| 17288 | We learn grounding from what is grounded, not what does the grounding [Fine,K] |
| 17281 | If grounding is a relation it must be between entities of the same type, preferably between facts [Fine,K] |
| 17280 | Ground is best understood as a sentence operator, rather than a relation between predicates [Fine,K] |

| 17289 | Every necessary truth is grounded in the nature of something [Fine,K] |
| 17291 | We explain by identity (what it is), or by truth (how things are) [Fine,K] |

| 17277 | If mind supervenes on the physical, it may also explain the physical (and not vice versa) [Fine,K] |
| 9919 | The old debate classified representations as abstract, not entities [Burgess/Rosen] |
| 1554 | Contradiction is impossible, since only one side of the argument refers to the true facts [Prodicus, by Didymus the Blind] |
