Further, seeing it is not enough to the Sustentation of a Common-wealth, that every man have a propriety in a portion of Land, or in some few commodities, or a naturall property in some usefull art, and there is no art in the world, but is necessary either for the being, or well being almost of every particular man; it is necessary, that men distribute that which they can spare, and transferre their propriety therein, mutually one to another, by exchange, and mutuall contract. And therefore it belongeth to the Common-wealth, (that is to say, to the Soveraign,) to appoint in what manner, all kinds of contract between Subjects, (as buying, selling, exchanging, borrowing, lending, letting, and taking to hire,) are to bee made; and by what words, and signes they shall be understood for valid. And for the Matter, and Distribution of the Nourishment, to the severall Members of the Common-wealth, thus much (considering the modell of the whole worke) is sufficient. Mony The Bloud Of A Common-wealth By Concoction, I understand the reducing of all commodities, which are not presently consumed, but reserved for Nourishment in time to come, to some thing of equal value, and withall so portably, as not to hinder the motion of men from place to place; to the end a man may have in what place soever, such Nourishment as the place affordeth. And this is nothing else but Gold, and Silver, and Mony. For Gold and Silver, being (as it happens) almost in all Countries of the world highly valued, is a commodious measure for the value of all things else between Nations; and Mony (of what matter soever coyned by the Soveraign of a Common-wealth,) is a sufficient measure of the value of all things else, between the Subjects of that Common-wealth. By the means of which measures, all commodities, Moveable, and Immoveable, are made to accompany a man, to all places of his resort, within and without the place of his ordinary residence; and the same passeth from Man to Man, within the Common-wealth; and goes round about, Nourishing (as it passeth) every part thereof; In so much as this Concoction, is as it were the Sanguification of the Common-wealth: For naturall Bloud is in like manner made of the fruits of the Earth; and circulating, nourisheth by the way, every Member of the Body of Man.
