up deficiencies all the better for themselves. In attempting such a task, it must be recognised that during the last three years the attention of so many minds has been devoted to problems of "reconstruction" after the War, so much has been written and said about them, so many suggestions made and schemes propounded, so many commissions of inquiry appointed and reports prepared, that an attempt at full treatment of the questions involved would require a cyclopaedia rather than a small volume. No one person would be able ever to read half of the valuable material already collected bearing on these problems. To deal effectively with them all would demand several lifetimes of preliminary special training. The difficulty is increased by the fact that every week brings something new or some change in the situation. Some new fact comes to light, some book or article is published, some speech made, some report issued, or even some Act passed, which calls for consideration, and it may be for comment. The effect of the War has undoubtedly been to evoke far more serious thought on the real problems of life, and also practical activity in dealing with many of them. The mass of literature, including of course the considered utterances of men whose words exercise the most influence in moulding the opinions and guiding the action of others, grows from day to day. If that literature consisted mainly of bitter and empty controversy, of the expression of mere opinions, the spinning of plausible theories or clever presentation of interesting speculations, it would not be necessary to trouble much about it; but so large a part contains the statement of important facts or the results of serious study and of the actual experience of those who are experts in the special subjects of which they treat, that it is impossible to pass lightly over what they write or say. There is about a large portion of this literature an air of reality, an earnest desire to get to the heart of a matter, to contribute to true knowledge of the various subjects to which the writers have devoted their attention and to find a practical solution of the problems involved. Sensationalism or mere writing for effect is the exception, not the general characteristic of what is thus being constantly published on various aspects of national reconstruction. It is inevitable, therefore, that in any attempt to treat the subject as a whole some important suggestions will appear to have been overlooked or neglected, and that valuable sources of information and useful proposals will have escaped notice, while in other cases there will appear to be repetition, even without acknowledgment of what has already been said, and said better by others.
