Our new History of Science and History of Knowledge catalog includes a fascinating account of the spread of Einstein’s theory of relativity, a timeless defense of the value of basic research, and a new history of archaeology from Eric Cline.

In The Road to Relativity, Hanoch Gutfreund and Jürgen Renn explored Einstein’s original paper, “The Foundation of General Relativity”. Gutfreund and Renn’s new book, The Formative Years of Relativity, follows the spread and reception of Einstein’s theory, focusing in particular on the Princeton lectures that formed the basis for his 1922 book, The Meaning of Relativity. Drawing on Einstein’s letters and contemporary documents, many of which are reproduced within, The Formative Years of Relativity provides invaluable context for perhaps the most important scientific breakthrough of the twentieth century.

The Formative Years of Relativity by Hanoch Gutfreund and Jurgen Renn

In 1939, Abraham Flexner, founding director of the Institute for Advanced Study, wrote an essay on The Usefulness of Useless Knowledge arguing that basic research into fundamental questions has always driven scientific innovation and warning against focusing too narrowly on immediately “useful” knowledge. In a time where pressure is constantly increasing on researchers to apply themselves to practical problems, we are pleased to bring Flexner’s enduring essay back into print, accompanied by a new essay from the current director of the Institute he founded, Robbert Dijkgraaf.

We can think of no better person to present the history of archaeology than Eric H. Cline, author of 1177 B.C. Cline’s Three Stones Make a Wall gives a vivid account of the legendary excavations and the formidable personalities involved in archaeology’s development from amateur’s pastime to cutting edge science. As capable with a trowel as he is with a pen, Cline draws on his three decades of experience on digs to bring the how and the why of archaeology to the page alongside the history.

Peter Ungar on Evolution’s Bite

UngarWe carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution’s Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present a remarkable investigation into the ways that teeth—their shape, chemistry, and wear—reveal how we came to be. Ungar recently took the time to answer some questions about his new book.

Why do paleontologists care so much about teeth? What makes them so special?

PSU: Paleontologists care about teeth because oftentimes, that’s all we’ve got of extinct species to work out details of life in the past. Teeth are essentially ‘ready-made fossils,’ about 96% mineral, so they survive the ages much better than other parts of the body. They are special because they come into direct contact with food, and can provide a bridge to understanding diet in the past. We can tease out the details by studying their size, shape, structure, wear, and chemistry. Teeth connect us to our ancestors, and them to their worlds. I like to think of nature as a giant buffet of sorts. I imagine animals bellying up to the sneeze guard on this biospheric buffet with empty plate in hand. Teeth can teach us about the choices they make; and it’s those choices that help define a species’ place in nature. As the old adage goes, you are what you eat. Teeth are important because they can help us understand relationships between animals in the past and the worlds around them, and about their—and our—evolution.

Why do we have so many problems with our teeth today? Why do we get cavities, require braces, and have impacted wisdom teeth?

PSU: Think about how extraordinary your teeth are. They have to break food, without being broken themselves, up to millions of times over your lifetime. And they have to do it built from the very same raw materials as the foods you are eating. Nature is truly an inspired engineer, and it’s remarkable they last as long and function as well as they do. But they’re not perfect. Most of us today get cavities, and many of us have crooked front teeth, and impacted wisdom teeth. This is largely because of our diets. We eat mostly soft foods, loaded with highly-processed carbohydrates, especially refined sugars. Cavities form by erosion from acids produced by plaque bacteria. Feeding those bacteria diets high in carbohydrates, especially sugars, means more cavities. Also, when we eat soft foods as children, we don’t exercise our jaws enough to stimulate the growth they need to make room for all our teeth. The result is crowded lower incisors, uppers that jut out over the lowers in the front of the mouth, and impacted third molars in the back. It’s not that our teeth are too big for our jaws, it’s that our jaws don’t grow long enough to accommodate all our teeth. Most traditional foragers that eat tougher or harder foods have longer jaws, and so don’t suffer the sorts of orthodontic problems the rest of us have.

Do other species have these problems? If not, why are we so different?

PSU: I’ve seen cavities and evidence for gum disease in some non-human primates, particularly in species that eat a lot of fleshy, sugary fruit, but they’re much rarer than in us. There are very few early human fossils that provide evidence of dental disease in our distant past either. Again, it seems to be a mismatch between our diets today, and the foods that we evolved to eat. Our teeth are not designed for hamburgers and French fries, nor to be bathed in milkshake. If you want to see evidence of that mismatch, just smile and look in a mirror.

What was your motivation for writing a popular science book?

PSU: My PhD dissertation was 654 pages, mostly focused on a quarter of a square millimeter of the surface of some incisor teeth. Most academics are so narrow in their research focus that it can be difficult to see the forest for the trees. I wrote this book to give myself the big picture, to give me an appreciation of the larger context into which my own work fits. Also, no more than half a dozen people actually read my dissertation cover to cover, and that includes my mother. Academics often feel like they’re speaking, but no one is listening. I wanted to reach a larger audience. This book at first glance seems to be about teeth – but it’s really about the biospheric buffet, and how environmental change over deep time swapped out items and choices available to our distant ancestors. The take-home message is that large-scale climate swings winnowed out the pickier eaters among us, and drove our evolution. Teeth are our window through which to see it. The most important message here is that climate changes, and species have to change to accommodate or die. That’s why we’re here. It’s a timely, important lesson.

As a scientist who has spent the last three decades studying evidence for the evolution of human diet, what do you think of today’s “Paleolithic diet” trend? And what was the ancestral human diet, anyway?

PSU: I’m not a fan. I like pizza and bagels too much. Still, there’s little doubt that our ancestors did not eat such things; so it makes sense that a discordance between the foods we evolved to consume and what we fuel ourselves with today can wreak havoc on our bodies. Try putting diesel in a car built to run on regular gasoline (actually, don’t). And people do lose weight when they cut refined carbohydrates and processed sugars from their diets. We could well benefit from eating more like our Stone Age ancestors, with menus like those in some popular diet books—you know, spinach salads with avocado, walnuts, diced turkey and the like. I am not a nutritionist, and cannot speak with authority about the nutritional costs of benefits of Paleolithic diets—but I can address their evolutionary underpinnings. Think about it this way. Any diet that drains the body of fat reserves means not meeting daily caloric needs. It is difficult to believe that nature would select for us to eat only foods that don’t provide the nutrients required to maintain the body. In fact, the whole idea of the Paleolithic diet is problematic. Even if we could (and we can’t) reconstruct the glycemic load, fatty acid, macro- and micronutrient composition, acid/base balance, sodium/potassium ratio, and fiber content of foods eaten at a moment in time in the past, the information would be meaningless for planning a menu. All these nutrients varied with food availability over space and time, as items on the biospheric buffet table were swapped in and out, so focusing on a single point in our evolution is futile. We’ve been a work in progress for millions of years. What was the ancestral human diet? The question itself makes no sense.

Steven and Ben Nadler on Heretics!: An enlightening graphic novel

NadlerThis entertaining and enlightening graphic narrative tells the exciting story of the seventeenth-century thinkers who challenged authority to lay the foundations of modern philosophy and science and help usher in a new world. With masterful storytelling and color illustrations by father-son duo Steven Nadler and Ben Nadler, Heretics! offers a unique introduction to the birth of modern thought in comics form. These contentious and controversial philosophers—from Galileo and Descartes to Spinoza, Locke, Leibniz, and Newton—fundamentally changed the way we look at the world, society, and ourselves. Heretics! tells the story of their ideas, lives, and times in a vivid new way. Read on for a conversation between Steven and Ben about the process of working together on a graphic novel, their favorite illustrations, and what they each learned along the way.

