| 7797 | Axiom systems of logic contain axioms, inference rules, and definitions of proof and theorems [Girle] |

| 7788 | Modal logic has four basic modal negation equivalences [Girle] |
| 19664 | Paraconsistent logics are to prevent computers crashing when data conflicts [Meillassoux] |
| 19663 | We can allow contradictions in thought, but not inconsistency [Meillassoux] |
| 19665 | Paraconsistent logic is about statements, not about contradictions in reality [Meillassoux] |
| 7789 | Necessary implication is called 'strict implication'; if successful, it is called 'entailment' [Girle] |
| 21597 | Logical connectives have the highest precision, yet are infected by the vagueness of true and false [Russell, by Williamson] |
| 7790 | If an argument is invalid, a truth tree will indicate a counter-example [Girle] |
| 19677 | What is mathematically conceivable is absolutely possible [Meillassoux] |
| 19659 | The absolute is the impossibility of there being a necessary existent [Meillassoux] |

| 19668 | Hume's question is whether experimental science will still be valid tomorrow [Meillassoux] |
| 19650 | The transcendental subject is not an entity, but a set of conditions making science possible [Meillassoux] |
| 19667 | If the laws of nature are contingent, shouldn't we already have noticed it? [Meillassoux] |
| 19670 | Why are contingent laws of nature stable? [Meillassoux] |
