| Carnap, R. | Quine Vs Carnap, R. | Carnap VII 151 Intensionalist Thesis of Pragmatics/CarnapVsQuine: determining the intention is an empirical hypothesis that can be checked by observing the linguistic habits. Extensionalist Thesis/QuineVsCarnap: determining the intention is ultimately a matter of taste, the linguist is free, because it can not be verified. But then the question of truth and falsehood does not arise. Quine: the completed lexicon is ex pede Herculem i.e. we risk an error if we start at the bottom. But we can gain an advantage from it! However, if in the case of the lexicon we delay a definition of synonymy no problem arises as nothing for lexicographers that would be true or false. Carnap VII 154 Intention/Carnap: essential task: to find out which variations of a given specimen in different ways (for example, size, shape, color) are allowed in the area of the predicate. Intention: can be defined as the Range of the predicate. QuineVsCarnap: might answer that the man on the street would be unwilling to say anything about non-existent objects. Carnap VII 155 CarnapVsQuine: the tests concerning the intentions are independent of existential questions. The man on the street is very well able to understand questions related to assumed counterfactual situations. Lanz I 271 QuineVsCarnap: criticism of the distinction analytic/synthetic. This distinction was important for logical empiricism, because it allows an understanding of philosophy that assigns philosophy an independent task which is clearly distinct from that of empirical sciences! Quine undermines this assumption: the lot of concepts is not independent of their use in empirical theories! I 272 There are no conceptual truths that would be immune to the transformation of such theories. Philosophy and sciences are on one and the same continuum. --- Newen I 123 Quine/Newen: is like Carnap in the spirit of empiricism, but has modified it radically. I 124 Thought/Frege: irreducible. Thought/QuineVsFrege: seeks a reductive explanation of sentence content (like Carnap). Base/QuineVsCarnap: not individual sense data, but objectively describable stimuli. Sentence Meaning/Quine/Newen: is determined by two quantities: 1) the amount of stimuli leading to approval 2) the amount of the stimuli leading to rejection. This only applies for occasion sentences. I125 Def Cognitively Equivalent/Quine/Newen: = same meaning: two sentences if they trigger the same behavior of consent or reflection. For the entire language: if it applies to all speakers. QuineVsCarnap: sentences take precedence over words. Quine I 73 QuineVsCarnap: difference to Carnap's empirical semantics: Carnap proposes to explore meaning by asking the subject whether they would apply it under different, previously described circumstances. Advantage: opposites of terms such as "Goblin" and "Unicorn" are preserved, even if the world falls short of examples that could be so sharply distinct from each other in such a way. I 74 Quine: the stimulus meaning has the same advantage, because there are stimulus patterns that would cause consent to the question "unicorn?", but not for "Goblin?" QuineVsCarnap: Carnap's approach presumes decisions about which descriptions of imaginary states are permissible. So, e.g. "Unicorn", would be undesired in descriptions to explore the meaning of "Unicorn". Difference: Quine restricts the use of unfulfilled conditionals to the researchers, Carnap makes his researcher himself submit such judgments to the informant for evaluation. Stimulus meaning can be determined already in the first stages of radical translation, where Carnap's questionnaire is not even available yet. Quine: theory has primarily to do with records, Carnap: to do with terms. I 466 For a long time, Carnap advocated the view that the real problems of philosophy are linguistic ones. Pragmatic questions about our language behavior, not about objects. Why should this not apply to theoretical questions in general? I 467 This goes hand in hand with the analyticity concept. (§ 14) In the end, the theoretical sentences generally can only be justified pragmatically. QuineVsCarnap: How can Carnap draw a line there and claim that this does not apply for certain areas? However, we note that there is a transition from statements about objects to statements about words, for example, when we skip classes when moving from questions about the existence of unicorns to questions about the existence of points and kilometers. Through the much-used method of "semantic ascent": the transition from statements about kilometers to statements about "kilometers". From content-related to formal speech. It is the transition from speech in certain terms