Reviewed by: Reforming the Law of Nature: The Secularization of Political Thought, 1532–1689 by Simon P. Kennedy Francis J. Beckwith KENNEDY, Simon P. Reforming the Law of Nature: The Secularization of Political Thought, 1532–1689. Edinburgh: Edinburgh University Press, 2022. ix + 125 pp. Cloth, $110.00 In this monograph Simon P. Kennedy offers an account of the desacralization of politics in the West by critically examining the works of five central figures in the Protestant Reformed tradition: John Calvin (1509–64), Richard Hooker (1554–1600), Johannes Althusius (1557–1638), Thomas Hobbes (1588–1679), and John Locke (1632–1705). He dedicates a chapter to each thinker. The core of Kennedy's thesis is that desacralization is the result of a shift in the way modern thinkers like Hobbes and Locke reimagined the nature of natural law. The medieval tradition, having found its fullest expression in the work of St. Thomas Aquinas, saw natural law as one of four different types of law: eternal law (the eternal plan of creation in the mind of God), natural law (the rational creature's participation in the eternal law), human law (civil laws that are derived from the natural law), and divine law (the Old and New Testaments). According to Kennedy, the eventual desacralization of politics was set in motion with the development of arguments for natural rights that relied on a natural law that was in [End Page 553] practice severed from eternal law. But in that case, our political institutions—which are founded on the natural law—are purely human constructions and thus entirely secular. The usual story is that the Protestant Reformation constituted the decisive break with the medieval tradition and that it was the political theology of the reformers and their immediate successors that made the secularization of politics nearly inevitable. Kennedy wants to push back against that story. He argues, quite convincingly, that Calvin, Hooker, and Althusius, all Reformed Protestants, were in continuity with their medieval predecessors. Although Calvin is often depicted by his contemporary followers—especially among American Evangelicals—as hostile to the natural law tradition, Kennedy marshals an impressive case that shows that classical natural law seemed almost second nature to Calvin. My own sense is that the confusion over Calvin is the result of his contemporary readers expecting him to use the vocabulary of an Aquinas or a Duns Scotus. But not finding that vocabulary, they conclude that he rejected the natural law. Kennedy dispels that confusion by showing that Calvin in fact was fully committed to the four types of law absent the technical jargon of medieval scholasticism. Hooker and Althusius, writes Kennedy, continue in that tradition, though with a bit of a twist that some argue portends to Hobbes and Locke. Hooker and Althusius use the language of contract to account for the origin of certain aspects of political life. But Kennedy insists that it is a mistake to interpret them as proto-contractarians (as one finds in Hobbes and Locke), for they still held that the natural law participates in the eternal law, and that any agreements employed in the service of political life are under the authority of, and guided by, the natural law. One could argue, then, that these "contracts," like constitutions and treaties, are nonstatutory manifestations of the human law, which is perfectly consistent with classical natural law. So like Calvin before them, Hooker and Althusius were, as Kennedy puts it, theistic political naturalists. Hobbes and Locke are a different story. According to Kennedy, they both defended desacralized views of politics, with Hobbes being the more extreme of the two. Although I think he is correct in that assessment, I am not sure he locates the cause of the desacralization in the right place. For example, he says that because for Locke politics is artificial and not natural—that is, it is the result of a social contract to insulate members of society from the instability of a state of nature—politics is desacralized, even though God is the ultimate source of the natural law. But it is not clear how that in and of itself desacralizes politics. After all, Aquinas, the paradigm case of a classical natural lawyer, held...
