Uniting thirty years of authoritative scholarship by a master of textual detail, Machiavelli's Virtue is a comprehensive statement on the founder of modern politics. Harvey Mansfield reveals the role of sects in Machiavelli's politics, his advice on how to rule indirectly, and the ultimately partisan character of his project, and shows him to be the founder of such modern and diverse institutions as the impersonal state and the energetic executive. Accessible and elegant, this groundbreaking interpretation explains the puzzles and reveals the ambition of Machiavelli's thought."e;The book brings together essays that have mapped [Mansfield's] paths of reflection over the past thirty years. . . . The ground, one would think, is ancient and familiar, but Mansfield manages to draw out some understandings, or recognitions, jarringly new."e;-Hadley Arkes, New Criterion"e;Mansfield's book more than rewards the close reading it demands."e;-Colin Walters, Washington Times"e;[A] masterly new book on the Renaissance courtier, statesman and political philosopher. . . . Mansfield seeks to rescue Machiavelli from liberalism's anodyne rehabilitation."e;-Roger Kimball, The Wall Street Journal

Gabriel Tarde ranks as one of the most outstanding sociologists of nineteenth-century France, though not as well known by English readers as his peers Comte and Durkheim. This book makes available Tarde's most important work and demonstrates his continuing relevance to a new generation of students and thinkers.Tarde's landmark research and empirical analysis drew upon collective behavior, mass communications, and civic opinion as elements to be explained within the context of broader social patterns. Unlike the mass society theorists that followed in his wake, Tarde integrated his discussions of societal change at the macrosocietal and individual levels, anticipating later twentieth-century thinkers who fused the studies of mass communications and public opinion research.Terry N. Clark's introduction, considered the premier guide to Tarde's opus, accompanies this important work, reprinted here for the first time in forty years.

In this groundbreaking work, Christa Davis Acampora offers a profound rethinking of Friedrich Nietzsche's crucial notion of the agon. Analyzing an impressive array of primary and secondary sources and synthesizing decades of Nietzsche scholarship, she shows how the agon, or contest, organized core areas of Nietzsche's philosophy, providing a new appreciation of the subtleties of his notorious views about power. By focusing so intensely on this particular guiding interest, she offers an exciting, original vantage from which to view this iconic thinker: Contesting Nietzsche.?Though existence-viewed through the lens of Nietzsche's agon-is fraught with struggle, Acampora illuminates what Nietzsche recognized as the agon's generative benefits. It imbues the human experience with significance, meaning, and value. Analyzing Nietzsche's elaborations of agonism-his remarks on types of contests, qualities of contestants, and the conditions in which either may thrive or deteriorate-she demonstrates how much the agon shaped his philosophical projects and critical assessments of others. The agon led him from one set of concerns to the next, from aesthetics to metaphysics to ethics to psychology, via Homer, Socrates, Saint Paul, and Wagner. In showing how one obsession catalyzed so many diverse interests, Contesting Nietzsche sheds fundamentally new light on some of this philosopher's most difficult and paradoxical ideas.

How should we speak of bodies and soulsIn Coming to Mind, Lenn E. Goodman and D. Gregory Caramenico pick their way through the minefields of materialist reductionism to present the soul not as the brain's rival but as its partner. What acts, they argue, is what is real. The soul is not an ethereal wisp but a lively subject, emergent from the body but inadequately described in its terms.Rooted in some of the richest philosophical and intellectual traditions of Western and Eastern philosophy, psychology, literature, and the arts and the latest findings of cognitive psychology and brain science-Coming to Mind is a subtle manifesto of a new humanism and an outstanding contribution to our understanding of the human person. Drawing on new and classical understandings of perception, consciousness, memory, agency, and creativity, Goodman and Caramenico frame a convincing argument for a dynamic and integrated self capable of language, thought, discovery, caring, and love.

