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.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

This paper explores an initially attractive principle connecting beliefs in general with beliefs about what beliefs are rational. The principle turns out to be violated by intuitively rational beliefs in some situations. The paper lays out some options for reacting to this fact.

Formally inclined epistemologists often theorize about ideally rational agents—agents who exemplify rational ideals, such as probabilistic coherence, that human beings could never fully realize. This approach can be defended against the well-known worry that abstracting from human cognitive imperfections deprives the approach of interest. But a different worry arises when we ask what an ideal agent should believe about her own cognitive perfection (even an agent who is in fact cognitively perfect might, it would seem, be uncertain of this fact). (...) Consideration of this question reveals an interesting feature of the structure of our epistemic ideals: for agents with limited information, our epistemic ideals turn out to conflict with one another. This suggests that we must revise the way we see ideal agents in epistemic theorizing. (shrink)

Die Studie untersucht Gottesbilder von Kindern und Jugendlichen. Im Zentrum stehen Zeichnungen von Sechst- und Zehntklässlern, die Brüche und Spannungen enthalten. Ungewohnte Darstellungen kommen zum Vorschein: Gott nimmt beispielsweise eine Auszeit, er beschützt und überwacht die Welt oder er erscheint als Fata Morgana. Die Untersuchung orientiert sich methodologisch an der dokumentarischen Bild- und Textinterpretation: Sie schafft erstmals Einsichten in das Ringen von Kindern und Jugendlichen um die eigene Gottesvorstellung. Im Fokus steht die Frage, inwiefern Kinder und Jugendliche von sich aus (...) theologisieren. Ermöglicht der empirische Zugriff, besondere Typen des Gottesbildes zu identifizieren, so greifen exemplarisch ausgewählte systematisch-theologische Modelle diese Problemstellungen auf. Deren reflektierte Anwendung eröffnet die Möglichkeit, ein passgenaues Setting für ein weiteres Theologisieren zu konturieren. (shrink)

It is commonly acknowledged that, in order to test a theoretical hypothesis, one must, in Duhem' s phrase, rely on a "theoretical scaffolding" to connect the hypothesis with something measurable. Hypothesis-confirmation, on this view, becomes a three-place relation: evidence E will confirm hypothesis H only relative to some such scaffolding B. Thus the two leading logical approaches to qualitative confirmation--the hypothetico-deductive (H-D) account and Clark Glymour' s bootstrap account--analyze confirmation in relative terms. But this raises questions about the philosophical interpretation (...) of the technical conditions these accounts describe. What does it mean to say that E confirms H "relative to B"? How should we interpret the relation we are trying to analyze? (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)

"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.

This inclusive cross-cultural study rethinks the nexus between engineering education and context. In so doing the book offers a reflection on contextual boundaries with an overall boundary crossing ambition and juxtaposes important cases of critical participation within engineering education with sophisticated scholarly reflection on both opportunities and discontents. Whether, and in what way engineering education is or ought to be contextualized or de-contextualized is an object of heated debate among engineering educators. The uniqueness of this study is that this debate (...) is given comprehensive coverage - presenting both instrumentally inclined as well as radical positions on transforming engineering education. In contextualizing engineering education, this book offers diverse commentary from a range of disciplinary, meta- and interdisciplinary perspectives on how cultural, professional, institutional, and educational systems contexts shape histories, structural dynamics, ideologies and challenges as well as new pathways in engineering education. Topics addressed include examining engineering education in countries ranging from India to America, to racial and gender equity in engineering education and incorporating social awareness into the area. Using context as "bridge" this book confronts engineering education head on. Contending engineering ideologies and corresponding views on context are juxtaposed with contending discourses of reform. The uniqueness of the book is that it brings together scholars from the humanities, the social sciences and engineering from Europe - both East and West - with the United States, China, Brazil, India and Australia.

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)

Wie kam der Mensch zu der Vorstellung, dass es Götter gibt? Enthält die Sprache des Mythos Hinweise auf Ursprung und Entwicklung des religiösen Denkens? In einer wissenschaftshistorischen Studie wird hier die Theorie des Klassischen Philologen Hermann Usener (1834-1905) vom Ursprung der Religion (1896) und deren Rezeption in den Werken von Albrecht Dieterich, Ludwig Radermacher, Aby Warburg und Walter F. Otto untersucht. Mit seiner strukturanalytisch entwickelten Lehre von der religiösen Begriffsbildung hat Usener die seit der Romantik geführte Ursprungsdebatte neu aufgerollt und (...) dazu inspiriert, sein Projekt aufzugreifen und kritisch fortzuschreiben.

Applied philosophy is experiencing its “golden days,” as Kasper Lippert-Rasmussen says in his insightful introduction to A Companion to Applied Philosophy. Applied philosophy seems to be distinguished from its opposite, pure philosophy, usually understood as traditional philosophy, which deals with subjects such as free will, consciousness, or knowledge in philosophical subdisciplines like ethics, metaphysics, and epistemology. To embrace applied philosophy could thus mean to advocate for a philosophy that deals with questions “relevant to ‘the important questions of everyday life,’” as (...) Leslie Stevenson puts it, as opposed to questions that arise from within the subdisciplines of pure philosophy. (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)

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.

Sterelny’s Thought in a Hostile World ([ 2003 ]) presents a complex, systematically structured theory of the evolution of cognition centered on a concept of decoupled representation. Taking Godfrey-Smith’s ([ 1996 ]) analysis of the evolution of behavioral flexibility as a framework, the theory describes increasingly complex grades of representation beginning with simple detection and culminating with decoupled representation, said to be belief-like, and it characterizes selection forces that drive evolutionary transformations in these forms of representation. Sterelny’s ultimate explanatory target (...) is the evolution of human agency. This paper develops a detailed analysis of the main cognitive aspects. It is argued that some of the major claims are not correct: decoupled representation as defined doesn’t capture belief-like representation, and, properly understood, decoupled representation turns out to be ubiquitous among multicellular animals. However, some of the key ideas are right, or along the right lines, and suggestions are made for modifying and expanding the conceptual framework. (shrink)

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.

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)

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.

The transition semantics presented in Rumberg :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 \ 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 \-validity w.r.t. transition structures. As a consequence, for a certain fragment of \, validity w.r.t. transition structures turns (...) out to be axiomatizable. The result is then extended to the entire language \ by means of a quite natural ‘Henkin move’, i.e. by relaxing the notion of validity to bundled structures. (shrink)
