[Figure: see text] Quantum mechanics has recently indicated that temporal order is not always fixed, a finding that has far-reaching philosophical and theological implications. The phenomena, termed “indefinite causal order,” shows that events can be in a superposition with regard to their order. In the experimental setting with which this article is concerned, two events, A and B, were shown to be in the ordering relations “A before B” and “B before A” at the same time. This article introduces an ongoing project that seeks to make sense of this result, with a particular focus on the methodology by which this research will be undertaken. Specific research questions, particularly regarding what indefinite causal order might mean for the metaphysics of time and the doctrine of salvation, are introduced. The collaborative approach detailed brings together the disciplinary skills of a working scientist and a working theologian. What is offered is a collaborative methodology for interaction between science and religion that is more than the sum of its parts. Alister McGrath’s idea of multiple rationalities is employed as an epistemological framework within which this research takes place. Within an epistemologically pluralistic model, collaborative efforts are not only encouraged but necessary. Complex reality requires an equally complex, usually interdisciplinary, explanation. I argue that such dialogue is both theologically justified and culturally valuable and indicates the direction in which this research will be taken.

Quantum mechanics has recently indicated that, at the fundamental level, temporal order is not fixed. This phenomenon, termed Indefinite Causal Order, is yet to receive metaphysical or theological engagement. We examine Indefinite Causal Order, particularly as it emerges in a 2018 photonic experiment. In this experiment, two operations A and B were shown to be in a superposition with regard to their causal order. Essentially, time, intuitively understood as fixed, flowing, and fundamental, becomes fuzzy. We argue that if Indefinite Causal Order is true, this is good evidence in favor of a B‐theory of time, though such a B‐theory requires modification. We then turn to theology, suggesting that a B‐theoretic temporal ontology invites serious reconsideration of the doctrine of salvation. This paper concludes that the best explanation for salvation given a B‐theory is mind‐dependent salvific becoming, a type of psychological soteriological change that occurs through downward causation.
The main idea consists in researching the existence of certain characteristics of nature similar to human reasonability and purposeful actions, originating and rigorously inferable from the postulates of quantum mechanics as well as from those of special and general relativity. The pathway of the “free-will theorems” proved by Conway and Kochen in 2006 and 2009 is followed and pioneered further. Those natural reasonability and teleology are identified as a special subject called “God” and studyable by “quantum theology”, a scientific counterpart of classical theology as far as the latter endeavors to justify rationally God (without quotation marks) postulated by religion, but meaning in the present study, first of all, Christianity. The suggested “quantum theology” is situated in the historical opposition and conflict of science and religion in Modernity and its reflection in Heidegger’s conception of “ontotheology”. The conception of “ontomathematics” introduced in previous papers to unite and unify physics, mathematics, and philosophy is reinterpreted in the present context to be conservatively generalized in a way to include “quantum theology”. Two conceptions, “locality” and “nonlocality”, originating initially from physics and especially, from theory of entanglement and quantum information, are also generalized ontomathematically, and thus in relation to the newly introduced “quantum theology”. The “quantum theology” subject of “God” is juxtaposed with God of religion and billions of believers all over the world. Husserl’s conception of “philosophy as a rigorous science” is considered to be generalized now to theology as quantum theology, particularly by the phenomenon (in the sense of his “phenomenology”) of “God”, or by an “epoché” to whether God exists or not. The research of the phenomenon of “God” is extended to the conception of the “totality” being inherent for philosophy, especially for classical German philosophy preceding Husserl’s phenomenology. Those sequences for philosophy implied by the introduction of quantum theology are investigated further, on the pathway of ontomathematics, also in relation to what “God” should mean for today’s physics and mathematics. The option and research field of “experimental quantum theology” is discussed as a direct corollary from quantum theology though being sacrilegious as for classical theology. The concluding section reflects in a more loose way on the relation of “God” for quantum theology to God for religion and billions of believers all over the world.

A recent development in the understanding of conceptual foundations of quantum theory is discussed, giving particular attention to the analysis of the so called Schroedinger’s cat paradox. The solution of this problem in the frameworks of Everett-Wheeler many-worlds interpretation of quantum mechanics is considered, as well as the philosophical and theological consequences following from this interpretation. The recommendations are given, concerning the use of questions related with conceptual foundations of quantum theory in the education when introducing students and senior class pupils in problems of the dialogue between science and religion. \nKEY WORDS: science, religion, dialogue, foundations of quantum theory, many-worlds interpretation
Classically, the causal order of two timelike separated events A and B is fixed-either A before B or B before A. This is no longer true in quantum theory, where it is possible to encounter superpositions of causal orders. The quantum switch is one of the most prominent processes with indefinite causal order. Optical realizations of the quantum switch have been successfully implemented in experiments, but some argue that this merely simulates a process with indefinite causal order and that a superposition of spacetime metrics is required for a true realization. Here, we provide a relativistic definition of causal order between operationally defined events that defines a meaningful observable in both the general relativistic and quantum mechanical sense. Importantly, this observable does not distinguish between the indefinite causal order implemented on an optical bench and the gravitational quantum switch, a gedanken experiment where the indefinite causal order is achieved by a quantum superposition of gravitational fields. Therefore, our results support the thesis that the optical quantum switch is just as much a realization of indefinite causal order as its gravitational counterpart, which makes use of the quantum mechanical behavior of spacetime.
