Chalmers, D. | Stalnaker Vs Chalmers, D. | I 194 Semantic Facts/Semantics/Stalnaker: the semantics assumes that the Semantic facts about a language that specifies two types of intensions that can be abstracted from these very Semantic facts and then also cannot be applied in possible worlds (poss.w.) in which those facts do not persist. We can take the primary intension in the actual world and consider its extension in any poss.w.. Meta semantics/Stalnaker: only assumes that the semantics (plus context) I 195 defines a normal intension. So it assumes less what can be derived from a semantics for a language. primary intension/meta semantics/Stalnaker: here these functions have a more limited domain. Their values are only determinded for such poss.w. that contain this expression (the token). Semantics/meta semantics/Chalmers: this distinction makes little difference. StalnakerVsChalmers: on the contrary: it is not only about how you distinguish the different representations how referents are dependent from facts, the distinction reflects two different ways to use the two-dimensional device. Difference: a) we characterize the relevant two-dimensional and primary intensions as types of meaning, b) not as meaning. Stalnaker: this has consequences for our understanding of a priori knowledge and truth. I 202 Necessary a posteriori: is divided into necessary truth a priori knowable by conceptual analysis and a part which is only a posteriori knowable but this one is contingent. Chalmers and Jackson show this with two-dimensional semantics. Stalnaker: I agree with the two that this phenomenon has its roots in the relation between how we represent the world and the world itself, but Two-dimensional semantics/StalnakerVsJackson/StalnakerVsChalmers: thesis: I think that shows something about the nature of mental representations and not only on the contingent functioning of languages. I 210 Two-dimensional frame/Stalnaker: can be interpreted a) as Kaplan originally but extended b) meta-semantically. I 211 Ad a) then the causal chains are part of the semantic content Chalmers: this makes little difference StalnakerVsChalmers: the difference is greater than he thinks. necessity a posteriori is then analyzed differently. Causal chain/Stalnaker: if it is part of the descriptive semantics then it is said by it how - given this descriptive semantics - the references are determined by the facts. Problem: how did the facts determine which semantics the language has? |

Hume, D. | Kripke Vs Hume, D. | Apriori: Some philosophers modify the modalities in this characterization somehow from "may" to "shall". They think that if something belongs to the realm of a priori knowledge it is impossible to recognize it empirically.(Hume). This is wrong! (KripkeVsHume). E.g. The computer can give an answer to the question of whether particular numbers are primes. Nobody has calculated or proved this, but the computer gave the answer. I 45 a posteriori: A mathematical truth can be known a posteriori by looking at a computer or by asking a mathematician (e.g. naturally a posteriori). The philosophical analysis tells us that it could not be contingent and therefore all empirical knowledge of its truth is automatically an empirical knowledge of its necessity.(KripkeVsHume, KripkeVsKant) I 181 |

Jackson, F. | Schwarz Vs Jackson, F. | Schwarz I 226 A posteriori necessity/SchwarzVsLewis/SchwarzVsJackson: but from that does not follow that if the physical truths imply anything necessary - if they constitute a metaphysical basis for all truths about the situation on the actual situation that this implication then must be also a priori. It could be that the metaphysical basis only implies a posteriori: E.g. the phrase "everything is as it actually is". Implies necessary all truths, it is only in the actual world (actual world) true. A priori it implies nothing! ((s) it is not true for any possible world, but in every possible world itself). > Panpsychism: Panpsychism/Panprotopsychism/Chalmers/Schwarz: (Chalmers 2002) takes this gap as an advantage: The starting point is a kind. Def Quidditism (see above 5.4): Thesis: our physical theory describe how physical things and properties relate to each other, what they are, but they leave their intrinsic nature in the dark. Def Pan(proto)psychism: Thesis: this intrinsic nature of things and properties is mental. E.g. what we know from the outside as a charge -1, turns out to be from the inside as pain. ((s)> Two Aspects teaching). Now, if our physical vocabulary is rigid (that means that it always applies in the field of modal operators on what plays for us the causal structural role (that means to pain), then the physical truths imply necessary the mental, but the implication does not need to be a priori. Problem: the physical truths are not sufficient to tell us exactly in what situation we are in, particularly with regard to the intrinsic nature of physical quantities. |

