CHAPTER 9
REASON AND
NATURAL LAW
STEPHEN POPE
THE centre of theological ethics is God-the (ineffable one', (the nameless one', and (holy mystery', who remains always incomprehensible to human reason (see Rah ner 1985: 46-7, 65-6). The conclusions reached through exercising the powers of human intelligence will therefore have a secondary significance to the kind of knowledge communicated in revelation and experienced in faith. The God of Christian theological ethics, the concern of this essay, is revealed as Creator and Redeemer. Faith in this God leads one to affirm that an ordering wisdom lies
behind both the inherent logos of the natural world and the explicit revelation
communicated in Scripture and the Christian tradition. Scripture, the written record of God's self-communication to humanity, is the single most important source for theological ethics. Yet, 'since theology is generated by faith seeking understanding, theological ethics employs the various cognitive capacities that we group together under the term (reason'. Scholars of course differ, sometimes vehemently, over what (reason' means, how it functions, and what role it ought to play within theological ethics (see Gustafson 1978). The doctrine of (natural law' constitutes a particular subset of the larger question of the place of reason and philosophy in theological ethics. Its adherents tend to be Roman Catholic, but not always so. Its meaning is anything but unproblematic and obvious. In spite of having been subject to wave after wave of criticism in the history of philosophy and theology, natural law continues to appeal to those who believe that ethics must be grounded in being and the moral life based on what is
REASON AND NATURAL LAW 149
good for human beings. Periodic disclosures of human wickedness and horrors lynchings, secret police abductions, or death squad assassinations-reawaken our sense of the importance of objective moral standards to which evil-doers can be held accountable. Reminders of human goodness inspire gratitude for positive moral capacities bestowed on us by the Creator and elicited by grace. Theological ethics is drawn to natural law for two fundamental reasons. First, it advances a form of moral realism which affirms that moral standards are based in reality, and in this sense 'objective', rather than manufactured by human decisions. Second, some ethicists are attracted to natural law for its universal scope and its claim to apply to all human beings-. rich as well as poor, conqueror as well as conquered, men as well as women. Yet the ancient and medieval contexts from which natural law doctrine emerged are now long gone. It is thus helpful to keep in mind that concepts taken out of context can generate misunderstanding and confusion unless explicated with care and interpreted in ways that make sense to new audiences. Consider the meaning of 'natural'. When the ancients understood the good life to be 'according to nature', they meant according to what is best, most noble, or most excellent in human nature. Moderns, on the other hand, understand 'nature' according to the meth odology of the natural sciences as what occurs with some frequency under natural conditions. Classical philosophy and modern science refer to 'nature' in entirely different senses, but references to both continue to shape contemporary moral Ie', and (^) discourse. Even to understand what is meant by 'natural law' presents a significant e Rah (^) challenge for us. Jowers (^) This essay begins with a brief discussion of the historical origins of the notion of jnd of (^) natural law and its medieval development, then proceeds to examine its modern ;od of (^) transformations, more recent theoretical developments, and contemporary chal Jr and (^) lenges. Since not every aspect of such a complex topic can be examined adequately 'ill lies (^) in an essay-length treatment, this essay will focus on how 'nature' functions dation (^) normatively within natural law ethics.

