• The Goal of Tearschapter0.825
  The title concept: tears represent the achievement of unity and sadness in a work, where the geometry itself embodies a quality that brings one to tears.
• The unity is not merely a unity in the surface, in the appearance of things — it is a unity of the most fundamental kind, which goes to the raw reality and which has, when it occurs, a highly unexpected, sometimes rambling, sometimes ferocious, sometimes friendly, even sometimes absurdly crude or comfortable character.claim0.769
  True unity is not about conventional beauty but about a raw, messy, everyday reality that resonates deeply.
• The quality of 'tears,' the sadness that necessarily characterizes all living art, is inherent in the geometry, it is not only an emotion, but is a character of the geometry itself.claim0.764
  Sadness is not subjective feeling alone but a structural property of the geometry.
• Above all, this unity comes about because of some quality within. And it is here that the idea of the pervasive I, in every living center, begins to tell us something.claim0.760
  Beyond the properties, there is an inner essence (the I) that unifies the work.
• This sadness of tears, when I reach it, is also joy. ... What makes it sad is that it comes closest, in the physical concrete beams and columns and walls, as close as possible, to the fact of my existence on this earth.claim0.758
  The ultimate sadness is not miserable but a profound acknowledgment of existence, which is both sad and joyful.

• Our goal is nothing less than a complete description of the universe we live in. ... a complete unified theory that would cover everything in the universe.quote0.750
  Hawking's statement of the ambition of physics, which Alexander uses to show that a theory of everything that omits self is incomplete.
• In order to make buildings by unfolding - hence by structure-preserving transformations - it is necessary, truly, to pay attention to the wholeness in the world. This 'paying attention to the wholeness' is essentially synonymous with love of life.quote0.749
  Connection between process, attention, and love.
