The division is as old as Aristotle. “Of everything which we possess there are two uses both belonging to the thing as such, but not in the same manner; for one is the proper and the other the improper or secondary use of it. For example, the shoe is used for wear, and it is used for exchange; both are uses of the shoe.”—Politics (Jowett), § 9.
