17374 | The possibility of prediction rests on determinism [Dupré] |

9575 | Husserl identifies a positive mental act of unification, and a negative mental act for differences [Husserl, by Frege] |

17378 | Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré] |

9819 | Psychologism blunders in focusing on concept-formation instead of delineating the concepts [Dummett on Husserl] |
9851 | Husserl wanted to keep a shadowy remnant of abstracted objects, to correlate them [Dummett on Husserl] |
22203 | Only facts follow from facts [Husserl] |
17381 | Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré] |