Ben:  So Dad, tell me, what gave you the idea for us to do a graphic book together on modern philosophy?

Steven: Well, my editor at Princeton University Press had asked me to write a big new history of philosophy, perhaps with some illustrations done by you. But I wasn’t sure that was something I wanted to do. However, I was intrigued by the notion of doing something really creative with a history of philosophy in the seventeenth century, my specialty. And then, with you recently graduated from art school, I thought it would be really fun to do something together. And it was! Let me ask you: why did you want to do it?

Nadler

Ben: It was an offer I could not refuse. I was an intern in Seattle just out of RISD, but not really employed as an illustrator. So I was hoping this book would be a good way to get that career started. I was also part-way through a graphic novel that didn’t seem to have an end in sight, so the idea of doing a more collaborative project that had some structure and a deadline was appealing. Plus, it was a chance to bond with my father! What were your expectations going into it?

Steven: I was hoping that we could find an engaging and entertaining way to introduce a broad audience to a really interesting period of philosophy and a fascinating group of philosophers. I want this book to be read not just by professional philosophers and philosophy students, but general readers of all kinds, including high school and college students. It had to be really accessible and tell a good story. The hard part for me, in writing the text, was to avoid two extremes: on the one hand, being too dry and academic, and, on the other hand, being condescending and patronizing. I had to find the right balance between academic writing and simplistic popularizing. What was the hard part for you?

Nadler

Ben:  The hardest part was finding the right visualizations for some of the really abstract, conceptual and heady ideas that you wrote about. It’s one thing to draw biographical comics about philosophers, and another to try to illustrate Leibniz’s concept of “monads.”

Steven: Yes, I do remember your panicked phone call asking me what the hell a monad is.  We had to give a lot of thought to how to depict a monad visually, and I checked in with various colleagues to see if they had any ideas.  Everyone was kind of stumped.  I think you came up with the best solution.  The other tough challenge was how to illustrate a person’s soul (as distinct from their body). Again, I think you did a great job with that visually.  What’s your favorite page or chapter of the book?

Nadler

Ben: The page where the two guys are getting pushed out the window was really tough, I had to spend a whole day trying to get the perspective right. That might be my favorite illustration, because of how much work went into it and seeing the final pay-off. I also tend to like the later pages, after I settled into my drawing habits and improved over the year and a half we worked on the book. I completely re-drew the first twenty pages or so after everything else was finished, just to try to maintain a consistent look. What about you? I’m going to guess it’s God waving goodbye as the earth gets on the school bus.

Steven: Yes, I love that image of God waving goodbye to the world.  And the illustration of the defenestration is wonderful, really bold.  I also like the corpuscle in motion, roller-blading with headphones, in the section on Gassendi, and the image from the Newton chapter showing the earth and the moon being tugged toward each other by gravity as they hold on to the edges of the panel.  In the end, did you enjoy the experience of illustrating philosophy? It’s hard to do, and I think you did a brilliant job—but then again, I’m your father, and a little biased.

Nadler

Ben: Thanks, Dad! I did enjoy it, it was challenging and fun. I learned a lot about what makes a book come together. I especially liked researching and implementing all of the costume design and set pieces for 17th century Europe, it was a really immersive way to learn about western philosophy.

Steven Nadler is the William H. Hay II Professor of Philosophy and Evjue-Bascom Professor in the Humanities at the University of Wisconsin–Madison. His books include Spinoza: A Life, which won the Koret Jewish Book Award, and Rembrandt’s Jews, which was a finalist for the Pulitzer Prize.

Carol Graham on the optimism gap between rich and poor

GrahamThe Declaration of Independence states that all people are endowed with certain unalienable rights, and that among these is the pursuit of happiness. But is happiness available equally to everyone in America today? How about elsewhere in the world? In Happiness for All, Carol Graham draws on cutting-edge research linking income inequality with well-being to show how the widening prosperity gap has led to rising inequality in people’s beliefs, hopes, and aspirations. Recently, she took the time to answer some questions about her new book.

Why did you decide to write a book on unhappiness in the U.S.?

CG: This was a first for me, as I have spent much of my career exploring and writing about the causes and potential solutions to poverty and inequality challenges in developing countries. I took a modest change in direction about a decade ago and began to explore the determinants of happiness in countries and cultures around the world. This turn was driven by my findings of deep frustration among upwardly mobile low-income respondents in emerging market economies. What was most notable was the remarkably consistent patterns in the correlates of happiness across countries of all levels of development. I then found that happier people tended to have happier and more productive lives, and wrote one of the early papers on what happiness ’causes.’ Those findings have since been confirmed by several subsequent studies. Meanwhile, despite (or because of?) my grounding in development economics and origins in Peru, I have been increasingly concerned by the very large gaps between the incomes, opportunities, and lives of the rich and poor in the U.S. – a country with a reputation as the land of opportunity. As such, I decided to explore if and how those gaps were mirrored by differences in well-being and ill-being across the same groups in this book.

What is different about this book from the many recent studies of rising inequality of incomes and opportunities in the U.S.?

CG: While many economists, including me, have been discussing and writing about the downsides of increasing inequality in the U.S., interest in the topic was largely confined to academic audiences until very recently. And while the debate surrounding the 2016 elections brought inequality to the public’s attention, public understanding of actual trends in inequality and their implications remains very limited, in large part because of the complexity of the metrics used to measure it, such as Gini coefficients and 90/10 ratios. In the book I try and tell the same story from the perspective of well-being metrics, in the hopes that it might be a better way to explain the implications of inequality for economists and non-economists alike. One of the little known channels that I highlight is a beliefs and behaviors channel via which high levels of inequality – and large differences between those at the top of the distribution and the rest of the population – can act as a disincentive to investments in the future. This is because ‘success,’ as defined by the lives of those at the top, seems (and often is) out of reach for those at the bottom, making them less likely to make the difficult trade-offs to forego current consumption for the ‘promise’ of future outcomes.

What are your key findings for the land of the American Dream?

CG: Most markers of well and ill-being, ranging from life satisfaction to stress, are more unequally shared across the rich and the poor in the U.S. than they are in Latin America, a region long known for high levels of inequality. The most remarkable finding is that the belief that hard work can get you ahead in the future – a classic American dream question – is the most unequally shared metric. The poor in Latin America are almost four times as likely to believe that hard work will get them ahead than are the poor in the U.S. In contrast, the rich in the U.S. are more likely to believe that hard work will get them ahead than the rich in Latin America. Meanwhile, stress, a marker of ill-being, is significantly higher among the poor in the U.S. than the poor in Latin America. The stress which is typically experienced by the poor is related to constant negative shocks which are beyond individuals’ control. This kind of stress makes it hard to plan ahead, much less invest in the future, and is distinct from stress that is associated with goal achievement – which is more common among those with more means and control over their lives. These findings highlight very different incentives – and capabilities – for making investments in the future across the rich and the poor in the U.S.

Were there any other surprises?

