" imagine a toolbox and inside it pairs of glasses that affect what you see and what you think. With each one comes a certain knowledge set. It was his way of putting Theory of Mind to practical use—understanding how others see the world. There are glasses for trying to understand minority points of view, glasses for thinking like a Neolithic caveman, a Bronze Age farmer, and so on.
