Looking over the course of my half century working in the fields of Latin American and US history, I find that from the beginning to the end I have been working in a relatively isolated area of our historical profession.Footnote 1 I have been committed to history as a social science, and in that framework, using mostly comparative and quantitative analysis to study themes related to basic social and economic structures. In this I have been much influenced by the traditional vision of the Annales school of historical research. I have also been totally committed to working within the social sciences, having completed a minor doctoral field in Anthropology at the University of Chicago.
But the profession even in its older days was uneasy with its social science label, a label that it seems to have mostly abandoned in the current era. In the 1960s when I first began to publish, history journal editors were often reluctant to publish work containing tables, though that quickly changed. They also found dual-author articles rather strange: to this day you will find very few such articles in historical journals, although they are common to the other social sciences.
After completing my studies in History and Anthropology at Chicago, working with Eric Wolf and Seth Leacock among others, I continued my training in the social sciences as a junior faculty member, working closely with an extraordinary group of other junior faculty members in the social sciences at Chicago. These included Robert Fogel and Philippe Schmitter, in economics and political science, and through them I read extensively in the social sciences literature and began learning quantitative methodology. This post-doctoral education continued in my early years at Columbia, where I worked with sociologists Donald Treiman and Jonathan Kelley on questions of social mobility.
It was Donald Treiman who introduced me to the more sophisticated applications of statistical analysis. I went through the punch-card and card-sorter phase for my first article on the slave trade and then moved on to the mainframe in the late 1960s, complaining about every new invention or procedure which I had to learn. But despite the fact that I was the only historian working at the computer centers at Chicago and Columbia, I persevered. My greatest triumph over the machines was when I succeeded on my own in mounting and reading a Russian-made tape that Manuel Moreno Fraginals had sent to me from Cuba to be used in our analysis of slave prices.Footnote 2
From all this varied experience I learned that I enjoyed working with people with viewpoints and methodologies different from my own and that they in turn appreciated my own quite different historical vision. This enabled me to begin a long period of joint research and publication with economists, sociologists, and anthropologists, and with many historians as well. Although I have continued working alone like a traditional historian on numerous themes in colonial and modern Latin American history, early on I also worked with other scholars. My first joint article was with a young historian, Marcello Carmagnani, who I met in the mid 1960s when we were both working in the AGI [Archivo General de Indias] in Seville.Footnote 3 Through Robert Fogel I met the economist Stanley Engerman in Chicago in the mid 1970s and began working with him on themes of slavery and the Atlantic slave trade, as well as on the history of prices.Footnote 4
When I moved to Columbia in 1969, I started my first work on Brazil with the economist Nathaniel Leff.Footnote 5 I also began a collaboration with the sociologist Jonathan Kelly on questions of social mobility.Footnote 6 Then, in the 1970s, I began an entirely new field, the study of Spanish and Spanish American royal finance, in collaboration with two historians, the late John Tepaske and Jacques Barbier. My work with John Tepaske resulted in a multivolume publication of royal financial accounts for the major viceroyalties of the New World.Footnote 7 Jacques Barbier and I produced a series of articles on Spanish royal finance.Footnote 8
In the late 1970s and early 1980s I started teaching in Brazil, where I collaborated with the historical demographer Clotilde Pavia on studies of the free-colored in Minas Gerais.Footnote 9 In that same period Iraci Costa de Nero introduced me to the economist Francisco Vidal Luna, with whom I have published five books and numerous articles and with whom I continue to work on new studies on modern Brazil.Footnote 10 Along the way I edited a book with the economist Edmar Bacha and joined forces with David Eltis to help produce the first slave voyages collection, and even produced a book with my former student Ben Vinson.Footnote 11 Despite my intense interest in Latin America, I also found time to do several monographs on the United States, one of which was a joint work with the historian Laird Bergad.Footnote 12
Beyond interacting with scholars from other disciplines and other countries, I have even had the temerity to retrain myself as a Brazilian historian, despite all my years of work in Spanish America. If that was not odd enough, I decided to teach quantitative methodology to historians. This I did for many years at Columbia and Stanford, as well as the Instituto Torcuato Di Tella [Buenos Aires], the Colegio de Mexico, the Universidad Nacional de Chile, the Universidade de São Paulo and the Universidade Federal do Paraná. Thus my career in both research and writing, and teaching, has been an unusual one by the standards of the profession.
I have not suffered for being a relative outsider, but have gotten the usual awards, grants, editorships and teaching positions. Occasionally, I would run into historians who thought my work was ahistorical because I used punch cards and worked with numbers. But these objections were part of the normal debates of the period. Recently, however, I have found the profession less and less accommodating to my type of work, at least here in the United States. It is true that numerous new fields of study have emerged among historians in recent years, many quite original and interesting, and they are worthy of respect for their innovative approaches. But there is a growing lack of tolerance among North American historians for my kind of quantitative and comparative work or studies that do not fit into the new styles, especially in the field of social history where I do most of my own research. What has disturbed me most is my extensive reading of recent theses being produced at leading American universities. Over the past 12 years as editor of the Cambridge University Press Monograph series on Latin America, I have read 30 to 40 of these dissertations from leading centers. Many of them demonstrated little or no sense of how to sample data, confused supposed canonical cases for whole classes of persons or events, and evidenced little awareness of traditional literature or comparative sense. At times, they were written in an impenetrable language.
