A failure to see this distinction and to keep it clearly in mind has led to confusion, even on the part of legislatures, learned judges, and able economists.
If property is said to be (for example) a house and lot and at the same time the right to that house and lot, then there are two properties at once for each economic good, viz.: the object itself and the right to it.[3] This difficulty could be avoided by the consistent definition and use of terms.

A material economic object is a good, is a form of wealth.
The usance of wealth and the service of laborers at the moment rendered constitute forms of income.

The right of ownership, i.e., the right to control, use, or direct the use of wealth and services, is property, which is therefore the right to receive incomes.

The value of the incomes of an individual constitute his capital.

Goods, rights to goods, value of rights to goods: these three things are clearly distinguishable.
