With this profound final work, completed in the days leading up to his death, Michel Serres presents a vivid picture of his thinking about religion-a constant preoccupation since childhood-thereby completing Le Grand Recit, the comprehensive explanation of the world and of humanity to which he devoted the last twenty years of his life. Themes from Serres's earlier writings-energy and information, the role of the media in modern society, the anthropological function of sacrifice, the role of scientific knowledge, the problem of evil-are reinterpreted here in the light of the Old Testament accounts of Isaac and Jonah and a variety of Gospel episodes, including the Three Wise Men of the Epiphany, the Transfiguration, Peter's denying Christ, the Crucifixion, Emmaus, and the Pentecost. Monotheistic religion, Serres argues, resembles mathematical abstraction in its dazzling power to bring together the real and the virtual, the natural and the transcendent; but only in its Christian embodiment is it capable of binding together human beings in such a way that partisan attachments are dissolved and a new era of history, free for once of the lethal repetition of collective violence, can be entered into.

A Financial Times Best Book of the Year A hardheaded book that confronts and outlines possible solutions to a seemingly intractable problem: that helping the poor often hurts the environment, and vice versa. Can we fight poverty and inequality while protecting the environment? The challenges are obvious. To rise out of poverty is to consume more resources, almost by definition. And many measures to combat pollution lead to job losses and higher prices that mainly hurt the poor. In Unsustainable Inequalities, economist Lucas Chancel confronts these difficulties head-on, arguing that the goals of social justice and a greener world can be compatible, but that progress requires substantial changes in public policy. Chancel begins by reviewing the problems. Human actions have put the natural world under unprecedented pressure. The poor are least to blame but suffer the most—forced to live with pollutants that the polluters themselves pay to avoid. But Chancel shows that policy pioneers worldwide are charting a way forward. Building on their success, governments and other large-scale organizations must start by doing much more simply to measure and map environmental inequalities. We need to break down the walls between traditional social policy and environmental protection—making sure, for example, that the poor benefit most from carbon taxes. And we need much better coordination between the center, where policies are set, and local authorities on the front lines of deprivation and contamination. A rare work that combines the quantitative skills of an economist with the argumentative rigor of a philosopher, Unsustainable Inequalities shows that there is still hope for solving even seemingly intractable social problems.

The possibility of a nuclear war that could destroy civilization has influenced the course of international affairs since 1945, suspended like a sword of Damocles above the heads of the world's leaders. The fact that we have escaped a third world war involving strategic nuclear weapons—indeed, that no atomic weapon of limited power has yet been used under battlefield conditions—seems nothing short of a miracle. Revisiting debates on the effectiveness and ethics of nuclear deterrence, Jean-Pierre Dupuy is led to reformulate some of the most difficult questions in philosophy. He develops a counterintuitive but powerful theory of apocalyptic prophecy: once a major catastrophe appears to be possible, one must assume that it will in fact occur. Dupuy shows that the contradictions and paradoxes riddling discussions of deterrence arise from the tension between two opposite conceptions of time: one in which the future depends on decisions and strategy, and another in which every occurring event is one that could not have failed to occur. Considering the immense destructive power of nuclear warheads and the almost unimaginable ruin they are bound to cause, Dupuy reaches a provocative conclusion: whether they bring about good or evil does not depend on the present or future intentions of those who are in a position to use them. The mere possession of nuclear weapons is a moral abomination.

How Robespierre's career and legacy embody the dangerous contradictions of democracy Maximilien Robespierre (1758-1794) is arguably the most controversial and contradictory figure of the French Revolution, inspiring passionate debate like no other protagonist of those dramatic and violent events. The fervor of those who defend Robespierre the "Incorruptible," who championed the rights of the people, is met with revulsion by those who condemn him as the bloodthirsty tyrant who sent people to the guillotine. Marcel Gauchet argues that he was both, embodying the glorious achievement of liberty as well as the excesses that culminated in the Terror. In much the same way that 1789 and 1793 symbolize the two opposing faces of the French Revolution, Robespierre's contradictions were the contradictions of the revolution itself. Robespierre was its purest incarnation, neither the defender of liberty who fell victim to the corrupting influence of power nor the tyrant who betrayed the principles of the revolution. Gauchet shows how Robespierre's personal transition from opposition to governance was itself an expression of the tragedy inherent in a revolution whose own prophetic ideals were impossible to implement. This panoramic book tells the story of how the man most associated with the founding of modern French democracy was also the first tyrant of that democracy, and it offers vital lessons for all democracies about the perpetual danger of tyranny.

