| Leibniz’s Principle: Leibniz's law, or identity principle, states that if in the complete descriptions of objects exactly the same properties are attributed, we are concerned with the same object. In the case of identity, it is never a matter of two or more objects, but one, for which there are often different descriptions with different choice of words. Not every description is complete, so identity does not follow from each indistinguishability. See also identity, intensions, extensions, distinguishability, indistinguishability._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Ian Hacking on Leibniz Principle - Dictionary of Arguments
Millikan I 261 Leibniz' Law/VsVs/Hacking/Millikan: (recent defense of Hacking): ...the objections do not address the fact that it could be a curved space instead of a doubling. >Leibniz Principle/Millikan. Curved Space/Hacking/Millikan: in the curved space one and the same thing appears again, it is not a doubling as in Euclidean geometry. >Space curvature. MillikanVsHacking: but that would not answer the question. I 262 But there are still two interesting possibilities: Leibniz' Law/Principle/Identity/Indistinguishability/Millikan: >Indistinguishability. 1. Symmetric world: one could argue that there is simply no fact here that decides whether space is curved or doubled. >Nonfactualism. N.B.: this would imply that Leibniz's principle is neither metaphysically nor logically necessary, and that its validity is only a question of convention. 2. Symmetric world: one could say that the example does not offer a general solution, but the assumption of a certain given symmetric world: here there would very well be a fact whether space is curved or not. A certain given space cannot be both! N.B.: then Leibniz' principle is neither metaphysically nor logically necessary. N.B.: but in this case this is not a question of convention, but a real fact! >Conventions, >Facts._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
