| 7623 | For ancient Greeks being wise was an ethical value [Putnam] |
| 2352 | The job of the philosopher is to distinguish facts about the world from conventions [Putnam] |
| 2319 | Metaphysics is the clarification of the ontological relationships between different areas of thought [Kim] |
| 6782 | Realism is the only philosophy of science that doesn't make the success of science a miracle [Putnam] |
| 6267 | A culture needs to admit that knowledge is more extensive than just 'science' [Putnam] |
| 6272 | 'True' and 'refers' cannot be made scientically precise, but are fundamental to science [Putnam] |
| 3426 | If one theory is reduced to another, we make fewer independent assumptions about the world [Kim] |
| 6276 | 'The rug is green' might be warrantedly assertible even though the rug is not green [Putnam] |
| 4714 | Putnam's epistemic notion of truth replaces the realism of correspondence with ontological relativism [Putnam, by O'Grady] |
| 6266 | We need the correspondence theory of truth to understand language and science [Putnam] |
| 7617 | Before Kant, all philosophers had a correspondence theory of truth [Putnam] |
| 6277 | Correspondence between concepts and unconceptualised reality is impossible [Putnam] |
| 4716 | The correspondence theory is wrong, because there is no one correspondence between reality and fact [Putnam, by O'Grady] |
| 8828 | Truth is rational acceptability [Putnam] |
| 7616 | Truth is an idealisation of rational acceptability [Putnam] |
| 18951 | For scientific purposes there is a precise concept of 'true-in-L', using set theory [Putnam] |
| 6264 | In Tarski's definition, you understand 'true' if you accept the notions of the object language [Putnam] |
| 6265 | Tarski has given a correct account of the formal logic of 'true', but there is more to the concept [Putnam] |
| 6269 | Only Tarski has found a way to define 'true' [Putnam] |
| 2345 | Semantic notions do not occur in Tarski's definitions, but assessing their correctness involves translation [Putnam] |
| 2347 | Asserting the truth of an indexical statement is not the same as uttering the statement [Putnam] |
| 18953 | Modern notation frees us from Aristotle's restriction of only using two class-names in premises [Putnam] |
| 18949 | The universal syllogism is now expressed as the transitivity of subclasses [Putnam] |
| 18952 | '⊃' ('if...then') is used with the definition 'Px ⊃ Qx' is short for '¬(Px & ¬Qx)' [Putnam] |
| 18958 | In type theory, 'x ∈ y' is well defined only if x and y are of the appropriate type [Putnam] |
| 9944 | We understand some statements about all sets [Putnam] |
| 13655 | The Löwenheim-Skolem theorems show that whether all sets are constructible is indeterminate [Putnam, by Shapiro] |
| 9915 | V = L just says all sets are constructible [Putnam] |
| 18954 | Before the late 19th century logic was trivialised by not dealing with relations [Putnam] |
| 18956 | Asserting first-order validity implicitly involves second-order reference to classes [Putnam] |

| 10066 | Putnam coined the term 'if-thenism' [Putnam, by Musgrave] |
| 18961 | We can identify functions with certain sets - or identify sets with certain functions [Putnam] |
| 17505 | Using proper names properly doesn't involve necessary and sufficient conditions [Putnam] |
| 18955 | Having a valid form doesn't ensure truth, as it may be meaningless [Putnam] |
| 14203 | Intension is not meaning, as 'cube' and 'square-faced polyhedron' are intensionally the same [Putnam] |
| 14207 | If cats equal cherries, model theory allows reinterpretation of the whole language preserving truth [Putnam] |
| 9913 | The Löwenheim-Skolem Theorem is close to an antinomy in philosophy of language [Putnam] |
| 18959 | Sets larger than the continuum should be studied in an 'if-then' spirit [Putnam] |
| 18200 | Very large sets should be studied in an 'if-then' spirit [Putnam] |
| 9937 | I do not believe mathematics either has or needs 'foundations' [Putnam] |
| 9939 | It is conceivable that the axioms of arithmetic or propositional logic might be changed [Putnam] |
| 3663 | How can you contemplate Platonic entities without causal transactions with them? [Putnam] |
| 9940 | Maybe mathematics is empirical in that we could try to change it [Putnam] |
| 9914 | It is unfashionable, but most mathematical intuitions come from nature [Putnam] |
| 9941 | Science requires more than consistency of mathematics [Putnam] |
| 18199 | Indispensability strongly supports predicative sets, and somewhat supports impredicative sets [Putnam] |