CG: The most surprising of the findings were large gaps in optimism across racial cohorts, which did not run in the expected direction. In the fall of 2015 – about the same time as the riots against police violence against blacks in cities such as Ferguson and Baltimore – I found that the most optimistic group among the poor were poor blacks, followed by poor Hispanics. In contrast, poor whites showed signs of deep desperation. At roughly the same time, Anne Case and Angus Deaton published a study highlighting rising U.S. mortality rates driven by preventable deaths among uneducated middle aged whites. Since then, I have matched my desperation data/lack of optimism data with the mortality rate trends – by race and place – and find that the markers correspond quite closely. The most desperate people and places are poor and vulnerable middle class whites in the rust belt, where available jobs are shrinking due to the hollowing out of manufacturing and people are extremely isolated by distance and climate. In contrast, cities, which are more racially diverse, are healthier, more hopeful, and happier. These trends help explain some of the anger and desperation that drove the 2016 election results in the U.S. and also mirror those which influenced the U.K.’s Brexit referendum and an unexpected (and economically costly) decision to leave the European Union.

What are the potential solutions?

CG: There is no magic bullet to the narrowing the gaps between the lives – and well-being – of the rich and the poor in the U.S. And while desperation among poor and downwardly mobile whites is clearly a concern, there are still momentous challenges facing poor – if more optimistic – minorities. In the book I highlight a range of policies – from better vocational training, to more widely available pre-school and quality public education, to improving our safety net so that it does not stigmatize recipients and at the same time leave the non-working poor behind. I also provide examples – from novel experimental data – of interventions which raise aspirations and hope among the poor and disadvantaged, thereby encouraging investments in the future. I conclude by highlighting the important role that well-being metrics can and should play in official statistics, by tracking the health and well-being of our society, as the U.K. is already doing. The metrics can, for example, identify pockets of desperation before mortality rates increase, and highlight community level practices which increase well-being among the vulnerable, among many other things.

Global Ottoman: The Cairo-Istanbul Axis

First published in Global Urban History as ”Global Ottoman: The Cairo-Istanbul Axis” by Adam Mestyan. Republished with permission.

On a Sunday at the end of January 1863 groups of sheikhs, notables, merchants, consuls, and soldiers gathered in the Citadel of Cairo. They came to witness a crucial event: the reading aloud of the imperial firman that affirmed the governorship of Ismail Pasha over the rich province of Egypt. The firman was brought by the Ottoman sultan’s imperial envoy. After the announcement, which occurred, of course, in Ottoman Turkish, Ismail held a reception. Local Turkic notables and army leaders came to congratulate and express their loyalty. A few months later, in April 1863, they received Sultan Abdülaziz in person in Alexandria—something that had not occurred since the Ottomans occupied Egypt in the sixteenth century. From Alexandria the sultan took the train to Cairo. This was the first trip of a caliph on the tracks.

But what did Ottoman mean exactly in Egypt? My forthcoming book, Arab Patriotism: The Ideology and Culture of Power in Late Ottoman Egypt, examines the significance and meaning of the Ottoman imperial context for the history of Egyptian nationalism. The book demonstrates the continuous negotiation between Turkic elites in Egypt and local intellectuals and notables bound by collective, albeit contested, notions of patriotism. There was an invisible compromise through the new representations and techniques of power, including the theater. This local instrumentalization and mixing of urban Muslim and European forms is the backstory to new political communities in the Middle East. Importantly, the Ottoman connection was an urban one: imperial elites are urban elites and rural elites had to become urban ones in order to maximize their interests by the fin-de-siècle.

So, what does the Ottoman framework mean for urban historians of the Arab world and in particular of Egypt? Such a framework does two important things: as Ehud Toledano underlines, it points to the delegated power of the governors by the sultan; and it reveals that new (elite) consumption practices and technologies spread not only by direct contact between local and European actors but also by the imperial mediation of Istanbul, or vice versa, by local provincial mediation to the capital. The Ottoman Empire guaranteed the network of free and safe trade, and movement between cities still in the nineteenth century. These basic features of the Ottoman context remained in place even after the British occupation of Egypt until 1914.

Such a perspective does not diminish the factual power of European empires and their military interventionism to protect their economic interests. On Barak eminently showed that the first train line in Egypt was crucial for British rule in India in the 1850s. European technologies and new sources of energy (coal, electricity) also helped the Ottomans to reach their far-flung domains quickly (remember the sultan arrived via train in Cairo). These instances, however, do not mean that the sultan’s (or his representatives’) power was usurped by Europeans completely until the 1870s. “Bringing the Ottomans back in” destabilizes the bifurcated view of West and East by highlighting a plural system of power just before the scramble for Africa.

We should not read “Ottoman” as “old” in contrast to the European “new.” This is the exciting moment of the Tanzimat reforms in the Ottoman Empire, in which new technologies were “Ottomanized” to a certain extent, next to legal changes. There was an Ottoman elite modernity representing novelty to the provincial populations which had milliard connections to bourgeois practices globally.

Interior of the Mosque of Silahdar Agha, picture by the author.

In the context of nineteenth-century Cairo, the most aesthetic representations of power were often formulated in terms of Ottoman sovereignty—a sovereignty that the pashas of Egypt wished to renounce but never did. Among these Ottoman features, one can see the mosque of Mehmed Ali in the Citadel. Doris Behrens-Abuseif reminds us that this mosque represents both Mehmed Ali’s power and Ottoman imperial aesthetics. It dominates the city’s skyline to this day. The pasha’s military elite brought late Ottoman baroque to Cairo: just look at the mosque of Sulayman Silahdar Agha in al-Mu‘izz Street and other smaller Ottoman mosques, schools, fountains, and palaces around the city. Though featuring local characteristics (“the Egyptian dialect of Ottoman architecture”), these structures are unmistakably Istanbulite and were built prior to or in the 1870s. A particularly interesting interplay between Ottoman and European aesthetics, hygienic considerations, and capitalism occurred in the creation of various public and private gardens in nineteenth-century Cairo and Alexandria. Buildings of power such as the Abdin Palace were likely conceived in a competition with the Ottoman capital (there the Dolmabahçe Palace was new in the 1850s) restaging political representation in a “modern” architectural idiom.

Socially, there are some who understand the Ottoman presence in Cairo (and in Egypt in general) as “The Turks in Egypt,” to quote the useful but somewhat misleading publication title of Ekmeleddin Ihsanoğlu. There were certainly ethnic Turks in Ottoman Egypt. The local population looked at the quite cruel Ottoman military ruling class as the “Turks” (al-Atrāk). Yet, in nineteenth- and early twentieth-century Cairo, there were many Ottoman Armenian, Greek, Jewish, Albanian, Bulgarian, and Circassian families whose primary or secondary language was some version of Turkish and who had family or economic ties to various Ottoman cities in Asia and Europe. Their leading members rapidly transformed themselves into Franco- and Italophone “cultural creoles” (to use Julia Clancy-Smith’s expression), who forged new identities precisely by distancing themselves from their Ottoman past. Another identity strategy, not necessary exclusive of the previous one, was nationalism.

Ismail Pasha, Library of Congress.

The Cairo Ottoman elite was connected to Istanbul and was part of the imperial order. There was an elite Ottoman global network. The rulers, their families, and various relatives lived in both cities (later in Paris and in Switzerland). Every day, orders, secret reports, gifts, and personal staff arrived from Istanbul in Alexandria to be transported to Cairo and vice versa. From the 1860s onwards, this political and leisure traffic was facilitated by the Aziziya steamship company. The landowning-ruling households developed significant economic investments in between both cities, not to mention the large yearly tribute Egypt paid to the sultanic treasury. Ottoman treaties applied to Egypt to a significant extent. In the 1860s, as Nicolas Michel argues, the Ottoman Empire not only remained skeptical of the Suez Canal, but actually intervened in its construction. Ismail Pasha himself is usually remembered for the Suez Canal opening ceremony and associated follies which led to foreign control of Egyptian finances. He was, however, also an Ottoman man, part of the imperial elite and intimately familiar with Istanbul where he lived and where he eventually died. His mother, Hoşyar, who maintained a full Ottoman cultural elite household, invested significantly in the Muslim landscape of Cairo. Last but not least, one should not forget that the Ottoman sultan’s firman was the legal basis of the pashas’ rule.

