“But how many daydreams we should have to analyze under the simple heading of Doors! For the door is an entire cosmos of the Half-open. In fact, it is one of its primal images, the very origin of a daydream that accumulates desires and temptations: the temptation to open up the ultimate depths of being, and the desire to conquer all reticent beings. The door schematizes two strong possibilities, which sharply classify two types of daydream. At times, it is closed, bolted, padlocked. At others, it is open, that is to say, wide open.”
