The past several days I have been searching the web for articles or books that explore the connections between Foucault's work and complexity science. I am happy to report that I have found a few very interesting things.
First, Kurt Richardson and Paul Cilliers (who have written some incredible stuff on complexity and management and complexity and philosophy) have a book Explorations in Complexity Thinking. It is an edited book comprised of the pre-proceedings submitted for the two-day Complexity and Philosophy workshop held 22nd-23rd February 2007, in Stellenbosch, South Africa.
One of the pre-postings is by Ken Baskin, who is affliated with The Instititute for the Study of Coherence and Emergence (ISCE), which originally grew out of the New England Complex Systems Institute's Organizational-Related Programmes department in mid-1999.
Baskin's paper is Foucault, Complexity, and Myth: Toward a Complexity-based Approach to Social Evolution (a.k.a. History). (You can preview the paper by opening the cover in Amazon and going to it--it is the first chapter in the book)
Second is Mark Olssen's Foucault as Complexity Theorist: Overcoming the problems of classical philosophical analysis. Published in Educational Philosophy and Theory. Olssen is at the University of Surrey.
As I come across more articles and books I will post them.
