The General Theory of the Good

Menger begins economics with the simplest possible relation: a person experiences a need, and something in the world is capable of satisfying it. A thing is not a good because it has a label, a price, or a place in trade. It becomes a good only when it stands in a causal relation to the satisfaction of a human need. Bread is a good to the hungry person because it can remove hunger. A medicine is a good to the sick person because it can restore health. The theory starts with want-satisfaction, not with exchange.

For a thing to have goods-character, four conditions must be present: a human need; properties in the thing that can satisfy the need; human knowledge of that causal connection; and command over the thing sufficient to direct it toward satisfaction. If one condition is missing, the thing is not an economic good for that person. Unknown medicine cannot function as medicine. A distant resource beyond reach cannot serve the actor. A useless object does not become a good merely because someone owns it.

Menger distinguishes goods that directly satisfy wants from goods that help produce those direct satisfactions. Bread is a first-order good because it can be consumed directly. Flour, ovens, milling equipment, wheat fields, and bakers' labour are higher-order goods because their goods-character depends on their causal connection to future bread. The higher the order, the farther the good stands from final consumption.

Higher-order goods often work only in combination. Wheat without milling, milling without an oven, and an oven without fuel may fail to produce bread. Menger therefore treats complementary goods as parts of a causal production chain. If a necessary complement is missing, the goods-character of the remaining higher-order items can weaken or disappear for the actor.

The first chapter can be read as a causal map: need gives economic relevance; knowledge connects the need to a serviceable thing; command makes the thing usable; and production links higher-order goods to lower-order goods. Menger's theory of goods is therefore a theory of meaningful relations, not a catalogue of objects.
