salient excerpts from Félix Guattari, "Balance-Sheet Program for Desiring Machines," Chaosophy (New York: Semiotext[e], 1995):

"Oedipus will prompt a great many moans and whimpers yet. It will inspire research projects that are more and more unreal. It will continue to nourish dreams and phantasies. Oedipus is a vector: 4, 3, 2, 1, 0…Four is the famous fourth symbolical term, 3 is the triangulation, 2 is the dual images, 1 is narcissism, and 0 is the death instinct. Oedipus is the entropy of the desiring-machine, its tendency to external abolition." (128-129)

"It is quite obvious that things as different as the monopoly or the specialization of most areas of medical knowledge, the complicated nature of the automobile engine, and the monstrous size of machines do not comply with any technological necessity, but solely with economic and political imperatives whose aim is to concentrate power or control in the hands of a ruling class. It is not a dream of a return to nature when one points out the extreme machinic uselessness of automobiles in cities, their archaic character in spite of the gadgets attached to them for show, and the potentially modern character of the bicycle, in our cities as well as in the Vietnam War. And it is not even on behalf of relatively simple and small machines that the desiring ‘convivial revolution’ has to be made, but on behalf of machinic innovation itself, which capitalist or communist societies do everything in their economic and political power to repress." (139)
