Book Description
According to George Berkeley (1685-1753), there is fundamentally nothing in the world but minds and their ideas. Ideas are understood as pure phenomenal 'feels' which are momentarily had by a single perceiver, then vanish. Surprisingly, Berkeley tries to sell this idealistic philosophical system as a defense of common-sense and an aid to science. However, both common-sense and Newtonian science take the perceived world to be highly structured in a way that Berkeley's system does not appear to allow. Kenneth L. Pearce argues that Berkeley's solution to this problem lies in his innovative philosophy of language. The solution works at two levels. At the first level, it is by means of our conventions for the use of physical object talk that we impose structure on the world. At a deeper level, the orderliness of the world is explained by the fact that, according to Berkeley, the world itself is a discourse 'spoken' by God - the world is literally an object of linguistic interpretation. The structure that our physical object talk - in common-sense and in Newtonian physics - aims to capture is the grammatical structure of this divine discourse. This approach yields surprising consequences for some of the most discussed issues in Berkeley's metaphysics. Most notably, it is argued that, in Berkeley's view, physical objects are neither ideas nor collections of ideas. Rather, physical objects, like forces, are mere quasi-entities brought into being by our linguistic practices.

The Oxford Handbook of Berkeley
Author:
Publisher: Oxford University Press
ISBN: 0190873426
Category : Philosophy
Languages : en
Pages : 704
Book Description
The Oxford Handbook of Berkeley is a compendious examination of a vast array of topics in the philosophy of George Berkeley (1685-1753), Anglican Bishop of Cloyne, the famous idealist and most illustrious Irish philosopher. Berkeley is best known for his denial of the existence of material substance and his insistence that the only things that exist in the universe are minds (including God) and their ideas; however, Berkeley was a polymath who contributed to a variety of different disciplines, not well distinguished from philosophy in the eighteenth century, including the theory and psychology of vision, the nature and functioning of language, the debate over infinitesimals in mathematics, political philosophy, economics, chemistry (including his favoured panacea, tar-water), and theology. This volume includes contributions from thirty-four expert commentators on Berkeley's philosophy, some of whom provide a state-of-the-art account of his philosophical achievements, and some of whom place his philosophy in historical context by comparing and contrasting it with the views of his contemporaries (including Mandeville, Collier, and Edwards), as well as with philosophers who preceded him (such as Descartes, Locke, Malebranche, and Leibniz) and others who succeeded him (such as Hume, Reid, Kant, and Shepherd).

The Notions of George Berkeley
Author: James Hill
Publisher: Bloomsbury Publishing
ISBN: 1350299707
Category : Philosophy
Languages : en
Pages : 185
Book Description
George Berkeley's doctrine of notions is often disparaged or dismissed. In a systematic interpretation and positive reconstruction of the doctrine, James Hill presents Berkeley's understanding of the inner sphere and self-awareness, and reassesses the widely held view of Berkeley as an empiricist. Examining the development of Berkeley's philosophy from the early notebooks to the late Siris, Hill sets out how knowledge by notion involves a radical rejection of the perceptual model of self-cognition and of the attempt to frame our knowledge of the inner by analogy with the outer. He points to Berkeley's divergence from the assumption among rationalists and empiricists that we know our selves and our mental acts by idea, or by an immediate presentation before the mind. Weaving together Berkeley's conception of the intellect, conceptual thought, mathematics, ethics and theology in the light of the doctrine of notions, Hill invites us to treat Berkeley's philosophy of mind as distinct from the empiricist tradition. This cutting edge reflection on the doctrine of notions is essential reading for students and scholars specialising in Berkeley as well as early modern accounts of the self, perception and God.

A Pattern Language
Author: Christopher Alexander
Publisher: Oxford University Press
ISBN: 0190050357
Category : Architecture
Languages : en
Pages : 1216
Book Description
You can use this book to design a house for yourself with your family; you can use it to work with your neighbors to improve your town and neighborhood; you can use it to design an office, or a workshop, or a public building. And you can use it to guide you in the actual process of construction. After a ten-year silence, Christopher Alexander and his colleagues at the Center for Environmental Structure are now publishing a major statement in the form of three books which will, in their words, "lay the basis for an entirely new approach to architecture, building and planning, which will we hope replace existing ideas and practices entirely." The three books are The Timeless Way of Building, The Oregon Experiment, and this book, A Pattern Language. At the core of these books is the idea that people should design for themselves their own houses, streets, and communities. This idea may be radical (it implies a radical transformation of the architectural profession) but it comes simply from the observation that most of the wonderful places of the world were not made by architects but by the people. At the core of the books, too, is the point that in designing their environments people always rely on certain "languages," which, like the languages we speak, allow them to articulate and communicate an infinite variety of designs within a forma system which gives them coherence. This book provides a language of this kind. It will enable a person to make a design for almost any kind of building, or any part of the built environment. "Patterns," the units of this language, are answers to design problems (How high should a window sill be? How many stories should a building have? How much space in a neighborhood should be devoted to grass and trees?). More than 250 of the patterns in this pattern language are given: each consists of a problem statement, a discussion of the problem with an illustration, and a solution. As the authors say in their introduction, many of the patterns are archetypal, so deeply rooted in the nature of things that it seemly likely that they will be a part of human nature, and human action, as much in five hundred years as they are today.

