These terms are often used as synonymous, but they signify entirely different things. "Wealth" consists of things in themselves valuable; "Money," of documentary claims to the possession of such things; and "Riches" is a relative term, expressing the magnitude of the possessions of one person or society as compared with those of other persons or societies.
The study of Wealth is a province of natural science:—it deals with the essential properties of things.
The study of Money is a province of commercial science:—it deals with conditions of engagement and exchange.
The study of Riches is a province of moral science:—it deals with the due relations of men to each other in regard of material possessions; and with the just laws of their association for purposes of labour.
I shall in this first chapter shortly sketch out the range of subjects which will come before us as we follow these three branches of inquiry.
12. And first of Wealth, which, it has been said, consists of things essentially valuable. We now, therefore, need a definition of "value."
"Value" signifies the strength, or "availing" of anything towards the sustaining of life, and is always twofold; that is to say, primarily, intrinsic, and secondarily, effectual.
The reader must, by anticipation, be warned against confusing value with cost, or with price. Value is the life-giving power of anything; cost, the quantity of labour required to produce it; price, the quantity of labour which its possessor will take in exchange for it.[11] Cost and price are commercial conditions, to be studied under the head of money.
13. Intrinsic value is the absolute power of anything to support life. A sheaf of wheat of given quality and weight has in it a measurable power of sustaining the substance of the body; a cubic foot of pure air, a fixed power of sustaining its warmth; and a cluster of flowers of given beauty a fixed power of enlivening or animating the senses and heart.
It does not in the least affect the intrinsic value of the wheat, the air, or the flowers, that men refuse or despise them. Used or not, their own power is in them, and that particular power is in nothing else.
