The fact that two descriptions mean a single object may be discovered only in the course of an investigation._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Self-identity/(s)>Schmidentity/Identity/Field: true identity is only self-identity. - It is not enough when the extensions of the other predicates (other than "is identical to") are up for grabs.
Less than true identity: E.g. congruence: - is an equivalence relation for which substitutivity applies.
Identity/Quine: it is not easy to say which facts about us make it, that "is identical to" and "rabbit" stands for rabbits - and not "belong together" or "are of the same". - And by analogy for temporary stages - inflationism: can in turn accept facts. - (FieldVsinflationism)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
