17786 | The mainstream of modern logic sees it as a branch of mathematics [Mayberry] |
17788 | First-order logic only has its main theorems because it is so weak [Mayberry] |
17791 | Only second-order logic can capture mathematical structure up to isomorphism [Mayberry] |

17790 | No Löwenheim-Skolem logic can axiomatise real analysis [Mayberry] |
17778 | Axiomatiation relies on isomorphic structures being essentially the same [Mayberry] |

21838 | Before we seek solutions, it is important to invent problems [Deleuze] |
17784 | Real numbers can be eliminated, by axiom systems for complete ordered fields [Mayberry] |
17781 | Real numbers were invented, as objects, to simplify and generalise 'quantity' [Mayberry] |
17782 | Greek quantities were concrete, and ratio and proportion were their science [Mayberry] |
17799 | Cantor's infinite is an absolute, of all the sets or all the ordinal numbers [Mayberry] |
17797 | Cantor extended the finite (rather than 'taming the infinite') [Mayberry] |
17775 | If proof and definition are central, then mathematics needs and possesses foundations [Mayberry] |
17776 | The ultimate principles and concepts of mathematics are presumed, or grasped directly [Mayberry] |
17777 | Foundations need concepts, definition rules, premises, and proof rules [Mayberry] |
17804 | Axiom theories can't give foundations for mathematics - that's using axioms to explain axioms [Mayberry] |
17792 | 1st-order PA is only interesting because of results which use 2nd-order PA [Mayberry] |
17793 | It is only 2nd-order isomorphism which suggested first-order PA completeness [Mayberry] |
17794 | Set theory is not just first-order ZF, because that is inadequate for mathematics [Mayberry] |
17802 | We don't translate mathematics into set theory, because it comes embodied in that way [Mayberry] |
17805 | Set theory is not just another axiomatised part of mathematics [Mayberry] |
21908 | Ontology can be continual creation, not to know being, but to probe the unknowable [Deleuze] |
21902 | 'Being' is univocal, but its subject matter is actually 'difference' [Deleuze] |
21899 | There is no being beyond becoming [Deleuze] |
21903 | Ontology does not tell what there is; it is just a strange adventure [Deleuze, by May] |
21904 | Being is a problem to be engaged, not solved, and needs a new mode of thinking [Deleuze, by May] |
21847 | Before Being there is politics [Deleuze] |
21907 | We don't want another new set of categories; we want a variety of flexible categories [Deleuze, by May] |
17785 | Real numbers as abstracted objects are now treated as complete ordered fields [Mayberry] |
21840 | A meeting of man and animal can be deterritorialization (like a wasp with an orchid) [Deleuze] |
21843 | People consist of many undetermined lines, some rigid, some supple, some 'lines of flight' [Deleuze] |
