Chapter LXIV: Section CCVI: Nature and Kinds of Consumption

As it is as little in the power of man to destroy matter as it is to create it, we mean by the consumption of goods, in the broad sense of the word, the abolition of or the doing away with an utility without any regard to the question whether another higher utility takes its place; in its narrower sense (consumption proper), a decrease of resources of any kind. Consumption is the counterpart of production (§ 30), the top of the tree of which production is the roots, and the circulation and distribution of goods the trunk. (_A. Walker._) There is, also, what Riedel calls immaterial consumption, as when a utility disappears, either because the want itself to which it ministers disappears or because views have changed as to the means to be employed towards its satisfaction.[206-1]

[Footnote 206-1: Diminutions of value, such, for instance,
as an almanac, a newspaper, etc., undergoes simply from the
appearance of the next years' etc.; of a shield or a part of
an officer's uniform with the initials of the reigning
sovereign, only because of the fact of a new succession to
the throne. A boot or a glove loses a great part of its
value when its mate is destroyed. (_Rau_, Lehrbuch, § 319.)]
