13986 | Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle] |
14150 | Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato] |
16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato] |

13602 | We cannot form an idea of a 'power', and the word is without meaning [Hume] |
227 | You must always mean the same thing when you utter the same name [Plato] |

228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato] |

218 | Participation is not by means of similarity, so we are looking for some other method of participation [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] |
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] |
217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |

2215 | There is no such thing as chance [Hume] |
2209 | Belief is stronger, clearer and steadier than imagination [Hume] |

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] |
2192 | All reasoning about facts is causal; nothing else goes beyond memory and senses [Hume] |
2184 | All ideas are copies of impressions [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] |

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] |
2199 | Reason cannot show why reliable past experience should extend to future times and remote places [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] |

2224 | Praise and blame can only be given if an action proceeds from a person's character and disposition [Hume] |

2062 | The only movement possible for the One is in space or in alteration [Plato] |
231 | Everything partakes of the One in some way [Plato] |
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] |
8341 | Hume never even suggests that there is no such thing as causation [Hume, by Strawson,G] |
8344 | At first Hume said qualities are the causal entities, but later he said events [Hume, by Davidson] |
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] |

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] |
234 | We couldn't discuss the non-existence of the One without knowledge of it [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] |