An internationally renowned chemist, popular television personality, and bestselling author, Herv? This heads the first laboratory devoted to molecular gastronomy--the scientific exploration of cooking and eating. By testing recipes that have guided cooks for centuries, and the various dictums and maxims on which they depend, Herv? This unites the head with the hand in order to defend and transform culinary practice.

With this new book, Herv? This's scientific project enters an exciting new phase. Considering the preparation of six bistro favorites--hard-boiled egg with mayonnaise, simple consomm?, leg of lamb with green beans, steak with French fries, lemon meringue pie, and chocolate mousse--he isolates the exact chemical properties that tickle our senses and stimulate our appetites. More important, he connects the mind and the stomach, identifying methods of culinary construction that appeal to our memories, intelligence, and creativity. By showing that the creation of a meal is as satisfying as its consumption, Herve This recalibrates the balance between food and our imaginations. The result is a revolutionary perspective that will tempt even the most casual cooks to greater flights of experimentation.

The Allied landings on the coast of Normandy on June 6, 1944, have assumed legendary status in the annals of World War II. But in overly romanticizing D-day, Olivier Wieviorka argues, we have lost sight of the full picture. "Normandy" offers a balanced, complete account that reveals the successes and weaknesses of the titanic enterprise.

In addition to describing the landings with precision and drama, Wieviorka covers the planning and diplomatic background, Allied relationships, German defensive preparations, morale of the armies, economics and logistics, political and military leaders, and civilians and soldiers experience of the fighting. Surprisingly, the landing itself was not the slaughter the general staff expected. The greater battle for Normandy waged on farmland whose infamous hedgerows, the bocage, created formidable obstacles took a severe toll not only in lives lost, but on the survivors who experienced this grueling ordeal.

D-day, Wieviorka notes, was a striking accomplishment, but it was war, violent and cruel. Errors, desertions, rivalries, psychological trauma, self-serving motives, thefts, and rapes were all part of the story. Rather than diminishing the Allied achievement, this candid book underscores the price of victory and acknowledges the British, American, and Canadian soldiers who dashed onto the Normandy beaches not as demigods, but as young men.

Living with Robots recounts a foundational shift in the field of robotics, from artificial intelligence to artificial empathy, and foreshadows an inflection point in human evolution. Today's robots engage with human beings in socially meaningful ways, as therapists, trainers, mediators, caregivers, and companions. Social robotics is grounded in artificial intelligence, but the field's most probing questions explore the nature of the very real human emotions that social robots are designed to emulate. Social roboticists conduct their inquiries out of necessity-every robot they design incorporates and tests a number of hypotheses about human relationships. Paul Dumouchel and Luisa Damiano show that as roboticists become adept at programming artificial empathy into their creations, they are abandoning the conventional conception of human emotions as discrete, private, internal experiences. Rather, they are reconceiving emotions as a continuum between two actors who coordinate their affective behavior in real time. Rethinking the role of sociability in emotion has also led the field of social robotics to interrogate a number of human ethical assumptions, and to formulate a crucial political insight: there are simply no universal human characteristics for social robots to emulate. What we have instead is a plurality of actors, human and nonhuman, in noninterchangeable relationships. As Living with Robots shows, for social robots to be effective, they must be attentive to human uniqueness and exercise a degree of social autonomy. More than mere automatons, they must become social actors, capable of modifying the rules that govern their interplay with humans.

"Note-by-Note Cooking" is a landmark in the annals of gastronomy, liberating cooks from the constraints of traditional ingredients and methods through the use of pure molecular compounds. 1-Octen-3-ol, which has a scent of wild mushrooms; limonene, a colorless liquid hydrocarbon that has the smell of citrus; sotolon, whose fragrance at high concentrations resembles curry and at low concentrations, maple syrup or sugar; tyrosine, an odorless but flavorful amino acid present in cheese -- these and many other substances, some occurring in nature, some synthesized in the laboratory -- make it possible to create novel tastes and flavors in the same way that elementary sound waves can be combined to create new sounds.

