  We first practice giving and receiving a verbal account on easy examples like weaving, which can also be observed and imaged. Then we practice on difficult examples, such as the statesman. Here we must give and receive a verbal account without relying on visual aids. But the statesman is still part of the exercise. Our inquiry about him is itself undertaken to make us better dialecticians, able to deal with all such topics. If we can succeed with the statesman, we will have learned a technique, or how to find a technique, that can be applied to other difficult cases, such as the philosopher.
