According to the standard analysis, humor theories can be classified into three neatly identifiable groups:incongruity, superiority, and relief theories. Incongruity theory is the leading approach and includes historical figures such as Immanuel Kant, Søren Kierkegaard, and perhaps has its origins in comments made by Aristotle in the Rhetoric. Primarily focusing on the object of humor, this school sees humor as a response to an incongruity, a term broadly used to include ambiguity, logical impossibility, irrelevance, and inappropriateness. The paradigmatic Superiority theorist (...) is Thomas Hobbes, who said that humor arises from a “sudden glory” felt when we recognize our supremacy over others. Plato and Aristotle are generally considered superiority theorists, who emphasize the aggressive feelings that fuel humor. The third group, Relief theory, is typically associated with Sigmund Freud and Herbert Spencer, who saw humor as fundamentally a way to release or save energy generated by repression. In addition, this article will explore a fourth group of theories of humor: play theory. Play theorists are not so much listing necessary conditions for something’s counting as humor, as they are asking us to look at humor as an extension of animal play. (shrink)
