How much more mysterious and inviting is the street of an old town with its altering realms of darkness and light than are the brightly and evenly lit streets of today! The imagination and daydreaming are stimulated by dim light and shadow. In order to think clearly, the sharpness of vision, has to be suppressed, for thoughts travel with an absent-minded and unfocused gaze. Homogeneous bright light paralyses the imagination in the same way that homogenization of space weakens the experience of being, and wipes away the sense of place. The human eye is most perfectly turned for twilight rather than bright daylight.
