19033 | Deontic modalities are 'ought-to-be', for sentences, and 'ought-to-do' for predicates [Vetter] |

19024 | A determinate property must be a unique instance of the determinable class [Vetter] |
19021 | I have an 'iterated ability' to learn the violin - that is, the ability to acquire that ability [Vetter] |
19016 | We should think of dispositions as 'to do' something, not as 'to do something, if ....' [Vetter] |
19017 | Nomological dispositions (unlike ordinary ones) have to be continually realised [Vetter] |
19014 | How can spatiotemporal relations be understood in dispositional terms? [Vetter] |
223 | If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato] |
227 | You must always mean the same thing when you utter the same name [Plato] |

210 | It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato] |
220 | The concept of a master includes the concept of a slave [Plato] |
212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
216 | If things are made alike by participating in something, that thing will be the absolute idea [Plato] |
215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato] |
218 | Participation is not by means of similarity, so we are looking for some other method of participation [Plato] |
214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato] |
217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |

15850 | Anything which has parts must be one thing, and parts are of a one, not of a many [Plato] |
13259 | It seems that the One must be composed of parts, which contradicts its being one [Plato] |
19030 | Why does origin matter more than development; why are some features of origin more important? [Vetter] |
19040 | We take origin to be necessary because we see possibilities as branches from actuality [Vetter] |
15847 | Two things relate either as same or different, or part of a whole, or the whole of the part [Plato] |
19008 | The modern revival of necessity and possibility treated them as special cases of quantification [Vetter] |
19029 | It is necessary that p means that nothing has the potentiality for not-p [Vetter] |
19010 | All possibility is anchored in the potentiality of individual objects [Vetter] |
19013 | Possibility is a generalised abstraction from the potentiality of its bearer [Vetter] |
19028 | Possibilities are potentialities of actual things, but abstracted from their location [Vetter] |
23705 | A potentiality may not be a disposition, but dispositions are strong potentialities [Vetter, by Friend/Kimpton-Nye] |
19009 | Potentiality does the explaining in metaphysics; we don't explain it away or reduce it [Vetter] |
19019 | Potentiality is the common genus of dispositions, abilities, and similar properties [Vetter] |
19027 | Potentiality logic is modal system T. Stronger systems collapse iterations, and necessitate potentials [Vetter] |

4807 | A good barometer will predict a storm, but not explain it [Psillos] |
4811 | Induction (unlike deduction) is non-monotonic - it can be invalidated by new premises [Psillos] |
19018 | Explanations by disposition are more stable and reliable than those be external circumstances [Vetter] |
19020 | Grounding is a kind of explanation, suited to metaphysics [Vetter] |
4812 | Explanation is either showing predictability, or showing necessity, or showing causal relations [Psillos] |
4802 | Just citing a cause does not enable us to understand an event; we also need a relevant law [Psillos] |
4804 | The 'covering law model' says only laws can explain the occurrence of single events [Psillos] |
4805 | If laws explain the length of a flagpole's shadow, then the shadow also explains the length of the pole [Psillos] |
4806 | An explanation can just be a 'causal story', without laws, as when I knock over some ink [Psillos] |
4395 | There are non-causal explanations, most typically mathematical explanations [Psillos] |
4404 | Maybe explanation is entirely relative to the interests and presuppositions of the questioner [Psillos] |

2062 | The only movement possible for the One is in space or in alteration [Plato] |
233 | Some things do not partake of the One [Plato] |
4399 | Causes clearly make a difference, are recipes for events, explain effects, and are evidence [Psillos] |
4400 | Theories of causation are based either on regularity, or on intrinsic relations of properties [Psillos] |
4403 | We can't base our account of causation on explanation, because it is the wrong way round [Psillos] |
4789 | Three divisions of causal theories: generalist/singularist, intrinsic/extrinsic, reductive/non-reductive [Psillos] |
4790 | If causation is 'intrinsic' it depends entirely on the properties and relations of the cause and effect [Psillos] |
4402 | Empiricists tried to reduce causation to explanation, which they reduced to logic-plus-a-law [Psillos] |
4774 | Counterfactual claims about causation imply that it is more than just regular succession [Psillos] |
4793 | "All gold cubes are smaller than one cubic mile" is a true universal generalisation, but not a law [Psillos] |
4397 | Regularity doesn't seem sufficient for causation [Psillos] |
4401 | It is not a law of nature that all the coins in my pocket are euros, though it is a regularity [Psillos] |
4792 | A Humean view of causation says it is regularities, and causal facts supervene on non-causal facts [Psillos] |
4801 | The regularity of a cock's crow is used to predict dawn, even though it doesn't cause it [Psillos] |
4796 | Laws are sets of regularities within a simple and strong coherent system of wider regularities [Psillos] |
19039 | The view that laws are grounded in substance plus external necessity doesn't suit dispositionalism [Vetter] |
19038 | Dispositional essentialism allows laws to be different, but only if the supporting properties differ [Vetter] |
4799 | Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos] |
4780 | In some counterfactuals, the counterfactual event happens later than its consequent [Psillos] |
4791 | Counterfactual theories say causes make a difference - if c hadn't occurred, then e wouldn't occur [Psillos] |
