Incompatibility
In correspondence with the incompatibility theory, wit is conceived at the moment of realization of incompatibility between a concept in a given situation and the real things that are supposed to be in that situation.
As the main object of the theory is not the incompatibility itself, but its implementation and determination, that's why it is very often called the incompatibility-resolution theory.
It was Francis Hutcheson who expressed an opinion in his "Thoughts on Laughter" (1725) that became a milestone (the common core) of the emerging theory of the comic, that is laughter as an answer to the receiving of incompatibility. Afterwards, Arthur Schopenhauer proposed a hypothesis of the incompatibility being in the middle between a concept and the real thing it represents. For example, Hegel was almost of the same opinion. Additionally, he suggested the idea of laughter totally negating a ridiculed object. On the other hand, Sigmund Freud viewed laughter as "economical phenomenon" that is to release "physical drive" that is mobilized by wrong or false anticipations.
As a matter of fact, complete formulation of the incompatibility theory is referred to Immanuel Kant.
