| Russell, B. | Hintikka Vs Russell, B. | II 165 On Denoting/Russell/Hintikka: (Russell 1905) Problem: with phrases that stand for genuine constituents of propositions. Problem/Frege: failure of substitutivity of identity (SI) in intensional contexts. Informative Identity/Frege: the fact that identity can even sometimes be informative is connected to this. EG/Existential Generalization/Russell: it, too, may fail in in intensional contexts, (problem of empty terms). HintikkaVsRussell: he does not recognize the depth of the problem and rather circumvents the problems of denoting terms. E.g. The bald king of France/Russell: Problem: we cannot prove by existential generalization that there is a present king of France. HintikkaVsRussell: But there are also other problems. (see below for ambiguity of cross world identificaiton). Description/Russell/Hintikka: Def Primary Description: the substitutivity of identity applies to them (SI) Def secondary description: for them, substitutivity of identity (SI) fails. II 166 Existential Generalization/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) primarily: the description has the following power: (2) (Ex)[A(x) & (y) A(y) > y = x) & ~ George IV knew that (Scott = x)]. ((s) notation: quantifier here always normal existential quantifier, mirrored E). I.e. the quantifier has the maximum range in the primary identification. The second reading is more likely, however: Secondary: (3) ~George IV knew that (Ex)[A(x) & (y)(A(y) > y = x & (Scott = x)]. ((s) narrow range): Range/HintikkaVsRussell: he did not know that there is also a third option for the range of a quantifier ((s) >"medium range"/Kripke). (4) ~(Ex)[A(x) & (y)(A(y) > y = x ) & George IV knew that (Scott = x)]. II 166 Existential Generalization/HintikkaVsRussell: he did not see that there was a reason for the failure of the existential generalization, which is not caused by the non-existence of the object. E.g. (5) George IV knew that the author of Waverley is the author of Waverley. a) trivial interpretation: I 167 (6) George IV knew that (Ex)(A(x) & (y)(A(y) > y = x)) everyday language translation: he knew that one and only one person wrote Waverley. I 166 b) non-trivial interpretation: (7) (Ex)(A(x) & (y)(A(y) > y = x) & George IV knew that (A(x) & (y)(A(y) > y = x))). ((s) no quantifier after "knew that everyday language translation: George knew of the only person who actually wrote Waverley, that they did. Because knowledge implies truth, (7) is equivalent to (8) (Ex) George IV knew that (Ez)(A(z) & (y)(A(y) > y = z) & x = z). this is equivalent to. (9) (Ex) George IV knew that (the author of Waverley = x) Here, the description has secondary (narrow) range. Everyday language translation: George knew who the author of Waverley is. I 167 Knowledge/Who/What/Where/HintikkaVsRussell: Russell cannot explicitly analyze structures of the form knows + W-sentence. General: (10) a knows, who (Ex x) is so that A(x) becomes (11) (Ex) a knows that A(x). Hintikka: this is only possible if we modify Russell’s approach: Problem: the existential generalization now collapses in a way that cannot be attributed to non-existence, and which cannot be analyzed by Russell’s Theory of Descriptions (ThoD). Problem: for every person, there are a lot of people whose names they know and of whose existence they know, but of who they do not know who they are. II 168 E.g. Charles Dodgson was for Queen Victoria someone of whom she had heard, but whom she did not know. Problem: if we assume that (11) is the correct analysis of (10), the following applies. (12) ~(Ex) Victoria knew that Dodgson = x) But that’s trivially false, even according to Russell. Because the following is certainly true: (13) Victoria knew that Dodgson = Dodgson) Existential Generalization/EG: then yields (14) (Ex) Victoria knew that Dodgson = x) So exactly the negation of (12) contradiction. II 168 Descriptions/Hintikka: are not involved here. Therefore, Russell’s description theory cannot help here, either. E.g. we can also assume that Victoria knew of the existence of Dodgson. Empty Terms/Empty Names: are therefore not the problem, either. Ontology/Hintikka: so our problem gets an ontological aspect. Existential Generalization/EG/Being/Quine/Ontology/Hintikka: the question of whether existential generalization may be applied on a singular term "b", E.g. in a context "F(b)", is the same as whether b may be value of a bound variable. Existential Generalization/Hintikka: does not fail here because of non-existence. II 169 We are dealing with the following problems here: Manifestation used by a) no SI Frege, Russell b) no EG (i) due to non-existence Russell (ii) because of ambiguity Hintikka Ambiguity/Solution/Hintikka: possible worlds semantics. E.g. (12) - (14) the problem is not that Dodgson did not exist in the actual world or not in one of Victoria’s worlds of knowledge, but that the name Dodgson singles out different individuals in different possible worlds. Hence (14) does not follow from (13). II 170 Existential Generalization/EG/Ambiguity/Clarity/Russell/Hintikka: Which way would have been open to Russell?. Knowing-Who/Russell/Hintikka: Russell himself very often speaks of the equivalence of knowledge, who did something with the existence of another individual, which is known to have done... + ... II 173 Denotation/Russell/Hintikka: Important argument: an ingenious feature of Russell’s theory of denotation from 1905 is that it is the quantifiers that denote! Theory of Denotation/Russell: (end of "On Denoting") includes the reduction of descriptions to objects of acquaintance. II 174 Hintikka: this relation is amazing, it also seems to be circular to allow only objects of acquaintance. Solution: We need to see what successfully denoting expressions (phrases) actually denote: they precisely denote objects of acquaintance. Ambiguity/Clarity/Hintikka: it is precisely ambiguity