Quipus, knotted structures of woollen or cotton cords, were used as a bureaucratic tool in the Inca state. In the absense of a writing system, numerals and possibly other pieces of information were encoded on the quipus by tying knots into elaborately structured coloured cords. Though interpretation of the quipu contents is far from complete, some information on Inca mathematics can be deducted from the analysis of ancient specimen, especially when combined with the results of anthropological and linguistic research in (...) contemporary Andean societies. In this paper, the quipus are introduced, their structure is explained, and some results on mathematical concepts of the Incas are presented based on a comparison of mathematical and anthropological literature on the subject.

Conciliationism holds that disagreement of apparent epistemic peers often substantially undermines rational confidence in our opinions. Uniqueness principles say that there is at most one maximally rational doxastic response to any given batch of total evidence. The two views are often thought to be tightly connected. This paper distinguishes two ways of motivating conciliationism, and two ways that conciliationism may be undermined by permissive accounts of rationality. It shows how conciliationism can flourish under certain strongly permissive accounts of rationality. This (...) occurs when the motivation for conciliationism does not come from taking disagreement as evidence of one's own rational failings. However, divorcing the motive for conciliating from worries about rationality does not remove a feature of conciliationism that some find troubling: that conciliationism can lead to cases of “rational toxicity,” in which the most rational response to one's evidence involves violating some rational ideal.

The globalization of production and trade has contributed to the rise in complex global value chains where the reach of state regulation is limited. As an alternative, private regulation, developed and administered by companies, industry associations, and nongovernmental organizations, has emerged to safeguard economic, environmental, and social sustainability in producer countries and along the value chain. The academic literature on private regulation in global value chains has grown over the last decade, but currently few major reviews of the research have (...) been undertaken. This paper examines peer-reviewed research in the relevant disciplines published in academic journals up to December 2011. Our goal is to identify and classify the topics and theories in the global value chain literature. We conclude that the number of articles explicitly examining private regulation, in a global value chain context, is relatively small when considering the importance and growth of these chains in the world’s economy. We also conclude that agriculture, forestry, and apparel manufacturing are the most often studied economic sectors; in contrast, other sectors, such as the information, communication and technology, with their complex global value chains, and often problematic environmental and social conditions, are understudied.

A central challenge of Amartya Sen’s comparative view of justice is to bring cultural diversity to bear on conceptualizing global justice, which includes building bridges across cultures that enable effective action, and rendering compatible the most beneficent of Rawlsian (or transcendental) intentions with irreducible cultural diversity. For social scientists meeting this challenge requires, first, taking account of variation of social practices in the social construction of meaning, and second, uncovering invisible frontiers of global justice that remain hidden due to conceptual (...) or empirical oversight. The latter is especially true for contemporary International Relations (IR) theory, which assumes state actors to be the main interlocutors in the global realm, and thus precludes consideration of micro-level forms of inter-national relations (understood as interaction among all types of actors that takes place across country borders and that bears traits of national identity). Alternatively, Sen’s micro-perspectival approach offers a welcome support for pluralist approaches that both appreciate non-state access to contestation in the international arena, and account for the meaning-in-use of fundamental norms (democracy, rule of law, human rights) in different cultural and inter-national contexts.

In this paper we develop a novel propositional semantics based on the framework of branching time. The basic idea is to replace the moment-history pairs employed as parameters of truth in the standard Ockhamist semantics by pairs consisting of a moment and a consistent, downward closed set of so-called transitions. Whereas histories represent complete possible courses of events, sets of transitions can represent incomplete parts thereof as well. Each transition captures one of the alternative immediate future possibilities open at a (...) branching point. The transition semantics exploits the structural resources a branching time structure has to offer and provides a fine-grained picture of the interrelation of modality and time. In addition to temporal and modal operators, a so-called stability operator becomes interpretable as a universal quantifier over the possible future extensions of a given transition set. The stability operator allows us to specify how and how far time has to unfold for the truth value of a sentence at a moment to become settled and enables a perspicuous treatment of future contingents. We show that the semantics developed along those lines generalizes and extends extant approaches: both Peirceanism and Ockhamism can be viewed as limiting cases of the transition approach that build on restricted resources only, and on both accounts, stability collapses into truth.

