" It’s a . . . transcendental act. Making life. . . I thought about it when I was carrying Miles. ‘By this act, I bring one death into the world.’ One birth, one death, and all the pain and acts of will between. . . . A Barrayaran sexual “accident” can start a chain of causality that doesn’t stop until the end of time. Our children change us . . . whether they live or not. Even though your child was chimerical this time, Drew was touched by that change, where you not? "
― Lois McMaster Bujold , Barrayar (Vorkosigan Saga, #7)
