12667 | Metaphysics aims at the simplest explanation, without regard to testability [Ellis] |
13567 | Ontology should give insight into or an explanation of the world revealed by science [Ellis] |
5486 | Essentialism says metaphysics can't be done by analysing unreliable language [Ellis] |
8349 | The best way to do ontology is to make sense of our normal talk [Davidson] |
8868 | Objective truth arises from interpersonal communication [Davidson] |
3969 | There are no ultimate standards of rationality, since we only assess others by our own standard [Davidson] |
3972 | Truth and objectivity depend on a community of speakers to interpret what they mean [Davidson] |
6396 | A sentence is held true because of a combination of meaning and belief [Davidson] |
23295 | Truth cannot be reduced to anything simpler [Davidson] |
19160 | A comprehensive theory of truth probably includes a theory of predication [Davidson] |
23284 | Plato's Forms confused truth with the most eminent truths, so only Truth itself is completely true [Davidson] |
23286 | Truth can't be a goal, because we can neither recognise it nor confim it [Davidson] |
19151 | Antirealism about truth prevents its use as an intersubjective standard [Davidson] |
23291 | Without truth, both language and thought are impossible [Davidson] |
8188 | Davidson takes truth to attach to individual sentences [Davidson, by Dummett] |
19144 | 'Epistemic' truth depends what rational creatures can verify [Davidson] |
19044 | Saying truths fit experience adds nothing to truth; nothing makes sentences true [Davidson] |
18702 | Names, descriptions and predicates refer to things; without that, language and thought are baffling [Davidson] |
23292 | Correspondence can't be defined, but it shows how truth depends on the world [Davidson] |
18902 | Correspondence theories can't tell you what truths correspond to [Davidson] |
23298 | Neither Aristotle nor Tarski introduce the facts needed for a correspondence theory [Davidson] |
19148 | There is nothing interesting or instructive for truths to correspond to [Davidson] |
19166 | The Slingshot assumes substitutions give logical equivalence, and thus identical correspondence [Davidson] |
19167 | Two sentences can be rephrased by equivalent substitutions to correspond to the same thing [Davidson] |
19081 | Coherence with a set of propositions suggests we can know the proposition corresponds [Davidson, by Donnellan] |
19150 | Coherence truth says a consistent set of sentences is true - which ties truth to belief [Davidson] |
19145 | We can explain truth in terms of satisfaction - but also explain satisfaction in terms of truth [Davidson] |
19146 | Satisfaction is a sort of reference, so maybe we can define truth in terms of reference? [Davidson] |
19174 | Axioms spell out sentence satisfaction. With no free variables, all sequences satisfy the truths [Davidson] |
23288 | When Tarski defines truth for different languages, how do we know it is a single concept? [Davidson] |
23297 | The language to define truth needs a finite vocabulary, to make the definition finite [Davidson] |
19136 | Many say that Tarski's definitions fail to connect truth to meaning [Davidson] |
19139 | Tarski does not tell us what his various truth predicates have in common [Davidson] |
19147 | Truth is the basic concept, because Convention-T is agreed to fix the truths of a language [Davidson] |
19172 | To define a class of true sentences is to stipulate a possible language [Davidson] |
23296 | We can elucidate indefinable truth, but showing its relation to other concepts [Davidson] |
19153 | Truth is basic and clear, so don't try to replace it with something simpler [Davidson] |
23287 | Disquotation only accounts for truth if the metalanguage contains the object language [Davidson] |
19170 | Tarski is not a disquotationalist, because you can assign truth to a sentence you can't quote [Davidson] |
13604 | Real possibility and necessity has the logic of S5, which links equivalence classes of worlds of the same kind [Ellis] |
12666 | We can base logic on acceptability, and abandon the Fregean account by truth-preservation [Ellis] |
7332 | There is a huge range of sentences of which we do not know the logical form [Davidson] |
18914 | Davidson controversially proposed to quantify over events [Davidson, by Engelbretsen] |
19140 | 'Satisfaction' is a generalised form of reference [Davidson] |
13606 | Humean conceptions of reality drive the adoption of extensional logic [Ellis] |
