Proverbs 15:2

The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

Wisdom is known by using knowledge well, rightly and aright. It is not mere possession of facts but the right handling of what is known.

True education imparts that wisdom by teaching the best and right use of knowledge, learning, powers, and all abilities. It trains for right service and duty to oneself, to the world, and to God.
