Between Fixed and Fickle: Why Our Moral Views Keep Changing (Harvard UP, 2026), a psychologist explains why—and how—moral views change across different life stages, situations, and historical eras.

We like to believe that moral truths are obvious and unchangeable: cheating is wrong, killing is wrong, slavery is wrong. Yet people have often cheated, killed, and enslaved without regret. The acts that feel glaringly wrong to us in the here and now can seem fine to someone who is younger, or faces different circumstances, or lived a century ago.

Why does morality appear so unstable? The popular explanation is that emotions, self-interest, and social pressure easily divert people from moral concerns because they lack sincere moral commitment. But the evidence shows otherwise. Drawing on studies of young children, adolescents, and adults, Audun Dahl argues that human morality is neither immutable nor capricious, neither fixed nor fickle. Rather, people change their moral views when they believe they have good reasons to—reasons that they can articulate to themselves and would endorse for others.

The science of moral change cannot resolve our ethical dilemmas: it does not tell us what’s morally right or wrong. But it can help us understand why we have moral views in the first place, why those views keep changing, and why moral views that seem obvious to us aren’t obvious to everyone else. Separating moral psychology from moralizing, Between Fixed and Fickle reveals what’s behind our changing agreements and disagreements as we travel toward shared and hard-won moral truths.

From the beginning of the seventeenth century, French colonies and trading posts sprawled across the Atlantic and Indian Oceans. In the first pan-imperial history of the early French Empire in the English language, Mélanie Lamotte shows how an increasingly cohesive legal culture came to govern the lives of enslaved and free people of African, Malagasy, South Asian, and Native American descent. She also illuminates the important role played by these populations in the development of the empire, from Louisiana to Guadeloupe, Senegambia, Madagascar, Isle Bourbon, and India.

The early French Empire has often been portrayed as a fragmented conglomerate of isolated colonies or regions. Yet Lamotte shows that racial policies issued by the metropole, as well as by officials in the Atlantic and Indian Oceans, significantly influenced one another. Rather than focusing on the actions of administrators, however, Lamotte also reveals the extensive influence of people on the ground—especially those of non-European descent. Through their sexuality and their labor, along with their socio-economic and political endeavors, they played a critical role in building the empire and setting its limits. As they sought justice for themselves, strove to protect their kin, and aimed to improve their social conditions, these individuals also pushed against the advancement of white dominion in unexpected ways.

Archivally rich and rigorously documented, By Flesh and Toil: How Sex, Race, and Labor Shaped the Early French Empire (Harvard UP, 2026)illuminates the transoceanic connections that united the French colonial world—and recasts people of African, Malagasy, South Asian, and Native American descent as key actors in the story of empire-building.

The story of Polish Jewry, pre-Holocaust Europe’s largest Jewish community, is often told as one of creativity and contestation. In his new book, An Unchosen People: Jewish Political Reckoning in Interwar Poland, University of Chicago professor Kenneth B. Moss traces instead a complex and painful story of Polish Jewish reckoning with diasporic vulnerability, nationalism’s terrible potencies, Zionism’s promises, and the necessity of choice. Moss examines the works of Polish Jewry’s most searching thinkers as they confronted political irrationality, state crisis, and the limits of resistance. He reconstructs the desperate creativity of activists seeking to counter despair where they could not redress its causes. And he recovers a lost grassroots history of critical thought and political searching among ordinary Jews, young and powerless, as they struggled to find a viable future for themselves – in Palestine if not in Poland, individually if not communally.

Join Kenneth Moss in conversation with Stanford professor Steven Zipperstein for a discussion on this new publication and the history it unveils.
