In the first volume of his History of Sexuality, 'The Will to Knowledge', Foucault weaves together the most influential theoretical account of sexuality since Freud. Now, this is the first reading guide to Foucault's dense and sometimes confusing text. Mark Kelly systematically unpacks the intricacies of Foucault's dense and sometimes confusing exposition, in a straightforward way, putting it in its historical and theoretical context. He looks at the book, its structure and philosophical significance, and corrects several key mistranslations in the only available English version of the 'Will to Knowledge'.
