From this our pupil will begin to proceed to more important themes, such as the praise of famous men and the denunciation of the wicked. Such tasks are profitable in more than one respect. The mind is exercised by the variety and multiplicity of the subject matter, while the character is moulded by the contemplation of virtue and vice. Further wide knowledge of facts is thus acquired, from which examples may be drawn if circumstances so demand, such illustrations being of the utmost value in every kind of case.
It is but a step from this to practice in the comparison of the respective merits of two characters. This is of course a very similar theme to the preceding, but involves a duplication of the subject matter and deals not merely with the nature of virtues and vices, but with their degree as well. But the method to be followed in panegyric and invective will be dealt with in its proper place, as it forms the third department of rhetoric. [*](Book III. chap. vii.)
As to commonplaces (I refer to those in which we denounce vices themselves such as adultery, gambling or profligacy without attacking particular persons), they come straight from the courts and, if we add the name of the defendant, amount to actual accusations. As a rule, however, the general character of a commonplace is usually given a special turn: for instance we make our adulterer blind, our gambler poor and our profligate far advanced in years. Sometimes too they entail
for we may speak on behalf of luxury or love, while a pimp or a parasite may be defended in such a way that we appeal as counsel not for the character itself, but to rebut some specific charge that is brought against him.
Theses on the other hand are concerned with the comparison of things and involve questions such as
Which is preferable, town or country life?or
Which deserves the greatest praise, the lawyer or the soldier?These provide the most attractive and copious practice in the art of speaking, and are most useful whether we have an eye to the duties of deliberative oratory or the arguments of the courts. For instance Cicero in his pro Murena [*](Pro Mur. ix. 21 sqq. ) deals very fully with the second of the two problems mentioned above.
