Perceiving an enigmatic relationship between madness, language, and literature, French philosopher Michel Foucault developed ideas during the 1960s that are less explicit in his later, more well-known writings. Collected here, these previously unpublished texts reveal a Foucault who undertakes an analysis of language and experience detached from their historical constraints.

Three issues predominate: the experience of madness across societies; madness and language in Artaud, Roussel, and Baroque theater; and structuralist literary criticism. Not only do these texts pursue concepts unique to this period such as the “extra-linguistic,” but they also reveal a far more complex relationship between structuralism and Foucault than has typically been acknowledged.