Note-by-note cooking promises to add unadulterated nutritional value to dishes of all kinds, actually improving upon the health benefits of so-called natural foods. Cooking with molecular compounds will be far more energy efficient and environmentally sustainable than traditional techniques of cooking. This new way of thinking about food heralds a phase of culinary evolution on which the long-term survival of a growing human population depends. Herv? This clearly explains the properties of naturally occurring and synthesized compounds, dispels a host of misconceptions about the place of chemistry in cooking, and shows why note-by-note cooking is an obvious -- and inevitable -- extension of his earlier pioneering work in molecular gastronomy. An appendix contains a representative selection of recipes, vividly illustrated in color.

An engaging look at the founder of one of the most important philosophical schools of ancient Greece. The ancient philosopher Diogenes—nicknamed "The Dog" and decried by Plato as a "Socrates gone mad"—was widely praised and idealized as much as he was mocked and vilified. A favorite subject of sculptors and painters since the Renaissance, his notoriety is equally due to his infamously eccentric behavior, scorn of conventions, and biting aphorisms, and to the role he played in the creation of the Cynic school, which flourished from the 4th century B.C. to the Christian era. In this book, Jean-Manuel Roubineau paints a new portrait of an atypical philosopher whose life left an indelible mark on the Western collective imagination and whose philosophy courses through various schools of thought well beyond antiquity. Roubineau sifts through the many legends and apocryphal stories that surround the life of Diogenes. Was he, the son of a banker, a counterfeiter in his hometown of Sinope? Did he really meet Alexander the Great? Was he truly an apologist for incest, patricide, and anthropophagy? And how did he actually die? To answer these questions, Roubineau retraces the known facts of Diogenes' existence. Beyond the rehashed clichés, this book inspires us to rediscover Diogenes' philosophical legacy—whether it be the challenge to the established order, the detachment from materialism, the choice of a return to nature, or the formulation of a cosmopolitan ideal strongly rooted in the belief that virtue is better revealed in action than in theory.

The "world of letters" has always seemed a matter more of metaphor than of global reality. In this book, Pascale Casanova shows us the state of world literature behind the stylistic refinements--a world of letters relatively independent from economic and political realms, and in which language systems, aesthetic orders, and genres struggle for dominance. Rejecting facile talk of globalization, with its suggestion of a happy literary "melting pot," Casanova exposes an emerging regime of inequality in the world of letters, where minor languages and literatures are subject to the invisible but implacable violence of their dominant counterparts.

Inspired by the writings of Fernand Braudel and Pierre Bourdieu, this ambitious book develops the first systematic model for understanding the production, circulation, and valuing of literature worldwide. Casanova proposes a baseline from which we might measure the newness and modernity of the world of letters--the literary equivalent of the meridian at Greenwich. She argues for the importance of literary capital and its role in giving value and legitimacy to nations in their incessant struggle for international power. Within her overarching theory, Casanova locates three main periods in the genesis of world literature--Latin, French, and German--and closely examines three towering figures in the world republic of letters--Kafka, Joyce, and Faulkner. Her work provides a rich and surprising view of the political struggles of our modern world--one framed by sites of publication, circulation, translation, and efforts at literary annexation.

With more than two hundred entries by leading intellectuals in the French- and English-speaking world, this new volume presents the authoritative guide to twentieth-century French thought. Unrivaled in its scope and depth, "The Columbia History of Twentieth-Century French Thought" covers and critiques the intellectual figures, movements, and publications that helped shape and define fields as diverse as history and historiography, psychoanalysis, film, literary theory, cognitive and life sciences, literary criticism, philosophy, and economics. The contributors also discuss developments in French thought on such subjects as pacifism, fashion, gastronomy, technology, and urbanism.

