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] |

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] |

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] |

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] |
13602 | We cannot form an idea of a 'power', and the word is without meaning [Hume] |
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] |
2216 | We transfer the frequency of past observations to our future predictions [Hume] |
2215 | There is no such thing as chance [Hume] |
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] |
2209 | Belief is stronger, clearer and steadier than imagination [Hume] |
2207 | Belief can't be a concept plus an idea, or we could add the idea to fictions [Hume] |
2208 | Belief is just a particular feeling attached to ideas of objects [Hume] |
2213 | Beliefs are built up by resemblance, contiguity and causation [Hume] |
3661 | 'Natural beliefs' are unavoidable, whatever our judgements [Hume, by Strawson,G] |
15245 | It is silly to say that direct experience must be justified, either by reason, or by more experience [Harré/Madden] |
2191 | Relations of ideas are known by thought, independently from the world [Hume] |
2239 | If secondary qualities (e.g. hardness) are in the mind, so are primary qualities like extension [Hume] |
2237 | It never occurs to people that they only experience representations, not the real objects [Hume] |
15244 | We experience qualities as of objects, not on their own [Harré/Madden] |
15248 | Inference in perception is unconvincingly defended as non-conscious and almost instantaneous [Harré/Madden] |
2184 | All ideas are copies of impressions [Hume] |
23631 | Hume is loose when he says perceptions of different strength are different species [Reid on Hume] |
2192 | All reasoning about facts is causal; nothing else goes beyond memory and senses [Hume] |
2182 | Impressions are our livelier perceptions, Ideas the less lively ones [Hume] |
2190 | All objects of enquiry are Relations of Ideas, or Matters of Fact [Hume] |
2246 | If books don't relate ideas or explain facts, commit them to the flames [Hume] |
2189 | All ideas are connected by Resemblance, Contiguity in time or place, and Cause and Effect [Hume] |
15269 | Humean impressions are too instantaneous and simple to have structure or relations [Harré/Madden] |
2194 | How could Adam predict he would drown in water or burn in fire? [Hume] |
2183 | We can only invent a golden mountain by combining experiences [Hume] |

3902 | Hume mistakenly lumps sensations and perceptions together as 'impressions' [Scruton on Hume] |
2206 | Reasons for belief must eventually terminate in experience, or they are without foundation [Hume] |
2235 | There is no certain supreme principle, or infallible rule of inference [Hume] |
10328 | We think testimony matches reality because of experience, not some a priori connection [Hume] |
2230 | Good testimony needs education, integrity, motive and agreement [Hume, by PG] |
2238 | Reason can never show that experiences are connected to external objects [Hume] |
2242 | Mitigated scepticism draws attention to the limitations of human reason, and encourages modesty [Hume] |
2243 | Mitigated scepticism sensibly confines our enquiries to the narrow capacity of human understanding [Hume] |
2236 | Examples of illusion only show that sense experience needs correction by reason [Hume] |
2240 | It is a very extravagant aim of the sceptics to destroy reason and argument by means of reason and argument [Hume] |
2241 | The main objection to scepticism is that no good can come of it [Hume] |
335 | Do the gods also hold different opinions about what is right and honourable? [Plato] |
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] |
2198 | We assume similar secret powers behind similar experiences, such as the nourishment of bread [Hume] |
2201 | Induction can't prove that the future will be like the past, since induction assumes this [Hume] |
2203 | If we infer causes from repetition, this explains why we infer from a thousand objects what we couldn't infer from one [Hume] |
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] |

6350 | Premises can support an argument without entailing it [Pollock/Cruz on Hume] |
3598 | Hume just shows induction isn't deduction [Williams,M on Hume] |
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] |
15301 | The very concepts of a particular power or nature imply the possibility of being generalised [Harré/Madden] |
2210 | A picture of a friend strengthens our idea of him, by resemblance [Hume] |
17712 | General ideas are the connection by resemblance to some particular [Hume] |
8544 | Hume does not distinguish real resemblances among degrees of resemblance [Shoemaker on Hume] |
2211 | When I am close to (contiguous with) home, I feel its presence more nearly [Hume] |
2212 | An object made by a saint is the best way to produce thoughts of him [Hume] |
2214 | Our awareness of patterns of causation is too important to be left to slow and uncertain reasoning [Hume] |
2222 | The doctrine of free will arises from a false sensation we have of freedom in many actions [Hume] |
2223 | Liberty is merely acting according to the will, which anyone can do if they are not in chains [Hume] |
3655 | Hume makes determinism less rigid by removing the necessity from causation [Trusted on Hume] |
15226 | What properties a thing must have to be a type of substance can be laid down a priori [Harré/Madden] |
15229 | We say there is 'no alternative' in all sorts of contexts, and there are many different grounds for it [Harré/Madden] |
2220 | Only experience teaches us about our wills [Hume] |
2224 | Praise and blame can only be given if an action proceeds from a person's character and disposition [Hume] |
2225 | If you deny all necessity and causation, then our character is not responsible for our crime [Hume] |
2226 | Repentance gets rid of guilt, which shows that responsibility arose from the criminal principles in the mind [Hume] |
2233 | No government has ever suffered by being too tolerant of philosophy [Hume] |
2195 | We can discover some laws of nature, but never its ultimate principles and causes [Hume] |
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] |
2245 | A priori it looks as if a cause could have absolutely any effect [Hume] |
4772 | If a singular effect is studied, its cause can only be inferred from the types of events involved [Hume] |
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] |
8341 | Hume never even suggests that there is no such thing as causation [Hume, by Strawson,G] |
15213 | Causation always involves particular productive things [Harré/Madden] |
8344 | At first Hume said qualities are the causal entities, but later he said events [Hume, by Davidson] |
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] |
3662 | Hume says we can only know constant conjunctions, not that that's what causation IS [Hume, by Strawson,G] |
4771 | In both of Hume's definitions, causation is extrinsic to the sequence of events [Psillos on Hume] |
5194 | Hume's definition of cause as constantly joined thoughts can't cover undiscovered laws [Ayer on Hume] |
2221 | A cause is either similar events following one another, or an experience always suggesting a second experience [Hume] |
2193 | No causes can be known a priori, but only from experience of constant conjunctions [Hume] |
2234 | It is only when two species of thing are constantly conjoined that we can infer one from the other [Hume] |
8422 | Cause is where if the first object had not been, the second had not existed [Hume] |
2218 | In observing causes we can never observe any necessary connections or binding qualities [Hume] |
15249 | Hume never shows how a strong habit could generate the concept of necessity [Harré/Madden on Hume] |
8339 | Hume's regularity theory of causation is epistemological; he believed in some sort of natural necessity [Hume, by Strawson,G] |
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] |
337 | It seems that the gods love things because they are pious, rather than making them pious by loving them [Plato] |
336 | Is what is pious loved by the gods because it is pious, or is it pious because they love it? (the 'Euthyphro Question') [Plato] |
2244 | It can never be a logical contradiction to assert the non-existence of something thought to exist [Hume] |
2232 | You can't infer the cause to be any greater than its effect [Hume] |
2228 | All experience must be against a supposed miracle, or it wouldn't be called 'a miracle' [Hume] |
2229 | To establish a miracle the falseness of the evidence must be a greater miracle than the claimed miraculous event [Hume] |
2227 | A miracle violates laws which have been established by continuous unchanging experience, so should be ignored [Hume] |
2185 | The idea of an infinite, intelligent, wise and good God arises from augmenting the best qualities of our own minds [Hume] |
15295 | Theism is supposed to make the world more intelligible - and should offer results [Harré/Madden] |