to talk about these concepts. It is precisely the transition of which Carnap said that it undressed philosophical questions of their deceptive appearance and made them step forward in their true form. QuineVsCarnap: this part, however, I do not accept. The semantic ascent of which I speak can be used anywhere. (Carnap: "content-related" can also be called "material".) Ex If it came down to it, the sentence "In Tasmania there are Wombats" could be paraphrased like this: ""Wombat" applies to some creatures in Tasmania." IV 404 Carnap/(Logical Particles): ("The logical structure of the world"): Thesis: it is possible in principle to reduce all concepts to the immediately given. QuineVsCarnap: that is too reductionist: Disposition concepts such as "soluble" cannot be defined like this. (Even later recognized by Carnap himself). IV 416 QuineVsCarnap: Why all these inventive reconstructions? Ultimately sense stimuli are the only thing we have. We have to determine how the image of the world is constructed from them. Why not be content with psychology? V 28 Disposition/Quine: Problem: the dependence on certain ceteris paribus clauses. Potential disturbances must be eliminated. Solution: some authors: (like Chomsky) retreat to probabilities. V 29 Carnap: instead of probability: reduction sentences seen as idealizations to which corrections are made. Carnap conceives these corrections as re-definitions, i.e. they lead to analytic sentences that are true from the meaning. QuineVsCarnap: I make no distinction between analytical and other sentences. V 30 Reflexes/Holt/Quine: those that are conditioned later are not fundamentally different from innate ones. They consist of nerve paths with reduced resistance. Quine: therefore, one can conceive disposition as this path itself! ((s) I.e. pratically physical. Precisely as physical state.) Disposition/GoodmanVsQuine: a disposition expression is a change to an eventually mechanical description and therefore circular. The mechanistic terms will ultimately be implicit disposition terms. QuineVsGoodman/QuineVsCarnap: I, unlike the two, am satisfied with a theoretical vocabulary, of which some fundamental physical predicates were initially learned with the help of dipositioned speech. (Heuristic role). VII (b) 40 But his work is still only a fragment of the whole program. His space-time-point quadruples presume a world with few movements ("laziest world"). Principle of least movement is to be the guide for the construction of a world from experience. QuineVsCarnap: he seemed not to notice that his treatment of physical objects lacked in reduction! The quadruples maximize and minimize certain overall features and with increasing experience the truth values are revised in the same sense. X 127 Logical Truth/Carnap: Thesis: only the language and not the structure of the world makes them true. Truth/Logical Truth/QuineVsCarnap: is not a purely linguistic matter. Logic/QuineVsCarnap: the two breakdowns that we have just seen are similar in form and effect: 1) The logic is true because of the language only insofar as it is trivially true because of everything. 2) The logic is inseparable from the translation only insofar as all evident is inseparable from the translation. Logic/Language/Quine: the semantic ascent seems to speak for linguistic theory. QuineVs: the predicate "true" (T predicate) already exists and helps precisely to separate logic from language by pointing to the world. Logic: While talks a lot about language, it is geared towards the world and not towards language. This is accomplished by the T predicate. X 133 We learn logic by learning language. VsCarnap: but that does not differentiate logic from other areas of everyday knowledge! XI 99 QuineVsProtocol Sentence/QuineVsCarnap/Lauener: describes private, non-public autopsychological experiences. XI 129 Intention/Carnap/Lauener: (Meaning and Necessity): attempts to introduce intentions without thereby entangling himself in metaphysics. QuineVsCarnap: you cannot take advantage of a theory without paying the ontological bill. Therefore, the assumed objects must be values of the variable. Another way would be to say that certain predicates must be true for the theory to be true. But that means that it is the objects that must be the values of variables. To every value applies a predicate or its negation. ((s) >continuous determination). XI 130 Conversely, everything to which a predicate applies is a value of a variable. Because a predicate is an open sentence. XI 138 Ontology/Carnap/Lauener: Ex "x is a thing": at a higher level of universality existence assumptions no longer refer to the world, but only to the choice of a suitable linguistic