Wally, a coworker, walked into my office one day and announced that he'd discovered the answer to the world's problems. And it was all so simple. People just needed to act with wisdom. If everyone acted with wisdom, then crime, poverty, and war would disappear. I agreed and asked how he would achieve this miracle. I expected some elaborate plan, but it turned out that that "acting with wisdom" was the sum total of Wally's insight. In response to every question, he only repeated that people should act with wisdom.
Neil deGrasse Tyson is a world-famous astrophysicist, but his plan for solving the world's problems is neither more scientific nor less threadbare than Wally's. Tyson proposes the world of "Rationalia," a virtual utopia in which everyone will act with reason.
