QUANTUM PHYSICS AND THEOLOGY: JOHN POLKINGHORNE ON THOUGHT EXPERIMENTS

Abstract Thought experimentation is part of accepted scientific practice, and this makes it surprising that philosophers of science did not seriously engage with it for a very long time. The situation changed in the 1990s, resulting in a highly intriguing debate over thought experiments. Initially, the discussion focused mostly on thought experiments in physics, philosophy, and mathematics. Other disciplines have since become the subject of interest. Yet, nothing substantial has been said about the role of thought experiments in nonphilosophical theology. This paper discusses the role of thought experiments in Christian theology in comparison to their role in quantum physics, as mentioned by John Polkinghorne in Quantum Physics and Theology. We first look briefly at the history of the inquiry into thought experiments and then at Polkinghorne's remarks about the role of thought experimentation in quantum physics and Christian eschatology. To determine the actual importance of thought experiments in Christian theology a number of new examples are introduced in a third step. In the light of these examples, in a fourth step, we address the question of what it is that explains the cognitive efficacy of thought experiments in quantum physics and Christian theology.     

Normative Ethics after Pragmatic Naturalism

Philip Kitcher presents an ambitious account of pragmatic naturalism that incorporates an explanatory story of the emergence and development of ethics, a metaethical perspective on progress, and a normative stance for moral theorizing. This article contends that Kitcher's normative stance is incompatible with the explanatory and metaethical components of his project. Instead, pragmatic naturalists should endorse a normative ethics that is experimental, grounded in practice, and acutely aware of cognitive and informational limitations. In particular, the ethical project would benefit from endorsing empirical work on participatory democracy for the identification of mechanisms to guide us on deep moral conflicts.     

Moral injury and the ethics of teaching tainted legacies

Cases like that of John Howard Yoder – a pacifist theorist who perpetrated sexual violence – raise difficult questions about teaching material implicated in traumatic pasts. This paper argues that “moral injury” provides a useful framework for understanding the dynamics of teaching prominent cases of tainted legacies like Yoder's and for developing best pedagogical practices across the field of religious ethics. The moral injury framework empowers students to think critically and self‐reflectively about authority, conceptions of the good, the various stakes for different persons and communities in social issues, and the need for moral repair. It establishes the importance of professor and student preparation; propels students into the moral questioning and analysis that constitutes “ethics”; draws attention to the connections between and intersectionality of various moral problems while also attending to important moral distinctions; and affords opportunities to study individual and institutional efforts at moral repair.     

Behold the lilies: Martin Buber and the contemplation of nature1

Christians attuned to ecological and eco‐justice issues typically welcome the thought that they are called by God to protect and to serve nature, as well as to respond to the needs of the poor and the oppressed. Drawing on Martin Buber's I‐Thou and I‐It conceptuality and highlighting Jesus’ command about the lilies of the field, this article argues that Christians also are called to enter into an I‐Ens relationship with nature, that is, to behold or to contemplate, as well as to protect and to serve nature, as they continue to address ecojustice issues.     

J. S. Mill’s hedonism: activism,experientialism and eudaimonism

Many contemporary scholars defend the position that J. S. Mill was a ‘eudaimonist’, in a sense implying that he was not an ‘experiential’ hedonist. One ‘activist’ argument for this interpretation rests on the claim that Mill’s core axiological uses of ‘pleasure’ in Utilitarianism should be understood to refer to worthy or pleasurable activities rather than mental states. This paper offers a three-stage rebuttal of the activist interpretation. Firstly, in the Analysis, the Examination and the Logic, Mill explicitly identifies pleasures and pains as mental states. Secondly, if we read Mill’s core axiological uses of ‘pleasure’ in Utilitarianism along activist lines, the text’s overall coherence and intelligibility becomes even more questionable than on the traditional experientialist reading. Finally, in his discussions of Plato, Mill seems to distance himself from the axiological view that non-hedonic features of mind or character have intrinsic value in their own right. In consequence, in the small number of cases in Utilitarianism in which Mill clearly speaks of ‘pleasures’ as activities, this is best construed as a derivative usage.     

THE “RELATION” BETWEEN SCIENCE AND RELIGION IN THE PLURALISTIC LANDSCAPE OF TODAY'S WORLD

The attempt to expand the discourse of science and religion by considering the pluralistic landscape of today's world requires not only adding new voices from more religious traditions but a rethinking of the basic categories of the discourse, that is, “science,” “religion,” and the notion that the main issue to be investigated is the relationship between the two. Making use of historical studies of science and religion discourse and a case study from Indonesia, this article suggests a rethinking of the categories, including giving more attention to indigenous religions.     

Epistemic Norms and Democracy: a Response to Talisse

John Rawls argued that democracy must be justifiable to all citizens; otherwise, a democratic society is oppressive to some. In A Pragmatist Philosophy of Democracy ( 2007 ), Robert B. Talisse attempts to meet the Rawlsian challenge by drawing from Charles S. Peirce's pragmatism. This article first briefly canvasses the argument of Talisse's book and then criticizes its key premise concerning (normative) reasons for belief by offering a competing reading of Peirce's “The Fixation of Belief” ( 1877 ). It then proceeds to argue that Talisse's argument faces a dilemma: his proposal of epistemic perfectionism either is substantive and can be reasonably disagreed about or is minimal but insufficient to ground a democratic society. Consequently, it suggests that the Rawlsian challenge can only be solved by abandoning Rawls's own notion of reasonableness, and that an interesting alternative notion of reasons can be derived from Peirce's “Fixation.”     

What is the Accordion Effect?

In "Action and Responsibility,' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.' Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his critique, in his "Causing Voluntary Actions,' of a much discussed view of H. L. A. Hart and A. M. Honoré that Feinberg labels the "voluntary intervention principle.' In this essay I reflect on what the accordion effect is supposed by Feinberg to be, on differences between Feinberg's understanding of this idea and that of Donald Davidson, and on the interaction between Feinberg's discussion of the accordion effect and his critique of the voluntary intervention principle.     

Leibniz's Concept of Substance and his Reception of John Calvin's Doctrine of the Eucharist

Leibniz saw the question of the eucharist as a crucial stumbling block to the agreement between Lutherans and Calvinists. Mandated together with Daniel Ernst Jablonsky to prepare working documents for the negotiations between Hanover and Brandenburg in 1697, Leibniz carefully read through the Calvinist Confessions of faith and the works of Calvin in their 1671 edition. He made an extensive collection of excerpts from the Confessions of faith and from Calvin's Institutes all intended to show that Calvinists admitted the substantial presence of Christ's body in the eucharist. (This collection of excerpts is analysed here for the first time and compared with another little-known document, the Unvorgreiffliches Bedencken). L. had argued previously in 1691/92 that, contrary to the assertions of Pellisson-Fontanier, his own conception of substance and of Christ's presence in the eucharist was completely different from Calvin's. However, by 1697, it was clear to Leibniz that Calvin's concept of substance, which was broadly speaking Aristotelian, was never defined clearly by the reformer, and could be made to coincide with Leibniz's own notion of substance as force rather than substance in its dimensional sense. At the same time L. dissociated Ubiquitarianism (doctrine characteristic of late sixteenth century Lutheranism, which defended the dimensional presence of Christ's body in heaven and in the eucharist, by arguing that Christ in his divine nature could cause his physical body to be present in several places at the same time) from Lutheranism. He also drove a wedge between the doctrines of Zwingli and Calvin. L. thus attempted to find religious union on a common ontology and he might well have succeeded if it were not for complex political circumstances, which ultimately caused the failure of the negotiations.
