| 13051 | Deductive-nomological explanations will predict, and their predictions will explain [Salmon] |

| 17093 | Causation produces productive mechanisms; to understand the world, understand these mechanisms [Salmon] |
| 17492 | Salmon's interaction mechanisms needn't be regular, or involving any systems [Glennan on Salmon] |
| 13045 | Explanation at the quantum level will probably be by entirely new mechanisms [Salmon] |
| 13062 | Does an item have a function the first time it occurs? [Salmon] |

| 8412 | A causal interaction is when two processes intersect, and correlated modifications persist afterwards [Salmon] |
| 8413 | Cause must come first in propagations of causal interactions, but interactions are simultaneous [Salmon] |