This issue of Zygon: Journal of Religion and Science offers a podium for deep reflection on the state-of-play in “quantum theology”: theological reflection that is related to the physical theory of quantum mechanics. The thematic section has been guest edited by Mark Harris. His opening article—which in its introductory section also refers to all the other articles in the section—highlights that theological engagement with quantum physics has been dominated by the so-called “Copenhagen interpretation”; he argues for a commitment to “quantum fundamentalism,” which resolves some enduring ontological problems and takes quantum theology “beyond Copenhagen.” Shaun Henson, in dealing with Everett's “Many-Worlds Interpretation,” focuses on the status of scientific terms; he shows that the extent to which belief in Many-Worlds (which is metaphysically challenging) is believable depends on several dynamic socially oriented categories. Emily Qureshi-Hurst addresses some implications of the Many-Worlds Interpretation that are particularly relevant to theism; she argues that taking seriously the radical consequences of this interpretation means facing at least three major worries for theism pertaining to personal identity, the problem of evil, and salvation. Elise Crull offers what she calls an “interpretation-neutral yet realist” stance towards quantum mechanics; she illustrates how her interpretation-neutral take on quantum mechanics that includes the notion of “decoherence” can helpfully reframe accounts of divine action. Wilson Poon and Tom McLeish warn that one should be cautious in claiming distinctiveness for quantum theologizing (versus, for instance, theologizing classical statistical mechanics); they posit that both quantum mechanics and classical statistical mechanics point to “theology of science in which scientists participate in the divine gaze on creation as imago Dei.” And Ernest Simmons utilizes the concept of quantum decoherence, augmented by the novel theory of quantum Darwinism, to understand the transition from the quantum to the classical worlds; from his reading of quantum biology, he distills some theological metaphors for articulating divine presence at the level of life in theistic evolution. This issue also contains four articles from the 67th Annual Summer Conference of the Institute on Religion in an Age of Science (IRAS), entitled “‘We’ & ‘They’: Cross-Cultural Conversations on Identity,” which was held at Star Island, NH, USA from June 26 to July 3, 2022. Anindita Balslev highlights in her article why cross-cultural conversation is important; that conversation has the potential to give a new direction to the dynamics between “the self and the other.” CJ Love argues in her article that unraveling the complex notion of “self” and “other” necessitates a layered approach that explores genetics, phenomenology, and religion; she emphasizes the need for forming a holistic picture of body, mind, event, memory, and morality. Andrew Newberg expands in his article on the role of the brain and the biological basis of the self; he argues that the self and self-consciousness is one of the most mysterious aspects of the human being, but also that to some degree we are trapped within our brain and our consciousness, which represent our own identity. And Calvin Chatlos, in his article, applies his “Framework of Spirituality” to the identity of adolescents; he makes clear that an alternative approach to adolescent development is needed that does not reinforce a fundamental experiential separateness of “me” and “other,” but that instead promotes a spiritual transformation process that is inclusive of the “other.” The Articles section contains four articles. In the first article, Gabriel Fernandez-Borsot contributes to philosophical reflection on the role of technology in society, particularly on the intersections between spirituality and technology; in his analysis, spirituality appears as an essential dimension to cultivate in technological societies, while he argues that technology might actually reveal spirituality as richer and deeper than has been apparent in traditional settings. In the second article, Yong Sup Song and Robert Geraci study the interactions between spirituality and technology in the specific context of Korea; they consider the themes of marginalization and transcendence in transhumanism and minjung theology and reflect on the exclusion of some from the benefits of technological society and on living in the context of multiple dimensions of oppression. In the third article, Kevin Ndereba addresses the nonreligious identity formation among male Kenyan Youth, which is increasingly common; he shows how youth social groups provide spaces for wrestling with the intellectual questions raised by religious faiths and argues that nonreligious communities could benefit from moving beyond the usual caricature of strong incompatibilism that is part of popular atheist literature. Finally, in the fourth article, Eugenia Torrance revisits Newton's theology by questioning whether he promulgated a “God of the gaps” argument; she thinks that he did not and uses some of his letters and drafts to suggest that any gaps in mechanical were filled by Newton with nonmechanical natural causes and argues that Newton wanted readers to marvel at humans’ inability to fully understand his scientific system. The Articles section is followed by a reflection from Josh Reeves on Peter Harrison's “After Science and Religion” project, to which Peter Harrison offers a response. The issue ends with a book review. Ron Cole-Turner reviews Victoria Lorrimar's Human Technological Enhancement and Theological Anthropology.
