Aesthetic perception of architecture requires temporal experience, not merely instantaneous impression.

[Even] a small hut cannot be the matter of esthetic perception save as temporal qualities enter in. A cathedral… makes an instantaneous impression… But this is only the substratum and framework within which a continuous process of interactions introduces enriching and defining elements… One must move about, within and without, and through repeated visits let the structure gradually yield itself… in various lights and in connection with changing moods.
