Compare for instance the methods of the present Commission on the Poor Law with those of the celebrated and extraordinarily able Commission which drew up the new Poor Law in 1833-34. The argument of the earlier Commissioners' Report runs on lines which it would be easy to put in a priori syllogistic form. All men seek pleasure and avoid pain. Society ought to secure that pain attaches to anti-social, and pleasure to social conduct. This may be done by making every man's livelihood and that of his children normally dependent upon his own exertions, by separating those destitute persons who cannot do work useful to the community from those who can, and by presenting these last with the alternative of voluntary effort or painful restriction. This leads to 'a principle which we find universally admitted, even by those whose practice is at variance with it, that the situation [of the pauper] on the whole shall not be made really or apparently so eligible as the situation of the independent labourer of the lowest class.'[[46]] The a priori argument is admirably illustrated by instances, reported by the sub-commissioners or given in evidence before the Commission, indicating that labouring men will not exert themselves unless they are offered the alternative of starvation or rigorous confinement, though no attempt is made to estimate the proportion of the working population of England whose character and conduct is represented by each instance.
This a priori deduction, illustrated, but not proved by particular instances, is throughout so clear and so easily apprehended by the ordinary man that the revolutionary Bill of 1834, which affected all sorts of vested interests, passed the House of Commons by a majority of four to one and the House of Lords by a majority of six to one.
The Poor Law Commission of 1905, on the other hand, though it contains many members trained in the traditions of 1834, is being driven, by the mere necessity of dealing with the mass of varied evidence before it, onto new lines. Instead of assuming half consciously that human energy is dependent solely on the working of the human will in the presence of the ideas of pleasure and pain, the Commissioners are forced to tabulate and consider innumerable quantitative observations relating to the very many factors affecting the will of paupers and possible paupers. They cannot, for instance, avoid the task of estimating the relative industrial effectiveness of health, which depends upon decent surroundings; of hope, which may be made possible by State provision for old age; and of the imaginative range which is the result of education; and of comparing all these with the 'purely economic' motive created by ideas of future pleasure and pain.
The evidence before the Commission is, that is to say, collected not to illustrate general propositions otherwise established, but to provide quantitative answers to quantitative questions; and instances are in each case accumulated according to a well-known statistical rule until the repetition of results shows that further accumulation would be useless.
In 1834 it was enough, in dealing with the political machinery of the Poor Law, to argue that, since all men desire their own interest, the ratepayers would elect guardians who would, up to the limit of their knowledge, advance the interests of the whole community; provided that electoral areas were created in which all sectional interests were represented, and that voting power were given to each ratepayer in proportion to his interest. It did not then seem to matter much whether the areas chosen were new or old, or whether the body elected had other duties or not.
In 1908, on the other hand, it is felt to be necessary to seek for all the causes which are likely to influence the mind of the ratepayer or candidate during an election, and to estimate by such evidence as is available their relative importance. It has to be considered, for instance, whether men vote best in areas where they keep up habits of political action in connection with parliamentary as well as municipal contests; and whether an election involving other points besides poor-law administration is more likely to create interest among the electorate. If more than one election, again, is held in a district in any year it may be found by the record of the percentage of votes that electoral enthusiasm diminishes for each additional contest along a very rapidly descending curve.
The final decisions that will be taken either by the Commission or by Parliament on questions of administrative policy and electoral machinery must therefore involve the balancing of all these and many other considerations by an essentially quantitative process. The line, that is to say, which ultimately cuts the curves indicated by the evidence will allow less weight either to anxiety for the future as a motive for exertion, or to personal health as increasing personal efficiency, than would be given to either if it were the sole factor to be considered. There will be more 'bureaucracy' than would be desirable if it were not for the need of economising the energies of the elected representatives, and less bureaucracy than there would be if it were not desirable to retain popular sympathy and consent. Throughout the argument the population of England will be looked upon not (as John Stuart Mill would have said) 'on the average or en masse,'[[47]] but as consisting of individuals who can be arranged in 'polygons of variation' according to their nervous and physical strength, their 'character' and the degree to which ideas of the future are likely to affect their present conduct.
Meanwhile the public which will discuss the Report has changed since 1834. Newspaper writers, in discussing the problem of destitution, tend now to use, not general terms applied to whole social classes like the 'poor,' 'the working class,' or 'the lower orders,' but terms expressing quantitative estimates of individual variations, like 'the submerged tenth,' or the 'unemployable'; while every newspaper reader is fairly familiar with the figures in the Board of Trade monthly returns which record seasonal and periodical variations of actual unemployment among Trade Unionists.
One could give many other instances of this beginning of a tendency in political thinking, to change from qualitative to quantitative forms of argument. But perhaps it will be sufficient to give one relating to international politics. 'Sixty years ago sovereignty was a simple question of quality. Austin had demonstrated that there must be a sovereign everywhere, and that sovereignty, whether in the hands of an autocracy or a republic, must be absolute. But the Congress which in 1885 sat at Berlin to prevent the partition of Africa from causing a series of European wars as long as those caused by the partition of America, was compelled by the complexity of the problems before it to approach the question of sovereignty on quantitative lines. Since 1885 therefore every one has become familiar with the terms then invented to express gradations of sovereignty: 'Effective occupation,' 'Hinterland,' 'Sphere of Influence'—to which the Algeçiras Conference has perhaps added a lowest grade, 'Sphere of Legitimate Aspiration.' It is already as unimportant to decide whether a given region is British territory or not, as it is to decide whether a bar containing a certain percentage of carbon should be called iron or steel.
Even in thinking of the smallest subdivisions of observed political fact some men escape the temptation to ignore individual differences. I remember that the man who has perhaps done more than any one else in England to make a statistical basis for industrial legislation possible, once told me that he had been spending the whole day in classifying under a few heads thousands of 'railway accidents,' every one of which differed in its circumstances from any other; and that he felt like the bewildered porter in Punch, who had to arrange the subleties of nature according to the unsubtle tariff-schedule of his company. 'Cats,' he quoted the porter as saying, 'is dogs, and guinea-pigs is dogs, but this 'ere tortoise is a hinsect.'
