In an age where developments in biotechnology offer new possibilities for overcoming disease at a breathtaking rate, there is a certain timeliness in recalling C S Lewis’s farsighted depiction of “the magician’s bargain”, “that process whereby man surrenders object after object, and finally himself, to nature in return for power”.1 Lewis’s reflections on the implications of science’s quest for mastery over nature, outlined in his renowned essay The Abolition of Man, highlight the coercive tendencies of this yearning for control. In (...) practice, he argues, “power over nature turns out to be a power exercised by some men over other men with nature as its instrument”, and ironically proves not to be a power that humanity can wield for its chosen ends, but rather one that enslaves its pursuers to their appetite for domination . In seeking, through technical control, to transcend our bodily limits we embrace a technocratic mindset that, if adopted unconditionally, will lead us to regard our given identity as raw material to be “improved” by mechanical means.This collection of essays aims to give fresh voice to this warning in the face of the very latest in biotechnological innovations. In the words of the editors, it is intended as a “wake up call,” informing readers of the exciting possibilities for health care in the future, and equipping them with the concepts with which to appraise them from a Christian perspective. Like C S Lewis, the contributors are keen to dispel any suggestion that …. (shrink)

This paper reports on an investigation of gaze patterns and other non-verbal behavior in dyadic, problem-solving based interactions. In a planning activity, participants are given an instruction sheet and a physical map of a zoo. Both participants must coordinate their actions to find a common solution to the problem. This paper aims at examining how activity-based interactions vary from other interactions, such as everyday conversation and story-telling. The findings of this paper suggest that participants’ non-verbal behavior, such as smiling, nodding (...) and in particular gaze, varies according to the interactional organization. In egalitarian interactions gaze directed at the other person occurs together with meta-task utterances, for example personal and humorous remarks. This paper highlights the role of gaze in task-based interactions to show that gaze is an integral part of stance taking, as it enables participants to position themselves in a joint activity.

The iCat is a user-interface robot with the ability to express a range of emotions through its facial features. This article summarizes our research to see whether we can increase the believability and likability of the iCat for its human partners through the application of gaze behaviour. Gaze behaviour serves several functions during social interaction such as mediating conversation flow, communicating emotional information and avoiding distraction by restricting visual input. There are several types of eye and head movements that are (...) necessary for realizing these functions. We designed and evaluated a gaze behaviour system for the iCat robot that implements realistic models of the major types of eye and head movements found in living beings: vergence, vestibulo ocular reflexive, smooth pursuit movements and gaze shifts. We discuss how these models are integrated into the software environment of the iCat and can be used to create complex interaction scenarios. We report about some user tests and draw conclusions for future evaluation scenarios. (shrink)

In her Introduction, Tymieniecka states the core theme of the present book sharply: Is culture an excess of nature's prodigious expansiveness - an excess which might turn out to be dangerous for nature itself if it goes too far - or is culture a 'natural', congenial prolongation of nature-life? If the latter, then culture is assimilated into nature and thus would lose its claim to autonomy: its criteria would be superseded by those of nature alone. Of course, nature and culture (...) may both still be seen as being absorbed by the inner powers of specifically human inwardness, on which view, human being, caught in its own transcendence, becomes separated radically in kind from the rest of existence and may not touch even the shadow of reality except through its own prism. Excess, therefore, or prolongation? And on what terms? The relationship between culture and nature in its technical phase demands a new elucidation. Here this is pursued by excavating the root significance of the 'multiple rationalities' of life. In contrast to Husserl, who differentiated living types according to their degree of participation in the world, the phenomenology of life disentangles living types from within the ontopoietic web of life itself. The human creative act reveals itself as the Great Divide of the Logos of Life - a divide that does not separate but harmonizes, thus dispelling both naturalistic and spiritualistic reductionism.

This book is a specialized monograph on interpolation and definability, a notion central in pure logic and with significant meaning and applicability in all areas where logic is applied, especially computer science, artificial intelligence, logic programming, philosophy of science and natural language. Suitable for researchers and graduate students in mathematics, computer science and philosophy, this is the latest in the prestigous world-renowned Oxford Logic Guides, which contains Michael Dummet's Elements of intuitionism, J. M. Dunn and G. Hardegree's Algebraic Methods in (...) Philosophical Logic, H. Rott's Change, Choice and Inference: A Study of Belief Revision and Nonmonotonic Reasoning, P. T. Johnstone's Sketches of an Elephant: A Topos Theory Compendium: Volumes 1 and 2, and David J. Pym and Eike Ritter's Reductive Logic and Proof Search: Proof theory, semantics and control. (shrink)
