“An architect's most useful tools are an eraser at the drafting board and a wrecking ball at the site.”

“A doctor can bury his mistakes, but an architect can only advise his clients to plant vines.”

“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.”

“The physician can bury his mistakes, but the architect can only advise his client to plant vines — so they should go as far as possible from home to build their first buildings.”

“Every idea that is a true idea has a form, and is capable of many forms. The variety of forms of which it is capable determines the value of the idea. So by way of ideas, and your mastery of them in relation to what you are doing, will come your value as an architect to your society and future. That's where you go to school. You can't get it in a university, you can't get it here, you can't get it anywhere except as you love it, love the feeling of it, desire and pursue it. And it doesn't come when you are very young, I think. I believe it comes faster with each experience, and the next is very simple, or more simple, until it becomes quite natural to you to become master of the idea you would express."Idea and Essence" September 7, 1958”

“Eventually, I think Chicago will be the most beautiful great city left in the world.”

“Can it be that the ultimate chapter of this new era of democratic freedom is going to be deformed by this growing drift toward conformity encouraged by politics and sentimental education? If so then by what name shall our national American character be justly called? Doomed to beget only curiosities or monstrosities in art, architecture and religion by artists predominant chiefly by compliance with commercial expediency?Machine standardization is apparently growing to mean little that is inspiring to the human spirit. We see the American workman himself becoming the prey of gangsterism made official. Everything as now professionalized, in time dies spiritually. Must the innate beauty of American life succumb or be destroyed? Can we save truth as beauty and beauty as truth in our country only if truth becomes the chief concern of our serious citizens and their artists, architects and men of religion, independent of established authority?”
