In memory of William Baumol

Princeton University Press is saddened to learn of the passing of the great American economist, William Baumol. Baumol was the Harold Price Professor of Entrepreneurship and Academic Director of the Berkley Center for Entrepreneurship and Innovation in the Stern School of Business at New York University; senior economist and professor emeritus at Princeton University, and a prolific author. He will be remembered for his numerous contributions to the study of innovation and economic growth, including a famous theory known as Baumol’s cost disease, recalled here.

Everyone’s favorite genius takes the spotlight

Along with Einstein fans everywhere, we’re fairly excited to binge-watch National Geographic’s upcoming series, “Genius”, premiering Tuesday, April 25. The first episode shows a young Einstein (Johnny Flynn), poring over the nature of time, a concept well covered in our An Einstein Encyclopedia along with most any other topic that could interest an Einstein devotee, from fame, to family, to politics, to myths and misconceptions. In Genius, prepare to see a show-down between a feisty young Einstein and a particularly rigid teacher. Engrossing to watch—and bound to leave viewers wanting more. Not to worry: “Teachers, education and schools attended” are covered in depth in the Encyclopedia, as are “Rivals”.

Episode 2 of Genius promises to show Einstein embarking, after much head-butting, on a love affair with the determined Mileva Maric. Often remembered as the lone, eccentric, Princeton-based thinker, Einstein’s youthful relationship with Maric sometimes comes as a surprise even to Einstein fans. And yet in 1903, a young Albert Einstein married his confidante despite the objections of his parents. Her influence on his most creative years has given rise to much discussion—but theirs was only one of several romantic interests over the course of Einstein’s life that competed with his passion for physics. Einstein’s love life has been the subject of intense speculation over the years, but don’t believe everything you hear: “Romantic Interests: Actual, Probable, and Possible”, all included in the Encyclopedia, won’t leave you guessing.

Mileva Maric, first wife of Albert Einstein

 An Einstein Encyclopedia is the single most complete guide to Einstein’s life, perfect for browsing and research alike. Written by three leading Einstein scholars who draw on their combined wealth of expertise gained during their work on the Collected Papers of Albert Einstein, this accessible reference features more than one hundred entries and is divided into three parts covering the personal, scientific, and public spheres of Einstein’s life.

With science celebrated far and wide along with Earth Day this past weekend, what better time to get your dose of genius and #ReadUp.

Oscar E. Fernandez on The Calculus of Happiness

FernandezIf you think math has little to do with finding a soulmate or any other “real world” preoccupations, Oscar Fernandez says guess again. According to his new book, The Calculus of Happiness, math offers powerful insights into health, wealth, and love, from choosing the best diet, to finding simple “all weather” investment portfolios with great returns. Using only high-school-level math (precalculus with a dash of calculus), Fernandez guides readers through the surprising results. He recently took the time to answer a few questions about the book and how empowering mathematics can be.

The title is intriguing. Can you tell us what calculus has to do with happiness?

Sure. The title is actually a play on words. While there is a sprinkling of calculus in the book (the vast majority of the math is precalculus-level), the title was more meant to convey the main idea of the book: happiness can be calculated, and therefore optimized.

How do you optimize happiness?

Good question. First you have to quantify happiness. We know from a variety of research that good health, healthy finances, and meaningful social relationships are the top contributors to happiness. So, a simplistic “happiness equation” is: health + wealth + love = happiness. This book then does what any good applied mathematician would do (I’m an applied mathematician): quantify each of the “happiness components” on the left-hand side of the equation (health, wealth, and love), and then use math to extract valuable insights and results, like how to optimize each component.

This process sounds very much like the subtitle, how a mathematical approach to life adds up to health, wealth, and love. But just to be sure, can you elaborate on the subtitle?

That’s exactly right. Often we feel like various aspects of our lives are beyond our control. But in fact, many aspects of our lives, including some of the most important ones (like health, wealth, and love), follow mathematical rules. And by studying the equations that emerge from these rules you can quickly learn how to manipulate those equations in your favor. That’s what I do in the book for health, wealth, and love.

Can you give us some examples/applications?

