Health and Liberty are without dispute the greatest natural Blessings Mankind is capable of enjoying; I say natural, because the contrary states are purely accidental, and arise from Nature debauched, depraved or enforced. Yet these Blessings are seldom sufficiently valued whilst enjoy’d; like the daily advantages of the Sun and Air, they seem scarce regarded because so common, by those that are in possession of them.

      But as an Italian that passes a Winter in Groenland, will soon be convinc’d through his want of the kind Influences of that glorious Planet, how much Misery he endures, in comparison of those who dwell in his Native Country, so he that knows by Experience the trouble of a languishing Sickness, or the loss of his Liberty, will presently begin to have a right esteem of that which formerly he scarce thought worth his notice.

      This Experience is either what a Man learns by that which befalls himself, or by making Observations on the condition of other People. The first is the common guide to the generality of Mankind, who are not apt to look beyond themselves, unless with St. Thomas they feel as well as see, they will not believe. Thus in the instance of bodily Health, we find those that have been always accustom’d to it, have scarce any Notion of the Misery of the contrary state, and therefore are careless in shunning those Excesses which might bring Diseases upon them; the sad Examples seen every day of miserable sick Debauchées, being not sufficient to deter others from lewdness. But the second sort of Experience is the Instructress of wise Men: For the Prudent will not fail to benefit themselves by the Accidents that befall others, both in their Health and Liberty, by avoiding the occasions of them: And this is one of the great Advantages of Society, that not only the Assistance, but even the Misfortunes of others, may be of use to us.

      Want of Liberty is a Disease in any Society or Body Politick, like want of Health in a particular Person; and as the best way to understand the nature of any Distemper aright, is to consider it in several Patients, since the same Disease may proceed from different causes, so the disorders in Society are best perceived by observing the Nature and Effects of them in our several Neighbours: Wherefore Travel seems as necessary to one who desires to be useful to his Country, as practising upon other Mens Distempers is to make an able Physician. For although a Man may see too frequently the Misery of such as are depriv’d of Health without quitting his own Country, yet (thanks to Providence) he must go out of these Kingdoms who would know experimentally the want of Publick Liberty. He that Travels into a Climate infected with this Disease (and he can find few that are not) does not only see, but in some measure feel the Grievances occasioned by it in the several Inconveniencies of living, in some proportion with the Natives; so as to relish better upon his return (which we suppose depends upon his choice) the freedom and ease of his own home Constitution; and may make good use of this Experience without having paid too dear for it. But a Man cannot transmigrate himself for a while into a distemper’d Body as he may Travel into an Enslaved Country, with equal facility of getting rid of each of them again.
