"Value denotes a relation reciprocally existing between two objects, and the precise relation which it denotes is the quantity of the one which can be obtained in exchange for a given quantity of the other"
About this Quote
Value does not reside inside a single object; it lives in the relationship between things. Nassau William Senior puts the emphasis on exchange, treating value as the concrete rate at which one good trades for another. Think of the world as a network of ratios: how many apples for one orange, how many yards of cloth for a bushel of wheat, how many hours of labor for a loaf of bread. Price is just a special case of this relationship when one of the objects is money. By calling the relation reciprocal, Senior highlights that it runs both ways: if one orange buys three apples, then one apple buys a third of an orange. Value is measurable only in these terms.
This perspective pushes back against any idea of intrinsic worth. An object can be beautiful or morally important, but economically its value is the quantity of other things it can command. That quantity shifts with preferences, technology, and scarcity. A new method that makes cloth plentiful will reduce the cloth-for-wheat ratio, even if nothing about wheat’s physical properties has changed. Value, then, is contextual and dynamic, not an essence that objects carry.
Senior wrote within classical political economy, after Adam Smith and David Ricardo, and before the full-blown marginal revolution. He criticized purely intrinsic accounts such as the labor theory of value and stressed that costs (including his famous notion of abstinence, or the sacrifice of waiting) and utility shape exchange ratios. In modern terms, his definition anticipates relative prices determined by supply and demand, where marginal willingness to trade and marginal costs meet.
Framing value as an exchange relation also clarifies money’s role. Money does not bestow absolute value; it simply serves as a convenient yardstick among many possible ones. When conditions change, the yardstick’s scale changes with them. Senior’s formulation is a disciplined way of saying that economics measures value by what you can get for what you give up, and it never stands alone from that trade.
