The best arguments for possible worlds. as states of affairs furnish us with equally good arguments for impossible worlds of the same sort. I argue for a theory of impossible worlds on which the impossible worlds correspond to maximal inconsistent classes of propositions. Three objections are rejected. In the final part of the paper, I present a menu of impossible worlds and explore some of the...

In standard possible worlds semantics, propositions are sets of possible worlds. To believe a proposition is to believe that your world is one of the worlds in that set. So the proposition that there are extraterrestrials is the set of worlds in which there are extraterrestrials, and to believe that there are extraterrestrials is to believe that your world is a member of that set. A belief in a...

Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn’t have been instantiated. These views motivate Stalnaker’s ‘‘two dimensional’’ account of the necessary a posteriori on which there is no single propo...

The purpose of this study was to understand why organizational adoption of virtual worlds much has been much slower than expected, by empirically identifying factors that influence organizational intent to adopt virtual worlds. To do so, we developed a model of factors that influence organizational adoption of virtual worlds, based on the Technology–Organization–Environment framework. The model...

Virtual worlds are three-dimensional, computer-generated worlds in which users take the form of avatars and use those avatars to interact with objects and other avatars in the virtual world. Virtual worlds are growing in importance in both educational institutions and businesses. Educational institutions have adopted virtual worlds as a medium for instructional delivery whereas businesses are u...

1 Introduction Jackson (Jackson 95) recognises the vital difference between an application's domain and its code: two different worlds, each with its own language, experts, ways of thinking etc. A finished application forms the intersection between these worlds. The difficult job of the software engineer is to build a bridge between these worlds, at the same time as solving problems in both wor...
