Preface

THE PUBLISHER thinks that The Edge of Objectivity needs a new suit of clothes on its thirtieth birthday, and has asked for a preface to say how the work looks to me now that it has to face up to a second generation of readers. Naturally, I am delighted that the book and its author are alive, and apparently well, and I shall do my best to look at it objectively.1

The story begins with Galileo and the law of falling bodies. If I were rewriting it now, the opening scenes would still lie in Italy, but farther back, with the enterprises of a Brunelleschi, a Leonardo da Vinci, a Michelangelo, a Vasco da Gama, a Christopher Columbus. Theirs were doings animated by the same instinct that later formed a Galileo, namely, that knowledge finds its purpose in action and action its reason in knowledge, that if a problem can be solved, it should be solved, that if something can be done, it should be done. It has come to be my opinion that those behavior patterns, rather than the philosophical influence of Platonic idealism (which should not be eliminated from consideration, however, but only from preeminence) were what made the culture of the Renaissance in Italy the matrix wherein ancient and scholastic learning and technique were converted into modern science and engineering.

The persons just named include two voyagers, for a place in such a history should certainly be made for the expansion of the arena of science beyond the spherical triangle bounded in the fifteenth century by the Adriatic, the Portuguese coastline, and the Irish Sea. Clearly, the voyages of discovery then initiated a process of geographical and political dynamism that eventually acquired the vis viva to carry spacecraft to the moon. What relates the early voyages and their sequels to the history of science is that they were bearers of the civilization which through science came to dominate the world, at least till yesterday, for good and for ill. Further, what differentiates them from the random travels of antiquity, and of other civilizations, which produced only adventure, legend, or commerce, is that they were always involved with, though not perhaps motivated by, the problem of how the world is made—in a word (again), with knowledge. It would not be practical for me to write that book now, however, and this one will have to stand on its own feet, within its boundaries of intellectual history.

When it was published, in 1960, I made bold at the beginning of the bibliographical essay to express a hope that it might help to encourage the development of a professional approach to the history of science. It has since become apparent that my book was an early instance of such a movement already under way, for clearly the growth in range and sophistication of scholarship has proved much greater and more rapid than anyone then engaged in the subject could have foreseen. Even more clearly, its development has gone far beyond anything that could be attributed to the influence of any particular item in the literature, including this one.

Something may be said about the juncture, however. Those of us who were then writing on the subject at the outset of our own careers made up the first generation of scholars to devote themselves wholly to the history of science as a specialty in itself, one comparable to art history, for example, or (as I suggested at the time) to philosophy of science. An important literature already existed, of course, going back to the eighteenth and even to the seventeenth centuries. In large part, its content was philosophical, and its character programmatic, not to say prescriptive. Examples are the writings of Auguste Comte, Pierre Duhem, and Ernst Mach. Contributions of another sort derived from avocations of scientists themselves—Delambre on the history of astronomy, Chasles on the history of geometry, Sachs on the history of botany. There was also a strong philological element, particularly when the question concerned antiquity. Even George Sarton’s work consists mainly of a summons to the subject and the provision of bibliographical tools. All those approaches have their distinctive merits, of course, and their limitations.

Only in the time when this book was being written had scholars begun to incorporate the subject into the discipline of professional historiography, and only in the 1950s were formal courses of instruction beginning to be offered in colleges and universities. Students at the undergraduate level came in large part from the sciences and from engineering. It was from such a course of lectures that The Edge of Objectivity derived. At the same time, or soon after, advanced students in certain graduate programs began to receive training for the doctorate with a view to becoming historians of science on purpose, instead of by personal or professional accidents of the sort that had led their teachers at an early stage of careers already under way to the opportunities that the subject affords.

