| 15227 | Logically, definitions have a subject, and a set of necessary predicates [Harré/Madden] |
| 15273 | Points can be 'dense' by unending division, but must meet a tougher criterion to be 'continuous' [Harré/Madden] |

| 15318 | Gravitational and electrical fields are, for a materialist, distressingly empty of material [Harré/Madden] |
| 15809 | A state of affairs pertains to a thing if it implies that it has some property [Chisholm] |
| 15828 | I propose that events and propositions are two types of states of affairs [Chisholm] |
| 15267 | Events are changes in states of affairs (which consist of structured particulars, with powers and relations) [Harré/Madden] |

| 15303 | Maybe a physical field qualifies as ultimate, if its nature is identical with its powers [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] |
| 15814 | A peach is sweet and fuzzy, but it doesn't 'have' those qualities [Chisholm] |

| 15808 | A traditional individual essence includes all of a thing's necessary characteristics [Chisholm] |
| 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] |
| 11966 | If there are essential properties, how do you find out what they are? [Chisholm] |
| 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] |

| 15826 | There is 'loose' identity between things if their properties, or truths about them, might differ [Chisholm] |
| 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] |
| 15221 | The relation between what a thing is and what it can do or undergo relate by natural necessity [Harré/Madden] |
| 15214 | Natural necessity is not logical necessity or empirical contingency in disguise [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] |

| 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] |

| 15248 | Inference in perception is unconvincingly defended as non-conscious and almost instantaneous [Harré/Madden] |
| 15816 | 'I feel depressed' is more like 'he runs slowly' than like 'he has a red book' [Chisholm] |
| 15817 | If we can say a man senses 'redly', why not also 'rectangularly'? [Chisholm] |
| 15818 | So called 'sense-data' are best seen as 'modifications' of the person experiencing them [Chisholm] |
| 15269 | Humean impressions are too instantaneous and simple to have structure or relations [Harré/Madden] |
| 8790 | The 'doctrine of the given' is correct; some beliefs or statements are self-justifying [Chisholm] |

| 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] |

| 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] |
| 15831 | Explanations have states of affairs as their objects [Chisholm] |
| 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] |

| 15301 | The very concepts of a particular power or nature imply the possibility of being generalised [Harré/Madden] |
| 15811 | I am picked out uniquely by my individual essence, which is 'being identical with myself' [Chisholm] |

| 15299 | Species do not have enough constancy to be natural kinds [Harré/Madden] |
| 15823 | Some propose a distinct 'agent causation', as well as 'event causation' [Chisholm] |
| 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] |

| 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] |
