10861 | Beyond infinity cardinals and ordinals can come apart [Clegg] |
10860 | An ordinal number is defined by the set that comes before it [Clegg] |
10854 | Transcendental numbers can't be fitted to finite equations [Clegg] |

10853 | Either lack of zero made early mathematics geometrical, or the geometrical approach made zero meaningless [Clegg] |
10866 | Cantor's account of infinities has the shaky foundation of irrational numbers [Clegg] |

12774 | Without a substantial chain to link monads, they would just be coordinated dreams [Leibniz] |
12777 | Monads do not make a unity unless a substantial chain is added to them [Leibniz] |
