Key empirical result showing that aesthetic/structural intuition guided by living-center logic produces mechanically efficient designs.
An injection of new structure into a place can either respect and enhance the existing wholeness or violate and destroy it; this is an objective structural fact, not merely aesthetic preference.claim0.710
Alexander's assertion that judgments about whether interventions preserve wholeness are structural and mathematical rather than subjective or romantic.
Computation is a game of empowerment and, therefore, the investment in opening the design process remains a critical challenge for contemporary architecture.claim0.708
Final normative claim: computation’s nature as a game demands architectural openness, a challenge yet to be met.