Berkeley's Doctrine of Signs
Author: Manuel Fasko
Publisher: Walter de Gruyter GmbH & Co KG
ISBN: 3111197581
Category : Philosophy
Languages : en
Pages : 242
Book Description
This volume focuses on Berkeley's doctrine of signs. The 'doctrine of signs' refers to the use that Berkeley makes of a phenomenon that is central to a great deal of everyday discourse: one whereby certain perceivable entities are made to stand in for (as 'signs' of) something else. Things signified might be other perceivable entities or they might also be unperceivable notions - such as the meanings of words. From his earliest published work, A New Theory of Vision in 1710, to those works written towards the end of life, including Alciphron in 1732, Berkeley is at pains to emphasise the crucial role that sign-usage, particularly (but not only) in language, plays in human life. Berkeley also connects sign-usage to our (human) relationship with God: an issue that was right of the heart of his philosophical project. The contributions in this volume explore the myriad ways that Berkeley built on such insights to better understand a range of philosophical issues - issues of epistemology, language, perception, mental representation, mathematics, science, and theology. The aim of this volume is to establish that the doctrine of signs can be seen as one of the unifying themes of Berkeley's philosophy. What's more, this theme is one which spans his whole philosophical corpus; not just his best-known works like the Principles and the Three Dialogues, but also his works on science, mathematics, and theology.

George Berkeley and Romanticism
Author: Chris Townsend
Publisher: Oxford University Press
ISBN: 019266221X
Category : Literary Criticism
Languages : en
Pages : 239
Book Description
George Berkeley's mainstream legacy amongst critics and philosophers, from Samuel Johnson to Bertrand Russell, has tended to concern his claim that the objects of perception are in fact nothing more than our ideas. Yet there's more to Berkeley than idealism alone, and the poets now grouped under the label 'Romanticism' took up Berkeley's ideas in especially strange and surprising ways. As this book shows, the poets Blake, Wordsworth, Coleridge, and Shelley focused less on Berkeley's arguments for idealism than they did on his larger, empirically-derived claim that nature constitutes a kind of linguistic system. It is through that 'ghostly language' that we might come to know ourselves, each other, and even God. This book is a reappraisal of the role that Berkeley's ideas played in Romanticism, and it pursues his spiritualized philosophy across a range of key Romantic-period poems. But it is also a re-reading of Berkeley himself, as a thinker who was deeply concerned with language and with written—even literary—style. In that sense, it offers an incisive case study into the reception of philosophical ideas into the workings of poetry, and of the role of poetics within the history of ideas more broadly.

The World Atlas of Language Structures
Author: Martin Haspelmath
Publisher: OUP Oxford
ISBN: 0191531243
Category : Language Arts & Disciplines
Languages : en
Pages : 712
Book Description
The World Atlas of Language Structures is a book and CD combination displaying the structural properties of the world's languages. 142 world maps and numerous regional maps - all in colour - display the geographical distribution of features of pronunciation and grammar, such as number of vowels, tone systems, gender, plurals, tense, word order, and body part terminology. Each world map shows an average of 400 languages and is accompanied by a fully referenced description of the structural feature in question. The CD provides an interactive electronic version of the database which allows the reader to zoom in on or customize the maps, to display bibliographical sources, and to establish correlations between features. The book and the CD together provide an indispensable source of information for linguists and others seeking to understand human languages. The Atlas will be especially valuable for linguistic typologists, grammatical theorists, historical and comparative linguists, and for those studying a region such as Africa, Southeast Asia, North America, Australia, and Europe. It will also interest anthropologists and geographers. More than fifty authors from many different countries have collaborated to produce a work that sets new standards in comparative linguistics. No institution involved in language research can afford to be without it.

George Berkeley
Author: Tom Jones
Publisher: Princeton University Press
ISBN: 0691217491
Category : Biography & Autobiography
Languages : en
Pages : 648
Book Description
A comprehensive intellectual biography of the Enlightenment philosopher In George Berkeley: A Philosophical Life, Tom Jones provides a comprehensive account of the life and work of the preeminent Irish philosopher of the Enlightenment. From his early brilliance as a student and fellow at Trinity College Dublin to his later years as Bishop of Cloyne, Berkeley brought his searching and powerful intellect to bear on the full range of eighteenth-century thought and experience. Jones brings vividly to life the complexities and contradictions of Berkeley’s life and ideas. He advanced a radical immaterialism, holding that the only reality was minds, their thoughts, and their perceptions, without any physical substance underlying them. But he put forward this counterintuitive philosophy in support of the existence and ultimate sovereignty of God. Berkeley was an energetic social reformer, deeply interested in educational and economic improvement, including for the indigenous peoples of North America, yet he believed strongly in obedience to hierarchy and defended slavery. And although he spent much of his life in Ireland, he followed his time at Trinity with years of travel that took him to London, Italy, and New England, where he spent two years trying to establish a university for Bermuda, before returning to Ireland to take up an Anglican bishopric in a predominantly Catholic country. Jones draws on the full range of Berkeley’s writings, from philosophical treatises to personal letters and journals, to probe the deep connections between his life and work. The result is a richly detailed and rounded portrait of a major Enlightenment thinker and the world in which he lived.