Kant | Kripke Vs Kant | I 135Kant: "All analytic judgments are based entirely on the principle of contradiction and by their nature are a priori knowledge, the definitions on which they are based on may be empirical or not. Since the predicate has been thought of in terms of the subject, it cannot be negated by the first." I 181 That is precisely why all analytic propositions are a priori judgments even though their terms are empirical. E.g. gold is a yellow metal. In order to know this, I need no further experience beyond my definition of gold. If that makes up my definition, I am only able to segment my definition, I cannot look anywhere else for it. Kripke: Kant seems to say that gold means simply yellow metal. KripkeVsKant: Is Kant right? According to scientists, it is very difficult to define what a metal is. We also need to know the periodic table. One might think that there are actually two definitions, a phenomenological and a scientific one, where the latter replaces the former. Phenomenological: Stretchable, deformable, scientific: Periodic table. (KripkeVs). a posteriori: one can learn a mathematical truth a posteriori by looking at a computer or by asking a mathematician. (e.g. naturally a posteriori). The philosophical analysis tells us that it could not be contingent, and therefore any empirical knowledge of its truth is automatically an empirical knowledge of its necessity.(KripkeVsHume, KripkeVsKant) |

Kripke, S. A. | Lewis Vs Kripke, S. A. | V 251/252 Event/Description/describe/naming/Lewis: is usually specified by accidental properties. Even though it's clear what it meant to specify by its nature. An event applies, for example, to a description, but could also have occurred without applying to the description. Def Event/Lewis: is a class consisting of a region of this world together with different regions of other possible worlds in which the event could have occurred. (because events are always contingent). What corresponds to the description in one region does not correspond to it in another region (another possible world). You can never reach a complete inventory of the possible descriptions of an event. 1. artificial description: e.g. "the event that exists in the Big Bang when Essendon wins the final, but the birth of Calvin Coolidge, if not". "p > q, otherwise r". 2. partly by cause or effect 3. by reference to the place in a system of conventions such as signing the check 4. mixing of essential and accidental elements: singing while Rome burns. Example triple property, time, individual, (see above). 5. specification by a point of time, although the event could have occurred sooner or later 6. although individuals can be significantly involved, accidentially associated individuals can be highlighted. 7. it may be that a rich being of an event consists of strolling, but a less fragile (description-dependent) event could only be an accidental strolling. (s) And it may remain unclear whether the event is now essentially characterized by strolls. 8. an event that involves one individual in a significant way may at the same time accidentally involve another: For example, a particular soldier who happens to belong to a particular army, the corresponding event cannot occur in regions where there is no counterpart to this soldier, but if there is a counterpart of the soldier, this belongs to another army. V 253 Then the army gets involved on an accidental basis through its soldier's way. 9. heat: non-rigid designator: (LewisVsKripke): Non-rigid: whatever this role has: whatever this or that manifestation brings forth. Example: heat could also have been something other than molecular movement. Lewis: in a possible world, where heat flow produces the corresponding manifestations, hot things are those that have a lot of heat flow. Schwarz I 55 Being/Context Dependency/LewisVsKripke/SchwarzVsKripke: in certain contexts we can certainly ask e.g. what it would be like if we had had other parents or belonged to another kind. Example statue/clay: assuming, statue and clay both exist exactly for the same time. Should we say that, despite their material nature, they always manage to be in the same place at the same time? Shall we say that both weigh the same, but together they don't double it? Problem: if you say that the two are identical, you get in trouble with the modal properties: For example, the piece of clay could have been shaped completely differently, but not the statue - vice versa: Schwarz I 56 For example, the statue could have been made of gold, but the clay could not have been made of gold. Counterpart theory/Identity: Solution: the relevant similarity relation depends on how we refer to the thing, as a statue or as clay. Counterpart relation: Can (other than identity) not only be vague and variable, but also asymmetric and intransitive. (1968(1),28f): this is the solution for Def Chisholm's Paradox/Schwarz: (Chisholm, 1967(2)): Suppose Kripke could not possibly be scrambled eggs. But surely it could be a little more scrambly if it were a little smaller and yellower! And if he were a little more like that, he