““What would it be like to have been locked up in one of those cells for weeks or months or even years, only to discover that you’d never really been a lunatic at all, and could just as easily – if only the world had been a bit different – have been home in your bedroom all along? That would mean that you couldn’t be sure about things. Better to believe that sane people were sane and crazy people were crazy and you could put the two types of people on opposite sides of a wall and keep them separate, clean and tidy. Without that, where did the lunatics go? Where had they gone? Were they among us? Were they us?””