I can actually give you about 30 of them, roughly the number discussed in the book. But let me focus on my three favorite ones. The first is what I called the “rational food choice” function (Chapter 2). It’s a simple formula: divide 100 calories by the weight (say, in grams) of a particular food. This yields a number whose units are calories per gram, the units of “energy density.” Something remarkable then happens when you plot the energy densities of various foods on a graph: the energy densities of nearly all the healthy foods (like fruits and vegetables) are at most about 2 calories per gram. This simple mathematical insight, therefore, helps you instantly make healthier food choices. And following its advice, as I discuss at length in the book, eventually translates to lower risk for developing heart disease and diabetes, weight loss, and even an increase in your life span! The second example comes from Chapter 3; it’s a formula for calculating how many more years you have to work for before you can retire. Among the formula’s many insights is that, in the simplest case, this magic number depends entirely on the ratio of how much you save each year to how much you spend. And the formula, being a formula, tells you exactly how changing that ratio affects your time until retirement. The last example is based on astronomer Frank Drake’s equation for estimating the number of intelligent civilizations in our galaxy (Chapter 5). It turns out that this alien-searching equation can also be used to estimate the number of possible compatible partners that live near you! That sort of equates a good date with an intelligent alien, and I suppose I can see some similarities (like how rare they are to find).

The examples you’ve mentioned have direct relevance to our lives. Is that a feature of the other examples too?

Absolutely. And it’s more than just relevance—the examples and applications I chose are all meant to highlight how empowering mathematics can be. Indeed, the entire book is designed to empower the reader—via math—with concrete, math-backed and science-backed strategies for improving their health, wealth, and love life. This is a sampling of the broader principle embodied in the subtitle: taking a mathematical approach to life can help you optimize nearly every aspect of your life.

Will I need to know calculus to enjoy the book?

Not at all. Most of the math discussed is precalculus-level. Therefore, I expect that nearly every reader will have studied the math used in the book at some point in their K-12 education. Nonetheless, I guide the reader through the math as each chapter progresses. And once we get to an important equation, you’ll see a little computer icon next to it in the margin. These indicate that there are online interactive demonstrations and calculators I created that go along with the formula. The online calculators make it possible to customize the most important formulas in the book, so even if the math leading up to them gets tough, you can still use the online resources to help you optimize various aspects of health, wealth, and love.

Finally, you mention a few other features of the book in the preface. Can you tell us about some of those?

Sure, I’ll mention two particular important ones. Firstly, at least 1/3 of the book is dedicated to personal finance. I wrote that part of the book to explicitly address the low financial literacy in this country. You’ll find understandable discussions of everything from taxes to investing to retirement (in addition to the various formulas derived that will help you optimize those aspects of your financial life). Finally, I organized the book to follow the sequence of math topics covered in a typical precalculus textbook. So if you’re a precalculus student, or giving this book to someone who is, this book will complement their course well. (I also included the mathematical derivations of the equations presented in the chapter appendixes.) This way the youngest readers among us can read about how empowering and applicable mathematics can be. It’s my hope that this will encourage them to continue studying math beyond high school.

A peek inside The Art of Philosophy

Delving into the intersections between artistic images and philosophical knowledge in Europe from the late sixteenth to the early eighteenth centuries, The Art of Philosophy shows that the making and study of visual art functioned as important methods of philosophical thinking and instruction. From frontispieces of books to monumental prints created by philosophers in collaboration with renowned artists, Susanna Berger examines visual representations of philosophy and overturns prevailing assumptions about the limited function of the visual in European intellectual history. Take a peek inside:

Jan C. Jansen and Jürgen Osterhammel on Decolonization

DecolonizationThe end of colonial rule in Asia, Africa, and the Caribbean was one of the most important and dramatic developments of the twentieth century. In the decades after World War II, dozens of new states emerged as actors in global politics. Long-established imperial regimes collapsed, some more or less peacefully, others amid mass violence. Decolonization by Jan C. Jansen and Jürgen Osterhammel takes an incisive look at decolonization and its long-term consequences, revealing it to be a coherent yet multidimensional process at the heart of modern history. Recently, the authors answered some questions about their new book:

You describe the dissolution of colonial empires as a major process of the twentieth century. What makes decolonization important?

