The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows. – Gaston Bachelard
Ideas are invented only as correctives to the past. Through repeated rectification of this kind one may hope to disengage an idea that is valid. – Gaston Bachelard
