12292 | Definitions are easily destroyed, since they can contain very many assertions [Aristotle] |
12283 | In definitions the first term to be assigned ought to be the genus [Aristotle] |
12272 | We describe the essence of a particular thing by means of its differentiae [Aristotle] |
12279 | The differentia indicate the qualities, but not the essence [Aristotle] |
12289 | The genera and the differentiae are part of the essence [Aristotle] |
12261 | Differentia are generic, and belong with genus [Aristotle] |
12263 | 'Genus' is part of the essence shared among several things [Aristotle] |

19144 | 'Epistemic' truth depends what rational creatures can verify [Davidson] |

19167 | Two sentences can be rephrased by equivalent substitutions to correspond to the same thing [Davidson] |
19166 | The Slingshot assumes substitutions give logical equivalence, and thus identical correspondence [Davidson] |
19150 | Coherence truth says a consistent set of sentences is true - which ties truth to belief [Davidson] |
19146 | Satisfaction is a sort of reference, so maybe we can define truth in terms of reference? [Davidson] |
19145 | We can explain truth in terms of satisfaction - but also explain satisfaction in terms of truth [Davidson] |
19174 | Axioms spell out sentence satisfaction. With no free variables, all sequences satisfy the truths [Davidson] |
19172 | To define a class of true sentences is to stipulate a possible language [Davidson] |
19136 | Many say that Tarski's definitions fail to connect truth to meaning [Davidson] |
19139 | Tarski does not tell us what his various truth predicates have in common [Davidson] |

19153 | Truth is basic and clear, so don't try to replace it with something simpler [Davidson] |

12280 | Genus gives the essence better than the differentiae do [Aristotle] |
13269 | In the case of a house the parts can exist without the whole, so parts are not the whole [Aristotle] |
12284 | Everything that is has one single essence [Aristotle] |

12290 | Destruction is dissolution of essence [Aristotle] |
12286 | If two things are the same, they must have the same source and origin [Aristotle] |
12266 | 'Same' is mainly for names or definitions, but also for propria, and for accidents [Aristotle] |

19152 | Utterances have the truth conditions intended by the speaker [Davidson] |
19162 | Meaning involves use, but a sentence has many uses, while meaning stays fixed [Davidson] |
19131 | We recognise sentences at once as linguistic units; we then figure out their parts [Davidson] |
19156 | Modern predicates have 'places', and are sentences with singular terms deleted from the places [Davidson] |

19133 | If you assign semantics to sentence parts, the sentence fails to compose a whole [Davidson] |
19132 | Top-down semantic analysis must begin with truth, as it is obvious, and explains linguistic usage [Davidson] |
19158 | 'Humanity belongs to Socrates' is about humanity, so it's a different proposition from 'Socrates is human' [Davidson] |
