Uniqueness is a necessary aspect of living structure.

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

• The existence of living structure, as defined in The Nature of Order, requires modifications in our physical picture of the world, not only in the picture we have of architecture.claim0.851
  The closing claim of the chapter's mid-book appendix, asserting that the theory of centers has implications for physics.
• Uniqueness of every part is a necessary part of a living order, like the uniqueness of leaves on a tree or roses on a rosebush.claim0.850
  A central thesis that living processes inherently produce unique, unrepeatable elements.
• Living structure is enormously susceptible to minor changes, and accuracy of detail is necessary for success.claim0.848
  Warning that the recursion of centers requires extreme precision.
• In order to create living structure, we must please ourselves.claim0.840
  The central thesis of the chapter: pleasing yourself is the necessary and sufficient prescription for creating living structure.
• The creation of living structure cannot be done in any other way.claim0.839
• Living structure might even be defined as 'that which pleases us'—that which truly pleases us.claim0.839
  A proposed operational definition of living structure in terms of genuine pleasure.
• If the structure of uniqueness at every part does not occur, it is not an unfolded whole, not living structure at all.claim0.832
  Diagnostic criterion for living structure: absence of thorough uniqueness excludes living character.
• Each building element in a living structure must itself be a powerful center - a living structure in itself.claim0.831
  Elements must have life individually to contribute to the whole.