Today we are all familiar with the iconic pictures of the nebulae produced by the Hubble Space Telescope's digital cameras. But there was a time, before the successful application of photography to the heavens, in which scientists had to rely on handmade drawings of these mysterious phenomena.?Observing by Hand sheds entirely new light on the ways in which the production and reception of handdrawn images of the nebulae in the nineteenth century contributed to astronomical observation. Omar W. Nasim investigates hundreds of unpublished observing books and paper records from six nineteenth-century observers of the nebulae: Sir John Herschel; William Parsons, the third Earl of Rosse; William Lassell; Ebenezer Porter Mason; Ernst Wilhelm Leberecht Tempel; and George Phillips Bond. Nasim focuses on the ways in which these observers created and employed their drawings in data-driven procedures, from their choices of artistic materials and techniques to their practices and scientific observation. He examines the ways in which the act of drawing complemented the acts of seeing and knowing, as well as the ways that making pictures was connected to the production of scientific knowledge.?An impeccably researched, carefully crafted, and beautifully illustrated piece of historical work, Observing by Hand will delight historians of science, art, and the book, as well as astronomers and philosophers.

In the past two decades in the United States, more than 1,600 Catholic elementary and secondary schools have closed, and more than 4,500 charter schools-public schools that are often privately operated and freed from certain regulations-have opened, many in urban areas. With a particular emphasis on Catholic school closures, Lost Classroom, Lost Community examines the implications of these dramatic shifts in the urban educational landscape.?More than just educational institutions, Catholic schools promote the development of social capital-the social networks and mutual trust that form the foundation of safe and cohesive communities. Drawing on data from the Project on Human Development in Chicago Neighborhoods and crime reports collected at the police beat or census tract level in Chicago, Philadelphia, and Los Angeles, Margaret F. Brinig and Nicole Stelle Garnett demonstrate that the loss of Catholic schools triggers disorder, crime, and an overall decline in community cohesiveness, and suggest that new charter schools fail to fill the gaps left behind.This book shows that the closing of Catholic schools harms the very communities they were created to bring together and serve, and it will have vital implications for both education and policing policy debates.

Leo Strauss and his alleged political influence regarding the Iraq War have in recent years been the subject of significant media attention, including stories in the Wall Street Journal and New York Times.Time magazine even called him "e;one of the most influential men in American politics."e; With The Truth about Leo Strauss, Michael and Catherine Zuckert challenged the many claims and speculations about this notoriously complex thinker. Now, with Leo Strauss and the Problem of Political Philosophy, they turn their attention to a searching and more comprehensive interpretation of Strauss's thought as a whole, using the many manifestations of the "e;problem of political philosophy"e; as their touchstone.?For Strauss, political philosophy presented a "e;problem"e; to which there have been a variety of solutions proposed over the course of Western history. Strauss's work, they show, revolved around recovering-and restoring-political philosophy to its original Socratic form. Since positivism and historicism represented two intellectual currents that undermined the possibility of a Socratic political philosophy, the first part of the book is devoted to Strauss's critique of these two positions. Then, the authors explore Strauss's interpretation of the history of philosophy and both ancient and modern canonical political philosophers, including Plato, Aristotle, Machiavelli, and Locke. Strauss's often-unconventional readings of these philosophers, they argue, pointed to solutions to the problem of political philosophy. Finally, the authors examine Strauss's thought in the context of the twentieth century, when his chief interlocutors were Schmitt, Husserl, Heidegger, and Nietzsche.?The most penetrating and capacious treatment of the political philosophy of this complex and often misunderstood thinker, from his early years to his last works, Leo Strauss and the Problem of Political Philosophy reveals Strauss's writings as an attempt to show that the distinctive characteristics of ancient and modern thought derive from different modes of solving the problem of political philosophy and reveal why he considered the ancient solution both philosophically and politically superior.