specific knowledge of their details. The virtue of prudence, or practical wisdom,
habitually leads the moral agent who possesses it to act in a 'fitting' manner (Aquinas 1948: I-II, 57, 2, 5). Moral reasoning can go astray either through ignor ance of the particulars of a case or by ignorance of the general moral principle (or principles) relevant to it (Aquinas 1948: I-II, 76, 1). The process of moral reasoning results in an act of conscience, a particular judgement to act or refrain from acting. Good judgements are based on proper understanding and lead to reasonable decisions. Reason is competent to control, and proper control is exercised in light of reason shaped by the right purposes (Aquinas 1948: I-II, 18, 9). Being directed to an appropriate end, of course, is not simply a matter of reasoning about it. Appetites must be well disposed to their proper end through the 'habits' of the moral virtues-not only prudence, but also justice, temperance, and fortitude. If they are not disposed to their proper end-if 'right reason' is not complemented by 'right desire'-then moral reasoning itself will be derailed (Aquinas 1948: II-II, 47, 4). Natural law is thus 'rational' but not 'rationalist'. Thomas's understanding of 'nature' and 'reason' converged in his account oflaw. Thomas understood 'law' as an ordinance of reason, ordered to the common good, made by one who has care for a community, and communicated publicly (Aquinas 1948: I-II, 90, 4). 'Law' governs in analogous ways the created world ('eternal law'), human behaviour ('natural law'), particular human political communities (,tem porallaw' or 'positive law'), and the Christian life ('divine law'). The human person is made in the 'image of God' and endowed with free choice. Since each person has the capacity to choose to accept (or to reject) the moral principles of the eternal law, Thomas defined natural law as 'the rational creature's participation in the eternal law' (Aquinas 1948: I-II, 91, 2). ('Natural' for Thomas did not mean 'automatic' or 'mechanistic'.) This participation is both reasonable and natural:. each person must use his or her reason to discover what accords with 'right reason' in any particular situation, and 'right reason' always conforms to the order inscribed by the Creator in nature. Practical reason proceeds from indemonstrable or self-evident principles. The most fundamental obligation, as we have seen, is to 'do good and avoid evil'. The principles of the natural law take as their 'matter' natural inclinations: the inclin ation for existence common to all beings, the generic inclinations to reproduction and sexual relations shared by all animals, and the specifically human inclinations to political life, truth seeking, and spirituality held in common by all human beings. Practical reason thus applies the principles of the natural law to the expression of natural human inclinations expressed in different domains of exist ence-sex, marriage and family, life, communication, property, and so forth. Two additional features of practical reason must be kept in mind. First, practical reasoning, unlike speculative reasoning, deals with individual and contingent matters, and therefore its judgements are not characterized by absolute necessity (see Aquinas 1948: I-II, 3, 6 ad 2). They are true 'for the most part', but do not
152 STEPHEN POPE
always hold. Moral principles therefore need to be interpreted with sensitivity to the particular nuances of concrete cases, not applied rigidly and mechanistically (see Aquinas 1948: I-II, 96, I, 6). Second, this process of derivation acknowledges a gradation in the authority made by different kinds of moral claims. What is taken by one community to be an application of the natural law can be dispensed with in another community when it is determined to be detrimental to the common good, justice, and virtue (see Aquinas 1948: I-II, 100, 8; see also I-II, 97, 6; 97, 4 ad 3). A change in circumstances can mean that the secondary precepts of the natural law do not apply in these cases; it does not imply, however, that the secondary precepts are invalidated (see Kossel in Pope 2002: 169-93). Since human nature includes body and soul, the human good is material as well as spiritual, intellectual, and moral. Human nature and the good proportionate to it, like both the political community and the universe as a whole, is structured hierarchically. Human nature is oriented to lower goods (of the body), to relatively higher goods (of the soul), and to an ultimate good (God). Practical reason is equipped to grasp the essentials of this order, though it also benefits from the detail, clarity, and assurance of revelation. Most importantly, divine law orients the person to an otherwise unknown destiny-the Beatific Vision-but rather than obliterating the naturally human in favour of an exclusively other-worldly good, this end calls forth its deepest potentialities. The moral life orders the lower powers to serve the higher, and both to contribute to love of God and love for neighbour. Acts of virtue are rewarding in and of themselves; vicious acts constitute their own punishment. The wicked do not always recognize their own misery, but this kind of ignorance is in itself an added dimension of self-inflicted punishment. The thief, liar, and murderer work contrary to their own happiness not only in the afterlife but also in this one. The saint, on the other hand, achieves true beatitude even when suffering.
NATURAL LAW CHALLENGED
The Thomistic interpretation of the natural law has been subjected to a wide variety of significant 'criticisms throughout the history of philosophy and theology. Rather than examine each particular criticism in detail, a task that would require volumes, I will confine myself to a broad overview of a few important features of this challenge. After this brief overview, I will consider various ways in which natural lawyers have responded to these challenges and then make an assessment of the current state of the question.
154 STEPHEN POPE
Evolutionists do not infer, however, that we are fated to be immoralists. In fact, the opposite is the case: they argue that our only hope lies not in the rescue operation of a transcendent deity but in the willingness of courageous human beings to assume responsibility for building more fair, just, and tolerant commu nities. Instead of legitimizing selfishness, clannishness, and chauvinism, most evolutionary moralists strive to endorse mainstream liberal values such as liberty, individual rights, and tolerance. Because there is no natural law, in other words,
moral order has to be created by human agents. Morality allows us to override,
at least to some extent, the complete indifference of nature to human affairs (see Nitecki and Nitecki 1993; Rose 1998; O'Hear 1997).