There was also an invisible Ottoman underworld in Egypt. Sufis orders, especially in Cairo, had spiritual and material significance in Istanbul. Musicians and entertainers travelled between the two rich centers and other cities. Religious endowments (sing. waqf) in Cairo were related to Istanbul in many ways, going back to the sixteenth century. Religious scholars often received a salary from the sultan or from the Sheikh-ül-Islam. Small merchant networks fully functioned between Egypt, the Syrian provinces, and Tunis. Shari‘a court cases from Cairo could sometimes even reach the Istanbul courts. The question of religious endowments in Egypt belonging to individuals in republican Turkey remained a complex problem until the 1950s. Merchants living in Istanbul and in other parts of the empire had significant investments in Cairo and vice versa. Likewise, criminals circulated (and sometimes escaped) between Istanbul and Cairo. Al-Qanun al-Sultani, the “Sultanic Law,” was the basis of the penal system in Egypt, though the governor wanted the right of death penalty for himself in the 1850s. Political dissidents also commuted between the two cities (scholars are yet to properly explore the use of fin-de-siècle Cairo as an Ottoman hub of anti-Abdülhamidian propaganda). The khedives and the sultans used various figures in the capitals to keep each other at bay.

The often-romanticized bourgeois society of Alexandria was in large part a semi-Ottoman society, which had its less spectacular but perhaps even more powerful sister-groups in Cairo. The ministries in Cairo received the French, Arabic, and Turkish newspapers printed in Istanbul until the 1880s. Armenian refugees arrived in Egypt in large numbers. Egyptians were legally Ottoman citizens until the First World War.  Even in the 1920s there were (Ottoman) Turkish newspapers printed in Cairo.

Citadel of Cairo, between 1870 and 1890, by Antonio Beato, Library of Congress.

The British occupation did not reduce the Istanbul-Cairo traffic. Egypt and its capital Cairo remained both a cultural and financial market for Ottomans—from the Ottoman musical theater brought by enterprising Turkish-speaking Armenians, to clothing and other products.  Indeed, the occupation arguably boosted the symbolic Ottoman presence by the arrival of an Ottoman Imperial High Commissioner (the war hero Muhtar Pasha) in Cairo in 1885. Ottoman flags symbolized Egypt’s belonging and resistance in the 1890s. Some argue this was a mere instrumentalization of the Ottoman Empire because Egyptian anti-colonial mass nationalism had already bloomed, clamoring for an independent nation-state.

The urban nature of these dynamics and relations cannot be overemphasized. Rural Egyptians rarely identified with the empire. Outside the cities, “the Turks” meant taxation, conscription in the army, misuse of power, and pashas and beys with legal privileges. Until the nineteenth century, peasants could apply for justice to the distant sultan as his subjects by way of petitions, but the Mehmed Ali family, by assuming legislative powers, blocked this unique means of connection between the poorest and the highest.

The provincial system of the late Ottoman Empire was torn between centralization, local concerns, and integration into global infrastructures, as Johann Büssow, Christoph Herzog, On Barak, Toufoul Abou-Hodeib, and Till Grallert have recently shown on the examples of Ottoman Palestine, Iraq, Egypt, Lebanon and Syria, respectively. It was up to local elite activity to shape whether the processes of urbanization and capitalism were to be paired with imperial initiatives as negotiations played out in the European imperial context.

Kathryn Watterson on I Hear My People Singing

WattersonIn I Hear My People Singing: Voices of African-American Princeton, Kathryn ‘Kitsi’ Watterson illuminates the resilience and ingenuity of the historic black neighborhood, just outside the gates of Princeton University, through the words of its residents. Watterson recently answered some questions from writer Kristin Cashioli, providing insight into this extraordinary labor of love that began nearly two decades ago.

What does this project mean to you?  Why is it so special?

KW: Wow, that question gave me goosebumps. When this book began, it was a simple effort to collect the life stories of the elders in the Witherspoon neighborhood.  This was thrilling work, and was second nature to me as a writer and journalist. Since I was a child, I’ve seen African Americans as national heroes. Imagine yourself living in the heat of laws and efforts to thwart you, keep you in poverty, to punish, demean, and often kill you; imagine that every single day, you encounter negative stereotypes because of the shade of your skin or the shape of your nose. Racism and segregation are so cruel and invasive, and it’s just amazing how black people live with some form of violence against them at all times. Even though Princeton wasn’t as bad as many places, it still had these patterns. Most white people never experience something so crushing on a daily basis. To see the great strength that dealt with this assault, rose above it, and created from within it, makes this project special. The humanity in these residents’ lives, the richness of their vision, and the way they came together made working on this project an honor. Turning this project into a book as a way to preserve these vital stories has been a gift to me.

What sets your book apart from others about race and justice issues?

KW: It’s the speakers’ voices that make this so powerful and intimate. There is such a panorama of diverse, complex individuals and their experiences. They are the heart of the book. I’ve been told that historians have done a lot of writing about racial issues in the North during the 18th and 19th centuries, but that this book will add to the scholarship of northern segregation in the 20th century. This is not a traditional oral history–it is its own creation, one that’s highly accessible and allows readers to imagine the inside experience as if they’d been there themselves.

What aspects of your research most inspired and surprised you?

KW: I was most surprised to discover the continuity of prejudice that this community has dealt with and addressed nonstop for more than three and a half centuries.  Its origins began with slavery, long before the village of Prince Town or the university existed. The designs of racism were established when slavery was an accepted practice, and have continued in other forms through America’s and the neighborhood’s history. In my research, I felt I kept uncovering the deep roots of racism. To see something that disrupts families and the lives of children so blatantly encouraged and accepted by fellow human beings is unnerving.  It’s very similar to the way we accept the prison system today. We act like it’s normal.

The most inspirational parts of this research were definitely the stories of individuals who blossomed throughout their lives in their service to others. I fell in love with Rev. William Robeson (Paul Robeson’s father) who, after escaping from slavery, went to Lincoln University, studied Greek, Latin, and Hebrew, earned two degrees in Theology, and then moved seamlessly into his ministerial leadership and family life in Princeton. His wisdom and grace are extraordinary. I also was enthralled by Betsy Stockton, formerly enslaved as well, who started schools in the 1830s for a people who had been forbidden to learn how to read or write. She founded the Witherspoon School for Colored Children and engaged the entire community in growing a school system that deeply understood the importance of education.

What do you hope your readers will take away from your book?

KW: So often in my own urban neighborhood, I see young black men crossing the street or walking with their heads down so as to deflect the fear they have learned to expect from white people passing by who clutch their bags or glance away. I especially want white readers to understand the impact of this diminishment and to recognize why black lives matter—just as it’s taken for granted that white lives do. I want to open readers’ minds, let them in on another level, and allow them to know how it feels. I want them to realize the courage it takes for an individual to live with hope and with the belief that the human experience we share is sacred.

How did you arrive at the title?

KW: Paul Robeson, the great orator, singer, and social justice advocate, wrote, “I heard my people singing,” when he was describing the beloved Witherspoon neighborhood where he was born. Back when we were conducting interviews in 2000, one of my students, Lauren Miller, suggested it as the title. One of the things we did during that time was to hold several public presentations at the library, the community center, and the university. Students read excerpts from the interviews we had, and residents in the audience heard their own words spoken back to them. It was like hearing singing—all of these different voices blending together. It was exhilarating and was exactly what I wanted people to hear—this fantastic chorus of voices. For me, in their stories, I hear America singing. I hear what this country could be. I feel lifted up, and I think everyone who has been involved with this book feels the same.

