to understand each term in a
proposition and yet not be able to understand the meaning of the
proposition as a whole. When this is the case, we shall find it necessary
to make use of methods of exposition discussed later.

means, and then attempt to make an explanation that will show that you
thoroughly understand its meaning.)

+164. Exposition by Repetition.+--In discussing paragraph development
(Section 50) we have already learned that the meaning of a proposition may
be made clearer by the repetition of the topic statement. This repetition
may be used to supplement the definition of terms, or it may by itself
make clear both the meaning of the terms and of the proposition. Each
repetition of the proposition presents it to the reader in a new light or
in a stronger light. Each time the idea is presented it seems more
