 A third approach to the justification of rights might be called “contractual.” Here rights are characterized neither as naturally fitting for independent beings nor as tools to promote the best state of affairs. Rather, rights define principles that would be chosen by properly situated and motivated agents agreeing to the basic terms of their relations (e.g., principles chosen in Rawls’s original position, or principles within Scanlon’s contractualism that no one could reasonably reject). The fact that these principles would be agreed to under the specified conditions is their justification.
