William J. Roe, Popular Science Monthly (1912)
“ The stream of insidious and blighting influence is not to be restrained or diverted by any ordinary counter force, or by any moral suasion; the remedy must be radical, human nature's quality of cohesive habit be overmastered by that stronger habit—also human-natural—of the potency of early training, and that moral health is more "catching" than moral disease. ”