In this paper, I provide a thorough discussion and reconstruction of Bernard Bolzano’s theory of grounding and a detailed investigation into the parallels between his concept of grounding and current notions of normal proofs. Grounding (Abfolge) is an objective ground-consequence relation among true propositions that is explanatory in nature. The grounding relation plays a crucial role in Bolzano’s proof-theory, and it is essential for his views on the ideal buildup of scientific theories. Occasionally, similarities have been pointed out between Bolzano’s (...) ideas on grounding and cut-free proofs in Gentzen’s sequent calculus. My thesis is, however, that they bear an even stronger resemblance to the normal natural deduction proofs employed in proof-theoretic semantics in the tradition of Dummett and Prawitz. (shrink)

ABSTRACT Utopias in Africa is an emerging academic field. While we are witnessing an increasing number of fictional and ideological utopias, little attention is paid to lived utopias. The Green Camp Gallery Project is such a lived utopia, which predominantly strives for realizing desired future imaginations in daily practices. Localized in the urban context of Durban, in a derelict house in the industrial area, the Green Camp strives for a “simple post-growth life,” which is closely related to nature and the (...) philosophy of Ubuntu. In so doing, the Green Camp responds to the overlapping crisis of urbanity and offers an alternative future aspiration. The Green Camp is not perfect and it is not able to solve the deep problems of South African society, but it offers an “island” of hope and imagination in a challenging urban environment. At the same time the lived utopia reveals the agency of the urban marginalized and contradicts widespread assumptions concerning environmentalism. Based on a qualitative study, the article takes an unusual perspective by analyzing the imagination of lived utopia in an emerging utopian hotspot—Africa. (shrink)

Oregon is the only state in the United States where a physician may legally prescribe a lethal dose of barbiturate for a patient intending suicide. The Oregon Death with Dignity Act was passed by voters in 1994 and came into effect after much legal wrangling in October of 1997. At the same time, a cabinetmaker named Pat Matheny was struggling with progressive weakness from amyotrophic lateral sclerosis, or ALS. I met with Pat and his family for a lengthy interview in (...) October 1998 in Coos Bay, Oregon, for a television news report on his decision to get a lethal prescription. Below is an extract from that interview. On the day this introduction was written, 10 March 1999, Pat took the prescribed lethal overdose of barbiturates and died at home. His illness was taking his voice, he could not move his hands or legs, and breathing was becoming very difficult. His mother told me he knew that was for him. (shrink)

A comparison of Merge, a model of comprehension, and WEAVER, a model of production, raises five issues: merging models of comprehension and production necessarily creates feedback; neither model is a comprehensive account of word processing; the models are incomplete in different ways; the models differ in their handling of competition; as opposed to WEAVER, Merge is a model of metalinguistic behavior.

The transition semantics presented in Rumberg (J Log Lang Inf 25(1):77–108, 2016a) constitutes a fine-grained framework for modeling the interrelation of modality and time in branching time structures. In that framework, sentences of the transition language L_t are evaluated on transition structures at pairs consisting of a moment and a set of transitions. In this paper, we provide a class of first-order definable Kripke structures that preserves L_t-validity w.r.t. transition structures. As a consequence, for a certain fragment of L_t, validity (...) w.r.t. transition structures turns out to be axiomatizable. The result is then extended to the entire language L_t by means of a quite natural ‘Henkin move’, i.e. by relaxing the notion of validity to bundled structures. (shrink)

The internet could be an efficient political instrument if it were seen as part of a democracy where free and open discourse within a vital public sphere plays a decisive role. The model of deliberative democracy, as developed by Jürgen Habermas and Seyla Benhabib, serves this concept of democracy best. The paper explores first the model of deliberative democracy as a ‘two-track model’ in which representative democracy is backed by the public sphere and a developing civil society. Secondly, it outlines (...) the normative concept of the public sphere and its basic ideas, namely the uncoerced communication of equal participants with equal access and equal rights to intervene or propose themes. The third part for discussion shows how the internet could fit into this concept of public sphere and influence the quality of political debates, and emphasizes the important role it can play in the political process.

"As a 'rhetoric of the mean' (mesotes ideal), sensibility provides a positive catalog of emotionalization. This is because ethos as an emotional level is viewed as being able, through gentle emotions, to please, placate and achieve sympathy and virtue (Quintilian). Sensibility in literature creates a bridge between an 'art of the soul' that developed into a major subjective and personal factor in the 18th century and a sense of sociability that aimed to integrate the individual into the community. The goal (...) of this study is to provide, through a structural linking of the ethos of virtue and the 'rhetoric of the mean', a reading of literature of sensibility based on rhetoric and cultural history that can explain both its public success 'with the people' and the reasons for why it failed to meet its own claims."--Publisher's website.

