In a series of philosophical discussions and artistic case studies, this book attempts to map out an affirmative and specifically materialist attitude to modern and contemporary art. The volume begins with the mapping out of the philosophical terrain 'beyond representation', and beyond the so-called crisis of representation (deconstruction). The argument is made for a return to aesthetics - an aesthetics of affect - and for the theorisation of art as an expanded and complex practice. The second half of the volume stages a series of encounters between specific Deleuzian concepts - the virtual, the minor, the fold, etc. - and the work of artists that position their work outside of the gallery or 'outside' of representation - Robert Smithson, the Situationists, Gerhard Richter, etc. Attention is also given to notions of a critical art practice, and to art's political and ethical potentiality. At stake in such encounters is less the development of a 'Deleuzian' approach to art, and more an experiment in doing Deleuze by taking his concepts into other milieus - and allowing these 'possible worlds' to work back on the philosophy.
