13869 | Number platonism says that natural number is a sortal concept [Wright,C] |
13870 | We can't use empiricism to dismiss numbers, if numbers are our main evidence against empiricism [Wright,C] |

19017 | Nomological dispositions (unlike ordinary ones) have to be continually realised [Vetter] |
19014 | How can spatiotemporal relations be understood in dispositional terms? [Vetter] |
9878 | Contextually defined abstract terms genuinely refer to objects [Wright,C, by Dummett] |
13868 | Sortal concepts cannot require that things don't survive their loss, because of phase sortals [Wright,C] |
19030 | Why does origin matter more than development; why are some features of origin more important? [Vetter] |

19029 | It is necessary that p means that nothing has the potentiality for not-p [Vetter] |
19028 | Possibilities are potentialities of actual things, but abstracted from their location [Vetter] |
19010 | All possibility is anchored in the potentiality of individual objects [Vetter] |
19013 | Possibility is a generalised abstraction from the potentiality of its bearer [Vetter] |

19022 | Water has a potentiality to acquire a potentiality to break (by freezing) [Vetter] |
23705 | A potentiality may not be a disposition, but dispositions are strong potentialities [Vetter, by Friend/Kimpton-Nye] |
19009 | Potentiality does the explaining in metaphysics; we don't explain it away or reduce it [Vetter] |

19020 | Grounding is a kind of explanation, suited to metaphysics [Vetter] |
13866 | A concept is only a sortal if it gives genuine identity [Wright,C] |
13865 | 'Sortal' concepts show kinds, use indefinite articles, and require grasping identities [Wright,C] |

13882 | A milder claim is that understanding requires some evidence of that understanding [Wright,C] |
13885 | If apparent reference can mislead, then so can apparent lack of reference [Wright,C] |
17857 | We can accept Frege's idea of object without assuming that predicates have a reference [Wright,C] |
15672 | Actions norms are only valid if everyone possibly affected is involved in the discourse [Habermas] |
19039 | The view that laws are grounded in substance plus external necessity doesn't suit dispositionalism [Vetter] |
19038 | Dispositional essentialism allows laws to be different, but only if the supporting properties differ [Vetter] |
