And that all men may be restrained from invading others rights, and from doing hurt to one another, and the law of nature be observed, which willeth the peace and preservation of all mankind, the execution of the law of nature is, in that state, put into every man's hands, whereby every one has a right to punish the transgressors of that law to such a degree, as may hinder its violation: for the law of nature would, as all other laws that concern men in this world be in vain, if there were no body that in the state of nature had a power to execute that law, and thereby preserve the innocent and restrain offenders.
