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.

Abraham: The First Jew (Yale UP, 2025) is the story of Abraham, the first Jew, portrayed as two lives lived by one person, paralleling the contradictions in Judaism throughout its history

In this new biography of Abraham, Judaism’s foundational figure, Anthony Julius offers an account of the origins of a fundamental struggle within Judaism between skepticism and faith, critique and affirmation, thinking for oneself and thinking under the direction of another. Julius describes Abraham’s life as two separate lives, and as a version of the collective life of the Jewish people.

Abraham’s first life is an early adulthood of questioning the polytheism of his home city of Ur Kasdim until its ruler, Nimrod, condemns him to death and he is rescued, he believes, by a miracle. In his second life, Abraham’s focus is no longer on critique but rather on conversion and on his leadership over his growing household, until God’s command that he sacrifice his son Isaac. This test, the Akedah (or “Binding”), ends with another miracle, as he believes, but as Julius argues, it is also a catastrophe for Abraham. The Akedah represents for him an unsurpassed horizon—and in Jewish life thereafter. This book focuses on Abraham as leader of the first Jewish project, Judaism, and the unresolvable, insurmountable crisis that the Akedah represents—both in his leadership and in Judaism itself.

Once upon a time, or so we’ve been told, medical ethics were confined to the patient-doctor relationship. As long as doctors were true to their Hippocratic oaths, as long as they acted with compassion and wisdom, then all expectations were met.

Life is more complicated today, and so is healthcare: an undertaking, like all others, that is influenced by social, political, legal and cultural factors.

Nothing is value-free.

In Bioethics and Biopolitics in Israel: Socio-legal, Political and Empirical Analysis (Cambridge University Press, 2019), Professor Shai Lavi and his colleagues have produced a groundbreaking work that offers a novel understanding of Israeli bioethics. It is a milestone in the comparative literature of bioethics.

Bringing together a range of experts, the book's interdisciplinary structure employs a contemporary, sociopolitical-oriented approach to bioethics issues, with an emphasis on empirical analysis, that will appeal not only to scholars of bioethics, but also to students of law, medicine, humanities, and social sciences around the world. Its focus on the development of bioethics in Israel serves as a template for cross-cultural and transcultural research into the moral, ethical, political and social aspects of bioethics.
