Decentering the Object in Technoscience

The list of persons and organizations who have contributed to this work is too long to include in full. But I would particularly like to mention and thank the following: British Aerospace plc and Rolls Royce plc offered access to material relevant to the TSR2. I am deeply grateful to them for their generous help and assistance without which it would have been impossible to write the present book. This sup­port has come in many forms over a number of years, and has gone far beyond the routine. Accordingly, I thank both organizations for their systematic support and assistance while noting that what I have written is my own responsibility, and does not necessarily reflect the views of either company.

It is also my particular pleasure to thank the Brooklands Museum at Weybridge, Surrey, British Aerospace North West Heritage Group at Warton, Lancashire, and the Rolls Royce Heritage Trust at Filton, Avon. These are organizations, largely staffed by volunteers, that are responsible for collecting and collating the historical records of the two companies. Their work is indispensable to any student of the his­tory of aviation in the United Kingdom and has been crucial in many ways to the present study. I am deeply grateful to them and in par­ticular to the many individuals who, in serving the historical record in this way, have also generously facilitated the study and helped to ease my way at every turn.

I would also like to thank the numerous employees of British Aero­space and Rolls Royce plc and their predecessor companies, and a number of related companies with whom I corresponded. In many cases these people also agreed to be interviewed, and I am particu­larly grateful to them for generously giving up their time to delve into a project that left distressing memories for many. The same is also true for the politicians, civil servants, and Royal Air Force officers who also unsparingly gave of their time. Since some of them prefer to re­main anonymous, I will not here mention any of these kind people by name. In many cases, however, they offered crucial insights into the TSR2 project, the character of military procurement, the nature of de­fense thinking, and the management of large technological projects.

I am most grateful to the Nuffield Foundation, Keele University, and the Ecole Nationale Superieure des Mines de Paris for financial, material, and practical support for the research. The Nuffield Foun­dation generously offered grant aid to support the original research.

Keele University kindly offered sabbatical and other research leave that made it possible to undertake a sustained period of writing. The Ecole Nationale Superieure des Mines de Paris, and in particular the Centre de Sociologie, offered material support and encouragement throughout. And the Sociology Program of the Research School of Social Sciences at the Australian National University offered fellow­ship support that provided the blessed respite from the usual com­mitments that enabled me to complete the manuscript. The research and this book would most certainly not have been completed without the assistance of these four institutions.

I am very grateful to participants in a number of seminars where I was invited to present earlier versions of parts of this text. These seminars took place at Wetenschaps en Technologiedynamica of the Universiteit van Amsterdam, the Netherlands, CRICT at Brunel Uni­versity, UK, the Department of Social Anthropology at the Univer­sity of Cambridge, UK, the Department of Sociology at Copenhagen University, Denmark, le Centre de Sociologie de l’Innovation at the Ecole Nationale Superieure des Mines de Paris, France, the Centre for Social Theory and Technology at Keele University, UK, the Depart­ment of Sociology at Lancaster University, UK, Tema T at Linkoping University, Sweden, the Department of History and Philosophy of Sci­ence at Melbourne University, Australia, and the Area de Innovacao Tecnologica Organizacao Industrial (ITOI), Programa de Engenharia de Producao, COPPE, of the Federal University of Rio de Janeiro, Bra­sil. The encouragement, support, and critical comments offered at these seminars have been vital to the process of thinking through the arguments that I make here—though I remain conscious of the fact that I have not succeeded in responding to many of the important points raised.

I am deeply grateful to many friends and scholars who have helped, in some cases unknowingly, but more often in the course of exten­sive and generous discussion, to create the intellectual and political space that has led to this book. I would like in particular to mention Madeleine Akrich; Malcolm Ashmore; RuthBenschop; OlafBoettger; Brita Brenna; Michel Callon; Claudia Castaneda; Bob Cooper; Anni Dugdale; Mark Elam; Martin Gibbs; Donna Haraway; Antoine Hen – nion; Kevin Hetherington; Karin Knorr-Cetina; Bruno Latour; Nick viii Acknowledgments Lee; Celia Lury; Mike Lynch; Ivan da Costa Marques; Maureen Mc-

To all of these friends and colleagues I am deeply grateful in more ways than can be told. Many of them have been close intellectual friends for many years—and without them the book would never have been written. I would, however, particularly like to mention two people in this list. I am profoundly grateful first to Michel Callon for his many years of acute intellectual friendship, encouragement, and support, and for his conviction that the book is about distribution; and second, to Annemarie Mol for her strong intellectual friendship, the collaborative work that has gone into earlier versions of this book, and her conviction that knowing maybe performed as partially connected ontology. I thank them both.

As I write these lines I realize that all these friends share a com­mon indifference to the bounds of disciplinary knowledge and a will­ingness to take inter – or nondisciplinary intellectual risks. Such risks seem at least as great in the current climate of unremitting academic audit as they ever have in the past, and I am all the more grateful to them for resisting regional restrictions to the character of intellectual inquiry.

Finally I would like to thank Sheila Halsall, Duncan Law, and An­gus Law who have lived with and contributed to this book in one form or another for more than ten years.

A version of chapter 6 has been published in Configurations, vol. 8, no. 1 (winter 2000). I am grateful to the publisher for allowing it to be included in this volume.

A plateau is always in the middle, not at the beginning or the end. A rhizome 1

is made of plateaus.—Gilles Deleuze and Felix Guattari, A Thousand Plateaus:

Подпись:Capitalism and Schizophrenia

No doubt Deleuze and Guattari have got the right idea. Matters grow from the middle, and from many places. But one also has to start somewhere.

With the aircraft? This is a book aboutspecific episodes in a British attempt to build a military aircraft, a tactical strike and reconnais­sance warplane, called the TSR2. The project to build this aircraft started in the 1950s and ended in 1965 when it was canceled by a newly elected Labour government. In one way or another, all the stories in this book have to do with the TSR2.

But the aircraft is not the only possible place to start. For though all the stories in this book are indeed about the TSR2, the book is really about something much more general. It is about modernism and its child, postmodernism — and about how we might think past the limits that these set to our ways of thinking. For the book is about a world, the contemporary Euro-American world, in which many have lost their faith in big theories or ‘‘grand narratives,” as Jean-Frangois Lyotard calls them (1984b). And, at least to some extent, it is about a world in which many have also lost confidence in the grand projects and plans that tend to go with those grand narratives. Nuclear power, medical practices, food safety, the environment, everywhere, or so the story runs, experts are doubted, and people are skeptical of the claims made by authorities. Including academic authorities.

