Actuality/actual/possible world/Lewis: actual should be analyzed as an index word. In every world "actual" refers to this particular world. - important argument: but that does not mean that the meaning of "actual" changes in any way. - Non-rigidity: does not mean that the importance varies from possible world to possible world.
"actual": is an operator. LewisVsScepticism: "I am actual" is true in every possible world. - That we can know. - But "all worlds are actual" is wrong in every possible world.
Actual/actuality/Lewis: primary sense: refers to the possible world in which the statement is made - secondary sense: shifts the reference to the context - e.g. only primary sense: There could have been items that differ from the actual ones. - E.g. I could be richer than I really am - only a secondary meaning: E.g. the following is contingent: in the real world (actual world) Caesar was assassinated. - E.g. Alpha be the name of the actual world: alpha (without quotation marks) might also not have been the actual world.
Actual/ontology/actuality/existence/there is/Lewis: thesis: there are many things that are not actual. - E.g. an uncountable number of people, spread over many possible worlds. - LewisVsCommon sense: not everything is actual. - Difference: exists/there is._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
