Philosophy is to the mind of the architect as eyesight to his steps. The Term 'genius' when applied to him simply means a man who understands what others only know about. A poet, artist or architect, necessarily 'understands' in this sense and is likely, if not careful, to have the term 'genius' applied to him; in which case he will no longer be thought human, trustworthy or companionable. Whatever may be his medium of expression he utters truth with manifest beauty of thought. If he is an architect, his building is natural. In him, philosophy and genius live by each other, but the combination is subject to popular suspicion and appellation 'genius' likely to settle him--so far as the public is concerned.

In 1909 even before the Robie House was completed Wright and Mamah Cheney went together to Europe leaving their own spouses and children behind.

Wright believed in designing structures which were in harmony with humanity and its environment a philosophy he called organic architecture. This philosophy was best exemplified by his design for Fallingwater (1935) which has been called "the best all-time work of American architecture".
