学以致用。智者用高尚的品味和博雅的学识武装自己——此乃经世致用的学问，而非市井杂谈。他们具备广博的智慧妙语，懂得大量的丰功伟绩，并且深知如何在各种情况下加以运用。通常情况下，用俏皮话的方式阐释严肃的教义更有益。灵活实用的知识比七艺(1)更有帮助，不管七艺有多么雅致。
a man of knowledge to the point. wise men arm themselves with tasteful and elegant erudition: a practical knowledge of what is going on not of a common kind but more like an expert. they possess a copious store of wise and witty sayings, and of noble deeds, and know how to employ them on fitting occasions. more is often taught by a jest than by the most serious teaching. pat knowledge helps some more than the seven arts, be they ever so liberal.