The bibliographical essay also tells how, when those fortunate accidents occurred in the late 1940s and early 1950s, the work of Alexandre Koyré on Galileo offered us a model of what exciting interest the critical history of scientific ideas might hold.2 I should equally have mentioned Arthur O. Lovejoy for the elegance and charm of The Great Chain of Being (1936), but somehow Koyré imparted a greater impetus to our thinking. So stimulating was his example, and so austere his taste, that one can only regard the influence as fortunate, although there have been critics who thought his mode of treatment over-intellectualized. Perhaps one might apply Comte’s law of the three stages of development in science to its historiography: theological in infancy, metaphysical in youth, positive in maturity. If so, Koyré’s appeal and its reflection in my book might be assigned to a moment of late youth, in the life of its author and of the discipline.

When the notion of reissuing this work arose, the publisher also asked, very reasonably, whether the bibliographical essay might be revised and brought up to date. Embarrassments of two sorts prevent my acceding fully to that request. The first is relatively trivial, and is that the bibliography was never intended to be exhaustive, even of the resources available to scholars in 1960. It pretends to be no more than a critical account of writings that I had found most suggestive in composing the book. That modest purpose would be lost to view in a revision. The second difficulty is insurmountable. Such has been the activity of scholarship in the intervening three decades that a review of the literature relevant to the topics discussed would be unmanageable in scale. A bibliographical essay adequate to the work on the career of Newton, for example, would be several times longer than the chapter treating his life and physics in the pages that follow. Readers wishing to pursue this, or any other topic I discuss, may consult the articles devoted to the appropriate figures in the Dictionary of Scientific Biography (1970–1980), which were based on, and often constituted, the latest scholarship at the time of publication. Each provides a full bibliography. The DSB may be supplemented, particularly for the 1980s, by the annual Critical Bibliography issue of the journal Isis. Let me here simply indicate the main sectors in which scholarship has been fruitful in the last thirty years and winnow out certain strategic items from the harvest.

A word should first be said about the Middle Ages, even though the period does not fall within the present purview, for the reason that scholarship has tended to smooth the transition between medieval and early modern science. David C. Lindberg has edited a collaborative overview.3 The inventiveness of European technology is now traced back beyond the Renaissance to innovations of builders and craftsmen in the high Middle Ages.⁴ The writings of A. C. Crombie argue that the origin of inductive reasoning and experimental method are to be found in the work of Robert Grosseteste and successors through the fourteenth century.⁵. The study of optics is seen to be continuous from al-Kindi to Kepler.⁶ Medieval statics and kinematics have assumed increasing importance both for the conceptualization and mathematicization of phenomena of force and motion. Marshall Clagett gives a comprehensive history, with extensive selection from the texts in translation, while Edward Grant provides an account of theories of space and the void.⁷ Anyone concerned with these subjects from antiquity through the seventeenth century should have recourse to E. J. Dijksterhuis, for whose book the only right word is magisterial.⁸

As for the period of the Scientific Revolution, our understanding of Galileo has improved through studies that tend to emphasize the experimental aspects of his work.9 What may have been the real, and secret, reason for his condemnation by the Church is the central problem of a fascinating study by Pietro Redondi vividly recreating the milieu, scientific, political, and ecclesiastical, wherein Galileo reasoned, quarreled, and wrote.¹⁰ On the mathematical side of the Scientific Revolution, Noel Swerdlow and Otto Neugebauer have collaborated on a treatise explicating Copernican astronomy, while Michael S. Mahoney has explored the significance of Fermat’s career for the background of modern analysis.¹¹ The actual practice of experimental philosophy and its relation to Hobbesian philosophy form the subject of Simon Shaffer and Steven Shapin. Leviathan and the Air Pump: Hobbes, Boyle, and the Experimental Life. Erudition and its conceptual transformation is the theme of Peter R. Dear’s study of Mersenne.¹² Important for this period, and not only for British science, is the publication of the correspondence of Henry Oldenburg, Secretary of the Royal Society.¹³

