 Gaus’s case for fine-grained “individuation” of proposals involves two arguments. We must justify at a level narrow enough to identify which forms of behavior are permitted or not. But we must justify at a level wide enough to see rules as governing classes of behavior (Gaus 2011, 122–125). This entry’s formulation of the PJP focuses on law \(L\) for brevity, and it acknowledges that public justification theorists work with other objects of justification.
