What does contemporary French poetry do to the subject? This book examines the means and effects of the subject's transmutation into various processes of (de-)subjectivation by looking at the works of four contemporary writers: Christian Prigent, Dominique Fourcade, Olivier Cadiot and Hubert Lucot. The author explores their work in the context of Gilles Deleuze's philosophy, building a critical apparatus – a 'poetics of becoming' – that informs close readings of poems and prose. Moving beyond established criteria of classical literary criticism, the book both offers a comparative discussion of Deleuze's notions of literature and provides new insights into French writing, addressing the political dimension of contemporary poetry from the perspective of current theoretical radicalism.
