Enjoin him to play so many hours every day, and look that he do it; and you shall see he will quickly be sick of it; and willing to leave it. By this… - John Locke

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 nobody that in the state of nature had a power to execute that law, and thereby preserve the innocent, and restrain offenders.

Truly, if the preservation of all mankind, as much as in him lies, were every one's persuasion, as indeed it is every one's duty, and the true principle to regulate our religion, politicks and morality by, the world would be much quieter, and better natur'd than it is.

Freedom then is not what Sir Robert Filmer tells us, O. A.8 55, “a liberty for every one to do what he lists, to live as he pleases, and not to be tied by any laws.” But freedom of men under government is to have a standing rule to live by, common to every one of that society, and made by the legislative power erected in it; a liberty to follow my own will in all things, where the rule prescribes not; and not to be subject to the inconstant, uncertain, unknown, arbitrary will of another man; as freedom of nature is to be under no other restraint but the law of nature.
