not reversible

[alice wellintown]

In the later collaboration between Deleuze and Guattari, the writings of Ilya
Prigogine become increasingly important. Prigogine, whose book La
nouvelle alliance (co-authored with Isabelle Stengers and partially translated
as Order Out of Chaos) appeared in 1979, argues for a self-ordering
of chemical components into patterns and relationships that cannot
be read off from the previous state of chemical disarray. “The artificial,”
he writes, “may be deterministic and reversible. The natural contains
essential elements of randomness and irreversibility. This leads to a
new view of matter in which matter is no longer the passive substance
described in the mechanistic world view but is associated with spontaneous
activity.”32
