Rebecca Solnit said this quote
“ ...the act of remembering is imagined as a real act, that is, as a physical act: as walking...the means of retrieving the stored information was walking through the rooms like a visitor in a museum...to walk the same route again can mean to think the same thoughts again, as though thoughts and ideas were indeed fixed objects in a landscape one need only know how to travel through. In this way, walking is reading, even when both the walking and reading are imaginary, and the landscape of the memory becomes a text as stable as that to be found in the garden, the labyrinth, or the stations. ”