| 8857 | We must quantify over numbers for science; but that commits us to their existence [Putnam] |
| 4779 | For Kim, events are exemplifications of properties by objects at particular times [Kim, by Psillos] |
| 10369 | How fine-grained Kim's events are depends on how finely properties are individuated [Kim, by Schaffer,J] |
| 8976 | If events are ordered triples of items, such things seem to be sets, and hence abstract [Simons on Kim] |
| 8975 | Events cannot be merely ordered triples, but must specify the link between the elements [Kim, by Simons] |
| 8974 | Events are composed of an object with an attribute at a time [Kim, by Simons] |
| 8977 | Since properties like self-identity and being 2+2=4 are timeless, Kim must restrict his properties [Simons on Kim] |
| 8980 | Kim's theory results in too many events [Simons on Kim] |
| 2317 | Reductionism is good on light, genes, temperature and transparency [Kim, by PG] |
| 3536 | Supervenient properties must have matching base properties [Kim] |
| 2310 | Supervenience is linked to dependence [Kim] |
| 2315 | Mereological supervenience says wholes are fixed by parts [Kim] |
| 13745 | Supervenience is not a dependence relation, on the lines of causal, mereological or semantic dependence [Kim] |
| 13746 | Supervenience is just a 'surface' relation of pattern covariation, which still needs deeper explanation [Kim] |
| 3431 | Supervenience suggest dependence without reduction (e.g. beauty) [Kim] |
| 6280 | Realism is a theory, which explains the convergence of science and the success of language [Putnam] |
| 17644 | Metaphysical realism is committed to there being one ultimate true theory [Putnam] |
| 2349 | Realists believe truth is correspondence, independent of humans, is bivalent, and is unique [Putnam] |
| 2329 | Causal power is a good way of distinguishing the real from the unreal [Kim] |
| 9943 | You can't deny a hypothesis a truth-value simply because we may never know it! [Putnam] |
| 22181 | Putnam says anti-realism is a bad explanation of accurate predictions [Putnam, by Okasha] |
| 14214 | If we try to cure the abundance of theories with causal links, this is 'just more theory' [Putnam, by Lewis] |
| 17648 | It is an illusion to think there could be one good scientific theory of reality [Putnam] |
| 14205 | The sentence 'A cat is on a mat' remains always true when 'cat' means cherry and 'mat' means tree [Putnam] |
| 3437 | 'Physical facts determine all the facts' is the physicalists' slogan [Kim] |
| 7610 | A fact is simply what it is rational to accept [Putnam] |
| 15456 | Extrinsic properties, unlike intrinsics, imply the existence of a separate object [Kim, by Lewis] |
| 3430 | Resemblance or similarity is the core of our concept of a property [Kim] |
| 3432 | Is weight a 'resultant' property of water, but transparency an 'emergent' property? [Kim] |
| 2320 | Properties can have causal powers lacked by their constituents [Kim] |
| 3434 | Emergent properties are 'brute facts' (inexplicable), but still cause things [Kim] |
| 7618 | Very nominalistic philosophers deny properties, though scientists accept them [Putnam] |
| 3436 | Should properties be individuated by their causal powers? [Kim] |
| 18957 | Nominalism only makes sense if it is materialist [Putnam] |
| 2351 | Aristotle says an object (e.g. a lamp) has identity if its parts stay together when it is moved [Putnam] |
| 18950 | Physics is full of non-physical entities, such as space-vectors [Putnam] |
| 17643 | Shape is essential relative to 'statue', but not essential relative to 'clay' [Putnam] |
| 11908 | Putnam bases essences on 'same kind', but same kinds may not share properties [Mackie,P on Putnam] |
| 18890 | Putnam smuggles essentialism about liquids into his proof that water must be H2O [Salmon,N on Putnam] |
| 4718 | If necessity is always relative to a description in a language, then there is only 'de dicto' necessity [Putnam, by O'Grady] |
| 10269 | Mathematics eliminates possibility, as being simultaneous actuality in sets [Putnam] |
| 3406 | Counterfactuals are either based on laws, or on nearby possible worlds [Kim, by PG] |
| 9169 | A statement can be metaphysically necessary and epistemologically contingent [Putnam] |
| 5819 | Conceivability is no proof of possibility [Putnam] |
| 6284 | If a tautology is immune from revision, why would that make it true? [Putnam] |
| 17642 | The old view that sense data are independent of mind is quite dotty [Putnam] |
| 8825 | It seems impossible to logically deduce physical knowledge from indubitable sense data [Kim] |
