“A man taken out of his room and, almost without preparation or transition, placed on the heights of a great mountain range, would feel something like that: an unequalled insecurity, an abandonment to the nameless, would almost annihilate him. He would feel he was falling or think he was being catapulted out into space or exploded into a thousand pieces: what a colossal lie his brain would have to invent in order to catch up with and explain the situation of his senses.”
