Some authorities hold that the Academy will be the most useful school, on the ground that its habit of disputing on both sides of a question approaches most nearly to the actual practice of the courts. And by way of proof they add the fact that this school has produced speakers highly renowned for their eloquence. The Peripatetics also make it their boast that they have a form of study which is near akin to oratory. For it was with them in the main that originated the practice of declaiming on general questions [*](See II. i. 9. III. v. 5. and 10.) by way of exercise. The Stoics, though driven to admit that, generally speaking, their teachers have been deficient both in fullness and charm of eloquence, still contend that no men can prove more acutely or draw conclusions with greater subtlety than themselves.
