Rational Beings and Others

Intelligence of Apes and Other Rational Beings
By Duane M. Rumbaugh and David A. Washburn. New Haven, CT: Yale University Press, 2003. 326 pp. Cloth, $40.

Duane M. Rumbaugh and David A. Washburn bring an impressive portfolio of personal experience in the investigation of ape intelligence to this project.
     Rumbaugh is founding director of the Language Research Center and regents' professor emeritus of the departments of psychology and biology at Georgia State University. He has been studying apes since 1958, and in 1971 he initiated with a female chimpanzee, Lana, one of the few ape language projects to survive the waves of criticism that have bedeviled these kinds of projects. Rumbaugh also collaborated intensely with Sue Savage-Rumbaugh in the training of bonobos (of whom the most famous is Kanzi) in the use of language.
