Michael Dummett is a leading contemporary philosopher whose work on the logic and metaphysics of language has had a lasting influence on how these subjects are conceived and discussed. This volume contains some of the most provocative and widely discussed essays published in the last fifteen years, together with a number of unpublished or inaccessible writings. Essays included are: "What is a Theory of Meaning?," "What do I Know When I Know a Language?," "What Does the Appeal to Use Do (...) for the Theory of Meaning?," "Language and Truth," "Truth and Meaning," "Language and Communication," "The Source of the Concept of Truth," "Mood, Force, and Convention," "Frege and Husserl on Reference," "Realism," "Existence," "Does Quantification Involve Identity?," "Could there be Unicorns?," "Causal Loops," "Common Sense and Physics," "Testimony and Memory," "What is Mathematics About?," "Wittgenstein on Necessity: Some Reflections," and "Realism and Anti-Realism." Serving well as a companion to Dummett's other collections, the essays in this volume are not forbiddingly technical or specialized, and have relevance to many areas of analytic philosophy. (shrink)

Focusing on the breakthrough field of molecular engineering--a new technology enabling scientists to build tiny machines atom by atom--the author offers projections on how this technological revolution will affect the future of computer science, space travel, medicine, and manufacturing.

In both the philosophical and visual sense, ‘seeing is believing’ does not apply to nanotechnology, for there is nothing even remotely visible to create proof of existence. On the atomic and molecular scale, data is recorded by sensing and probing in a very abstract manner, which requires complex and approximate interpretations. More than in any other science, visualization and creation of a narrative becomes necessary to describe what is sensed, not seen. Nevertheless, many of the images generated in science and (...) popular culture are not related to data at all, but come from visualizations and animations frequently inspired or created directly from science fiction. Likewise, much of this imagery is based on industrial models and is very mechanistic in nature, even though nanotechnology research is at a scale where cogs, gears, cables, levers and assembly lines as functional components appear to be highly unlikely. However, images of mechanistic nanobots proliferate in venture capital circles, popular culture, and even in the scientific arena, and tend to dominate discourse around the possibilities of nanotechnology. The authors put forward that this new science is ultimately about a shift in our perception of reality from a purely visual culture to one based on sensing and connectivity. (shrink)

Book reviewed in this article: The Imperative of Responsibility. In Search of an Ethics for the Technological Age. By Hans Jonas.

Disputes about realism should be construed as disputes not about a class of entities, but about the truth‐value of the statements in a given class. For what reality consists in is not determined just by what objects there are, but by what propositions hold good: the world is the totality of facts, not of things. However, the rejection of bivalence is not a sufficient ground for rejecting realism. A genuine rejection of realism amounts to the view that logical constants classically (...) understood do not make sense. (shrink)
