The social life of the present day presents us with grave and far-reaching problems. We are faced with demands for new forms of social structure; and, confronted by them, we become aware that the solution of these problems must be sought along paths that have not hitherto been thought of. On the strength of existing facts, there may now be a chance for someone to obtain a hearing, whose experience of life has convinced him that the present chaos is due to lack of thought—to this failure to think out roads that have now become needful. The arguments of the following work are based upon such a conviction. Their object is to indicate what must be done in order to turn the demands, that are to-day put forward by a great portion of mankind, in the direction of a resolute social purpose and one conscious of its end.