| 6273 | Knowledge depends on believing others, which must be innate, as inferences are not strong enough [Putnam] |
| 6274 | Empathy may not give knowledge, but it can give plausibility or right opinion [Putnam] |
| 530 | There are two contradictory arguments about everything [Kim] |
| 13314 | Protagoras says arguments on both sides are always equal [Kim, by Seneca] |
| 7620 | Some kind of objective 'rightness' is a presupposition of thought itself [Putnam] |
| 2065 | Not every person is the measure of all things, but only wise people [Plato on Kim] |
| 1550 | Why didn't Protagoras begin by saying "a tadpole is the measure of all things"? [Plato on Kim] |
| 18960 | Most predictions are uninteresting, and are only sought in order to confirm a theory [Putnam] |
| 17508 | Science aims at truth, not at 'simplicity' [Putnam] |
| 14204 | Naïve operationalism would have meanings change every time the tests change [Putnam] |
| 14470 | Explanatory exclusion: there cannot be two separate complete explanations of a single event [Kim] |
| 17084 | You can't decide which explanations are good if you don't attend to the interest-relative aspects [Putnam] |
| 3368 | Mind is basically qualities and intentionality, but how do they connect? [Kim] |
| 3392 | Mind is only interesting if it has causal powers [Kim] |
| 3396 | Experiment requires mental causation [Kim] |
| 2318 | Agency, knowledge, reason, memory, psychology all need mental causes [Kim, by PG] |
| 3397 | Beliefs cause other beliefs [Kim] |
| 3367 | Both thought and language have intentionality [Kim] |
| 3365 | Intentionality involves both reference and content [Kim] |
| 2325 | It seems impossible that an exact physical copy of this world could lack intentionality [Kim] |
| 3360 | Are pains pure qualia, or do they motivate? [Kim] |
| 7705 | The Twin Earth theory suggests that intentionality is independent of qualia [Jacquette on Putnam] |
| 3366 | Pain has no reference or content [Kim] |
| 3389 | Inverted qualia and zombies suggest experience isn't just functional [Kim] |
| 3391 | Crosswiring would show that pain and its function are separate [Kim, by PG] |
| 3422 | Externalism about content makes introspection depend on external evidence [Kim] |
| 3412 | How do we distinguish our anger from embarrassment? [Kim] |
| 3363 | We often can't decide what emotion, or even sensation, we are experiencing [Kim] |
| 3409 | Mental substance causation makes physics incomplete [Kim] |
| 3399 | If epiphenomenalism were true, we couldn't report consciousness [Kim] |
| 3390 | Are inverted or absent qualia coherent ideas? [Kim] |
| 3414 | What could demonstrate that zombies and inversion are impossible? [Kim] |
| 3359 | Cartesian dualism fails because it can't explain mental causation [Kim] |
| 3369 | Logical behaviourism translates mental language to behavioural [Kim] |
| 3428 | Behaviourism reduces mind to behaviour via bridging principles [Kim] |
| 2590 | Dispositions need mental terms to define them [Putnam] |
| 3380 | Are dispositions real, or just a type of explanation? [Kim] |
| 3460 | Superactors and superspartans count against behaviourism [Putnam, by Searle] |
| 2591 | Total paralysis would mean that there were mental states but no behaviour at all [Putnam] |
| 3371 | Behaviour depends on lots of mental states together [Kim] |
| 3372 | Behaviour is determined by society as well as mental states [Kim] |
| 3373 | Snakes have different pain behaviour from us [Kim] |
| 3370 | What behaviour goes with mathematical beliefs? [Kim] |
| 2592 | Functional states correlate with AND explain pain behaviour [Putnam] |
| 3379 | Neurons seem to be very similar and interchangeable [Kim] |
| 2324 | Intentionality as function seems possible [Kim] |
| 2589 | Functionalism is compatible with dualism, as pure mind could perform the functions [Putnam] |
| 2588 | Is pain a functional state of a complete organism? [Putnam] |
| 3388 | Machine functionalism requires a Turing machine, causal-theoretical version doesn't [Kim] |
| 5495 | Instances of pain are physical tokens, but the nature of pain is more abstract [Putnam, by Lycan] |
| 2331 | Functionalism says robots and people are the same at one level of abstraction [Putnam] |
| 3384 | The person couldn't run Searle's Chinese Room without understanding Chinese [Kim] |
| 2071 | If concepts have external meaning, computational states won't explain psychology [Putnam] |
| 2332 | Functionalism can't explain reference and truth, which are needed for logic [Putnam] |
