Legal scholar Annabel Brett explores the idea of “moral possibility”—the boundary between what laws demand and what people can realistically or ethically be expected to do. Drawing from early modern thinkers like Aquinas, Suarez, and Hobbes, Brett shows how moral impossibility has long shaped debates about legal obligation, resistance, and political agency. Commentators Melissa Lane and David Dyzenhaus join the discussion, examining how this concept applies to everything from climate action and military conscription to unjust regimes and democratic norms. Together, they highlight how institutions, customs, and time shape the space between legal duty and human capacity—and why recognizing this gap is vital to both justice and legitimacy.

![“My Droplet of Fate Reflects the Jewish Ocean”: The Legacy of Béla Pásztor
In the early 20th century, Budapest was the second-largest Jewish city in Europe, and Jewish artists and intellectuals played a major role in the city’s cosmopolitan cultural life. Among them was theater and cinema director and producer Béla Pásztor, whose career was marked by early success and later oppression. In a conversation with UC San Diego history professor Deborah Hertz, Béla’s son, Rafael Pastor, explores his family’s history before, during, and after the Nazi occupation of Hungary, including his parents’ emigration to Israel, where he was born.
In commemoration of the 80th anniversary of the deportations and annihilations of Hungarian Jews in 1944, which Béla survived in hiding, the conversation is preceded by a brief historical overview and survivor testimonies of this harrowing—and unforgettable—tragedy. [Show ID: 40227]

A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=xcjgEdRJMOU
Archaeology can help communities understand environmental change, protect cultural heritage, and prepare for an uncertain climate future. Isabel C. Rivera-Collazo, Ph.D., of UC San Diego studies relationships among people, oceans, coastal ecosystems, and climate in Puerto Rico and the Caribbean. She explains how Hurricane Maria shifted her research from identifying theoretical vulnerabilities to supporting communities facing immediate risks. Her work combines archaeology with ecology, biology, geology, local histories, and community knowledge. Research on plants, fishing traditions, coral reefs, and coastal sites has supported sand dune restoration, heritage protection, and the creation of a marine protected area. Rivera-Collazo emphasizes that residents are experts on their own landscapes and should guide research priorities. Recovering knowledge from the past can strengthen identity, support ecosystem restoration, and help communities shape more resilient futures. [8/2026] [Show ID: 41490]

FAQ
Q: How can archaeology help communities prepare for climate change?
A: Archaeology reveals how people adapted to environmental changes in the past and how ecosystems and cultural practices developed over time. When combined with local knowledge, this research can support heritage protection, coastal restoration, and decisions about climate adaptation.
Q: How did Hurricane Maria change Rivera-Collazo’s research?
A: Before Hurricane Maria, much of her work on climate vulnerability was theoretical. The storm showed how political, economic, and environmental risks could combine, leading her to focus more directly on community priorities, disaster resilience, and practical applications of archaeological research.
Q: Why is community knowledge important in archaeology?
A: Archaeological sites are part of the heritage of living communities, not detached objects from the past. Rivera-Collazo emphasizes that residents understand their own landscapes and should help guide research, challenge assumptions, and determine how knowledge is used.
