Even if we know all relevant descriptive facts about an act, we can still be uncertain about its moral acceptability. Most literature on how to act under such normative uncertainty operates on moral realism, the metaethical view that there are objective moral facts. Lay people largely report anti-realist intuitions, which poses the question of how these intuitions affect their interpretation and handling of normative uncertainty. Results from two quasi-experimental studies (total N = 365) revealed that most people did not interpret (...) normative uncertainty as referring to objective moral facts but rather as uncertainty regarding one’s own view, uncertainty regarding the culturally accepted view or as the result of ambivalence. Especially the anti-realist majority of participants interpreted normative uncertainty different to how it is described in the literature on choice under normative uncertainty. Metaethical views were also associated with lay peoples’ choice of uncertainty reduction strategies and with assumptions about the intended aim of such strategies. The current findings suggest that empirical investigations of normative uncertainty might benefit from considering folk metaethical pluralism, as the lay public largely disagrees with the metaethical assumptions underlying the current discourse on choice under normative uncertainty.

People can be uncertain in their moral judgments. Philosophers have argued that such uncertainty can either refer to the underlying empirical facts (empirical uncertainty) or to the normative evaluation of these facts itself (normative uncertainty). Psychological investigations of this distinction, however, are rare. In this paper, we combined factor-analytical and experimental approaches to show that empirical and normative uncertainty describe two related but different psychological states. In Study 1, we asked N = 265 participants to describe a case of moral (...) uncertainty and to rate different aspects of their uncertainty about this case. Across this wide range of moral scenarios, our items loaded onto three reliable factors: lack of information, unclear consequences, and normative uncertainty. In Study 2, we confirmed this factor structure using predefined stimulus material. N = 402 participants each rated eight scenarios that systematically varied in their degree of uncertainty regarding the consequences of the described actions and in the value conflict that was inherent to them. The empirical uncertainty factors were mainly affected by the introduction of uncertainty regarding consequences, and the normative uncertainty factor was mainly affected by the introduction of value conflict. Our studies provide evidence that the distinction between empirical and normative uncertainty accurately describes a psychological reality. We discuss the relevance of our findings for research on moral judgments and decision-making, and folk metaethics. (shrink)

Haunted by dreams of a powerful red tide, Odd Thomas, accompanied by two otherworldly sidekicks--his dog Boo and the Chairman of the Board--is drawn to a small California coastal town, where nothing is at it appears and where he confronts overwhelming and sinister forces out to stop his quest.

Arbitrariness and systematicity are two of language’s most fascinating properties. Although both are characterizations of the mappings between signals and meanings, their emergence and evolution in communication systems has generally been explored independently. We present an experiment in which both arbitrariness and systematicity are probed. Participants invent signs from scratch to refer to a set of items that share salient semantic features. Through interaction, the systematic re-use of arbitrary signal elements emerges.

Der Streit um die Prinzipien der Theorienentwicklung hat in den Jahren seit dem Erscheinen von TH. S. KUHNS "Die Struktur wissen schaftlicher Revolutionen" mannigfache und lebhafte AufSerungen pro und contra hervorgerufen. Die Gegenposition wird im wesent lichen durch die Namen POPPER und LAKATOS charakterisiert. Die Kontroverse erweist sich als eine solche zwischen synchronischer und diachronischer, zwischen systematischer und historischer Betrach tungsweise. 1st die Entwicklung der Wissenschaften, wie man es nach KUHN glauben kann, in entscheidendem MafSe aufSeren Einfliissen und Zufalligkeiten ausgesetzt, (...) oder gibt es nicht doch rationale, rein wissenschaftsimmanente Kriterien, auf Grund derer eine Entwicklung im Sinne eines Fortschrittes zu immer besseren, richtigeren und lei stungsfahigeren Theorien moglich ist? Eine wesentliche Schwierigkeit, um dabei weiterzukommen, besteht darin, dafS es keine Moglichkeit zu geben scheint, eine Theorie zu bewerten, zu entscheiden, welche von zwei Theorien "wahrscheinlicher, richtiger, besser oder leistungs fahiger" ist. Wenn es geiange, eine numerische Bewertung von Hypothesen und Theorien in dieser Richtung zu finden, so ware damit auch ein Weg gewiesen, die Entwicklung der Theorien nicht nur zu rekon struieren, sondern vielleicht auch zu lei ten. Die Bewertung einer Theorie im Sinne ihrer Richtigkeit ist bisher nicht gelungen. Wenn POPPER, insbesondere in seinen spaten Arbeiten ("Objective Knowl edge"), die Auffassung vertritt, dafS die Entwicklung der Wissen schaften im Sinne einer immer grofSeren Wahrheitsahnlichkeit von statten gehe, so ist das bei ihm ein reiner Glaube, der auf Grund seines Modells von Versuch und Irrtum postuliert wird.

Justice, Sustainability, and Security not only enhances our knowledge of these issues, but it teases out our moral dimensions and offer prescriptions for how governments and global actors might craft their policies to better consider their effects on the global human condition.

This junior/senior level text is devoted to a study of first-order logic and its role in the foundations of mathematics: What is a proof? How can a proof be justified? To what extent can a proof be made a purely mechanical procedure? How much faith can we have in a proof that is so complex that no one can follow it through in a lifetime? The first substantial answers to these questions have only been obtained in this century. The most (...) striking results are contained in Goedel's work: First, it is possible to give a simple set of rules that suffice to carry out all mathematical proofs; but, second, these rules are necessarily incomplete - it is impossible, for example, to prove all true statements of arithmetic. The book begins with an introduction to first-order logic, Goedel's theorem, and model theory. A second part covers extensions of first-order logic and limitations of the formal methods. The book covers several advanced topics, not commonly treated in introductory texts, such as Trachtenbrot's undecidability theorem. Fraissé's elementary equivalence, and Lindstroem's theorem on the maximality of first-order logic. (shrink)

The current study introduces the Multi-Motive Grid Mobility in an age-stratified sample that aims to disentangle six motive components – hope of success, hope of affiliation, hope of power, fear of failure, fear of rejection, and fear of power – in mobility-related and mobility-unrelated scenarios. Similar to the classical Multi-Motive Grid, we selected 14 picture scenarios representing seven mobility and seven non-mobility situations. The scenarios were combined with 12 statements from the MMG. Both the MMG-M and MMG were assessed to (...) allow comparability between psychometric criteria. The results of confirmatory factor analyses yielded a good model fit for a six-factor solution with an additional mobility factor for the MMG-M. Internal consistency of the items was similar to the MMG. Lastly, we investigated associations between the motive components and mobility-related variables. We found that risk awareness was positively related to all fear components in both mobility and non-mobility scenarios. Most importantly, physical constraint was positively associated with fear of rejection and fear of power in mobility situations underlining the importance to create support systems to reduce these concerns in people’s everyday lives.

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.
