of political regulations on the subject, and the necessity of moral rules; for these and these only can ensure the right use of all our faculties without distinction. Intellectual effort, to be of any value, must be spontaneous; and it is doubtless an instinctive sense of this truth which prevents Communists from subjecting intellectual faculties to their utopian regulations. But Positivism can deal with these faculties which stand in the most urgent need of wise direction, without inconsistency and without disturbance. It leaves to them their fair measure of free action; and in the case of other faculties which, though less eminent, are hardly less dangerous to repress, it strengthens their freedom. When a pure morality arises capable of impressing a social tendency upon every phase of human activity, the freer our action becomes the more useful will it be to the public. The tendency of modern civilization, far from impeding private industry, is to entrust it more and more with functions, especially with those of a material kind, which were originally left to government. Unfortunately this tendency, which is very evident, leads economists into the mistake of supposing that industry may be left altogether without organization. All that it really proves is that the influence of moral principles is gradually preponderating over that of governmental regulations. [Action of organized public opinion upon Capitalists. Strikes] The method which is peculiar to Positivism of solving our great social problems by moral agencies, will be found applicable also to the settlement of industrial disputes, so far as the popular claims involved are well founded. These claims will thus become clear from all tendency to disorder, and will consequently gain immensely in force; especially when they are seen to be consistent with principles which are freely accepted by all, and when they are supported by a philosophic body of known impartiality and enlightenment. This spiritual power, while impressing on the people the duty of respecting their temporal leaders, will impose duties upon these latter, which they will find impossible to evade. As all classes will have received a common education, they will all alike be penetrated with the general principles on which these special obligations will rest. And these weapons, derived from no source but that of Feeling and Reason, and aided solely by Public Opinion, will wield an influence over practical life, of which nothing in the present day can give any conception. We might compare it with the influence of Catholicism in the Middle Ages, only that men are too apt to attribute the results of Catholicism to the chimerical hopes and fears which it inspired, rather than to the energy with which praise and blame were distributed. With the new spiritual power praise and blame will form the only resource; but it will be developed and consolidated to a degree which, as I have before shown, was impossible for Catholicism.