A topic that receives virtually no attention in my book, the alleged significance for science of magic and hermeticism, has attracted extensive and also intense interest, particularly during the revival of a fascination with the occult and with alternative ways of seeing nature in the countercultural movements of the late 1960s and early 1970s. That, to be fair, was not the only reason for the trend. The theme of winning power over nature occupies authors of books as various as Paolo Rossi’s admirable study of the origins of Francis Bacon’s philosophy, Keith Thomas’s book on the decline of magic in sixteenth- and seventeenth-century England, Frances Yates’s pioneering research on hermeticism, most notably in a work on Giordano Bruno, and Charles Webster’s account of the common understanding of science in England during the period of the Puritan Revolution.14 Medical elements are emphasized in scholarship devoted to alchemy and to the Paracelsists, whereas Harvey has been rescued, so to say, from Descartes, who made him a mechanistic physiologist, and restored to Aristotle.¹⁵ Harvey’s followers in Oxford form the subject of a book that peoples a research tradition with real investigators, rather than simply invoking the importance of the role they play in the making of science.¹⁶

Newton himself has not escaped exploration of the alchemical writings and utterances recorded in his manuscripts, nor the attentions of psychobiography.¹⁷ The signal matter, however, is Richard S. Westfall’s superb biography, comprehensive both scientifically and personally, Never at Rest.18 Newton’s unpublished correspondence and mathematical papers are now available in two complementary and splendid editions.¹⁹ In addition, I. Bernard Cohen has written a history of the production of the Principia and edited a variorum edition that is surely definitive, a project that he bagan in collaboration with Alexandre Koyré.²⁰ Finally, Alan Shapiro has published the Optical Lectures of 1670–1672 in the first volume of a projected edition of Newton’s writings on optics.²¹

It is fair to say that critics have consistently found the most suggestive chapter of my book to be the fifth, dealing with Science and the Enlightenment.²² The theme of tension between a rationalist and a romantic mode of reaction to the role of science in culture was in some sense recapitulated, and its psychological reality thus confirmed, by the tendency among cultural radicals in the 1970s to see science not as a liberation from ignorance and superstition, but as a force set against humanity, a disease of western civilization. It was curious that, although Marxism has always represented itself as the extension of science to the recognition of laws of historical development in society, the New Left then commingled a political with cultural hostility to exact science (although not, of course, to natural history, ecology, or organismic biology). In these respects, its position was identical with that of the Far Right in Weimar Germany.23

This instance of an emotional touching of the extremes compounds the paradox just mentioned, for in practice the resentment turned on the political role of science. The Marxist, and indeed the liberal, sense that science pertains historically to progressivism, while telling against conservatism and tradition, is widely shared. The notion does have a sociological foundation, but there is no basis for it either in political implications of the laws of nature, for they have none, or in the political actions of the professional community of science.²⁴ Whatever the private opinions of scientists, their civic role has normally been to provide the governing authorities with powers, while drawing authority and resources from the state for science. The relation of scientists to the state in modern times has been one of partnership rather than partisanship, whether for or against programs of particular political parties. In my view, this consideration is further evidence that science is intrinsically relevant to means and indifferent to the choice of ends.

To return now to my book, its next topic, the chemical revolution, has been reexamined in an issue of the recently revived companion to Isis, the monographic journal Osiris.²⁵ The background in practical chemistry, and particularly in pharmaceutical operations, was the subject of important earlier work by Henry Guerlac and others, while Frederic L. Holmes has published an account of the research on respiration that occupied Lavoisier in his last years.26 The Académie des Sciences in Paris has resumed publication of the long-interrupted correspondence of Lavoisier.²⁷ Worthy studies of Joseph Priestley and John Dalton have also appeared, and the theory of elective affinities has begun to be appreciated for its place in the developing comprehension of chemical bonding, as has the crystallographic model of the molecule.²⁸

