First published 10 years ago, Manuel DeLanda's Intensive Science and Virtual Philosophy rapidly established itself as a landmark text in contemporary continental thought. DeLanda here draws on the realist philosophy of Gilles Deleuze to the domain of philosophy of science. As well as contemporary philosophical insights, the book also tackles new developments in geometry, complexity theory and chaos theory to bring new insights to our understanding of a scientific knowledge liberated from traditional ideas of essence. Now available in the Bloomsbury Revelations series, this edition includes a new preface by Delanda, revisiting the themes of his book ten years on.
