15215 | Philosophy devises and assesses conceptual schemes in the service of worldviews [Harré/Madden] |
15212 | Analysis of concepts based neither on formalism nor psychology can arise from examining what we know [Harré/Madden] |
15210 | Humeans see analysis in terms of formal logic, because necessities are fundamentally logical relations [Harré/Madden] |
15236 | Positivism says science only refers to immediate experiences [Harré/Madden] |
15227 | Logically, definitions have a subject, and a set of necessary predicates [Harré/Madden] |

6299 | Axioms are often affirmed simply because they produce results which have been accepted [Resnik] |
6304 | Mathematical realism says that maths exists, is largely true, and is independent of proofs [Resnik] |
15273 | Points can be 'dense' by unending division, but must meet a tougher criterion to be 'continuous' [Harré/Madden] |
15274 | Points are 'continuous' if any 'cut' point participates in both halves of the cut [Harré/Madden] |
6300 | Mathematical constants and quantifiers only exist as locations within structures or patterns [Resnik] |
6303 | Sets are positions in patterns [Resnik] |
6302 | Structuralism must explain why a triangle is a whole, and not a random set of points [Resnik] |
6295 | There are too many mathematical objects for them all to be mental or physical [Resnik] |
6296 | Maths is pattern recognition and representation, and its truth and proofs are based on these [Resnik] |
6301 | Congruence is the strongest relationship of patterns, equivalence comes next, and mutual occurrence is the weakest [Resnik] |
15211 | There is not an exclusive dichotomy between the formal and the logical [Harré/Madden] |
15261 | Humeans can only explain change with continuity as successive replacement [Harré/Madden] |
15268 | Humeans construct their objects from events, but we construct events from objects [Harré/Madden] |
15257 | The induction problem fades if you work with things, rather than with events [Harré/Madden] |
3473 | Reduction can be of things, properties, ideas or causes [Searle] |
3532 | Solidity in a piston is integral to its structure, not supervenient [Maslin on Searle] |
3533 | Is supervenience just causality? [Searle, by Maslin] |
15300 | Fundamental particulars can't change [Harré/Madden] |
15319 | Hard individual blocks don't fix what 'things' are; fluids are no less material things [Harré/Madden] |
15320 | Magnetic and gravity fields can occupy the same place without merging [Harré/Madden] |
3454 | Reality is entirely particles in force fields [Searle] |
15318 | Gravitational and electrical fields are, for a materialist, distressingly empty of material [Harré/Madden] |
15267 | Events are changes in states of affairs (which consist of structured particulars, with powers and relations) [Harré/Madden] |
15281 | Humeans see predicates as independent, but science says they are connected [Harré/Madden] |
3471 | Some properties depend on components, others on their relations [Searle] |
3472 | Fully 'emergent' properties contradict our whole theory of causation [Searle] |
15279 | Energy was introduced to physics to refer to the 'store of potency' of a moving ball [Harré/Madden] |
15276 | Some powers need a stimulus, but others are just released [Harré/Madden] |
15305 | Some powers are variable, others cannot change (without destroying an identity) [Harré/Madden] |
15218 | Scientists define copper almost entirely (bar atomic number) in terms of its dispositions [Harré/Madden] |
15302 | We explain powers by the natures of things, but explanations end in inexplicable powers [Harré/Madden] |
15303 | Maybe a physical field qualifies as ultimate, if its nature is identical with its powers [Harré/Madden] |
15258 | Powers are not qualities; they just point to directions of empirical investigation [Harré/Madden] |
15315 | What is a field of potentials, if it only consists of possible events? [Harré/Madden] |
15272 | The good criticism of substance by Humeans also loses them the vital concept of a thing [Harré/Madden] |
15304 | We can escape substance and its properties, if we take fields of pure powers as ultimate [Harré/Madden] |
15309 | The assumption that shape and solidity are fundamental implies dubious 'substance' in bodies [Harré/Madden] |
15264 | The notorious substratum results from substance-with-qualities; individuals-with-powers solves this [Harré/Madden] |
15262 | In logic the nature of a kind, substance or individual is the essence which is inseparable from what it is [Harré/Madden] |
15297 | We can infer a new property of a thing from its other properties, via its essential nature [Harré/Madden] |
15266 | We say the essence of particles is energy, but only so we can tell a story about the nature of things [Harré/Madden] |
15220 | To say something remains the same but lacks its capacities and powers seems a contradiction [Harré/Madden] |
15222 | Some individuals can gain or lose capacities or powers, without losing their identity [Harré/Madden] |
15296 | A particular might change all of its characteristics, retaining mere numerical identity [Harré/Madden] |
15275 | 'Dense' time raises doubts about continuous objects, so they need 'continuous' time [Harré/Madden] |
15271 | If things are successive instantaneous events, nothing requires those events to resemble one another [Harré/Madden] |
15256 | Humeans cannot step in the same river twice, because they cannot strictly form the concept of 'river' [Harré/Madden] |
