“Why go low? It is a counter-intuitive action, running against the grain of sense and the gradient of the spirit. Deliberately to place something in the underland is almost always a strategy to shield it from easy view. Actively to retrieve somethin from the underland almost always requires effortful work. The underland’s difficulty of access has long made it a means of symbolizing what cannot openly be said or seen: loss, grief, the mind’s obscure depths, and what Elaine Scarry calls the ‘deep subterranean fact’ of physical pain.”
