There is a phenomenon which has from of old and in a peculiar degree attracted the attention of social philosophers and practical economists, the fact of certain commodities (these being in advanced civilizations coined pieces of gold and silver, together subsequently with documents representing those coins) becoming universally acceptable media of exchange. It is obvious even to the most ordinary intelligence, that a commodity should be given up by its owner in exchange for another more useful to him. But that (...) every economic unit in a nation should be ready to exchange his goods for little metal disks apparently useless as such, or for documents representing the latter, is a procedure so opposed to the ordinary course of things, that we cannot well wonder if even a distinguished thinker like Savigny finds it downright 'mysterious.' It must not be supposed that the form of coin, or document, employed as current money, constitutes the enigma in this phenomenon. We may look away from these forms and go back to earlier stages of economic development, or indeed to what still obtains in countries here and there, where we find the precious metals in a uncoined state serving as the medium of exchange, and even certain other commodities, cattle, skins, cubes of tea, slabs of salt, cowrie shells, etc.; still we are confronted by this phenomenon, still we have to explain why it is that the economic man is ready to accept a certain kind of commodity, even if he does not need it, or if his need of it is already supplied, in exchange for all the goods he has brought to market, while it is none the less what he needs that he consults in the first instance, with respect to the goods he intends to acquire in the course of his transactions. And hence there runs, from the first essays of reflective contemplation of a social phenomena down to our own times, an uninterrupted chain of disquisitions upon the nature and specific qualities of money in its relation to all that constitutes traffic..
