"From earliest infancy all of those influences and agencies which cultivate chastity should be brought into active exercise. These we need not repeat here, having previously dwelt upon them so fully. The reader is recommended to re-peruse the portion of the work devoted to this subject, in connection with the present section. If parents have themselves indulged in this vice, they should use special care that all of the generative and gestative influences brought to bear upon their children are the purest possible, so that they may no inherit a predisposition to sin in this direction. Special care should be exercised to avoid corrupt servants and associates. Every servant not known to be pure should be suspected until proof of innocence has been established. They should be especially instructed of the evil arising from manipulation of the genitals even in infants, as they may do immense harm through simple ignorance."
