Music in German Philosophy
Music in German Philosophy
Stefan Lorenz Sorgner,Oliver Fürbeth
¥353.16
Though many well-known German philosophers have devoted considerable attention to music and its aesthetics, surprisingly few of their writings on the subject have been translated into English. Stefan Lorenz Sorgner, a philosopher, and Oliver Furbeth, a musicologist, here fill this important gap for musical scholars and students alike with this compelling guide to the musical discourse of ten of the most important German philosophers, from Kant to Adorno.Music in German Philosophy includes contributions from a renowned group of ten scholars, including some of today's most prominent German thinkers, all of whom are specialists in the writers they treat. Each chapter consists of a short biographical sketch of the philosopher concerned, a summary of his writings on aesthetics, and finally a detailed exploration of his thoughts on music. The book is prefaced by the editors' original introduction, presenting music philosophy in Germany before and after Kant, as well as a new introduction and foreword to this English-language addition, which places contemplations on music by these German philosophers within a broader intellectual climate.
Victorian Popularizers of Science
Victorian Popularizers of Science
Bernard Lightman
¥353.16
The ideas of Charles Darwin and his fellow Victorian scientists have had an abiding effect on the modern world. But at the time The Origin of Species was published in 1859, the British public looked not to practicing scientists but to a growing group of professional writers and journalists to interpret the larger meaning of scientific theories in terms they could understand and in ways they could appreciate. Victorian Popularizers of Science focuses on this important group of men and women who wrote about science for a general audience in the second half of the nineteenth century.Bernard Lightman examines more than thirty of the most prolific, influential, and interesting popularizers of the day, investigating the dramatic lecturing techniques, vivid illustrations, and accessible literary styles they used to communicate with their audience. By focusing on a forgotten coterie of science writers, their publishers, and their public, Lightman offers new insights into the role of women in scientific inquiry, the market for scientific knowledge, tensions between religion and science, and the complexities of scientific authority in nineteenth-century Britain.
A Book of Britain: The Lore, Landscape and Heritage of a Treasured Countryside
A Book of Britain: The Lore, Landscape and Heritage of a Treasured Countryside
Johnny Scott
¥368.46
In this remarkable, landmark publication, countryman Sir Johnny Scott evokes all that is romantic about the British countryside, its people, customs and traditions. Over its 600 gloriously illustrated pages, Johnny draws on his wisdom and knowledge to reveal a forgotten culture, and encourages us all to rediscover a beautiful Britain. “I always think of nightingales when spring arrives in the south of England and winter is still reluctant to release its grip north of the Border. I heard my first as a very small child while staying with my grandparents on the Ashdown Forest. My sister woke me one night with an excited whisper, 'A nightingale! You must listen to the nightingale sing!' Together we sat on the window seat, gazing across moonlit lawns towards the forest. At that moment, as if nature had not already done enough to impress, the most wonderful sound I had ever heard filled the silence, as the nightingale started to sing. A rapid succession of varied, unconstructed notes, some harsh, some liquid, sung with great exuberance and vigour, changed to a long, slow, pleading song that rose in volume to a sudden piteous crescendo, before reverting to a tune of jollity and mirth. In my mind's eye I saw it erect and glowing, somewhere in the darkness among the oak trees, but no amount of searching that morning produced a single golden feather.” Throughout the pages of A Book of Britain, Johnny Scott celebrates the landscape and people and reveals why, through centuries of careful management, conservation and cultivation, Britain looks as it does. We discover Royal forests and protected oaks; learn animal behaviour and how best to observe wildlife whether on the moors or in your garden; we learn about traditional country sports from familiar hobbies such as fishing and shooting to lesser-known activities such as “swan upping”. Johnny teaches us to look to animals and nature to predict the weather, and reveals many customs and traditions that are in danger of being lost. This book is a gift in every sense – not only in its sheer scope and presence, but in the rich legacy it will leave behind for future generations.
Marine Macroecology
Marine Macroecology
Jon D. Witman,Kaustuv Roy
¥394.36
Pioneered in the late 1980s, the concept of macroecology-a framework for studying ecological communities with a focus on patterns and processes-revolutionized the field. Although this approach has been applied mainly to terrestrial ecosystems, there is increasing interest in quantifying macroecological patterns in the sea and understanding the processes that generate them. Taking stock of the current work in the field and advocating a research agenda for the decades ahead, Marine Macroecology draws together insights and approaches from a diverse group of scientists to show how marine ecology can benefit from the adoption of macroecological approaches.Divided into three parts, Marine Macroecology first provides an overview of marine diversity patterns and offers case studies of specific habitats and taxonomic groups. In the second part, contributors focus on process-based explanations for marine ecological patterns. The third part presents new approaches to understanding processes driving the macroecolgical patterns in the sea. Uniting unique insights from different perspectives with the common goal of identifying and understanding large-scale biodiversity patterns, Marine Macroecology will inspire the next wave of marine ecologists to approach their research from a macroecological perspective.