15290 | What reduces the field of the possible is a step towards necessity [Harré/Madden] |
15291 | There is 'absolute' necessity (implied by all propositions) and 'relative' necessity (from what is given) [Harré/Madden] |
15230 | Logical necessity is grounded in the logical form of a statement [Harré/Madden] |
15214 | Natural necessity is not logical necessity or empirical contingency in disguise [Harré/Madden] |
15221 | The relation between what a thing is and what it can do or undergo relate by natural necessity [Harré/Madden] |
15224 | A necessity corresponds to the nature of the actual [Harré/Madden] |
15232 | Natural necessity is when powerful particulars must produce certain results in a situation [Harré/Madden] |
15288 | People doubt science because if it isn't logically necessary it seems to be absolutely contingent [Harré/Madden] |
15289 | Property or event relations are naturally necessary if generated by essential mechanisms [Harré/Madden] |
15231 | Transcendental necessity is conditions of a world required for a rational being to know its nature [Harré/Madden] |
15234 | There is a transcendental necessity for each logical necessity, but the transcendental extends further [Harré/Madden] |
15260 | Counterfactuals are just right for analysing statements about the powers which things have [Harré/Madden] |
15233 | If natural necessity is used to include or exclude some predicate, the predicate is conceptually necessary [Harré/Madden] |
15242 | Having a child is contingent for a 'man', necessary for a 'father'; the latter reflects a necessity of nature [Harré/Madden] |
15216 | Is conceptual necessity just conventional, or does it mirror something about nature? [Harré/Madden] |
15235 | There is a conceptual necessity when properties become a standard part of a nominal essence [Harré/Madden] |
15228 | Necessity and contingency are separate from the a priori and the a posteriori [Harré/Madden] |
15252 | If Goldbach's Conjecture is true (and logically necessary), we may be able to conceive its opposite [Harré/Madden] |
3490 | Beliefs only make sense as part of a network of other beliefs [Searle] |
3491 | Beliefs are part of a network, and also exist against a background [Searle] |
15245 | It is silly to say that direct experience must be justified, either by reason, or by more experience [Harré/Madden] |
15244 | We experience qualities as of objects, not on their own [Harré/Madden] |
3482 | Perception is a function of expectation [Searle] |
15248 | Inference in perception is unconvincingly defended as non-conscious and almost instantaneous [Harré/Madden] |
15269 | Humean impressions are too instantaneous and simple to have structure or relations [Harré/Madden] |
3493 | Memory is mainly a guide for current performance [Searle] |
15286 | Clavius's Paradox: purely syntactic entailment theories won't explain, because they are too profuse [Harré/Madden] |
15283 | Simplicity can sort theories out, but still leaves an infinity of possibilities [Harré/Madden] |
15316 | The powers/natures approach has been so successful (for electricity, magnetism, gravity) it may be universal [Harré/Madden] |
15298 | We prefer the theory which explains and predicts the powers and capacities of particulars [Harré/Madden] |
15225 | Science investigates the nature and constitution of things or substances [Harré/Madden] |
15255 | Conjunctions explain nothing, and so do not give a reason for confidence in inductions [Harré/Madden] |
15270 | Hume's atomic events makes properties independent, and leads to problems with induction [Harré/Madden] |
15284 | Contraposition may be equivalent in truth, but not true in nature, because of irrelevant predicates [Harré/Madden] |
15285 | The items put forward by the contraposition belong within different natural clusters [Harré/Madden] |
15287 | The possibility that all ravens are black is a law depends on a mechanism producing the blackness [Harré/Madden] |
15306 | Only changes require explanation [Harré/Madden] |
15293 | If explanation is by entailment, that lacks a causal direction, unlike natural necessity [Harré/Madden] |
15294 | Powers can explain the direction of causality, and make it a natural necessity [Harré/Madden] |
15254 | If the nature of particulars explains their powers, it also explains their relations and behaviour [Harré/Madden] |
15317 | Powers and natures lead us to hypothesise underlying mechanisms, which may be real [Harré/Madden] |
15310 | Solidity comes from the power of repulsion, and shape from the power of attraction [Harré/Madden] |
15219 | Essence explains passive capacities as well as active powers [Harré/Madden] |
3463 | We don't have a "theory" that other people have minds [Searle] |
3457 | Other minds are not inferred by analogy, but are our best explanation [Searle] |
3480 | We experience unity at an instant and across time [Searle] |
3479 | The mind experiences space, but it is not experienced as spatial [Searle] |
3470 | Conscious creatures seem able to discriminate better [Searle] |
3486 | Unconscious thoughts are those capable of causing conscious ones [Searle] |
3503 | Consciousness results directly from brain processes, not from some intermediary like information [Searle] |
3465 | Either there is intrinsic intentionality, or everything has it [Searle] |
3484 | Water flowing downhill can be described as if it had intentionality [Searle] |
3489 | Intentional phenomena only make sense within a background [Searle] |
3494 | Intentionality is defined in terms of representation [Searle] |
