L. Nandi Theunissen develops a non-Kantian account of the value of human beings. Against the Kantian tradition, in which humanity is absolutely valuable and unlike the value of anything else, Theunissen outlines a relational proposal according to which our value is continuous with the value of other valuable things. She takes the Socratic starting point that good is affecting, and more particularly, that good is a notion of benefit. If people are bearers of value, the proposal is that our value is no exception. Theunissen explores the possibility that our value is explained through reciprocal relations, or relations of interdependence, as when-as daughters, or teachers, or friends-we benefit others by being part or constitutive of relationships with them. She also investigates the possibility that we can be said to stand in a valuable relationship with ourselves. Ultimately, in The Value of Humanity, she proposes that people are of value because we are constituted in such a way that we can be good for ourselves in the sense that we are able to lead flourishing lives. Intuitively, a person matters because she matters to herself in a very particular sort of way; to appropriate a phrase, she is a being for whom her life can be an issue.

To treat some human beings as less worthy of concern and respect than others is to lose sight of their humanity. But what does this moral blindness amount to? What are we missing when we fail to appreciate the value of humanity? The essays in this volume offer a wide range of competing, yet overlapping, answers to these questions. Some essays examine influential views in the history of Western philosophy. In others, philosophers currently working in ethics develop and defend their own views. Some essays appeal to distinctively human capacities. Others argue that our obligations to one another are ultimately grounded in self-interest, or certain shared interests, or our natural sociability. The philosophers featured here disagree about whether the value of human beings depends on the value of anything else. They disagree about how reason and rationality relate to this value, and even about whether we can reason our way to discovering it. This rich selection of proposals encourages us to rethink some of our own deepest assumptions about the moral significance of being human.
