But there is another class whose attention also follows in the ways of least resistance; and life for them is a wallowing in the morbid and unwholesome. In them feeling is perverted, they seem to see life habitually through dark glasses; they passively attend to the sad, the distressing, sometimes the gruesome and the horrible with a sort of pallid joy in their own discolored images. The first group puts joy in all they see, because they are brimming full of joy themselves. These others find only the unwholesome in life because their minds are storehouses of it. We say that each type has projected himself, that is, has thrust himself out into the external world, and is standing back, looking at his own nature and calling that the universe. But neither of these two groups can long withstand the stress of a world they only feel and have never attempted to comprehend. The irresponsibly happy ones are too often crushed and broken when life proves to bring loss and failure and disappointment; the morbid probably will cease some day to enjoy their melancholic moods, and be unable to find their way out of them. If both had learned to control attention, they might have been saved. The happy, care-free child of the light is at desperate loss when the sun he loves is obscured, if he has not learned to look upon the far side of the clouds to find that there they glow golden with the rays temporarily shut from him. Because clouds were not interesting to him he never attended to them--and now he cannot. If the pessimistic, morbid one had looked away from the shadow to the sun it hid he, too, in the end might have seen with sane eyes and lived so wholesomely as to find all the good there was in life. Willed attention, rather than spineless feeling distractibility, might have saved him. When thinking can be forced to follow where trained reason directs, and can be kept in that direction, the greatest problem of physical and nervous well being is solved. To the nurse there is no other principle of psychology so important. But no child ever had his attention diverted by reasoning alone. The object at which you wish him to look must be made more impelling than the one he already sees, or he must want much to please you, else he only with his eyes will follow your command while his mind returns to his real interest; and the second you cease to command that eye service, he looks back to the thing that was holding him before. The beginning of all education is in arousing a _want to know_; in turning desire in the direction of knowledge.
