10017 | Truth in a model is more tractable than the general notion of truth |

10018 | Truth is quite different in interpreted set theory and in the skeleton of its language |

10015 | Higher-order logic may be unintelligible, but it isn't set theory |

10011 | Identity is a level one relation with a second-order definition |

10016 | When an 'interpretation' creates a model based on truth, this doesn't include Fregean 'sense' |

10027 | Mathematics is higher-order modal logic |

10026 | Arithmetic must allow for the possibility of only a finite total of objects |

10022 | Numerical terms can't really stand for quantifiers, because that would make them first-level |

10021 | It is claimed that numbers are objects which essentially represent cardinality quantifiers |

10023 | Talk of mirror images is 'encoded fictions' about real facts |
