Metaphysical presuppositions are important for guiding scientific practices and research. The success of twentieth-century biology, for instance, is largely attributable to presupposing that complex biological processes are reducible to elementary components. However, some biologists have challenged the sufficiency of reductionism for investigating complex biological phenomena and have proposed alternative presuppositions like organicism. In this article, contemporary cancer research is used as a case study to explore the importance of metaphysical presuppositions for guiding research. The predominant paradigm directing cancer research is (...) the somatic mutation theory, in which mutated genes are presumed to be ultimately responsible for explaining carcinogenesis. This reductionistic approach to cancer has been criticised recently, and an organistic approach has been proposed. The article concludes with a discussion of the reciprocal interaction of metaphysical presuppositions and scientific practices for investigating cancer's complex nature. (shrink)

Since the turn of the millennium Jürgen Habermas's contributions to social and political theory have been increasingly turning toward matters of religious and theological relevance. This article weighs up the import and coherence of Habermas's recent reflections on religious belief and its relationship to reason and modernity in Western philosophical culture. At the forefront of the analysis stands Habermas's conception of appropriate “limits” and “boundaries” between the domains of knowledge and faith and the possibility and desirability of a process of (...) “discursive translation” of contents of religious language into forms of secularized, universalizing moral argument. The article defends the thesis that Habermas's project of a rapprochement between contents of religious language and norms of scientific thinking founders on its attempt to reconcile too many different, conceptually centrifugal tendencies. However, these difficulties and inconsistencies in Habermas's recent thinking remain instructive and ought to continue to engage the interest of scholars concerned today with the question of how far the philosophy of the social sciences can and cannot accommodate commitments to theism in the practice of research.

The article considers Jürgen Habermas's views on the relationship between postmetaphysical philosophy and religion. It outlines Habermas's shift from his earlier, apparently dismissive attitude towards religion to his presently more receptive stance. This more receptive stance is evident in his recent emphasis on critical engagement with the semantic contents of religion and may be characterized by two interrelated theses: the view that religious contributions should be included in political deliberations in the informally organized public spheres of contemporary democracies, though translated (...) into a secular language for the purposes of legislation and formal decision making and the view that postmetaphysical philosophy should seek to salvage the semantic contents of religious traditions in order to supply the evocative images, exemplary figures, and inspirational narratives it needs for its social and political projects. With regard to, it argues that the translation requirement impairs the political autonomy of religious believers and other metaphysically inclined citizens, suggesting that this difficulty could be alleviated by making a distinction between epistemologically authoritarian and non-authoritarian religious beliefs. With regard to, it argues that the salvaging operation is not as straightforward as Habermas seems to suppose and that social and political philosophy may not be able to tap the semantic power of religious traditions without relying on metaphysical assumptions; it concludes that, here, too, a distinction between authoritarian and non-authoritarian approaches to knowledge and validity may be useful.