framework. QuineVsCarnap: this is merely a gradual difference. XI 142 Ontology/Carnap/Lauener: (temporarily represented): Thesis: philosophical questions are always questions about the use of language. Semantic Ascent/QuineVsCarnap: it must not be misused for evasive ontological maneuvers. XI 150 Thing/Object/Carnap/Lauener: to accept things only means choosing a certain language. It does not mean believing in these things. XI 151 CarnapVsQuine: his existence criterion (being the value of a bound variable) has no deeper meaning in as far as it only expresses a linguistic choice. QuineVsCarnap: language and theory cannot be separated like that. Science is the continuation of our daily practice. XII 69 QuineVsCarnap/QuineVsUniversal Words: it is not said what exactly is the feature for the scope. Ontological Relativity/QuineVsCarnap: cannot be enlightened by internal/external questions, universal words or universal predicates. It has nothing to do with universal predicates. The question about an absolute ontology is pointless. The fact that they make sense in terms of a framework is not because the background theory has a wider scope. Absolute Ontology/Quine: what makes it pointless, is not its universality but its circularity. Ex "What is an F?" can only be answered by recourse to another term: "An F is a G." XII 89 Epistemology/Scope/Validity/QuineVsCarnap: Hume's problem (general statements + statements about the future are uncertain if understood as about sense data or sensations) is still unsolved. Carnap/Quine: his structures would have allowed translating all sentences about the world in sense data or observation terms plus logic and set theory. XII 90 QuineVsCarnap: the mere fact that a sentence is expressed with logical, set-theoretical and observational terms does not mean that it could be proved by means of logic and set theory from observation statements. ((s) means of expression are not evidence. (inside/outside, plain, circles).) Epistemology/Quine: Important argument: wanting to equip the truths about nature with the full authority of direct experience is just as much sentenced to failure as the reduction of truths in mathematics to the potential intelligibility of elementary logic. XII 91 Carnap/QuineVsCarnap: If Carnap had successfully carried out its construction, how could he have known if it is the right one? The question would have been empty! Any one would have appeared satisfactory if only it had represented the physical contents properly. This is the rational reconstruction. Def Rational Reconstruction/Carnap/Quine: construction of physicalistic statements from observation terms, logical and set-theoretical concepts. QuineVsCarnap: Problem: if that had been successful, there would have been many such constructions and each would have appeared equally satisfactory,if only it had represented the physicalistic statements properly. But each would have been a great achievement. XII 92 QuineVsCarnap: unfortunately, the "structure" provides no reduction qua translation that would make the physicalist concepts redundant. It would not even do that if his sketch was elaborated. Problem: the point where Carnap explains how points in physical space and time are attributed sensory qualities. But that does not provide a key for the translation of scientific sentences into such that are formed of logic, set-theoretical and observation concepts. CarnapVsCarnap: later: ("Testability and Meaning", 1936): reduction propositions instead of definitions. XII 94 Empiricism/QuineVsCarnap: empiricism has 1) abandoned the attempt to deduce the truth about nature from sensory experience. With that he has made a substantial concession. 2) He has abandoned rational reconstruction, i.e. attempt to translate these truths in observation terms and logical mathematical tools. QuineVsPeirce: Suppose we meant that the meaning of a statement consists in the difference that its truth makes for the experience. Could we then not formulate in a page-long sentence in observation language any differences that might account for the truth, and could we then not see this as a translation? Problem: this description could be infinitely long, but it could also be trapped in an infinitely long axiomatization. Important argument: thus the empiricist abandons the hope that the empirical meaning of typical statements about reality could be expressed. Quine: the problem is not too high a complexity for a finite axiomatization, but holism: XII 95 Meaning/QuineVsPeirce: what normally has experience implications ("difference in the experience") only refers to theories as a whole, not to individual experience sentences. QuineVsCarnap: also the "structure" would have to be one in which the texts, into which the logical mathematical observation terms are to be translated, are entire theories and not just terms or short sentences. Rational Reconstruction/QuineVsCarnap: would be a stRange "translation": it would translate the whole (whole theories), but not the parts! Instead of "translation" we should just speak of observation bases of theories. pro Peirce: we can very well call this the meaning of empirical theories. ((s) Assigning whole theories to observations). |

