Book 12
1.44
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.
