Why Don't I Like Possible Worlds
Languages of publication
The author argues that possible worlds semantics is counterintuitive and fails to achieve its goals. The definition of the meaning of a sentence as the set of possible worlds in which the sentence is true is criticized as inadequate; the semantics of modal expressions is claimed uninformative. Truth-conditions of counterfactuals on one hand, and definitions of law-like expressions (or statements expressing causal connection) on the other hand, are regarded as circular. A further development of indexical semantics - a more fine-grained one, involving interdisciplinary research into the relations among the indices - is advocated as an alternative.
