Whether there is any object, which, though it cannot measure the power of purchasing generally under the varying facilities of production and varying state of the demand and supply by which different commodities are affected, may be a correct measure of absolute and natural value as above described, is the specific object of the present inquiry. It follows directly, from the principles of Adam Smith, that the conditions of the supply of the great mass of commodities are, that the returns should be sufficient to pay the wages, profits and rents necessary to their production. If these payments be made in money at the ordinary rates of the time, they form what Adam Smith calls their natural prices. Money however we know is variable. But if for money we substitute the objects necessary to give the producer the same power of production and accumulation as the natural money prices would have commanded, such returns maybe considered as the natural conditions of the supply of commodities, and may with propriety be denominated their natural value, in contradistinction to their natural price. Of these three conditions of supply, or elements of natural value, the two first are obviously the most important. They are not only the sole conditions of supply in those early stages of society before the appropriation of land has taken place, but they continue to be so in reference to large classes of objects in the most advanced stages of improvement; and it is now generally acknowledged that even the main vegetable food of an improving country, which is the foundation of wages, must necessarily be of the same value as that part of the produce which is almost exclusively resolvable into wages and profits, and pays very little rent. We cannot therefore essentially err in assuming for the present that the natural value of objects in their more simple forms is composed of labour and profits,[A] and the effect of any portion of rent, or of other ingredients which are sometimes added to these elements, may be allowed for subsequently. We may also consider as a postulate which will be readily granted, that any given quantity of labour must be of the same value as the wages which command it, or for which it actually exchanges. Of the two main elements of value, labour and profits, the former, particularly if we include, as we ought to do, accumulated as well as immediate labour, is much the largest and most powerful.
