In What is a Law of Nature? (1983) David Armstrong promotes a theory of laws according to which laws of nature are contingent relations of necessitation between universals. The metaphysics Armstrong develops uses deterministic causal laws as paradigmatic cases of laws, but he thinks his metaphysics explicates other sorts of laws too, including probabilistic laws, like that of the half-life of radium being 1602 years. Bas van Fraassen (1987) gives seven arguments for why Armstrong’s theory of laws is incapable of (...) explicating probabilistic laws. The main thrust of the arguments is that Armstrong’s metaphysical apparatus serves to drive up the initial probability values stated by probabilistic laws. Armstrong replies .. (shrink)

This paper defends Flatland—the view that there exist neither determination nor dependence relations, and that everything is therefore fundamental—from the objection from explanatory inefficacy. According to that objection, Flatland is unattractive because it is unable to explain either the appearance as of there being determination relations, or the appearance as of there being dependence relations. We show how the Flatlander can meet the first challenge by offering four strategies—reducing, eliminating, untangling and omnizing—which, jointly, explain the appearance as of determination relations (...) where no such relations obtain. Since, plausibly, dependence relations just are asymmetric determination relations, we argue that once we come mistakenly to believe that there exist determination relations, the existence of other asymmetries (conceptual and temporal) explains why it appears that there are dependence relations.

This article examines the changing scope and method of ecumenical public theology from the World Missionary Conference of 1910 until the present. Most changes were made in response to the changing ideological and political contexts. The collapse of liberalism and the social gospel was followed by a type of confessional ethics which arose directly out of the German Church Struggle. In opposition to this there emerged a realist ecumenical social ethics, much indebted to Reinhold Niebuhr, and of Ronald Preston. This (...) type of public theology and its distinctive ‘middle axiom’ method are examined and contrasted with the more recent public theologies which were influenced by liberation theology and grassroots movements. It is suggested that the ending of the Cold War and the fundamental changes that have taken place since September 11 2001 present a radically new kind of challenge to public theology. (shrink)

A very natural view about perceptual knowledge is articulated, one on which perceptual knowledge is closely related to perceptual discrimination, and which fits well with a relevant alternatives account of knowledge. It is shown that this kind of proposal faces a problem, and various options for resolving this difficulty are explored. In light of this discussion, a two-tiered relevant alternatives account of perceptual knowledge is offered which avoids the closure problem. It is further shown how this proposal can: accommodate our (...) intuitions about perceptual knowledge and perceptual discrimination in terms of the notion of primary relevance, give an account of how alternatives can be rationally excluded without appeal to perceptual discrimination in terms of the notion of secondary relevance, and deal with the problem posed by inverted Gettier cases, and hence explain what it means to rationally exclude alternatives which are of secondary relevance.

In a recent Opinion article, Sui and Humphreys [1] argue that experimental findings suggest self is ‘special’, in that self-reference serves a binding function within human cognitive economy. Contrasting their view with other functionalist positions, chiefly Dennett's [2], they deny that self is a convenient fiction and adduce findings to show that a ‘core self representation’ serves as an ‘integrative glue’ helping to bind distinct types of information as well as distinct stages of psycho- logical processing. In other words, where (...) Dennett regards self as analogous to a center of gravity, a simplification posited by observers, Sui and Humphreys regard self as a function that modulates mental processes. In practice, however, the concept of ‘self’ they employ is not unlike Dennett's. We side with Sui and Humphreys in hold- ing that self-reference modulates mental processes: reference to self during a task can bind memory to source, increase perceptual integration, and link attention to decision making, among other things. What is more, these functions are not reducible to other factors such as semantic coding, familiarity, or reward [3]. But whereas Sui and Humphreys contribute important empirical detail, the binding functions they describe are compatible with Dennett's version of functionalism, which treats self as an artifact of social process.

