The Fruitfulness of Normative Concepts

Abstract Can philosophical concepts do real work in improving our world? Should we, when evaluating competing understandings of concepts like ‘justice,’ ‘empowerment,’ and ‘solidarity,’ take into account whether these different understandings can actually help us to fight injustice, empower the oppressed, and promote solidarity between people? The Fruitfulness of Normative Concepts is the first book-length attempt to argue that the answer to both of these questions is an emphatic “yes.” In doing so, it provides a bold new defense of a tight relationship between philosophical theory and practice. The book advances the view that moral and political philosophers should be interested in the “fruitfulness” of normative concepts—how well they help us to solve practical problems that we inevitably face as human beings interacting with one another. This view has broad implications for a number of important contemporary philosophical debates that the book examines, including debates over the nature of moral motivation, the duties of the global affluent to the global poor, the nature of justice in diverse multicultural societies, ideal versus non-ideal theory in political philosophy, and conceptual engineering. Drawing on cutting-edge research in moral psychology and adjacent fields, the book also demonstrates that we now have the scientific tools to concretely evaluate the practical value of moral and political concepts. It issues an important call to continue developing the use of these tools and methods to produce more philosophically and scientifically significant work on the distinctive value of normative thought and practice.
