Sean Carroll in Preposterous Universe:
Mom, apple pie, and rationality — all things that are unquestionably good, right? But rationality, as much as we might value it, is easier to aspire to than to achieve. And there are more than a few hot takes on the market suggesting that we shouldn’t even want to be rational — that it’s inefficient or maladaptive. Julia Galef is here to both stand up for the value of being rational, and to explain how we can better achieve it. She distinguishes between the “soldier mindset,” where we believe what we’re told about the world and march toward a goal, and the “scout mindset,” where we’re open-minded about what’s out there and always asking questions. She makes a compelling case that all things considered, it’s better to be a scout.
