Martin Schulz, 29 Mar 2024}, author = {Lewis,David K.}, subject = {Possible Worlds}, note = {IV 147 Centered possible worlds/De re/de se/Quine/Lewis: (Ontological Relativity, Propositional Objects): E.g., A cat that is being chased by a dog wants to get onto the roof to be safe - de dicto: it wants a state that is the class of all possible worlds where it reaches the roof. Problem: cross-world identity: Question: which of the many counterparts in many possible worlds is the cat itself? Solution/Quine: centered world: Pairs of a world and a designated time-space point in it, the desired state is then a class of centered worlds - no centered world belongs to two classes (desired and dreaded possible worlds). >Centered world, >Counterpart/Lewis, >Counterpart relation/Lewis, >Counterpart theory/Lewis, >Identity across worlds. QuineVs: ultimately better divided theory: here are the objects of simple settings, classes of stimulus patterns that are more complex are linguistic. Property/Lewis: corresponds to a class of centered worlds, more specifically to a property of space-time points, but also a property of cats. IV 148 Possible world/Quine/Lewis: Lewis: large particulars (concrete) - Quine: abstract entities - certain classes of classes of quadruples of real numbers - (space-time points) - Stalnaker: pro Quine: corresponds better to our everyday language: What it could have been like. IV 149 Situation/Possible world/Lewis: Thesis: there can also be alternatives within a possible world - thus distinction situation/Possible world - LewisVsStalnaker: not propositions as belief objects (objects of desire) but attitudes de se - E.g. Lingens with memory loss finds out in the book that there are two people who could be identical with him - a) on the 6th floor at Stanford - b) in the basement of a different library 3km away - two possible situations (possibilities) in the same possible worlds - solution: property instead proposition - the propositions apply to both people in the same way. >Properties/Lewis, >Proposition/Lewis. --- V 42 Centering assumption/Possible world/Lewis: If it was violated, worlds that differed in a non-observed way would be considered to be the same as the actual world. V 262 Possible world/Equality/Identity/Lewis: it is an independent and difficult question whether two possible worlds that exactly match their history also match in all other aspects - e.g. in their probabilities, laws, modal truths, counterfctual conditionals. >Counterfactual conditional/Lewis. Lewis: this is not of interest here. Overall history/Supervenience: supervenes on the history of events, whatever else may in turn supervene on the overall history. >Supervenience/Lewis. --- Schwarz I 216 Possible world/Lewis: no set of ordinary sentences - of which there are not enough in the language. Lewis: counterparts, possible worlds are real (KripkeVs) (PutnamVs). --- Lewis I 59 Possible world/Lewis: you can speak pretty freely and metaphysically guileless and without special ontological reservations about possible worlds. --- II 214 Possible world save separation of object/meta languange - Truth and analyticity cannot be defined in the same language. II 214 Definition Possible World (VsLewis): The concept of a possible world can be explained even by recourse to semantic terms. Possible worlds are models of the analytical sentences of a language or diagrams or theories of such models. II 214 LewisVs: possible worlds cannot be explained by recourse to semantic terms. Possible worlds exist and should not be replaced by their linguistic representations. 1) Such a replacement does not work properly: two worlds that are indistinguishable in the representative language are (falsely) assigned one and the same representation. >ersatz world/Lewis.}, note = { Lewis I David K.
