Federico Testa has written a masterful book. By shedding light on the Foucault-Canguilhem relationship, he provides us with new conceptual tools to address crucial issues such as the politicization of life and the ambiguous nature of the norm as both a normalizing and a creative force. Read it-you won't be disappointed!

In the new Golden Age of Foucault studies, Federico Testa stands out as one of the finest scholars of his generation. This book is a model of informed, detailed, adroit, systematic, and lucid exegesis, which recaptures Foucault's originality, rearticulates his positions, and re-establishes his importance as an essential thinker for our times.

Testa provides a brilliant account of the linked dynamics of normative subjection and transformation, through his meticulous analyses of Foucault and Canguilhem. With stunning erudition, Testa illuminates the political and ethical possibilities that emerge from this joint philosophical encounter for both diagnosing and challenging our current politics of the living.

The most important study of the exchange of ideas between Foucault and Canguilhem, and a significant re-reading of each thinker's work in the light of the other. Testa is a vital guide to contemporary discussions of life, norms and politics through this compelling, powerful and persuasively argued book.
