This article takes a critical look at the classic couplet of theories on the justification of rights, namely, the choice theory and the interest or benefit theory, where the two are understood to be in conflict. The argument is made that this couplet is best replaced with a new one, namely, a sophisticated rendering of the benefit theory coupled with the autonomy theory, such that any conflict is resolved. The latter two theories take different cases in justifying the attribution of (...) rights: The autonomy theory is concerned with justifying the attribution of rights to adult, rational, and competent subjects, arguing that this attribution requires a sufficiently autonomous claim by such subjects, while the benefit theory seeks to justify the attribution of rights to subjects who lack any of these three properties, meaning that they cannot be considered adult, rational, or competent.
