MISSING CHILD Kate Elliot's suburban life turns upside down when her sister is shot and her niece kidnapped. Unsure of whom to trust, she turns to FBI agent Marcus O'Brian. But Kate doesn't want to leave the case to the authorities. Against the handsome agent's orders, she tracks her niece to Paris, and the City of Light quickly becomes a city of danger. Marcus can't explain why he feels such a strong connection with the headstrong woman, but soon he's taking on the role of Kate's protector. Yet when the kidnappers demand a ransom Kate can't deliver, he's not sure how much longer he can keep her alive. Now Marcus has the next twenty-four hours to save a stolen child and the woman he's grown to love.

Ever since Saul Kripke and others developed a semantic interpretation for modal logic, 'possible worlds' has been a much debated issue in contemporary metaphysics. To propose the idea of a possible world that differs in some way from our actual world - for example a world where the grass is red or where no people exist - can help us to analyse and understand a wide range of philosophical concepts, such as counterfactuals, properties, modality, and of course, the notions of possibility and necessity. This book examines the ways in which possible worlds have been used as a framework for considering problems in logic and argument analysis. The book begins with a non-technical introduction to the basic ideas of modal logic in terms of Kripke's possible worlds and then moves on to a discussion of 'possible for' and 'possible that'. The central chapters examine questions of meaning, epistemic possibility, temporal logic, metaphysics, and impossibility. Girle also investigates how the idea of a possible world can be put to use in different areas of philosophy, the problems it may raise, and the benefits that can be gained.

Sequestered within the heart of a cosmopolitan city is an exotic world—a place where diamonds, astronomically priced, are bought and sold on the strength of a handshake, and business disputes are resolved according to ancient Jewish principles of arbitration. Yet it is also a modern industry facing the same fundamental global changes affecting all businesses today.In Diamond Stories, Renée Rose Shield leads us into the unexamined realm of wholesale diamond traders in New York. Related to several well-respected traders, she had unprecedented access to a society normally closed to outside inquiry. Here she deftly blends her personal relationship and her anthropological training to provide an insightful exploration of this tradition-bound industry, the new challenges it faces, and the ways both industry and individuals adapt to and endure change.Shield begins with a fascinating history of diamond mining, combining the story of the De Beers cartel, the role of Jews in the trade, and the part diamonds have played both in war and liberation. Throughout, she incorporates commentary by current diamond traders. Succeeding chapters explore the evolving nature of both the global trade and the New York diamond district. Shield takes a close look at the increasingly complex ethnic makeup of the district, illuminates the rarely documented work done by women, chronicles the resilient system of arbitration, and reveals the ways in which many traders work well into their eighties and nineties. Their long lives of work, cushioned by the trade's social environment, offer hints for successful aging in general.

Introduction to Logic is clear and concise, uses interesting examples (many philosophical in nature), and has easy-to-use proof methods. Its key features, retained in this Third Edition, include: simpler ways to test arguments, including an innovative proof method and the star test for syllogisms; a wide scope of materials, suiting it for introductory or intermediate courses; engaging examples, from philosophy and everyday life; useful for self-study and preparation for standardized tests, like the LSAT; a reasonable price (a third the cost of some competitors); and exercises that correspond to the free LogiCola instructional program. This Third Edition: improves explanations, especially on areas that students find difficult; has a fuller explanation of traditional Copi proofs and of truth trees; and updates the companion LogiCola software, which now is touch friendly (for use on Windows tablets and touch monitors), installs more easily on Windows and Macintosh, and adds exercises on Copi proofs and on truth trees. You can still install LogiCola for free (from http://www.harryhiker.com/lc or http://www.routledge.com/cw/gensler).
