The Possible and Other Kinds of World
The author argues that possible worlds semantics is counterintuitive and does not to achieve its goals. The definition of the meaning of a sentence as the set of all possible worlds in which the sentence is true is criticized as inadequate; the semantics of modal expressions is shown to be uninformative. Truth-conditions of counterfactuals on one hand, and definitions of law-like expressions (or statements expressing causal connection) on the other hand, are exposed as circular. A further development of indexical semantics - more fine-grained and involving interdisciplinary research into the relationships among the indices - is advocated as an alternative.
