    In the thirteenth-century Mediterranean, commerce transformed as merchants shifted from Roman to Indo-Arabic numerals—an alternative that better facilitated complex calculations. It has long been known that this transition stemmed from Europe’s increasing exchanges with India, Persia, and the Arabic world. Yet much remains to be understood about how Indo-Arabic numerals—and the practical arithmetic they enabled—actually spread across Europe. As Dr. Raffaele Danna shows in The Craft of Indo-Arabic Numerals: How Practical Arithmetic Shaped Commerce and Mathematics in Western Europe, 1200–1600 (Harvard University Press, 2026), it was hundreds of ordinary merchants, schoolmasters, and artisans who nurtured these changes, thereby driving key advances in both commerce and mathematics. Drawing on an original catalog of more than 1,200 practical arithmetic manuals, Dr. Danna charts the incremental spread of the new figures with unprecedented precision. While Italian merchants were the early adopters, it took nearly three centuries for Indo-Arabic numerals to become established in northern Europe. As Dr. Danna shows, adoption did not follow the routes of maritime trade. Rather, Indo-Arabic numerals moved gradually across the continent through inland networks of practitioners. Everywhere they went, the ten figures enhanced commercial practices and facilitated the emergence of a coherent language of mathematical craft. The growing social circulation of this knowledge, in turn, had a lasting impact on the economic trajectory of Western Europe. By the late sixteenth century, even academics were absorbing lessons from the vernacular tradition—a development that led to the first major breakthroughs in European mathematical theory since antiquity. Combining economic history with the social history of mathematics, The Craft of Indo-Arabic Numerals illuminates the integral role of practical arithmetic in both intellectual and commercial transformations across Western Europe. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

  • Stephen F. Jones, "The First Social Democracy: The Democratic Republic of Georgia, 1918–1921" (Harvard UP, 2026)

    Stephen F. Jones, "The First Social Democracy: The Democratic Republic of Georgia, 1918–1921" (Harvard UP, 2026)
    2026/04/21
    Following the collapse of the Russian Empire, the small nation of Georgia established its independence in May 1918. Its leaders surprised the world by creating the first social democratic state. Based on a combination of parliamentarianism and direct democracy, it was a representative government of the peasants and workers themselves, with ballots in their hands. The First Social Democracy: The Democratic Republic of Georgia, 1918–1921 (Harvard University Press, 2026) is the definitive history of a government that should inspire social democrats today. Professor Stephen F. Jones chronicles how the founders of the new state navigated myriad challenges, including territorial threats from abroad, internal ethnic conflicts, and geopolitical rivalries between the imperial Ottomans, the British, and the Germans. In the midst of these existential challenges, Georgia’s social democrats set about writing a constitution to put the country on a distinctive path of genuine self-government—protecting democratic rights, promoting political pluralism, and championing equality. Professor Jones brings to life the passionate debates that shaped Georgia’s democracy during a moment of acute global instability. The Democratic Republic of Georgia was strangled in its crib. Just four days after the constitution was ratified, the capital fell to the Red Army. Under Soviet rule, the republic was lost to history. Soviet scholars were forbidden to research this Georgian story, and Western scholars had little interest in a small and peripheral state that was independent for only three years. Recovering a forgotten experiment in democratic citizenship and statecraft, Dr. Jones reminds us of those audacious times when Georgians created and defended political freedom against the rise of Soviet communism. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

    Jim Downs’ most recent book is Maladies of Empire: How Colonialism, Slavery, and War Transformed Medicine. Professor Downs is the Gilder Lehrman-National Endowment for the Humanities Professor of Civil War Era Studies and History at Gettysburg College. The book offers a new history of epidemiology by shifting focus to the people behind the data points—people who were enslaved, imprisoned, or in some circles overlooked by conventional histories of epidemiology. The book shifts across locations and empires from the late eighteenth to the late nineteenth century because it wants to show how the confluence of war, imperialism, and slavery really made modern epidemiology. This interview was a collaborative effort among Professor Laura Stark and students at Vanderbilt University in the course, “American Medicine & the World.” Please email Laura with any feedback on the interview or questions about how to design collaborative interview projects for the classroom.

  • Rishi Rajpopat, "Panini's Perfect Rule: A Modern Solution to an Ancient Problem in Sanskrit Grammar" (Harvard UP, 2025)

    Rishi Rajpopat, "Panini's Perfect Rule: A Modern Solution to an Ancient Problem in Sanskrit Grammar" (Harvard UP, 2025)
    2026/04/09
    Panini’s Ashtadyayi is one of the most famous works in Sanskrit, a so-called “linguistic machine” that, through its 4,000 words, allows someone to generate words and grammar. Generations of commentators have tried to figure out exactly how to best interpret the work and explain its various contradictions and overlapping instructions. Then, in 2022, Rishi Rajpopat, a PhD student at Cambridge, said he’d figured out how to unravel Panini’s work to create a cohesive set of rules–and potentially wiped away centuries of commentary. The announcement made headlines (and led to some grumbling among other Sanskrit professors). That work is now a book—Panini's Perfect Rule: A Modern Solution to an Ancient Problem in Sanskrit Grammar (Harvard UP, 2025)—and Rishi joins us today to talk about it.  Rishi Rajpopat is Research Assistant Professor in the Department of Philosophy and Religious Studies at the University of Macau. His research on Pāṇini’s grammar has been covered by the BBC, Daily Mail, The Telegraph, the Times of India, The Hindu, and other global news outlets. You can find more reviews, excerpts, interviews, and essays at The Asian Review of Books, including its review of Panini’s Perfect Rule.

