5.454 In logic there is no coexistence, there can be no classification.

In logic there cannot be a more general or a more specific.

No classification? No generality? That can’t be what he means (surely?). Black (p. 268) says cf. 6.127: “all logical propositions are on the same level.”)

It depends on what entities one is trying to classify, I think. Black takes him to be talking about classifying logical propositions, in which case it's obvious why there's no classification: logical truths do not 'fall under' other logical truths.

Thanks.

Yes, I think Black must be right.
