Imagine for example that a skilful commander, without whose aid the state cannot hope to crush its enemies, is labouring under a charge which is obviously true: will not the common interest irresistibly summon our orator to defend him? We know at any rate that Fabricius publicly voted for and secured the election to the consulate of Cornelius Rufinus,
I might produce many other similar examples, but one of them taken at random is enough. For my purpose is not to assert that such tasks will often be incumbent on the orator whom I desire to form, but merely to show that, in the event of his being compelled to take such action, it will not invalidate our definition of an orator as a
good man, skilled in speaking.
And it is necessary also both to teach and learn how to establish difficult cases by proof. For often even the best cases have a resemblance to bad and, the charges which tell heavily against an innocent person frequently have a strong resemblance to the truth. Consequently, the same methods of defence have to be employed that would be used if he were guilty. Further, there are countless elements which are common to both good cases and bad, such as oral and documentary evidence, suspicions and opinions, all of which have to be established or disposed of in the same way, whether they be true or merely resemble the truth. Therefore, while maintaining his integrity of purpose, the orator will modify his pleading to suit the circumstances.
Since then the orator is a good man, and such goodness cannot be conceived as existing apart from
unless indeed we agree with those who regard morality as intuitive and as owing nothing to instruction: indeed they go so far as to acknowledge that handicrafts, not excluding even those which are most despised among them, can only be acquired by the result of teaching, whereas virtue, which of all gifts to man is that which makes him most near akin to the immortal gods, comes to him without search or effort, as a natural concomitant of birth. But can the man who does not know what abstinence is, claim to be truly abstinent?
or brave, if he has never purged his soul of the fears of pain, death and superstition? or just, it he has never, in language approaching that of philosophy, discussed the nature of virtue and justice, or of the laws that have been given to mankind by nature or established among individual peoples and nations? What a contempt it argues for such themes to regard them as being so easy of comprehension!