  • Peter Mauch, "Tojo: The Rise and Fall of Japan's Most Controversial World War II General" (Harvard UP, 2026)

    Peter Mauch, "Tojo: The Rise and Fall of Japan's Most Controversial World War II General" (Harvard UP, 2026)
    2026/03/31
    The military general who became Emperor Hirohito’s prime minister, Tojo Hideki is most often remembered as an iron-fisted leader who dragged Japan into World War II and—after spectacular losses—was eventually executed as a war criminal. Yet Tojo was far more than his ignominious end. In fact, as Dr. Peter Mauch argues in Tojo: The Rise and Fall of Japan's Most Controversial World War II General (Harvard University Press, 2026), he was one of the twentieth century’s most accomplished military statesmen. Over a career of some forty years, Tojo successfully launched himself into the highest echelons of political power. He was not only a tactical genius, Dr. Mauch shows, but also a savvy administrator, a fierce imperialist, and a deeply loyal advisor to the emperor. Tojo’s career took off with the notorious Kwantung Army in Manchuria, where he played a key role in escalating the Sino-Japanese War during the 1930s. As he rose through the ranks, becoming minister of war and then army chief of staff, he honed the efficiency of the Imperial Army and enhanced its influence within the emperor’s court. All the while, he deftly negotiated the fractious military rivalries that arose wherever he went. Brilliant, ambitious, and often ruthless, Tojo reached political heights that were perhaps matched only by his precipitous fall in the final months of World War II. Layered and evocative, Tojo is at once a riveting military history of Showa-era Japan and a nuanced portrait of the relentless personality at its center. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

  • Entrepreneurial Work Ethic

    Entrepreneurial Work Ethic
    2026/03/16
    In this episode of High Theory, Saronik talks with Erik Baker about the Entrepreneurial Work Ethic. The dominant work ethic of our current moment, it asks us to constantly create new work for ourselves. Eric contrasts the entrepreneurial work ethic with the industrious work ethic, which valued hard work and drudgery in one’s allotted task. Over the course of the 20th century industriousness was replaced by entrepreneurship in the American economic imaginary. The ultimate villain of the entrepreneurial mode is the bureaucrat, the ultimate failing is complacency. This toxic, exhausting ethos in which the standard of all labor is changing the world, paradoxically stabilizes our economic system, by trapping us in unachievable dreams. We should note that High Theory as an academic side hustle is exemplary of the entrepreneurial work ethic, even if we have no ethics. That’s why we made a Patreon. The transcript of this episode lives here as a WordDoc and here as a PDF. Erik’s new book, Make Your Own Job: How the Entrepreneurial Work Ethic Exhausted America (Harvard UP 2025) explains how this entrepreneurial work ethic took hold, from its origins in late nineteenth-century success literature to the gig economy of today, sweeping in strange bedfellows: Marcus Garvey and Henry Ford, Avon ladies and New Age hippies. Business schools and consultants exhorted managers to cultivate the entrepreneurial spirit in their subordinates, while an industry of self-help authors synthesized new ideas from psychology into a vision of work as “self-realization.” Baker argues that the entrepreneurial work ethic has given meaning to work in a world where employment is ever more precarious––and in doing so, has helped legitimize a society of mounting economic insecurity and inequality. Where work is hard to find and older nostrums about diligent effort fall flat, the advice to “make your own job” keeps hope alive. Erik Baker is a lecturer in the History of Science Department and the director of the senior thesis program for the History & Science concentration. He received his PhD from Harvard and his BA from Northwestern University. He has published on the history of social science and American capitalism in Modern Intellectual History, History of the Human Sciences, and Studies in History and Philosophy of Science. He also writes widely for magazines such as n+1, The Baffler, and The Drift, where he is an associate editor.

    Jorge Cañizares-Esguerra and Adrian Masters, "The Radical Spanish Empire: How Paperwork Politics Remade the New World" (Harvard UP, 2026)
    2026/03/13
    The Radical Spanish Empire: How Paperwork Politics Remade the New World by Jorge Cañizares-Esguerra and Adrian Masters (Harvard UP, 2026) is a groundbreaking history of political struggle in the Spanish New World, where commoners and elites alike challenged the social order through the remarkable power of paperwork. As Spanish conquistadors swept through the New World, the Crown envisioned that a rigidly hierarchical aristocratic order would flourish in their wake. At first, this vision seemed to be within reach: the great conquistadors ruled as noblemen over millions. Yet contrary to all expectations, the Spanish empire in the New World quickly became a hotbed of radical efforts to overturn the emerging order. With the conquistadors in retreat, new enclaves controlled by powerful friars and native lords arose. But they too collapsed, again to the surprise of many.

    Guoqi Xu, "The Idea of China: A Contested History" (Harvard UP, 2026)
    2026/03/08
    What counts as China, and who counts as Chinese? China became a capitalist superpower by investing in globalization. Now that it has established its credentials—and emerged as a major US competitor—its leaders are looking within, focused on suppressing dissent and fostering cohesion. The result has been an increasingly nationalist cultural agenda, celebrating a Chinese identity steeped in the mystique of the Middle Kingdom and nostalgia for heroic twentieth-century resistance. Yet Chinese nationalism, like nationalism everywhere, is fraught. Few Westerners, and even fewer Chinese, recognize that the very idea of China is up for grabs. Xu Guoqi is the founding director of the Institute of Transnational History of China at the University of Hong Kong, and author of The Idea of China: A Contested History (Harvard UP, 2026) Lucas Tse is Examination Fellow at All Souls College, Oxford.
