If every person has the right to defend--even by force--his person, his liberty, and his property, then it follows that a group of men have the right to organize and support a common force to protect these rights constantly. Thus the principle of collective right — its reason for existing, its lawfulness — is based on individual right. And the common force that protects this collective right cannot logically have any other purpose or any other mission than that for which it acts as a substitute. Thus, since an individual cannot lawfully use force against the person, liberty, or property of another individual, then the common force — for the same reason — cannot lawfully be used to destroy the person, liberty, or property of individuals or groups.
