If a building makes us light up, it is not because we see order; any row of file cabinets is ordered. What we recognise and love is the same kind of pattern we see in every face, the pattern of our own life form. The same principles apply to buildings that apply to mollusks, birds or trees. Architecture is the play of patterns derived from nature and ourselves. Boston architect Jonathan Hale presents a description of a way of seeing and its design implications. In the modern age we have lost our connection to a fundamental understanding of design overall. He looks at structures in terms of light and shadow, walls and space but his intuitive process is applicable to all design.
