Book excerpt: This book discusses the equating of human lives with the material and argues that pricing lives lies at the core of the political. Indeed, as in Plato or Hobbes as well as in the Weberian ethics of responsibility, measurement is considered to be one of the central features of the political. This book argues that this measure relies primarily on two goods: human lives and interests. It also argues that the material equivalence to lives is twofold. Such equivalence is a double equation, as we pay for lives and we pay with lives. This double equation is constitutive of the measurement upon which the political equilibrium of a society depends and, as such, is constitutive of the political. The book adopts two approaches: one explanatory and the other normative. First, its purpose is to explain the nexus between existential goods and material goods and includes a thorough analysis of several case studies drawn from contemporary politics both domestic and international. Second, it discusses normatively the material valuation of human lives and the human value of material goods. The book relies upon interdisciplinary thinking as the material equivalent to lives is not only extremely relevant for political theory and philosophy, it is of great relevance for law. Great works of literature such as Shakespeare's plays are also excellent political illustrations of the importance of pricing lives we can learn from. Value attribution is an important question in the social sciences, notably in sociology, history and international relations.
