But now there appears another impulse which strives to set free pleasure by this identical process, even though from different sources it thus acts like the suppressed stream. What can be the result in such a case? An example can make this clearer than this schematization. There is an impulse to insult a certain person; but this is so strongly opposed by a feeling of decorum and æsthetic culture that the impulse to insult must be crushed. If, for example, by virtue of some changed emotional state the insult should happen to break through, this insulting tendency would subsequently be painfully perceived. Therefore the insult is omitted. There is a possibility, however, of making good wit from the words or thoughts which would have served in the insult; that is, pleasure can be set free from other sources without being hindered by the same suppression. But the second development of pleasure would have to be foregone if the insulting quality of the wit were not allowed to come out, and as the latter is allowed to come to the surface, it is connected with the new release of pleasure. Experience with tendency-wit shows that under such circumstances the suppressed tendency can become so strengthened by the aid of wit-pleasure as to overcome the otherwise stronger inhibition. One resorts to insults because wit is thereby made impossible. But the satisfaction thus obtained is not produced by wit alone; it is incomparably greater, in fact it is by so much greater than the pleasure of the wit, that we must assume that the former suppressed tendency has succeeded in breaking through, perhaps without the need of an outlet. Under these circumstances tendency-wit causes the most prolific laughter. Perhaps the investigation of the determinations of laughter will aid us in forming a clearer picture of the process of the aid of wit against suppression. But we see even now that the case of tendency-wit is a special case of the principle of aid. A possibility of the development of pleasure enters into a situation in which another pleasure possibility is so hindered that individually it would not result in pleasure. The result is a development of pleasure which is greater by far than the added possibility. The latter acted, as it were, as an _alluring premium_; with the aid of a small sum of pleasure a very large and almost inaccessible amount is obtained. I have good grounds for thinking that this principle corresponds to an arrangement which holds true in many widely separated spheres of the psychic life, and I consider it appropriate to designate the pleasure serving to liberate the large sum of pleasure as _fore-pleasure_ and the principle as the _principle of fore-pleasure_. _Play-pleasure and Removal-pleasure_
