 Thomson alleges that specificationists cannot explain the requirements that John apologizes to and compensates you, since on the specificationist view there is no right of yours that he has violated when he consumes your food. Thomson prefers the view that there really are conflicts of rights, and suggests that we should speak of a “defeated” right as being permissibly “infringed” (instead of “violated”), leaving residual obligations on the infringer. Frederick (2014) chases down some specificationist replies to these objections, and concludes that although moral rights are strong moral considerations, they are only pro tanto. Liberto (2014) develops a more sophisticated specificationist position, which is critiqued by Montague (2015). Mullins (forthcoming) offers a logical framework of practical reasoning that claims to capture the dynamics of the debate over specification.
