“The further we move beyond the direct definitional consequence…”

The less the conclusion follows automatically from the meaning of the original statement, the more reasoning is required to connect them.

Compare:

A.

Slavery was abolished and people legally classified as slaves ceased to be slaves.

Direct.

B.

Slavery was abolished and formerly enslaved people became legally free workers.

Some additional legal reasoning.

C.

Slavery was abolished and labor mobility increased.

Historical/economic reasoning required.

D.

Slavery was abolished and capitalist labor markets expanded.

More historical and economic reasoning.

E.

Slavery was abolished and industrial capitalism benefited.

Broader causal argument.

F.

Slavery was abolished primarily to benefit industrial capitalism.

Now we have a claim about motivation, requiring particularly strong evidence.
