This is a critical intervention into the key conceptual dissensions between contemporary Continental philosophy's three most influential thinkers. The writings of Lacan, Deleuze and Badiou stand at the heart of contemporary thought. While the collective corpus of these three figures contains a significant number of references to each other's work, these are often simply critical, obscure, or both. Lacan Deleuze Badiou guides academics working in philosophy, psychoanalysis and critical theory through the sensitive moments in their respective work and identifies the passages, connections and disjunctions that underlie the often superficial statements of critique, indifference or accord. This is the first book to examine Lacan, Deleuze and Badiou together. It reconstructs a fundamental conceptual history of Badiou, Deleuze and Lacan's influences and intellectual context. It identifies and examines the key themes in contemporary European thought: the event, time and truth. It shows how Deleuze and Badiou have followed and contravened the Lacanian intervention without reverting to pre-Lacanian positions.
