Actuality, Possibility, and Worlds by Alexander R. Pruss

By Alexander R. Pruss

Reality, hazard and Worlds is an exploration of the Aristotelian account that sees percentages as grounded in causal powers. On his approach to that account, Pruss surveys a few ancient methods and argues that logicist techniques to probability are implausible.

The suggestion of attainable worlds seems to be precious for lots of reasons, resembling the research of counterfactuals or elucidating the character of propositions and houses. This usefulness of attainable worlds makes for a moment basic query: Are there any attainable worlds and, if this is the case, what are they? Are they concrete universes as David Lewis thinks, Platonic abstracta as consistent with Robert M. Adams and Alvin Plantinga, or perhaps linguistic or mathematical constructs similar to Heller thinks? Or might be Leibniz correct in pondering that possibilia are usually not on par with actualities and that abstracta can simply exist in a brain, in order that attainable worlds are rules within the brain of God?
