If there is some article of very generally recognised value which actually takes its place, as directly significant, on the scales of a great number of people, it may come to be generally accepted, without any special calculation or consideration, by people who are not thinking of any use they may have for it themselves, but are aware that it occupies a sufficiently high relative place on the scales of others to recoup them for what they give in exchange for it. As soon as this custom begins to be well established it will automatically extend and confirm itself, and the commodity in question will become a "currency" or "medium of exchange," the special characteristic of a medium of exchange being that it is accepted by a man who does not want it, or does not want it as much as what he gives for it, in order that he may exchange it for something he wants more.

He punished the evil tyrant and won the city of the Golden Kingdom of Malaya through his strength and skill, and with pious example transformed the profane mosque into a sacred temple. ...The time is coming, King Afonso VI, when holy Zion will have its freedom through you. And the Monarchy, consecrated by Heaven for eternity, that well-born plant which flowering will give fruit to Christendom, the theme of a thousand swans, singing about you as they immortalize themselves with you. Titus avenged the unjust death of Christ by the total destruction of Jerusalem; and God has chosen you to whom he gave an unconquerable heart to be the Avenger of His Faith. Take up the staff, then, when Heaven bids you march against the false worship of the Muslims, a worthy enterprise for your courage.