that leads to the failure of the existential generalization. Existential Generalization/Waverley/Russell/Hintikka: his own example shows that only objects of acquaintance are allowed: "the author of Waverley" in (1) is in fact a primary incident i.e. his example (2). "Whether"/Russell/Hintikka: only difference: wanted to know "if" instead of "did not know". (secondary?). Secondary Description/Russell: can also be expressed like this: that George wanted to know of the man who actually wrote Waverley whether he was Scott. II 175 That would be the case if George IV had seen Scott (in the distance) and had asked "Is that Scott?". HintikkaVsRussell: why does Russell select an example with a perceptually known individual? Do we not usually deal with beings of flesh and blood whose identity is known to us, instead of only with objects of perception?. Knowing Who/Knowing What/Perception Object/Russell/Hintikka: precisely with perception objects it seems as if the kind of clarity that we need for a knowing-who, is not just given. Identifcation/Possible Worlds Semantics/HintikkaVsRussell/Hintikka: in my approach Dodgson is a bona fide individual iff. he is one and the same individual in all worlds of knowledge of Victoria. I.e. identifiable iff. (15) (E.g.) in all relevant possible worlds it is true that (Dodgson = x). Problem: What are the relevant possible worlds?. II 178 Quantifier/Quantification/HintikkaVsRussell: Russell systematically confuses two types of quantifiers. (a) of acquaintance, b) of description). Problem: Russell has not realized that the difference cannot be defined solely in terms of the actual world!. Solution/Hintikka: we need a relativization to sets of possible worlds that change with the different propositional attitudes. II 179 RussellVsHintikka: he would not have accepted my representation of his position like this. HintikkaVsRussell: but the reason for this merely lies in a further error of Russell’s: I have not attributed to him what he believed, but what he should have believed. Quantification/Russell/Hintikka: he should have reduced to objects of acquaintance. Russell believed, however, it was sufficient to eliminate expressions that seemingly denote objects that are not such of acquaintance. Important argument: in that his quantifiers do not enter any ontological commitment. Only denoting expressions do that. Variable/Russell/Hintikka: are only notational patterns in Russell. Ontological Commitment/Quine/HintikkaVsRussell: Russell did not recognize the ontological commitment that 1st order languages bring with them. Being/Ontology/Quine: "Being means being value of a bound variable". HintikkaVsRussell: he has realized that. II 180 Elimination/Eliminability/HintikkaVsRussell/Hintikka: in order to eliminate merely seemingly denoting descriptions one must assume that the quantifiers and bound variables go over individuals that are identified by way of description. ((s) Object of the >Description). Otherwise, the real Bismarck would not be a permissible value of the variables with which we express that there is an individual of a certain species. Problem: then these quantifiers may not be constituents of propositions, because their value ranges do not only consist of objects of acquaintance. Therefore, Russell’s mistake was twofold. Quantifier/Variable/Russell/Hintikka, 1905, he had already stopped thinking that quantifiers and bound variables are real constituents of propositions. Def Pseudo Variable/Russell/Hintikka: = bound variable. Acquaintance/Russell: values of the variable should only be objects of acquaintance. (HintikkaVsRussell). Quantifiers/HintikkaVsRussell: now we can see why Russell did not differentiate between different quantifiers (acquaintance/description): For him quantifiers were only notational patterns, and for them the range of possible interpretations need not be determined, therefore it makes no difference if the rage changes!. Quantification/Russell: for him, it was implicitly objectional (referential), and in any event not substitutional. Peacocke I 190 Possible Worlds/Quantification/HintikkaVsRussell: R. is unable to explain the cases in which we quantify in belief contexts (!) where (according to Hintikka) the quantifier over "publicly descriptively identified" particulars is sufficient. Hintikka: compares with a "roman à clef". Peacocke: it is not clear that (whether) this could not be explained by Russell as cases of general ideas, so that the person with such and such characteristics is so and so. Universals/Acquaintance/Russell/Peacocke: we are familiar with universals and they are constituents of our thoughts. HintikkaVsRussell: this is a desperate remedy to save the principle of acquaintance. PeacockeVsRussell: his arguments are also very weak. Russell: E.g. we cannot understand the transitivity of "before" if we are not acquainted with "before", and even less what it means that one thing is before another. While the judgment depends on a consciousness of a complex, whose analysis we do not understand if we do not understand the terms used. I 191 PeacockeVsRussell: what kind of relationship should exist between subject and universal?. Solution: the reformulated PB: Here we can see to which conditions a term is subject, similar to the principle of sensitivity in relational givenness. I 192 HintikkaVsRussell: ("On denoting what?", 1981, p.167 ff): the elimination of objects with which the subject is not familiar from the singular term position is not sufficient for the irreducibility of acquaintance that Russell had in mind. Quantification/Hintikka: the quantifiers will still reach over objects with which the subject is not familiar. But such quantifiers cannot be constituents of propositions, if that is to be compatible with the PB. Because they would certainly occur through their value range Occur and these do not consist of particulars with which one is familiar. |
