Jürgen Habermas's Theory of Cosmopolitanism

Robert Fine
In this paper we explore the sustained and multifaceted attempt of Jürgen Habermas to reconstruct Kant's theory of cosmopolitan right for our own times. In a series of articles written in the post-1989 period, Habermas has argued that the challenge posed both by the catastrophes of the twentieth century, and by social forces of globalization, has given new impetus to the idea of cosmopolitan justice that Kant first expressed. He recognizes that today we cannot simply repeat Kant's eighteenth-century vision: that if we are to grapple with the complexities of present-day problems, it is necessary to iron out certain inconsistencies in Kant's thinking, radicalize it where its break from the old order of nation-states is incomplete, socialize it so as to draw out the connections between perpetual peace and social justice, and modernize it so as to comprehend the "differences both in global situation and conceptual framework that now separate us from him."1 His basic intuition, however, is that Kant's idea of cosmopolitan right is as relevant to our times as it was to Kant's own. If it was Kant's achievement to formulate the idea of cosmopolitanism in a modern philosophical form, Habermas takes up the challenge posed by Karl-Otto Apel: to "think with Kant against Kant" in reconstructing this idea. What follows is a critical assessment of Habermas's response to this challenge. We focus here on the dilemmas he faces in grounding his normative commitment to cosmopolitan politics and in reconciling his cosmopolitanism with the national framework in which he developed his ideas of constitutional patriotism and deliberative democracy.

Nature conservation and urban development control in the Portuguese planning system: a new impetus against old praxis?

Teresa Fidelis
Abstract Natura 2000 areas bring a new incentive to assess the performance of land-use planning in protecting environmental values from the impacts of development pressures. In the last decades, urban growth and consequent environmental impacts on natural areas have been a major concern for the Portuguese land-use planning system. Sprawl around sensitive areas has been revealed to be a persistent phenomenon in spite of the increasing challenges underlying land-use plans. This article critically analyses the content of three main documents recently adopted by the Portuguese government , the ,National Strategy for Sustainable Development', the ,National Policy Programme for Spatial Planning' and the ,Sector Plan for Natura 2000' , seeking prospects to innovate future plans at lower levels in order to prevent additional pressures on natural areas. First, the article reviews the recent theoretical debate on planning for the protection of natural areas. Results evidenced by recent EU evaluation reports are used to propose a set of guidelines to evaluate planning guidance at national level. Second, it critically analyses the three planning documents, bearing in mind the main features of the planning system and the proposed guidelines. The article is concluded with a discussion of their potential, exploring whether they bring a new impetus to the role of land-use planning against an outdated and persistent praxis, or whether, on the contrary, further efforts to strengthen planning guidance remain to be formulated.

Very High Critical Field and Superior Jc -Field Performance in NdFeAsO0.82F0.18 with Tc of 51 K,

Xiaolin Wang
A new family of oxypnictide superconductors, LaFeAsO0.89F0.11, brings new impetus to the field of high-temperature superconductivity. In this work, we show that the upper critical field values Hc2 (48 K) = 13 T and Hc2(0) can exceed 80,230 T in a high-pressure-fabricated NdO0.82F0.18FeAs bulk sample with Tc of 51 K. We also demonstrate the superior performance of supercurrent density in fields for this new superconductor. [source]
