'The best collection I've read in ages: every poem contains something unexpected and unexpectedly powerful. This is serious, modern, ambitious and bold work – the kind of poetry you hope to find, and rarely do' – Nick Laird John Ashbery called Timothy Donnelly’s previous collection, The Cloud Corporation, ‘The poetry of the future, here today’. The Problem of the Many sees Donnelly, one of the most influential poets of his generation, focused less on the future than the end of history: these richly textured and intellectually capacious poems often seem to attempt nothing less than a circumscription of the totality of human experience. The book contains the already widely praised ‘Hymn to Life’, which opens with a litany of what we have made extinct; elsewhere, from an immediately contemporary vantage, Donnelly confronts the clutter and devastation that civilization has left us as he strives towards a beauty that we still need, along the way enlisting agents as various as Prometheus, Jonah, Flamin’ Hot Cheetos, NyQuil, Nietzsche, and Alexander the Great. The Problem of the Many refers to the famous philosophical problem of what defines the larger aggregate – a cloud, a crowd – which Donnelly extends to address the subject of individual boundary, identity and belonging. Donnelly’s solutions may be wholly poetic, but he has succeeded in speaking as deeply to these profound and urgent issues as any writer currently at work.

When many people are involved in an activity, it is often difficult, if not impossible, to pinpoint who is morally responsible for what, a phenomenon known as the ‘problem of many hands.’ This term is increasingly used to describe problems with attributing individual responsibility in collective settings in such diverse areas as public administration, corporate management, law and regulation, technological development and innovation, healthcare, and finance. This volume provides an in-depth philosophical analysis of this problem, examining the notion of moral responsibility and distinguishing between different normative meanings of responsibility, both backward-looking (accountability, blameworthiness, and liability) and forward-looking (obligation, virtue). Drawing on the relevant philosophical literature, the authors develop a coherent conceptualization of the problem of many hands, taking into account the relationship, and possible tension, between individual and collective responsibility. This systematic inquiry into the problem of many hands pertains to discussions about moral responsibility in a variety of applied settings.

Argues for a more robust conception of responsibility in public life than prevails in contemporary democracies.

Single-volume account of methods used in dealing with the many-body problem and the resulting physics. Single-particle approximations, second quantization, many-body perturbation theory, Fermi fluids, superconductivity, many-boson systems, more. Each chapter contains well-chosen problems. Only prerequisite is basic understanding of elementary quantum mechanics. 1967 edition.

This book differs from its predecessor, Lieb & Mattis Mathematical Physics in One Dimension, in a number of important ways. Classic discoveries which once had to be omitted owing to lack of space ? such as the seminal paper by Fermi, Pasta and Ulam on lack of ergodicity of the linear chain, or Bethe's original paper on the Bethe ansatz ? can now be incorporated. Many applications which did not even exist in 1966 (some of which were originally spawned by the publication of Lieb & Mattis) are newly included. Among these, this new book contains critical surveys of a number of important developments: the exact solution of the Hubbard model, the concept of spinons, the Haldane gap in magnetic spin-one chains, bosonization and fermionization, solitions and the approach to thermodynamic equilibrium, quantum statistical mechanics, localization of normal modes and eigenstates in disordered chains, and a number of other contemporary concerns.

Superb introduction for nonspecialists covers Feynman diagrams, quasi particles, Fermi systems at finite temperature, superconductivity, vacuum amplitude, Dyson's equation, ladder approximation, and more. "A great delight." — Physics Today. 1974 edition.

Study Edition

Whether we're buying a pair of jeans, ordering a cup of coffee, selecting a long-distance carrier, applying to college, choosing a doctor, or setting up a 401(k), everyday decisions—both big and small—have become increasingly complex due to the overwhelming abundance of choice with which we are presented. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions you make before you even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis, anxiety, and perpetual stress. And, in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression. In The Paradox of Choice, Barry Schwartz explains at what point choice—the hallmark of individual freedom and self-determination that we so cherish—becomes detrimental to our psychological and emotional well-being. In accessible, engaging, and anecdotal prose, Schwartz shows how the dramatic explosion in choice—from the mundane to the profound challenges of balancing career, family, and individual needs—has paradoxically become a problem instead of a solution. Schwartz also shows how our obsession with choice encourages us to seek that which makes us feel worse. By synthesizing current research in the social sciences, Schwartz makes the counter intuitive case that eliminating choices can greatly reduce the stress, anxiety, and busyness of our lives. He offers eleven practical steps on how to limit choices to a manageable number, have the discipline to focus on those that are important and ignore the rest, and ultimately derive greater satisfaction from the choices you have to make.

This important collection brings together both established figures and new researchers to offer fresh perspectives on the ever-controversial subject of the history of witchcraft. Using Keith Thomas's Religion and the Decline of Magic as a starting point, the contributors explore the changes of the last twenty-five years in the understanding of early modern witchcraft, and suggest new approaches, especially concerning the cultural dimensions of the subject. Witchcraft cases must be understood as power struggles, over gender and ideology as well as social relationships, with a crucial role played by alternative representations. Witchcraft was always a contested idea, never fully established in early modern culture but much harder to dislodge than has usually been assumed. The essays are European in scope, with examples from Germany, France, and the Spanish expansion into the New World, as well as a strong core of English material.

This classic work, first published in 1912, has never been supplanted as an approachable introduction to the theory of philosophical enquiry. It gives Russell's views on such subjects as the distinction between appearance and reality, the existence and nature of matter, idealism, knowledge by acquaintance and by description, induction, truth and falsehood, the distinction between knowledge, error and probable opinion, and the limits and value of philosophical knowledge.
