 For more robust realist conceptions of law, it’s difficult to predict whether the special initial conditions will emerge as lawlike. Necessitarian accounts like Pargetter’s (1984) maintain that it is a law that \(P\) in our world iff \(P\) obtains at every possible world joined to ours by a nomic accessibility relation. Without more specific information about the nature of the accessibility relations and the worlds to which we’re related, one can only guess whether all of the worlds relative to ours have the same special initial conditions. Nevertheless some realist theories offer apparently prohibitive criteria, so they are able to make negative judgments. For instance, “universalist” theories associated with David Armstrong say that laws are relations between universals. Yet a constraint on initial conditions isn’t in any natural way put in this form; hence it would seem the universalist theory would not consider this constraint lawlike.