As for nineteenth-century biology, it is a limitation that the conception of this book made no place for subjects other than those relating to evolutionary theory. In part, at least, that choice reflected the state of scholarship at the time it was written. In the intervening three decades, interest has continued to bear on evolutionary questions, both Lamarckian and Darwinian.²⁹ Ernst Mayr’s, The Growth of Biological Thought is a masterful treatment by a leader in modern evolutionary biology.30 Illuminating in a different way are certain studies that are not so much about the formation of theory as about the manner in which science was actually made, with respect particularly to the resolution of controversy in British geology and in German biology, to relations between physiology and medicine, and to the background of genetics and molecular biology.³¹

The opening paragraphs of the chapter on nineteenth-century physics deplore the paucity of the secondary literature. That situation has been much repaired, particularly in the last ten years. Enrico Bellone, A World on Paper, deals philosophically and quizzically with the central issues of physics in the framework of a Second Scientific Revolution.³² Studies of Coulomb, Malus, Ampère, Faraday, Maxwell, and Kelvin have appeared.³³ A new edition of Maurice Daumas’s Arago has been issued.34 Jed Buchwald treats the development of the wave theory of light in the early part of the century and electromagnetic theory at the end of it, while Stephen G. Brush gives a history of the kinetic theory of gases.³⁵ Peter Galison, in his book How Experiments End, brings the current preoccupation with the fine-grained activities of producing science to the historiography of physics.³⁶ Thomas S. Kuhn’s, Black Body Theory and the Quantum Discontinuity is a step-by-step analysis of how Max Planck arrived at the theory from which quantum mechanics took its departure.³⁷ Finally, Abraham Pais has contributed a physicist’s biography of Einstein, the publication of whose papers is at very long last under way.³⁸

That an excellent history of the science in America should treat rather the profession than the content of physics may be taken as an instance of a change in emphasis that has affected our entire discipline.³⁹ A large share of attention has shifted from the internal history of science in its ideas and concepts to the external history of science in its own institutions and its relation to society. Preoccupation with institutions was thought antiquarian and outmoded at the time my book was written. It has become respectable, and even central, largely through the influence of Thomas S. Kuhn’s Structure of Scientific Revolutions, which turns on the question of how the practice of science affects its content.40 Beyond that, or rather around it, the social history of science gathered strength from the heightening of social consciousness throughout the historical profession since the late 1960s, while its political history appeals to a related awareness of the importance that science has come to hold as a force in the world, both in the domestic affairs of nations and in international relations.

In my view, instances of this tendency that amount to a kind of sociopolitical reductionism may go too far. It would be absurd to deny that science is no longer a purely intellectual pursuit (that it ever was is a myth), or to shut one’s eyes to the enormous influence it exerts in education, the economy, politics, diplomacy, and warfare. But it appears to me that its role is to be studied in the intersections between technical and civic concerns, or between internal and external factors, and not by investing the body of scientific knowledge with the attributes of politics or the structure of society at large. That science partakes of those attributes in its organization is an incidental rather than an intrinsic aspect of its nature. Such, at any rate, is the approach of a book of my own, Science and Polity in France at the End of the Old Regime, which treats a context wherein science and the national state took on the importance for each other that they have held in rapidly increasing measure ever since.⁴¹

In closing, perhaps I ought to say a word about the theme of the present book. It incurred some criticism at the time of publication for the lack of a clear definition of objectivity. Since then it has met with some disfavor on the (not altogether consistent) grounds that, whatever objectivity means, no such attitude is attainable in this world of culturally conditioned existence and conflicting ideologies. As to the former charge, I have to admit that there is some justice to it, and would plead only that it is characteristic of works of history that, unlike works of philosophy, they may be more convincing in recreating parts or aspects of their subjects than they are in point of the theory or argument that animated their author at the time of writing. If I were writing this book again, even as a purely intellectual history, I would not insist so patently on objectivity as the common feature of scientific theories. I would be more inclined to use terms such as externalization of nature to describe the central cultural tendency of science, and alienation to evoke its consequence in sensibility. But though I hope I might write a subtler book, I do not believe it would be a different one thematically. It still seems to me that science has exacted a price, and the price is that anthropomorphic considerations of goal, purpose, suitability, and wish be eliminated from its formulations and statements. I still think that the intellectual history of science finds its sequence or direction in successive stages of that sometimes painful process.

