We speak erroneously of "artificial" materials, "synthetics", and so forth. The basis for this erroneous terminology is the notion that Nature has made certain things which we call natural, and everything else is "man-made", ergo artificial. But what one learns in chemistry is that Nature wrote all the rules of structuring; man does not invent chemical structuring rules; he only discovers the rules. All the chemist can do is find out what Nature permits, and any substances that are thus developed or discovered are inherently natural. It is very important to remember that.

It is not for me to change you. The question is, how can I be of service to you without diminishing your degrees of freedom?

It is well known that of every strong woman they say she has a masculine mind.

I am enthusiastic over humanity’s extraordinary and sometimes very timely ingenuity. If you are in a shipwreck and all the boats are gone, a piano top buoyant enough to keep you afloat that comes along makes a fortuitous life preserver. But this is not to say that the best way to design a life preserver is in the form of a piano top. I think that we are clinging to a great many piano tops in accepting yesterday’s fortuitous contrivings as constituting the only means for solving a given problem.

Everyone is born a genius, but the process of living de-geniuses them.

Architects, if they are really to be comprehensive, must assume the enormous task of thinking in terms always disciplined to the scale of the total world pattern of needs, its resource flows, its recirculatory and regenerative processes.
