Recently Mel’s got me reading Katherine Hayles’ How We Became Posthuman, which is rewarding for a variety of reasons (Yes, yes, I know, I should have read this long ago, but damn it Jim, I mean Mel, I’m a philosopher not a cultural theorist!). First, at one of her recent talks she spoke favorably about OOO, so its worthwhile to return the favor and delve into her work so as to see the points of productive cross-over between these different theoretical projects. Second, it’s hands down a first rate book that ably defends a highly provocative and timely thesis, despite being published in 1999. And finally, it’s reminding me of all sorts of things from cybernetics, systems theory, and autopoietic theory that mesh nicely with the ontology of objects I’m groping towards. In particular, Hayles’ analysis sheds light on what it might mean to refer to objects as “withdrawn” or entirely autonomous from one another.
Hayles begins How We Became Posthuman by distinguishing between first, second, and third way cybernetics. First wave cybernetics focused on the phenomenon of feedback or how systems are self-regulating. As described by the online dictionary of cybernetics and systems, feedback is,
A flow of information back to its origin. A circular causal process in which a system’s output is returned to its input, possibly involving other systems in the loop. Negative feedback or deviation reducing feedback decreases the input and is inherently stabilizing (see stability, regulation, homeostasis), e.g., the governor of a steam engine. Positive feedback or deviation amplifying feedback increases the input and is inherently destabilizing, explosive or vicious, e.g., the growth of a city when more people create new opportunities which in turn attract more people to live there. Feedback is not the term for a response to a stimulus rather for the circularity implied in both. (Krippendorff)
The example of the growing city above is an example of positive feedback. By contrast, we can think of the humble thermostat as a system organized in terms of negative feedback. Here the issue is one of maintaining a particular homeostasis within the system. Thus, you set your heat for the desired temperature. When room temperature drops below that set point, the heater kicks on and runs until it rises to the set temperature, shutting off once again.