How is it possible to develop an identity that lives from the meaningful relationship to a concrete tradition without falling into fundamentalist self-closure when trying to maintain this relationship? The present study addresses this question by interpreting Alasdair MacIntyre's traditional concept in response to the lack of orientation in contemporary society. The American philosopher Alasdair MacIntyre assumes that modern societies can only convey identity through the traditions they contain. He defines "tradition" as a discussion about the correct interpretation of the (...) traditional content. MacIntyre sees coexistence in plural societies as a permanent encounter of different, traditional identities that struggle to convince each other of the truthfulness of their own worldview. The consequence is not blind conflict, but rather the acquisition of cultural language skills: Real encounters occur when a tradition learns to understand its counterpart from its genuine perspective. In this way, MacIntyre makes communicative competence the guiding factor of its model. In conversation with Karl Barth's theology, the study further develops this model from a Protestant perspective. Barth is received as the 20th century theologian who most consistently thought of Christian identity in particular terms. Even more than for Barth, the self-assurance of Christian tradition is being put to the test today. The study develops a model of Christian orientation in pluralism, which is based on the interplay of cultural competence and trust in the sustainability of one's own religious identity. (shrink)

In einer gesteigerten Form der Memento-mori-Dichtung des Barock wurde die menschliche Sterblichkeit durch den Einsatz performativer Strategien für die Zeitgenoss*innen bereits zu Lebzeiten erfahrbar.

Suppose there comes a day when Homo sapiens has evolved into or been overtaken by techno sapiens. Will it then still make sense to speak of human beings as created in the image of God? What is the relevance of asking such a question today? I offer a sketch of the present state of development and discussion in artificial intelligence (AI) and artificial life (AL) and discuss some implications for the human condition. Taking into account both reality and fiction in (...) AI and AL, I hold that, regardless of the degree of realization, issues related to technological evolution inform the cultural agenda—at least the European–American one. I comment on antireductionist arguments and on arguments from philosophy and (history of) culture. I argue in favor of a consonance between neurotechnology and the Christian gospel in terms of realizing the marks of messianic life. However, issues of justice, reason versus nature, and perfection and finitude versus imperfection and immortality call for further illumination. Even though no principal opposition seems to exist between technological evolution and possible interpretations of the concept of the image of God (imago dei), a number of significant dissimilarities need to be addressed, such as the differences between technical improvement and forgiveness or transformation and between immortality and resurrection. The role of irregularity, disturbance, and error for creative processes in nature and culture is an exciting topic in science and technology as well as in theology. (shrink)

This article explores the possibility of resistance under conditions of extreme state power in liberal democracies. It examines the strategies of migrants without legal status who, when threatened with one of the most awesome powers of the liberal state—expulsion—shed their legal identity in order to escape the state’s reach. Remarkably, in doing so, they often succeed in preventing the state from exercising its sovereign powers. The article argues that liberal states are uniquely constrained in their dealing with undocumented migrants. Not (...) only are they forced to operate within the constraints of the international legal order—making repatriation contingent on the possession of identity documents—but the liberal state is also constitutionally limited in its exercise of coercion against the individual. The article concludes that it is those individuals who have the weakest claims against the liberal state that are most able to constrain its exercise of sovereignty. (shrink)

The article takes up J. P. Arnason's basic theoretical assumption that the western trajectory to modernity marks only one possibility of the modern constellation and that modernity has to be pluralized. Arnason's differentiation between a civilizational paradigm and a civilizational horizon allows us to acknowledge the ambivalent perceptions of modernity prevalent in the colonial and postcolonial encounter and gives space for counter-paradigms of modernity. Through a brief discussion of Indian reflections on modernity (P. Chatterjee, J. Alam) I want to argue (...) that the aspect of agency, marginalized in the philosophical and sociological debate on multiple modernities, has to be integrated into the theory. Examples from the Indian Himalayas should show how in everyday life as well as in the course of a social movement for regional autonomy `preferred futures' are negotiated on the basis of a reflexive balancing of `traditional' and `modern' elements which are articulated and joined in a self-made present. The article ends with a plaidoyer for an anthropology of modernity. (shrink)
