"The development of design principles based on objective visual tests, experience, and logic; the pursuit of research in the physiological and psychological effects of color; and investigations in perceptibility and readability in typography are being carried on in other fields... such a movement in cartography cannot fail to materialize"

“The author took the only course in cartography available to him in 1937; it must have been fairly typical of the few being offered in America: lectures based largely on personal experiences were supplemented by a relatively few assigned readings, and by Deetz and Adam’s Elements of Map Projection. No textbook was used because there was none in English.”

“If we then make the obvious assumption that the content of a map is appropriate to its purpose, there yet remains the equally significant evaluation of the visual methods employed to convey that content.”

“Take an orange and draw something on it -- say, a human face. Now carefully remove the peel, trying to keep it in one piece, and flatten it against your kitchen table. You'll see that in making a two-dimensional object out of a round one, something has to give. Either the face gets distorted and looks all 'mushed out,' or in flattening the peel, it breaks into segments, dividing the face as well into several parts. A cartographer chooses between a series of those kind of lesser-of-two-evils alternatives.”

“I decided there ought to be another way of balancing out the various distortions without doing it mathematically.”

“Most scientific cartography is concerned with the dissemination of spatial knowledge.”

“The design process involves a series of operations. In map design, it is convenient to break this sequence into three stages. In the first stage, you draw heavily on imagination and creativity. You think of various graphic possibilities, consider alternative ways...”