In a way, decolonization is both among the most overrated and underrated historical processes of the twentieth century. On the one hand, many contemporaries pinned high expectations to the end of colonial rule: a new age of social and international equality, post-racism, peace, empowerment of the South, economic redistribution, cultural self-determination, democracy, technological progress, etc. Many of these expectations did not, or only partially, materialize. Hierarchies and inequality continue to shape the relations between formally independent states. It is thus only natural that many see decolonization through the prism of historical disappointment and disillusion. They regard decolonization as a failure. Yet we also have to see what decolonization did change: It dramatically altered the norms that govern the word-wide relations between nations and peoples. While in the late 1930s large parts of the world population still lived in territories that were under alien rule, this has become an anomaly in the present time. Racial hierarchy is no longer an accepted structuring principle of world order. This fundamental normative change is a major dimension—and yes, also an achievement—of the decolonization era. In general, it is important to go beyond these narratives of failure and success and to understand decolonization as a fundamental restructuring—and geopolitical fragmentation—of the international system. This is a perspective we put forward in the book.

How do you explain this international sea change?

This is a question that many contemporaries and witnesses of decolonization were already debating, and today’s historians and political scientists have inherited several ways of explaining the end of colonial rule: that the colonial powers simply could not stem against the rising tide of national liberation movements, that the new postwar international scene of the Cold War and international organizations forced Europe’s colonial powers to give up colonial rule, or that the colonial powers, in association with influential big business interests, realized that they could pursue their interests in more cost-effective ways than colonial rule, the classical “neo-colonialism” theory. In our book, in line with today’s excellent scholarship, we try to avoid overtly simplified models. Decolonization was a multifaceted and complex historical process, and its sheer geographical breadth should caution us against one-factor-theories. The book seeks to provide an analytical grid that takes into account various levels of historical action (local, imperial, international) and time frames. This grid may be used by our readers to analyze and describe specific cases, and may also help to explain decolonization in comparative perspective.

How irreversible is this process, in light of the current international scene? Are there no clear signs that the international order marked by decolonization is coming to an end?

Decolonization never did away with power structures between nations and peoples. Rather, it changed the ways in which these hierarchies are arranged and exercised. The formally sovereign nation-state—and no longer the empire—has become the basis of the international system. Despite the current renaissance of “spheres of interest” and “interventions,” as worrisome as these tendencies are, we do not see the reemergence of internationally codified hierarchies between “metropoles” and “colonies.” To be sure, the post-1989 international order has been under great pressure. Yet, there are no historical precedents for the reappearance of once collapsed empires. If current talk of a “Greater Russia” really leads to Russian “re-imperialization” remains to be seen. In that case, Russian ambitions will eventually clash with a self-confident China, ironically its old Asian rival, which, by the way, has never really ceased to be an empire. Elsewhere, the rise of xenophobic and racist movements throughout the Western world hardly seems to be inspired by the desire to be again at the pinnacle of a diverse and multi-ethnic empire. These movements want to minimize interaction with what they conceive as the inferior and dangerous other (be they Syrians, Eastern Europeans, or Mexicans); their new symbol is “the Wall.” Colonial re-expansion would necessarily go in a different direction.

You also argue that decolonization marked “a crucial phase in West European nation-building.” What do you mean by this?

Of course, decolonization did not bring about new European nation-states. This happened in the global South. Yet, it did have a considerable impact on the European metropoles, and also on Japan, which had built up its own colonial empire in Asia from the late nineteenth century on. These metropoles were closely tied to their overseas possessions, and it is one of the paradoxes of the decolonization era that such ties intensified at the very moment of imperial demise. After the Second World War, Great Britain and France, the two leading colonial powers, sought to facilitate mobility within their imperial spheres and set up, by today’s standards, relatively liberal citizenship laws for people from their respective empires. Decolonization, in this context, came as no less than a rupture in longstanding geopolitical orientations. It set off a new phase in European nation-building, a sort of nation-building by way of contraction. The metropoles had to dissolve or redefine the many—economic, political, social, also mental—ties to their respective empires. In light of increased immigration from their former colonial territories, they also had to redefine what it meant to be British, French, or Dutch. Though not produced by the end of empire, European supranational integration became enmeshed in European decolonization: the postcolonial European nation-states started to focus on Europe and the European market, which more than made up for their losses in former imperial trade. Great Britain, marked by a long-standing ambivalence toward continental Europe, made its first attempt to join the European Common Market in 1961, after the disaster of the Suez crisis and at the apogee of African decolonization. In a way, the 2016 “Brexit” vote to drop out of the European Union concluded this period of postimperial British supra-nationalism.

