In the attic, the day’s experiences can always efface the fears of night. In the cellar, darkness prevails both day and night. In our civilization, which has the same light everywhere, and puts electricity in its cellars, we no longer go to to the cellar carrying a candle. But the unconscious cannot be civilized. It takes a candle when it goes to the cellar.
-Gaston Bachelard, The Poetics of Space