CONTEMPORARY ApPROACHES
TO THE NATURAL LAW
All ethical theories operate on the basis of a description, implicit or explicit, of the morally relevant traits of human nature; relatively more sound ethical positions are based on relatively more adequate accounts of human nature. Conversely, defective presuppositions about human nature can cripple an ethical theory. Contemporary advocates of natural law ethics work within the context of a cultural world that lacks any consensus about an objective basis for moral claims. Natural law is challenged by historicism as well as by naturalism. Naturalism, we have just seen, denies that there is either a transcendent purpose to life or a metaphysical basis for affirming that any moral claims are true and binding on all human beings. Historicism claims that reality is composed only of individual entities, and that it is therefore impossible to make claims that apply to all people. Because human beings exist only as particular individuals living at particular times and in particular cultures, there can be no universal moral claims. Both naturalism and historicism work with the underlying premiss that the world is valueless and purposeless, except when values and purposes are created by human choices. There is no shared humanity, only a vast collection of individuals from the same species locked in various modes of competition against one another. Natural law ethicists respond to this challenge in a variety of ways. One strategy suggests a return to the golden age of natural law. Those who defend what can be called, for lack of a better term, 'revived Thomism' continue to produce transla tions and commentaries on Thomistic texts and their modern commentators (see, e.g., McInerny 1982, 1992). A second approach to natural law focuses on the exercise of practical reason within the context of specific problematic cases. The 'public philosophy' developed

In fact, (^) by John Courtney Murray, SJ, pursues natural law as the basis of moral discourse in e rescue (^) pluralistic societies governed by representative democracy (see Murray 1960). ; human (^) Murray and other admirers of Pope John XXlII's Pacem in Terris critically appro commu priate modern insights into the nature of human rights and combine them with the n, most (^) older Thomistic focus on duties and the common good (see Hollenbach 2003). s liberty, (^) A third, revisionist position interprets natural law in light of the 'historical r words, (^) consciousness' promoted by the Second Vatican Council (see, e.g., McCormick werride, (^) 1989). Revisionist natural law holds that the rightness or wrongness of acts depends n affairs on whether they are beneficial or harmful to the person, rather than on their conformity to nature. Identifying an act as 'contrary to nature' indicates its 'relative disvalue', but not necessarily its moral impermissibility. An act is only morally wrong when, other things being equal, there is no proportionate reason justifying it (McCormick 1989: 134). Two other innovative approaches to natural law are particularly important today: the new natural law theory and the personalist natural law theory.

ext of a (^) A new approach to natural law has been developed partly in opposition to both [ claims. (^) revisionist natural law and revived Thomism. Germain Grisez, John Finnis, and [ism, we (^) their colleagues constructed a 'new natural law theory' (see Finnis 1980; Grisez ife or a 1983), because they did not believe that the received theory was any longer .ding on (^) philosophically viable. Their theory holds that the 'first principles of practical dividual reason' give rationality to the process of moral decision making. Its first principles

Rather than draw moral norms from some set transla (^) of facts about human nature, the new theory derives particular moral norms entators from more general moral norms.

