 On this point, Kant compares the enjoyment of joking and wit to the enjoyment of games of chance and the enjoyment of music. In all three the pleasure is in a “changing free play of sensations,” which is caused by shifting ideas in the mind. In games of chance, “the play of fortune” causes bodily excitation; in music, it is “the play of tone,” and in joking, it is “the play of thought.” In a lively game of chance, “the affections of hope, fear, joy, wrath, scorn, are put in play … alternating every moment; and they are so vivid that by them, as by a kind of internal motion, all the vital processes of the body seem to be promoted.” In music and humor, similarly, what we enjoy are bodily changes caused by rapidly shifting ideas.