How present is the history of decolonization today?

Remnants of the colonial past and the decolonization era are pervasive. They remind us that our current world was built out of the ruins of empire. For example, a large portion of international borders between states, including the conflicts they sometimes nourish, have been the result of colonial rule. Decolonization basically enshrined most of them as the borders between sovereign nation-states. Some of the most troubling conflicts in the world—such as the Israeli-Palestinian conflict or the conflict between Pakistan and India—can be traced back to the decolonization era. Yet, notwithstanding the many apparent links, assessing the long-term impact of decolonization and the colonial past remains a tricky operation. Postcolonial countries have taken very different trajectories, sometimes starting from the same colonial system. Consider the two Koreas which had been under Japanese rule and which took diverging paths. The Syrian civil war, to cite another case, can hardly be seen as the ineluctable result of Franco-British quasi-colonial rule in the Middle East during the interwar years.

While the impact of the colonial past and the decolonization process may be fading with time, memories relating to this period have experienced a boom over the past two decades. Certainly, many episodes of the decolonization period remain largely forgotten. Who remembers the bloody repression of a major insurrection in Madagascar in 1947–49? Yet, debates about the colonial past and its end have attracted a great deal of attention not only in formerly colonized countries, but also in Japan and in many European countries. These memories have even become a concern in the diplomatic world. Internationally concerted efforts at remembering the effects—and the many victims—of colonial rule, similar to what we have seen with regard to the Holocaust or the world wars, however, are still no more than a wild dream by some historians.

Why did you write this book?

Decolonization has become an important topic in international historical scholarship, a development not completely detached from the memory boom we just talked about. Over the past two decades, historians and social scientists around the world have worked at piecing together a complex picture of this process and its reverberations. In many cases they have unearthed new archival evidence, a lot of which has only recently become accessible. Decolonization is in the process of turning into a highly productive—and specialized—research field. The wealth of new empirical studies, however, has been rarely accompanied by attempts at synthesis or general interpretation. The book offers such a broader survey. We sought to write it in a clear, accessible prose which addresses students and scholars, but also readers from outside the historical profession who are interested in this process.

Craig Clunas on Chinese Painting and its Audiences

ClunasWhat is Chinese painting? When did it begin? And what are the different associations of this term in China and the West? In Chinese Painting and Its Audiences, which is based on the A. W. Mellon Lectures in the Fine Arts given at the National Gallery of Art, leading art historian Craig Clunas draws from a wealth of artistic masterpieces and lesser-known pictures to show how Chinese painting has been understood by a range of audiences over five centuries, from the Ming Dynasty to today. Recently, Clunas took the time to answer some questions about the book.

There are lots of books about Chinese art, what’s the particular scope of this one?

CC: This book isn’t about the whole of Chinese art, but it looks at the important art of painting in China over the last five hundred years or so, from the Ming Dynasty (1368-1644) to the very recent past. It does it not from the point of view of the creation of Chinese painting but through a history of looking at it, and a history of the types of viewers who have formed the very diverse audiences for it over those centuries.

If I don’t know much about Chinese culture, will I be able to understand this book?

CC: I hope anybody interested in art can get something from this book. It has its origins in a lecture series, the A. W. Mellon Lectures in the Fine Arts, held regularly at the National Gallery of Art in Washington, DC, since 1953. In 2012 I gave these lectures (with the same title as the book); that’s only the second time in over sixty years that art from China has been the focus of a Mellon Lecture series. So I was very conscious of addressing a non-specialist audience, of people with an interest in the visual arts generally but without any specific expertise, and I’ve tried to keep the technicalities to a minimum in the main text, while still providing the evidence for other scholars to judge the strength of my arguments. When people say, ‘I don’t know anything about Chinese art,’ they often in fact already have a strong set of preconceptions, and I want to dispel some of these by showing the actual variety of painting being produced over a long time span, including work made in China in the past which tends to get left out of the category called ‘Chinese painting’ today.

How would you break down the main argument? 

