|Causality: causality is the relation between two (separate) entities, whereby a state change of the one entity causes the state of the other entity to change. Nowadays it is assumed that an energy transfer is crucial for talking about a causal link.|
D. Hume was the first to consistently deny the observability of cause and effect. (David Hume Eine Untersuchung über den menschlichen Verstand, Hamburg, 1993, p. 95).

Causality/law/law of nature/Tractatus/Wittgenstein: 6:32 the law of causality is not a law but the form of a law - 6.321 law of causality is a generic name. E.g. as in mechanics.
6:36 if there were a law of causality, it might be: There are laws of nature - but that you cannot say, it turns out.
6.362 What can be described, can also happen, and what is excluded by the law of causality, cannot even be described.
