The document summarizes Frank Lloyd Wright's 1908 essay "In the Cause of Architecture". Wright discusses how nature inspired his architectural principles and guided the design of structures like Fallingwater. He outlined six design guidelines centered around harmonizing buildings with nature. Wright believed this approach allowed for individual artistic expression, as seen in the Prairie-style Robie House. However, the industrial revolution limited such expression by prioritizing profit. Wright argued for unity in an architect's works and the need for each to develop a unique design philosophy and technique. The essay emphasizes Wright's view of architecture's expression of design and ability to inspire as a fine art.
