Smith 1994 contains an interesting informal discussion of conflicting obligations, defeasibility, violability and contrary-to-duty conditionals. |
It has multiple aspects, including the denial of autonomy and subjectivity and the ideas of ownership, fungibility, and violability. |
According to Nussbaum, there are seven features are involved in the idea of objectification: instrumentality, denial of autonomy, inertness, fungibility, violability, ownership, denial of subjectivity. |
Thus this puzzle also places not only deontic conditional constructions, but the violability of obligations, at center stage. |
