Long awaited and eagerly anticipated, this remarkable volume allows English-speaking readers to experience a profound dialogue between the German philosopher Martin Heidegger and the Swiss psychiatrist Medard Boss. A product of their warm friendship, _Zollikon Seminars_ chronicles an extraordinary exchange of ideas. Heidegger strove to transcend the bounds of philosophy while Boss and his colleagues in the scientific community sought to understand their patients and their world. The result: the best and clearest introduction to Heidegger's philosophy available. Boss approached Heidegger (...) asking for help in reflective thinking on the nature of Heidegger's work. Soon they were holding annual two-week meetings in Boss's home in Zollikon, Switzerland. The protocols from these seminars, recorded by Boss and reviewed, corrected, and supplemented by Heidegger himself, make up one part of this volume. They are augmented by Boss's record of the conversations he had with Heidegger in the days between seminars and by excerpts from the hundreds of letters the philosopher wrote to Boss between 1947 and 1971.

In this article we explore the emergence of a cluster of social movement organisations that have critically taken issue with nanotechnology in Germany, the UK and internationally. By applying concepts borrowed from Social Movement Research we demonstrate that this cluster is a ‘spin-off’ from the preceding movement against agrofood biotechnology, however, never succeeds in mobilizing a comparable ‘antinanotechnology movement’. We argue that the turn toward participatory and deliberative practices that is characteristic of nanotechnology policy and, to a major extent, is (...) based on the perceived threat of a ‘public backlash’ against nanotechnology, while being of little political impact, reinforces the activity of these critical organisations through the provision of political opportunities. We further argue that the stagnation of these organisations can be explained by low policy impact and low public responsiveness respectively and conclude that their trajectories hinge to a major extent on policy impact and the responsiveness of the mass-public. We end by making a concluding remark about the limits to the project of democratizing social contention through public engagement. (shrink)

Unification was originally introduced in automated deduction and term rewriting, but has recently also found applications in other fields. In this article, we give a survey of the results on unification obtained in two closely related, yet different, application areas of unification: description logics and modal logics.
