And so you may be polite to a child, and pretend to appreciate his point of view; but, unless you really do put yourself to the trouble of understanding him, unless you throw yourself, by the exercise of imagination, into his world, you will not succeed in being his friend. To be his friend means an effort on your part, it means that you must divest yourself of your own mental habit, and, for the time being, adopt his. And no nice phrases, no gifts of money, sweets or toys, can take the place of this effort, and this sacrifice of self. With five minutes of genuine surrender to him, you can win more of his esteem and gratitude than five hundred pounds would buy. His notion of real goodwill is the imaginative sharing of his feelings, a convinced participation in his pains and pleasures. He is well aware that, if you honestly do this, you will be on his side. * * * * * Now, adults, of course, are tremendously clever and accomplished persons and children are no match for them; but still, with all their talents and omniscience and power, adults seem to lack important pieces of knowledge which children possess; they seem to forget, and to fail to profit by, their infantile experience. Else why should adults in general be so extraordinarily ignorant of the great truth that the secret of goodwill lies in the sympathetic exercise of the imagination? Since goodwill is the secret of human happiness, it follows that the secret of goodwill must be one of the most precious aids to sensible living; and yet adults, though they once knew it, have gone and forgotten it! Children may well be excused for concluding that the ways of the adult, in their capricious irrationality, are past finding out.
