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. Men differ in respect of transmitted aptitudes, or in respect of the relative facility with which they unfold their life activity in particular directions; and the habits which coincide with or proceed upon a relatively strong specific aptitude or a relatively great specific facility of expression become of great consequence to the man's well-being. The part played by this element of aptitude in determining the relative tenacity of the several habits which constitute the standard of living goes to explain the extreme reluctance with which men give up any habitual expenditure in the way of conspicuous consumption. The aptitudes or propensities to which a habit of this kind is to be referred as its ground are those aptitudes whose exercise is comprised in emulation; and the propensity for emulation--for invidious comparison--is of ancient growth and is a pervading trait of human nature. It is easily called into vigorous activity in any new form, and it asserts itself with great insistence under any form under which it has once found habitual expression. When the individual has once formed the habit of seeking expression in a given line of honorific expenditure--when a given set of stimuli have come to be habitually responded to in activity of a given kind and direction under the guidance of these alert and deep-reaching propensities of emulation--it is with extreme reluctance that such an habitual expenditure is given up. And on the other hand, whenever an accession of pecuniary strength puts the individual in a position to unfold his life process in larger scope and with additional reach, the ancient propensities of the race will assert themselves in determining the direction which the new unfolding of life is to take. And those propensities which are already actively in the field under some related form of expression, which are aided by the pointed suggestions afforded by a current accredited scheme of life, and for the exercise of which the material means and opportunities are readily available--these will especially have much to say in shaping the form and direction in which the new accession to the individual's aggregate force will assert itself. That is to say, in concrete terms, in any community where conspicuous consumption is an element of the scheme of life, an increase in an individual's ability to pay is likely to take the form of an expenditure for some accredited line of conspicuous consumption.
