The use of our concept in this connection is firmly bound to its use in the preceding classes. For it is no accident that in the mechanistic process called evolution human aims and purposes have come to be furthered and achieved principally through the power and skill of the arm and hand. The “right” arm and hand point reasonably _straight_, throw missiles in a fairly direct _manner_, and their powerful shots bring down the quarry _immediately_. (Class A.) These parts of the body are also among the most educible and skilful in the technique requisite for bringing about a desired end. Their action-patterns are indeed often the very method by which ambitions are achieved. (Class B.) And when we have reached a judgment that is deemed to be true or in accordance with the facts of the matter (Class C.), it is our “right” hand that is ready to be motivated in its defence. Even the art of writing, in the original sense of cutting, tearing, or scratching to produce a record or a design, is not at all distantly related to the functions of this part of the body. With this clearly understood, the transition is easy to make to CLASS E _Legal “Rights”; that is, Those Claims and Interests the Establishment and Protection of Which May Be Secured by Force and even Violence._[14] As used in this connection, “right” is partially equivalent to _might_, since our concept here connotes an organized force,—a physical power,—which, under given conditions, can be employed for the purpose of establishing claims and protecting interests. This organized force is popularly referred to as “the Law,” especially by those who indulge in back-yard altercations and cry out: “If you do that again, I’ll have the Law on you!” And the ordinary man, whose six or seven years of public schooling have implanted in him the fixed habit of reifying all abstractions, understands the law as equivalent to a transcendental force of some kind which makes his threats effective. As befits the mental calibre of such a man, the law frequently becomes synonymous with the functions of the police, who are naïvely supposed to know when and how to protect everybody’s legal rights. This is an error. Not only are the police extremely ignorant persons, but they have scarcely any legal status whatever. They are “the tolerated remnant of the autocratic power which absolute monarchs once exercised over their subjects.” Law and legal rights are functions of the courts, while the police are simply unattached huskies hired to bring into court those who do not come there of their own initiative. We must look elsewhere for the source of the might which legal rights are said and felt to possess, namely, in the origin and function of law itself.
