In honor of the new anti-smoking law in Britain, a quotation from A Letter Concerning Toleration by John Locke (1689):
We have already proved that the care of souls does not belong to the magistrate. Not a magisterial care, I mean (if I may so call it), which consists in prescribing by laws and compelling by punishments. But a charitable care, which consists in teaching, admonishing, and persuading, cannot be denied unto any man. The care, therefore, of every man's soul belongs unto himself and is to be left unto himself. But what if he neglect the care of his soul? I answer: What if he neglect the care of his health or of his estate, which things are nearlier related to the government of the magistrate than the other? Will the magistrate provide by an express law that such a one shall not become poor or sick? Laws provide, as much as is possible, that the goods and health of subjects be not injured by the fraud and violence of others; they do not guard them from the negligence or ill-husbandry of the possessors themselves. No man can be forced to be rich or healthful whether he will or no. Nay, God Himself will not save men against their wills. Let us suppose, however, that some prince were desirous to force his subjects to accumulate riches, or to preserve the health and strength of their bodies. Shall it be provided by law that they must consult none but Roman physicians, and shall everyone be bound to live according to their prescriptions? What, shall no potion, no broth, be taken, but what is prepared either in the Vatican, suppose, or in a Geneva shop?

[A]m I beaten and ill-used by others because, perhaps, I wear not buskins; because my hair is not of the right cut; because, perhaps, I have not been dipped in the right fashion; because I eat flesh upon the road, or some other food which agrees with my stomach; because I avoid certain by-ways, which seem unto me to lead into briars or precipices; because, amongst the several paths that are in the same road, I choose that to walk in which seems to be the straightest and cleanest; because I avoid to keep company with some travellers that are less grave and others that are more sour than they ought to be?