Ever since Kant and Hegel, the notion of autonomy-the idea that we are beholden to no law except one we impose upon ourselves-has been considered the truest philosophical expression of human freedom. But could our commitment to autonomy, as Theodor Adorno asked, be related to the extreme evils that we have witnessed in modernityIn Autonomy after Auschwitz, Martin Shuster explores this difficult question with astonishing theoretical acumen, examining the precise ways autonomy can lead us down a path of evil and how it might be prevented from doing so.Shuster uncovers dangers in the notion of autonomy as it was originally conceived by Kant. Putting Adorno into dialogue with a range of European philosophers, notably Kant, Hegel, Horkheimer, and Habermas-as well as with a variety of contemporary Anglo-American thinkers such as Richard Rorty, Stanley Cavell, John McDowell, and Robert Pippin-he illuminates Adorno's important revisions to this fraught concept and how his different understanding of autonomous agency, fully articulated, might open up new and positive social and political possibilities. Altogether, Autonomy after Auschwitz is a meditation on modern evil and human agency, one that demonstrates the tremendous ethical stakes at the heart of philosophy.?

In his 2010 book What Is a Person?, Christian Smith argued that sociology had for too long neglected this fundamental question. Prevailing social theories, he wrote, do not adequately "e;capture our deep subjective experience as persons, crucial dimensions of the richness of our own lived lives, what thinkers in previous ages might have called our 'souls' or 'hearts.'"e; Building on Smith's previous work, To Flourish or Destruct examines the motivations intrinsic to this subjective experience: Why do people do what they doHow can we explain the activity that gives rise to all human social life and social structuresSmith argues that our actions stem from a motivation to realize what he calls natural human goods: ends that are, by nature, constitutionally good for all human beings. He goes on to explore the ways we can and do fail to realize these ends-a failure that can result in varying gradations of evil. Rooted in critical realism and informed by work in philosophy, psychology, and other fields, Smith's ambitious book situates the idea of personhood at the center of our attempts to understand how we might shape good human lives and societies.

The recent financial crisis led to sweeping reforms that inspired countless references to the financial reforms of the New Deal. Comparable to the reforms of the New Deal in both scope and scale, the 2,300-page Dodd-Frank Act of 2010-the main regulatory reform package introduced in the United States-also shared with New Deal reforms the assumption that the underlying cause of the crisis was misbehavior by securities market participants, exacerbated by lax regulatory oversight.With Wasting a Crisis, Paul G. Mahoney offers persuasive research to show that this now almost universally accepted narrative of market failure-broadly similar across financial crises-is formulated by political actors hoping to deflect blame from prior policy errors. Drawing on a cache of data, from congressional investigations, litigation, regulatory reports, and filings to stock quotes from the 1920s and '30s, Mahoney moves beyond the received wisdom about the financial reforms of the New Deal, showing that lax regulation was not a substantial cause of the financial problems of the Great Depression. As new regulations were formed around this narrative of market failure, not only were the majority largely ineffective, they were also often counterproductive, consolidating market share in the hands of leading financial firms. An overview of twenty-first-century securities reforms from the same analytic perspective, including Dodd-Frank and the Sarbanes-Oxley Act of 2002, shows a similar pattern and suggests that they too may offer little benefit to investors and some measurable harm.

Making "e;Nature"e; is the first book to chronicle the foundation and development of Nature, one of the world's most influential scientific institutions. Now nearing its hundred and fiftieth year of publication, Nature is the international benchmark for scientific publication. Its contributors include Charles Darwin, Ernest Rutherford, and Stephen Hawking, and it has published many of the most important discoveries in the history of science, including articles on the structure of DNA, the discovery of the neutron, the first cloning of a mammal, and the human genome.But how did Nature become such an essential institutionIn Making "e;Nature,"e; Melinda Baldwin charts the rich history of this extraordinary publication from its foundation in 1869 to current debates about online publishing and open access. This pioneering study not only tells Nature's story but also sheds light on much larger questions about the history of science publishing, changes in scientific communication, and shifting notions of "e;scientific community."e; Nature, as Baldwin demonstrates, helped define what science is and what it means to be a scientist.

