Scope, range, logic, philosophy: range is a property of quantifiers or operators to be able to be applied to a larger or smaller range. For example, the necessity operator N may be at different points of a logical formula. Depending on the positioning, the resulting statement has a considerably changed meaning. E.g. great range "It is necessary that there is an object that ..." or small range "There is an object that is necessarily ....". See also quantifiers, operators, general invariability, stronger/weaker, necessity, Barcan Formula.

Range: problem with descriptions, not with names - E.g. it is (logically) chronologically possible that Caesar was the father of Brutus - description: Caesar = man who not begat Brutus - then: narrow scope: logical impossibility; the whole sentence is wrong - long scope: someone who is described among other things as non-producer of Brutus ... the sentence remains true.