authority than revelation (see Barth 1961: 3-31; Niebuhr 1979 [1935]: ch. 5, but modified in 1941: I; but also Hutter and Dieter 1998). The pope's account of natural law drew from Scripture, but also built on Thomistic precedents, and incorporated modern notions of human dignity and human rights. This account of natural law was developed on the distinctively personalist and Christocentric anthropology presented by the Second Vatican Council's 'Pastoral Constitution on the Church in the Modern World': 'only in the mystery of the incarnate Word does the mystery of man take on light' (Flannery 1988: 922). Yet the pope did anything but break away from the natural law-on the contrary, he assumed its relevance even when he engaged in scriptural exegesis on moral matters. The encyclical Veritatis Splendor enunciated familiar themes from the natural law tradition. Natural law is 'inscribed' in the heart of every person, grounded in the human good, and prohibits 'intrinsically evil acts' (John Paul II 1993: par. 81). Reason is a gift of God, but takes its proper orientation from faith especially today, when knowledge of the natural law has been blurred in the 'modern conscience'. Unlike the emphasis of 'public philosophy' and the 'new natural law theory', the pope's ethic repeatedly insisted that an adequate grasp of the natural law depends on revelation, faith, and adherence to the teachings of the magisterium. As an 'expert in humanity', the Church has the most profound grasp of the principles of the natural law, and also the best vantage point from which to understand its secondary principles and their application. This is not to say that the pope gave up on reason or regarded natural law as less intrinsically intelligible than did other natural lawyers. He, like the others, would have agreed with the revisionist denial that there are any 'mysterious ethical norms which are simply impervious to human insight' (McCormick 1989: 204). John Paul II continued to reaffirm the ancient view of moral standards as inherently intelli gible. The increasing appeal of human rights around the world (by ordinary people, if not always by their governments) confirms the accessibility of the moral law. Natural law qua human rights provides the basis for the infusion of ethical principles into the political arena of pluralistic democracies. It also provides criteria for holding accountable criminal states or transnational actors that violate human dignity by engaging, for example, in 'genocide, abortion ... deportation, slavery, prostitution... [and] degrading conditions of work which treat laborers as mere instruments of profit' (John Paul II 1993: par. 80, citing Gaudium et Spes, par. 27). Natural law holds out the best resource for countering both amoral relativism and the tyrannical misuse of power (see John Paul II 1995: par. 70). The pope's personalist natural law theory gave an important place to fixed, knowable, and clear moral rules that apply to communities as well as to individ uals. Its treatment of reproductive issues is illustrative. States as well as couples, no matter what difficulties and hardships they face, 'must abide by the divine plan for responsible procreation' (John Paul II 1995: par. 97). Sounding a theme from Pope Pius XI and Pope Paul VI, John Paul II warned his listeners that 'The moral law
158 STEPHEN POPE
obliges them in every case to control the impulse of instinct and passion, and to respect the biological laws inscribed in their person' (1995: par. 97). Natural law thus proscribes not only artificial contraception, abortion, infanticide, and euthanasia, but also newer biomedical procedures regarding experimentation with human embryos and human cloning. Natural law also provides moral criteria for assessing economic and political systems. Though there is no one correct model of an economic or political system, natural law does require that any given economic or political order affirm human dignity, promote human rights, foster the unity of the human family, and support mean ingful human activity in every sphere of social life (see John Paul 1987: par. 41, in O'Brien and Shannon 1992: 424-5; John Paul II 1991: par. 43, in O'Brien and Shannon 1992: 471-2). John Paul II's personalist interpretation of natural law has been criticized on several grounds. First, it stressed law at the expense of reason and nature. As the Dominican Thomist Herbert McCabe observed of Veritatis Splendor, 'despite its frequent references to St. Thomas, it is still trapped in a post-Renaissance morality, in terms of law and conscience and free will' (McCabe 1994: 67; see also Spohn 1995). Second, the pope was criticized for an inconsistent eclecticism that did not coherently relate biblical, natural law, and rights-oriented language in a synthetic vision. He switched from one kind of argument to another without indicating how the different parts are integrated into a coherent whole. Third, he was charged with a highly selective and ahistorical understanding of natural law. Thus, what he described as 'unchanging' precepts prohibiting intrinsically evil acts have at times been changed. As John Noonan put it, in the long history of Catholic ethics, one finds that 'what was forbidden became lawful (the cases of usury and marriage); what was permissible became unlawful (the case of slavery); and what was required became forbidden (the persecution of heretics)' (Noonan 1995: 194). Fourth, critics argued that John Paul II had an underdeveloped sense of 'historical consciousness', and therefore consistently slighted the contingency, variability, and ambiguities of historical particularity (see Curran 2002: 61-6). This can lead to an absolutist and legalistic reading of the natural law that obscures the need for the virtue of prudence. Fifth, this approach to natural law also led feminists to accuse the pope of failing to attend sufficiently to the oppression of women in the history of Christianity and to downplay the need for change in the structures of the Church (see Cahill 1998; Traina 1999). To his credit, the pope was more concerned with the fundamental basis of the natural law than are proponents of most of the other positions examined here. His approach was theological and ontological: nature is creation, the human creature must be understood in personal terms, and the person must always act in accord ance with the plan of the Creator. This theological understanding of creation, however, is never informed, co-ordinated with, or even placed in contact with scientific ways of viewing nature. This is not because the pope denied the proper
