Without discussing these chimerical schemes in detail, it will be well to expose the errors inherent in the method of reasoning which leads to them, because they are common to all the other progressive schools, the Positivist school excepted. The mistake consists in the first place, in disregarding or even denying the natural laws which regulate social phenomena; and secondly, in resorting to political agencies where moral agency is the real thing needed. The inadequacy and the danger of the various utopian systems which are now setting up their rival claims to bring about the regeneration of society, are all attributable in reality to these two closely-connected errors. For the sake of clearness, I shall continue to refer specially to Communism as the most prominent of these systems. But it will be easy to extend the bearing of my remarks to all the rest. [Individualization of functions as necessary as co-operation] The ignorance of the true laws of social life under which Communists labour is evident in their dangerous tendency to suppress individuality. Not only do they ignore the inherent preponderance in our nature of the personal instincts; but they forget that, in the collective Organism, the separation of functions is a feature no less essential than the co-operation of functions. Suppose for a moment that the connexion between men could be made such that they were physically inseparable, as has been actually the case with twins in certain cases of monstrosity; society would obviously be impossible. Extravagant as this supposition is, it may illustrate the fact that in social life individuality cannot be dispensed with. It is necessary in order to admit of that variety of simultaneous efforts which constitutes the immense superiority of the Social Organism over every individual life. The great problem for man is to harmonize, as far as possible, the freedom resulting from isolation, with the equally urgent necessity for convergence. To dwell exclusively upon the necessity of convergence would tend to undermine not merely our practical energy, but our true dignity; since it would do away with the sense of personal responsibility. In exceptional cases where life is spent in forced subjection to domestic authority, the comforts of home are often not enough to prevent existence from becoming an intolerable burden, simply from the want of sufficient independence. What would it be, then, if everybody stood in a similar position of dependence towards a community that was indifferent to his happiness? Yet no less a danger than this would be the result of adopting any of those utopian schemes which sacrifice true liberty to uncontrolled equality, or even to an exaggerated sense of fraternity. Wide as the divergence between Positivism and the Economic schools is, Positivists adopt substantially the strictures which they have passed upon Communism; especially those of Dunoyer, their most advanced writer.
