15344 | Deflationism skips definitions and models, and offers just accounts of basic laws of truth [Horsten] |

15353 | The first incompleteness theorem means that consistency does not entail soundness [Horsten] |
15355 | Strengthened Liar: 'this sentence is not true in any context' - in no context can this be evaluated [Horsten] |