More than just a reference volume, "The Columbia History of Twentieth-Century French Thought" offers original and imaginative explorations of a variety of topics. Contributors include prominent French thinkers, many of whom have played an integral role in the development of French thought, and American, British, and Canadian scholars who have been vital in the dissemination of French ideas. The book brings together such pairings as Etienne Balibar on Althusser; Jean Baudrillard on the futures of theory; Judith Butler on Hegel in France; R?gis Debray on mediology; Julia Kristeva on Proust; Michael Morange on the life sciences; Paul Ricoeur on ethics; Elisabeth Roudinesco on psychoanalysis; and Roger Shattuck on humanisms.

The book is divided into four parts: Movements and Currents (including all the major schools of thought, such as the Annales, deconstruction, Gaullism, n?gritude, the New Right, psychoanalysis, and structuralism); Themes (ideas that helped define intellectual work in the twentieth century, such as anti-Semitism, the avant-garde, everyday life, film theory, and nationalism); Intellectuals (including critical accounts of the lives and work of such figures as Aron, Barthes, de Beauvoir, Deleuze, Derrida, Foucault, Irigaray, Kristeva, Levinas, and Proust); and Dissemination (covering influential journals, television shows, radio programs, and newspapers).

This timely and original study transforms our understanding of the relationship between art and economics Bearing witness to the changing economic landscape amid the Cold War, artists in the 1960s created works that critiqued, reshaped, and sometimes reinforced the spirit of capitalism. At a time when currency and finance were becoming ever more abstracted-and the art market increasingly an arena for speculation-artists on both sides of the Atlantic turned to economic themes, often grounded in a human context. The Artist as Economist examines artists who approached these issues in critical, imaginative, and humorous ways: Andy Warhol and Larry Rivers incorporated the iconography of printed currency into their paintings, while Ray Johnson sought to disrupt and reinvent circuits of commerce with his mail art collages. Yves Klein and Edward Kienholz critiqued conceptions of artistic and monetary value, as Lee Lozano and Dennis Oppenheim engaged directly with the New York Stock Exchange. Such examples, which author Sophie Cras insightfully situates within their historic economic context, reveal capitalism's visual dimension. As art and economics grow more entangled, this volume offers a timely consideration of art's capacity to reflect on and reimagine economic systems.

A passionate account of how the gulf between France's metropolitan elites and its working classes are tearing the country apart Christophe Guilluy, a French geographer, makes the case that France has become an "American society"-one that is both increasingly multicultural and increasingly unequal. The divide between the global economy's winners and losers in today's France has replaced the old left-right split, leaving many on "the periphery." As Guilluy shows, there is no unified French economy, and those cut off from the country's new economic citadels suffer disproportionately on both economic and social fronts. In Guilluy's analysis, the lip service paid to the idea of an "open society" in France is a smoke screen meant to hide the emergence of a closed society, walled off for the benefit of the upper classes. The ruling classes in France are reaching a dangerous stage, he argues; without the stability of a growing economy, the hope for those excluded from growth is extinguished, undermining the legitimacy of a multicultural nation.

A revelatory account of early Islam's great diversity by the world's leading scholar of early Qur'anic manuscripts "There is no one better placed than Francois Deroche to write the history-and tell the story-of how the Quran went from words uttered by Muhammad to inviolable canonical scripture. This is a meticulous, lucid, and fascinating book."-Shawkat Toorawa, Yale University According to Muslim dogma, the recited and written text of the Qur'an as we know it today scrupulously reflects the divine word as it was originally sent down to Muhammad. An examination of early Islamic sources, including accounts of prophetic sayings, all of them compared with the oldest Qur'anic manuscripts, reveal that plurality was in fact the outstanding characteristic of the genesis and transmission of the Qur'an, both textually and orally. By piecing together information about alternative wordings eliminated from the canonical version that gradually came to be imposed during the first centuries of Islam, Francois Deroche shows that the Qur'an long remained open to textual diversity. Not only did the faithful initially adopt a flexible attitude toward the Qur'anic text, an attitude strikingly at odds with the absolute literalism later enforced by Muslim orthodoxy, but Muhammad himself turns out to have been more concerned with the meaning than the letter of the divine message.

