Abstract

A rational moral code must satisfy the condition of completeness. This same condition applies to a set of moral rights, where it takes the form of requiring that all the rights in that set be compossible: that their respective correlatively entailed duties be jointly fulfillable. Such joint fulfillability is guaranteed only by a set of fully differentiated individual domains. And if moral rights are to play any independent role in moral reasoning - any role logically independent of the values that bring persons into conflict - those domains must be determined by rules which are not derived from those values.
