Natural Law Theory: Contemporary Essays ed. by Robert P. George (review)

146 BOOK REVIEWS Natural Law Theory: Contemporary Essays. Edited by ROBERT P. GEORGE. Oxford: Clarendon Press, 1992. Pp. 371. $39.95 (cloth). As the editor of this volume, Robert P. George points out in his foreword that this hook is yet another manifestation of the renewed and growing interest in natural law theory. But why this recent increased interest in natural law theory? What purpose is this theory supposed to serve, or in what way do its proponents see it as an improvement on existing theories? First of all, it must be noted, as the variety of essays in this volume makes abundantly clear, that natural law theory, as it is presently conceived, most certainly does not represent anything like a unified, single theory of tightly knit principles and conclusions. In the present volume one can easily see a half-dozen or more different approaches to natural law theory. So different in tone and spirit are some of the essays that one can easily wonder if they have enough in common even to classify them as " family resemblances." But if they all in their different ways do indeed evidence, as the editor claims, an increased awareness of and interest in natural law theory, the question immediately arises, why this increased interest? What problems do the advocates of these theories hope to solve by them or what questions do they think their theories will better address than the theories currently in place? First of all, one may make a division which places the theories, however divers~ among themselves, into two general groups. The first of these groups wishes natural law theory to function as a general approach to morality. For this group natural law does the work of a moral theory. In this group I would place the essays of Joseph Boyle, Robert George, Russell Bittinger, John Finnis, and Hadley Arkes (probably). The second group uses natural law theory as a way of determining the connection between moral law and positive law or legal theory. The essays of Jeffrey Stout, Neil MacCormick, Jeremy Waldron, Michael Moore, Lloyd Weinreb, Joseph Raz, and Ernest Weinrib fall into this second category. In all there are twelve essays in this volume. Space will not permit me to give a detailed analysis and critique of each. At most I can only indicate very briefly some of their more salient features. The book is divided into four parts, the first of which is titled "Natural Law, Practical Reasoning and Morality." In the very illuminating first essay of this section, "Natural Law and the Ethics of Traditions," Joseph Boyle undertakes to clarify the question of the relation of natural law theory to tradition. Certain approaches to moral theory currently popular BOOK REVIEWS 147 which are called virtues ethics, of which Alasdair Macintyre would he an example, claim that natural law theory is tradition-dependent. If Macintyre and other virtues ethicists are correct, then since natural law theory is culture-hound, and since the culture in which it was horn and flourished, medieval culture, has irretrievably retreated into the pages of history, then natural law theory is equally dead, of interest, if at all, only in an antiquarian way. Boyle carefully points out that there is more than one sense of being tradition-dependent. It is true that natural law theory is tradition-dependent in the sense that it did indeed come into existence in a particular historic epoch and that its language and thought do indeed express the period of its flourishing, i.e. the medieval period. But this, Boyle is careful to point out, does not mean that its validity and meaning were exhausted with the end of that culture. Rather the tradition is a living tradition so that its rich resources can continue to be exploited as that tradition is enlarged by its application to present day moral problems. Boyle's conclusion then is that in some senses natural law is indeed dependent on an ancient and medieval tradition, hut not so totally dependent that it has lost all validity for contemporary moral theory. In the contribution by Robert George, "Natural Law and Human Nature," George tries to defend Germain Grisez's version of natural law...