| Maturana, H. | Luhmann Vs Maturana, H. | Kass. 5 Component/"component"/Maturana/LuhmannVsMaturana: stRange English: covers too much and leaves open whether the operations or the structures are meant. This may be sufficient for biology, because it does not start out so strongly from events and attributes elemental character to the chemical states and state character to the elements. Even if with a short period of time. Kass. 5 Event/System Theory/Luhmann: in the investigation of consciousness and communication the concept of event imposes itself! (Non-resolvable events). A sentence is said on a certain occasion and not again. Perception is only there in a certain moment. No "components" are necessary. Kass. 6 Structural Coupling/Maturana/Luhmann: I will vary his term a little. Maturana's concept is not precise enough with regard to the causal relationship S/U. System/Maturana: assumes that one can make two statements about a system: 1. it has an autopoietic organization. LuhmannVsMaturana: the concept of organization is unusable for us! It should be enough to say: autopoietic reproduction with great scope. 2. specific structures, depending on the type of creature (mammals, fish, etc.). Kass. 7 Observation/Maturana: life must function biologically. LuhmannVsMaturana: but in biological terms it is more difficult to see which limitations constitute the selection. There are obvious possibilities for expanding complexity. Parallel to sociology: self-fullfilling prophecies: are given into society qua communication and the society that knows how to forecast itself reacts to it. |

| 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. |

| Sciama, D. | Kanitscheider Vs Sciama, D. | Kanitscheider I 376 Mach's Principle/Sciama: it is impossible to separate gravic and inertial forces, because, equal in essence, they have the same origin. Therefore only stars can be considered as sources of inertial forces in non-inertial systems. By the way, an accelerated star has a different gravitational effect than a resting star. (Newton does not consider this yet). I 377 Due to the decrease of gravity, which is caused by the acceleration of the stars, the amount of the distant masses is much stronger with 1/r than with a r -2 law, although the total amount is weakened by the expansion. (+ I 377) Thus, 80 % of the total force comes from masses beyond the Range of the 200-inch telescope of Mt Palomar. The total force now depends on the gravitational mass density rhoG G, the expansion rate tau , which determines the gravitational Doppler effect, and on the heavy mass mG of the body itself. The value of the force results in rho G rho²mG (G²mG) x acceleration of the stars and should be equal to the inertial mass mi x acceleration of the stars (special character). I 378 According to this mi should be = G²mG. This is correct, since the newly defined mi has all the properties of an inert mass and the known proportionality of heavy and inert mass appears here as a derived theorem. Now a relation to the gravitational constant G can be established. Def Gravitational Constant: shows the strength of the gravitational interaction of two inert masses. Mach's Principle/Gravitational Constant/Sciama: if in the above formula the gravitational density G is replaced by the inertia density i, and mG/mi = G, the relationship Gi² = 1 is obtained. It is important because it expresses a high degree of connection of the universe. Gravitational constant: this quantification also explains the apparent irrelevance of the properties of stars for the inertia of matter: the universe manifests itself in both phenomena precisely where Newton's theory contains arbitrary elements: in the choice of inertial systems and gravitational constants. Theory/Sciama: should describe everything that occurs and should not allow to be possible what does not actually happen. I 380 KanitscheiderVsSciama: but cosmological applications can also be derived from any local gravitational theory. E.g. Scalar tensor theory by Jordan. Dirac: also his hypothesis of large numbers led to a new cosmological model. Almost all combinations of cosmic parameters from variable gravitational constants to different mechanisms of origin and annihilation of matter as well as a temporal variation of particle masses are conceivable! |

