The time is past when any one seriously believes that political freedom or personal liberty will be universal, just because everybody has a right to talk, to move from place to place, to print stories in the newspapers. The relation of man to man to-day requires that we formulate rules of action that prevent one man's taking from another those rights, economic and industrial, that are as essential to twentieth-century happiness as were political rights to eighteenth-century happiness. Political maxims showed how, through common desire and common action, steps could be taken by the individual and by the whole of society for the protection of all. Health rights, likewise, are to be obtained through common action. A modern city must know who is accountable when an automobile runs over a pedestrian, when a train load of passengers lose their lives because of an engineer's carelessness, when an employee is incapacitated for work by an accident for which he is not responsible, or when fever epidemics threaten life and liberty without check. How can a child who is prevented by removable physical defects from breathing through his nose be enthusiastic over free speech? Of what use is freedom of the press to those who find reading harder than factory toil? How futile the right to trial by jury if removable physical defects make children unable to do what the law expects! Who would not exchange rights of petition for ability to earn a living? Children permanently incapacitated to share the law's benefits cannot appreciate the privilege of pursuing happiness.
Succeeding chapters will enumerate a number of health rights and will show through what means we can work together to guarantee that we shall not injure the health of our neighbor and that our neighbor shall not injure our health. The truest index to economic status and to standards of living is health environment. The best criterion of opportunity for industrial and political efficiency is the conditions affecting health. The seven catchwords that describe seven motives to health legislation and health administration, seven ways of approaching health needs, and seven reasons for meeting them, should be found helpful in analyzing the problem confronting the individual leader. Generally speaking, we cannot watch political rights grow, but health rights are evolved before our eyes all the time. If we wish, we can see in our own city or township the steps taken, one by one, that have slowly led to granting a large number of health rights to every American.
