Humans think and communicate in very flexible and schematic ways, and a Spatial Data Infrastructure (SDI) for the Amazon and associated information system ontologies should reflect this flexibility and the adaptive nature of human cognition in order to achieve semantic interoperability. In this paper I offer a conceptual investigation of SDI and explore the nature of cultural schemas as expressions of indigenous ontologies and the challenges of semantic interoperability across cultures. Cultural schemas are, in essence, our ontologies, but they are (...) markedly different than classical formal ontologies. They shape our ontological commitments to what exists in the world as well as the ways in which we approach and engage the world. And while they help structure our understanding of the world in which we are embedded, they are associative and flexible. They help to focus our attention to particular details of our experiences and give them salience, yet they cannot be simply reduced to a series of extracted features. They allow us to make meaning of the contextualized, cultural experience in which we are always immersed. An SDI is a shared social-technological-informational structure that, if it is to be useful and successful for sustainability in the Amazon, must incorporate and use indigenous cultural schemas. Indigenous communities must have the ability to contribute to the collection of geospatial data and their contributions recognized as legitimate forms of knowledge. In order for the SDI to work, it must recognize the larger cultural landscape to which cultural schemas can connect to the ready-to-hand elements of salient cultural experiences. (shrink)

Ontologies are being used by information scientists in order to facilitate the sharing of meaningful information. However, computational ontologies are problematic in that they often decontextualize information. The semantic content of information is dependent upon the context in which it exists and the experience through which it emerges. For true semantic interoperability to occur among diverse information systems, within or across domains, information must remain contextualized. In order to bring more context to computational ontologies, we introduce culture as an essential (...) concept for information science. Culture helps to focus our attention on and make meaning of relevant extrapersonal structures and their qualities and dimensions that comprise the context and background of the world. In our approach, culture is integral to the study of semantics and, consequently, the study of ontologies and information technologies. The meaning we make of entities and phenomena in the world is always shaped by our cultural experience. If we understand culture as the emergent interplay of intrapersonal cognitive structures and extrapersonal structures of the world, then the notion of cognitive and cultural schemas becomes essential to understanding ontology and the ways in which we might achieve authentic semantic interoperability among diverse information systems. We explore the nature of ontologies and reconceptualize them as cultural schemas. Our proposal is an alternative to the historical path from philosophical ontology to computational ontologies as one that adheres primarily to the notion of ontology as a categorization and classification system. The obvious implication for ontology as categorization is that there is a single objective world that exists and that it can be described as entirely separate from the person observing it. We draw upon Heidegger’s examination of ontology to ground ontology in a phenomenological perspective, enabling it to remain flexible and adaptable and to accommodate context. (shrink)

Upon what philosophical foundation are semantic network graphs based? Does this foundation allow for the legitimization of other semantic networks and ontological diversity? How can we design our computational and informational systems to accommodate this ontological diversity and the variety of semantic networks? Are semantic networks segmentations of larger semantic landscapes? This paper explores semantic networks from a Heideggerian existentialist and phenomenological perspective. The analysis presented uses cultural schema theory to bridge the syntactic and lexical elements to the semantic and (...) conceptual dimensions of semantic network graphs and offers reasons why the viability of such graphs as they are currently constructed are insufficient for creating semantic interoperability for our informationtechnologies. Reconceptualizing semantic networks as cultural landscapes offers us. (shrink)

In this chapter we will investigate the nature of abstraction in detail, its entwinement with logical thinking, and the general role it plays for the mind. We find that non-logical capabilities are not only important for input processing, but also for output processing. Human beings jointly use analytic and embodied capacities for thinking and acting, where analytic thinking mirrors reflection and logic, and where abstraction is the form in which embodied thinking is revealed to us. We will follow the philosophical (...) analyses of Heidegger and Polanyi to elaborate the fundamental difference between abstraction and logics and how they come together in the mind. If computational approaches to mind are to be successful, they must be able to recognize meaningful and salient elements of a context and engage in abstraction. Computational minds must be able to imagine and volitionally blend abstractions as a way of recognizing gestalt contexts. And it must be able to discern the validity of these blendings in ways that, in humans, arise from a sensus communis. (shrink)

