The resistant virtues of the structure that we make depend on their form; it is through their form that they are stable and not because of an awkward accumulation of materials. There is nothing more noble and elegant from an intellectual viewpoint than this; resistance through form.
Dieste's unique and innovative method of design, a melding of architecture and engineering, elevated these often humble buildings to masterworks of art.
There are deep moral/practical reasons for our search which give form to our work: with the form we create we can adjust to the laws of matter with all reverence, forming a dialogue with reality and its mysteries in essential communion... For architecture to be truly constructed, the materials must be used with profound respect for their essence and possibilities; only thus can 'cosmic economy' be achieved... in agreement with the profound order of the world; only then can have that authority that so astounds us in the great works of the past.
Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as:
HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS
only to find a reference to another leaf: Please see
HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS
and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.