Of course there are various ways of responding to this. One can wave aside the skepticism of postmodernism and insist that experts— including academic experts—still know best: that it is, indeed, pos­sible to tell grand narratives. One can, in short, remain a modern­ist. Alternatively, one can insist that expert knowledges are limited in scope, but then go on to say that it is still possible to tell consis­tent stories so long as one understands that these have only a lim­ited validity and that they will in due course require revision. No doubt this is the dominant response in many of the social sciences, for instance underpinning the theory of reflexive modernity.1 It is a response that says warrantable knowledge is still possible so long as

it is suitably set about with health warnings and it is not used after its sell-by date.

But there is another possibility that I want to explore in this book. This is to take the skepticism of the so-called postmodern condi­tion seriously, which means accepting that ‘‘modernism’’ is flawed even in its more supple versions. It is to accept that modernism never achieved the smoothnesses it sought, that its foundations were illu­sory, and that when it intervened to try to put things right and make a better world it often—as Zygmunt Bauman has so eloquently shown —wreaked havoc.2 But then it recognizes, and this is crucial, that the pluralist diaspora apparently favored by postmodernism raises prob­lems that are just as difficult. Not only is it clear that we don’t live in a pluralist world in which everyone happily does their own thing, but it is also apparent that the broken fragments celebrated in postmod­ernism are just as much a product of modernism as its own stream­lined coherences ever were. Postmodernism is, so to speak, the mir­ror image of modernism—and postmodernism’s response has simply been to break the smoothness and shatter that mirror. The argument, then, is that modernism and postmodernism exist together. They are each other’s creatures. And as they confront one another they tend to press us to make a choice between the homogeneities of centered storytelling on the one hand, and pluralism of fragmentation on the other. This, then, is a second version of what the book is about. It is an attempt to evade that choice.

But to make the argument I need to be more specific. So a third and more concise way of talking about the stories assembled in this book is to say that they are about fractional coherence. Fractional coher­ence, I will say, is about drawing things together without centering them.

Knowing subjects, or so we’ve learned since the 1960s, are not co­herent wholes. Instead they are multiple, assemblages. This has been said about subjects of action, of emotion, and of desire in many ways, and is often, to be sure, a poststructuralist claim. But I argue in this book that the same holds for objects too. An aircraft, yes, is an object. But it also reveals multiplicity—for instance in wing shape, speed, military roles, and political attributes. I am saying, then, that an object such as an aircraft—an “individual” and ‘‘specific’’ aircraft—comes in different versions. It has no single center. It is multiple. And yet these

various versions also interfere with one another and shuffle them­selves together to make a single aircraft. They make what I will call singularities, or singular objects out of their multiplicity.3 In short, they make objects that cohere.

But how do they do this? This is the major question that I tackle in this book. A question that, while speaking to the general issue raised by the so-called postmodern predicament, at the same time much more concisely refuses the pluralism implied by Lyotard’s multiple language games.

How, then, to think about this? I deploy a range of metaphors for thinking about the overlaps that produce singularity out of multi­plicity. Many of these have grown up in the discipline of STS—of sci­ence, technology, and society. Interference, oscillation, Donna Har – away’s notions of ‘‘the established disorder’’ or the cyborg—these terms catch something important about the relations between singu­larity and multiplicity. But let me mention a further possibility here, that of fractionality. In mathematics fractals are lines that occupy more than one dimension but less than two.4 If we take this as a meta­phor without worrying too much about the mathematics, then we may imagine that fractal coherences are coherences that cannot be caught within or reduced to a single dimension. But neither do they exist as coherences in two or three separate and independent dimen­sions. In this way of thinking, a fractionally coherent subject or object is one that balances between plurality and singularity. It is more than one, but less than many.

I want to suggest that Euro-American culture doesn’t really have the language that it needs to imagine possibilities of this kind. Its conditions of possibility more or less preclude the fractional. Indeed this is one of the reasons why the postmodern reaction—though it diagnoses some of the problems of modernism well enough—still finds itself trapped within a version of the modern predicament. For if things don’t cohere together to form a consistent whole, then it is usually assumed that they don’t cohere at all. So in common sense (as well as much academic and political discourse) the options tend to take the form of the binarism mentioned earlier: between, on the one hand, something that is a singularity because it holds together coher­ently; and, on the other, something that is broken and scattered, as in some kind of pluralism in which anything goes.5 Or between order Introduction 3

and its antithesis, chaos. Thus our languages tend to force us to choose between centers or dislocated fragments. Between the poles of‘‘draw­ing things together’’ and ‘‘the decentering of the subject.’’6 Or be­tween single containers, such as ‘‘society,’’ and plural elements, such as ‘‘individuals,’’ that are contained within society. Fractionality, then, is one of the possible metaphors for trying to avoid such dualisms. For trying to wrestle with the idea that objects, subjects, and societies are both singular and multiple, both one and many. Both/and.

This, then, is the hope: that after the dualist contraries of centering and decentering, after the alternates of singularity and multiplicity, we might find ways of imagining fractionality. This, to be sure, is the hope of a number of scholars and is certainly one of the lessons that we learn from parts of poststructuralism.7 But the program, it seems to me, has not yet found good ways of performing itself—and least of all of doing so empirically. This leads to the fourth significance for the stories that I tell in the book. A fourth way of beginning.

This starts with a question: How should we write? How might we write about multiplicity in a way that also produces the effects of sin­gularity? Or about singularity in a way that does not efface the perfor­mances of multiplicity? In this book I do not respond to this question by offering a single recipe or a formula. Instead I choose to proceed less directly and more allegorically. Or, more precisely, I try to make something, to create it rather than simply telling about it. For this book explores complexity, heterogeneity, and interference not simply by talking about them, but also, and maybe more importantly, by try­ing to perform them.

I believe that if we have not managed to attend very well to the frac­tional coherences of multiple objects and subjects, this is not simply because we have not properly faced the facts. It also has to do with how we investigate our subjects and objects and, in particular, with the ways in which we tell about them. It has, in short, to do with the character of social-science writing. Notwithstanding work in several social-science traditions, we are, to use a phrase, insufficiently self­reflexive aboutthe way in which we write.8 And aboutwhatis implied when we write in one way rather than another. So my hypothesis is that we have not yet recognized and allowed the difficult subjectivi­ties that are needed for fractional knowing. In this book I also help to

bring such less direct ways of knowing into being. The book, then, is an intervention, a performance of fractional ways of knowing.

