 The relation in the second inquiry is less discussed. Specific theories of the setup of the social world include theories of convention, law, collective acceptance, structure, practices, and more (see  section 4).  A theory of law, for instance, may propose that certain lawmaking systems are set up by specific beliefs and practices of members of the society. Here, a set of social entities—legislative systems—stand in some relation R2 to a set of other entities—member beliefs and practices. Perhaps the R2 relation (or relations) is the same as the R1 relation. Or perhaps it is different; this topic remains little explored.
