The evolution of St. Mark's Square over 1000 years was guided by people paying attention to the whole, specifically by iteratively identifying latent centers and building to intensify them.

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

• The reconstruction of St Mark's Square's evolution showed 10 cycles of latent center identification and building, resulting in a living place.finding0.874
  Empirical demonstration of historical morphogenesis presented via plan sequences.
• The unfolding of St Mark's Square was guided by patient attention to latent centers and their enhancement.claim0.858
  Description of the historical process that created the square, emphasizing the role of latent centers.
• My claim in Book 2 is that the intricate and beautiful structure of living centers comes about naturally, and most of the time without effort, as a result of the repeated application of structure-preserving transformations to the wholeness which exists.quote0.746
  Central thesis statement of the chapter, encapsulating the core idea that living structure arises effortlessly from structure-preserving transformations.
• I revere Descartes... he not only invented the method of observation which in effect we have continued to use unchanged for several hundred years, but he also saw clearly what it would bring.quote0.739
  Alexander's generous framing of Descartes before presenting the second method as extension rather than rejection
• Ornament evolution from evenly spaced dots through six steps using alternating repetition, strong centers, good shape, levels of scale, boundaries, contrast, and local symmetries.finding0.737
  Simple graphical example demonstrating how sequential application of the fifteen properties creates increasingly coherent aesthetic form.
• Modern society created an ethos where buildings are judged only by themselves, not by their enhancement of the world, leading to damage to nature and ancient towns.claim0.737
  Ethical dimension of modern architecture.
• In buildings, especially, the success of the process will be judged by the extent to which these middle-range entities appear with their own distinct symmetries, with their own definite and distinct force as strong centers.claim0.736
  Proposes middle-range entity quality as the criterion for judging the success of a building process
• A successful large building will always show subtle syncopation of regularity combined with gentle accommodation to the land, with a continuous range of scales down to the most intimate details.claim0.735
  Summary of the geometric invariants that result from living process in large buildings.
