Notoriously, natural law means many things to many people. Natural law is discussed quite differently in the fields of ethics, law, and theology; it is employed quite differently in the spheres of political rhetoric, churches, and academia; it has been used quite differently in the eras of ancient Rome, medieval Europe, the Enlightenment, and the postmodern West; and something akin to natural law appears, with quite different associations, in the religious traditions of Christianity, Judaism, Islam, and Hinduism. In some contexts natural law refers to God's moral law. In other contexts natural law consists of norms that can be discerned solely through human reason. In still other contexts natural law describes rules that are naturally embedded in the physical world.
1 I am ignoring the second-order normativity involved in the claim that one ought to obey the law, in the traffic-light case.

3 John Finnis taught at Oxford from 1966 to 2010; he remains an honorary fellow at University College, Oxford. From 1995, Finnis has also held a faculty appointment at the University of Notre Dame.
4 George has served on the United States Commission on Civil Rights, the President's Council on Bioethics, the United States Commission on International Religious Freedom, and as a Judicial Fellow of the Supreme Court of the United States, among other positions.
5 Also closely aligned with the position of Finnis and George is the work of Catholic theologian Germain Grisez. For Grisez's comprehensive statement on moral theology, see his The Way of the Lord Jesus, 3 vols. (Chicago: Franciscan Herald Press, 1983–1987).

25 “[A]ction, which is rooted in the body, is always already oriented to the meaning that is inscribed in human nature by the Creator. It finds its beginning in passion, which is precisely that reaction which reveals to man the possibility of a new and greater fullness that freedom is called on to acknowledge and embrace in the light of reason” (Melina, Searching for a Universal Ethic, 299).
26 Most notably, Anver Emon argues that the International Theological Commission is particularly careless in its treatment of Islam because it points to the Mu‛tazilite theological school to demonstrate the Islamic interest in natural law, but the Mu‛tazilite school is now generally considered heterodox (Emon, Searching for a Universal Ethic, 128–29).
27 For an intellectual-historical rather than constructive engagement between these three traditions, see Brague, Rémi, The Law of God: The Philosophical History of an Idea (Chicago: University of Chicago Press, 2007)Google Scholar; originally published in French in 2005. Reference to Brague's compelling work is nearly absent from Natural Law; this absence is another reminder of the insularity of Anglophone natural law debates.

29 But see Finnis, Natural Law and Natural Rights, chapter 13, for an argument for the necessary role of God in such a natural law theory.

31 Finnis, John, “Prudence about Ends,” in Reason in Action: Collected Essays, vol. 1 (Oxford: Oxford University Press, 2011), 173–86CrossRefGoogle Scholar. In general, Finnis is much more open than is George to appreciating the role of the virtues and to resisting reasons fundamentalism.

33 It is essential to the biblical story that God is angry, jealous, suffering, and loving, to take but four examples.
34 Though note how VanDrunen sees the Christian church as a site where a higher, pre-eschatological moral order is enacted.

38 This is an unusual case because of the role of the Supreme Court Justice as part-judge, part-intellectual; it is likely untrue for lower court judges. Clarence Thomas wrote about natural law theory before he joined the court, causing a controversy at his confirmation hearings.
