Comments are welcome.
If there is enough interest I will develop this further with a bibliography, etc. Here I would like to propose such a general framework for intelligence, admittedly highly speculative, that is nevertheless conceptually appealing and mathematically straightforward. The outside world is fleeting, transitory, complex, unpredictable, fluid, and so forth. The intelligent entity also has a variety of active and dynamic ways of interacting and interfacing with that world by controlling its muscles and body movement. A change in a muscle position is often, but not always, accompanied by changing sensory input.
