This book, a sequel to the first volume of Deleuze's Philosophical Lineage (2009), presents studies of 16 key figures drawn on by Deleuze, ranging from Lucretius to Schelling through to Foucault. Each chapter introduces the work of the thinker in question, explains the context in which Deleuze draws on this work and discusses the contribution that it makes to the development of Deleuze's own ideas.