| 3393 | How do functional states give rise to mental causation? [Kim] |
| 2348 | Is there just one computational state for each specific belief? [Putnam] |
| 3427 | Reductionism is impossible if there aren't any 'bridge laws' between mental and physical [Kim] |
| 2314 | Maybe intentionality is reducible, but qualia aren't [Kim] |
| 3439 | Reductionism gets stuck with qualia [Kim] |
| 3424 | Most modern physicalists are non-reductive property dualists [Kim] |
| 2587 | Temperature is mean molecular kinetic energy, but they are two different concepts [Putnam] |
| 3376 | We can't assess evidence about mind without acknowledging phenomenal properties [Kim] |
| 2313 | Emergentism says there is no explanation for a supervenient property [Kim] |
| 2328 | The only mental property that might be emergent is that of qualia [Kim] |
| 2309 | Non-Reductive Physicalism relies on supervenience [Kim] |
| 3362 | Supervenience says all souls are identical, being physically indiscernible [Kim] |
| 3413 | Zombies and inversion suggest non-reducible supervenience [Kim] |
| 2311 | Maybe strong supervenience implies reduction [Kim] |
| 3374 | Token physicalism isn't reductive; it just says all mental events have some physical properties [Kim] |
| 3433 | The core of the puzzle is the bridge laws between mind and brain [Kim] |
| 2344 | If we are going to eliminate folk psychology, we must also eliminate folk logic [Putnam] |
| 3377 | Elimination can either be by translation or by causal explanation [Kim] |
| 3438 | Reductionists deny new causal powers at the higher level [Kim] |
| 3440 | Without reductionism, mental causation is baffling [Kim] |
| 2308 | Identity theory was overthrown by multiple realisations and causal anomalies [Kim] |
| 6376 | Neuroscience does not support multiple realisability, and tends to support identity [Polger on Putnam] |
| 2330 | If humans and molluscs both feel pain, it can't be a single biological state [Putnam, by Kim] |
| 2322 | Multiple realisation applies to other species, and even one individual over time [Kim] |
| 2327 | Knowledge and inversion make functionalism about qualia doubtful [Kim] |
| 3375 | If an orange image is a brain state, are some parts of the brain orange? [Kim] |
| 3411 | How do we distinguish our attitudes from one another? [Kim] |
| 2323 | Emotions have both intentionality and qualia [Kim] |
| 3386 | Folk psychology has been remarkably durable [Kim] |
| 3394 | Maybe folk psychology is a simulation, not a theory [Kim] |
| 2074 | Can we give a scientific, computational account of folk psychology? [Putnam] |
| 3387 | A culture without our folk psychology would be quite baffling [Kim] |
| 3410 | Folk psychology has adapted to Freudianism [Kim] |
| 7611 | Rationality is one part of our conception of human flourishing [Putnam] |
| 2605 | If everything uses mentalese, ALL concepts must be innate! [Putnam] |
| 2606 | No machine language can express generalisations [Putnam] |
| 3382 | A machine with a mind might still fail the Turing Test [Kim] |
| 3383 | The Turing Test is too specifically human in its requirements [Kim] |
| 4099 | If Twins talking about 'water' and 'XYZ' have different thoughts but identical heads, then thoughts aren't in the head [Putnam, by Crane] |
| 12026 | We say ice and steam are different forms of water, but not that they are different forms of H2O [Forbes,G on Putnam] |
| 3208 | Does 'water' mean a particular substance that was 'dubbed'? [Putnam, by Rey] |
| 14200 | 'Water' on Twin Earth doesn't refer to water, but no mental difference can account for this [Putnam] |
| 3408 | Two identical brain states could have different contents in different worlds [Kim] |
| 2343 | Reference may be different while mental representation is the same [Putnam] |
| 3420 | Two types of water are irrelevant to accounts of behaviour [Kim] |
| 9168 | I can't distinguish elm trees, but I mean by 'elm' the same set of trees as everybody else [Putnam] |
| 5820 | 'Water' has an unnoticed indexical component, referring to stuff around here [Putnam] |
| 7612 | Reference is social not individual, because we defer to experts when referring to elm trees [Putnam] |
| 3418 | 'Arthritis in my thigh' requires a social context for its content to be meaningful [Kim] |
| 3421 | Content is best thought of as truth conditions [Kim] |
| 3416 | Content may match several things in the environment [Kim] |
| 3419 | Pain, our own existence, and negative existentials, are not external [Kim] |
| 3417 | Content depends on other content as well as the facts [Kim] |
