|Identity: Two objects are never identical. Identity is a single object, to which may be referred to with two different terms. The fact that two descriptions mean a single object may be discovered only in the course of an investigation.|

Definition Identificatio/Goodman: based on the division into entities and kinds. - The answer to the question: "The same or not the same?" always has to be: "The same what?".
(16) In the relevant correct system each point correlates with a combination of a vertical and a horizontal line.
(17) In the (one other) corresponding correct system no point correlates with a combination of any other elements.
Moreover, since the isomorphism neither guarantees identity nor excludes it (although it is guaranteed by it), means (16) no positive or negative determination on something other than straight lines, and combinations of straight lines, while (17) does not determine itself on anything except to points.
(14) Each point is generated by a vertical and a horizontal straight line.
(15) No dot is formed by straight lines or something else.
Are (14) and (15) about the same points? Is the screen on which a spot moves the same as the one on which no spot moves? Is the seen table the same as the pile of molecules?
Goodman: The answer to such frequently asked questions in philosophy is a strong Yes and a strong No. The realist will oppose the conclusion that there is no world. The idealist will oppose the conclusion that conflicting versions describe different worlds. Goodman: both views are appealing. Finally, the difference between them is purely conventional!

Individuation/Quine:> individuation is defined by a bundle mutually interrelated grammatical particles and constructions. Plurals, pronouns, numerals, the "is" (the identity) and the from them derived "same" and "another".
GoodmanVsQuine: he failed to explain that the interpretation of these particles cannot be made without consideration of the thing places they individuate. The interpretation changes when they are used in different systems.
There is no way to individuate a world, except with the help of a version.
