'What are the tools that make it possible to manage? How do we make use of them, control them and to what effect? These are the fundamental questions that Chiapello and Gilbert address in a book that is as useful as it is fascinating. It is one that has much to teach not only scholars of management and organizations but also those want to think deeply about just what technology does.' Wendy Nelson Espeland, Northwestern University, Illinois
'Organised along the distinction between different paradigms and based on illuminating empirical examples, this unique book comprehensively restores the theoretical, epistemological and methodological foundations of the diverse ways of knowing and inquiring on management tools and on tools of government. This brilliant tour de force is a must-read for all students and academics in the field of management, sociology, organisation theory and public policy and for all those fascinated by the power of instruments at the heart of capitalism, science and politics.' Philippe Bezes, Centre national de la recherche scientifique and Sciences Po
