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.
