"We cannot, if we would, play the part of China, and be content to rot by inches in ignoble ease within our borders, taking no interest in what goes on beyond them, sunk in a scrambling commercialism; heedless of the higher life, the life of aspiration, of toil and risk, busying ourselves only with the wants of our bodies for the day, until suddenly we should find, beyond a shadow of question, what China has already found, that in this world the nation that has trained itself to a career of unwarlike and isolated ease is bound, in the end, to go down before other nations which have not lost the manly and adventurous qualities.