CC: Obviously, back in the sixteenth century people in China who viewed a work by a famous painter of the day, or an old master from the past, didn’t think of what they were looking at as ‘Chinese painting.’ To them, it was just ‘painting.’ Today, whether in the Chinese-speaking world or outside it, the category ‘Chinese painting’ is the meaningful one we use to describe both historic painting and contemporary work of certain kinds. The book looks at how this came about, and shows how it was through the actions of viewers that this cultural category was formed, concentrating on certain kinds of pictures and marginalizing others. I’m claiming that the understanding of Chinese painting in some ways ran before it could walk, making big generalizations about the subject before much of the detailed work was done. These generalizations then fed into art history as a whole, where ‘Chinese painting’ stands as probably the major counter-example to the western tradition of art. I’m arguing here that the category ‘Chinese painting’ isn’t a timeless essence of Chinese culture, or an imposition on China from outside, but the result of a complex set of historical processes involving different types of audiences.

How does the book do this? 

CC: Firstly, by showing a fresh and broad set of images, you can’t write about pictures without showing them! The book is very heavily illustrated; it includes some familiar paintings which everybody already interested in the topic might recognize (though I hope they are talked about in a new way), but it also has lots of unfamiliar images, pictures which haven’t been widely reproduced before. I hope every reader will see something surprising and something beautiful. At the book’s heart are a sequence of what to me are really interesting paintings of different types of people – men and women, emperors and merchants, scholars and gallery-goers – looking at paintings. These pictures which take viewing as their subject can tell us a lot. They are at the core of a sequence of chapters which roughly speaking takes the topic from the fifteenth century to our own time, looking at a number of ideal audiences for Chinese painting; I’ve called these: the gentleman, the emperor, the merchant, the nation, the people. I’ve tried to balance analysis of the images themselves with the context in which they were produced, and to look at audiences both inside and outside China, which go back a lot longer than people might imagine. I’m obviously dependent on the specialist scholarship of other writers, and I’ve tried to pull together some of this work to give readers who might be interested in knowing more about a particular topic a sense of some of the great work being done now on Chinese painting. You can now read extensively in English about Chinese painting theory and criticism, and the lives of individual artists, over a broad time span. I’d be pleased if this book made people just a bit more aware of that great body of knowledge, and of the sheer scale of China’s artistic production.

How do you think this book might be received in China? 

CC: I’ve written other books on Chinese art, mostly of the Ming period, which have been translated into Chinese, and what I find interesting (and a bit surprising) is how some Chinese readers find contemporary resonances in books which I thought of when I wrote them as being ‘just’ about history. So I’ve come to accept that the history we write is never ‘just’ about the past. I’ve also learned (and this would be one of the main arguments of the book) that it’s wrong to imagine some homogeneous ‘Chinese view’ of painting or anything else, as if everybody in that huge country thought the same way. I hope some readers there might find it intriguing, and that even if they don’t like its way of arguing they would recognise the respect I feel for one of the world’s great bodies of art and human creativity.

How do you see the story of Chinese painting and its audiences developing in the future? 

CC: Painting, whether in brush and ink or oil on canvas, is only one of the practices of the visual arts in China today, but it remains an extremely important one. This is not least because the boom in the art market in China makes works of both past and present hugely valuable commodities. It seems pretty unlikely to me that the significant collections of Chinese painting outside China (whether in museums or in private hands) will grow very much in the future, the gravitational pull of the Chinese market is now just too strong. But the digital reproduction of artworks, which is proceeding now at a terrific pace, may mean that the physical location of paintings will matter less and less, their audiences will become more global and the composition of these audiences will get more and more diverse. That’s perhaps going to make it harder and harder for a restrictive definition of ‘Chinese painting’ to sustain itself, and maybe in time it will just be part of something called ‘painting’ again, or – who knows – even the dominant strand within it.

Cass Sunstein on the echo chamber and his new book, #Republic

SunsteinSocial media gives us ways to nurture ever more elaborate online communities, but is it friendly to the kind of democracy diverse societies need? In #Republic: Divided Democracy in the Age of Social Media, Cass Sunstein, the New York Times bestselling author of Nudge and The World According to Star Wars, shows exactly how today’s Internet is driving political fragmentation, polarization, and even extremism—and what can be done about it. Recently, Sunstein answered a few questions about his timely new book.

Why did you write this book, and how does it relate to your previous work?