12688 | Mathematics is the formal study of the categorical dimensions of things [Ellis] |
12683 | Objects and substances are a subcategory of the natural kinds of processes [Ellis] |
7771 | We need 'events' to explain adverbs, which are adjectival predicates of events [Davidson, by Lycan] |
8860 | Language-learning is not good enough evidence for the existence of events [Yablo on Davidson] |
7949 | Varied descriptions of an event will explain varied behaviour relating to it [Davidson, by Macdonald,C] |
8348 | If we don't assume that events exist, we cannot make sense of our common talk [Davidson] |
9843 | You can't identify events by causes and effects, as the event needs to be known first [Dummett on Davidson] |
14602 | Events can only be individuated causally [Davidson, by Schaffer,J] |
14004 | We need events for action statements, causal statements, explanation, mind-and-body, and adverbs [Davidson, by Bourne] |
12670 | A physical event is any change of distribution of energy [Ellis] |
8278 | The claim that events are individuated by their causal relations to other events is circular [Lowe on Davidson] |
23285 | If we try to identify facts precisely, they all melt into one (as the Slingshot Argument proves) [Davidson] |
15002 | If the best theory of adverbs refers to events, then our ontology should include events [Davidson, by Sider] |
13584 | The extension of a property is a contingent fact, so cannot be the essence of the property [Ellis] |
5468 | Properties are 'dispositional', or 'categorical' (the latter as 'block' or 'intrinsic' structures) [Ellis, by PG] |
13587 | There is no property of 'fragility', as things are each fragile in a distinctive way [Ellis] |
12673 | Physical properties are those relevant to how a physical system might act [Ellis] |
13577 | Typical 'categorical' properties are spatio-temporal, such as shape [Ellis] |
9436 | The property of 'being an electron' is not of anything, and only electrons could have it [Ellis] |
5469 | The passive view of nature says categorical properties are basic, but others say dispositions [Ellis] |
12665 | I support categorical properties, although most people only want causal powers [Ellis] |
12682 | Essentialism needs categorical properties (spatiotemporal and numerical relations) and dispositions [Ellis] |
12684 | Spatial, temporal and numerical relations have causal roles, without being causal [Ellis] |
13582 | 'Being a methane molecule' is not a property - it is just a predicate [Ellis] |
12672 | Properties and relations are discovered, so they can't be mere sets of individuals [Ellis] |
19173 | Treating predicates as sets drops the predicate for a new predicate 'is a member of', which is no help [Davidson] |
5456 | Redness is not a property as it is not mind-independent [Ellis] |
18398 | Space, time, and some other basics, are not causal powers [Ellis] |
13580 | Causal powers must necessarily act the way they do [Ellis] |
13598 | Causal powers are often directional (e.g. centripetal, centrifugal, circulatory) [Ellis] |
12676 | Causal powers can't rest on things which lack causal power [Ellis] |
13568 | Basic powers may not be explained by structure, if at the bottom level there is no structure [Ellis] |
13586 | Maybe dispositions can be explained by intrinsic properties or structures [Ellis] |
5481 | Properties have powers; they aren't just ways for logicians to classify objects [Ellis] |
23781 | Categoricals exist to influence powers. Such as structures, orientations and magnitudes [Ellis, by Williams,NE] |
13585 | The most fundamental properties of nature (mass, charge, spin ...) all seem to be dispositions [Ellis] |
5458 | Nearly all fundamental properties of physics are dispositional [Ellis] |
13596 | A causal power is a disposition to produce forces [Ellis] |
13599 | Powers are dispositions of the essences of kinds that involve them in causation [Ellis] |
12686 | Causal powers are a proper subset of the dispositional properties [Ellis] |
13572 | There are 'substantive' (objects of some kind), 'dynamic' (events of some kind) and 'property' universals [Ellis] |
13573 | Universals are all types of natural kind [Ellis] |
12685 | Categorical properties depend only on the structures they represent [Ellis] |
5443 | Kripke and others have made essentialism once again respectable [Ellis] |
5444 | 'Individual essences' fix a particular individual, and 'kind essences' fix the kind it belongs to [Ellis] |
13571 | Scientific essentialism doesn't really need Kripkean individual essences [Ellis] |
