 Darwall (2012) argues that his second-personal theory of morality best explains the relation between duty-bearer and right-holder. (Yet see Vankieken 2019.) Cruft (2019) agrees that the directed duty-bearer is required by the nature of her duty to conceive of the right-holder second-personally, as “you, on whom I act.” Cruft then distinguishes natural and human rights, which are grounded largely by the good of the right-holder, from conventional rights, which are grounded by how they serve people or values besides the right-holder. Cruft argues that most property rights are conventional, yet seem to be natural in such a dangerously ideological way that we should speak of them as not rights at all, but rather merely as involving certain controllable duties of others.
