The Nature of Order: The process of creating life
Christopher Alexander
We may consider any configuration in the world, a building, a street, a room full of people, a forest. Each has its wholeness. By that I mean that there are visible within that thing, a huge number of entities, at different scales … and that the totality of these entities with the way they are nested constitute the wholeness of the thing. We may think of these entities as parts (as they may sometimes seem to us) or as local wholes or sub-wholes. But, as I have illustrated in the case of the sheet of paper and the dot, these parts and entities are rarely pre-existing. They are more often themselves created by the wholeness. This apparent paradox is a fundamental issue in the nature of wholeness: the wholeness is made of parts, the parts are created by the wholeness. To understand wholeness we must have a conception in which ‘parts’ and wholes work in this holistic way. … I have learned to call them … ‘centers.’ What this means is that each one of these entities has, as its defining mark, the fact that it appears to exist as a local center within a larger whole. Any part of the world we build will have life if it is created by structure preserving transformations [ {where} centers will always tend to form in such a way as to preserve and enhance previous structure – and this means, in such a way as to help sustain other existing and emerging centers ], and will not have life if it is not created by structure preserving transformations.
