The Radiant City Le Corbusier’s advocacy of what he had come to call the “Radiant City” continued to his death, and in the 1960s he published his most complete vision, drawn with seductive elegance and insanely mesmerizing to the generation of architects teaching in my school days, for whom possession of a Corb drawing or painting was tantamount to owning a relic of the True Cross.

The inventive process was often a nonverbal one Through the ages, the professional users of tools by and large have not needed to, been able to, or wanted to talk to outsiders about their implements. They did not need to because tools themselves are used to make other tools, and thus users could very often fashion a new tool with their old ones. If they did need to communicate the design for a new tool to someone outside their trade, they could do so without having to reveal the tool's intended use...Besides, the inventive process of conceiving a new tool was often a nonverbal one.