Well, we are obviously in a time of national division. The splits between Americans across political lines are striking and disturbing, and there’s a lot of division and mutual misunderstanding out there. There is distrust and anger as well. Social media contributes to those splits. So I wanted to get hold of what is a really serious problem in a nation that aspires to E Pluribus Unum. The book grows out of my previous books on the general subject—but the media environment has changed so rapidly that some of the central arguments, e.g. about Twitter and Facebook, are entirely new.

What new threats to democracy does the internet pose now that it didn’t pose, say, five years ago? Haven’t people always sorted themselves into like-minded groups?

We used to have a much larger role for general interest intermediaries, such as the Wall Street Journal and the New York Times. That’s diminished, and with it, trust in them has diminished too. The use of niches—especially for people who are politically engaged—is pretty dramatic. Hashtag Nation (#Nation) isn’t really something we’ve seen before. I wouldn’t want to say that things are getting worse, but they’re getting differently bad.

We’ve all heard the term “echo chamber,” perhaps particularly in the recent election cycle. Can you talk a bit about this idea and the implicit dangers?

Echo chambers breed extremism. If you hang out with like-minded people, you’ll get more confident and more extreme—and the group will get more unified. Pretty soon, people in different echo chambers live in different political universes. That makes problem-solving really hard, and it makes enmity really easy. My own work in the White House showed me the importance of focusing on objective truths and of not insulating oneself—echo chambers are destructive to those endeavors.

How can the internet be made friendlier to democratic deliberation?

A big question. Let’s start with Facebook: It should redo its News Feed so as to ensure that there’s less in the way of informational cocoons. Let’s end with each of us: We should make choices so that we hear lots of points of view, including from people we think we disagree with. If you can’t learn something from someone with a very different political orientation, you’re missing a lot. You’re not an ideal citizen, or close to it.

What kind of democracy is needed in diverse societies, and how can your book help us to get there?

We need deliberative democracy—one in which people deliberate with people who are unlike themselves, and learn from them. We need to put a premium on science and facts. We need serendipitous encounters with people and ideas that we would not choose to engage. We need a lot more technocracy, not less. The book might have a few ideas on those subjects.

Cass R. Sunstein is the Robert Walmsley University Professor at Harvard Law School. His many books include the New York Times bestsellers Nudge: Improving Decisions about Health, Wealth, and Happiness (with Richard H. Thaler), The World According to Star Wars, and #Republic: Divided Democracy in the Age of Social Media.

Tony Smith on how Woodrow Wilson shaped America’s foreign policy

Why Wilson Matters by Tony SmithThe liberal internationalist tradition is credited with America’s greatest triumphs as a world power—and also its biggest failures. Beginning in the 1940s, imbued with the spirit of Woodrow Wilson’s efforts at the League of Nations to “make the world safe for democracy,” the United States steered a course in world affairs that would eventually win the Cold War. Yet in the 1990s, Wilsonianism turned imperialist, contributing directly to the invasion of Iraq in 2003 and the continued failures of American foreign policy. In Why Wilson Matters: The Origin of American Liberal Internationalism and Its Crisis Today, Tony Smith traces how Wilson’s thinking about America’s role in the world evolved in the years leading up to and during his presidency, and how the Wilsonian tradition went on to influence American foreign policy in the decades that followed. Smith recently took the time to answer questions about his book.

How does Woodrow Wilson’s foreign policy (1913-1921) relate to today’s world?

TS: Wilson never articulated a grand strategy for the United States. Still, his two terms in office, and especially his design for the League of Nations, laid out concepts for how to “make the world safe for democracy” that came to life with the challenges Washington faced to win the peace after victory in World War II. The package of Wilson’s proposals for a system of world peace called for an alliance of democratic governments, working to promote an integrated international economic system, through multilateral agreements that included first and foremost collective security, all maintained under American leadership. What at first would be a Pax Americana would in time become a Pax Democratica. The result is what we call “Wilsonianism,” the American variant of liberal internationalism. We can distinguish a “preclassical” stage of liberal thinking that goes back to our Revolution, a “classic” period with Wilson, a “hegemonic” stage during the cold war, and an “imperialist” phase that began in the 1990s. This last stage is best called “neo-Wilsonianism.”

Was President George W. Bush the heir of the Wilsonian mantle in world affairs?

