2195 | We can discover some laws of nature, but never its ultimate principles and causes [Hume] |
14301 | We have no good concept of solidity or matter, because accounts of them are all circular [Hume] |
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] |
4579 | The idea of a final cause is very uncertain and unphilosophical [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] |
8382 | For Hume a constant conjunction is both necessary and sufficient for causation [Hume, by Crane] |
3662 | Hume says we can only know constant conjunctions, not that that's what causation IS [Hume, by Strawson,G] |

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] |
2234 | It is only when two species of thing are constantly conjoined that we can infer one from the other [Hume] |

19274 | Hume seems to presuppose necessary connections between mental events [Kripke on Hume] |
20705 | That events could be uncaused is absurd; I only say intuition and demonstration don't show this [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] |

6959 | We can't assume God's perfections are like our ideas or like human attributes [Hume] |
6957 | The objects of theological reasoning are too big for our minds [Hume] |
2244 | It can never be a logical contradiction to assert the non-existence of something thought to exist [Hume] |
21255 | No being's non-existence can imply a contradiction, so its existence cannot be proved a priori [Hume] |
21254 | A chain of events requires a cause for the whole as well as the parts, yet the chain is just a sum of parts [Hume] |
1435 | If something must be necessary so that something exists rather than nothing, why can't the universe be necessary? [Hume] |
6962 | The thing which contains order must be God, so see God where you see order [Hume] |
6958 | How can we pronounce on a whole after a brief look at a very small part? [Hume] |
21282 | Design cannot prove a unified Deity. Many men make a city, so why not many gods for a world? [Hume] |

21281 | This excellent world may be the result of a huge sequence of trial-and-error [Hume] |
21283 | Humans renew their species sexually. If there are many gods, would they not do the same? [Hume] |
6966 | Creation is more like vegetation than human art, so it won't come from reason [Hume] |
21284 | This Creator god might be an infant or incompetent or senile [Hume] |
21286 | Motion often begins in matter, with no sign of a controlling agent [Hume] |
21287 | The universe could settle into superficial order, without a designer [Hume] |
21288 | Ideas arise from objects, not vice versa; ideas only influence matter if they are linked [Hume] |
21256 | A surprise feature of all products of 9 looks like design, but is actually a necessity [Hume] |
6964 | From our limited view, we cannot tell if the universe is faulty [Hume] |
2232 | You can't infer the cause to be any greater than its effect [Hume] |
21279 | If the divine cause is proportional to its effects, the effects are finite, so the Deity cannot be infinite [Hume] |
6963 | Why would we infer an infinite creator from a finite creation? [Hume] |
6960 | Analogy suggests that God has a very great human mind [Hume] |
6965 | The universe may be the result of trial-and-error [Hume] |
6967 | Order may come from an irrational source as well as a rational one [Hume] |
2227 | A miracle violates laws which have been established by continuous unchanging experience, so should be ignored [Hume] |
7636 | It can't be more rational to believe in natural laws than miracles if the laws are not rational [Ishaq on 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] |
2185 | The idea of an infinite, intelligent, wise and good God arises from augmenting the best qualities of our own minds [Hume] |
21296 | If all of my perceptions were removed by death, nothing more is needed for total annihilation [Hume] |