160 STEPHEN POPE
1981: 175 f.). A person is a 'story telling animal' whose identity and purposes come notthrough nature but through the narratives of living traditions. His next major work, Whose Justice? Which RationalitY. moved beyond Aristotle to an appropri ation of Thomas Aquinas's virtue ethics, thus inclining him towards a greater appreciation of the moral significance of the natural law and human nature (MacIntyre 1988: 181, 194 f.). MacIntyre's more recent writing, Dependent Rational Animals (1999), employs naturalistic observations about natural functions of animals (notably dolphins) as a means for thinking about natural purposes. 'I now judge that 1 was in error in supposing an ethics independent of biology to be possible,' writes MacIntyre (1999: p. x). But here MacIntyre draws from biology to underscore the reality of human vulnerability and disability in relation to which the 'virtues of acknowledged dependence' (1999: ch. 10) must be developed and exercised. Unfortunately, MacIntyre's interest in animality is usually restricted to various forms of weakness or disability. He does not reflect on how the behavioural traits of animals are related to larger questions of natural purposes. He thus begins, but does not complete, the development of a new teleological view of human nature upon which a revitalized natural law could be built. The continued development of natural law ethics depends on re-establishing a sense of the purposefulness of the natural world in general and of human nature in particular. Given the magnitude of this task, an essay of this sort can provide only rudimentary outlines of how such reflection might proceed. First, we need to reflect more carefully on the way in which the cosmos is structured to sustain moral purpose-i.e., 'teleologically'. The term 'teleology' is used in so many ways that it is nearly impossible to avoid misunderstanding (see Ayala 1970 and 1989); yet natural law ethics has no alternative but to use it or something like it. Natural law ethicists need to be clear that they are not suggesting that every event in the universe exists to produce a predetermined goal: e.g., that the occurrence of mutations in DNA is directed by some sort of biological planning agent. The purpose of the universe exists in and through the interaction of chance and necessity that constitute its overall design. The universe has been 'tine-tuned' to give rise to at least one planet with physical conditions that allow for the emergence and maintenance of life. The Earth provided conditions that were hospitable first to beings marked by some elemental forms of information processing, then to beings capable of consciousness, and finally to beings capable of self-consciousness. The earliest forms of life gave rise to organisms with increased capacities for movement, sensitivity, awareness, and responsiveness. Organisms moved only by chemical reaction gave rise to organisms moved by apprehensions, drives, and emotions. Spontaneity was complemented by restraints imposed by the social ordering of animals living in groups. Increased environmental demands called forth expanding behavioural repertoires, increas ingly complex emotional responses, and more and more sophisticated mechanisms of information processing.

This broad evolutionary context gave rise to a particularly intelligent primate, Homo sapiens, whose social life, even in its earliest phases, was made possible by complex forms of symbolic communication, especially language. Human intelli gence, like that of other primates, was originally suited to simple problem solv ing-e.g., how to move across complex terrain to get food or how to fend off threats from aggressors-but our ancestors gradually gained capacities of heart and mind that allowed them to be captivated by wonder and to reflect on questions for their own sake. Music, art, poetry, and religion came to express 'contemplative' as well as 'practical', or socially functional, purposes. A closely related development occurred morally: the necessity of making choices for instrumental purposes gave rise to the capacity to care about goods and persons for their own sakes. The development of the human sense of compassion and awareness of justice came to extend moral concern beyond one's own circle of 'reciprocators' to any human being in need or any person suffering from injustice. Some aspects of the basic human sense of fairness expand upon a proto-moral sense of equity shared with other social primates (see de Waa11996; Brosnan and de Waal 2003). The universal appeal of the golden rule testifies to this moral devel opment in the species and to the natural roots of justice. The emergence of human cognitive and moral abilities was also accompanied by the emergence of a capacity for religious self-transcendence. The culmination of the evolutionary process consists in the ability of the cosmos, through human beings, to understand its existence as gift, to respond to its Creator with awe, gratitude, and fidelity, and to undertake responsibility for the well-being of those spheres of creation within
which it is possible to do so.
