“Such travel is not through space foreign to us, but in a space that belongs to us. We do not move from our point of departure, but with our point of departure. To be moved from our living room by an automobile whose upholstered seats differ scarcely at all from those in our living rooms, to an airport waiting room and then to the airplane where we are provided the same sort of furniture, is to have taken our origin with us; it is to have left home without leaving home. To be at home everywhere is to neutralize space.”
