At the limit

… [Winnie said,] “I think it’s a mistake to lose one’s sense of death, even one’s fear of death. Isn’t death the boundary we need? Doesn’t it give a precious texture to life, a sense of definition? You have to ask yourself whether anything you do in this life would have beauty and meaning without the knowledge you carry of a final line, a border or limit.”

—Don DeLillo, White Noise, ch. 30
