in point of the degree of imperativeness with which the discharge seeks a given direction.

The articles or forms of consumption to which the consumer clings with the greatest tenacity are commonly the so-called necessaries of life, or the subsistence minimum. The subsistence minimum is of course not a rigidly determined allowance of goods, definite and invariable in kind and quantity; but for the purpose in hand it may be taken to comprise a certain, more or less definite, aggregate of consumption required for the maintenance of life. This minimum, it may be assumed, is ordinarily given up last in case of a progressive retrenchment of expenditure. That is to say, in a general way, the most ancient and ingrained of the habits which govern the individual's life—those habits that touch his existence as an organism—are the most persistent and imperative. Beyond these come the higher wants—later-formed habits of the individual or the race—in a somewhat irregular and by no means invariable gradation. Some of these higher wants, as for instance the habitual use of certain stimulants, or the need of salvation (in the eschatological sense), or of good repute, may in some cases take precedence of the lower or more elementary wants. In general, the
