The problem with trees 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.

Subjected to some great trial Often in the past he had wondered what it would be like to be subjected (soma-less and with nothing but his own inward resources to rely on) to some great trial, some pain, some persecution; he had even longed for affliction. As recently as a week ago, in the Director’s office, he had imagined himself courageously resisting, stoically accepting suffering without a word. Prometheus painsuffering
