6264 | In Tarski's definition, you understand 'true' if you accept the notions of the object language [Putnam] |

9028 | Maybe logical truth reflects reality, but in different ways in different languages [Quine] |
10014 | Quine rejects second-order logic, saying that predicates refer to multiple objects [Quine, by Hodes] |

9015 | Universal quantification is widespread, but it is definable in terms of existential quantification [Quine] |
9025 | You can't base quantification on substituting names for variables, if the irrationals cannot all be named [Quine] |

9018 | A physical object is the four-dimensional material content of a portion of space-time [Quine] |

23065 | If only we could write like a reptile, of endless sensations and no concepts! [Cioran] |
6282 | Theory of meaning presupposes theory of understanding and reference [Putnam] |
6281 | Truth conditions can't explain understanding a sentence, because that in turn needs explanation [Putnam] |
6278 | We should reject the view that truth is prior to meaning [Putnam] |
9009 | Single words are strongly synonymous if their interchange preserves truth [Quine] |
6271 | How reference is specified is not what reference is [Putnam] |

6270 | The correct translation is the one that explains the speaker's behaviour [Putnam] |
6283 | Language maps the world in many ways (because it maps onto other languages in many ways) [Putnam] |
