How do scientists reason when they posit unobservables to explain their observed results? For example, how did Watson and Crick reason that DNA had a double-helix structure when they observed Franklin’s image 51, or how did Hodgkin and Huxley reason that sodium ions carried the current flowing into the membrane of a voltage-clamped giant squid axon? In Compositional Abduction and Scientific Interpretation: A granular approach (Cambridge University Press), Kenneth Aizawa argues for an account of such reasoning as singular compositional abduction: explaining particular experimental results in terms of lower-level entities, such as the bonds between nucleotides or the positive charges of sodium ions. Aizawa, who is professor of philosophy at Rutgers University—Newark, draws on close examination of scientific practice to argue that dominant views in philosophy of science regarding abduction do not capture what scientists are actually doing. Instead, he articulates compositional abduction as a specific form of inferential practice in science distinct from eliminating alternative hypotheses, employing hypothetical-deductive confirmation, or identifying mechanism components.

What does it mean to see oneself as free? And how can this freedom be attained in times of conflict and social upheaval? In this ambitious study, Moritz Föllmer explores what twentieth-century Europeans understood by individual freedom and how they endeavoured to achieve it. Combining cultural, social, and political history, this book highlights the tension between ordinary people's efforts to secure personal independence and the ambitious attempts of thinkers and activists to embed notions of freedom in political and cultural agendas. The quest to be a free individual was multi-faceted; no single concept predominated. Men and women articulated and pursued it against the backdrop of two world wars, the expanding power of the state, the constraints of working life, pre-established moral norms, the growing influence of America, and uncertain futures of colonial rule. But although claims to individual freedom could be steered and stymied, they could not, ultimately, be suppressed. Moritz Föllmer is Associate Professor of Modern History at the University of Amsterdam. He is particularly interested in Weimar and Nazi Germany, and in concepts of individuality and urbanity in twentieth-century Europe. Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand. His research interests are Cultural Studies; Critical Theory; Environmental History; Medieval (Intellectual) History; Gothic Studies; 18th and 19th Century British Literature. YouTube channel. Twitter.

New Orleans is an indispensable element of America's national identity. As one of the most fabled cities in the world, it figures in countless novels, short stories, poems, plays, and films, as well as in popular lore and song. T. R. Johnson's book New Orleans: A Writer's City (Cambridge UP, 2023) provides detailed discussions of all of the most significant writing that this city has ever inspired - from its origins in a flood-prone swamp to the rise of a creole culture at the edges of the European empires; from its emergence as a cosmopolitan, hemispheric crossroads and a primary hub of the slave trade to the days when, in its red light district, the children and grandchildren of the enslaved conjured a new kind of music that became America's greatest gift to the world; from the mid-twentieth-century masterpieces by William Faulkner, Tennessee Williams and Walker Percy to the realms of folklore, hip hop, vampire fiction, and the Asian and Latin American archives.

Dejan Djokić's book A Concise History of Serbia (Cambridge UP, 2023) covers the full span of Serbia's history – from the sixth-century Slav migrations through until the present day – in an effort to understand the country’s position at the crossroads of east and west. The book traces key developments surrounding the medieval and modern polities associated with Serbs, offering fresh interpretations and revealing a fascinating history of entanglements and communication between southeastern and wider Europe, which often had global implications. In structuring his inquiry around several recurring themes including migration, shifting borders, and the fate of small nations, Djokic challenges some of the prevailing stereotypes about Serbia and reveals the vitality of Serbian identity through the centuries.Dejan Djokić is Professor of Modern and Contemporary History and Founding Director of the Centre for the Study of the Balkans at Goldsmiths College, University of London. In June 2023, he will join the National University of Ireland, Maynooth, as Professor of History. Djokic’s research brings together three main strands of inquiry: the Yugoslav war; the global and cultural history of the Cold War; and the history of Southeastern Europe since the Middle Ages. His publications include Nikola Pašić and Ante Trumbić: The Kingdom of Serbs, Croats and Slovenes (2010) and Elusive Compromise: A History of Interwar Yugoslavia (2007), as well as contributions to numerous edited volumes, including New Perspectives on Yugoslavia: Key Issues and Controversies (2011).Iva Glisic is a historian and art historian specialising in modern Russia and the Balkans.

In this recent monograph Sarcasm in Paul's Letters (Cambridge University Press 2023, Matthew Pawlak offers the first treatment of sarcasm in New Testament studies. He provides an extensive analysis of sarcastic passages across the undisputed letters of Paul, showing where Paul is sarcastic, and how his sarcasm affects our understanding of his rhetoric and relationships with the Early Christian congregations in Galatia, Rome, and Corinth. Pawlak's identification of sarcasm is supported by a dataset of 400 examples drawn from a broad range of ancient texts, including major case studies on Septuagint Job, the prophets, and Lucian of Samosata. These data enable the determination of the typical linguistic signals of sarcasm in ancient Greek, as well as its rhetorical functions. Pawlak also addresses several ongoing discussions in Pauline scholarship. His volume advances our understanding of the abrupt opening of Galatians, diatribe and Paul's hypothetical interlocutor in Romans, the 'Corinthian slogans' of First Corinthians, and the 'fool's speech' found within Second Corinthians 10-13.

