Kathryn Schulz, The Self in Self-Help
The journalist Josh Rothman once wrote a lovely description of what a cloud really is: not an entity, as we perceive it, but just a region of space that’s cooler than the regions around it, so that water vapor entering it condenses from the cold, then evaporates again as it drifts back out. A cloud is no more a thing, Rothman concluded, than “the pool of light a flashlight makes as you shine it around a dark room.” And the self, the Buddhists would say, is no more a thing than a region of air with thoughts passing through.
