|Logical space: is the designation by L. Wittgenstein in his Tractatus Logico-Philosophicus for a set of independent (atomic) sentences that are connected with the truth value true or false. Some of these sentences will represent facts or elements of facts. These facts can be conceived as possible worlds and localized as points in the logical space.|

Glue/Glueness/Stalnaker: forms no region in logical space. - Logical space: principle: all relations must be founded on intrinsic properties.
Def equivalence/localization/logical space/Stalnaker: saying that i is equivalent to j is to say that the localization functions i and j represent the same possible world - Def intrinsic property: Region in logical space that is invariant with respect to this equivalence relation - contrast: conventional property.
logical space/Stalnaker: does not exist independently of the individuals who inhabit it, but is abstracted from the world as we find it.
Spatial/logical/Stalnaker: Solution/Stalnaker: is our intuitions: most of us have an actualistic conception of possible world and possible individuals, but they represent a possibilism regarding spatial localization - places north and south of us are just as real - we do not need surrogates for absent objects - even if there is no world-independent identity, there is still a localization-independent one.