could be more like that. And it would be strange if he couldn't be at least a little bit smaller and yellower in that possible world. Counterpart Theory/Solution: because the counterpart relation is intransitive, it does not follow at all that at the end Kripke is scrambled egg. A counterpart of a counterpart from Kripke does not have to be a counterpart of Kripke. (1986e(3),246) I 57 KripkeVsCounterpart Theory/KripkeVsLewis: For example, if we say "Humphrey could have won the election", according to Lewis we are not talking about Humphrey, but about someone else. And nothing could be more indifferent to him ("he couldn't care less"). (Kripke 1980(4): 44f). Counterpart/SchwarzVsKripke/SchwarzVsPlantinga: the two objections misunderstand Lewis: Lewis does not claim that Humphrey could not have won the election, on the contrary: "he could have won the election" stands for the very property that someone has if one of his counterparts wins the election. That's a trait Humphrey has, by virtue of his character. (1983d(5),42). The real problem: how does Humphrey do it that he wins the election in this or that possible world? Plantinga: Humphrey would have won if the corresponding possible world (the facts) had the quality of existence. Lewis/Schwarz: this question has nothing to do with Kripke and Plantinga's intuitions. Schwarz I 223 Name/Description/Reference/Kripke/Putnam/Schwarz: (Kripke 1980(4), Putnam 1975(6)): Thesis: for names and expressions for kinds there is no generally known description that determines what the expression refers to. Thesis: descriptions are completely irrelevant for the reference. Description theory/LewisVsKripke/LewisVsPutnam/Schwarz: this only disproves the naive description theory, according to which biographical acts are listed, which are to be given to the speaker necessarily. Solution/Lewis: his description theory of names allows that e.g. "Gödel" has only one central component: namely that Gödel is at the beginning of the causal chain. Thus, theory no longer contradicts the causal theory of the reference. (1984b(7),59,1994b(8),313,1997(9)c,353f,Fn22). ((s)Vs: but not the description "stands at the beginning of the causal chain", because that does not distinguish one name from any other. On the other hand: "at the beginning of the Gödel causal chain" would be meaningless. Reference/LewisVsMagic theory of reference: according to which reference is a primitive, irreducible relationship (cf. Kripke 1980(4),88 Fn 38), so that even if we knew all non-semantic facts about ourselves and the world, we still do not know what our words refer to, according to which we would need special reference o meters to bring fundamental semantic facts to light. If the magic theory of reference is wrong, then semantic information is not sufficient in principle to tell us what we are referring to with e.g. "Gödel": "if things are this way and that way, "Gödel" refers to this and that". From this we can then construct a description from which we know a priori that it takes Gödel out. This description will often contain indexical or demonstrative elements, references to the real world. I 224 Reference/Theory/Name/Description/Description Theory/LewisVsPutnam/LewisVsKripke/Schwarz: For example, our banana theory does not say that bananas are sold at all times and in all possible worlds in the supermarket. For example, our Gödel theory does not say that Gödel in all possible worlds means Gödel. ((s) >Descriptivism). (KripkeVsLewis: but: names are rigid designators). LewisVsKripke: when evaluating names in the area of temporal and modal operators, you have to consider what fulfills the description in the utterance situation, not in the possible world or in the time that is currently under discussion. (1970c(12),87,1984b(8),59,1997c(9),356f) I 225 A posteriori Necessity/Kripke/Schwarz: could it not be that truths about pain supervene on physically biological facts and thus necessarily follow from these, but that this relationship is not accessible to us a priori or through conceptual analysis? After all, the reduction of water to H2O is not philosophical, but scientific. Schwarz: if this is true, Lewis makes his work unnecessarily difficult. As a physicist, he would only have to claim that phenomenal terms can be analyzed in non-phenomenal vocabulary. One could also save the analysis of natural laws and causality. He could simply claim these phenomena followed necessarily a posteriori from the distribution of local physical properties. a posteriori necessary/LewisVsKripke: this is incoherent: that a sentence is a posteriori means that one needs information about the current situation to find out if it is true. For example, that Blair is the actual prime minister (in fact an a posteriori necessity) one needs to know that he is prime minister in the current situation, Schwarz I 226 which is in turn a contingent fact. If we have enough information about the whole world, we could in principle a priori conclude that Blair is the real Prime Minister. a posteriori necessities follow a priori from contingent truths about the current situation.

