It has often been noted that opponents of the doctrine of natural law sometimes claim that it is no accident that its principal elaborators and defenders have been Christians who attempt to forge a doctrine that harmonizes reason and revelation, nature and grace. But, the argument goes, natural law theorists achieve that harmony by claiming that reason knows things about nature that wise and reasonable nonbelievers fail to see there. So it is interesting to see one who is a believer and, at least in appearance, a defender of the doctrine of natural law admitting the validity of the nonbeliever's objection, at least on one major point.