| Stalnaker, R. | Lewis Vs Stalnaker, R. | Read III 101/102 Stalnaker equates the probability of the conditional clauses with the conditional probability. LewisVsStalnaker: there is no statement whose probability is measured by the conditional probability! (+ III 102) According to Lewis, based on Stalnaker's assumption, the odds of drawing cards are independent. But this is obviously wrong (as opposed to throwing dice). Thus, the probability of the conditional clause cannot be measured by the conditional probability. III 108 Example from Lewis If Bizet and Verdi were compatriots, Bizet would be Italian. and If Bizet and Verdi were compatriots, Bizet wouldn't be Italian. Stalnaker: one or the other must be true. Lewis: both are wrong. (Because only subjunctive conditional sentences are not truth functional). The indicative pieces would be entirely acceptable to those who do not know their nationality. Lewis IV 149 Action/Rationality/Stalnaker: Propositions are the suitable objects of settings here. LewisVsStalnaker: it turns out that he actually needs a theory of attitudes de se. Stalnaker: the rationally acting is someone who accepts various possible rational futures. The function of the wish is simple to subdivide these different event progressions into the desired and the rejected ones. Or to provide an order or measure of alternative possibilities in terms of desirability. Belief/Stalnaker: its function is simple to determine which the relevant alternative situations may be, or to arRange them in terms of their probability under different conditions. Objects of attitude/Objects of belief/Stalnaker: are identical if and only if they are functionally equivalent, and they are only if they do not differ in any alternative possible situation. Lewis: if these alternative situations are always alternative possible worlds, as Stalnaker assumes, then this is indeed an argument for propositions. ((s) Differentiation Situation/Possible world). Situation/Possible world/Possibility/LewisVsStalnaker: I think there can also be alternatives within a single possible world! For example, Lingens now knows almost enough to identify himself. He's reduced his options to two: a) he's on the 6th floor of the Stanford Library, then he'll have to go downstairs, or b) he is in the basement of the Widener College library and must go upstairs. The books tell him that there is exactly one person with memory loss in each of these places. And he found out that he must be one of them. His consideration provides 8 possibilities: The eight cases are spread over only four types of worlds! For example, 1 and 3 do not belong to different worlds but are 3000 miles away in the same world. In order to distinguish these you need qualities again, ((s) the propositions apply equally to both memory artists.) V 145 Conditionals/Probability/Stalnaker: (1968)(1) Notation: ">" (pointed, not horseshoe!) Def Stalnaker Conditional: a conditional A > C is true if and only if the least possible change that makes A true, also makes C true. (Revision). Stalnaker: assumes that P(A > C) and P(C I A) are adjusted if A is positive. The sentences, which are true however under Stalnaker's conditions, are then exactly those that have positive probabilities under his hypothesis about probabilities of conditionals. LewisVsStalnaker: this is probably true mostly, but not in certain modal contexts, where different interpretations of a language evaluate the same sentences differently. V 148 Conditional/Stalnaker: to decide whether to believe a conditional: 1. add the antecedent to your set of beliefs, 2. make the necessary corrections for the consistency 3. decide if the consequence is true. Lewis: that's right for a Stalnaker conditional if the fake revision is done by mapping. V 148/149 LewisVsStalnaker: the passage suggests that one should pretend the kind of revision that would take place if the antecedens were actually added to the belief attitudes. But that is wrong: then conditionalisation was needed. Schwarz I 60 Counterpart/c.p./counterpart theory/c.p.th./counterpart relation/c.p.r./StalnakerVsLewis: if you allow almost arbitrary relations as counterpart relations anyway, you could not use qualitative relations. (Stalnaker 1987a)(2): then you can reconcile counterpart with Haecceitism: if you come across the fact that Lewis (x)(y)(x = y > N(x = y) is wrong, (Lewis pro contingent identity, see above) you can also determine that a thing always has only one counter part per world. Stalnaker/Schwarz: this is not possible with qualitative counterpart relations, since it is always