CHAPTER XVIII.

the values of which they are composed is great. They are small when the sum of their values is small. Two things having an equal value, are riches of equal amount. They are of equal value, when by general consent they are freely exchanged for each other. Now, if mankind attach value to a thing, it is on account of the uses to which it is applicable. This faculty, which certain things have, of satisfying the various wants of mankind, I call utility. To create objects that have a value of any kind is to create riches, since the utility of things is the first foundation of their value, and it is the value of things which constitutes riches. But we do not create objects: all we can do is to reproduce matter under another form—we can give it utility. Production then is a creation, not of matter but of utility, and it is measured by the value arising from the utility of the object produced. The utility of any object, according to general estimation, is pointed out by the quantity of other commodities for which it will exchange. This valuation, arising from the general estimate formed by society, constitutes what Adam Smith calls value in exchange; what Turgot calls appreciable value; and what we may more briefly designate by the term value.
