A Wrinkle in Time
How we cite our quotes:
"How do you know?" Meg had demanded. "How do you know I'm not dumb? Isn't it just because you love me?"
"I love you, but that's not what tells me. Mother and I've given you a number of tests, you know." (1.40-41)
Meg almost seems to be putting science over affection here: she'd rather have her parents think that she's smart because of factual evidence than because they care about her. As Calvin points out later, she's so used to her family's love for her that she pretty much takes it for granted. How does this change by the end of the book?
Charles Wallace slipped his hand confidingly in Meg's, and the sweet, little-boy gesture warmed her so that she felt the tense knot inside her begin to loosen. Charles loves me at any rate, she thought. (2.70)
This suggests that maybe Meg's self-hatred is due in part to her blindness, her feeling that nobody loves her, everybody hates her, she might as well eat worms.
Calvin put a strong hand to Meg's elbow, and Fort pressed against her leg. Happiness at their concern was so strong in her that her panic fled, and she followed Charles Wallace into the dark recesses of the house without fear. (2.133)
As Patrick Swayze told us, love and fear are opposites. So long as Meg feels loved, she's not afraid, even though the danger is just the same.
