Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune.
The good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.

I once heard a learned man say, "Every evil has its remedy, except folly. To reprimand an obstinate fool or to preach to a dolt is like writing upon the water. Christ healed the blind, the halt, the palsied, and the leprous. But the fool He could not cure."

They help him to use the world for purposes of his own devising rather than understand and explain it.