Perhaps it would have been possible to make a grand narrative about decentered and yet coherent objects. I take it that this is one of the features of Andrew Pickering’s work on the ‘‘mangle of practice,’’ a metaphor that otherwise does work which has much in common with what is attempted in this book: an inquiry into ontology, into what is made, rather than what is represented.9 And the thought of working in terms of a single metaphor is attractive because it offers a key to complexity. And such keys, once in place, are easily expressed and applied. Telling directly about what they tell, they are rendered easily transportable. To say it quickly, such is the dream of modernism in its search for foundational (or now postfoundational) grounds, and it is certainly the project of much contemporary social theory, to which the possibilities of allegory are foreign.10 But here I explore a less di­rect alternative by growing different stories alongside one another. Smaller narratives—a lot of smaller keys. Working in this way has a cost: we do indeed lose the possibility of an overall vision. But at the same time we also create something that was not there before: we cre­ate and make visible interferences between the stories. We bring new and unpredictable effects into being, effects which cannot be pre­dicted or foretold from a single location. New forms of subjectivity.

To do this is to alter the character of knowing and writing. It is to render them multiple, decentered, or partially centered, in this place that refuses both modernism and postmodernism. If single ac­counts offering single keys make arborescences—treelike structures with beginnings, middles, and ends where everything important is held together in a centrally coordinated way—then multiple storytell­ing makes rhizomatic networks that spread in every direction. They make elaborations and interactions that hold together, fractionally, like a tissue of fibers.11 This results in texts that are uncentered, texts that are not singular. And yet, if the bet is right, it produces texts that have intersections, that hold together. That cohere.

So what does all this mean in practice? The answer is that the essays in this book tell specific stories about specific events. In doing so, they play upon recurrent themes to do with partiality, fractionality, inter­ference, and collusion, while doing so in a manner that resists the

simplicities of an overall beginning, middle, and end. The book as a whole, then, is not treelike in structure. It is not an arborescence. In­stead it takes the form of a rhizomatic network. It makes overlaps and juxtapositions, and it makes interference effects as a result of making these overlaps. So that is the fourth way of introducing the book. It is about writing fractionally.

But this suggests a fifth way of talking about the stories of the book, which has to do with how texts relate to the world. Perhaps, to be simple, we might speak of two possibilities. First, we may imagine that they tell about and thus represent a version of reality. If we think of writing in this way, then we distinguish between texts on the one hand, and what they represent on the other. The latter become some­thing separate, out there, prior, removed. This means that we may stand outside and describe the world, and that when we do so we do not get our hands dirty. We are not in the world.

The alternative is to imagine, reflexively, that telling stories about the world also helps to perform that world. This means that in a (writ­ing) performance reality is staged. And such a staging ensures that, everything else being equal, what is being performed is thereby ren­dered more obdurate, more solid, more real than it might otherwise have been. It becomes an element of the present that may be carried into the future.

So what do we perform when we write? There are various by now familiar possibilities. We may perform the world as a treelike struc­ture: such is the desire of modernism as it seeks to perform its cen­tered consistency into being. We may make fragments, which is, to be sure, the postmodern response. Or we may enact it rhizomatically, which is the allegorical or poststructural alternative that I am recom­mending.

In this alternative approach, no matter how stories are told about this aircraft, the TSR2, they do not simply describe something that happened once upon a time. They are rather, or also, away of helping to perform the aircraft. The stories participate in the aircraft. They add to the crowd of forms in which it was already among us, inter­fering with and diffracting earlier versions and thereby altering these forms. Perhaps slightly and locally. Perhaps unpredictably. But never­theless altering them, and making a difference.

So the performativity of writing is a fifth way of introducing the

book, of describing the significance of its stories. But this in turn sug­gests a sixth possibility: that the book is about what it is to criticize, analytically and politically. Its fractional object is, as I have noted, a military aircraft. Why this should have been so is something that I explore in chapter 3. As is obvious, there is much to worry about in military aviation. Had the TSR2 ever been used in its nuclear role, the world would have stumbled into Armageddon. And, leaving aside the horrors of destruction, in the stories that follow we’ll come across ways in which the TSR2, even if it never killed, indeed performed social distributions—for instance those of gender or ethnicity.12 So yes, there is much to worry about here. But there is a problem if we start to criticize from what is supposed to be the outside because doing so ignores the performative character of storytelling that I have just been describing. In particular it ignores the fact that we are all mixed up in what we are describing. That, indeed, in one way or another we are helping to bring it into being. The fact that we are col­luding with what we are describing, colluding to enact it into being.

The conclusion is that in a fractional and reflexive world the luxury of standing outside, criticizing, and correcting is no longer available.

Partly inside, partly outside, we are at least partially connected with our objects of study And if we seek to criticize then it also becomes important to reflect on the character of that involvement. We need to ask whether, and if so how, we share in what we do not like with those whom we do not like. And whether, and if so how, they share some of our own most valued ways of being.

This should not be misunderstood as a plea for political quietism.

Indeed, quite to the contrary. Thus if our writings perform reality, then they also alter it. Every time we act or tell, we also, at least puta­tively, make a difference. We always act politically. The only question is how do we do it?

This book interferes in a variety of ways, but in particular, or so I hope, it interferes with what we might think of as ‘‘project-ness.’’

This is the idea (which is also a performance) that many technologies and other social arrangements are properly narrated and organized as ‘‘projects,’’ ‘‘programs,’’ ‘‘operations’’ or other closely related terms such as “organization,” ‘‘system,’’ ‘‘network,’’ or even the ‘‘reflexive person.’’ These are objects that are somewhat linear, chronologically chained, and more or less centrally and teleologically ordered, and Introduction 7

that are also shaped in one way or another by their circumstances. Think of the TSR2 project. Or the Manhattan Project. Or the mission statements of organizations. Or indeed ‘‘the modern project.’’ Think of large technical systems, or actor-networks. This kind of telling and performing is a standard narrative trope in late modernity. And it is, of course, performative of that modernity, tending as it is told and en­acted to order social relations in an image of projectness. It is one of the aims of this book to interfere with this trope, to erode the assump – tions performed in projectness, or at least to explore what is involved in their enactment. Thus, the sixth argument of the book in effect sug­gests to social scientists that, insofar as they frame what they tell in the form of stories about projects, they too are colluding in reproduc­ing the conditions of projectness as an appropriate narrative form. No doubt this is not all bad. There are moments for this collusion. But if the arguments I am making carry any weight, then that performance tends to efface not only other possibilities but also the fractional con­ditions of the performance of singularity. And, to be sure, set limits to the conditions of possibility.