12679 | A real essence is a kind's distinctive properties [Ellis] |
5462 | Essential properties are usually quantitatively determinate [Ellis] |
5448 | 'Real essence' makes it what it is; 'nominal essence' makes us categorise it a certain way [Ellis] |
13578 | The old idea that identity depends on essence and behaviour is rejected by the empiricists [Ellis] |
5477 | One thing can look like something else, without being the something else [Ellis] |
13576 | Necessities are distinguished by their grounds, not their different modalities [Ellis] |
12668 | Metaphysical necessity holds between things in the world and things they make true [Ellis] |
5479 | Scientific essentialists say science should define the limits of the possible [Ellis] |
19142 | Probability can be constrained by axioms, but that leaves open its truth nature [Davidson] |
12687 | Metaphysical necessities are those depending on the essential nature of things [Ellis] |
5483 | Essentialists deny possible worlds, and say possibilities are what is compatible with the actual world [Ellis] |
13570 | Individual essences necessitate that individual; natural kind essences necessitate kind membership [Ellis] |
5447 | Metaphysical necessities are true in virtue of the essences of things [Ellis] |
5476 | Essentialists say natural laws are in a new category: necessary a posteriori [Ellis] |
5478 | Imagination tests what is possible for all we know, not true possibility [Ellis] |
5482 | Possible worlds realism is only needed to give truth conditions for modals and conditionals [Ellis] |
11145 | Having a belief involves the possibility of being mistaken [Davidson] |
8806 | The concepts of belief and truth are linked, since beliefs are meant to fit reality [Davidson] |
6397 | The concept of belief can only derive from relationship to a speech community [Davidson] |
8867 | A belief requires understanding the distinctions of true-and-false, and appearance-and-reality [Davidson] |
5453 | Essentialists mostly accept the primary/secondary qualities distinction [Ellis] |
5466 | Primary qualities are number, figure, size, texture, motion, configuration, impenetrability and (?) mass [Ellis] |
8252 | Davidson believes experience is non-conceptual, and outside the space of reasons [Davidson, by McDowell] |
6400 | Without the dualism of scheme and content, not much is left of empiricism [Davidson] |
8255 | Davidson says the world influences us causally; I say it influences us rationally [McDowell on Davidson] |
23294 | It is common to doubt truth when discussing it, but totally accept it when discussing knowledge [Davidson] |
8804 | Reasons for beliefs are not the same as evidence [Davidson] |
8802 | Sensations lack the content to be logical; they cause beliefs, but they cannot justify them [Davidson] |
8801 | Coherent justification says only beliefs can be reasons for holding other beliefs [Davidson] |
8805 | Skepticism is false because our utterances agree, because they are caused by the same objects [Davidson] |
10347 | Objectivity is intersubjectivity [Davidson] |
6398 | Different points of view make sense, but they must be plotted on a common background [Davidson] |
12669 | Science aims to explain things, not just describe them [Ellis] |
13607 | If events are unconnected, then induction cannot be solved [Ellis] |
5485 | Emeralds are naturally green, and only an external force could turn them blue [Ellis] |
8347 | Explanations typically relate statements, not events [Davidson] |
13597 | Good explanations unify [Ellis] |
5484 | Essentialists don't infer from some to all, but from essences to necessary behaviour [Ellis] |
13601 | Explanations of particular events are not essentialist, as they don't reveal essential structures [Ellis] |
17472 | Thick mechanisms map whole reactions, and thin mechanism chart the steps [Weisberg/Needham/Hendry] |
17471 | Using mechanisms as explanatory schemes began in chemistry [Weisberg/Needham/Hendry] |
13569 | To give essentialist explanations there have to be natural kinds [Ellis] |
3960 | There are no such things as minds, but people have mental properties [Davidson] |
8866 | If we know other minds through behaviour, but not our own, we should assume they aren't like me [Davidson] |
10346 | Knowing other minds rests on knowing both one's own mind and the external world [Davidson, by Dummett] |
19169 | Predicates are a source of generality in sentences [Davidson] |
13600 | The point of models in theories is not to idealise, but to focus on what is essential [Ellis] |
