, on the other hand, is the most social of all those psychic functions whose aim is to gain pleasure. It often requires three persons, and the psychic process which it incites always requires the participation of at least one other person. It must therefore bind itself to the condition of intelligibleness; it may employ disfigurement made practicable in the unconscious through condensation and displacement, to no greater extent than can be deciphered by the intelligence of the third person. As for the rest, wit and dreams have developed in altogether different spheres of the psychic life, and are to be classed under widely separated categories of the psychological system. No matter how concealed the dream is still a wish, while wit is a developed play. Despite its apparent unreality the dream retains its relation to the great interests of life; it seeks to supply what is lacking through a regressive detour of hallucinations; and it owes its existence solely to the strong need for sleep during the night. Wit, on the other hand, seeks to draw a small amount of pleasure from the free and unencumbered activities of our psychic apparatus, and later to seize this pleasure as an incidental gain. It thus _secondarily_ reaches to important functions relative to the outer world. The dream serves preponderately to guard from pain while wit serves to acquire pleasure; in these two aims all our psychic activities meet. VII WIT AND THE VARIOUS FORMS OF THE COMIC
