472 | No things would be clear to us as entity or relationships unless there existed Number and its essence [Philolaus] |
15884 | Laws of nature remain the same through any conditions, if the underlying mechanisms are unchanged [Harré] |
15880 | In physical sciences particular observations are ordered, but in biology only the classes are ordered [Harré] |

6120 | Causation depends on intrinsic properties [Mellor/Crane] |
15868 | Idealisation idealises all of a thing's properties, but abstraction leaves some of them out [Harré] |

15862 | Laws can come from data, from theory, from imagination and concepts, or from procedures [Harré] |
15870 | Are laws of nature about events, or types and universals, or dispositions, or all three? [Harré] |
15871 | Are laws about what has or might happen, or do they also cover all the possibilities? [Harré] |
15876 | Maybe laws of nature are just relations between properties? [Harré] |

15867 | Laws describe abstract idealisations, not the actual mess of nature [Harré] |
15872 | Must laws of nature be universal, or could they be local? [Harré] |
