"As to the evils of disease and contagion, our consciences are sound enough: what is wrong with us is ignorance of the facts. No doubt this is a very formidable ignorance in a country where the first cry of the soul is, 'Don't tell me: I don't want to know,' and where frantic denials and furious suppressions indicate everywhere the cowardice and want of faith which conceives life as something too terrible to be faced. In this particular case, 'I don't want to know' takes a righteous air, and becomes 'I don't want to know anything about the diseases which are the just punishment of wretches who should not be mentioned in my presence or in any book that is intended for family reading.' Wicked and foolish as the spirit of this attitude is, the practice of it is so easy and lazy and uppish that it is very common, but its cry is drowned by a louder and more sincere one. We who do not want to know, also do not want to go blind, to go mad, to be disfigured, to be barren, to become pestiferous, or to see such things happening to our children. We learn, at last, that the majority of the victims are not the people of whom we so glibly say, 'Serve them right,' but quite innocent children and innocent parents, smitten by a contagion which, no matter in what vice it may or may not have originated, contaminates the innocent and the guilty alike, once it is launched, exactly as any other contagious disease does; that indeed it often hits the innocent and misses the guilty, because the guilty know the danger and take elaborate precautions against it, whilst the innocent, who have been either carefully kept from any knowledge of their danger, or erroneously led to believe that contagion is possible through misconduct only, run into danger blindfold. Once knock this fact into people's minds, and their self-righteous indifference and intolerance soon change into lively concern for themselves and their families." The facts seem so plain, and yet there is still great opposition to the promotion of a knowledge of sexual cleanliness and self-disinfection. Only a short time ago (the end of 1920), Sir Frederick Mott, the great authority on syphilis, felt obliged to oppose some opponents of self-disinfection at a public enquiry in London in this fashion:--
