The canon of reputability, then, must adapt itself to the economic circumstances, the traditions, and the degree of spiritual maturity of the particular class whose scheme of life it is to regulate. It is especially to be noted that however high its authority and however true to the fundamental requirements of reputability it may have been at its inception, a specific formal observance can under no circumstances maintain itself in force if with the lapse of time or on its transmission to a lower pecuniary class it is found to run counter to the ultimate ground of decency among civilized peoples, namely, serviceability for the purpose of an invidious comparison in pecuniary success.
It is evident that these canons of expenditure have much to say in determining the standard of living for any community and for any class. It is no less evident that the standard of living which prevails at any time or at any given social altitude will in its turn have much to say as to the forms which honorific expenditure will take, and as to the degree to which this "higher" need will dominate a people's consumption. In this respect the control exerted by the accepted standard of living is chiefly of a negative character; it acts almost solely to prevent recession from a scale of conspicuous expenditure that has once become habitual.
A standard of living is of the nature of habit. It is an habitual scale and method of responding to given stimuli. The difficulty in the way of receding from an accustomed standard is the difficulty of breaking a habit that has once been formed. The relative facility with which an advance in the standard is made means that the life process is a process of unfolding activity and that it will readily unfold in a new direction whenever and wherever the resistance to self-expression decreases. But when the habit of expression along such a given line of low resistance has once been formed, the discharge will seek the accustomed outlet even after a change has taken place in the environment whereby the external resistance has appreciably risen. That heightened facility of expression in a given direction which is called habit may offset a considerable increase in the resistance offered by external circumstances to the unfolding of life in the given direction. As between the various habits, or habitual modes and directions of expression, which go to make up an individual's standard of living, there is an appreciable difference in point of persistence under counteracting circumstances and in point of the degree of imperativeness with which the discharge seeks a given direction.
That is to say, in the language of current economic theory, while men are reluctant to retrench their expenditures in any direction, they are more reluctant to retrench in some directions than in others; so that while any accustomed consumption is reluctantly given up, there are certain lines of consumption which are given up with relatively extreme reluctance. 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 longer the habituation, the more unbroken the habit, and the more nearly it coincides with previous habitual forms of the life process, the more persistently will the given habit assert itself. The habit will be stronger if the particular traits of human nature which its action involves, or the particular aptitudes that find exercise in it, are traits or aptitudes that are already largely and profoundly concerned in the life process or that are intimately bound up with the life history of the particular racial stock.
The varying degrees of ease with which different habits are formed by different persons, as well as the varying degrees of reluctance with which different habits are given up, goes to say that the formation of specific habits is not a matter of length of habituation simply. Inherited aptitudes and traits of temperament count for quite as much as length of habituation in deciding what range of habits will come to dominate any individual's scheme of life. And the prevalent type of transmitted aptitudes, or in other words the type of temperament belonging to the dominant ethnic element in any community, will go far to decide what will be the scope and form of expression of the community's habitual life process. How greatly the transmitted idiosyncrasies of aptitude may count in the way of a rapid and definitive formation of habit in individuals is illustrated by the extreme facility with which an all-dominating habit of alcoholism is sometimes formed; or in the similar facility and the similarly inevitable formation of a habit of devout observances in the case of persons gifted with a special aptituDe in that direction. Much the same meaning attaches to that peculiar facility of habituation to a specific human environment that is called romantic love.
