 Note the similarity between Hayek’s view and the view expressed by John Rawls in “Two Concepts of Rules” (1955). Hayek and Rawls both understood what is involved in a practice having utility. To use Rawls’s example, the practice of baseball is defined by procedural rules rather than by end-state principles of distributive justice. To have a practice at all, we must be dogmatic (Hayek would say) about how many strikes a batter should get.
