down from the past. The institutions—that is to say the habits of thought—under the guidance of which men live are in this way received from an earlier time; more or less remotely earlier, but in any event they have been elaborated in and received from the past. Institutions are products of the past process, are adapted to past circumstances, and are therefore never in full accord with the requirements of the present. In the nature of the case, this process of selective adaptation can never catch up with the progressively changing situation in which the community finds itself at any given time; for the environment, the situation, the exigencies of life which enforce the adaptation and exercise the selection, change from day to day; and each successive situation of the community in its turn tends to obsolescence as soon as it has been established. When a step in the development has been taken, this step itself constitutes a change of situation which requires a new adaptation; it becomes the point of departure for a new step in the adjustment, and so on interminably.
It is to be noted then, although it may be a tedious truism, that the institutions of today—the present accepted scheme of life—do not entirely fit the situation of today. At the same time, men's present habits of thought tend to persist indefinitely, except as circumstances enforce a change. These institutions which have thus been handed down, these habits of thought, points of view, mental attitudes and aptitudes, or what not, are therefore themselves a conservative factor. This is the factor of social inertia, psychological inertia, conservatism. Social structure changes, develops, adapts itself to an altered situation, only through a change in the habits of thought of the several classes of the community, or in the last analysis, through a change in the habits of thought of the individuals which make up the community. The evolution of society is substantially a process of mental adaptation on the part of individuals under the stress of circumstances which will no longer tolerate habits of thought formed under and conforming to a different set of circumstances in the past. For the immediate purpose it need not be a question of serious importance whether this adaptive process is a process of selection and survival of persistent ethnic types or a process of individual adaptation and an inheritance of acquired traits.
Social advance, especially as seen from the point of view of economic theory, consists in a continued progressive approach to an approximately exact "adjustment of inner relations to outer relations", but this adjustment is never definitively established, since the "outer relations" are subject to constant change as a consequence of the progressive change going on in the "inner relations." But the degree of approximation may be greater or less, depending on the facility with which an adjustment is made. A readjustment of men's habits of thought to conform with the exigencies of an altered situation is in any case made only tardily and reluctantly, and only under the coercion exercised by a stipulation which has made the accredited views untenable. The readjustment of institutions and habitual views to an altered environment is made in response to pressure from without; it is of the nature of a response to stimulus. Freedom and facility of readjustment, that is to say capacity for growth in social structure, therefore depends in great measure on the degree of freedom with which the situation at any given time acts on the individual members of the community-the degree of exposure of the individual members to the constraining forces of the environment. If any portion or class of society is sheltered from the action of the environment in any essential respect, that portion of the community, or that class, will adapt its views and its scheme of life more tardily to the altered general situation; it will in so far tend to retard the process of social transformation. The wealthy leisure class is in such a sheltered position with respect to the economic forces that make for change and readjustment. And it may be said that the forces which make for a readjustment of institutions, especially in the case of a modern industrial community, are, in the last analysis, almost entirely of an economic nature.
Any community may be viewed as an industrial or economic mechanism, the structure of which is made up of what is called its economic institutions. These institutions are habitual methods of carrying on the life process of the community in contact with the material environment in which it lives. When given methods of unfolding human activity in this given environment have been elaborated in this way, the life of the community will express itself with some facility in these habitual directions. The community will make use of the forces of the environment for the purposes of its life according to methods learned in the past and embodied in these institutions. But as population increases, and as men's knowledge and skill in directing the forces of nature widen, the habitual methods of relation between the members of the group, and the habitual method of carrying on the life process of the group as a whole, no longer give the same result as before; nor are the resulting conditions of life distributed and apportioned in the same manner or with the same effect among the various members as before. If the scheme according to which the life process of the group was carried on under the earlier conditions gave approximately the highest attainable result—under the circumstances—in the way of efficiency or facility of the life process of the group; then the same scheme of life unaltered will not yield the highest result attainable in this respect under the altered conditions. Under the altered conditions of population, skill, and knowledge, the facility of life as carried on according to the traditional scheme may not be lower than under the earlier conditions; but the chances are always that it is less than might be if the scheme were altered to suit the altered conditions.
The group is made up of individuals, and the group's life is the life of individuals carried on in at least ostensible severalty. The group's accepted scheme of life is the consensus of views held by the body of these individuals as to what is right, good, expedient, and beautiful in the way of human life. In the redistribution of the conditions of life that comes of the altered method of dealing with the environment, the outcome is not an equable change in the facility of life throughout the group. The altered conditions may increase the facility of life for the group as a whole, but the redistribution will usually result in a decrease of facility or fullness of life for some members of the group. An advance in technical methods, in population, or in industrial organization will require at least some of the members of the community to change their habits of life, if they are to enter with facility and effect into the altered industrial methods; and in doing so they will be unable to live up to the received notions as to what are the right and beautiful habits of life.
Any one who is required to change his habits of life and his habitual relations to his fellow men will feel the discrepancy between the method of life required of him by the newly arisen exigencies, and the traditional scheme of life to which he is accustomed. It is the individuals placed in this position who have the liveliest incentive to reconstruct the received scheme of life and are most readily persuaded to accept new standards; and it is through the need of the means of livelihood that men are placed in such a position. The pressure exerted by the environment upon the group, and making for a readjustment of the group's scheme of life, impinges upon the members of the group in the form of pecuniary exigencies; and it is owing to this fact—that external forces are in great part translated into the form of pecuniary or economic exigencies—it is owing to this fact that we can say that the forces which count toward a readjustment of institutions in any modern industrial community are chiefly economic forces; or more specifically, these forces take the form of pecuniary pressure. Such a readjustment as is here contemplated is substantially a change in men's views as to what is good and right, and the means through which a change is wrought in men's apprehension of what is good and right is in large part the pressure of pecuniary exigencies.
Any change in men's views as to what is good and right in human life make its way but tardily at the best. Especially is this true of any change in the direction of what is called progress; that is to say, in the direction of divergence from the archaic position—from the position which may be accounted the point of departure at any step in the social evolution of the community. Retrogression, reapproach to a standpoint to which the race has been long habituated in the past, is easier. This is especially true in case the development away from this past standpoint has not been due chiefly to a substitution of an ethnic type whose temperament is alien to the earlier standpoint. The cultural stage which lies immediately back of the present in the life history of Western civilization is what has here been called the quasi-peaceable stage. At this quasi-peaceable stage the law of status is the dominant feature in the scheme of
