• A structure is truly generated, and perceived as having life, only when it has unfolded from a nice, beautiful sequence of differentiations.claim0.858

• Life is exactly that property of space in which each spot becomes unique according to its place in the larger scheme of things.claim0.837
  Definitional claim equating life with spatial uniqueness.
• Life and living structure will appear in the world inevitably because the mathematical way space gives rise to structure necessarily reinforces wholeness as part of its most normal evolution.claim0.835
  Alexander's strongest ontological claim: living structure is not probabilistically improbable but mathematically necessary given the principle of unfolding wholeness
• A structure gets its life according to the density and intensity of centers which have been formed in it.claim0.828
  The fourth key idea, summarizing the basis of living structure.
• Life is wholeness; life springs from wholeness.claim0.827
