Intentionality/Hintikka: thesis: intentionality has a multi-world character.
Def intentional/Hintikka: a concept is intentional iff. its semantic explanation involves several possible scenarios and their relation to each other. This places intentionality close to intensionality.
>
Intensionality.
Thesis: intentionality is a gradual matter. There are types and dimensions of intentionality that are not all equally interesting. Just as possible worlds can differ.
Chisholm/Hintikka: Chisholm has proved intentionality in the logical behavior of certain concepts.

Def intentional/intentionality/Hintikka: thesis: it is a sign of intentionality when possible worlds are used to explain the semantics of the concept.
>
Possible worlds.
Intentionality/Hintikka: we can also call it intensionality:
One has to look at a background of alternatives (unrealized possibilities) when one considers the consciousness of a subject.
Intentionality/Brentano/Husserl/Hintikka: for the two, "directedness at an object" was essential for intentionality. An intentional term "points behind itself". HintikkaVsHusserl/HintikkaVsBrentano.
William Kneale: ditto.
KnealeVsHusserl/KnealeVsBrentano.

Intentionality/Hintikka: intentionality is a gradual matter. This is obvious if it is true that we always have to look at unrealized possibilities when it comes to intentionality.
"Ontological Power"/Hintikka: the greater the ontological power of a mind, the more one can go beyond the actual world.
Degree of Intentionality/Hintikka: the degree of intentionality is measured by the distance to the actual world.

Condition c: "What is, is necessary what it is and no other thing."
Intentionality/Hintikka: that the failure of (c) (preservation of identity, VsSeparation) is a criterion for them, can be seen in their behavior in changing concepts: necessity (logical, physical, and analytical) satisfies condition c). ("What is, is necessary what it is and no other thing".)
Conversely, certain other concepts are obviously more intentional than necessity, and they violate c).
>
Logical necessity, >
Analytical necessity.

E.g. "Not everything what is, is so that it is known what it is, nor that it is no other thing".
