9556 | Nearly all of mathematics has to quantify over abstract objects [Quine] |
7707 | To grasp being, we must say why something exists, and why there is one world [Jacquette] |
7692 | Being is maximal consistency [Jacquette] |
7687 | Existence is completeness and consistency [Jacquette] |
7679 | Ontology is the same as the conceptual foundations of logic [Jacquette] |
7678 | Ontology must include the minimum requirements for our semantics [Jacquette] |

16462 | The quest for ultimate categories is the quest for a simple clear pattern of notation [Quine] |
7703 | If classes can't be eliminated, and they are property combinations, then properties (universals) can't be either [Jacquette] |
15723 | Either dispositions rest on structures, or we keep saying 'all things being equal' [Quine] |
15490 | Explain unmanifested dispositions as structural similarities to objects which have manifested them [Quine, by Martin,CB] |
8504 | Quine aims to deal with properties by the use of eternal open sentences, or classes [Quine, by Devitt] |
8464 | Physical objects in space-time are just events or processes, no matter how disconnected [Quine] |
7685 | An object is a predication subject, distinguished by a distinctive combination of properties [Jacquette] |
7924 | The notion of a physical object is by far the most useful one for science [Quine] |

17594 | We can paraphrase 'x=y' as a sequence of the form 'if Fx then Fy' [Quine] |
15725 | Normal conditionals have a truth-value gap when the antecedent is false. [Quine] |
15722 | Conditionals are pointless if the truth value of the antecedent is known [Quine] |
15719 | We feign belief in counterfactual antecedents, and assess how convincing the consequent is [Quine] |
15721 | Counterfactuals are plausible when dispositions are involved, as they imply structures [Quine] |

15720 | What stays the same in assessing a counterfactual antecedent depends on context [Quine] |
7691 | The actual world is a consistent combination of states, made of consistent property combinations [Jacquette] |
7688 | The actual world is a maximally consistent combination of actual states of affairs [Jacquette] |
7695 | Do proposition-structures not associated with the actual world deserve to be called worlds? [Jacquette] |
7694 | We must experience the 'actual' world, which is defined by maximally consistent propositions [Jacquette] |

4630 | Two theories can be internally consistent and match all the facts, yet be inconsistent with one another [Quine, by Baggini /Fosl] |
7706 | If qualia supervene on intentional states, then intentional states are explanatorily fundamental [Jacquette] |
7704 | Reduction of intentionality involving nonexistent objects is impossible, as reduction must be to what is actual [Jacquette] |
3131 | Quine expresses the instrumental version of eliminativism [Quine, by Rey] |
7702 | The extreme views on propositions are Frege's Platonism and Quine's extreme nominalism [Jacquette] |
3988 | Indeterminacy of translation also implies indeterminacy in interpreting people's mental states [Dennett on Quine] |
6311 | The firmer the links between sentences and stimuli, the less translations can diverge [Quine] |
6312 | We can never precisely pin down how to translate the native word 'Gavagai' [Quine] |
6313 | Stimulus synonymy of 'Gavagai' and 'Rabbit' does not even guarantee they are coextensive [Quine] |
6317 | Dispositions to speech behaviour, and actual speech, are never enough to fix any one translation [Quine] |

6314 | Weird translations are always possible, but they improve if we impose our own logic on them [Quine] |
