Let him be asked for an account not merely of the words of his lesson, but of its sense and substance, and let him judge the profit he has made by the testimony not of his memory, but of his life. Let him be made to show what he has just learned in a hundred aspects, and apply it to as many different subjects, to see if he has properly grasped it and made it his own, planning his progress according to the pedagogical method of Plato. It is a sign of rawness and indigestion to disgorge food just as we swallowed it. The stomach has not done its work if it has not changed the condition and form of what has been given it to cook.
