In the second case, there will not necessarily be either any diminished expenditure on luxuries and enjoyments, or any increased quantity of productive labour employed, but with the same labour more would be produced; wealth would increase, but not value. Of these two modes of increasing wealth, the last must be preferred, since it produces the same effect without the privation and diminution of enjoyments, which can never fail to accompany the first mode. Capital is that part of the wealth of a country which is employed with a view to future production, and may be increased in the same manner as wealth. An additional capital will be equally efficacious in the production of future wealth, whether it be obtained from improvements in skill and machinery, or from using more revenue reproductively; for wealth always depends on the quantity of commodities produced, without any regard to the facility with which the instruments employed in production may have been procured. A certain quantity of clothes and provisions will maintain and employ the same number of men, and will therefore procure the same quantity of work to be done, whether they be produced by the labour of 100 or of 200 men; but they will be of twice the value if 200 have been employed on their production. M. Say appears to me to have been singularly unfortunate in his definition of riches and value in the first chapter of his excellent work: the following is the substance of his reasoning: riches, he observes, consist only of things which have a value in themselves: riches are great, when the sum of 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_.