Secularism is usually thought to contain the project of self-deification, in which humans attack God's authority in order to take his place, freed from all constraints. Julie E. Cooper overturns this conception through an incisive analysis of the early modern justifications for secular politics. While she agrees that secularism is a means of empowerment, she argues that we have misunderstood the sources of secular empowerment and the kinds of strength to which it aspires.Contemporary understandings of secularism, Cooper contends, have been shaped by a limited understanding of it as a shift from vulnerability to power. But the works of the foundational thinkers of secularism tell a different story. Analyzing the writings of Hobbes, Spinoza, and Rousseau at the moment of secularity's inception, she shows that all three understood that acknowledging one's limitations was a condition of successful self-rule. And while all three invited humans to collectively build and sustain a political world, their invitations did not amount to self-deification. Cooper establishes that secular politics as originally conceived does not require a choice between power and vulnerability. Rather, it challenges us-today as then-to reconcile them both as essential components of our humanity.

It is a truth widely acknowledged that if you're pregnant and can afford one, you're going to pick up a pregnancy manual. From What to Expect When You're Expecting to Pregnancy for Dummies, these guides act as portable mentors for women who want advice on how to navigate each stage of pregnancy. Yet few women consider the effect of these manuals-how they propel their readers into a particular system of care or whether the manual they choose reflects or contradicts current medical thinking.Using a sophisticated rhetorical analysis, Marika Seigel works to deconstruct pregnancy manuals while also identifying ways to improve communication about pregnancy and healthcare. She traces the manuals' evolution from early twentieth-century tomes that instructed readers to unquestioningly turn their pregnancy management over to doctors, to those of the women's health movement that encouraged readers to engage more critically with their care, to modern online sources that sometimes serve commercial interests as much as the mother's.The first book-length study of its kind, The Rhetoric of Pregnancy is a must-read for both users and designers of our prenatal systems-doctors and doulas, scholars and activists, and anyone interested in encouraging active, effective engagement.

Recent years have seen a renaissance of interest in the relationship between natural law and natural rights. During this time, the concept of natural rights has served as a conceptual lightning rod, either strengthening or severing the bond between traditional natural law and contemporary human rights. Does the concept of natural rights have the natural law as its foundation or are the two ideas, as Leo Strauss argued, profoundly incompatible?With The Foundations of Natural Morality, S. Adam Seagrave addresses this controversy, offering an entirely new account of natural morality that compellingly unites the concepts of natural law and natural rights. Seagrave agrees with Strauss that the idea of natural rights is distinctly modern and does not derive from traditional natural law. Despite their historical distinctness, however, he argues that the two ideas are profoundly compatible and that the thought of John Locke and Thomas Aquinas provides the key to reconciling the two sides of this long-standing debate. In doing so, he lays out a coherent concept of natural morality that brings together thinkers from Plato and Aristotle to Hobbes and Locke, revealing the insights contained within these disparate accounts as well as their incompleteness when considered in isolation. Finally, he turns to an examination of contemporary issues, including health care, same-sex marriage, and the death penalty, showing how this new account of morality can open up a more fruitful debate.

On June 30, 1908, a mysterious explosion erupted in the skies over a vast woodland area of Siberia. Known as the Tunguska Event, it has been a source of wild conjecture over the past century, attributed to causes ranging from meteors to a small black hole to antimatter. In this imaginative book, Michael Hampe sets four fictional men based on real-life scholars-a physicist (Gunter Hasinger and Steven Weinberg), a philosopher (Paul Feyerabend), a biologist (Adolf Portmann), and a mathematician (Alfred North Whitehead)-adrift on the open ocean, in a dense fog, to discuss what they think happened. The result is a playful and highly illuminating exploration of the definition of nature, mankind's role within it, and what its end might be.?Tunguska, Or the End of Nature uses its four-man setup to tackle some of today's burning issues-such as climate change, environmental destruction, and resource management-from a diverse range of perspectives. With a kind of foreboding, it asks what the world was like, and will be like, without us, whether we are negligible and the universe random, whether nature can truly be explained, whether it is good or evil, or whether nature is simply a thought we think. This is a profoundly unique work, a thrillingly interdisciplinary piece of scholarly literature that probes the mysteries of nature and humans alike.?
