Again, more than ninety-five children out of every hundred leave school before they are sufficiently mature to comprehend those studies which open their eyes to the universe, which bear upon their relations to their fellow-men, upon their duties as citizens of a state, as members of organized society. These are the studies that deal with the most important problems that mankind has to solve. They cannot be taught to children; they cannot be taught--dogmatically--at all. They involve the consideration of burning questions, subjects of bitter controversy--the world-old battle between conservatism and innovation which, as Emerson says, "is the subject of civil history." They cannot be taught by any teacher, they cannot be taught by any text-book or by any one book. Their adequate consideration calls for the reading of many books--books of the present and the future as well as the past. The electrician who allows himself to be guided by the treatises of twenty years ago would have no standing; neither has the economist or sociologist who has not kept up with the literature of the last thirty years--or the last three years. It would be of no particular advantage for all of us to be electricians. We can safely trust that field to experts; but it is extremely desirable that every man should comprehend the great issues of economics and politics. The school cannot even PRESENT the important problems of sociology; the university cannot adequately do so without the library. On no other subject is the wide reading that Matthew Arnold enjoins so necessary. And no other subject is of such momentous importance to mankind; for the betterment of social conditions is a necessary forerunner and foundation of moral and religious progress. And that cannot be true religion which does not lead to social betterment. In that noblest aspiration ever put into the mouth and mind and heart (too often, alas, only the mouth!) of man we are taught to pray not that we may be transplanted to a better world, but that God's kingdom may come and His will be done in this world.
