"The training we're to do is not simply academic, although it certainly includes sound scholarship. We are also commanded to prepare each child to walk as a faithful Christian in all areas of life.
An arrow has two ends. On one end is the arrowhead. We want sharp arrows, academically speaking. But on the other end of the arrow, we find a delicate guidance system; fletching made of feathers, to be exact. We want our arrows to travel toward their target without deviation. This corresponds to the development of moral character.
A proper education will work on both ends of the arrow (i.e. both ends of the child) at the same time. Although scholarship is obviously important, a sharp arrow is worthless without proper direction. And a blunt arrow, even if it hits its target, will have very little effect."
