Rh instrument, because it is a means to the attainment of corn. Corn is an instrument, being a means to the attainment of flour. Flour is an instrument, being a means to the attainment of bread. Bread is an instrument, as a means to the satisfaction of hunger and to the support of life. Here we at last arrive at things which are not instruments, being desired on their own account, and not as mere means to something beyond. This view of the subject is philosophically correct; or rather, this mode of expression may be usefully employed along with others, not as conveying a different view of the subject from the common one, but as giving more distinctness and reality to the common view. It departs, however, too widely from the custom of language, to be likely to obtain general acceptance, or to be of use for any other purpose than that of occasional illustration.

Wealth, then, may be defined, all useful or agreeable things which possess exchangeable value; or, in other words, all useful or agreeable things except those which can be obtained, in the quantity desired, without labour or sacrifice. To this definition, the only objection seems to be, that it leaves in uncertainty a question which has been much debated—whether what are called immaterial products are to be considered as wealth: whether, for example, the skill of a workman, or any other natural or acquired power of body or mind, shall be called wealth, or not: a question, not of very great importance, and which, so far as requiring discussion, will be more conveniently considered in another place.

These things having been premised respecting wealth, we shall next turn our attention to the extraordinary differences in respect to it, which exist between nation and nation, and between different ages of the world; differences both in the quantity of wealth, and in the kind of it; as well as in the manner in which the wealth existing in the community is shared among its members.