4042 | Metaphysics requires the idea of people (speakers) located in space and time [Davidson] |
4983 | There are no rules linking thought and behaviour, because endless other thoughts intervene [Davidson] |
3529 | Reduction is impossible because mind is holistic and brain isn't [Davidson, by Maslin] |
3964 | If the mind is an anomaly, this makes reduction of the mental to the physical impossible [Davidson] |
2307 | Anomalous monism says nothing at all about the relationship between mental and physical [Davidson, by Kim] |
5497 | Mind is outside science, because it is humanistic and partly normative [Davidson, by Lycan] |
4081 | Anomalous monism says causes are events, so the mental and physical are identical, without identical properties [Davidson, by Crane] |
2321 | If rule-following and reason are 'anomalies', does that make reductionism impossible? [Davidson, by Kim] |
3404 | Davidson claims that mental must be physical, to make mental causation possible [Davidson, by Kim] |
3963 | There are no strict psychophysical laws connecting mental and physical events [Davidson] |
3965 | Mental entities do not add to the physical furniture of the world [Davidson] |
3961 | Obviously all mental events are causally related to physical events [Davidson] |
3405 | If mental causation is lawless, it is only possible if mental events have physical properties [Davidson, by Kim] |
3966 | The correct conclusion is ontological monism combined with conceptual dualism [Davidson] |
16041 | Supervenience of the mental means physical changes mental, and mental changes physical [Davidson] |
6620 | Davidson sees identity as between events, not states, since they are related in causation [Davidson, by Lowe] |
6383 | Cause unites our picture of the universe; without it, mental and physical will separate [Davidson] |
3429 | Multiple realisability was worse news for physicalism than anomalous monism was [Davidson, by Kim] |
6392 | Thought depends on speech [Davidson] |
3967 | Absence of all rationality would be absence of thought [Davidson] |
6393 | A creature doesn't think unless it interprets another's speech [Davidson] |
6386 | In no important way can psychology be reduced to the physical sciences [Davidson] |
6175 | External identification doesn't mean external location, as with sunburn [Davidson, by Rowlands] |
3974 | Our meanings are partly fixed by events of which we may be ignorant [Davidson] |
8872 | It is widely supposed that externalism cannot be reconciled with first-person authority [Davidson] |
8874 | It is hard to interpret a speaker's actions if we take a broad view of the content [Davidson] |
11144 | Concepts are only possible in a language community [Davidson] |
6387 | A minimum requirement for a theory of meaning is that it include an account of truth [Davidson] |
19149 | If we reject corresponding 'facts', we should also give up the linked idea of 'representations' [Davidson] |
19163 | You only understand an order if you know what it is to obey it [Davidson] |
15160 | Davidson rejected ordinary meaning, and just used truth and reference instead [Davidson, by Soames] |
14612 | Davidson aimed to show that language is structured by first-order logic [Davidson, by Smart] |
4041 | Sentences held true determine the meanings of the words they contain [Davidson] |
6391 | A theory of truth tells us how communication by language is possible [Davidson] |
23289 | Knowing the potential truth conditions of a sentence is necessary and sufficient for understanding [Davidson] |
19152 | Utterances have the truth conditions intended by the speaker [Davidson] |
19162 | Meaning involves use, but a sentence has many uses, while meaning stays fixed [Davidson] |
6395 | An understood sentence can be used for almost anything; it isn't language if it has only one use [Davidson] |
23290 | It could be that the use of a sentence is explained by its truth conditions [Davidson] |
19131 | We recognise sentences at once as linguistic units; we then figure out their parts [Davidson] |
6394 | The pattern of sentences held true gives sentences their meaning [Davidson] |
6388 | Is reference the key place where language and the world meet? [Davidson] |
6390 | With a holistic approach, we can give up reference in empirical theories of language [Davidson] |
6389 | To explain the reference of a name, you must explain its sentence-role, so reference can't be defined nonlinguistically [Davidson] |
19156 | Modern predicates have 'places', and are sentences with singular terms deleted from the places [Davidson] |
