Such considerations are, perhaps, not altogether irrelevant at a time when facts have forced upon Englishmen the reconsideration of their social institutions which no appeal to theory could induce them to undertake. An appeal to principles is the condition of any considerable reconstruction of society, because social institutions are the visible expression of the scale of moral values which rules the minds of individuals, and it is impossible to alter institutions without altering that moral valuation. Parliament, industrial organizations, the whole complex machinery through which society expresses itself, is a mill which grinds only what is put into it, and when nothing is put into it grinds air. There are many, of course, who desire no alteration, and who, when it is attempted, will oppose it. They have found the existing economic order profitable in the past. They desire only such changes as will insure that it is equally profitable in the future. _Quand le Roi avait bu, la Pologne etait ivre_. They are genuinely unable to understand why their countrymen cannot bask happily by the fire which warms themselves, and ask, like the French farmer-general:--"When everything goes so happily, why trouble to change it?" Such persons are to be pitied, for they lack the social quality which is {4} proper to man. But they do not need argument; for Heaven has denied them one of the faculties required to apprehend it. There are others, however, who are conscious of the desire for a new social order, but who yet do not grasp the implications of their own desire. Men may genuinely sympathize with the demand for a radical change. They may be conscious of social evils and sincerely anxious to remove them. They may set up a new department, and appoint new officials, and invent a new name to express their resolution to effect something more drastic than reform, and less disturbing than revolution. But unless they will take the pains, not only to act, but to reflect, they end by effecting nothing. For they deliver themselves bound to those who think they are practical, because they take their philosophy so much for granted as to be unconscious of its implications, and directly they try to act, that philosophy re-asserts itself, and serves as an overruling force which presses their action more deeply into the old channels. "Unhappy man that I am; who shall deliver me from the body of this death?" When they desire to place their economic life on a better foundation, they repeat, like parrots, the word "Productivity," because that is the word that rises first in their minds; regardless of the fact that productivity is the foundation on which it is based already, that increased productivity is the one characteristic achievement of the age before the war, as religion was of the Middle Ages or art of classical Athens, and that it is precisely in the century which has seen the greatest increase in {5} productivity