conceivable that several things - for example in a completely symmetrical world - are exactly the same as a third thing in another possible world. LewisVsStalnaker: VsNon qualitative counter part relation: all truths including modal truths should be based on what things exist (in the real world and possible worlds) and what (qualitative) properties they have (>"mosaic": >Humean World). Schwarz I 62 Mathematics/Truthmaking/Fact/Lewis/Schwarz: as with possible worlds, there is no real information: for example, that 34 is the root of 1156, tells us nothing about the world. ((s) That it applies in every possible world. Rules are not truthmakers). Schwarz: For example, that there is no one who shaves those who do not shave themselves is analogously no information about the world. ((s) So not that the world is qualitatively structured). Schwarz: maybe we'll learn more about sentences here. But it is a contingent truth (!) that sentences like "there is someone who shaves those who do not shave themselves" are inconsistent. Solution/Schwarz: the sentence could have meant something else and thus be consistent. Schwarz I 63 Seemingly analytical truth/Lewis/Schwarz: e.g. what do we learn when we learn that ophthalmologists are eye specialists? We already knew that ophthalmologists are ophthalmologists. We have experienced a contingent semantic fact. Modal logic/Modality/Modal knowledge/Stalnaker/Schwarz: Thesis: Modal knowledge could always be understood as semantic knowledge. For example, when we ask if cats are necessary animals, we ask how the terms "cat" and "animal" are to be used. (Stalnaker 1991(3),1996(4), Lewis 1986e(5):36). Knowledge/SchwarzVsStalnaker: that's not enough: to acquire contingent information, you always have to examine the world. (Contingent/Schwarz: empirical, non-semantic knowledge). Modal Truth/Schwarz: the joke about logical, mathematical and modal truths is that they can be known without contact with the world. Here we do not acquire any information. ((s) >making true: no empirical fact "in the world" makes that 2+2 = 4; Cf. >Nonfactualism; >Truthmakers). Schwarz I 207 "Secondary truth conditions"/truth conditions/tr.cond./semantic value/Lewis/Schwarz: contributing to the confusion is that the simple (see above, context-dependent, ((s) "indexical") and variable functions of worlds on truth values are often not only called "semantic values" but also as truth conditions. Important: these truth conditions (tr.cond.) must be distinguished from the normal truth conditions. Lewis: use truth conditions like this. 1986e(5),42 48: for primary, 1969(6), Chapter V: for secondary). Def Primary truth conditions/Schwarz: the conditions under which the sentence should be pronounced according to the conventions of the respective language community. Truth Conditions/Lewis/Schwarz: are the link between language use and formal semantics, their purpose is the purpose of grammar. Note: Def Diagonalization/Stalnaker/Lewis/Schwarz: the primary truth conditions are obtained by diagonalization, i.e. by using world parameters for the world of the respective situation (correspondingly as time parameter the point of time of the situation etc.). Def "diagonal proposition"/Terminology/Lewis: (according to Stalnaker, 1978(7)): primary truth conditions Def horizontal proposition/Lewis: secondary truth condition (1980a(8),38, 1994b(9),296f). Newer terminology: Def A-Intension/Primary Intension/1-Intension/Terminology/Schwarz: for primary truth conditions Def C-Intension/Secondary Intension/2-Intension/Terminology/Schwarz: for secondary truth conditions Def A-Proposition/1-Proposition/C-Proposition/2-Propsition/Terminology/Schwarz: correspondingly. (Jackson 1998a(10),2004(11), Lewis 2002b(12),Chalmers 1996b(13), 56,65) Def meaning1/Terminology/Lewis/Schwarz: (1975(14),173): secondary truth conditions. Def meaning2/Lewis/Schwarz: complex function of situations and worlds on truth values, "two-dimensional intention". Schwarz: Problem: this means very different things: Primary truth conditions/LewisVsStalnaker: in Lewis not determined by meta-linguistic diagonalization like Stalnaker's diagonal proposition. Not even about a priori implication as with Chalmer's primary propositions. Schwarz I 227 A posteriori necessity/Metaphysics/Lewis/Schwarz: normal cases are not cases of strong necessity. One can find out for example that Blair is premier or e.g. evening star = morning star. LewisVsInwagen/LewisVsStalnaker: there are no other cases (which cannot be empirically determined). LewisVs Strong Need: has no place in its modal logic. LewisVs telescope theory: possible worlds are not like distant planets where you can find out which ones exist. 1. Robert C.