What is the greatest thing you have learned from writing this book?

KW: That magic happens. It all started with Hank Pannell’s love for the community and his urgency about saving these unique stories. When he told me that what he and his other Witherspoon neighbors really wanted was an oral history, I thought, how could I possibly do this? What seemed like an impossibility became a reality because it was built on love. I got swept up by the beautiful spirit of this neighborhood, and so did my students. It was contagious. This book shows what can happen when people come together, caring for and honoring one another.

What has been the greatest compliment and toughest criticism given to you as an author?  How have these helped you?

KW: The greatest compliments I’ve been given as an author are from people who’ve told me after reading one of my books, “This changed my life.” It’s been a moment or an emotional connection or a story that opened up the world for them somehow and moved them to new insights and a deeper understanding of our human experience. I’m humbled by this, as well as encouraged, because I, too, have been transformed by doing this work.

The toughest criticism that stands out is when someone wise tells me I’ve gotten something wrong, missed a point, or missed the bigger picture. These incidents act as a vehicle for learning. They sharpen my thinking and help me immensely with revisions. For this book, critical feedback that I received from three historians opened up my perspective and helped me discover more about the centuries of segregation and slavery in the North.

What is your next project?

KW: Before I found out that Princeton University Press wanted to publish I Hear My People Singing, I was immersed in a novel about a Philadelphia-based newspaper reporter at odds with the police in the 1970s. I’m eager to get back to work on it, as well as on several short stories that are treading water, waiting to get to the shore.

Kathryn ‘Kitsi’ Watterson is an award-winning journalist and writer, as well as a beloved teacher of writing. The author of nine books, including Women in Prison, Not by the Sword, You Must Be Dreaming, and Growing Into Love, she’s drawn to issues of justice and to expressing the full range of human experience. Her creative writing classes at the University of Pennsylvania, as they were at Princeton, are known for their close sense of community and personal empowerment, engagement with the world, and a great deal of fun and laughter. In addition, she sings, drums and plays percussion with an improvisational band, The Unity. She lives in the City of Philadelphia.

 

Alexander Todorov on the science of first impressions

TodorovWe make up our minds about others after seeing their faces for a fraction of a second—and these snap judgments predict all kinds of important decisions. For example, politicians who simply look more competent are more likely to win elections. Yet the character judgments we make from faces are as inaccurate as they are irresistible; in most situations, we would guess more accurately if we ignored faces. So why do we put so much stock in these widely shared impressions? What is their purpose if they are completely unreliable? In Face Value, Alexander Todorov, one of the world’s leading researchers on the subject, answers these questions as he tells the story of the modern science of first impressions. Here he responds to a few questions about his new book.

What inspired you to write this book?

AT: I have been doing research on how people perceive faces for more than 10 years. Typically, we think of face perception as recognizing identity and emotional expressions, but we do much more than that. When we meet someone new, we immediately evaluate their face and these evaluations shape our decisions. This is what we informally call first impressions. First impressions pervade everyday life and often have detrimental consequences. Research on first impressions from facial appearance has been quite active during the last decade and we have made substantive progress in understanding these impressions. My book is about the nature of first impressions, why we cannot help but form impressions, and why these impressions will not disappear from our lives.

In your book, you argue that first impressions from facial appearance are irresistible. What is the evidence?

AT: As I mentioned, the study of first impressions has been a particularly active area of research and the findings have been quite surprising. First, we form impressions after seeing a face for less than one-tenth of a second. We decide not only whether the person is attractive but also whether he or she is trustworthy, competent, extroverted, or dominant. Second, we agree on these impressions and this agreement emerges early in development. Children, just like adults, are prone to using face stereotypes. Third, these impressions are consequential. Unlucky people who appear “untrustworthy” are more likely to get harsher legal punishments. Those who appear “trustworthy” are more likely to get loans on better financial terms. Politicians who appear more “competent” are more likely to get elected. Military personnel who appear more “dominant” are more likely to achieve higher ranks. My book documents both the effortless nature of first impressions and their biasing effects on decisions.

The first part of your book is about the appeal of physiognomy—the pseudoscience of reading character from faces. Has not physiognomy been thoroughly discredited?

AT: Yes and no. Most people today don’t believe in the great physiognomy myth that we can read the character of others from their faces, but the evidence suggests that we are all naïve physiognomists: forming instantaneous impressions and acting on these impressions. Moreover, fueled by recent research advances in visualizing the content of first impressions, physiognomy appears in many modern disguises: from research papers claiming that we can discern the political, religious, and sexual orientations of others from images of their faces to private ventures promising to profile people based on images of their faces and offering business services to companies and governments. This is nothing new. The early 20th century physiognomists, who called themselves “character analysts,” were involved in many business ventures. The modern physiognomists are relying on empirical and computer science methods to legitimize their claims. But as I try to make clear in the book, the modern claims are as far-stretched as the claims of the old physiognomists. First, different images of the same person can lead to completely different impressions. Second, often our decisions are more accurate if we completely ignore face information and rely on common knowledge.

You mentioned research advances that visualize the content of first impressions. What do you mean?

AT: Faces are incredibly complex stimuli and we are inquisitively sensitive to minor variations in facial appearance. This makes the study of face perception both fascinating and difficult. In the last 10 years, we have developed methods that capture the variations in facial appearance that lead to specific impressions such as trustworthiness. The best way to illustrate the methods is by providing visual images, because it is impossible to describe all these variations in verbal terms. Accordingly, the book is richly illustrated. Here is a pair of faces that have been extremely exaggerated to show the variations in appearance that shape our impressions of trustworthiness.

Faces

Most people immediately see the face on the left as untrustworthy and the face on the right as trustworthy. But notice the large number of differences between the two faces: shape, color, texture, individual features, placement of individual features, and so on. Yet we can easily identify global characteristics that differentiate these faces. Positive expressions and feminine appearance make a face appear more trustworthy. In contrast, negative expressions and masculine appearance make a face appear less trustworthy. We can and have built models of many other impressions such as dominance, extroversion, competence, threat, and criminality. These models identify the contents of our facial stereotypes.

To the extent that we share face stereotypes that emerge early in development, isn’t it possible that these stereotypes are grounded in our evolutionary past and, hence, have a kernel of truth?

AT: On the evolutionary scale, physiognomy has a very short history. If you imagine the evolution of humankind compressed within 24 hours, we have lived in small groups during the entire 24 hours except for the last 5 minutes. In such groups, there is abundant information about others coming from first-hand experiences (like observations of behavior and interactions) and from second-hand experiences (like testimonies of family, friends, and acquaintances). That is for most of human history, people did not have to rely on appearance information to infer the character of others. These inferences were based on much more reliable and easily accessible information. The emergence of large societies in the last few minutes of the day changed all that. The physiognomists’ promise was that we could handle the uncertainty of living with strangers by knowing them from their faces. It is no coincidence that the peaks of popularity of physiognomists’ ideas were during times of great migration. Unfortunately, the physiognomists’ promise is as appealing today as it was in the past.

Are there ways to minimize the effects of first impressions on our decisions?

