Actuality, Possibility, and Worlds

This is an original exploration of the philosophical arguments for and against the possibility of other worlds. "Actuality, Possibility and Worlds" is an exploration of the Aristotelian account that sees possibilities as grounded in causal powers. On his way to that account, Pruss surveys a number of historical approaches and argues that logicist approaches to possibility are implausible. The notion of possible worlds appears to be useful for many purposes, such as the analysis of counterfactuals or elucidating the nature of propositions and properties. This usefulness of possible worlds makes for a second general question: Are there any possible worlds and, if so, what are they? Are they concrete universes as David Lewis thinks, Platonic abstracta as per Robert M. Adams and Alvin Plantinga, or maybe linguistic or mathematical constructs such as Heller thinks? Or is perhaps Leibniz right in thinking that possibilia are not on par with actualities and that abstracta can only exist in a mind, so that possible worlds are ideas in the mind of God? "Continuum Studies in Philosophy of Religion" presents scholarly monographs offering cutting-edge research and debate to students and scholars in philosophy of religion. The series engages with the central questions and issues within the field, including the problem of evil, the cosmological, teleological, moral, and ontological arguments for the existence of God, divine foreknowledge, and the coherence of theism. It also incorporates volumes on the following metaphysical issues as and when they directly impact on the philosophy of religion: the existence and nature of the soul, the existence and nature of free will, natural law, the meaning of life, and science and religion.
