What if Pirkei Avot has a bigger story to tell? In this episode, Rabbi Marc Katz sits down with Joseph G. Rosenstein to discuss Pirkei Avot (Ethics of the Fathers): The Big Picture (Academic Studies Press, 2026), a fresh approach to one of Judaism’s most beloved collections of rabbinic wisdom.

The 123 teachings of Pirkei Avot often seem to jump from one subject to another: Torah study, ethics, the afterlife, relationships, leadership, and the responsibilities of living a meaningful Jewish life. Rosenstein argues that beneath this seemingly disconnected collection is a larger conceptual framework. Instead of following the mishnayot in their traditional order, he groups them by theme, revealing connections that can be easy to miss when each teaching is studied on its own.

The result is a new way of seeing Pirkei Avot—not as a collection of isolated aphorisms, but as a coherent work that reflects how Judaism was reshaped in the generations following the destruction of the Temple. Rosenstein also turns the book’s ethical teachings into 90 concrete principles for living, organized into 16 themes and accompanied by kavvanot, short meditations designed to help readers put those ideas into practice.

Together, Rosenstein and Katz explore what Pirkei Avot is really trying to teach, why its teachings were assembled the way they were, and what happens when ancient rabbinic wisdom is read not simply as something to study, but as a guide for how to live.

Los Angeles in the late nineteenth century was bustling with the rise of industrialization, but the growing labor force that propelled it, mostly consisting of Mexican and Chinese men, was met with exclusion policies and deportation campaigns. Nevertheless, Chinese and Mexican women, children, and men built vibrant residential and business districts—until they were all but eradicated in the 1930s. In her compelling and textured history, Urban Borderlands: Multiracial Histories and Gendered Borders in Los Angeles, Dr. Isabela Seong Leong Quintana unearths the entwined stories of Chinatown and Sonoratown through the everyday lives of their residents.

In this conversation, we talk about the significance of comparative Latinx and Asian American Studies, the importance of spatial analysis in urban history, and the methodological challenges of locating Mexican and Chinese women and children in the archives.

Dr. Quintana is an Associate Professor of Asian American Studies at the University of California, Irvine, with affiliations in Culture & Theory and Chicané/Latiné Studies. Her work explores the interconnected histories of Asian Americans and Chicanés/Latinés, centering women and children within U.S. borderlands and recovering unarchived voices. Quintana also co-directs The Five Chinatowns Project at the Chinese Historical Society of Southern California, a community-based research initiative documenting Chinese American Los Angeles through oral histories, archival creation, and youth mentorship. She is the author of Urban Borderlands: Multiracial Histories and Gendered Borders in Los Angeles (University of North Carolina Press, 2026).

What would a postcarbon future look like? What would it take to build and maintain a more just, regenerative world? How would it feel to live—and to thrive—in that world? In Building Postcarbon Futures: Land, Justice, and Energy Transitions (Lincoln Institute of Land Policy, 2026), Billy Fleming and a wide set of contributors critically engage with the above questions and more.

Around the globe, people are transforming their social, ecological, and economic systems in response to the climate crisis. This book guides readers through 29 of these exemplary works, which span 43 nations and 6 continents. From Cuba to Kiribati, Iceland to the Andes, the prairies of North America to the expanding Gobi Desert, these case studies foreground the tactics and modes of practice being employed, often by marginalized peoples, to create more humane, hospitable places. With dispatches from more than a dozen leading scholars working on the front lines of the climate justice movement, Building Postcarbon Futures is both a celebration of action underway and a clarion call to the planners, designers, policymakers, and activists who are pushing this planet toward a future of collective flourishing.

Billy Fleming is a leading voice on the role of design in responding to the climate crisis in our cities, communities, and landscapes. He is founding codirector of the Climate and Community Institute, a progressive think tank focused on climate and political economy, and assistant professor of landscape architecture at Temple University’s Tyler School of Art and Architecture in Philadelphia.

This interview was conducted by Timi Koyejo. He is an urbanist and housing policy researcher at the Climate and Community Institute.

At its core, China in African Media: Between Influence Operations and Decolonization (Bloomsbury, 2026) is a book about power, journalism, geopolitical influence, and knowledge production in China–Africa relations. It examines how the People’s Republic of China has moved beyond simply establishing Chinese media organizations such as Xinhua and CGTN in Africa toward a much more dispersed system of engagement. Conceptualizing these engagements collectively as a multimodal or mixed-media ecology of influence, Umejei highlights China’s ability to reach African audiences directly through Chinese media, indirectly through African news organizations, institutionally through partnerships, professionally through the journalists it trains, and infrastructurally through technologies implemented by Chinese firms.

Underlying the book is a strong normative concern about the implications of this expansion of Chinese media engagement for Africa’s democracy, leadership, developmental aspirations, and decolonization. In this regard, Umejei addresses the question: Is the emerging South–South media relationship helping to decolonize African journalism by weakening Western dominance, or is China principally replacing Western influence with a new form of Chinese influence? The book draws on semi-structured interviews with journalists across fourteen African countries, content analysis, policy documents, and publicly available materials.

In John Charles Simon and Jennalee Donian’s Understanding Laughter and Humor: Why We Laugh, Why We Don’t, and Why It Matters (Palgrave Macmillan, 2025), the authors put forward a comprehensive new theoretical approach to understanding laughter and the humour we use to inspire it. Applying an evolutionary and biological lens to these complex and universal human behaviours, the book distinguishes itself from classical and contemporary theories by focusing not simply on laughter’s causes and effects, but on what can be gleaned from considering its communicative meaning.

At the centre of the book is the Mutual Vulnerability Theory (MVT) of Laughter, which understands laughter as a vital form of nonverbal communication, one that seeks in various ways to “lift” or “lower” moments of physical, emotional, cognitive, or social vulnerability between people. From this perspective, laughter sheds light on the social dynamics that govern human interaction, both positive and negative. It reveals the importance of vulnerability and status in our conscious and subconscious lives, while also underscoring our desire to cooperate, our respect for those who compete fairly, and our disdain for those who do not.

Wide-ranging and highly accessible, Understanding Laughter and Humor will be of interest to general readers, humour scholars, psychologists, anthropologists, comedians, and anyone curious about a seemingly mundane but vital aspect of everyday life — one intrinsic not only to human sociality, but also deeply connected to our great ape relatives and evolutionary past.

Additional content mentioned in the episode:

Understanding Laughter and Humor: A Companion and Guide, Volume 1, the first in a companion-guide series applying MVT to examples of humour and laughter across different media and formats.

John’s Psychology Today blog, Laughter and Humor 101, which expands on and explores various aspects of the Mutual Vulnerability Theory.
