Portions of this chapter were originally slated to appear in a book edited by David Perkins and Becky Simmons of Harvard University's Educational Technology Cen- ter. Plans for that book subsequently foundered, and portions of my essay (Pea, 1988) appear here as a necessary pretext to subsequent work. Previous papers on this theme were first presented in April 1988 to the First Annual Cognition and Education Workshop, Bolt, Beranek and Newrnan, Inc., Cambridge, Massachusens, and at the 1988 Cognitive Science Society Meetings. Related work was described at the 1989 Social Science Research Council Conference on Social Aspects of Computing (in which Gawiel Salomon and David Perkins participated) and in the 1990 American Educational Research Association Symposium on Distributed Intelligence, which led to the plan for this book. I am indebted to Christina Allen for provocative dis- cussions of distributed intelligence, especially concerning design and the roles of hu- man desires.

While providing few answers, I hope to provoke new species, such as Simon's (1981) ant on the beach, whose complexity questions and inquiries, for distributed intelligence is not a theory of of behavior is determined more by the shape of its environment than mind, or culture, or design, or symbol systems and their impact on by its mental contents, humans have desires that lead them to recraft human thought so much as it is a heuristic framework for raising their environments to cany out aspects of reasoning, to make remind- 1 and addressing theoretical and empirical questions about these and ers for action, and to get help from others.