Trials of Sovereignty: Mercy, Violence, and the Making of Criminal Law in British India, 1857-1922 (Cambridge UP, 2024) offers the first legal history of mercy and discretion in nineteenth and twentieth-century India. Through a study of large-scale amnesties, the prerogative powers of pardon, executive commutation, and judicial sentencing practices, Alastair McClure argues that discretion represented a vital facet of colonial rule. In a bloody penal order, officials and judges consistently offered reduced sentences and pardons for select subjects, encouraging others to approach state institutions and confer the colonial state with greater legitimacy. Mercy was always a contested expression of sovereign power that risked exposing colonial weakness. This vulnerability was gradually recognized by colonial subjects who deployed a range of legal and political strategies to interrogate state power and question the lofty promises of British colonial justice. By the early twentieth century, the decision to break the law and reject imperial overtures of mercy had developed into a crucial expression of anticolonial politics..Alastair McClure is Assistant Professor in the Department of History at the University of Hong Kong. .Saumya Dadoo is a Ph.D Candidate at MESAAS, Columbia University.

During the mid-1930s, Germans opposed to Adolf Hitler had only a limited range of options available to them for resisting the Nazi regime. One of the most creative and successful challengers in this effort was Ernst Fraenkel, who as an attorney sought to use the law as a means of opposing Nazi oppression. In Legal Sabotage: Ernst Fraenkel in Hitler’s Germany (Cambridge University Press, 2020), Douglas G. Morris describes the ways in which Frankel stood up to the Nazis and what understandings he drew from that experience. As a veteran of the First World War, Fraenkel survived the initial purge resulting from the implementation of measures designed to bar Jews from practicing law in the Third Reich. Though his legal practice suffered, Fraenkel persisted in defending people prosecuted by the Nazis, and enjoyed success in a number of cases. While the increased restrictions and growing reach of the police state ultimately forced Fraenkel to emigrate in 1938, his experiences as a lawyer played a major role in the development of the “dual state” theory of dictatorship, the only analysis of totalitarianism written from within Nazi Germany and the cornerstone of Fraenkel’s contributions to the field of political science.

In the early 1960s, British colonial administrations in East Africa organized the systematic destruction and removal of secret documents from colonies approaching independence. The Colonial Office in London arranged the deposit of these documents in high security facilities, where they remained inaccessible until 2011 following a compensation suit by Kenyan survivors of British colonial rule against the Foreign and Commonwealth Office. Curating the Colonial Past: The ‘Migrated Archives' and the Struggle for Kenya's History (Cambridge University Press, 2025) presents the first full length exploration of these 'migrated archives', chronicling the struggle between British attempts to conceal and Kenyan efforts to reveal evidence of the colonial past. Neither displayed nor destroyed, Dr. Riley Linebaugh explores how these records formed an archival limbo in which the British government delayed moral and legal judgement of empire. Yet, these practices did not go unchallenged. Dr. Linebaugh demonstrates how disputes over the 'migrated archives' facilitated the continuation of anticolonial sovereignty struggles beyond independence, struggles which persist into the present. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars. You can find Miranda’s interviews on New Books with Miranda Melcher, wherever you get your podcasts.

It is often assumed that only sovereign states can join the United Nations. But this was not always the case. At the founding of the United Nations, a loophole drafted by British statesmen in its predecessor organisation, the League of Nations, was carried forward, allowing colonies to accede as member-states. Colonies such as India, Ireland, Egypt, and many more were afforded a tokenistic representation at the League in Geneva during the interwar years, decades before their independence. Thomas Gidney’s An International Anomaly unites three geographically distinct case studies to demonstrate the evolution of Britain's policy from a range of different viewpoints, exploring how this policy came into being, and why it was only exploited by the British Empire. He argues that this membership shaped colonial norms around sovereignty and international recognition in the interwar period and to the present day.

The outbreak of the First World War shattered the established European art market. Amidst fighting, looting, confiscations, expropriation fears and political and economic upheaval, an integrated marketplace shaped by upper-class patrons broke down entirely. In its place, Maddalena Alvi argues, can be found the origins of a recognizably modern market of nationalized spheres driven by capitalist investment and speculation, yet open to wider social strata. Delving into auction records, memoirs, newspaper articles, financial and legal documents in six languages, Alvi explores these cultural and socio-economic developments across the British, French, and German markets, as well as trade spheres such as Russia and Scandinavia. 1914 marked the end of the European art market and cemented the connection between art and finance.  The European Art Market and the First World War: Art, Capital, and the Decline of the Collecting Class, 1910–1925 (Cambridge University Press, 2025) Maddalena Alvi holds a PhD in History from the University of Cambridge, an MSc in Economic and Social History from the University of Oxford, and an MLitt in Art History from the University of Glasgow.