Environmental concerns and the complex issues and dilemmas raised by animal rights pose fundamental questions for philosophers. The essays in this welcome collection put environmental thinking into the broader context of philosophical thought. Distinguished contributions from key thinkers, including Mary Midgley, Stephen Clark, J.Baird Callicott, Holmes Rolston, Dale Jamieson and John Haldane, focus on our attitudes to animals and the environment as critically determined by deeper philosophical concerns. Timothy Chappell's useful introduction provides a guide to the issues and dilemmas and (...) links the diverse arguments and themes. Examining whaling, animal captivity, and specicism amongst other topics, this book adds substantially to the contemporary debate in environmental philosophy. (shrink)

This contribution honours the memory of Hans- Georg Gadamer from a theological perspective. A first section reflects on the complex and often ambiguous nature of his relationship with theology and theologians, and with issues of faith and religion. Anecdotes and biographical information point to the seeming lack of interest, at least in contemporary theology, reflected in his work, but also to the warm reception that he continued to receive in theological circles, both with regard to his person and his work. (...) A second section briefly illus trates how his description of the hermeneutical conversation is practically demonstrated in what is called ecumenical hermeneutics, and how many of the notions and convictions of contemporary hermeneutical theory have indeed become common in these circles. The official study document A Treasure in Earthen Vessels. An Instru ment for an Ecumeni cal Re flection on Hermeneutics (1998, Faith and Order Paper No. 182) of the World Council of Churches is used to illustrate this. A third and final section underlines some of the formal similarities between this form of ecumenical hermeneutics and Gadamer's self- understanding of his own life project. It is argued that, whether his impact on the ecumenical church was direct or indirect, the matter-of-factness with which present-day ecumenism uses hermeneutical categories and convictions underscores Gadamer's own insight that “theologians see in my work a confirmation of their own needs.” S.

In the present state of philosophy in the English-speaking world, to choose to talk about sense data may seem perverse. What could be more boring for one's audience than to attempt variations on so threadbare a theme? And worse, what could be more unfashionable in the aftermath of Wittgenstein and Austin? My reasons for selecting this unpromising topic are twofold. First, the general theme of this series of lectures is empiricism. And whatever meanings we put upon that ambiguous word, it (...) is clear that as a matter of history the problems of perception have been important problems for nearly all those philosophers who would consider themselves to be empiricists. And however unsatisfactory sense datum theories of perception may now be held to be, such theories have been central to the empiricist tradition. Secondly, it is important not to be too much impressed by the fact that a particular philosophical opinion is fashionable or unfashionable. The former certainly does not guarantee its truth nor the latter its falsity. It has often been remarked that philosophical opinions are very rarely refuted. Instead they fall out of vogue only to return some years later in another guise. It is perhaps time to take another look at the notion of sense data. The most ingenious and persistent attacks on analyses of perception in terms of sense data have been at best indecisive, as Professor Ayer showed in his reply to Austin's Sense and Sensibilia.

This book is a collection of critical essays that examine a radical shift in focus and orientation. In the challenge to the hermeneutics of suspicion, the adoption of alternative reading strategies, and the investigation of well-being, this collection is an analogue of a new discourse that has immensely enriched literary studies in the last decade.

John Henry Newman is widely acknowledged to be an important theologian. However Newman commentators suggest that his work has received little recognition by philosophers. The general consensus has been that until the latter part of the twentieth century Newman has been an isolated philosophical figure. This essay offers an historical re-evaluation of Newman's philosophical reception in order to explore whether or not his significance has been underestimated. The historical method is used in the analysis and assessment of this question. The (...) study therefore probes the general philosophical reaction to Newman's work in the nineteenth and early twentieth century. In doing so the essay offers an historical investigation and re-evaluation of the claims of Newman having a negligible philosophical legacy. (shrink)
