The implications of recognizing property in our own excised body parts are vast and far reaching, involving ethical, legal and practical issues that cut across many aspects of modern social intercourse and legal regulation. Arguments both for and against such recognition are well rehearsed; enough has been written to fill a small library, or at least a large bookshelf. A significant portion of the work considers the role and impact of such recognition on human dignity. Indeed, given the special status accorded the human body, it is impossible to avoid human dignity and its interaction with the various choices presented by the adoption of a property model. However, reference to this general ethical value is of little assistance. Here, the ethical foundation of a property model is considered within the context of medical ethical four principles, namely autonomy, beneficence, non-maleficence and justice. If such a model promotes these principles, it can be ethically defended.
