Standard semantics/modal logic/Hintikka: Problem: the alternative worlds must be formed from the same individual domain and also from the same domain of predicates (basic term).
That is, the individuals must all already exist!
Definition scenario/Hintikka: a scenario is everything that is compatible with the knowledge of a knowing person b. We can also call it b's worlds of knowledge.
Definition relevant world/Hintikka: relevant worlds are all those which are compatible with the knowledge of a person considered here.
Definition qualitative/terminology/Hintikka: terminology corresponds to a yes-no distinction. - Contrast: the contrast is comparative.
Definition Desideratum/Hintikka: the desideratum is the piece of information that provides a complete answer to a question. E.g. (3) is the desideratum of (2).
(2) Who killed Roger Ackroyd?
(3) I know who killed Roger Ackroyd.
(3) can be analyzed as
(4) (Ex) I know that (x killed Ackroyd)
Where "x" is about people.
Definition conclusive/conclusive answer/Hintikka: an answer is conclusive iff. (5) implies (4), for example,
(5) I know that d has killed Ackroyd.
(4) (Ex) I know that (x killed Ackroyd).
Problem: normally the implication is valid, but it can be because "d" (on different occasions) does not refer to the same person.
Presupposition/Questions/Hintikka: the presupposition of a question is obtained by omitting the extreme epistemic operator ("I know that") from the desideratum of the question.
Definition matrix of a question/Hintikka: the matrix of a question is the presupposition obtained from the desideratum without the utmost epistemic operator.
