Note 28 — Chapter XVIII

"The first man who knew how to soften metals by fire, is not the creator of the value which that process adds to the melted metal. That value is the result of the physical action of fire added to the industry and capital of those who availed themselves of this knowledge."

"From this error Smith has drawn this false result, that the value of all productions represents the recent or former labour of man, or in other words, that riches are nothing else but accumulated labour; from which, by a second consequence, equally false, labour is the sole measure of riches, or of the value of productions."29 The inferences with which M. Say concludes are his own, and not Dr. Smith's; they are correct if no distinction be made between value and riches: but though Adam Smith, who defined riches to consist in the abundance of necessaries, conveniences, and enjoyments of human life, would have allowed that machines and natural agents might very greatly add to the riches of a country, he would not have allowed that they add any thing to value in exchange.
