The secret of English mastery is self-mastery. The Englishman establishes a sort of satisfaction and equilibrium in his inner man, and from that citadel of rightness he easily measures the value of everything that comes within his moral horizon. In what may lie beyond he takes but a feeble interest. Enterprising enough when in a roving mood, and fond of collecting outlandish objects and ideas, he seldom allows his wanderings and discoveries to unhinge his home loyalties or ruffle his self-possession; and he remains, after all his adventures, intellectually as indolent and secure as in the beginning. As to speculative truth, he instinctively halts short of it, as it looms in the distance and threatens to cast a contemptuous and chilling shadow across his life. He would be very severe to any who dreaded cold water and wouldn't learn to swim; yet in the moral world he is himself subject to illusions of timidity. He does not believe, there, in the overwhelming rewards of courage. His chosen life is indeed beautiful--as the shy boy's might be--ill its finitude; all the more beautiful and worth preserving because, like his country, it is an island in the sea. His domestic thermometer and barometer have sufficed to guide him to the right hygiene.
Hygiene does not require telescopes nor microscopes. It is not concerned, like medicine or psychology, with the profound hidden workings of our bodies or minds, complexities hardly less foreign to our discoursing selves than are the mysteries of the great outer world. Hygiene regards only the right regimen of man in his obvious environment, judged by his conscious well-being. If it goes afield at all, it does so in the interests of privacy. All it asks of life is that it should be comely, spontaneous, and unimpeded: all it asks of the earth is that it should be fit for sport and for habitation. Men, to be of the right hygienic sort, must love the earth, and must know how to range in it. This the Englishman knows; and just as, in spite of his insularity, he loves this whole terraqueous globe simply and genuinely, so the earth, turned into mud by the vain stampings of so many garrulous and sickly nations, would doubtless say: Let the Englishman inhabit me, and I shall be green again.