3481 | Consciousness is essential and basic to intentionality [Searle] |
4088 | Pain is not intentional, because it does not represent anything beyond itself [Searle] |
15301 | The very concepts of a particular power or nature imply the possibility of being generalised [Harré/Madden] |
3467 | Neither introspection nor privileged access makes sense [Searle] |
3483 | Introspection is just thinking about mental states, not a special sort of vision [Searle] |
3468 | I cannot observe my own subjectivity [Searle] |
3469 | Mind and brain don't interact if they are the same [Searle] |
3487 | Without internal content, a zombie's full behaviour couldn't be explained [Searle] |

3496 | A program for Chinese translation doesn't need to understand Chinese [Searle] |
3499 | Computation presupposes consciousness [Searle] |
3501 | If we are computers, who is the user? [Searle] |
3456 | Consciousness is a brain property as liquidity is a water property [Searle] |
3453 | Property dualism is the reappearance of Cartesianism [Searle] |
3455 | Property dualists tend to find the mind-body problem baffling [Searle] |
3475 | Property dualism denies reductionism [Searle] |
3476 | Mind and brain are supervenient in respect of cause and effect [Searle] |
3477 | If mind-brain supervenience isn't causal, this implies epiphenomenalism [Searle] |
3531 | Mental events can cause even though supervenient, like the solidity of a piston [Searle] |
3478 | Upwards mental causation makes 'supervenience' irrelevant [Searle] |
3466 | Consciousness seems indefinable by conditions or categories [Searle] |
3500 | Can the homunculus fallacy be beaten by recursive decomposition? [Searle] |
9317 | Searle argues that biology explains consciousness, but physics won't explain biology [Searle, by Kriegel/Williford] |
3474 | If mind is caused by brain, does this mean mind IS brain? [Searle] |
3497 | If mind is multiply realisable, it is possible that anything could realise it [Searle] |
3462 | We don't postulate folk psychology, we experience it [Searle] |
3498 | Computation isn't a natural phenomenon, it is a way of seeing phenomena [Searle] |
3492 | Content is much more than just sentence meaning [Searle] |
15226 | What properties a thing must have to be a type of substance can be laid down a priori [Harré/Madden] |
3464 | There is no such thing as 'wide content' [Searle] |
3506 | We explain behaviour in terms of actual internal representations in the agent [Searle] |
3451 | Meaning is derived intentionality [Searle] |
3450 | Philosophy of language is a branch of philosophy of mind [Searle] |
3507 | Universal grammar doesn't help us explain anything [Searle] |
15229 | We say there is 'no alternative' in all sorts of contexts, and there are many different grounds for it [Harré/Madden] |
3495 | Shared Background makes translation possible, though variation makes it hard [Searle] |
3505 | The function of a heart depends on what we want it to do [Searle] |
3504 | Chemistry entirely explains plant behaviour [Searle] |
15292 | We can base the idea of a natural kind on the mechanisms that produce natural necessity [Harré/Madden] |
15299 | Species do not have enough constancy to be natural kinds [Harré/Madden] |
15253 | If the concept of a cause includes its usual effects, we call it a 'power' [Harré/Madden] |
15278 | Humean accounts of causal direction by time fail, because cause and effect can occur together [Harré/Madden] |
15246 | Active causal power is just objects at work, not something existing in itself [Harré/Madden] |
15213 | Causation always involves particular productive things [Harré/Madden] |
15217 | Efficient causes combine stimulus to individuals, absence of contraints on activity [Harré/Madden] |
15277 | The cause (or part of it) is what stimulates or releases the powerful particular thing involved [Harré/Madden] |
15237 | Originally Humeans based lawlike statements on pure qualities, without particulars [Harré/Madden] |
15238 | Being lawlike seems to resist formal analysis, because there are always counter-examples [Harré/Madden] |
15223 | Necessary effects will follow from some general theory specifying powers and structure of a world [Harré/Madden] |
15241 | Humeans say there is no necessity in causation, because denying an effect is never self-contradictory [Harré/Madden] |
15240 | In lawful universal statements (unlike accidental ones) we see why the regularity holds [Harré/Madden] |
15239 | We could call any generalisation a law, if it had reasonable support and no counter-evidence [Harré/Madden] |
15243 | We perceive motion, and not just successive occupations of different positions [Harré/Madden] |
15265 | 'Energy' is a quasi-substance invented as the bearer of change during interactions [Harré/Madden] |
15280 | 'Kinetic energy' is used to explain the effects of moving things when they are stopped [Harré/Madden] |
15321 | Space can't be an individual (in space), but it is present in all places [Harré/Madden] |
15259 | Chemical atoms have two powers: to enter certain combinations, and to emit a particular spectrum [Harré/Madden] |
15263 | Chemistry is not purely structural; CO2 is not the same as SO2 [Harré/Madden] |
3502 | Mind involves fighting, fleeing, feeding and fornicating [Searle] |
3459 | You can only know the limits of knowledge if you know the other side of the limit [Searle] |
15295 | Theism is supposed to make the world more intelligible - and should offer results [Harré/Madden] |
