give it.

In a college or school argument you will usually follow it rather
closely; and you do well to do so, for you will thus fix in your mind a
useful model. But when you get out into the world, you will have to
consider in each case the needs and prepossessions of the particular
audience. Here as everywhere in the argument you must exercise judgment;
there is no formula which will fit all cases. The scheme of analysis of
the case which has been expounded in Chapter II has stood the test as
the best means yet found of exploring a subject and insuring clarity of
thought and certainty of attack;[57] but I know of no single fixed scheme
for the argument itself which will not be racked apart by the first half
dozen practical arguments you apply it to.

51. The Body of the Argument. In the main body of the argument the
difference from the brief will be largely a matter of expansion: the
brief indicates the evidence, the argument states it at length. Here
again you cut your argument to fit your audience and the space at your
command. In an argument in the editorial of a newspaper, which is rarely
longer than a long college theme, there is little space for the
statement of evidence. In Webster's argument in the White Murder Case,
which has some thirteen thousand words and which must have taken two
hours or more to deliver, the facts are studied in minute detail. Most
people are surprised to see the way in which a full statement of
evidence eats up space; if the facts are at all complicated, they must
be analyzed and expounded one by one and their bearing on the case laid
out in full. This necessity of using space in order to make facts clear
is the reason why it is so hard to find adequate and convincing
arguments which will print in less than fifteen or twenty pages. The
trouble with a swift and compact argument like that of Macaulay's on the
authorship of the _Junius Letters_ (see p. 155) is that unless you have
gone into the question for yourself, you do not know whether to accept
the stated facts or not. If you do accept them, the conclusion is
inevitable; but if you happen to know that scholars have long held the
decision doubtful, you want to know more about the facts in detail
before surrendering to Macaulay's conclusion. For an average reader
to-day, who knows little of the facts, this argument would have to be
greatly expanded.

In this expansion comes the chance for all the skill in exposition that
you can mus