AT: We need to structure decisions so that we have access to valid information and minimize the access to appearance information. A good real life example is the increase of the number of women in prestigious philharmonic orchestras. Until recently, these orchestras were almost exclusively populated by men. What made the difference was the introduction of blind auditions. The judges could hear the candidates’ performance but their judgments could not be swayed by appearance, because they could not see the candidates.

So why are faces important?

AT: Faces play an extremely important role in our mental life, though not the role the physiognomists imagined. Newborns with virtually no visual experience prefer to look at faces than at other objects. After all, without caregivers we will not survive. In the first few months of life, faces are one of the most looked upon objects. This intensive experience with faces develops into an intricate network of brain regions dedicated to the processing of faces. This network supports our extraordinary face skills: recognizing others and detecting changes in their emotional and mental states. There are likely evolutionary adaptations in the human face—our bare skin, elongated eyes with white sclera, and prominent eyebrows—but these adaptations are about facilitating the reading of other minds, about communicating and coordinating our actions, not about inferring character.

Jack Zipes on The Sorcerer’s Apprentice

The Sorcerer’s ApprenticeZipes by Jack Zipes enlightens and entertains with enduring, spellbinding tales of sorcery. The title might conjure up images of Mickey Mouse from the Disney film Fantasia, or of Harry Potter. But as this anthology reveals, “sorcerer’s apprentice” tales—in which a young person rebels against, or complies with, an authority who holds the keys to magical powers—have been told through the centuries, in many languages and cultures, from classical times to today. This unique and beautifully illustrated book brings together more than fifty sorcerer’s apprentice stories by a plethora of writers, including Ovid, Sir Walter Scott, and the Brothers Grimm. Zipes recently took the time to answer a few questions about his latest book.

What prompted you to collect all the different “The Sorcerer’s Apprentice” tales?

JZ: We are still living in the Dark Ages, and consequently, five years ago, I wanted to shed some light on what Theodor Adorno and Max Horkheimer have called the dialectic of the Enlightenment, and why reason has been obfuscated and overshadowed by superstition, religion, government, and corporate powers in so-called modern “enlightened” times. At one point in my research I came across various versions of “The Sorcerer’s Apprentice” that contradicted the popular Disney tale with which I was most familiar. These were stories in which the apprentice defeated a sordid, power-hungry sorcerer and which showed how knowledge could be used for emancipation and enlightenment. From that point on, I could not stop collecting similar tales that are included in the present anthology.

Why are these tales so significant?

JZ: The “Sorcerer’s Apprentice” tales are highly significant because they present magic primarily as a stable value of transformation that allows for self-consciousness and self-fashioning. These unusual tales counter the defamation of magic by religion, science, and the state, and raise the question of the master/slave dialectic that challenges elites and the status quo. In this regard, I have framed this anthology of “Sorcerer’s Apprentice” tales to represent the two major strains of “The Sorcerer’s Apprentice” tradition and their historical development. It begins with tales of “The Humiliated Apprentice,” followed by “The Rebellious Apprentice” stories and Krabat tales. The majority of the tales stem from “The Rebellious Apprentice” tale type. This larger number, compared to the smaller amount of “The Humiliated Apprentice” tale type, is not due to my prejudices but simply to the fact that I did not find as many “Humiliated Apprentice” tales in my vast research as I did “Rebellious Apprentice” tales. The disparity speaks for itself, for the rebellion of apprentices of all kinds is a constant in all societies and in all ages.

What is at the basis of the conflict between the sorcerer and his apprentice?

JZ: Our knowledge of ourselves and the world is attained through experiencing “slavery” and knowing what being in slavery entails. This means that we are all involved in what the philosopher Georg Wilhelm Friedrich Hegel, in Phenomenology of Spirit, calls a dialectical bloody battle to death that underlies all types of “Sorcerer’s Apprentice” tales. In most of the oral tales and many of the literary tales about sorcerer’s apprentices, the narrative perspective is what I call the “slave’s perspective,” a voice and view from below, no matter who the collector, mediator, or publisher of the tale may have been. This view is what makes the tales so striking. Though it may be difficult to explore and explain how people, defined and treated as slaves, contributed to the formation of culture from below, it can be done. The renowned American folklorist Richard Dorson drew important historical connections in his collection Negro Folktales in Michigan in dealing with American master/slave tales told by African-Americans. The“Sorcerer’s Apprentice” tales do not provide a solution to the master/slave conflict; they are not prescriptions or formulas for ending this conflict. What I have tried to demonstrate through collecting tales from various periods, and from different European, Asian, African, and American countries, is how these stories play out essential conflicts whose resolutions determine the nature of what it is to be human and humane.

Why do magic and magical transformation matter so much in people’s lives?

JZ: For a variety of reasons throughout the centuries, people have sought knowledge and power through magic. Tales about the desire for magic, which have evolved from words, fragments, and sentences, are not only wish-fulfillment tales but also blunt expressions of emotions that reveal what the people who tell, write, and listen to the tales lack, and what they want. Most people in the world believe in some kind of magic, whether religious or secular, and want to control “magic,” or “mana,” to escape enslavement and determine the path of their lives. According to the French sociologist Pierre Bourdieu, all people are stamped by what he calls our habitus—the beliefs, values and customs that mark and shape our thoughts, values, and behavior from birth. To know ourselves and to free ourselves, Bourdieu writes, we must continually confront masters, who, if they do not learn from their slaves, will ultimately have to die in order for the slaves to gain release and freedom.

In what way did Walt Disney warp the tradition of the rebellious apprentice?

JZ: People tend to believe that the ideal, if not definitive, version of “The Sorcerer’s Apprentice” is the Disney cinematic and literary tale produced as part of the film Fantasia in 1940. This is a misconception, and our unquestioning acceptance of the Disney version, which reinforces notions of humiliation, has ramifications for the abusive way we treat children. In fact, the transformation of the ancient “Humiliated Apprentice” tales into a “charming” children’s tale is one of the ways in which mass-mediated and commodified children’s literature ideologically warps if not perverts folklore to induct children into authoritarian civilizing processes. On the other hand, the oral traditions of anonymous storytelling that favor the “Rebellious Apprentice” tales oppose the oppression of commodified tales. Stories, storytellers, and writers look for the most fitting and artistic modality they can find to articulate views about life and the world. In the formation of what I call a memetic tradition of folk-tale types and fairy tales, there has always been a communal expression of themes that formed tales relevant to be remembered. Many of the themes are connected to beliefs in magic and magical transformation. Indeed, the pursuit of magic often underlies the patterns of folk and fairy tales. In this regard, the themes found in the “Sorcerer’s Apprentice” tales are organically connected with the customs and beliefs of people who engendered them, and they form never-ending cultural traditions of resistance to the domination of magicians who misuse power. This unique collection of “Sorcerer’s Apprentice” tales sheds light on how young people have rebelled against the oppression and domination of magicians who use magic to control and exploit apprentices. The long history of the“Sorcerer’s Apprentice” tales that date back to Greco-Roman times reflects how rebellion is key to understanding the relevance of the tales which expose the contradictions in the popularity of the Disney commodified version.

