A Reaction

In informal contexts there might be problems with the notion of what is 'admissible'. Is 'my least favourite physical object' admissible?

The 20 ideas with the same theme [two objects turning out to be one object]:

15847 Two things relate either as same or different, or part of a whole, or the whole of the part [Plato]
15825 Carneades denied the transitivity of identity [Carneades, by Chisholm]
9853 Identity between objects is not a consequence of identity, but part of what 'identity' means [Frege, by Dummett]

9905 Identity statements make sense only if there are possible individuating conditions [Benacerraf]
16224 There can't be vague identity; a and b must differ, since a, unlike b, is only vaguely the same as b [Evans, by PG]
16521 A is necessarily A, so if B is A, then B is also necessarily A [Wiggins]
14073 Claims on contingent identity seem to violate Leibniz's Law [Gibbard]

6047 All identity is necessary, though identity statements can be contingently true [McGinn]
5494 'Lightning is electric discharge' and 'Phosphorus is Venus' are synthetic a posteriori identities [Lycan]
15074 We would understand identity between objects, even if their existence was impossible [Fine,K]
16027 If two things are equal, each side involves a necessity, so the equality is necessary [Gallois]
16231 Occasional Identity: two objects can be identical at one time, and different at others [Gallois, by Hawley]
14081 Identities can be true despite indeterminate reference, if true under all interpretations [Schaffer,J]
16360 Identity statements are informative if they link separate mental files [Recanati]
14477 Identical entities must be of the same category, and meet the criteria for the category [Thomasson]
14476 Identity claims between objects are only well-formed if the categories are specified [Thomasson]