Murder by Accident
Murder by Accident
Enders, Jody
¥447.34
Over fifty years ago, it became unfashionable-even forbidden-for students of literature to talk about an author's intentions for a given work. In Murder by Accident, Jody Enders boldly resurrects the long-disgraced concept of intentionality, especially as it relates to the theater.Drawing on four fascinating medieval events in which a theatrical performance precipitated deadly consequences, Enders contends that the marginalization of intention in critical discourse is a mirror for the marginalization-and misunderstanding-of theater. Murder by Accident revisits the legal, moral, ethical, and aesthetic limits of the living arts of the past, pairing them with examples from the present, whether they be reality television, snuff films, the "e;accidental"e; live broadcast of a suicide on a Los Angeles freeway, or an actor who jokingly fired a stage revolver at his temple, causing his eventual death. This book will force scholars and students to rethink their assumptions about theory, intention, and performance, both past and present.
Intuition in Medicine
Intuition in Medicine
Braude, Hillel D.
¥447.34
Intuition is central to discussions about the nature of scientific and philosophical reasoning and what it means to be human. In this bold and timely book, Hillel D. Braude marshals his dual training as a physician and philosopher to examine the place of intuition in medicine.Rather than defining and using a single concept of intuition-philosophical, practical, or neuroscientific-Braude here examines intuition as it occurs at different levels and in different contexts of clinical reasoning. He argues that not only does intuition provide the bridge between medical reasoning and moral reasoning, but that it also links the epistemological, ontological, and ethical foundations of clinical decision making. In presenting his case, Braude takes readers on a journey through Aristotle's Ethics-highlighting the significance of practical reasoning in relation to theoretical reasoning and the potential bridge between them-then through current debates between regulators and clinicians on evidence-based medicine, and finally applies the philosophical perspectives of Reichenbach, Popper, and Peirce to analyze the intuitive support for clinical equipoise, a key concept in research ethics. Through his phenomenological study of intuition Braude aims to demonstrate that ethical responsibility for the other lies at the heart of clinical judgment.?Braude's original approach advances medical ethics by using philosophical rigor and history to analyze the tacit underpinnings of clinical reasoning and to introduce clear conceptual distinctions that simultaneously affirm and exacerbate the tension between ethical theory and practice. His study will be welcomed not only by philosophers but also by clinicians eager to justify how they use moral intuitions, and anyone interested in medical decision making.

The Soil (Collins New Naturalist Library, Book 77)
B. N. K. Davis,N. Walker,D. F. Ball
¥456.66
The soil is one of the great unsung disappearing resources, with over 100m tonnes being destroyed every year. This edition is exclusive to newnaturalists.com The soil is the work place of farmers and gardeners, but it is also a fascinating environment inhabited by insects that can leap into the air to a record height, multilegged scavengers that are vital to the decomposition of plant matter and the long, thin, entwining strands of thousands of species of fungi. Although soil plays a vital role in the functioning of the world, it has often been overlooked, mainly because it contains a huge range of different fields, all of which have become specialities in their own right. This book brings together specialists in these fields to give a broad overview of the staggering advances that have been made since Sir John Russel's The World Of Soil was published in this series in 1947. The first two chapters introduce the physical structure of the soil. The next four chapters deal with the specific animals and plants and how they exploit this environment. The final four chapters describe how these animals interact and how man has used and abused the soil in his striving to gain more and more from this resource.
The Open Sea
The Open Sea
Alister Hardy
¥456.66
The New Naturalist editors believe this to be the greatest general work on the subject ever written. This edition is exclusive to newnaturalists.com Professor Alistair Hardy is truly obsessed by animals of the sea - devotedly enthusiastic about the nature of their adaptations and life histories, brilliantly critical in the examination of their mysteries, acutely lucid (and at the same time highly artistic) in his de*ions of them in his arresting plates. To describe the relatively unknown and mysterious world of plankton is a task that the greatest of marine zoologists might boggle at. Yet the plankton is to the sea what vegetation is to the land. The study of plankton is a complex discipline which few amateur naturalists have had the privilege to enjoy. Never before has such a synthesis of knowledge been attempted in a community of animals so mysterious, yet so important. Professor Hardy has grasped this problem in a new and exciting way; and at least the common reader can discern the pattern of life that dominates two-thirds of the world’s surface.
