This book is a wide-ranging collection of essays that makes the case for the humanities as central to our self-understanding, for theory as the latest incarnation of a perennial concern with the relation between words and things, and for the ancient as constitutive of the modern. Theory Does Not Exist: Comparative Ancient and Modern Explorations in Psychoanalysis, Deconstruction, and Rhetoric makes a strong argument for a comparative approach to what we term "theory" today. It argues that our disciplinary boundaries create artificial divisions between philosophy, rhetoric, and literature, which historically would not have been recognized and have come to function as conceptual straitjackets. These essays contend that a concerted engagement with the crucial texts in these debates over the last 2500 years not only offers a better understanding of the issues involved but also provides the necessary political, ethical, and existential tools for fashioning a better and more inclusive life. They offer extended readings of Plato, Cicero, and Sophocles, as well as Derrida, Foucault, Irigaray, Kristeva, Zizek, and Lacan. Theory Does Not Exist offers a full-throated defense of the humanities and crucial counterarguments against the reduction of education to the vocational and the operational.
