"Therefor glass should hardly be reduced to continuity of clarity, but should be considered as a veiling, the most ambiguous gesture that modern architecture has got produced: the erotic transit that promises the possibility of movement from one state to another. Transit, or Heideggerian unfolding, is based on the tension between the veil and that which it covers, between the visible and the invisible. Perceived as such, architecture is able to use and condense meaning rather than separate and clarify it, and thus evoke the symbolic and poetic within the modern tradition"
