Is logic a good tool for making decisions? Can it make us better listeners and help us find coherence in views that we disagree with? Is Sherlock Holmes actually good at logic? Patrick Girard addresses these and other questions by presenting logic as the guardian of coherence. Logic, Girard argues, finds coherence in the patterns of reasoning across science, religion, and everyday decision making. It helps communities engage safely by replacing contentious debates with shared, constructive reasoning – logic provides neutral ground for the healthy pursuit of common goals and interests. Logic in the Wild employs common sense language, eschewing technical jargon, symbols, and equations. Girard’s attention focuses on logic’s power to find what unites the complex and the simple, the abstract and the concrete, the theoretical and the practical. In treating logic not as a passive subject to learn but as an active discipline to engage with, Logic in the Wild teaches us to identify patterns in our own reasoning, which inevitably helps us better confront questions central to everyday life.

Logical consequence is the relation that obtains between premises and conclusion(s) in a valid argument. Orthodoxy has it that valid arguments are necessarily truth-preserving, but this platitude only raises a number of further questions, such as: how does the truth of premises guarantee the truth of a conclusion, and what constraints does validity impose on rational belief? This volume presents thirteen essays by some of the most important scholars in the field of philosophical logic. The essays offer ground-breaking new insights into the nature of logical consequence; the relation between logic and inference; how the semantics and pragmatics of natural language bear on logic; the relativity of logic; and the structural properties of the consequence relation.

This book, presented in two parts, offers a slow introduction to mathematical logic, and several basic concepts of model theory, such as first-order definability, types, symmetries, and elementary extensions. Its first part, Logic Sets, and Numbers, shows how mathematical logic is used to develop the number structures of classical mathematics. The exposition does not assume any prerequisites; it is rigorous, but as informal as possible. All necessary concepts are introduced exactly as they would be in a course in mathematical logic; but are accompanied by more extensive introductory remarks and examples to motivate formal developments. The second part, Relations, Structures, Geometry, introduces several basic concepts of model theory, such as first-order definability, types, symmetries, and elementary extensions, and shows how they are used to study and classify mathematical structures. Although more advanced, this second part is accessible to the reader who is either already familiar with basic mathematical logic, or has carefully read the first part of the book. Classical developments in model theory, including the Compactness Theorem and its uses, are discussed. Other topics include tameness, minimality, and order minimality of structures. The book can be used as an introduction to model theory, but unlike standard texts, it does not require familiarity with abstract algebra. This book will also be of interest to mathematicians who know the technical aspects of the subject, but are not familiar with its history and philosophical background.

This book offers a social, political, and aesthetic critique of transhumanism and of the accelerating growth of scientific knowledge generally. Rather than improving our lives, science and technology today increasingly leave us debilitated and infantilized. It is time to restrain the runaway ambitions of technoscientific knowledge. The transhumanist goal of human enhancement encapsulates a range of dangerous social pathologies. Like transhumanism itself, these pathologies are rooted in, or in reaction to, the ethos of ‘more’. It’s a cultural love affair with excess, which is prompted by the libertarian standards of our cultural productions. But the attempt to live at the speed of an electron is destined for failure. In response, the author offers a naturalistic account of human flourishing where we attend to the natural rhythms of life. The interdisciplinary orientation of Transhumanism, Nature, and the Ends of Science makes it relevant to scholars and students across a wide range of disciplines, including social and political philosophy, philosophy of technology, science and technology studies, environmental studies, and public policy.

One of the New York Times Book Review's Ten Best Books of the Year Winner of the James Beard Award Author of How to Change Your Mind and the #1 New York Times Bestsellers In Defense of Food and Food Rules What should we have for dinner? Ten years ago, Michael Pollan confronted us with this seemingly simple question and, with The Omnivore’s Dilemma, his brilliant and eye-opening exploration of our food choices, demonstrated that how we answer it today may determine not only our health but our survival as a species. In the years since, Pollan’s revolutionary examination has changed the way Americans think about food. Bringing wide attention to the little-known but vitally important dimensions of food and agriculture in America, Pollan launched a national conversation about what we eat and the profound consequences that even the simplest everyday food choices have on both ourselves and the natural world. Ten years later, The Omnivore’s Dilemma continues to transform the way Americans think about the politics, perils, and pleasures of eating.
