Many people assume that what morally justifies private ownership of property is either individual freedom or social welfare, defined in terms of maximizing personal preference-satisfaction. This book offers an alternative way of understanding the moral underpinning of private ownership of property. Rather than identifying any single moral value, this book argues that human flourishing is property’s moral foundation. It develops a theory that connects ownership and human flourishing with obligations. Owners owe obligations to members of the communities that have enabled the owners to live flourishing lives by cultivating in their community members certain capabilities that are essential to leading a well-lived life. These obligations are rooted in the interdependence that exists between owners and their community members, a condition that is inherent in the human condition. Obligations have always been inherent in ownership. The human flourishing theory explains why owners at times owe obligations that enable their fellow community members to develop certain necessary capabilities. This book considers implications for a wide variety of property issues of importance both in the literature and in modern society. These include questions such as: When is a government’s expropriation of property legitimate? May the owner of a historic house destroy it without restriction? Do institutions that owned African slaves or otherwise profited from the slave trade owe any obligations to the African American community? What insights may be gained from the human flourishing concept into resolving current housing problems like homelessness, eviction, and mortgage foreclosure?
