| 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). |

| Derrida, J. | Habermas Vs Derrida, J. | Derrida I 95 Derrida: no distinction between everyday language and specialist languages. (DerridaVsSearle). I 196 HabermasVsDerrida: there are differences. Derrida over-generalizes poetic language. There has to be a language in which research results can be discussed and progress registered. HabermasVsDerrida: he does not wriggle out of the restrictions of the subject-philosophical paradigm. His attempt to outbid Heidegger does not escape the aporetic structure of the truth events stripped of truth validity. I 211 Subject-Philosophy/Derrida: Habermas: he does not break with her at all. He falls back on it easily in the style of the original philosophy: it would require other names than those of the sign and the re-presentation to be able think about this age: the infinite derivation of the signs who wander about and change scenes. HabermasVsDerrida: not the history of being the first and last, but an optical illusion: the labyrinthine mirror effects of ancient texts without any hope of deciphering the original script. I 213 HabermasVsDerrida: his deconstructions faithfully follow Heidegger. Involuntarily, he exposes the reverse fundamentalism of this way of thinking: the ontological difference and the being are once again outdone by the difference and put down one floor below. I 214 Derrida inherits the weaknesses of the criticism of metaphysics. Extremely general summonings of an indefinite authority. I 233 DerridaVsSearle: no distinction between ordinary and parasitic use - Searle, HabermasVsDerrida: there is a distinction: communication requires common understanding I 240 Derrida’s thesis: in everyday language there are also poetic functions and structures, therefore no difference from literary texts, therefore equal analysability. HabermasVsDerrida: he is insensitive to the tension-filled polarity between the poetic-world-opening and the prosaic-innerworldly language function. I 241 HabermasVsDerrida: for him, the language-mediated processes in the world are embedded in an all prejudicing, world-forming context. Derrida is blind to the fact that everyday communicative practice enables learning processes in the world thanks to the idealizations built into communicative action, against which the world-disclosing power of interpretive language has to prove itself. Experience and judgment are formed only in the light of criticizable validity claims! Derrida neglects the negation potential of communication-oriented action. He lets the problem-solving capacity disappear behind the world-generating capacity of language. (Similarly Rorty) I 243 HabermasVsDerrida: through the over-generalization of the poetic language function he has no view of the complex relationships of a normal linguistic everyday practice anymore. Rorty II 27 HabermasVsDerrida, HabermasVsHeidegger/Rorty: "subject philosophy": misguided metaphysical attempt to combine the public and the private. Error: thinking that reflection and introspection could achieve what can be actually only be effected by expanding the discussion frame and the participants. II 30 Speaking/Writing/RortyVsDerrida: his complex argument ultimately amounts to a strengthening of the written word at the expense of the spoken. II 32 Language/Communication/HabermasVsDerrida: Derrida denies both the existence of a "peculiarly structured domain of everyday communicative practice" and an "autonomous domain of fiction". Since he denies both, he can analyze any discourse on the model of poetic language. Thus, he does not need to determine language. II 33 RortyVsHabermas: Derrida is neither obliged nor willing to let "language in general" be "determined" by anything. Derrida could agree fully with Habermas in that "the world-disclosing power of interpretive language must prove itself" before metaphors are literarily absorbed and become socially useful tools. RortyVsHabermas: he seems to presuppose that X must be demonstrated as a special case of Y first in order to treat X as Y. As if you could not simply treat X as Y, to see what happens! Deconstruction/Rorty: language is something that can be effective, out of control or stab itself in the back, etc., under its own power. II 35 RortyVsDeconstruktion: nothing suggests that language can do all of this other than an attempt to make Derrida a huge man with a huge topic. The result of such reading is not the grasping of contents, but the placement of texts in contexts, the interweaving of parts of various books. The result is a blurring of genre boundaries. That does not mean that genera "are not real". The interweaving of threads is something else than the assumption that philosophy has "proven" that colors really "are indeterminate and ambiguous." Habermas/Rorty: asks why Heidegger and Derrida still nor advocate those "strong" concepts of theory, truth and system, which have been a thing of the past for more than 150 years. II 36 Justice/Rawls Thesis: the "just thing" has priority over the "good thing". Rawls/Rorty: democratic societies do not have to deal with the question of "human nature" or "subject". Such issues are privatized here. Foundation/Rorty Thesis: there is no Archimedean point from which you can criticize everything else. No resting point outside. RortyVsHabermas: needs an Archimedean point to criticize Foucault for his "relativism". Habermas: "the validity of transcendental spaces and times claimed for propositions and norms "erases space and time"." HabermasVsDerrida: excludes interaction. |

