The very same positive space which creates a truss's beauty also creates its structural stability and good structural behavior.

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

• Why does beauty of space and mass generate good engineering structure?question0.803
  Central puzzle of §4, noting the mystery that aesthetic process yields efficient structure.
• Positive space is common in natural wholes where both figures and interstitial spaces form positive shapes, as in bubbles, crazing, and crystal growth.claim0.802
• The very same principles (positive space, alternating repetition, powerful centers) apply at every scale, from ornament to land and building structure.claim0.795
  Universality of the geometric principles across scales.
• The goodness of the results is visible in the evident life and in the profound fact that unfolding generates an 'architecture'.claim0.789
  The dual validation of living process: life and the emergence of architectural order.
• Good and functional structures achieve their quality from a conscious effort by the maker to make the geometric field of centers.claim0.789
  Challenges the 'form follows function' dogma; asserts that creators aimed at beauty first.
• Structure-preserving transformations that continually modify wholeness slowly cause space to be filled with unfolded I-like centers.claim0.788
  Proposition 3 of the Mid-Book Appendix; the claim linking the mathematical process of unfolding to the emergence of I-likeness in natural and built structures.
• The more austere forms of buildings also arise from the wholeness that comes from buildings that are near rectangular, to make positive space.claim0.779
• It is, above all, the light and relation to movement and relation to the whole which give quality and character to a room.quote0.778
  Summarizes the three primary determinants of room life.
