Possible worlds - definition of Possible worlds in Encyclopedia (654 words) |
 | In philosophy, the concept of possible worlds is used to interpret modal claims, claims that involve notions of possibility or necessity. |
| The explicit notion of "possible worlds" is most commonly attributed to the account of Creation in the writings of Gottfried Leibniz, but scholars have also found traces of the idea in the writings of Averroes and John Duns Scotus. |
| From this groundwork, "possible worlds" became a central part of many philosophical arguments in the 1960s and 1970s—including, most famously, the analysis of counterfactual conditionals in terms of "nearby possible worlds" developed by David Lewis and Robert Stalnaker. |
| Possible world - Wikipedia, the free encyclopedia (1213 words) |
| We note that every proposition is either true or false at any given possible world; then the modal status of a proposition is understood in terms of the worlds in which it is true and worlds in which it is false. |
| The idea of possible worlds is most commonly attributed to Gottfried Leibniz, who spoke of possible worlds as ideas in the mind of God and (in)famously used the notion to argue that our actually created world must be "the best of all possible worlds". |
| Possible worlds theory in literary studies uses concepts from possible-world logic and applies them to worlds that are created by fictional texts. |