5457 | Predicates assert properties, values, denials, relations, conventions, existence and fabrications [Ellis, by PG] |
19176 | The concept of truth can explain predication [Davidson] |
7772 | Compositionality explains how long sentences work, and truth conditions are the main compositional feature [Davidson, by Lycan] |
19133 | If you assign semantics to sentence parts, the sentence fails to compose a whole [Davidson] |
7327 | Davidson thinks Frege lacks an account of how words create sentence-meaning [Davidson, by Miller,A] |
7331 | A theory of meaning comes down to translating sentences into Fregean symbolic logic [Davidson, by Macey] |
19132 | Top-down semantic analysis must begin with truth, as it is obvious, and explains linguistic usage [Davidson] |
7769 | You can state truth-conditions for "I am sick now" by relativising it to a speaker at a time [Davidson, by Lycan] |
19158 | 'Humanity belongs to Socrates' is about humanity, so it's a different proposition from 'Socrates is human' [Davidson] |
3968 | Propositions explain nothing without an explanation of how sentences manage to name them [Davidson] |
3970 | Thought is only fully developed if we communicate with others [Davidson] |
8870 | Content of thought is established through communication, so knowledge needs other minds [Davidson] |
6179 | Should we assume translation to define truth, or the other way around? [Blackburn on Davidson] |
6399 | Criteria of translation give us the identity of conceptual schemes [Davidson] |
18703 | Davidson's Cogito: 'I think, therefore I am generally right' [Davidson, by Button] |
8869 | The principle of charity attributes largely consistent logic and largely true beliefs to speakers [Davidson] |
3971 | There is simply no alternative to the 'principle of charity' in interpreting what others do [Davidson] |
19154 | The principle of charity says an interpreter must assume the logical constants [Davidson] |
19161 | We indicate use of a metaphor by its obvious falseness, or trivial truth [Davidson] |
7776 | Metaphors just mean what their words literally mean [Davidson] |
7775 | Understanding a metaphor is a creative act, with no rules [Davidson] |
7777 | We accept a metaphor when we see the sentence is false [Davidson] |
20020 | If one action leads directly to another, they are all one action [Davidson, by Wilson/Schpall] |
20072 | We explain an intention by giving an account of acting with an intention [Davidson, by Stout,R] |
20076 | An intending is a judgement that the action is desirable [Davidson] |
20074 | We can keep Davidson's account of intentions in action, by further explaining prior intentions [Davidson, by Stout,R] |
20024 | Davidson gave up reductive accounts of intention, and said it was a primitive [Davidson, by Wilson/Schpall] |
5488 | Regularity theories of causation cannot give an account of human agency [Ellis] |
6385 | The causally strongest reason may not be the reason the actor judges to be best [Davidson] |
5489 | Humans have variable dispositions, and also power to change their dispositions [Ellis] |
20045 | Acting for a reason is a combination of a pro attitude, and a belief that the action is appropriate [Davidson] |
6384 | The notion of cause is essential to acting for reasons, intentions, agency, akrasia, and free will [Davidson] |
20075 | Early Davidson says intentional action is caused by reasons [Davidson, by Stout,R] |
3395 | Davidson claims that what causes an action is the reason for doing it [Davidson, by Kim] |
23734 | The best explanation of reasons as purposes for actions is that they are causal [Davidson, by Smith,M] |
23737 | Reasons can give purposes to actions, without actually causing them [Smith,M on Davidson] |
6664 | Reasons must be causes when agents act 'for' reasons [Davidson, by Lowe] |
19698 | Deviant causal chain: a reason causes an action, but isn't the reason for which it was performed [Davidson, by Neta] |
5490 | Essentialism fits in with Darwinism, but not with extreme politics of left or right [Ellis] |
3973 | Without a teacher, the concept of 'getting things right or wrong' is meaningless [Davidson] |
17465 | Lavoisier's elements included four types of earth [Weisberg/Needham/Hendry] |
5472 | Natural kinds are of objects/substances, or events/processes, or intrinsic natures [Ellis] |
6613 | The natural kinds are objects, processes and properties/relations [Ellis] |
12681 | There are natural kinds of processes [Ellis] |
