Drawing is a story of a person in conversation with himself. When I draw and the result appears in front of me on the paper, it’s as if a dialogue develops with myself. Tracing paper is great because it replies in an increasingly clear way. In contrast, drawing on solid paper is like making a statement which is at best echoed off the paper but to which no response can be given without redrawing the whole drawing.

Drawing is not only the companion of architects but of visual thinkers in general. The point is that drawing is not just about the line or itself but rather something entirely different: about a kind of sensitivity beneath the surface which words can barely touch upon.
