4028 | Frege allows either too few properties (as extensions) or too many (as predicates) [Mellor/Oliver on Frege] |

4715 | We may say that objects have intrinsic identity conditions, but still allow multiple accounts of them [O'Grady] |
4719 | Maybe developments in logic and geometry have shown that the a priori may be relative [O'Grady] |

8488 | A concept is a function whose value is always a truth-value [Frege] |
9948 | Unlike objects, concepts are inherently incomplete [Frege, by George/Velleman] |
4710 | Verificationism was attacked by the deniers of the analytic-synthetic distinction, needed for 'facts' [O'Grady] |
8202 | Meaning is essence divorced from things and wedded to words [Quine] |

8201 | The distinction between meaning and further information is as vague as the essence/accident distinction [Quine] |
