It is not only true that it is the last liberties of man that are being taken away; and not merely his first or most superficial liberties. It is also inevitable that the last liberties should be taken first. It is inevitable that the most private matters should be most under public coercion. This inverse variation is very important, though very little realized. If a man’s personal health is a public concern, his most private acts are more public than his most public acts. The official must deal more directly with his cleaning his teeth in the morning than with his using his tongue in the market place. The inspector must interfere more with how he sleeps in the middle of the night than with how he works in the course of the day. The private citizen must have much less to say about his bath or his bedroom window than about his vote or his banking account. The policeman must be in a new sense a private detective; and shadow him in private affairs rather than in public affairs. A policeman must shut doors behind him for fear he should sneeze, or shove pillows under him for fear he should snore. All this and things far more fantastic follow from the simple formula that the State must make itself responsible for the health of the citizen. But the point is that the policeman must deal primarily and promptly with the citizen in his relation to his home, and only indirectly and more doubtfully with the citizen in his relation to his city. By the whole logic of this test, the king must hear what is said in the inner chamber and hardly notice what is proclaimed from the house-tops. We heard of a revolution that turns everything upside down. But this is almost literally a revolution that turns everything inside out.
