Philosophy of Physics Seminar (Thursday - Week 7, MT21)

This paper sets out, in more detail than has hitherto been achieved, some philosophical and theological implications of Hugh Everett III’s Many Worlds Interpretation of Quantum Mechanics. In particular, this paper is concerned with personal identity, the problem of evil, and the Christian doctrine of salvation. Theological engagement with Quantum Mechanics has been dominated by the Copenhagen interpretation, leaving a significant gap in the literature with regards to other interpretations. As the Many Worlds Interpretation’s credibility grows, it is imperative that metaphysicians and theologians engage with its ideas and explore its implications. This paper does just that. It argues that this fascinating interpretation of Quantum Mechanics and its seemingly radical implications must be taken seriously, and that taking these seriously means facing at least three major worries pertaining to personal identity, the problem of evil, and salvation. The paper concludes by calling philosophers and theologians to address these worries, in order that these matters of theological importance remain both credible and coherent if Many Worlds turns out to be correct.