| Steady State Theory | Verschiedene Vs Steady State Theory | Kanitscheider I 359 Steady State Theory/SST/Bondi/Kanitscheider: Thesis: Priority of cosmology over local physics. Bondi's Thesis: the unclear complexity of the phenomenon world is only one property of the mesocosm. I 360 VsSST: incompatible with our empiricism: a static universe has long been in thermodynamic equilibrium. All development would already have reached its final state. It would no longer be possible to determine the direction of the time flow. Of the two types of motion allowed by Perfect Cosmological Principle, expansion and contraction, contraction is already eliminated because the necessary excess of radiation in relation to matter is lacking. For expansion, however, the steady state theory now needs the assumption of constant additional generation of matter. But this overrides the important principle of hydrodynamic continuity! I 361 However, at the current values for density and recession constant (distance movement of galaxies from each other), the origin of matter would only be one H atom per litre every 5x10 exp 11 years. Conservation of Matter/BondiVsVs: he even believes he can save the conservation of matter. He says that in a certain, observable area, seen globally, the observable amount of matter does not change, i.e. that in a constant eigenvolume matter is preserved, in contrast to the relativistic models, where the conservation applies rather to the coordinate volume. The Def Eigenvolume is the part of space that is fixed by a fixed distance from the observer, while the Def coordinate volume is given by the constancy of the com mobile coordinates. I 362 Steady State Theory/SST: here there is always the same amount of matter within the range of a certain telescope, while here the relativity theory assumes a dilution, i.e. the matter remains the same in the expanding volume. At the SST, the new formation ensures that the total amount of all observable matter remains the same. Observer/SST: when investigating motion, each observer can perceive a preferred direction of motion apart from local deviations, whereby he determines the constant relationship between velocity and distance completely symmetrically within a small Range. In relativistic cosmology this was the starting point for the Weyl principle. Def Weyl-Principle: Postulate: the particles of a substrate (galaxies) lie in spacetime on a bundle of geodesists that start from a point in the past (Big Bang) and never intersect except at this point. From this follows the existence of a family of hyperplanes (t = const) orthogonal to these geodesists and the only parameters possessing cosmic time. I 362/363 Bondi/SST/Steady State Theory: doubts now that in view of the scattering of the fog movement these hyperplanes exist secured. Because of its stationary character, SST does not need Weyl's postulate and can define homogeneity without cosmic time. Thermodynamic imbalance/universe/SST: Explanation: a photon emanating from a star has a very long free path and reaches areas with strongly changed local motion. This shifts its frequency to red. However, the thermal energy it gives off on its way to the surrounding matter is only a very small part of that lost by its original star. Thus the universe represents a kind of cosmic sink for radiant energy. According to the Perfect Cosmological Principle, sources must exist that make up for the loss. Perfect Cosmological Principle: is logically compatible with three types of universes: 1. Static, without new creation of matter, 2. Expanding, with new development I 364 3. Collapsing, with destruction of matter SST/Bondi: believes in the strict relationship between distance and speed R'(t)/R(t) = 1/T. This results in R as an exponential function and the metric of the SST takes the form of the line element of de Sitter. (see above). Already the self-similarity of the scale function shows the basic metric properties of this model. It is not possible for us to recognize at which point of the curve R = et/T we are. The universe has no beginning and no end. I 365 Age/Universe/SST: Advantage over relativistic theories where the inverse Hubble constant led to a too low age. Metric/SST: while the de Sitter metric is unusable in Einstein's representation because it can only be reconciled with vanishing matter, this problem does not occur in the SST: here there is no necessary connection between physical geometry and matter content of space! According to the de Sitter structure, the world has an event horizon, i.e. every clock on a distant galaxy follows in such a way that there is a point in its history after which the emitted light can no longer reach a distant observer. If, however, a particle has formed within the Range that can in principle be reached with ideal instruments, then it can never disappear from its field of view. I 367 Perfect Cosmological Principle: Problem: lies in the statistical character, which applies strictly on a cosmic scale, but not locally, whereby the local environment only ends beyond the galaxy clusters. Steady State Theory/SST/Hoyle: starts from the classical field equations, but changes them so strongly that all Bondi and Gold results that they have drawn from the Perfect Cosmological Principle remain valid. Hoyle/SST: Thesis: In nature a class of preferred directions can obviously be observed in the large-scale movements, which makes a covariant treatment impossible! Only a preferred class of observers sees the universe in the same way. I 368 Weyl Principle/Postulate: defines a unique relationship of each event P to the origin O. It cannot be a strict law of nature, since it is constantly violated in the local area by its own movements! Hoyle: (formula, tensors, + I 368). Through multiple differentiation symmetric tensor field, energy conservation does not apply, matter must constantly arise anew. Matter emergence/SST/Hoyle: there is an interpretation of matter origin caused by negative pressure in the universe. It should then be interpreted as work that this pressure does during expansion! VsSST: the synchronisation of expansion and origin is just as incomprehensible from theory as the fact that it is always matter and not antimatter that arises. (...+ formula, other choice of the coupling constant I 371/72). I 373 Negative Energy: it has been shown to cause the formation rate of particle pairs to "run away": infinite number in finite region. VsSST/Empiricism: many data spoke against the SST: excess of distant and thus early radio sources, redshift of the quasars indicating a slowdown of expansion, background radiation. |
