from the truth of one proposition.doc
Wittgenstein’s actual words are:
5.13 When the truth of one proposition follows from the truth of others, we can see this from the structure of the propositions.
5.133 All inference takes place a priori.
5.134 From an elementary proposition no other can be inferred.
5.135 In no way can an inference be made from the existence of another entirely different from it.
5.136 There is no causal nexus which justifies such an inference.
