ABSTRACT
For the intelligence of what follows it is important to distinguish
between structural relations of the kind shown in Chapters 1 and
7 and inferential relations, as already mentioned in Section 7.3.
Although structural relations can be to a certain extent considered
kinds of inferences (since they show how a statement can be derived
from other statements), the converse is not necessarily true, that is,
inferential relations do not always possess an insightful structural
meaning.
