2. MAGNITUDE OF THE EVIL.—Since health and freedom began to be recognized as the primary conditions of human welfare, the conviction is gaining ground that the principles of our legislative system need a general revision. It was a step in the right direction when the lawgivers of the Middle Ages began to realize the truth that the liberty of individual action should be sacrificed only to urgent consideration of public welfare, but the modified theories on the comparative importance of these considerations have inaugurated a still more important reform. Penal codes gradually ceased to enforce ceremonies and abstruse dogmas and to ignore monstrous municipal and sanitary abuses. The time has passed when legislators raged with extreme penalties against the propagandists of speculative theories and ignored the propagation of slum diseases, yet, after all, there is still a lingering belief in the minds of many contemporaries that intemperance, as a physical evil, a “mere dietetic excess,” does not justify the invasion of personal liberty. They would consent to restrict the freedom of thought and speech rather than the license of the rum-dealer, yet the tendency of a progressive advance in public opinion promises the advent of a time when that license will appear the chief anomaly of the present age. The numberless minute prescriptions and interdicts of our law books and their silence on the crime of the liquor traffic will make it difficult for coming ages to comprehend the intellectual status of a generation that could wage such uncompromising war against microscopic gnats and consent to gratify the greed of a monstrous vampire.