This inward turning of the profession toward the humanities is occurring just as the other social sciences are making ever deeper commitments to historical research and taking up themes that used to be treated by historians. This in fact is a major shift within the social sciences, which a half century ago were far less interested in historical questions, and when historians were far more willing than now to do serious research in economic, political, social, and even demographic history.
While all fields in the social sciences have become more historically oriented, the biggest change has come in economics. Not only do you have economic historians doing this research, but also mainline economists. Today the call from leading economists in many fields is for a deeper understanding of historical process as a fundamental aspect of economic research. As Thomas Piketty has famously argued, economics without history is not a science.Footnote 13 His arguments have been supported by a diverse group of economists, especially in the recent discussion of the world economic crisis of 2008, which has revived interest once again in the causes of the Great Depression and the impact of historical financial crises in general.Footnote 14
But there also has been important new research by economic historians, and on a host of topics. In my own field of study there is little question that the work of economists has been fundamental in enriching the historical study of African slavery in Latin America. Yet, there have recently appeared studies on slavery and capitalism by US historians that virtually ignore all this accepted research.Footnote 15 This is a rather shocking indication of the growing divide between history and economics, just at a time when other research areas have been deeply enriched by their study of economics. Thus, political scientists, as well as economists, have been much influenced by what has been labeled the New Institutional Economics and involves analysis both of contemporary institutions that affect markets and the historical origin of those institutions. Economists such as North, Sokoloff and Engerman and Acemoglu, Johnson, and Robinson, to mention just a few, have generated enormous international interest in their attempts to discover the factors that created the institutions which later determined the economic and social developments of a given society, and why some societies evolved institutions that promoted wide-scale economic growth and others retained institutions that rewarded only a few at the expense of the many.Footnote 16
Some have argued that initial resource endowments have defined later economic developments, whether they be mines or fertile lands. Others have argued that the determining factors were pre-existent population densities and empires conquered by Europeans, as opposed to sparsely settled regions where Europeans established colonies. Whether it was resource endowments, disease environments, pre-existent social structures, or other initial factors that lent themselves variously to elite exploitation or to more egalitarian outcomes, the ideas are openly debated. But all these influential new institutional economists have argued, following the lead of Douglas North, that these initial factors influenced later social and economic institutions and that these historic institutions in turn help to explain the differences in contemporary economies and societies.
Some of the new institutional economists have carried out a lively and ever more interesting debate about why backward Europe and not Asia ended up dominating the rest of the world after 1500. This so called “divergence” debate has proposed a plethora of hypotheses as to whether it was Europe's concentration of artisans in urban centers, the constant aggressive warfare by the small states of Europe, the European family model, an early commitment to property rights, the availability of new American lands for an exhausted Europe, or a host of other institutions that led to European domination.Footnote 17 Whatever the model, the outpouring of books on this subject has in fact led to some first-class historical research by economists and historians.
But economics is not the only social science where major historical research is being done. Several of the themes central to the New Institutional Economics stress the role of political institutions, and these are also central to recent political science literature. Also, many of the areas currently being examined by political scientists are ones that historians deal with as well. To give just a few examples, the study of the origins and evolution of the modern welfare state, in which I have been involved for several years, has generated a controversial sociological and political science literature that tries to explain how such state institutions were created, where the ideas for them originated, and which classes and groups have supported them. Fortunately, this is one area where historians, political scientists, and sociologists have all continued to do detailed historical studies.Footnote 18
There are other areas of study, however, in which I see few historians working, but which could be of specific interest to Latin American scholars. The debate in political science about the viability of democratic systems, the nature of authoritarian regimes, and the question of transitions between the two, have all generated much discussion in the political science and sociology fields.Footnote 19 In fact, much of this literature goes back to earlier classic studies by sociologists and historians, as well as political scientists. As the sociologist Charles Tilly has suggested, in his study of state formation, “There is no way to create comprehensive, plausible, and verifiable explanations without taking history seriously into account.”Footnote 20 Similarly, historians are uniquely prepared to produce basic studies on historical inequality in ways that other social scientists are not equipped to do. I myself have explored this theme in a limited series of studies, and in our field it continues to be a major theme of debate among Mexican economists and economic historians.Footnote 21 Was inequality less marked in pre-industrial societies, or has society always been as highly unequal as today? What are the trends?