13583 | There might be uninstantiated natural kinds, such as transuranic elements which have never occurred [Ellis] |
5471 | Essentialism says natural kinds are fundamental to nature, and determine the laws [Ellis] |
13574 | Natural kinds are distinguished by resting on essences [Ellis] |
12680 | Natural kind structures go right down to the bottom level [Ellis] |
8873 | The cause of a usage determines meaning, but why is the microstructure of water relevant? [Davidson] |
5446 | For essentialists two members of a natural kind must be identical [Ellis] |
5480 | The whole of our world is a natural kind, so all worlds like it necessarily have the same laws [Ellis] |
13575 | If there are borderline cases between natural kinds, that makes them superficial [Ellis] |
10371 | Distinguish causation, which is in the world, from explanations, which depend on descriptions [Davidson, by Schaffer,J] |
8403 | Either facts, or highly unspecific events, serve better as causes than concrete events [Field,H on Davidson] |
3524 | Causation is either between events, or between descriptions of events [Davidson, by Maslin] |
3526 | Whether an event is a causal explanation depends on how it is described [Davidson, by Maslin] |
8346 | Full descriptions can demonstrate sufficiency of cause, but not necessity [Davidson] |
4778 | A singular causal statement is true if it is held to fall under a law [Davidson, by Psillos] |
3962 | Cause and effect relations between events must follow strict laws [Davidson] |
5445 | Essentialists regard inanimate objects as genuine causal agents [Ellis] |
5463 | Essentialists believe causation is necessary, resulting from dispositions and circumstances [Ellis] |
5491 | A general theory of causation is only possible in an area if natural kinds are involved [Ellis] |
13595 | Laws don't exist in the world; they are true of the world [Ellis] |
5442 | For 'passivists' behaviour is imposed on things from outside [Ellis] |
5473 | The laws of nature imitate the hierarchy of natural kinds [Ellis] |
5474 | Laws of nature tend to describe ideal things, or ideal circumstances [Ellis] |
5475 | We must explain the necessity, idealisation, ontology and structure of natural laws [Ellis] |
6616 | Least action is not a causal law, but a 'global law', describing a global essence [Ellis] |
12675 | Laws of nature are just descriptions of how things are disposed to behave [Ellis] |
5460 | Causal relations cannot be reduced to regularities, as they could occur just once [Ellis] |
13566 | A proton must have its causal role, because without it it wouldn't be a proton [Ellis] |
13579 | What is most distinctive of scientific essentialism is regarding processes as natural kinds [Ellis] |
13581 | Scientific essentialism is more concerned with explanation than with identity (Locke, not Kripke) [Ellis] |
13594 | The ontological fundamentals are dispositions, and also categorical (spatio-temporal and structural) properties [Ellis] |
5459 | Essentialists say dispositions are basic, rather than supervenient on matter and natural laws [Ellis] |
5461 | The essence of uranium is its atomic number and its electron shell [Ellis] |
6615 | A species requires a genus, and its essence includes the essence of the genus [Ellis] |
13603 | A primary aim of science is to show the limits of the possible [Ellis] |
5464 | For essentialists, laws of nature are metaphysically necessary, being based on essences of natural kinds [Ellis] |
6614 | A hierarchy of natural kinds is elaborate ontology, but needed to explain natural laws [Ellis] |
5487 | Essentialism requires a clear separation of semantics, epistemology and ontology [Ellis] |
6612 | Without general principles, we couldn't predict the behaviour of dispositional properties [Ellis] |
12671 | I deny forces as entities that intervene in causation, but are not themselves causal [Ellis] |
12674 | Energy is the key multi-valued property, vital to scientific realism [Ellis] |
12689 | Simultaneity can be temporal equidistance from the Big Bang [Ellis] |
12690 | The present is the collapse of the light wavefront from the Big Bang [Ellis] |
17469 | 'H2O' just gives the element proportions, not the microstructure [Weisberg/Needham/Hendry] |
17468 | Over 100,000,000 compounds have been discovered or synthesised [Weisberg/Needham/Hendry] |

17467 | Isotopes (such as those of hydrogen) can vary in their rates of chemical reaction [Weisberg/Needham/Hendry] |
17466 | Mendeleev systematised the elements, and also gave an account of their nature [Weisberg/Needham/Hendry] |
