I propose the Shared Presupposition Norm of Joking (SPNJ) as a constitutive norm of joke-telling. This norm suggests that a person should only tell a joke if they believe their audience shares the presuppositions—both explicit beliefs and implicit inferential connections—upon which the joke turns. Without this shared understanding, the audience would lack the necessary comprehension to appreciate the joke. I defend this norm in an analogous way to Williamson’s defense of the Knowledge Norm of Assertion by demonstrating that it explains (...) a number of patterns of joking behavior. If SPNJ is indeed a constitutive norm of joking, it provides an epistemological foothold. Jokes function as conversational explicatures serving an epistemically diagnostic function, revealing implicit and perhaps disavowed inferential dispositions of the joking community. This norm does not teach us about the subject matter of the joke, but instead illuminates the language games of the joke teller and audience. (shrink)

In this article, I consider the standard interpretation of the superiority theory of humor attributed to Plato, Aristotle, and Hobbes, according to which the theory allegedly places feelings of superiority at the center of humor and comic amusement. The view that feelings of superiority are at the heart of all comic amusement is wildly implausible. Therefore textual evidence for the interpretation of Plato, Aristotle, or Hobbes as offering the superiority theory as an essentialist theory of humor is worth careful consideration. (...) Through textual analysis I argue that not one of these three philosophers defends an essentialist theory of comic amusement. I also discuss the way various theories of humor relate to one another and the proper place of a superiority theory in humor theory in light of my analysis. (shrink)
