Faced with unmeasurables, people steer their way by magic. Before the invention of navigational instruments, a beautiful lady was carved on the prow of the boat to help sailors cross the ocean; and architects, grappling with the intangibles of design, select a guru whose work gives them personal help in areas where there are few rules to follow. The guru, as architectural father-figure, is subject to intense hate and love; either way, the relationship is personal, and necessarily one-to-one.
