Peter Godfrey-Smith, Professor of History and Philosophy of Science at the University of Sydney, explores the evolutionary roots of consciousness by surveying animal evolution and the emergence of felt experience in several lineages. He examines two central philosophical questions: how such experience might arise gradually, existing in partial forms, and whether it represents a single unified feature with variations or instead a cluster of distinct traits. Author of "Darwinian Populations and Natural Selection," and "Living on Earth: Forests, Corals, Consciousness and the Making of the World," Godfrey-Smith brings his expertise in philosophy of biology and mind to illuminate how consciousness may have emerged and why its origins remain a profound puzzle.

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.

Political theorist Annabel Brett of Cambridge University explores how the concept of “moral possibility” shapes law, politics, and public obligation. She explains that laws must be realistic for people to follow—what is morally possible varies by individual, culture, time, and circumstance. Drawing on early modern Catholic legal theory, Brett discusses how extreme demands (like enduring war or plague) may justify higher expectations, but only temporarily. She examines how colonial Spanish officials misused this framework to justify forced labor in Peru, wrongly claiming it aligned with indigenous customs. Brett contrasts this with more democratic approaches to law, like Domingo de Soto’s defense of beggars’ rights, which take individuals’ real conditions seriously. Ultimately, she shows how moral possibility is deeply tied to time, virtue, and justice. Commentary is provided by David Dyzenhaus of the University of Toronto.

It's time for a new narrative for the ocean, one that reflects current scientific knowledge and acknowledges innovative new partnerships and solutions that center the ocean in our future. In this program, Jane Lubchenco, Professor of Marine Biology at Oregon State University and with expertise in the ocean, climate change, and interactions between the environment and human well-being, talks about the two current dominant narratives for the ocean are anchored in the past. The older one considers the ocean to be so vast, bountiful, and resilient that it is simply too big to fail. This first narrative drives pollution and over-exploitation of resources. A second, more recent narrative is that the ocean is now so depleted, polluted, and disrupted, and the drivers of those outcomes are so powerful and complex, that the ocean is simply too big to fix. A third, new narrative is emerging, based on scientific findings, existing solutions, and innovative partnerships and policies. This new narrative acknowledges that the ocean is central to a safe, clean, healthy, just, and prosperous future. This new narrative tells us that the ocean is neither too big to fail, nor is it too big to fix. But it is too important and too central to our future to ignore.

Three major global challenges – climate change, loss of biodiversity and its benefits, and inequality and inequity among people – are typically tackled within three separate silos. However, scientific knowledge tells us that the three are inextricably linked. If the problems are not considered together, solutions to one may undermine solutions to the others. Moreover, more holistic, integrated solutions can deliver multiple co-benefits. Success requires integrated solutions. Jane Lubchenco, Professor of Marine Biology at Oregon State University, talks about the historically ambitious, innovative policies implemented by the Biden-Harris Administration to achieve this integration. Lubchenco is a marine ecologist with expertise in the ocean, climate change, and interactions between the environment and human well-being. From 2021-2025, she served as Deputy Director for Climate and Environment in the White House Office of Science and Technology Policy.

There's a powerful idea in the history of European legal and political thought: that laws must be possible for people to follow. Annabel Brett, professor of Political Thought and History at Cambridge University, describes how from ancient times through the Renaissance, thinkers believed that demanding the impossible—whether physically or psychologically—was a hallmark of tyranny. A classic example is Pharaoh in the Book of Exodus, who ordered the Israelites to make bricks without straw. Brett analyzes how legal thinkers balanced the need for law to be both realistic and aspirational, and how these ideas shaped the development of modern legal systems. Brett is joined by Princeton University's Melissa Lane for commentary. Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Humanities] [Show ID: 40429]

The "energy transition" is actually a shift from relying on fossil fuels (like coal, oil, and gas) to using metals to generate energy. However, extracting metals has always been a significant environmental and political issue, especially for cities. This problem has been around for centuries, even ancient Roman writers wrote about it. In this program, Helen Thompson, Professor of Political Economy at Cambridge University, talks about the historic use of fossil fuels and its economic, social and environmental impacts to the transition today to extracting metals for energy, dominated by China. Thompson points out that extracting resources will always have environmental and social costs. To mitigate these risks, she says we need to find ways to reduce international competition and ecological damage. This requires acknowledging that the idea of endless progress, which was fueled by fossil fuels, has its limits. And she says we must prioritize sustainability and responsible resource management to create a better future. Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Business] [Show ID: 40428]

Historian and political commentator Heather Cox Richardson joins UC Berkeley professor of law and history Dylan Penningroth in a timely conversation about the reshaping of the United States’ two major political parties. A professor of 19th century American history at Boston College, Richardson provides an incisive perspective on current politics to the more than three million readers of her nightly newsletter, Letters from an American. She has written for the Washington Post, the New York Times, and the Guardian, and is the author, most recently, of the best-selling book "Democracy Awakening: Notes on the State of America." Penningroth is the author of the award-winning "Before the Movement: The Hidden History of Black Civil Rights." Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Show ID: 40424]

We are at a critical moment in our society. While we advance efforts to mitigate and adapt to the climate crisis, across the globe, millions are experiencing issues of energy affordability, reliability and equitable access to modern energy technologies. In this program, Tony Reames, Professor of Environmental Justice at the University of Michigan School for Environment and Sustainability, explores the intricate intersection of energy, class, race and place, shedding light on inequities in access to and the distribution of energy resources. Reames discusses how various factors, including socio-economic conditions, policy landscapes and environmental characteristics contribute to energy inequities. The talk underscores the importance of understanding and addressing these issues in the pursuit of energy justice, emphasizing the need for inclusive scholarship, policies and funding that empower marginalized communities.
