One of the most innovative and brilliant philosophers of his generation, but largely neglected until he was brought to public attention by Gilles Deleuze, Gilbert Simondon presents a challenge to nearly every category and method of traditional philosophy.Psychic and Collective Individuation is undoubtedly Simondon's most important work and its influence, clearly felt in Stiegler and DeLanda, has continued to grow. David Scott provides the first full introduction to this work, which will inspire as well as instruct philosophers working in Continental thought, philosophy of science, social theory and political philosophy.
