Robert Siegel talks with John Heskett, author of Toothpicks and Logos: Design in Everyday Life, about the history of design. Heskett uses examples of the design of the toothpick to illustrate how cultures can vary in form and in subtle uses. For instance, the Japanese designed a toothpick which removes food and acts as a holder. The beveled end may appear to be aesthetic to a foreigner, but it actually has a function. Heskett also discusses the globalization of design and some less utilitarian pieces. (7:30) The book is published by Oxford Press, Aug. 1, 2002.
