“When it comes to developing a worldview, we tend to face this false division: Either you are a realist who says the world is terrible, or a naïve optimist who says the world is wonderful and turns a blind eye. [Jack] Gilbert takes this middle way, and I think it’s a far better way: he says the world is terrible and wonderful, and your obligation is to joy. . . . A real, mature, sincere joy—not a cheaply earned, ignorant joy. He’s not talking about building a fortress of pleasure against the assault of the world. He’s talking about the miraculousness of moments of wonder and how it seems to be worth it, after all.”
