Christopher Alexander – Recursive Centers


“What exactly is a center? …

The crux of the matter is this: a center is a kind of entity which can only be defined in terms of other centers. The idea of a center cannot be defined in terms of any other primitive entities except centers.

We are used to a view where we try to explain one kind of entity by showing it to be constructed of other different kinds of entities. An organism is made of cells, an atom of electrons, and so on … If we ask what the centers are made of, we come up against a brick wall. Here we have a question so fundamental that it cannot be explained or understood, as a composite of any other more fundamental kind of entity … centers are only made of other centers.

… In mathematics, such a concept is called recursive. Grasping this idea, and grasping the fact that this bit of understanding is a positive step forward, and not problematic is key to understanding wholeness.

… What then is a center? A center is not a primitive element. Centers are already composite. Yet they are the most primitive element available. They are bits of wholeness which appear as structures within the wholeness … It is … a field of organized force in an object or part of an object which makes that object or part exhibit centrality.

… This circularity … is the essential feature of the situation.”
