Definition primary description: for them, the substitutability of identity (SI) applies.
Definition secondary description: for them the substitutability of identity (SI) fails.
E.g. Russell: two readings:
(1) George IV did not know whether Scott was the author of Waverley.
Description/Logical Form/Russell/Hintikka: "The Author of Waverley": (ix) A (x)
Primary: the description has the following force:
(2) (Ex)[A(x)&(y)A(y) > y = x) & George IV knew that (Scott = x).
((s) notation: the quantifier is here always a normal existence quantifier, mirrored E).
That is, the quantifier has maximum range in the primary description.
More likely, however, is the second reading:
(3) ~ George IV knew that (Ex)[A(x) & (y) > y = x & (Scott = x)].
((s) narrow range)
Range/HintikkaVsRussell: he did not know that there is a third possibility for the range of a quantifier ((s) "medium range"> Kripke,> wolf).
(4) ~ (Ex) [A(x) & (y)(A (y)> y = x) & George IV knew that (Scott = x)]._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