So there are at least six possible introductions, six ways of telling what the book is about: it is about an aircraft; it is about refusing the space provided by the division between modernism and postmod­ernism; it is about fractional coherence; it is about the reflexive forms of academic subjectivities needed to apprehend the fractional; it is about the performativity of writing; and it is about the collusions that necessarily follow from that performativity. Such are the themes that recur and interfere with one another throughout the book.

Each of the eight chapters that form the body of this book tells its own story and mobilizes its own resources, drawing variously on cultural studies, technoscience studies, feminist theory, philosophy, sociology, cultural anthropology, art theory and history, and semi­otics.

Chapter 2 concerns the problem of multiplicity. It uses a version of semiotics to analyze how an aircraft sales brochure generates first a range of object positions and then coordinates them into a single aircraft. This analysis implies that coherent and single objects are effects or products. It also implies a shift from epistemology to on­tology. This is because inconsistency between different performances

reflects failing coordination between different object positions rather than differences between external perspectives on the same object.

These, then, are two ofthe implications ifwe start to imagine thatnar – ratives are not about self-evidently singular objects but rather have to do with the enactment of fractional relations.

Chapter 3 deals with subjectivity, interpellation, and collusion. It describes how I was multiply interpellated by the TSR2, which im­plies that there is no such thing as a centered subject: like objects, subjects of knowledge are multiple or fractionally coherent. It also suggests that the interferences between these different subject posi­tions are a valuable source of data. This means that if it is properly used, ‘‘the personal’’ is not confessional but analytical in character.

It also, however, means that when subjects are interpellated by ob­jects, they are liable to find themselves colluding in the performance of certain narrative forms. Such was certainly so in the case of the TSR2.

Chapter 4 is about bias in favor of narrative continuity, and the ways in which discontinuities are effaced or deferred. In this chap­ter I identify three versions of narrative continuity: the chronology of genealogy and descent; the synchronicity of systematic connec­tion; and depth hermeneutics, for instance in the form of background factors such as social interests that then shape more superficial phe­nomena. Despite their differences (and these, of course, have been rehearsed in extenso in social theory), each version performs a bias in favor of continuity and connection, while discontinuities are de­ferred into slippages between the different narrative forms and so tend to be effaced. This analysis implies that the difference between insider and outsider cannot be sustained: social scientists and partici­pants alike tell their stories in terms of these narrative possibilities.

They collaborate to perform projectness and its conditions of possi­bility, which include a homogeneous space-time box with its own set of coordinates in the form of chronology and scale.

Chapter 5 concerns oscillation between singular presence and mul­tiple absence. It considers an aerodynamic formalism that seeks to draw things together in an explicit and homogeneous manner. This formalism operates by simplifying and excluding almost everything —including other realities that are represented in algebraic form but cannot possibly appear on a sheet of paper. The formalism is thus Introduction 9

10 Introduction

oscillatory: it necessarily makes absent that which it also seeks to make present. The paradox is that presence and coherence rest on their converse, that which cannot be made present and coherent. This means that absence and presence cannot be dissociated. Again, then, the underlying theme of the chapter is that objects are not singular, indeed not self-identical. That in their heterogeneity they are instead fractional and can only be apprehended fractionally.

Chapter 6 is also about oscillation, this time oscillation first be­tween text and pictures and second within the pictures themselves. The text of the brochure discussed in chapter 2 creates an aircraft that is practical, technically efficacious, and militarily invulnerable. The illustrations extend the performance of military invulnerability but also stress the nonpractical fact that to fly this aircraft is thrilling for a certain kind of heroic male subject. There are other genderings at work as well within the pictures. Though the aircraft itself is some­times performed as a potent male, there are moments when it is made female in a version of the patriarchal fear of the power of woman per­formed in the oscillation between Madonna and whore. Thus the aes­thetics of the illustrations (themselves noncoherent) interfere with the text in ways that are discursively illegitimate in order to perform a singular and obdurate aircraft that is strong and deadly.

Chapter 7 is about decision making. It explores the assumptions about decision making in descriptions about the decision to cancel the TSR2. These include distinguishing between reality and fantasy; effacing the microphysics of power; performing certain places and times as discretionary; distinguishing between that which is impor­tant and that which is a mere ‘‘detail’’; and (in a further example of the oscillation between singularity and multiplicity) the erasure of differ­ences between different decisions in a framing assumption that the decision taken was indeed one rather than many. This assumption of singularity thus makes it possible for different individual decisions to be made—but, I argue, it is necessary for different decisions to be made if a single decision is to be achieved. These, then, are narrative collusions to do with decision making not unlike those entailed in studying ‘‘projects.’’ Again there is oscillation.

Chapter 8 returns to narrative performativity and collusion. It offers several accounts of the TSR2 project that reveal substantial overlaps. In particular, it suggests that the accounts are arborescent in form.

Thus the stories all join in the performance of a single TSR2 and its projectness—and the work of building the kind of homogeneous space-time box described in chapter 4. This analysis suggests, once again, that that the distinction between insider and outsider doesn’t really work; that all accounts are performative (there is a discussion of Austin’s performatives and constatives); and that all collude in the reproduction of the conditions of possibility, which include a singular world and a singular object in which the oscillation with multiplicity is effaced. The hands of the storyteller are never clean.

Chapter 9 considers what comes after centering—for, given the gravitational pull of centered storytelling within the narrative tradi­tions of modernism, escaping from singularity is difficult. Indeed, to talk of ‘‘escape’’ is not the right metaphor because it implies a post­modern fragmentation with the binarisms from which we need to es­cape. In this chapter I first consider the metaphor of the pinboard, the relationship between narratives or other performative depictions juxtaposed on a notice board. I suggest that this metaphor may help us to handle the performative character of our own ways of know­ing in a manner that does not conceal their multiplicity. I then re­turn to the question of the political. The question is, does an insis­tence on fractionality rather than the singularity of social structure imply political quietism? I argue that this is far from the case. Even leaving aside the often-collusive performativity of singular narrative, I suggest that the great social distributions familiar to sociologists and political commentators are all the more obdurate precisely because they are not singular but rather fractional in character. There is no ‘‘weak link’’ in an otherwise coherent structure. Rather there are par­tial and supple connections between distributions that help to secure dominance and reproduce the established disorder.

All of which—and this is the concluding thought—also demand fractional ways of knowing; skepticism about viewpoints that try to perform themselves as simply centered; and an ability to live and know in tension. This is one version of what a rigorous and politically interventionary social science that seeks to avoid both modernism and postmodernism might look like.