The word 'teleology' is used here in h\7O senses. First, the 'cosmic evolution' of the universe as a whole is teleological in that it has given rise to increasingly complex structures and forms of life from which a species capable of intelligent and loving behaviour has emerged. Second, human nature is also teleological in that it is naturally oriented both to specific goods and, more importantly, to the good as such. Moral systems around the world bear witness to this natural orientation. Human nature is inclined to a variety of goods. The human good includes, as Thomas would put it, 'external goods' and 'goods of the body', and therefore ethics must take into account the considerable pre-rational, biological roots of human nature (see Porter 1999: ch. 1). Biology considers a range of goods that comprise part of what Thomas called 'temporal happiness', but this end is, at its best, radically incomplete, since the biological does not encompass even psychological, social, or cultural goods, let alone moral and religious ones, in their own right. Evolutionary theory, then, will always fail to satisfy those who seek in it a complete account of the natural law. Indeed, evolutionists need to be subjected to critical scrutiny when they present a kind of quasi-natural law argument suggesting that the values of our own particular culture are best suited to address our natural needs as human beings (see Beckstrom 1993 and Buss 1994).

the array of our evolved proclivities in ways that accord with 'right reason'. The moral life is a matter of gradually shaping these emotional responses into forms that promote the human good. This view of reason and nature provides a way of interpreting the moral law. A right way of acting is not ethically obligatory or legitimate simply because it is 'natural', in the scientific sense, as 'evolved' or 'genetically based', but it is obligatory because it accords with what is good for human beings, considered comprehen sively. The obligatory character of morality-the 'law'-binds the person to moral standards that promote the well-being, or flourishing, of the person and his or her community. It is wrong to murder, to be sexually unfaithful, to steal, to lie, and to cheat, because doing so undermines the good of both self and others. General norms are not matters of arbitrary taste or idiosyncratic preferences, but reflect judgements about structures of living that promote human flourishing. Our basic orientation to the good is not extinguished by wrongdoing: even liars resent being lied to, and those who steal get morally outraged when stolen from. Virtues and law, like reason and nature, are generally complementary to one another. In natural law ethics, true moral objectivity is achieved in concrete acts through the exercise of the virtue of prudence. What is objectively binding in a particular situation, in other words, is what is most in keeping with the first principle of practical reason: do good and avoid evil. General moral knowledge includes various beliefs about which aspects of our inherited behavioural repertoire ought to be approved of, acted upon, and promoted-and which ought to be inhibited, sublimated, or closely monitored. It also includes general knowledge of which kinds of acts tend to undermine the human good and which kinds of acts promote it, but moral decision making only succeeds when attention is focused on concrete goods and evils at stake in particular situations. The virtue of prudence is lacking when moralists insist on adhering to rules that, in concrete situations, damage human lives. Rather than prescribing a universal and exhaustive moral code proper for all times and all people, our understanding of natural law must be dynamic, flexible, and open to new developments as a result of changing human circumstances. The virtue of prudence functions most effectively when it enables the agent to perceive the morally salient factors at stake in concrete human experiences. It is in and through concrete experience that people discover, appropriate, and deepen their understanding of what constitutes true human flourishing. Interpretations of these experiences are influenced by membership in particular communities shaped by particular stories. Discovery· of the natural law, Pamela Hall notes, 'takes place within a life, within the narrative context of experiences that engage a person's intellect and will in the making of concrete choices' (Hall 1994: 37). Our grasp of the natural law and our ability to exercise the virtue of prudence are tutored in community. A properly social understanding of human nature under scores the dependence of virtue generally on community. People are formed and
164 STEPHEN POPE
trained in virtue by the stories and exemplars handed down through traditions. Life in community shapes the affections, imagination, and practical rationality through which moral standards are interpreted (see Spohn 1999). This returns us to the importance of Scripture, tradition, and the Church, all of which play critically important roles in shaping identity and one's sense of the full range of what is meant by human flourishing. Advocates of natural law ethics, then, draw not only from science and moral philosophy, but also from Scripture and tradition in their effort to develop a more appropriate, precise, and comprehensive account of genuine human flourishing. Only in this way will contemporary natural law reasoning contribute to the development of an ongoing moral tradition, rather than simply perpetuate time-worn platitudes and abstract, universal rules.
