What are 'arousal filter' and 'homeostatic loops'?
The scope of Cybernetics is, in a word, awesome.
A cyberneticist can talk from atoms to cells to nervous systems, to
management of a company, country, world, solar system.
Whether an organism is mechanical, biological or social, it requires
a feedback mechanism to survive.
Your nervous system does some amazing things to fight off infections.
It creates custom anti-bodies to attack foreign microbes.
Custom living cells created through a system of feedback to spot that
there was a problem, analysis of the problem, action on the problem.
This is a life-sustaining feedback 'homeostatic' loop.

When Stafford Beer says Cyberstride needed to filter 'homeostatic loops':

* The process [such as that employed by our nervous system] by which we
* living beings resist the general stream of corruption and decay is
* known as homeostas
