M.J. Cresswell on Accessibility - Dictionary of Arguments
Hughes I 67f Accessibility/possible worlds/Hughes/Cresswell: many authors: From conceivability or imaginability. >Conceivability. E.g. game: the visibility relation between players. - Invisible worlds are not taken into account. Conceivability of worlds is always considered from the actual world: corresponding system T. >Actual world, cf. >Actuality. Necessity/T: Truth in a selected set of worlds. System T: necessity: only considers worlds that we can imagine. System S4: Transitivity of conceivability: what could be conceivable in other worlds. - (i.e. conceivable in a possible world, which in turn can be imagined from the actual world). - Then we have another necessity: truth in all worlds. System S5: all are visible to all, not a question of imagination._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
