INTRODUCTION

are but two typical examples of the tasks, difficult but imperative, which Social Hygiene presents and the course of modern civilization renders insistent. Again, the adequate adjustment of the claims of the individual and the claims of the community, each carried to its farthest point, can but prove an exquisite test of the quality of any well-bred and well-trained race. It is exactly in that balancing of apparent opposites, the necessity of pushing to extremes both opposites, and the consequent need of cultivating that quality of temperance the Greeks estimated so highly, that the supreme difficulties of modern civilization lie. We see these difficulties again in relation to the extension of law. It is desirable and inevitable that the sphere of law should be extended, and that the disputes which are still decided by brutal and unreasoning force should be decided by humane and reasoning force, that is to say, by law. But, side by side with this extension of law, it is necessary to wage a constant war with the law-making tendency, to cherish an undying resolve to maintain unsullied those sacred and intimate impulses, all the finest activities of the moral sphere, which the generalizing hand of law can only injure and stain.
