In his elegant and accessible new book, Law's Quandary, Steven Smith groups our various senses of what is real for us into ontological families: the mundane; the scientific, including mathematics; and the religious. These supply "lumberyards," as it were, for thought and discussion about the world and action in it. Law itself is not one of them. Those involved in law, as citizens or professionals practicing law or speaking for or about law, are presented in the book as looking out from law to the ontological resources available in the lumberyards he describes.
