• Sommario/riassunto: A common presupposition in contemporary moral and political philosophy is that individuals should be provided with some basic threshold of goods, capabilities, or well-being. But if there is such a basic minimum, how should this be understood? Dale Dorsey offers an underexplored answer: that the basic minimum should be characterized not as the achievement of a set of capabilities, or as access to some specified bundle of resources, but as the maintenance of a minimal threshold of human welfare. In addition, Dorsey argues ; that though political institutions should be committed to the promotion of this minimal threshold, we should reject approaches that seek to cast the basic minimum as a human right. His book will be important for all who are interested in theories of political morality.
