Horace Mann Quote
Manners easily and rapidly mature into morals. As childhood advances to manhood, the transition from bad manners to bad morals is almost imperceptible. Vulgar and obscene forms of speech keep vulgar and obscene objects before the mind, engender impure images in the imagination, and make unlawful desires prurient. From the prevalent state of the mind, actions proceed, as water rises from a fountain.
