Chaotic Language

I'm struck by the parallel between the emphasis on "feedback" in Ben Goertzel's "Chaotic Logic" and the emphasis on "self-reference" in Douglas Hofstadter's "Goedel, Escher, Bach".

Goertzel:

"The basic article of faith underlying complex systems science is that there are certain large-scale patterns common to the behavior of different self-organizing systems. And perhaps the simplest such pattern is the feedback structure -- the physical structure or dynamical process that not only maintains itself but is the agent for its own increase. "