Lewis, D. | Inwagen, Vs Lewis, D. | Schwarz I 227 Metaphysics/being/essential/van InwagenVsLewis/StalnakerVsLewis: knowing contingent facts about the current situation would in principle not be sufficient to know all a posteriori necessities: Def strong necessity/Chalmers: thesis: in addition to substantial contingent truths, there are also substantial modal truths: e.g. that Kripke is essentially a human being, e.g. that pain is essentially identical to XY. Important argument: knowledge of contingent facts is not sufficient to recognize these modal facts.

Quine, W.V.O. | Stalnaker Vs Quine, W.V.O. | I 71 Essentialism/today/VsQuine: most modal logicians today contradict Quine and accept the connection between modal logic (ML) and essentialism and accept the essentialism. Instead of, like Quine back then, saying: "so much the worse for quantified ML" they say, "so much the better for the essentialism". I 72 Essence/essentialism/essential property/LeibnizVsQuine/Stalnaker: contradicted Quine in the first way: thesis: each property of each individual constitutes his nature and only the existence of the thing as a whole is contingent. today: David Lewis with his counterpart theory is a modern successor of Leibniz. Counterpart/Lewis: things of the actual world have counterparts in other possible worlds (poss.w.). Things that resemble them more than any other thing. Therefore, no individual can have accidental properties, properties that they are lacking in another poss.w.. I 201 Quine/Stalnaker: taught us to be skeptical about the idea of necessity, analyticity and knowledge a priori. However, he did not question the empiricist assumptions that these concepts stand and fall with each other. KripkeVsQuine/Stalnaker: only Kripke pulled apart these concepts by finding examples of truths that are necessary although they are only a posteriori knowable and those that still are contingent but still a priori knowable. II 24 Belief/Mentalese/Field/Stalnaker: his thesis was to reinterpret the intentional-psychological relation into a psychological but non-intentional and a semantic but not psychological relationship - between a sentence and the expressed proposition. Belief ascription/Quine/Stalnaker: his goal was to generalize the ascription. By this an obligation to singular propositions should be avoided. StalnakerVsQuine: but the project changes its character when it comes to the general case. De re-ascription/Stalnaker: should better not be regarded as indirect and vague, II 25 but simply as examples that show the essential characteristics of the intentional: Ascription: if we ascribe intentional states, the types, properties and relations to which we refer here, we see the world and with them we characterize the world as someone sees it. Important argument: that is just not an indirect but a direct way to get to the content. II 160 Def singular proposition/Stalnaker: here e.g. a singular proposition ascribes Ortcutt to be a spy. Structured singular proposition/Stalnaker: (for those for whom propositions are structured entities): then singular propositions are those which have an individual as a constituent. (StalnakerVsStructured propositions). Singular proposition/poss.w.-semantics/semantics of possible worlds/Stalnaker: for those for whom the propositions are sets of poss.w., (Stalnaker pro)): then a singular proposition is a proposition whose truth depends on the properties of a particular individual. Singular proposition/Stalnaker: the identity of a singular proposition is a function of an individual instead of a concept or givenness of an individual. StalnakerVsQuine: this semantic approach is simpler and less ad hoc than that of Quine. II 161 De re/ascription/belief de re/singular proposition/sing Prop/StalnakerVsQuine/Stalnaker: the semantic approach understands the ascription of a belief de re then as ascription of a particular faith (unlike Quine). What it means to believe a singular proposition? How is it to believe that Ortcutt himself is a spy? And not only that the person fulfills the description or a belief subject that is given in a certain way? Problem: suppose Ralph knows Ortcutt in two different ways (beach, brown hat). Which singular proposition about Ortcutt does he believe? bad solution: many authors think that there would have to be a special relation of acquaintance here. Acquaintance/Stalnaker: problem: to provide a semantic relation for them. 1. the first strategy makes belief de re then too easy: e.g. Poirot believes that it was the butler simply due to the two facts that 1. the butler was it and 2. Poirot believes that it was the person who was it. 2. the second strategy makes belief de re too difficult: then Ralph, who knows Ortcutt, has two contradictory convictions. Solution: a) to strengthen the relation of acquaintance so that misidentifications are impossible. Vs: such mistakes are almost always possible! Then you could have only de re-convictions about yourself. b) the "divide-and-conquer" argument: we tell the story of Ralph in two parts. 1. Ralph sees Ortcutt with a brown hat 2. Ralph sees Ortcutt at the beach. II 162 Then it is quite natural that in Ralph believes in one story that Ortcutt is a spy, and not in the other story. There is no reason to assume that Ralph would have had to change his mind in between. II 163 De re/ascription/belief de re/StalnakerVsQuine/StalnakerVsKaplan/Stalnaker: thesis: we assume instead propositions as sets of poss.w.. Pragmatic Analysis/pragmatics/Stalnaker: has in common with the semantic that certain convictions are ascribed but - unlike the semantic - it does not assume a particular type of propositions and also does not require an increased acquaintance relationship. That means the individuals of which something is believed are not constituents of the proposition. Proposition: its purpose is to pick out a subset of the relevant context set. Ascription/de re/Stalnaker: (all authors): the way how the ascribing formulates its ascription is independent of the way the believer would formulate his conviction or the way how he thinks about the individual Pragmatic approach/Stalnaker: (…+…) |

