Though wit-making is an excellent means of obtaining pleasure from the psychic processes, we know that not all persons are equally able to make use of it. Wit-making is not at the disposal of all, in general there are but a few persons to whom one can point and say that they are witty. Here wit seems to be a special ability somewhere within the region of the old "psychic faculties," and this shows itself in its appearance as fairly independent of the other faculties such as intelligence, phantasy, memory, etc. A special talent or psychic determination permitting or favoring wit-making must be presupposed in all witmakers.
It has seemed to us that the pleasure of wit originates from an economy of expenditure in inhibition, of the comic from an economy of expenditure in thought, and of humor from an economy of expenditure in feeling. All three modes of activity of our psychic apparatus derive pleasure from economy. All three present methods strive to bring back from the psychic activity a pleasure which has really been lost in the development of this activity. For the euphoria which we are thus striving to obtain is nothing but the state of a bygone time, in which we were wont to defray our phychic work with slight expenditure. It is the state of our childhood in which we did not know the comic, were incapable of wit, and did not need humor to make us happy.
Wit and Dream
The most important difference lies in heir 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 distortions. 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 distortion 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 preponderantly to guard against pain, while wit serves to acquire pleasure; in these two aims all our psychic activities meet.
As we know that displacements in dream-work point to the influence of censorship of conscious thought, we will consequently be inclined to assume that an inhibiting force also plays a part in the formation of wit when we find the process of displacement among the techniques of wit. We also know that this is commonly the case; the endeavor of wit to revive the old pleasure in nonsense or the old pleasure in word-play meets with resistance in every normal state, a resistance which is exerted by the protest of critical reason, and which must be overcome in each individual case. But a radical distinction between wit and dreams is shown in the manner in which the witwork solves this difficulty. In the dream-work the solution of this task is brought about regularly through displacements and through the choice of ideas which are remote enough from those objectionable to secure passage through the censorship; the latter themselves are but offsprings of those whose psychic cathexis they have taken over through full transference. The displacements are, therefore, not lacking in any dream and are far more compresensive. They not only include the deviations from the trend of thought, but also all forms of indirect expression, especially the substitution for an important but offensive element by one indifferent and seemingly harmless to the censorship, which then looks like a most remote allusion to the first; they also include substitution through symbols, comparisons, or trifies. It is not to be denied that parts of this indirect representation really originate in the foreconscious thoughts of the dream-as, for example, symbolical representation and representation through comparisons-because otherwise the thought would not have reached the state of the foreconscious expression. Such indirect expressions and allusions, whose reference to the original thought is easily detectable, are really permissible and customary means of expression even in our conscious thought. The dream-work, however, exaggerates the application of these means of indirect expression to an unlimited degree. Under the pressure of the censor any kind of association becomes good enough for substitution by allusion; the displacement from one element to any other is permitted. The substitution of the inner associations (similarity, causal connection, etc.) by the socalled outer associations (simultaneity, contiguity in space, assonance) is particularly conspicuous and characteristic of the dream-work. 
Wit and Dream-Work
Absurdity in wit frequently stands for derision and criticism in the thought behind the witticism, wherein the wit-work follows the dream-work.
