An epistemic logic is built up on the basis of an analysis of two skeptical arguments. the method used is to first construct an inference relation appropriate to epistemic contexts and introduce "a knows that..." as an operator giving rise to sentences closed with respect to this new concept of inference. soundness and completeness proofs are provided using auxiliary three-valued valuations.

It is argued that the preservation of truth by an inference relation is of little interest when premiss sets are contradictory. The notion of a level of coherence is introduced and the utility of modal logics in the semantic representation of sets of higher coherence levels is noted. It is shown that this representative role cannot be transferred to first order logic via frame theory since the modal formulae expressing coherence level restrictions are not first order definable. Finally, an inference (...) relation, calledyielding, is introduced which is intermediate between the coherence preservingforcing relation introduced elsewhere by the authors and the coherence destroying, inference relation of classical logic.

This collection offers an extensive framework of comparative and individual studies assessing the place of Luke-Acts in the historiography of ancient Judaism and the Greco-Roman world, whilst also examining further developments in early Christian historiography up to Eusebius and Theodoret. Additional contributions concentrate on systematic questions concerning the literary genre and conception of Luke-Acts.

The use of digital presentation tools such as PowerPoint is ubiquitous; however we still do not know much about the persuasiveness of these programs. Examining the use of visual analogy and visual chronology, in particular, this paper explores the use of visual argumentation in a Keynote presentation by Al Gore. It illustrates how images function as an integrated part of Gores reasoning.

During 1995, there was a major shift in the United Kingdom in the debate of whether it is right for nurses to strike. The Royal College of Nursing, the former advocate of a non-industrial action policy, moved towards the UNISON position that industrial action is ethical in some circumstances, as well as the necessary thing to do. The authors, both nurses and UNISON officials, look at the reasons for this change and why UNISON’s historical position sees industrial action as an (...) effective weapon in defending services, as well as wages and jobs. It can be right to strike. (shrink)

This essay introduces a special report from The Hastings Center entitled Democracy in Crisis: Civic Learning and the Reconstruction of Common Purpose, which grew out of a project supported by the John S. and James L. Knight Foundation. This multiauthored report offers wide‐ranging assessments of increasing polarization and partisanship in American government and politics, and it proposes constructive responses to this in the provision of objective information, institutional reforms in government and the electoral system, and a reexamination of cultural and (...) political values needed if democracy is to function well in a pluralistic and diverse society. The essays in the special report explore the norms of civic learning and institutions, social movements, and communal innovations that can revitalize civic learning in practice. This introductory essay defines and explains the notion of civic learning, which is a lynchpin connecting many of the essays in the report. Civic learning pertains to the ways in which citizens learn about collective social problems and make decisions about them that reflect the duties and responsibilities of citizenship. Such learning can occur in many social settings in everyday life, and it can also be facilitated through participation in the processes of democratic governance on many levels. Civic learning is not doctrinaire and is compatible with a range of public goals and policies. It is an activity that increases what might be called the democratic capability of a people. (shrink)

Multiple gestations, or multifetal pregnancies,raise a number of significant policy questionsconcerning the well being of women and the wellbeing of the children fetuses might become.Important questions for feminists pertain notonly to multifetal pregnancy itself, but alsoto the medical interventions associated withthese pregnancies. In this paper, we addressthe questions of how many embryos should betransferred in assisted reproduction, how manyfetuses should remain in a multiple gestation,who should make these decisions, and the needto protect women from overexposure to exogenoushormones. Although we focus (...) on assistedreproduction in the United States, we believethat our suggestions are applicable to othercountries where the technology is comparable. (shrink)
