There are many processes, where “…diverse effects resolve to a single result”, that don’t involve control. One of them is the process by which the cell body of a neuron resolves the diverse pulse trains entering it via dendrites into the single pulse train leaving it via the axon. I think we need a better definition of collective control. Doesn’t collective control have something to do with virtual controlled variables?
I just read the abstract and it sounds very interesting. But it would help me understand why you think collective control is involved in this co-evolutionary process if you would describe what you think are the collectively controlled variables and explain why you think they are controlled, let alone collectively controlled.
Such is the skeptical attitude of PCT.