TS: Certainly the Bush Doctrine (defined as the National Security Strategy of the United States in September 2002) seemed to show continuity between Wilson’s thinking and that of the Bush administrations of 2001-2009. The key difference lay in the defensive character of classical and hegemonic American liberal internationalism and the offensive posture of neo-Wilsonian imperialism. The neo-Wilsonian belief that democracy was a “universal value” that had “universal appeal” such that the United States could embrace a “just war” doctrine that overthrew the Westphalian system of state sovereignty in terms of a “responsibility to protect” peoples everywhere from autocratic government would never for a moment have been entertained by Wilson. Wilson did not march on Mexico City in 1914, nor on Moscow or on Berlin in 1918. By the same coin, he would surely not have approved the attack on Baghdad in 2003, nor is there reason to think he would have celebrated the April Spring eight years later.

Why, then, is Wilson’s name so often associated with American imperialism?

TS: At the root of the problem is the failure to study Wilson’s political thinking about the origins and character of democratic government developed during the decades when he was one of this country’s leading social scientists, ideas he later followed as president. The result is that American liberal internationalism has lacked a clear identity to give it a compass in foreign relations after the collapse of the Soviet Union in 1991. To call Wilson, as so many have, “a crusader,” “messianic,” and “utopian” is simply to misunderstand the prudent restraint he repeatedly showed in thinking that democratic government would quickly, easily, or indeed ever at all expand worldwide. Yes, he was “idealistic” and “moralistic” in thinking democracy was the best form of government for peoples capable of enjoying its blessings of liberty. But a utopian, and so an imperialist, he never was. Let’s call him a “realistic liberal.”

Why does all this matter?

TS: The American tradition of human rights and democracy promotion, like that which sponsors open economic relations, all in the name of making the world safe for democracy, has badly overplayed its hand. Its belief that our way was the only way led to a clash of civilizations the fruits of which we can see on every side, from the Muslim world, to China and Russia to economic inequality at home. The tragedy is that a way of thinking that did so much to establish the strength of the free market democracies between the early 1940s and the early 1990s should have been the source of its own undoing is an irony whose logic needs to be grasped. Here lies the explanation for how the greatest successes in the Republic’s history in foreign affairs—going from the creation of the Bretton Woods System to the North Atlantic Treaty Organization, passing by occupation policies for Germany and Japan—should give way to a change in its course that would lead to the invasion of Iraq under Bush and the surge in Afghanistan and enthusiasm about the Arab Spring under Obama –policies which now constitute the greatest defeats in our country’s history in world affairs.

Is liberal imperialism related to the economic crisis that has best the world since 2007?

TS: Most certainly it is. To read the criticisms of Economics Nobel Prize winner Joseph Stiglitz is to see the logic of Wilson’s thinking applied to our day with the same concern from American power and American democracy being steadily eroded by what Wilson called “predatory” capitalism. He feared its machinations globally, and not only domestically. Wilson was right.

What can be done?

TS: Neo-Wilsonianism is now deeply embedded in American elite institutions. The neoconservative takeover of the Republican Party in the 1990s bears much of the blame for popularizing and militarizing the Wilsonian tradition. However, the neoliberal movement within the Democratic Party did most of the intellectual heavy-lifting in the development of this thinking, as can be seen from a review of the Obama years and the policies advanced by Hillary Clinton and John Kerry. The international regulation of the capitalist world and the growth of a national security state simply have too much momentum behind them for us to have much confidence in a progressive future. That said, the faith of an earlier day returned under FDR with astonishing success and may yet be able to light the future before it is too late. Nation- and state-building that Washington likes to discuss so much with respect to our efforts to reform peoples abroad might better begin at home. From income inequality, to campaign finance reform, to prison conditions there should be quite enough here and with our democratic partners to keep us busy. “Physician, heal thyself.”

Eric H. Cline on the story of archaeology

In 1922, Howard Carter peered into Tutankhamun’s tomb for the first time, famously exclaiming, “I see wonderful things.” In a lively and essential introduction to the story of archaeology, Three Stones Make a Wall by well-known archaeologist Eric H. Cline, takes us from the pioneering digs of the eighteenth century, to Carter’s legendary discovery, to the exciting new discoveries being made today. Recently, Cline took the time to answer a few questions about his book, his most interesting discoveries, and provide insights into how excavations are actually done.

When did you become interested in archaeology? What inspired you to become an archaeologist?

