This collection of chapters on metaphysics and philosophy of religion is organized around the theme of hyperspace. The book contains critical discussions and evaluations of some non-theistic reasons to believe in hyperspace in Chapter 1 (e.g., reasons arising from reflection on incongruent counterparts and fine-tuning arguments), of some theistic reasons in Chapter 7 (e.g., reasons arising from reflection on puzzles known as the problem of the best and the problem of evil), and of some distinctively Christian reasons in Chapter 8 (e.g., reasons arising from reflection on traditional Christian themes such as heaven and hell, the Garden of Eden, angels and demons, and new testament miracles). In the intervening chapters, the book provides critical discussions of a variety of puzzles in the metaphysics of material objects that are either generated by the hypothesis of hyperspace (e.g., the topics of mirror determinism and mirror incompatibilism) or else informed by the hypothesis of hyperspace (e.g., theories of receptacles, boundaries, contact, the four-color theorem, location and occupation relations, extended mereological simples, and superluminal motion).
