 One approach, which is suggested by Kant, seeks to explain normativity in terms of norms that one could rationally will to serve as requirements incumbent on all agents (1785 [1981]). This can be described as a matter of self-legislation, since each person is viewed in effect as herself legislating these norms to serve as requirements on all agents. On this view, as Kantians develop it, the content of everyone’s “self-legislation” must be the same, assuming relevantly similar circumstances. For the view assumes that there are standards of rational willing that constrain what anyone could will to serve as requirements incumbent on all agents.