| 7613 | Concepts are (at least in part) abilities and not occurrences [Putnam] |
| 6282 | Theory of meaning presupposes theory of understanding and reference [Putnam] |
| 2346 | Meaning and translation (which are needed to define truth) both presuppose the notion of reference [Putnam] |
| 6281 | Truth conditions can't explain understanding a sentence, because that in turn needs explanation [Putnam] |
| 6278 | We should reject the view that truth is prior to meaning [Putnam] |
| 2354 | "Meaning is use" is not a definition of meaning [Putnam] |
| 2336 | Holism seems to make fixed definition more or less impossible [Putnam] |
| 2334 | Meaning holism tried to show that you can't get fixed meanings built out of observation terms [Putnam] |
| 2335 | Understanding a sentence involves background knowledge and can't be done in isolation [Putnam] |
| 6271 | How reference is specified is not what reference is [Putnam] |
| 2340 | We should separate how the reference of 'gold' is fixed from its conceptual content [Putnam] |
| 2341 | Like names, natural kind terms have their meaning fixed by extension and reference [Putnam] |
| 17506 | I now think reference by the tests of experts is a special case of being causally connected [Putnam] |
| 2338 | Reference (say to 'elms') is a social phenomenon which we can leave to experts [Putnam] |
| 14202 | Neither individual nor community mental states fix reference [Putnam] |
| 9170 | We need to recognise the contribution of society and of the world in determining reference [Putnam] |
| 14201 | Maybe the total mental state of a language community fixes the reference of a term [Putnam] |
| 2339 | Aristotle implies that we have the complete concepts of a language in our heads, but we don't [Putnam] |
| 3893 | Often reference determines sense, and not (as Frege thought) vice versa [Putnam, by Scruton] |
| 6268 | The claim that scientific terms are incommensurable can be blocked if scientific terms are not descriptions [Putnam] |
| 5817 | Language is more like a cooperative steamship than an individual hammer [Putnam] |
| 6279 | A private language could work with reference and beliefs, and wouldn't need meaning [Putnam] |
| 6270 | The correct translation is the one that explains the speaker's behaviour [Putnam] |
| 6283 | Language maps the world in many ways (because it maps onto other languages in many ways) [Putnam] |
| 14206 | There are infinitely many interpretations of a sentence which can all seem to be 'correct' [Putnam] |
| 3403 | We assume people believe the obvious logical consequences of their known beliefs [Kim] |
| 3402 | If someone says "I do and don't like x", we don't assume a contradiction [Kim] |
| 6275 | You can't say 'most speaker's beliefs are true'; in some areas this is not so, and you can't count beliefs [Putnam] |
| 7624 | The word 'inconsiderate' nicely shows the blurring of facts and values [Putnam] |
| 6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
| 11191 | The hidden structure of a natural kind determines membership in all possible worlds [Putnam] |
| 17507 | Natural kind stereotypes are 'strong' (obvious, like tiger) or 'weak' (obscure, like molybdenum) [Putnam] |
| 11904 | Express natural kinds as a posteriori predicate connections, not as singular terms [Putnam, by Mackie,P] |
| 2342 | "Water" is a natural kind term, but "H2O" is a description [Putnam] |
| 8430 | Causal statements are used to explain, to predict, to control, to attribute responsibility, and in theories [Kim] |
| 3535 | All observable causes are merely epiphenomena [Kim] |
| 17645 | An alien might think oxygen was the main cause of a forest fire [Putnam] |
| 3401 | A common view is that causal connections must be instances of a law [Kim] |
| 8396 | Many counterfactuals have nothing to do with causation [Kim, by Tooley] |
| 8429 | Counterfactuals can express four other relations between events, apart from causation [Kim] |
| 8428 | Causation is not the only dependency relation expressed by counterfactuals [Kim] |
| 3407 | Laws are either 'strict', or they involve a 'ceteris paribus' clause [Kim] |
| 11192 | If causes are the essence of diseases, then disease is an example of a relational essence [Putnam, by Williams,NE] |
| 11190 | Archimedes meant by 'gold' the hidden structure or essence of the stuff [Putnam] |
| 5818 | If water is H2O in the actual world, there is no possible world where it isn't H2O [Putnam] |
| 4781 | Many counterfactual truths do not imply causation ('if yesterday wasn't Monday, it isn't Tuesday') [Kim, by Psillos] |
