Frank Lloyd Wright said this quote

“ 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. ”
