There are also
three aims which the orator must always have in
view; he must instruct, move and charm his hearers.
This is a clearer division than that made by those
who divide the task of oratory into that which relates
to things and that which concerns the emotions,
since both of these will not always be present in the
subjects which we shall have to treat. For some
themes are far from calling for any appeal to the
emotions, which, although room cannot always be
found for them, produce a most powerful effect
wherever they do succeed in forcing their way.