For my taste, moreover, the price is worth paying. On the one hand, I also remain persuaded that science has been a potent, if not omnipotent, weapon in the battle against ignorance, superstition, dogma, and material deprivation. However two-edged the sword has felt since the discovery of nuclear fission, and however leaden a life preserver amid the rising tide of industrial pollution, respect for the human mind still requires us to believe that, though knowledge is dangerous, ignorance is more so, and that abating the ills accompanying science requires better-directed science rather than a retreat or a regression. For, on the other hand, I remain unpersuaded by the sort of statement I have heard from the lips of a noted anthropologist, to the effect that it makes as much sense to say, “Magic works,” as it does to say, “Science works.” The statement is one that might be subscribed to in a current school of interpretation—social constructionist as it is usually called—on the grounds that it is not by the nature of the world itself that we are given any reason for preferring one representation of its processes or structure over another, the Newtonian over the Aristotelian, the Darwinian over the creationist, the quantum-mechanical over the classical or relativistic, the germ theory of disease over the humoral. Like Taoism or Stoicism, or the beliefs about natural phenomena harbored by the Navajos or an African tribe in another century, these constructions are taken to be merely epiphenomena of a particular culture serving the purposes, economic or political, of some dominant group in certain circumstances, and it is by their sociocultural works that they are to be known and judged.

I would cite two sorts of evidence, not discussed explicitly in my book, to support the contrary proposition that science, though undoubtedly produced by individual persons and groups of persons in a social environment, has the capacity to transcend personality and circumstance in its effect within the historical process. The first has to do with the relation of science to the persons who create it, where there is a contrast to be made with the mode of creation of art and literature. It is obvious that Hamlet, the Gioconde, and the Mass in B-Minor would not exist if Shakespeare, Leonardo, and Bach had never lived. It is different with science, even the greatest science. The planets would still move subject to the inverse-square law of gravity if Newton had fulfilled predictions at his premature birth and died in infancy. Although no one else would then have written the Principia, it could be argued convincingly that others would then or soon have written down in one way or another everything in it that really mattered to classical physics. Much the same is surely true of nearly all the great contributions to modern science. No other evidence is needed beyond the well-known experience of virtually simultaneous discovery of almost all the important laws and of a host of minor phenomena and effects. It is all very well to say that convergent social forces are the explanation of simultaneous discovery, but they do have to converge on something. Moreover, although the introduction of a piece of science will bear the mark of its creator—Lavoisier’s clarity of mind, Maxwell’s playful imagination, Galileo’s haughty sense of drama—the personal element that went into the original formulation makes no difference to the practice of workaday science once it has left the hand of its creator, which is immediately. The personalities of science are full of interest, but it is a human, not a scientific, interest. The discovery itself must be verifiable and workable by any qualified person, if it is to be science at all.

So it is with the cultural context of discovery. I also remain persuaded that from the fifteenth or sixteenth century until very recently, science was a creation of European civilization, and of it alone among all the others that have seen the world. Together with the technology that attends it, science is, moreover, the one aspect of western civilization that the others have wanted to adopt. They have never wanted our political or social systems, our religions or philosophies, our arts or letters. Beginning with the Japanese, they have wanted science, and they can acquire it and operate it as well as we do in order to liberate themselves from constraints of many sorts, including us. Thus, though created out of personality and in culture, science is not then bound by personality or culture. It is impersonal and universal. I can think of nothing else of which that may be said. Perhaps it is a reflection that justifies describing science as objective, a body of knowledge made by persons, but made about the world and not about themselves.

There are other ways to find out about ourselves.