Подпись:It was a sales brochure. About sixty pages long, it was published in 1962 by the British Aircraft Corporation. And it was trying to sell an aircraft, the TSR2, to its readers. But what was the TSR2? And who were the readers of the brochure?

Подпись: CMThere are historical responses to both these questions. TSR2 was a tactical strike and reconnaissance warplane being designed and built by the major UK aerospace manufacturer, the British Aircraft Corpo­ration. And the brochure was intended for an elite readership: senior air force officers in the UK or in certain ‘‘friendly’’ countries, most notably Australia; senior civil servants, again in these selected coun­tries; and no doubt a number of well-placed politicians. For the bro­chure was part of an effort to sell the aircraft, both in Britain but more particularly (since the Royal Air Force was already committed to its purchase) to possible overseas buyers.

Those, then, are brief versions of the historical answers. I offer them at the outset because I do not want to be accused of playing games, of withholding context, or of denying the obvious. But the direction in which I wish to move is different. For reasons that will become ap­parent I do not want to frame what I write in terms of the conventions of narrative history. Though this strategy, of course, brings its costs, I want instead to create a naive reader—a naive reader who knows nothing about the TSR2 or the potential readers of the brochure. And I want to use this fiction in order to learn something about how the bro­chure works. So the thought experiment is this: that we read excerpts from the brochure without making too many assumptions about its character, about what it is telling us, or about its likely readers. Some­thing that is not possible if we arrive with the competences and the concerns of the historian.

So what happens if we do this?

Interpellation

So semiotics is the study of relations, including the relational forma­tion of the distribution between the knowing subject and the object that is known. Or, if you prefer the language, between the constitution of the personal, and the knowledges that we have of the world. Michel Foucault was there, a semiotician, but so too was Louis Althusser. And now I want to borrow a term from Althusser: the term interpel­lation.17 Althusser tells a story about ideological state apparatuses.18 Talking of ideology, he says that there are moments of recognition, moments when we recognize ourselves because we have been ad­dressed, called out to, in a particular way. At those moments we be­come, as he puts it, subjects because we are subjected to an authority, a Subject with a capital S. We are located, in relation to that Subject, as biddable small s subjects precisely because we recognize ourselves and (this is crucial) because we have no choice. We are turned into biddable subjects because it becomes instantly obvious to us that we are that way and that we know that way.

Althusser links this relational semiotics with ideology and its oper­ation through ideological state apparatuses. And, though I want to talk about interpellation, I will have to abandon much of Althusser’s project. For instance, his play between Subject and subject: the idea that we are turned into little knowing subjects because we are in­terpellated by, and mirror, a great Subject. This rests upon the idea that in the last instance there is a kind of ideological coherence, some kind of God eye. Well maybe, but if we take seriously the notion of an established disorder, maybe not. At any rate, this isn’t something I want to build into my version of interpellation. I also want to avoid the idea that there are real relations of production that can be dis­tinguished from ideology, that there are, indeed, firm foundations. This, another version of the God eye, makes me uneasy too because, to say it briefly, it’s another division that separates appearances too much from reality, the performance of storytelling from what it tells about. To say this is not to say that we will necessarily avoid resusci­tating something of this kind that does work. But even so, in a non­foundational world, Althusser’s particular version of the distinction between truth and ideology too will have to go.

But I still want to talk of interpellation because it involves two com­mitments. First, it is committed to embodiment. Perhaps Althusser doesn’t go into this as deeply as Foucault, but even so, it is crucial. For (or so it seems) his sense of interpellation draws from and per­forms itself through the body of the ex-Catholic. And the ex-Catholic (is there such a thing as an ex-Catholic?) knows that he came to be­lieve because he first kneeled and prayed, because he participated in ritual. He also knows that all this happened long before he had any sense of faith, explicit or otherwise. Thus embodiment preceded subjectivity, subjugation to the Subject. We are, says Althusser, inter­pellated as knowing subjects precisely because we are embodiments, embodiments of relations and gestures.

Second, I want to hang on to Althusser’s insistence on obviousness. For me this is the fulcrum of interpellation: the subject instantly rec­ognizes itself when it is addressed. Note that: the subject instantly recognizes itself and is constituted as a knowing subject when it is spoken to. Indeed (and he is equally insistent on this) the constitution of the subject precedes the words spoken, the fact of being addressed. So interpellation has nothing to do with ‘‘deciding.’’ All the apparatus of ‘‘rational decision making’’ (assuming we believe in the existence of such a beast in the first place) is bypassed. Instead there is instant recognition and location.

Perhaps Althusser was thinking of words, words and bodies. Per­haps he was imagining the words of the priest, the schoolteacher, the politician, or the bourgeois political economist, the effect of all these words on the body of the subject. But there is no reason to restrict in­terpellation to words. Indeed, the emphasis on embodiment suggests that words are at best only the beginning.

Interpellated

Now I want to narrate a story that joins the personal to that which is not ephemeral, the subject of study with the object of study. This is be­cause I don’t think that the personal is ‘‘personal’’ when it is put in this way. But we’ve needed Alpers, Elias, Foucault, and finally Althusser to reach the point where it is possible to theorize the personal in a way that resists its designation in those terms.

Third Story

The P.17A brochure continues. In the paragraph immediately after the formalism, we read the following: ‘‘By comparing several aircraft, of known characteristics, which have been flown in low altitude tur­bulence, it is possible to decide a maximum value for this parameter which will ensure a comfortable flight’’ (English Electric/Short Bros. 1958, 2.1.9). ‘‘This parameter’’ is G. Gust response again.

Naive Readings

Exhibit 2.1 is from page twenty-five of the brochure. As is obvious, this is a drawing, the drawing of an aircraft. Then the question arises immediately: how naive do we want to make the reader? If we insist on a radical version of naivete then we need to say that there is noth­ing about the picture that links it with the TSR2. For yes, it is a picture of an aircraft. But there is no caption to say that this aircraft is the TSR2.

