In May 1939, when London's architecture could only wait helplessly before the coming destruction and man's spirit—and spiritual claims—were at a low ebb, Frank Lloyd Wright delivered four talks to some young British architects. In these talks he affirmed his belief in the future with a positive conviction that was reinforced by the derision with which his acidulous wit reacted against the sterilities of the past.

But only a rebel as one who has in his actual work, for a life-time—or is it more—been carrying out in practice day by day, what he believes to be true. This book is the verbatim text of those four talks, which a champion of Wright's has called "one of the best statements of his principles and his ideas." The talks, like all of Wright's productions, are free-ranging and spontaneous in inspiration, solid and workmanlike in execution.

What is architecture anyway? Is it a vast collection of the various buildings which have been built to please the varying tastes of the variou