Historians can make use of wills and testaments, voting records based on property qualifications, tax lists, and militia records—all classic sources for such studies—to answer these questions. For example, there is a very lively debate in our field about income distribution in nineteenth-century Mexico.Footnote 22 Thus, we historians can actively engage in one of the most debated current issues in economics today, the question of trends in inequality. What is most useful to historians in the current political science literature is scholars' efforts to generate formal models. The questions they ask and the models proposed often provide an excellent set of themes that historians examining a particular historical case would find of great utility in organizing their own research. Unfortunately, the political scientists sometimes test these models using large cross-national datasets rather than with detailed historical analysis. While historians do not have to wade through these exercises in statistical analysis, they can nonetheless extract from them some excellent questions and models that can guide their own detailed research and nourish significantly these ongoing debates among the political scientists.
It is surprising to me that when I first began to write and do research in the 1960s and 1970s it was historians who were major participants in some of the research fields now dominated by political scientists, for example, the study of legislatures and elections. But recently, these fields have been neglected by historians and are now worked more assiduously by others. There are also fields that historians entered in a major way in combination with other social scientists, only to abandon those interests more recently. An example of this is the early work in demographic history, which saw a very active participation of both historians and demographers, but has now seen a falling away of historians, with fewer of them committed to this field.Footnote 23
Yet, some of the biggest recent debates are unresolved and still awaiting more systematic historical research. Thus, for example, the cause of the mortality revolution, one of the great historical changes in human history, is still a much debated issue. Was it modern medicine, sanitation and public health policies, or simply better nutrition that led to the extraordinary decline in mortality during the late nineteenth and early twentieth century?Footnote 24 That historians can become active participants in these debates is shown by the recent growth of the subfield of anthropometric historical studies, that is, the study of the heights of populations as an indicator of health standards. Taking the lead of economists, who first explored this notion, historians especially in Latin America, are producing an impressive literature on the subject.Footnote 25
This major takeover of whole fields of historical studies by the other social sciences has resulted in both good historical research and a spate of poorly conceived and executed “historical studies.” There have been many path-dependency studies done by economists who have demonstrated a critical lack of serious historical research, just as there have been studies by political scientists who use large datasets to make claims with little historical depth that are based on questionable variables as proxies for basic historical indices. This in no way invalidates the need to work with these scholars—or to use their models and hypotheses to test them through detailed historical research. We have the tools and abilities that the other social sciences lack, and their need for our work is fundamental.
Jared Diamond and other social scientists have even proposed that history is the prime laboratory for social science research, since it allows for “natural experiments” that are otherwise unavailable to most of the social sciences. They often cite to the contrasting development of North and South Korea after World War II as an excellent case for such a quasi-natural experiment, but they have also found value in studies of the impact of the slave trades on various societies of Africa, the varying institutional changes in European countries conquered by the French Revolutionary armies, and in British colonial direct and indirect rule in India.Footnote 26 There are even important historical issues identified in some of the new biological sciences, above all genetics, that provide important tools to answer basic historical questions about the preconquest history of the Americas as well as post-contact migrations.Footnote 27 We historians could easily participate actively in these discussions, but I find few of my colleagues willing to read this work, or engage these issues.
What also impresses me is that this falling away from the social sciences is very much a North American and, to a lesser extent, a Northern European characteristic. From my work in Latin America I have a sense that historians in those countries and in Southern Europe—especially in France, Iberia, and Italy—are far more open to the social sciences and have been more engaged with them from the beginning than their counterparts in the United States. In these countries, as in the United States, new cultural studies have emerged, but they are not as dominant as they are here. Rather, they are just one of many related approaches, thanks in part to the continuation of the older Marxist tradition and to the ongoing influence of the Annales school. It may be for this reason among US historians my writings on Latin America have greater resonance than my writings on the United States. In this country social scientists have responded well to my studies on population, for example, but few US historians find them interesting. At the same time I have recently found an unusual niche for my recent work in Brazilian social history, where I have been marked as a historical sociologist. Since sociology in Brazil is far less quantitatively committed than it is here in the United States, I have been asked to write articles on contemporary social change from a broad historical perspective for several major collections of general or modern Brazilian history, a subject that is usually the area of competence of sociologists.Footnote 28
However much effort it takes, we should not turn our backs on the social sciences and create our own stunted versions of economic or social history, as has recently been argued by several historians.Footnote 29 As Naomi Lamoreaux has suggested, there is a middle ground in which both groups can work fruitfully and enrich both fields. The questions these economists and other social scientists ask are fundamental. There is no reason why historians cannot deal with these issues and provide valuable insights into these questions, or even directly challenge these causal models.Footnote 30 Whether they do history well or poorly, these social scientists have offered interesting and important hypothesis that can be fruitfully used and tested by historians.
What I can say from all this reading and personal experience is that the social sciences, which when I began my career often tended to be ahistorical, have now overwhelmingly abandoned this hostility and moved toward a fuller appreciation of the importance of historical understanding for answering some of the most basic questions they treat. It is my hope that historians will read this literature and respond to it creatively. My plea, then, is not for the profession to abandon its current concerns with agency or identity, for example, but to also provide for and tolerate alternative approaches. I hope that in the future more of us can rejoin the social sciences and participate in these important debates. Otherwise our work will be done badly by others, and we in turn will find ourselves less and less relevant and ever more isolated from the major issues facing the modern world.
