We have denied our young people the knowledge of the dark side of life. They see a picture of ease, play, and fun. That life includes hardships, illness, grief, even agony; that many hearts are sick with bitterness, resentfulness, envy - are facts of which young people have hardly an awareness. They do not feel morally challenged, they do not feel called upon.