Christian thought on the resolution of conflicts rests on a strong predisposition against violence and a determination to discourage outbreaks of violence, limit the means used, and bring the conflict to as speedy an end as possible. Less attention has been given to the psychological and social roots of violence, the moments of transition from violence to diplomacy and reconciliation, and alternative ways of conflict resolution. These three areas are explored with special reference to the use of sanctions, the WCC’s (...) Programme to Overcome Violence, the Truth and Reconciliation Commission in South Africa, Gandhian Satyagraha, and the Northern Ireland Peace Process. Such measures should be judged against the same criteria as are used in relation to violence and war. (shrink)

In a previous paper (Duncan, T.L., Semura, J.S. in Entropy 6:21, 2004) we considered the question, “What underlying property of nature is responsible for the second law?” A simple answer can be stated in terms of information: The fundamental loss of information gives rise to the second law. This line of thinking highlights the existence of two independent but coupled sets of laws: Information dynamics and energy dynamics. The distinction helps shed light on certain foundational questions in statistical mechanics. (...) For example, the confusion surrounding previous “derivations” of the second law from energy dynamics can be resolved by noting that such derivations incorporate one or more assumptions that correspond to the loss of information. In this paper we further develop and explore the perspective in which the second law is fundamentally a law of information dynamics. (shrink)

Wright (In Gendler and Hawthorne (Eds.), Conceivability and possibility, 2002) rejects some dominant responses to Kripke’s modal argument against the mind-body identity theory, and instead he proposes a new response that draws on a certain understanding of counterpossibles. This paper offers some defensive remarks on behalf of Lewis’ objection to that argument, and it argues that Wright’s proposal fails to fully accommodate the conceivability intuitions, and that it is dialectically ineffective.

Duncan, Bruce The continuing threat from Islamist terrorists, now not just in Africa or the Middle East, but virtually anywhere their appeal may reach, has shocked the world. The atrocities involve mass killing not just of military prisoners but of innocent men, women and children belonging to different faiths, including Muslims opposed to their militant practices and beliefs.

Duncan, Bruce Pope Francis sparked accusations that he is espousing Marxism in his November 2013 exhortation, The Joy of the Gospel, because of his pointed attacks on economic liberalism or neoliberalism, the ideology behind versions of free-market economics. The conservative US radio commentator, Rush Limbaugh, with a following of 20 million listeners on a program valued at $400 million, accused the Pope of sprouting 'pure Marxism', and of not knowing what he was talking about.

Duncan, Bruce Tracing the sources for the economic thinking embedded in the writings of Pope Francis is not straightforward, especially in his major documents, the apostolic exhortation Evangelii Gaudium of 2013 and the full encyclical Laudato Si': On Care for Our Common Home of 24 May 2015. Many hands were involved in drafting Francis's documents, and there were extensive consultations with experts in critical areas, going back decades. This article gives only passing reference to the critical matters of climate (...) change and sustainability, and instead concentrates on the economic aspects in the writings of Pope Francis.

Recent data show that catastrophic events during one cell cycle can cause massive genome damage producing viable clones with unstable genomes. This is in contrast with the traditional view that tumorigenesis requires a long‐term process in which mutations gradually accumulate over decades. These sudden events are likely to result in a large increase in genomic diversity within a relatively short time, providing the opportunity for selective advantages to be gained by a subset of cells within a population. This genetic diversity (...) amplification, arising from a single aberrant cell cycle, may drive a population conversion from benign to malignant. However, there is likely a period of relative genome stability during the clonal expansion of tumors – this may provide an opportunity for therapeutic intervention, especially if mechanisms that limit tolerance of aneuploidy are exploited.

The Making of British Bioethics provides the first in-depth study of how philosophers, lawyers and other 'outsiders' came to play a major role in discussing and helping to regulate issues that used to be left to doctors and scientists. It details how British bioethics emerged thanks to a dynamic interplay between sociopolitical concerns and the aims of specific professional groups and individuals who helped create the demand for outside involvement and transformed themselves into influential 'ethics experts'. Highlighting this interplay helps (...) us appreciate how issues such as embryo research and assisted dying became high-profile 'bioethical' concerns in the late twentieth century, and why different groups now play a critical role in developing regulatory standards and leading public debates. The book draws on a wide range of original sources and will be of interest to historians of medicine and science, general historians and bioethicists. (shrink)

In this article it is argued that the standard theoretical account of risk in the contemporary literature, which is cast along probabilistic lines, is flawed, in that it is unable to account for a particular kind of risk. In its place a modal account of risk is offered. Two applications of the modal account of risk are then explored. First, to epistemology, via the defence of an anti-risk condition on knowledge in place of the normal anti-luck condition. Second, to legal (...) theory, where it is shown that this account of risk can cast light on the debate regarding the extent to which a criminal justice system can countenance the possibility of wrongful convictions.
