In a well-made chisel, the geometric centers correspond exactly to the centers of action, and they help each other.

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Good shape is built up from the simplest elementary figures; what seem like complex centers are made of simpler centers which are also alive, and these simpler centers give the complex ones their lifeclaim0.799
  Claim that even apparently organic or floral designs derive their life from geometrically simple components (triangles, rhombuses, hexagons) that allow complex cross-relationships
• To be making centers, our simplest path is to be making symmetries; we always try to get the maximum feeling from the thing as we design it.claim0.796
• Centers within a whole intensify each other, resulting in a profound and lively whole.claim0.793
  Alexander's core mechanism explaining how the Fifteen Properties function to create living wholes.
• Centers become most intense when the centers they are made of help each other.claim0.793
  The condition for maximum life in a center.
• In hundreds of examples, our ability to see the field of centers and to produce the centers indicated geometrically tends to produce an object which works better.claim0.791
  Empirical generalisation from built examples, with no counterexample found.
• Well-ordered ranges of sizes create a field effect that ties centers together to form a whole.claim0.790
  Explanation of how Levels of Scale property operates through emergent field phenomena.
• A small center, like a chamfered corner or a crown molding color, can help the life of a much larger center.claim0.788
• Centers are always made of other centers.quote0.786
  Encapsulates the recursive nature of centers, the key to understanding wholeness.