Reductionism | Physicalism Vs Reductionism | Schwarz I 156 Physicalism/Vs Reductionism/VsLewis. other authors: Physicalism is not at all fixed on the a priori derivability of mental from physical truths, only on supervenience of mental on physical facts. But this does not have to be a priori. It can be a posteriori necessity. For example, the relationship between H2O-truths and water truths. (This is non-reductive physicalism). LewisVs: this is a misunderstanding about a posteriori necessity: e.g. Assuming that "water is H2O" is necessary a posteriori: this is not because there is a modal fact, a necessity that we can only discover a posteriori, but rather because the meaning of certain words depends on contingent, empirical factors: according to our conventions, in all possible worlds "water" picks out the substance that fills our lakes and streams. "Water is H2O" is a posteriori, because you first have to find out that the material that fills streams and lakes in our country is H2O. This is a contingent fact that usually requires chemical analysis, no excursions into modal space. The H2O-truths therefore a priori imply the water truths. If pain a posteriori is identical with a physical state, then this must also be due to the fact that the reference to "pain" depends on contingent facts, on what kind of state plays the and the role with us ((s) not what kind of linguistic convention we have). (see 1994b(1),296f). 1. David Lewis [1994b]: “Reduction of Mind”. In Samuel Guttenplan (ed.), A Companion to the Philosophy of Mind, Oxford: Blackwell, 412–431, und in [Lewis 1999a] |

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.

Kripke/Alan Sidelle/Jackson/Chalmers/Stalnaker: (Sidelle 1989, Jackson 1998, Chalmers 1996) Thesis: Kripke's theses can be reconciled with them, I 202 that all necessity has its root in language and our ideas. However, in a more complex way than empiricism assumed. Then there is no irreducible necessity a posteriori. Necessary a posteriori: is then divisible into necessary truth that is a priori knowable by conceptual analysis, and a part that is only a posteriori knowable, but this is contingent. Chalmers and Jackson show this with two-dimensional semantics. |

Two Dimensional Sem. | Stalnaker, R. | I 201/202 Two-Dimensional Semantics/StalnakerVsJackson/StalnakerVsChalmers: Thesis: I think this shows something about the nature of mental representation and not just about the contingent functioning of languages. I 204 Two-dimensional Frame/Stalnaker: I will show the two ways to interpret it. a) semantic, b) metasemantic. Thesis: with this distinction I would like to reduce necessity a posteriori as Jackson and Chalmers have done. Thus the problem of intentionality can be solved. |
