 Critically, there are two sets of relevant individuals (N and N*). The first set is the representative choosers (N) constructed in the “device of representation” such as the original position (Rawls 1996, 27). The second set (N*) is composed of real individuals whose terms of interaction are to be guided by the contract/agreement. If the deliberations of the contractors (N) are to be relevant to the actual participants (N*), the reasoning of the former must, in some way, be shared by the latter. There is, however, considerable debate about what it means for reasons to be shared in this sense (see  Public Reason  and  Public Justification).  The other main parameter in the model is the deliberative setting (M), in which the model choosers (N) endorse some rules, principles, or norms (R).
