But sympathetic imagination is not all a teacher needs. Exclusive altruism is absurd. On this point too I once got instruction from the mouths of babes and sucklings. The children of a friend of mine, children of six and four, had just gone to bed. Their mother overheard them talking when they should have been asleep. Wondering what they might need, she stepped into the entry and listened. They were discussing what they were here in the world for. That is about the size of problems commonly found in infant minds. The little girl suggested that we are probably in the world to help others. "Why, no indeed, Mabel," said her big brother, "for then what would others be here for?" Precisely! If anything is only fit to give away, it is not fit for that. We must know and prize its goodness in ourselves before generosity is even possible. Plainly, then, beside his aptitude for vicariousness, our ideal teacher will need the second qualification of an already accumulated wealth. These hungry pupils are drawing all their nourishment from us, and have we got it to give? They will be poor, if we are poor; rich if we are wealthy. We are their source of supply. Every time we cut ourselves off from nutrition, we enfeeble them. And how frequently devoted teachers make this mistake! dedicating themselves so to the immediate needs of those about them that they themselves grow thinner each year. We all know the "teacher's face." It is meagre, worn, sacrificial, anxious, powerless. That is exactly the opposite of what it should be. The teacher should be the big bounteous being of the community. Other people may get along tolerably by holding whatever small knowledge comes their way. A moderate stock will pretty well serve their private turn. But that is not our case. Supplying a multitude, we need wealth sufficient for a multitude. We should then be clutching at knowledge on every side. Nothing must escape us. It is a mistake to reject a bit of truth because it lies outside our province. Some day we shall need it. All knowledge is our province.
