We, the men of to-day and of the future, need many qualities if we are to do our work well.  We need, first of all and most important of all, the qualities which stand at the base of individual, of family life, the fundamental and essential qualities—­the homely, every-day, all-important virtues.  If the average man will not work, if he has not in him the will and the power to be a good husband and father; if the average woman is not a good housewife, a good mother of many healthy children, then the State will topple, will go down, no matter what may be its brilliance of artistic development or material achievement.  But these homely qualities are not enough.  There must, in addition, be that power of organization, that power of working in common for a common end, which the German people have shown in such signal fashion during the last half-century.  Moreover, the things of the spirit are even more important than the things of the body.  We can well do without the hard intolerance and and barrenness of what was worst in the theological systems of the past, but there has never been greater need of a high and fine religious spirit than at the present time.  So, while we can laugh good-humoredly at some of the pretensions of modern philosophy in its various branches, it would be worse than folly on our part to ignore our need of intellectual leadership.  Your own great Frederick once said that if he wished to punish a province he would leave it to be governed by philosophers; the sneer had in it an element of justice; and yet no one better than the great Frederick knew the value of philosophers, the value of men of science, men of letters, men of art.  It would be a bad thing indeed to accept Tolstoy as a guide in social and moral matters; but it would also be a bad thing not to have Tolstoy, not to profit by the lofty side of his teachings.  There are plenty of scientific men whose hard arrogance, whose cynical materialism, whose dogmatic intolerance, put them on a level with the bigoted mediaeval ecclesiasticism which they denounce.  Yet our debt to scientific men is incalculable, and our civilization of to-day would have reft from it all that which most highly distinguishes it if the work of the great masters of science during the past four centuries were now undone or forgotten.  Never has philanthropy, humanitarianism, seen such development as now; and though we must all beware of the folly, and the viciousness no worse than folly, which marks the believer in the perfectibility of man when his heart runs away with his head, or when vanity usurps the place of conscience, yet we must remember also that it is only by working along the lines laid down by the philanthropists, by the lovers of mankind, that we can be sure of lifting our civilization to a higher and more permanent plane of well-being than was ever attained by any preceding civilization.  Unjust war is to be abhorred; but woe to the nation that does not make ready to hold its own in time of need against all who would harm it!  And woe thrice over to the nation in which the average man loses the fighting edge, loses the power to serve as a soldier if the day of need should arise!
