| 13580 | Causal powers must necessarily act the way they do [Ellis] |
| 13598 | Causal powers are often directional (e.g. centripetal, centrifugal, circulatory) [Ellis] |

| 13570 | Individual essences necessitate that individual; natural kind essences necessitate kind membership [Ellis] |
| 13607 | If events are unconnected, then induction cannot be solved [Ellis] |
| 18222 | Beneath every extrinsic explanation there is an intrinsic explanation [Field,H] |

| 13601 | Explanations of particular events are not essentialist, as they don't reveal essential structures [Ellis] |
| 13569 | To give essentialist explanations there have to be natural kinds [Ellis] |
| 13600 | The point of models in theories is not to idealise, but to focus on what is essential [Ellis] |

| 13574 | Natural kinds are distinguished by resting on essences [Ellis] |
| 13575 | If there are borderline cases between natural kinds, that makes them superficial [Ellis] |
| 13595 | Laws don't exist in the world; they are true of the world [Ellis] |
