Urban tenement squalor and exposure to vice negatively mold the character and senses of children.

Original passage

In the great cities are multitudes who receive less care and consideration than are given to dumb animals. Think of the families herded together in miserable tenements, many of them dark basements, reeking with dampness and filth. In these wretched places children are born and grow up and die. They see nothing of the beauty of natural things that God has created to delight the senses and uplift the soul. Ragged and half-starved, they live amid vice and depravity, molded in character by the wretchedness and sin that surround them. Children hear the name of God only in profanity. Foul speech, imprecations, and revilings fill their ears. The fumes of liquor and tobacco, sickening stenches, moral degradation, pervert their senses. Thus multitudes are trained to become criminals, foes to society that has abandoned them to misery and degradation.
