In fact, it seems that the two worlds are identical, except that there is a permutation of identities, that is, of counterparts. This, the anti-Haeccetist replies, is a distinction without distinction!
Now, here, all meaning of "truth" and "falsehood" is abstracted, except for their difference.
The classical view with the substitution of Bolzano produces too much: it counts conclusions as valid, which are obviously invalid.
But it also produces too little by citing arguments as invalid which should be recognized as valid in a plausible manner.
It is disputed whether the production of such a counterexample is a necessary condition for the invalidity. That is, whether the inability to produce one is sufficient for validity.
Stalnaker: includes an "impossible world" under his worlds, which he calls lambda, in which every statement is true! All such conditional sentences are found to be true here.
If the boundary (interpretation or naming) between two things is indeterminate, one is the other in an undefined way.
But if we were to protest against the introduction of a new link with the sole reason that it leads to a paradox, this objection would be entirely ad hoc. There would be no diagnosis of the problem.
Bluriness (fuzzy): does not help with Sorites - graduation distribution is no possibility distribution.
Impermissible duplication: the mythical Crete, as different from Greek Crete, the historical, the European, the remembered._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
