She was educated at Harvard and Cambridge and re- ceived a Ph.D. from Harvard. She has taught at Columbia, Harvard, Princeton, Brandeis, the University of Göttingen, and the University of Chicago, and has held visiting positions at the Ecole de Hautes Etudes en Sciences Sociales in Paris, the University of Vienna, and Oxford. She is a fellow of the American Academy of Arts and Sciences and a member of the Berlin-Brandenburg Academy of Sciences. Her numerous publi- cations include Classical Probability in the Enlightenment (1988); and Won- ders and the Order of Nature, 1150–1750 (1998, with Katharine Park), both of which were awarded the PŠzer Prize of the History of Science Society; and The Moral Authority of Nature (2003, coedited with Fer- nando Vidal). 636-p.qxd 4/19/2004 2:00 PM Page 373 I. THE MORALITY OF NATURAL ORDERS: THE POWER OF MEDEA Introduction: Natural and Moral Orders There are few Enlightenment projects that now seem more obsolete, even archaic, than the attempt to ground moral order upon natural or- der. Long before our current debates over evolutionary ethics and the morality of genetic technologies, philosophers found the appeals of Jacques Turgot, the Marquis de Condorcet, the Physiocrats, Jean- Jacques Rousseau, and many other lesser eighteenth-century lights to the moral authority of nature almost incomprehensible. Circa 1850 John Stuart Mill, for example, wrote that invocations of nature and the natural were among “the most copious sources of false taste, false philos- ophy, false morality, and even bad law.”1 Or as the Russian novelist Ivan Turgenev put it only a few years later: “she [nature] knows nothing of art or liberty, as she does not know the good.…”2 The milder form of this critique argues that nature does not qualify for moral agency, much less moral authority: nature neither deliberates nor dictates; the natural and the moral belong to different ontological categories. Even environ- mental ethicists who have argued that nature should be the object of moral solicitude have stopped short of making it the subject of moral authority. The more severe version of the critique points out that many of nature’s actions (e.g., earthquakes) would be judged by almost any moral standard as positively criminal. To quote John Stuart Mill again: “In sober truth, nearly all the things which men are hanged or impris- oned for doing to one another, are nature’s everyday performances.”3 Alexander Pope’s famous couplet from the Essay on Man strikes us as not 1 John Stuart Mill, “Nature” (comp. 1850–58), in Three Essays of Religion (1874), in Es- says on Ethics, Religion and Society, ed.

Instead, I wish to explore how nature could ever have been endowed with moral authority and why that au- thority still exerts such a powerful, if covert, pull upon our modern sen- sibilities, despite innumerable critiques and cautions against conšating “is” and “ought,” against “naturalizing” judgments that are really social and political, and against anthropomorphizing “Nature,” designated with a capital N and often with a feminine pronoun. Indeed, the very frequency with which philosophers, political theorists, and cultural critics of all stripes must admonish us about committing the naturalis- tic fallacy of smuggling moral prescriptions into natural descriptions is cause for raised-eyebrow remark. No amount of trenchant criticism of this or that instance of the naturalistic fallacy seems sufŠcient to root it out. To discover allegedly “natural” motives for a crime mitigates its severity (and often the severity of punishment); conversely, the reproach of the “unnatural” has not lost its sting, whether it is applied to a cruel mother or to cloning. Nor does the abundant evidence drawn from the annals of natural history concerning behaviors no one would want to emulate—consider the mating habits of the praying mantis or the mas- sacre of drones by worker bees—apparently diminish the charm of other cases trotted out to legitimate some other human practice by analogy with, for example, ducks or ants. Why, one wonders further, do so many cultures cast moral precepts for humans in the form of stories about an- imals, as in the case not only of Aesop’s fables and medieval bestiaries but also of hundreds of recent children’s books? This resilience in the face of protracted criticism and a mountain of empirical counterexamples is prima facie evidence that we are in the grip of metaphysical demons. Certain categories of thought and sensi- bility—and the two are intimately and signiŠcantly intertwined— shape the way in which experience is parsed, evidence is weighed, and judgments are formed. As a mere historian, I am under no illusions as to my power to exorcise these demons. Unlike psychoanalysis, history does 4 Alexander Pope, An Essay on Man, Being the First Book of Ethic Epistles to Henry St. John, L. Bolingbroke (London: John Wright for Lawton Gilliver, 1734), I.286, p. 22. 636-p.qxd 4/19/2004 2:00 PM Page 375 [Daston] The Morality of Natural Orders 375 not claim that tracing the genesis of a neurosis or a pattern of thought and sensibility will ipso facto liberate one from either. At best, histori- cal analysis can show the contingency of such subterranean patterns and drag them into the light of conscious scrutiny. It can neither refute nor replace them. The former is largely futile in the case of metaphysics, no- toriously resistant to argument and evidence; the latter is properly the work of creative metaphysicians, who are even rarer than great poets or scientists, perhaps because they must combine the talents of both in making up a new world that holds together. What history can do is to excavate deeply held intuitions, in the sense of both revealing their ori- gins and uncovering them to view. This exercise might be described as a kind of history of the self-evident: the sources and multiplicity of our most deeply held assumptions and irrefragable intuitions, their coming into being and passing away. This is what I would like to do for the moral authority of nature. I shall argue that that authority derives from at least three different con- ceptions of nature and that most post-Enlightenment critiques have ad- dressed only one of them. This is because the character of moral authority itself underwent a sea-change in the seventeenth and eigh- teenth centuries, so that older (and still persistent) appeals to a different kind of authority based on a different kind of nature no longer appeared to be even candidates for rebuttal. The Šrst, venerable conception of na- ture is literally speciŠc: that which makes something the kind (or species) of thing it is, its ontological identity card, if you will. This is the primary meaning not only of the English word “nature” and its cog- nates in many other modern European languages, but also of its Latin root natura, as well as of the ancient Greek word physis. This speciŠc sense of nature is closely related to a second kind of natural order con- ceived as local, pertaining to the šora, fauna, and landscape of a particu- lar place. Both speciŠc and local natural orders are richly variable, cornucopias of types and topographies. They are regular, but not deter- ministic, orders based on “what happens always or most of the time,” in Aristotle’s phrase, rather than on inexorable physical necessity. The third, more modern conception of nature is by contrast comprehensive, uniform, and universal. It embraces the entire nonhuman universe and is deŠned by unexceptionable regularities that are everywhere and always the same. If the metaphor for the order of comprehensive nature is “law,” that which was applied to the orders of speciŠc and local na- tures was “custom,” implying a contrast of moral orders resonant in 636-p.qxd 4/19/2004 2:00 PM Page 376 376 The Tanner Lectures on Human Values associations for early modern Europeans all too familiar with clashes be- tween the customs of localities and the laws of absolutist monarchs. The one natural order was heterogeneous, local, and, within limits, mutable; the other was homogeneous, global, and eternal. Because only the third order, both moral and natural, has remained intellectually visible and viable, and because only the traits of universal- ity, uniformity, and permanence are still admitted as titles to any kind of moral authority (hence the modern bogey of relativism), I shall con- centrate in these lectures on the Šrst two older orders of nature: speciŠc, local, custom-governed nature—or rather natures, since they always come in the plural within these orders.
