A Reaction

This seems pretty close to the idea that propositions are sets of possible worlds (though that seems to add unnecessary extra baggage). If they just picture situations, why does he mention logical space? Within the limits of possible picturing?


The 9 ideas with the same theme [propositions as sets of possible worlds]:

Pictures are possible situations in logical space [Wittgenstein]
A proposition is a set of possible worlds for which its intension delivers truth [Perry]
A proposition is a set of possible worlds where it is true [Lewis]
A proposition is a set of entire possible worlds which instantiate a particular property [Lewis]
A proposition is the property of being a possible world where it holds true [Lewis]
Propositions can't have syntactic structure if they are just sets of worlds [Lewis]
If propositions are states of affairs or sets of possible worlds, these lack truth values [Heil]
It is known that there is a cognitive loss in identifying propositions with possible worlds [Williamson]
Are there partial propositions, lacking truth value in some possible worlds? [Magidor]
