Leibniz Principle/Identity/Cresswell:
a) metaphysical (uncontroversial): indistinguishability
b) linguistically: substitutability.
>Indistinguishability, >Substitution.
Problem: in the context of reference: are descriptions real qualifying words?
>Reference, >Descriptions, >Designation.
Indefinite description: no one believes that it is referring.
Exception:
Epsilon Operator/Hilbert: εxF (x): "an x such that F (x)".
Indefinite description: here the Leibniz-Principle does not apply.
((s) Explanation: Example mathematics: √4: +2 or -2. These are not indistinguishable).},