EXHIBIT 2.1 Perspectival Sketch of Aircraft (British Aircraft Corporation 1962, 25;

Naive Readings© Brooklands Museum)

EXHIBIT 2.2 ”The T. S.R.2 weapons system is capable of a wide range of recon­naissance and nuclear and high explosive strike roles in all weathers and with a minimum of ground support facilities.” (British Aircraft Corporation 1962, 4)

EXHIBIT 2.3 ”In T. S.R.2, high grade reconnaissance is allied to very accurate navi­gation and this suggests the application of the aircraft to survey duties. In many areas the navigation accuracy of better than 0.3% of distance travelled is a signifi­cant improvement on the geodetic accuracy of existing maps. This degree of pre­cision enables new maps to be made or old ones to be corrected with a minimum of accurately surveyed reference points.” (British Aircraft Corporation 1962, 17)

Exhibit 2.2 appears much earlier in the brochure—indeed on the first full page of text. Here we don’t learn anything about an aircraft. Instead, we learn that the TSR2 is a weapons system. We also learn that this weapons system fulfills a range of roles, and that it does so in ways that are independent of the effects of weather and elaborate ground-support facilities. But is it an aircraft? Again, to be sure, it de­pends just how naive we want to be. But ifwe were to dig in our heels then we would have to say that we’ve learned that the ‘‘TSR2’’ is a weapons system, but not that it is an aircraft.

Exhibit 2.3 tells us something about TSR2 and navigation. Here the naive reader does indeed learn that TSR2 is an aircraft, but that reader also learns something about the character of this aircraft: that it has

EXHIBIT 2.4 ”In T. S.R.2 the internal and external communications facilities are completely i ntegrated. Two control units provi de for i ntercommunicati on between the crew and for control of the radio equipment installed.” (British Aircraft Cor­poration 1962, 29)

to do with remote sensing and surveying. TSR2, or so it is being sug­gested here, is an aircraft capable of accurate navigation—but also, and perhaps more remarkably, one that is capable of making maps.

How many more versions of naivete do we need? Exhibit 2.4 turns the TSR2 into a communications system. Exhibit 2.5 (though, like the drawing in exhibit 2.1, it does not mention the TSR2 by name), turns it into a fuel system, complete with pipes, tanks, pumps, and engines. And exhibit 2.6 (again we need to enter the caveat about the absence of a name) turns it into a global traveler, moving to and fro between Britain, Australia, and a host of other points around the globe.

Let’s stop the experiment now. We could pile up more exhibits, but we have learned what we need to learn for the moment: a naive reader who does not start out with an idea of what it is, this TSR2, who does not make connections, will learn that it is many and quite different things.1 Let me stress the point: ‘‘the TSR2’’ is not a single
object; neither, whatever the exhibits might suggest, is it many differ­ent parts of a single object. Instead it is many quite different things. It is not one, but many.

This is the problem of difference: we have different objects. Or it is the problem of multiplicity: we have multiple objects. In other words, a reader who insists on being naive is likely to find that he or she is dealing not with a single object but rather with an endless series of different objects, objects that carry the same name—for instance “TSR2’’—but which are quite unlike one another in character.

Of course, we know that it is not really like that. We know—or at least we assume—that the object, the TSR2, is indeed an object. But why is this? Why do we make this jump? And how does it come about? The ability to pose such questions is the reason for avoiding a histo­rian’s sensibility and the justification for being naive. An initial as­sumption of naivete enables us to ask why the reader for whom the brochure was intended would assume that it was, indeed, describing a single object, a single aircraft, rather than a whole flock of differ­ent machines. In other words, an initial assumption of naivete is a methodological position.2

But why be naive? To answer this question I need to talk of strate­gies of coordination. In particular, I will identify a series of mecha­nisms that work to connect and coordinate disparate elements. The

The Problem of Difference

 

Annemarie Mol has written a book about this, about the problem of difference in medicine.3 Think, she says, of lower-limb arteriosclerosis. Or better, think of the practices within which lower-limb arterioscle­rosis is located. Perhaps we may number three of these.

First, there is a phenomenon the doctors call "claudication." Clau­dication is suffered by patients. It is pain in the legs occurring when the patient walks further than a certain distance. This is diagnosed in general practitioners’ surgeries when the patient is interviewed.

Second, there is the phenomenon of an inadequate flow of blood to the legs and the feet. This usually arises initially in outpatient clinics. The investigating physician measures the pressure of the blood flow at the ankle and compares it with the pressure at some other convenient point such as the top of the arm. If the difference is large then there is said to be pressure loss at the ankle. This loss of pressure is taken to be a sign of increased resistance to the flow of the blood.

Third, there is the phenomenon of the thickening of the intima of the blood vessels in the leg. There are various practices for exploring this, but the most important is located in the pathology laboratory, after the amputation of a diseased leg. The pathologist cuts cross sec­tions through the blood vessels of the leg to detect whether, and if so to what extent, there has been a thickening of the intima of the vessel.

What is the relationship between these practices? There is, says Mol, a textbook explanation. It says that arterial disease leads to a thick­ening of the vessel intima. Beyond a certain point this leads in turn to a fall in blood pressure and, again beyond a certain point, this be­gins to interfere with the blood flow in the legs. When this happens,

 

the leg muscles don’t receive enough oxygen during exercise—and the result is claudication, pain, upon walking.

This textbook story is realist in character. It assumes that there is an object—lower-limb arteriosclerosis—out there that manifests itself in various ways. If one looks as what goes on in hospitals and doctors’ surgeries there are moments, indeed, when this story is quite unprob­lematic. Thus a patient may arrive complaining of claudication, and when his blood flow is measured, it turns out to be inadequate. He may then be treated in one way or another. Rarely—and this is only after all possibilities of treatment have been exhausted—there may be need for amputation. If this happens, the amputated limb is sent to the pathology laboratory and the sectioning of the vessels will reveal, if all goes as anticipated, substantial thickening of the vessel intima.

So there are occasions when it is possible to say that there is an object out there, ”lower-limb arteriosclerosis," that manifests itself in a series of different ways. It often turns out, however, that the three medical practices described above come to different conclusions. A patient may be suffering from claudication, but there appears to be no pressure loss at the ankle. Or a patient whose blood vessels seem to be occluded turns out to have no pain on walking. There are end­less case conferences in the hospital dealing with problems such as these. There are also many strategies for explaining these inconsisten­cies away. And, in particular, there are ways of dealing with the press­ing question as to what should be done for a patient who is in pain or whose lifestyle has been restricted.

Annemarie Mol is a philosopher who argues that the three prac­tices generate three different and sometimes very badly coordinated arterioscleroses. In the plural. And this is the problem of difference: practices may and often do generate multiple rather than singular ob­jects.

 

TSR2 brochure, or so I want to suggest, embodies and performs a number of these.

1985. RAF Cosford

It’s like this, isn’t it? This was a moment of interpellation. Knowing subject, known object, the two were recognized together in a single instant. I would study, study the TSR2; the TSR2 would be studied, studied by me. The effect was, as it were, an instant recognition or performance of a set of subject/Subject or subject/object relations coming from—well, coming from somewhere, but deeply buried in its obviousness, somewhere before.

