Cecily: At the end of a tough day, do you go up and down it and feel like you’re in a narrow, metallic womb? And is Freud’s escalator anything like Schrödinger’s box?

Charles: Well it’s certainly a space where there is only one logical direction and no choice. I think you’d quite benefit from Freud-Shrödinger’s escalator.
