  Not much directly will be said about these positive arguments for permitting organ sale since they rely on more fundamental and general questions in moral and political theory that cannot be tackled within the confines of a piece on organ sale (within SEP, see the entries on libertarianism,  privacy and medicine, and  property and ownership). Later sections will indirectly address these arguments, though, because many of the objections to sale considered could, if successful, overturn any defeasible presumption in favour of allowing ‘self-ownership’ to prevail.