Obviousness? Let’s just remind ourselves of some of its dangers. If we are interpellated, then we are being made or remade as a particular subject position, made to constitute our objects in particular ways. In particular we are being made to constitute our objects in ways that are obvious, recognized and made before we come to see them and think about them. There is another study here. We might think of it as the erotics of interpellation: Why or how it is that we are spoken to and perform the obviousnesses of our objects of study?19 Technoscience studies, military technologies with all their genderings, biomedical this and that, consumer goods, in all of these we are making obvious­nesses of one kind or another. I say that we are making obviousnesses because our narratives are performative. But if this is the case, then the question becomes: Interpellated as we are, what on earth is it that we are performing in our embodiments?

Heterogeneity and Absence/Presence

On the one hand the two excerpts are contiguous. It is reasonable to imagine continuity, co-presence, and more relations of difference — an organization in terms of the narrative relations discussed in chap­ter 2. But as we read on and a moment passes, so the field of presence starts to shift. Before, it was a matter of formalisms, terms that stood in quantifiable relations with one another. Now it is something differ-

When we looked at that formalism we already knew that some­thing was absent. We knew that there was one kind of logic at work, a logic of absence. We also knew that this absence was an engineer – ing/algebraic logic, one of pragmatic simplicity, the business of limit­ing complexity in order to secure ease of manipulation. But there were other kinds of absence too. Indeed in order to make the narrative work, I let slip a clue. For by referring to ‘‘lift slope’’ as ‘‘idle’’ I traded on another absence: the suspicion that the reader would ‘‘know’’ what was meant by such terms as weight or surface area—which, by im­plication, were not idle. This, then, was the performance of another logic of absence.

The second excerpt takes us in another direction. For new kinds of relations are being performed, relations that no longer have to do with formalisms but rather with the flying of aircraft. I will delve into this shortly. But first let’s focus on the changing relations of presence. The second excerpt performs a subtle shift. It ‘‘reminds’’ us what is absent from the formalism. But this is a double effect: it ‘‘reminds’’ us that there is no reference to ‘‘the real world,’’ to what ‘‘actually happens’’ (as opposed to what might happen), but it also inserts that absent ‘‘real world’’ into the formalism, which means that after the second excerpt the real world is, as it were, both present and absent from the formal­ism, and that the formalism has started to acquire extra weight, an extra weight of difference. It has started to acquire this weight in the impossible interference between absence and presence.

This, then, is how I define heterogeneity, heterogeneity in design, and heterogeneity elsewhere. Heterogeneity is an oscillation between absence and presence. How it is that whatever is not there is also there. How that which is there is also not there. Both/and rather than either/or. Or both/and either/or and both/and. Heterogeneity, then, is about the differences that reside in connection and disconnection. Or, more precisely, it is about the ambivalent distributions entailed in dis/connection. Which means that simplicity is not simply about absence but it is also about presence. Hence the term heterogeneity/ simplicity.

Now we can ask: Are there other forms of absence/presence? Are there other heterogeneities?

Fourth Story

If we stay with the aircrew a little longer and search through the pile of documents we find this:

The state of the pilots is variously described as ‘‘tired,’’ ‘‘bathed in sweat,’’ ‘‘weakness in limbs,’’ ‘‘headache.’’ The main factors causing fatigue appear to be several. There are oscillations in the higher frequencies to which various portions of the human anatomy respond. . . , moderate impacts which continually jar the pilot and throw him about, and occasional large gusts which frighten him by giving the aircraft a violent movement. In addi­tion the pilot had the strain of carrying on with his job, and the worry whether the aircraft structure would stand up to the treat­ment. (English Electric 1957)

This paragraph is taken from an internal English Electric memo­randum. Observing next that the pilots are ‘‘near the limit of their en­durance,’’ it continues:

The navigator, who has his eyes on his instruments, will be more prone to sickness than the pilot who looks at the horizon.

At the same time he will be trying to extract precise informa­tion from a variety of electronic equipment requiring fine adjust­ments to be made by hand. (English Electric 1957)

Syntax

Let’s start very humbly, even though the point is obvious and may be made very briefly The brochure coordinates different objects, differ­ent TSR2s, in part by means of syntax. Exhibit 2.2 is an example of this: TSR2 is a weapons system, or so we learn; it is capable of recon­naissance roles; it is capable of nuclear roles; it is capable of high – explosive strike roles; it is capable of operating in all weathers; and it is capable of doing so with a minimum of ground support facilities. How then is TSR2 made into a single object, rather than four or five? Of course the answer is by syntax. What might be several aircraft are being grammatically turned into one.4

Large Blocks

Michel Foucault and Louis Althusser have something in common other than their radical politics and their semiotic interest in rela­tions. Both tend to imagine that the logics of discourse, of semiotics, come in very large chunks. Althusser, talking of the multiplicity of and differences between ideological state apparatuses (ISAs), writes: ‘‘If the ISAs ‘function’ massively and predominantly by ideology, what unifies their diversity is precisely this functioning, insofar as the ide­ology by which they function is always in fact unified, despite its diversity and its contradictions, beneath the ruling ideology, which is the ideology of the ‘ruling class’’’ (Althusser 1971, 139). And Fou­cault? ‘‘In the last years of the eighteenth century, European culture outlined a structure that has not yet been unravelled; we are only just beginning to disentangle a few of the threads, which are still so un­known to us that we immediately assume them to be either marvel­lously new or absolutely archaic, whereas for two hundred years (not less, yet not much more) they have constituted the dark but firm web of our experience” (Foucault 1976,199).

‘‘Is always in fact unified.’’ ‘‘The dark but firm web of our experi­ence.” So the metaphors and the theories are different, but they have this much in common. Despite the cracks and the strains, most of the space—the space made by ideology for Althusser and the episteme for 52 Subjects Foucault20—most of the space we have for knowing and being, living

and building is structured by a single set of ontological strategies or distributions. These distributions (this is the crucial point) displace others to the margins, to the places that Foucault, with his exquisite sense of spatiality, sometimes calls the heterotopic.21 They are dis­placed to a few places of resistance. Althusser again: ‘‘I ask the pardon of those teachers who, in dreadful conditions, attempt to turn the few weapons they can find in the history and learning they ‘teach’ against the ideology, the system and the practices in which they are trapped’’ (Althusser 1971,148).

