Laughter

This book first arose out of a passage in Borges, out of the laughter that shattered, as I read the passage, all the familiar landmarks of my thought. . . breaking up all the ordered surfaces and all the planes with which we are accustomed to tame the wild profusion of existing things, and continuing long afterwards to disturb and threaten with collapse our age-old distinction between the Same and the Other.

—Michel Foucault, The Order of Things: An Archaeology of the Human Sciences, qtd. in Judith Butler's Gender Trouble, p. 139
