It must be emphasized here that all the material and economic progress of the modern world has not added greatly to the happiness or betterment of man. It is true that material progress is important, yes, necessary for spiritual progress. But material progress alone does not lead to spiritual progress, and therefore mere material progress can never add anything to the real happiness and social betterment of the race. On the contrary, it is possible to conceive of a society in which every one has an economic surplus,--a society rolling in wealth, approximately equally divided, and yet one in which human misery in its worst forms of vice and crime, pessimism and self-destruction, prevail. It is an old truth that making men "better-off" does not necessarily make them "better," and one which cannot be too often emphasized, but one which the modern socialist gets angry at when it is mentioned to him. It is therefore a matter of comparative indifference, from the standpoint of the happiness and ultimate survival of the race, whether economic goods are distributed relatively evenly in human society or not. We say comparative indifference, because, of course, no one can be indifferent to the material needs of life, inasmuch as they are the basis of its higher development. But after a certain minimum is assured it is extremely doubtful whether a surplus will be of benefit or not, and this minimum necessary for the higher spiritual development of the social life can be secured through the reform of present society without trying the doubtful social revolution which the socialists advocate. This brings us to a third criticism of Marxian socialism. Traditionally Marxian socialism has been revolutionary socialism. The vast mass of the socialist party to-day look forward to some revolution which will, as they say, "socialize the instruments of production," that is, transfer capital from private ownership and management to public ownership and management. Probably rightly, many socialists hold that such a wholesale transfer from private to public ownership would be the only way in which a socialistic regime could be successfully inaugurated. But if this revolution were accomplished it is evident that it is highly uncertain whether its results would be permanent. For all that we have learned concerning human society leads us to say that social organization at any particular time is very largely a matter of habit. Now collective habits are less easily changed than individual habits, because any change in collective habits practically necessitates the consent of all the individuals who make up the social group. We know also that even in individual life old habits are not easily supplanted by new ones and that there is always a tendency to revert to the old. All historical evidence shows that revolutions are always followed by periods of reaction, and that this reaction is usually proportionate to the extent and suddenness of change in social organization.