Few would disagree that Western democracies are experiencing a crisis of representation. In the United States, gerrymandering and concentrated political geographies have placed the Congress and state legislatures in a stranglehold that is often at odds with public opinion. Campaign financing ensures that only the affluent have voice in legislation. Europeans, meanwhile, increasingly see the European Union as an anti-democratic body whose "diktats" have no basis in popular rule. The response, however, has not been an effective pursuit of better representation. In Good Government, Pierre Rosanvallon examines the long history of the alternative to which the public has gravitated: the empowered executive. Rosanvallon argues that, faced with everyday ineptitude in governance, people become attracted to strong leaders and bold executive action. If these fail, they too often want even stronger personal leadership. Whereas nineteenth-century liberals and reformers longed for parliamentary sovereignty, nowadays few contest the "imperial presidency." Rosanvallon traces this history from the Weimar Republic to Charles De Gaulle's "exceptional" presidency to the Bush-Cheney concentration of executive power. Europeans rebelling against the technocratic EU and Americans fed up with the "administrative state" have turned to charismatic figures, from Donald Trump to Viktor Orban, who tout personal strength as their greatest asset. This is not just a right-wing phenomenon, though, as liberal contentment with Obama's drone war demonstrates. Rosanvallon makes clear that contemporary "presidentialism" may reflect the particular concerns of the moment, but its many precursors demonstrate that democracy has always struggled with tension between popular government and concentrated authority.

We have long thought of the Renaissance as a luminous era that marked a decisive break with the past, but the idea of the Renaissance as a distinct period arose only during the nineteenth century. Though the view of the Middle Ages as a dark age of unreason has softened somewhat, we still locate the advent of modern rationality in the Italian thought and culture of the fifteenth and sixteenth centuries. Jacques Le Goff pleads for a strikingly different view. In this, his last book, he argues persuasively that many of the innovations we associate with the Renaissance have medieval roots, and that many of the most deplorable aspects of medieval society continued to flourish during the Renaissance. We should instead view Western civilization as undergoing several "renaissances" following the fall of Rome, over the course of a long Middle Ages that lasted until the mid-eighteenth century. While it is indeed necessary to divide history into periods, Le Goff maintains, the meaningful continuities of human development only become clear when historians adopt a long perspective. Genuine revolutions-the shifts that signal the end of one period and the beginning of the next-are much rarer than we think.

Manichaeism, once the state religion of Persia and long a vigorous contender for converts throughout the ancient Near East, is best remembered for the simplicity of its teachings about divine power. For Manicheans, the universe was ruled by a Lord of Light and a Lord of Darkness, who fought continuously for supremacy. All that was good was a gift from the Lord of Light, and all that was evil was an affliction visited by the Lord of Darkness. This dualism extended to cosmogony and ethics, splitting the universe into a spiritual realm that acted on the goodness of the human soul and a material realm that abetted the evil of the human body. These stark oppositions mask a remarkable degree of doctrinal and liturgical complexity, the details of which have been obscured by centuries of suppression and persecution, first by the Christian church, then by Islam.

One of the world's foremost experts on ancient religions, Michel Tardieu examines the fragmentary sources that have come down to us, pieces together the life and teachings of the prophet Mani (the itinerant Persian preacher and founder of this long lost faith), illuminates Manichaeism's ecclesiastical hierarchy and distinctive moral code, and investigates its ideas about the pre-life and afterlife. "Manichaeism" provides a brilliantly compact survey of what was once one of the world's great faiths, and then became one of its great heresies, surviving now only as a shadowy presence haunting the religions that superseded it.

In this wide-ranging book, one of the boldest thinkers in modern neuroscience confronts an ancient philosophical problem: can we know the world as it really is?

Drawing on provocative new findings about the psychophysiology of perception and judgment in both human and nonhuman primates, and also on the cultural history of science, Jean-Pierre Changeux makes a powerful case for the reality of scientific progress and argues that it forms the basis for a coherent and universal theory of human rights. On this view, belief in objective knowledge is not a mere ideological slogan or a naive confusion; it is a characteristic feature of human cognition throughout evolution, and the scientific method its most sophisticated embodiment. Seeking to reconcile science and humanism, Changeux holds that the capacity to recognize truths that are independent of subjective personal experience constitutes the foundation of a human civil society.