The exhibits of Frank Lloyd Wright

SmithWright organized the majority of more than one hundred exhibitions of his work that were mounted between 1894 and his death in 1959, viewing them as crucial to his self-presentation as his extensive writings. Wright on Exhibit presents the first history of this neglected aspect of the architect’s influential career. Drawing extensively from Wright’s unpublished correspondence, Kathryn Smith shows that he was an artist-architect projecting an avant-garde program, an innovator who expanded the palette of installation design as technology evolved, and a social activist driven to revolutionize society through design. Placing Wright’s exhibitions side by side with his writings, Smith shows how integral these exhibitions were to his vision and sheds light on the broader discourse concerning architecture and modernism during the first half of the twentieth century. Wright on Exhibit features color renderings, photos, and plans—check some of them out here:

Andrew Lo on Adaptive Markets: Financial Evolution at the Speed of Thought

Half of all Americans have money in the stock market, yet economists can’t agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe. In this groundbreaking book, Andrew Lo cuts through this debate with a new framework, the Adaptive Markets Hypothesis, in which rationality and irrationality coexist. Adaptive Markets shows that the theory of market efficiency isn’t wrong but merely incomplete. Lo’s new paradigm explains how financial evolution shapes behavior and markets at the speed of thought. An ambitious new answer to fundamental questions in economics, Adaptive Markets is essential reading for anyone who wants to know how markets really work. We asked him to explain the Adaptive Markets Hypothesis, the strengths and limitations on the current theories, and how this new thinking can be practically applied.

What led you to write this book?

AL: Ever since I was a graduate student in economics, I’ve been struggling with the uncomfortable observation that economic theory doesn’t seem to work in practice. As elegant as this theory is, there are so many examples where the data just don’t support the theory that, after a while, I started wondering just how useful our theories were. For example, stock market prices don’t follow random walks, market prices don’t always seem rational, and people often make poor decisions, especially when it comes to financial matters. But it takes a theory to beat a theory. Rather than just criticizing existing theories, I decided to develop an alternative—this book describes the personal journey I took to arrive at that alternative, which I call the Adaptive Markets Hypothesis.

What’s the Adaptive Markets Hypothesis?

AL: The Adaptive Markets Hypothesis is my solution to the longstanding debate in financial economics between two competing camps. One camp consists of the disciples of the Efficient Markets Hypothesis, who believe that investors are rational decision makers and market prices fully reflect all available information. The opposing camp consists of the psychologists and behavioral economists who believe that investors are irrational and market prices are driven by “animal spirits.” It turns out that both camps have correctly captured certain aspects of human behavior, but neither camp offers a complete picture of how investors and markets behave. The Adaptive Markets Hypothesis fills this gap.

How?

AL: By drawing on recent research in psychology, neuroscience, evolutionary biology, and artificial intelligence, I show that human behavior is the result of several different components of the brain, some of which produce rational behavior while others produce more instinctive emotional behavior. These components often work together, but occasionally they compete with each other. And for obvious evolutionary reasons, rationality can be trumped by emotion and instinct when we’re confronted with extreme circumstances like physical threats—we “freak out.” The problem is that these hardwired responses to physical threats are also triggered by financial threats, and freaking out is generally not the best way to deal with such threats. Therefore, investors and markets have a split personality: sometimes they’re quite rational but every so often, they freak out.

Are you suggesting that the Efficient Markets Hypothesis, which dominates financial thinking today, is wrong?

AL: No! On the contrary, the Efficient Markets Hypothesis is one of the most useful, powerful, and beautiful pieces of economic reasoning that economists have ever proposed. Generations of investors and portfolio managers have been saved from bad investment decisions because of the Efficient Markets Hypothesis, which says that if something seems too good to be true, it probably is. The Efficient Markets Hypothesis is not wrong; it’s merely incomplete. Its focus is the behavior of investors and markets in normal business environments, where the “wisdom of crowds” rules the day. What’s missing is the “madness of mobs,” when investors are reacting emotionally and instinctively in response to extreme business environments—good or bad—leading either to irrational exuberance or panic selling. The Adaptive Markets Hypothesis provides a more complete framework in which both types of behaviors are possible. The combination of these behaviors yields a much richer set of implications for price dynamics, investment strategies, risk management, and financial regulation.

Who is the intended audience for this book?

AL: My intention was to write this book for the general reader, but only time will tell whether or not I’ve succeeded. In fact, I’m hoping that there’s something for everyone in this book. For example, readers wondering whether or not it’s possible to beat the stock market using mathematical models will want to read Chapter 2, “If You’re So Smart, Why Aren’t You Rich?” For readers already convinced that it’s possible and want to understand the neuroscientific basis of irrational behavior, they’ll want to read Chapter 3, “If You’re So Rich, Why Aren’t You Smart?” No book on finance would be complete without a discussion of how the recent financial crisis could have happened to us—a country with one of the most sophisticated financial systems in the world—and that’s Chapter 9, “Fear, Greed, and Financial Crisis.” And for readers interested in getting a glimpse of the future of the financial industry and the amazing things that can be accomplished with finance if used properly, there’s Chapter 12, “To Boldly Go Where No Financier Has Gone Before.” Although the book is based on my academic research, I’ve worked hard to translate “academic-speak” into plain English, using simple analogies and real-life examples to make the research come alive. In fact, there’s not a single equation or mathematical formula in the book, which is no easy feat for someone from MIT!

In Adaptive Markets you take an interdisciplinary view of financial markets, bringing in cognitive neuroscience, biology, computer science, and engineering. How did you come to bring all of these seemingly disparate fields together and why is that important?

AL: Although I do enjoy learning new things and have broad-ranging interests, when I started my academic career as a financial economist, I had no interest or intention in doing “interdisciplinary” research. I was perfectly happy spending my days and nights working on traditional neoclassical financial economics—portfolio theory, derivatives pricing models, asset pricing models, financial econometrics, and so on. But the more I tried to fit financial theories to data, the more frustrated I became that these theories performed so poorly. So I started trying to understand why the theories broke down and how they could be fixed. I began by studying behavioral economics and finance, which led me to psychology, which then to the cognitive neurosciences, and so on. I was dragged—sometimes kicking and screaming—from one field of study to the next in my quest to understand why financial markets don’t work the way we think (and want them to). This process ultimately led me to the Adaptive Markets Hypothesis, which is a very satisfying (for me, at least) integration of various disciplines that have something to say about human behavior. I’m especially pleased by the fact that Adaptive Markets reconciles the two competing schools of thought in financial economics, both of which are compelling in their own right even though they’re incomplete.

Why do we need to understand the evolution of finance?

AL: Many authors and academics will use evolution as a metaphor when referring to the impact of change. In Adaptive Markets, I use evolution quite literally because financial markets and institutions are nothing short of evolutionary adaptations that Homo sapiens has developed to improve our chances of survival. Therefore, if we really want to understand how the financial system works, how it changes over time and circumstances, and what we can do to improve it, we need to understand the evolution of finance. And unlike animal species, which evolve from one generation to the next, the financial system evolves at the speed of thought.

You argue that economics wishes it were more like the hard science of physics where 99% of all observable phenomena can be explained with three laws. Will we ever have a complete understanding of how financial markets function?

AL: It’s true that most economists—myself included—suffer from a psychological disorder called “physics envy.” We wish we could explain 99% of economic behavior with three laws like the physicists but this is a pipe dream. The great physicist Richard Feynman put it best when he said, “Imagine how much harder physics would be if electrons had feelings!” I tell all my students at the start of the semester that all economic theories are approximations to a much more complex reality, so the key question for investors and portfolio managers is not “is the theory correct?” but rather, “how good is the approximation?” The answer to this question lies largely in the environment, which plays a huge role in evolutionary theories. Whether we’ll ever be able to develop a truly complete theory of human behavior—and, therefore, how financial markets function—is hard to say. But I do believe that we can get much closer to that complete theory through the Adaptive Markets Hypothesis.

How can investors and portfolio managers incorporate the Adaptive Markets Hypothesis into their investment philosophies?

