A Wrinkle in Time
How we cite our quotes:
At the tone of Mrs. Whatsit's voice, both warning and frightening, Meg shivered again. And Charles Wallace butted up against Mrs. Whatsit in the way he often did with his mother, whispering, "Now I think I know what you meant about being afraid."
"Only a fool is not afraid," Mrs. Whatsit told him. "Now go." And where she had been there was only sky and grasses and a small rock. (6.96-97)
According to Mrs. Whatsit, fear is a sign of intelligence. This is in part due to having enough of a clue to recognize the danger in the situation, but it might be something more – how might being scared lead to a person making smarter choices?
"No," Charles Wallace said. "I have to go on. We have to make decisions, and we can't make them if they're based on fear." (7.48)
This seems almost the reverse of the previous quote. While Mrs. Whatsit seems to be saying to listen to their fears, or at least be aware of them, Charles Wallace wants to set them aside altogether. Which is right? Is either?
Meg was so sick and dizzy from the impact that she could not answer. For a moment she was afraid that she would throw up or faint. Charles Wallace laughed again, the laugh that was not his own, and it was this that saved her, for once more anger overcame her pain and fear. Charles Wallace, her own real, dear Charles Wallace, never laughed at her when she hurt herself. Instead, his arms would go quickly around her neck and he would press his soft cheek against hers in loving comfort. But the demon Charles Wallace snickered. She turned away from him and looked again at the man in the column. (9.3)
Perhaps anger counters fear because it directs emotions outward? Instead of being scared about what's going to happen to you, you instead think about what you would like to do to the person you are mad at...
