"[T]he overwhelming urge to repeat the optimistic messages, especially in the bleakest times, suggests that they are not quite reassuring enough. It is as if the repetition of the “good news” is essential because it is so at odds with the way the world seems to be. While the optimists have answers to life’s big questions, they are not the right ones, or so I shall argue. Their answers are believed, when they are believed, because people so desperately want to believe them, and not because the force of arguments supporting them makes it the case that we must believe them."