AL: The Adaptive Markets Hypothesis has a relatively straightforward but sweeping implication for all investment philosophies, and that has to do with change. During normal business environments, the principles of Efficient Markets are an excellent approximation to reality. For example, from the 1930s to the early 2000s, a period where the U.S. stock market had relatively consistent average returns and volatility, a long-only passive investment strategy of 60% stocks and 40% bonds produced pretty decent returns, particularly for those who were investing over a 10- or 20-year horizon. The problem is that this approach doesn’t always work. When market conditions change and we experience large macro shocks like the financial crisis of 2008, then simple heuristics like 60/40 no longer work as well because financial markets have changed in their dynamics. Today’s markets are now much more responsive to intervention by governments and their central banks and punctuated by the irregular cycle of fear and greed. So since 2007 and 2008, we’ve seen a very different market dynamic than over the previous six decades. The point of Adaptive Markets is not simply to be wedded to any static theory, but rather to understand how the nature of markets can change. And once it does change, we need to change with it. John Maynard Keynes put it best when, in responding to criticism that he flip-flopped on the gold standard, he said, “When the facts change, sir, I change my mind. What do you do?”

Can you give an example of how change might impact today’s investors?

AL: One important implication of Adaptive Markets for investors and portfolio managers is that passive investing is changing and we have to adapt. John Bogle—the founder of the Vanguard Group and the father of passive investing and index funds—had an incredibly important insight in the 1970s which he calls the “Cost Matters Hypothesis:” reducing trading costs can have a huge impact on wealth accumulation. Bogle has done more for the individual investor than anyone else I can think of; he democratized the investment process. Thanks to technological innovations like automated trading, electronic market-making, and big data analytics, we’re ready to take the next evolutionary step that builds on Bogle’s legacy. For example, like the trend in healthcare towards personalized medicine, we can now create personalized indexes that are passive portfolios designed to achieve specific goals for a given individual. You might be more risk tolerant than your neighbor so your portfolio will have more equities, but because you work in the financial industry and she works in big pharma, your personalized portfolio will have fewer financial stocks and hers will have fewer biopharma stocks. Also, personalized indexes can manage the risk more actively to suit an individual’s threshold of “pain.” Current financial wisdom criticizes investors who don’t invest for the long run, and I’ve always thought such criticism to be terribly unfair. After all, how easy is it for someone to stick with an investment that’s lost 50% of its value over just a few months? Well, that’s exactly what happened between the fourth quarter of 2008 and the first quarter of 2009. Traditional investment advice is a bit like trying to prevent teenage pregnancies by asking teenagers to abstain—it’s not bad advice, but it’s unrealistic. Why not manage the risk of an individual’s portfolio more actively so as to reduce the chances of freaking out?

Finance has developed a bad reputation in the popular press, particularly in the aftermath of the recent financial crisis. Does the Adaptive Markets Hypothesis have anything to say about this and how things can be improved?

AL: Absolutely. At the heart of all bad behavior, regardless of the industry or context, is human nature. Humans are the Curious George of the animal kingdom, but there’s no “man in the yellow hat” to bail us out when we get into trouble. Homo sapiens has evolved in some remarkable ways and we’re capable of extraordinary things, both good and bad. The same social and cultural forces that give rise to wonderful organizations like the Peace Corps, the Red Cross, and Doctors without Borders can sometimes lead to much darker and destructive organizations. The only way for us to deal more effectively with the negative aspects of society is to acknowledge this dual nature of human behavior. Chapter 11 of Adaptive Markets, titled “Fixing Finance,” is devoted entirely to this objective. We have to be careful not to throw out the baby with the bathwater—the financial system definitely can be improved, but we shouldn’t vilify this critically important industry because of a few bad actors.

What are some specific proposals for how to fix finance?

AL: Well, before we can fix finance, we need to understand where financial crises come from, and the Adaptive Markets Hypothesis has a clear answer: crises are the product of human behavior coupled with free enterprise. If you can eliminate one or both of these two components, you can eliminate financial crises. Otherwise, financial crises are an avoidable fact of modern life. Human misbehavior is a force of Nature, not unlike hurricanes, flash floods, or earthquakes, and it’s not possible to legislate away these natural disasters. But this doesn’t mean we can do anything about it—we may not be able to prevent hurricanes from occurring, but we can do a great deal to prepare for them and reduce the damage they do. We can do a lot to prepare for financial crises and reduce the damage they do to those individuals and institutions least able to withstand their devastating consequences. This perspective is important because it goes against the traditional narrative that financial crises are caused by a few greedy unscrupulous financiers and once we put them in jail, we’ve taken care of the problem. The Adaptive Markets perspective suggests something different: the problem is us. Specific proposals for dealing with crises include: using new technologies in data science to measure economic activity and construct early warning indicators of impending crises; studying crises systematically like the way the National Transportation Safety Board studies airplane crashes so we know how to make the financial system safer; creating adaptive regulations that change with the environment, becoming more restrictive during booms and less restrictive during busts; and systematically measuring individual behavior and corporate culture quantitatively so we can engage in “behavioral risk management.”

Now that you’ve written this book, where do you see your research going from here?

AL: Well, this is still early days for the Adaptive Markets Hypothesis. There’s so much left to be done in exploring the implications of the theory and testing the implications empirically and experimentally whenever possible. The Efficient Markets Hypothesis took decades and hundreds of academic studies to get established, and the same will be true of this one. One of my goals in writing this book is to motivate my academic and industry colleagues to start this vetting process. In the same way that Darwin’s theory of evolution had to be tested and challenged from many different perspectives, the Adaptive Markets Hypothesis has to go through the gauntlet of academic scrutiny. One important implication of the Adaptive Markets perspective is that we need to change the way we collect data and test theories in financial economics. For example, traditional tests of financial theories involve collecting stock market prices and analyzing the statistical properties of their risks and returns. Contrast this approach with how an ecologist would study a newly discovered tropical island in an effort to preserve it. He would begin by first cataloguing the flora and fauna, identifying the key species, and measuring their biomasses and behaviors. Next, he would determine the food chain, environmental threats, and predator/prey relationships, and then turn to population dynamics in the context of the changing environment. Ultimately, such a process would lead to a much deeper understanding of the entire ecosystem, allowing ecologists to determine the best way to ensure the long-term health and sustainability of that island. Imagine doing the same thing with the financial industry. We would begin by cataloguing the different types of financial institutions and investors, measuring their financial biomass, and identifying key species—banks, hedge funds, pension funds, retail investors, regulators, etc.—and their behaviors. Then we would determine the various types of business relationships and interdependencies among these species, which are critical for mapping the population dynamics of this financial ecosystem. This approach seems sensible enough, but it’s not yet being done today (except by my collaborators and me!).

How do you continue to evolve your own thinking? What do you do?

AL: Someone very wise once said that the beginning of wisdom is humility, and I’m convinced that this is how we make progress as a civilization. Once we’re convinced that we have all the answers, we stop asking new questions and learning. So I’m continually looking for new ways to understand financial market behavior, and constantly humbled by how little I know compared to how much we have yet to discover. In this respect, I guess I’m an intellectual opportunist—I don’t care where an idea comes from or what academic discipline it belongs to; if it gives me new insight into an existing problem, I’ll use it and build on it. I’m currently working on several applications of the Adaptive Markets Hypothesis to investments, risk management, and financial regulation, and also hoping to test the theory in the context of individual and institutional investment decisions. The initial results are quite promising and show that financial industry participants adapt much more quickly than we thought. These results point to several important unintended consequences that have clear implications for how we should regulate the industry so as to reduce the chances of another financial crisis.