EC: As I say at the beginning of this book, when I was seven years old my mother gave me a biography written for children called The Walls of Windy Troy. It was about Heinrich Schliemann, the man who discovered ancient Troy. After reading it, I announced that I was going to become an archaeologist. When I graduated from college with a degree in Classical Archaeology, my mother gave me the same book again.

How many digs have you been on and where?

EC: I’ve been going on digs since I was a sophomore in college. So far I’ve participated in more than thirty seasons of archaeological excavations and surveys, mostly in Greece and the Middle East, including Egypt, Jordan, and Israel. Most of them were at places that nobody but archaeologists have ever heard of, like Ayios Dhimitrios in Cyprus and Palaiokastro in Crete, which are both Bronze Age sites dating back to the second millennium BCE, but ten of those seasons were spent digging at Megiddo in Israel, which people have heard of because it is biblical Armageddon. I’ve also dug a bit in the United States, in both California and Vermont. There was a time, back when I was in college and my early years in graduate school, that I would pick a country which I hadn’t visited before and find an interesting dig there to work on; then I would go over early and come back late, so I had time to travel in the country for a few weeks both before and after the dig. That’s what I did in both Jordan and Egypt, for example. But now I’ve been working at sites in Israel for pretty much the last 20 years, since about 1994.

What’s the best thing that you’ve ever found on a dig?

EC: The first great thing that I found on a dig was a petrified monkey’s paw. I tell the story at the beginning of the book, but it was on that first dig, when I was a sophomore in college. It was a Greek and Roman site in the north of Israel, called Tel Anafa. The University of Michigan was running the dig. So, one morning, I uncovered an object that was buried in the dirt. But, I didn’t uncover it so much as hit it accidentally and at such an angle that it flew up in the air. When it was in the air, almost in slow motion, I looked at it and thought, “oh, a petrified monkey’s paw!” But, by the time it landed, I knew that was ridiculous, because there hadn’t been any monkeys back in Greco-Roman Israel. It turned out to be a little bronze figure of the Greek god Pan (the guy with horns who plays a double flute and traipses through the forest), which would have originally been attached as an ornament to a wooden chair. The chair is long gone, but the little bronze figure was lying there, just waiting for me to find it more than 2,000 years later. It’s now in a museum in Israel. But, the second great thing, which is probably actually the best thing that I’ve ever found, is the wine cellar of a palace that is almost 4,000 years old. We’re actually still digging it and will be there this coming summer of 2017. It’s a Canaanite palace at Tel Kabri, in northern Israel, where we have found the oldest and largest wine cellar from the ancient Near East. So far we have found more than a hundred storage jars, each about three feet tall, which held the equivalent of thousands of bottles of wine in today’s terms. We have done Organic Residue Analysis on the pottery sherds that make up the jars and know that it was mostly red wine, with additives like honey, juniper berries, and mint in it. I talk about it in the book as well, including our hope to recreate the wine some day.

What is the most misunderstood thing about archaeologists?

EC: We don’t dig up dinosaurs; those are paleontologists. We dig up the remains left by humans, as well as the remains of humans themselves.

Aren’t there other introductory books on archaeology out there? What do you do differently?

EC: This is a pretty fast read and is designed so that the reader can skip around in it very easily and read it in any order that they want. In addition to discussing many of the world’s most famous sites and archaeologists, there are several chapters on how archaeologists actually find sites, dig them up, and date the artifacts that they find. I have also included anecdotes and stories from my own experiences, which livens things up a bit, such as the time that I thought I found a petrified monkey’s paw.

Who do you expect will enjoy reading this book – that is, who is your intended audience?

EC: I hope that everyone – from age seven to seventy – will enjoy reading this book. It is intended for anyone and everyone, from complete novices to those who already know a lot but want to know even more. I also hope that it inspires someone, somewhere, to become an archaeologist.

What do you think is the book’s most important contribution?

EC: Apart from introducing people to archaeology in general, I have also included parts that will hopefully allow people to be a little more discerning when watching some of the shows on TV and reading about some of the claims that are occasionally made in the media. In addition, I discuss some of the problems that we currently have with the looting of archaeological sites in various parts of the world. This is a situation that should be of concern to all of us, since these sites are our shared heritage and are a limited resource; once they are gone, they disappear forever.

What is the one thing that you hope people will remember after reading your book?

EC: There is no need to ever invoke aliens in order to explain anything that archaeologists find.
