Return to Physical Force
The use of physical force—even its retaliatory use—cannot be left at the discretion of individual citizens. Peaceful coexistence is impossible if a man has to live under the constant threat of force to be unleashed against him by any of his neighbors at any moment. Whether his neighbors’ intentions are good or bad, whether their judgment is rational or irrational, whether they are motivated by a sense of justice or by ignorance or by prejudice or by malice—the use of force against one man cannot be left to the arbitrary decision of another.
Visualize, for example, what would happen if a man missed his wallet, concluded that he had been robbed, broke into every house in the neighborhood to search it, and shot the first man who gave him a dirty look, taking the look to be a proof of guilt.
The retaliatory use of force requires objective rules of evidence to establish that a crime has been committed and to prove who committed it, as well as objective rules to define punishments and enforcement procedures. Men who attempt to prosecute crimes, without such rules, are a lynch mob. If a society left the retaliatory use of force in the hands of individual citizens, it would degenerate into mob rule, lynch law and an endless series of bloody private feuds or vendettas.
If physical force is to be barred from social relationships, men need an institution charged with the task of protecting their rights under an objective code of rules.
This is the task of a government—of a proper government—its basic task, its only moral justification and the reason why men do need a government.
A government is the means of placing the retaliatory use of physical force under objective control—i.e., under objectively defined laws.
