The economic and social order of the modern world exhibits a strange enigma, which only a prosperous thoughtlessness can regard with indifference or, indeed, without a shudder. We have made such splendid advances in art and science that the unlimited forces of nature have been brought into subjection, and only await our command to perform for us all our disagreeable and onerous tasks, and to wring from the soil and prepare for use whatever man, the master of the world, may need. As a consequence, a moderate amount of labour ought to produce inexhaustible abundance for everyone born of woman; and yet all these glorious achievements have not--as Stuart Mill forcibly says--been able to mitigate one human woe. And, what is more, the ever-increasing facility of producing an abundance has proved a curse to multitudes who lack necessaries because there exists no demand for the many good and useful things which they are able to produce. The industrial activity of the present day is a ceaseless confused struggle with the various symptoms of the dreadful evil known as 'over-production.' Protective duties, cartels and trusts, guild agitations, strikes--all these are but the desperate resistance offered by the classes engaged in production to the inexorable consequences of the apparently so absurd, but none the less real, phenomenon that increasing facility in the production of wealth brings ruin and misery in its train. That science stands helpless and perplexed before this enigma, that no beam of light has yet penetrated and dispelled the gloom of this--the social--problem, though that problem has exercised the minds of the noblest and best of to-day, is in part due to the fact that the solution has been sought in a wrong direction. Let us see, for example, what Stuart Mill says upon this subject: 'I looked forward ... to a future' ... whose views (and institutions) ... shall be 'so firmly grounded in reason and in the true exigencies of life that they shall not, like all former and present creeds, religious, ethical, and political, require to be periodically thrown off and replaced by others.' [Footnote: _Autobiography_, p. 166.] Yet more plainly does Laveleye express himself in the same sense at the close of his book 'De la Propriété': 'There is an order of human affairs _which is the best ... God knows it and wills it_. Man must discover and introduce it.'