| Kripke, S. A. | Stalnaker Vs Kripke, S. A. | Stalnaker I 125 VsContingent Identity/Stalnaker: if it is possible that one thing would be two things, then there is an a that this thing in the possible world (poss.w.) is w1 and b and c in w2. Then the cross world identities b = a and a = c should both be true but the innerworldly identity b = c is wrong! (In w2). That precisely violates the transitivity of identity. Solution/Stalnaker: we have to ask in which poss.w. this statement is made. In w1 b = c is also true that means it is true in w1 that the individual that is b in w2 is identical to the one that is c in w2. That is no violation of the transitivity. Versus: From the perspective of w2: here b = c is wrong (see above). What about b = a and c = a? Those identify two individuals that are identical in w1 with an individual from w1. Problem: from the perspective of w2 the description "the individual that is identical to a in w1" is an unsuitable description. Hence: w2: from the perspective of w2 identity statements are either false, without truth value or ambiguous. Analogous to E.g. Russell is the author of Principia Mathematica – the author of PM is Whitehead - so Russell is Whitehead. (see above the counterpart relation has to be flexible, it may not require transitivity). I 184 Metaphysics/Kripke/Stalnaker: not all his metaphysical assertions are equally convincing. On the one hand a) is hard to deny that we can accept Potentialities and opportunities for certain individuals reasonably, regardless of the manner in which the individual is specified on the other hand: b) is less convincing that Kripke denies some possibilities that individuals could have. StalnakerVsKripke: it is not convincing that Kripke does not allow on the one hand, that Shakespeare could have had other parents, on the other hand could have lived in another century. How should that be possible? KripkeVsVs/Stalnaker: would say that we are if we accept such things at all, we are confused. This counterfactual possibilities are not coherent. Possible worlds/poss.w./Stalnaker: are not made to clarify metaphysical questions. Metaphysics/Kripke/Stalnaker: Kripke's metaphysical theses do not require his theories on reference and intentionality. Is it reversed that his causal theory requires his metaphysical image? Stalnaker: the metaphysical thesis about the identification of individuals on poss.w. is easy to separate from the theory that names are rigid designators whose reference can be found on causal interaction. I 181 Object/properties/thing/object/SearleVsWittgenstein/SearleVsTractatus/Stalnaker: (Searle was not directed at the time against Kripke, whose book was published later). Kripke/Stalnaker: but he also makes the metaphysical distinction between object and properties what Searle rejects. |

| Mundy, B. | Field Vs Mundy, B. | I 199 Representation Theorem/VsRelationism: Relationism cannot take over the representation theorems from substantivalism either, because these depend on structural regularities (regularity of spacetime structure). And this regularity of spacetime is lost in relationalism. ((s) because there should be no empty sp.t., the sp.t. itself is bound to (empirically irregularly) occurring matter). Wrong Solution/Mundy: (1983): has proven a "representation theorem" which is not based on structural regularities. But that does not help heavy duty Platonism, because it generates numerical functors only from other numerical functors. That means he does not take predicates which put matter particles (point particles) in relation to each other, but a functor k: that refers particles to real numbers. E.g. For every three-point particle a real number that represents the inner product of two vectors which have one of these points as a common starting point, and the other two as endpoints. From this he extracts (several) coordinate systems, so that we have a representation theorem of species. FieldVsMundy: this does not serve the purposes for which representation theorems were originally developed, because it does not depart from a non-numeric base. Mundy: also sees that the R should not use any functions of point particles to real numbers as the basis for its formulation of physics. Therefore, he reformulates the equation: old: k(p,q,r) = a (where a is a real number) new: ka(p,q,r) so that we have an uncountable, infinite set of 3-digit space relations, one for every real number. (Mundy, 1983, p 212, 223.) FieldVsMundy: this does not solve any problem, because it’s only a notational trick. ((s) notation, orthography, paraphrasing, renaming >Rorty: "redescription" not a mere renaming, because description (language) necessitates stronger revision than replacing individual predicates with others. Potentially different number of digits). FieldVsMundy: if you really wanted to interpreted the ka’s as 3-digit spatial relations, the a’s would have to be considered as unquantifiable indices. Then we would have uncountably many primitive predicates, and thus no theory would be possible. Index/Quantification/(s): it is impossible to quantify on indices. Indices are not quantifiable. Mundy: of course, does not treat the indices as unquantifiable, but he re-writes them: k(p,q,r) = a if he wants to quantify on a. FieldVsMundy: but a quantifiable index is simply a variable that appears in a different place. And with the re-naming we do not change the fact that we have a 4-digit relation of which one term is a real number. Conclusion: With that you cannot take advantage of the difference between moderate Platonism and heavy duty Platonism. |
