|Propositional knowledge, philosophy: the knowledge of whether certain propositions are true or false in contrast to a knowledge-how or possessing an ability. A problem with propositional knowledge are indexical theorems because the determination of the truth value (true or false) is context-dependent and situation-dependent here. See also propositions, opacity, example of the two omniscient Gods.|

|Frank I 16 ~
Propositional knowledge/Lewis: There are attitudes that cannot be analyzed as A about propositions: E.g. 2 Gods could know all the propositions without being able to localize themselves - Proposition/Lewis: Never with index I, he, here, now - de se: includes de dicto, but not vice versa.
Propositional knowledge/Lewis: E.g. wonder what time it is: - no propositional knowledge - he knows which world he lives in - he also knows which time-space position he occupies - solution: it is the time states of him, which wonder - a time section locates the whole insomniac enough in space and time and also in logical space - however, the time layer cannot localise itself enough in the population of time sections - it cannot attribute itself the property to lie awake at 3:49 - it is the time segment, not the person as a continuant that fails in self-ascription.
