19542 | It is nonsense that understanding does not involve knowledge; to understand, you must know [Dougherty/Rysiew] |
19543 | To grasp understanding, we should be more explicit about what needs to be known [Dougherty/Rysiew] |
19541 | Rather than knowledge, our epistemic aim may be mere true belief, or else understanding and wisdom [Dougherty/Rysiew] |

8388 | Causation is either direct realism, Humean reduction, non-Humean reduction or theoretical realism [Tooley] |
8389 | Causation distinctions: reductionism/realism; Humean/non-Humean states; observable/non-observable [Tooley] |
8416 | Reductionists can't explain accidents, uninstantiated laws, probabilities, or the existence of any laws [Tooley] |
8393 | We can only reduce the direction of causation to the direction of time if we are realist about the latter [Tooley] |
8390 | Causation is directly observable in pressure on one's body, and in willed action [Tooley] |
8418 | Quantum physics suggests that the basic laws of nature are probabilistic [Tooley] |
8392 | Probabilist laws are compatible with effects always or never happening [Tooley] |
8399 | The actual cause may not be the most efficacious one [Tooley] |
8391 | In counterfactual worlds there are laws with no instances, so laws aren't supervenient on actuality [Tooley] |
8394 | Explaining causation in terms of laws can't explain the direction of causation [Tooley] |
8398 | Causation is a concept of a relation the same in all worlds, so it can't be a physical process [Tooley] |
