| 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] |

| 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] |
| 24030 | 3+4=7 is necessary because we cannot conceive of seven without including three and four [Descartes] |
| 15216 | Is conceptual necessity just conventional, or does it mirror something about nature? [Harré/Madden] |

| 6914 | Descartes transformed 'God is thinkable, so he exists' into 'I think, so I exist' [Descartes, by Feuerbach] |
| 4641 | In the Meditations version of the Cogito he says "I am; I exist", which avoids presenting it as an argument [Descartes, by Baggini /Fosl] |

| 15229 | We say there is 'no alternative' in all sorts of contexts, and there are many different grounds for it [Harré/Madden] |
| 20037 | Merely willing to walk leads to our walking [Descartes] |
| 5009 | We do not praise the acts of an efficient automaton, as their acts are necessary [Descartes] |
| 5008 | The greatest perfection of man is to act by free will, and thus merit praise or blame [Descartes] |

| 3635 | Essence must be known before we discuss existence [Descartes] |
| 8768 | Books are endless, and study is wearisome [Anon (Ecc)] |
| 19676 | Nature is devoid of thought [Descartes, by Meillassoux] |
| 15987 | Physics only needs geometry or abstract mathematics, which can explain and demonstrate everything [Descartes] |

| 16601 | Matter is not hard, heavy or coloured, but merely extended in space [Descartes] |
| 15292 | We can base the idea of a natural kind on the mechanisms that produce natural necessity [Harré/Madden] |

| 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] |

| 3637 | Ideas in God's mind only have value if he makes it so [Descartes] |
| 2287 | Existence and God's essence are inseparable, like a valley and a mountain, or a triangle and its properties [Descartes] |

| 3640 | Possible existence is a perfection in the idea of a triangle [Descartes] |
| 2274 | The idea of God in my mind is like the mark a craftsman puts on his work [Descartes] |
| 3639 | Necessary existence is a property which is uniquely part of God's essence [Descartes] |
| 2288 | I cannot think of a supremely perfect being without the supreme perfection of existence [Descartes] |

| 15295 | Theism is supposed to make the world more intelligible - and should offer results [Harré/Madden] |
| 16712 | Atheism is an atrocious and intolerable crime in any country [Descartes] |

| 3652 | I can't prove the soul is indestructible, only that it is separate from the mortal body [Descartes] |
| 3636 | God didn't give us good judgement even about our own lives [Gassendi on Descartes] |
| 2278 | Error arises because my faculty for judging truth is not infinite [Descartes] |
| 2277 | Since God does not wish to deceive me, my judgement won't make errors if I use it properly [Descartes] |
| 2281 | If we ask whether God's works are perfect, we must not take a narrow viewpoint, but look at the universe as a whole [Descartes] |