This is okay intellectually if not politically. Perhaps it is really like that. Perhaps, to use Donna Haraway’s very different words, we live in a world dominated by narrative metaphors that perform ‘‘militar­ism, capitalism, colonialism and male supremacy.’’ Perhaps we live in a world in which the narratives that perform one another tend to support one another despite some discordances and thereby produce such obnoxious singularities. Perhaps we live in a world in which the ‘‘personal’’ subject positions into which we are interpellated are, in­deed, more or less consistent, performed as reasonably coherent and well coordinated locations within a single great episteme. Perhaps we live in a world that presses toward singularity rather than multi­plicity, a world that is modern rather than postmodern in character.22 If it is like that, or largely like that, then an inquiry into our interpel­lations as knowing subjects seems necessary, indeed vital. That is, if (like Althusser’s teachers) we can manage ‘‘to turn the few weapons [we] can find. . . against. . . the practices in which [we] are trapped’’ and so make different stories and narratives, narratives that explore the ways in which our constitution as subjects has generated objects and knowledge relations that perform their obviousness under what­ever sign ‘‘science’’ and ‘‘reality’’ now sail.

Perhaps. But I am just a little more optimistic than that because I take it that the established disorders are multiple as well as singu­lar. Notwithstanding the coordinations of the many strategies for co­ordination, the strains toward singularity are counterbalanced by the heterogeneity of multiplicity, and the interferences and overlaps do not necessarily ensure that the fields of ontological force are aligned. I am more optimistic because I take it that the conditions of possibility do not necessarily come in large blocks.23

1985-1989

Between 1985 and 1989 I studied the TSR2.1 sought to develop actor- network theory by adding the TSR2 to the long list of technoscience case studies: bicycles, electric lighting, electric vehicles, electricity power systems, imperialist ships, turbojets, Pasteurizations, aqua­cultures, domestic heating, technology transfers. I was specially con­cerned with the social and the technical. The social, or so I sought to show, was as malleable as the technical. Its shape was not given in the order of things but rather emerged in the course of “heterogeneous engineering.” To show this I told stories to do with the trajectory of the TSR2 project, its rise, its development, and its fall. I also told stories of particular specificities in this trajectory, particular incidents. I was quite pleased with some of these project stories. In the space created for this new sociology of technology they seemed to work reason­ably well.24 But things started to go wrong. This showed itself in a number of ways. In particular, however, I started to become uneasy about my relationship with this aircraft, and especially, with its high – status spokespersons. These were people who were often impressive, thoughtful, successful, and attractive. But as I talked to them, I gradu­ally found that these conversations seemed to be laying a charge on me: I was being constituted as the person who would document this project “definitively” It was, or so some of them said quite explicitly, the right time to document the project. Far removed from those sad days in 1965 when the aircraft was canceled, people could now look back calmly and reflect upon what had happened. By now mostly in retirement, enough of them were still alive to make the study possible.

And then this. I wanted to write an actor-network story, a narra­tive exploring the malleability of the technical and the social. But my interviewees knew nothing of actor-network theory Instead, they treated any empirical description as an admittedly crucial prelude to the more important task of making balanced judgments—and two such judgments in particular. First, whether it was indeed right to have canceled the TSR2. And second, and more generally, what might be learned from this sorry story that could be applied to other military aircraft projects.

I had written most of a book on the TSR2 project. But toward the end of 1989 I put that manuscript in a box, put the box on a shelf, and

went to work on a quite different project. And that manuscript is still in its box.

Heterogeneity/Materiality

Let’s talk first of absence—for here we have a second form of absence.

This isn’t a matter of simplicity, or if it is, then it is a new form of simplicity. For this is material absence. Removed from the flat space occupied by the formalism, we find ourselves in the sweating world of the aircrew. We discover pilots who flew their creaking aircraft too low, who worried about whether the wings would break off, who were thrown about their cockpits, and who climbed shaking from their air­craft at the end of these flights.

If we are imaginative enough then perhaps we can smell the fear, feel the sweat on the bodies, taste the vomit. For this is another set of presences, another set of relations, another syntax. It is another set of differences—different presences that are absent from the space of

algebra. Heterogeneities 97

Heterogeneity/Materiality

Sweat

 

Fear

 

Gust

Response

 

Pilots

 

Nausea

The corporeal or, if we include the aircraft, the corporeal with the technological—these are absent from the space of the page, from the formalism about G, gust response. This is the absence of materiality. For, in the way they write the P.17A brochure, there is no room for vomit. It does not fit. There is no room for sweat in formalisms. In the documents that are sent to the government ministries, there isn’t enough space for the test aircraft they used, such as the Meteor air­craft. So they are removed, and not simply because there isn’t enough room, but also because they are materials that do not perform them­selves in the differences of the page, within a logic performed in alge­braic difference.

And yet, these are absences that are also present. For G is there on the page. Gust response is fixed. It is fixed not by the other parame­ters that occur in the formalism (though these are fixed in their re­lations with one another). Rather, it is fixed in a set of relations, re­lations of absence/presence, to do with the suffering of the aircrew. ‘‘By comparing several aircraft, of known characteristics, which have been flown in low altitude turbulence,” (I quote the sentence again) ‘‘it is possible to decide a maximum value for this parameter which will ensure a comfortable flight.’’ A parameter to do with comfort, the comfort of a particular aircrew. Comfort that will allow them to per­form the task of piloting the aircraft efficiently, properly.

Absence/presence, the absence of materiality that is also a pres­ence—no doubt this is what those who write actor-network studies intend when they talk of ‘‘translation’’ and ‘‘chains of translation.’’ (See, e. g., Latour 1993.) And this is a second oscillation in the dis­tributions of heterogeneity: the absent presence of materiality, the Otherness of materials that don’t fit in. But do.

Physical Structure

The second strategy is almost equally humble. This is the physical structure, not of the aircraft, but of the brochure. As I’ve said, the latter is sixty-odd pages long. More important, these pages are num­bered and bound, together with a cover, a title page, and a table of contents. I shall have more to say about the table of contents shortly. For the moment let me just observe that the cover (exhibit 2.7) maybe understood as a mechanism that glosses whatever it is that will fol­low within the pages of the brochure. Announcing itself in bold type, ‘‘TSR2,’’ and then adding in a smaller cursive typeface, ‘‘Weapons Sys­tem,’’ the cover frames or coordinates the contents of the brochure. Presumptively, then, and as a result of this, everything within the bro – chure—and that includes the above exhibits—will have ‘‘something to do’’ with the TSR2. Physical structure, then, is a second strategy for coordinating disparate objects or object positions.
