Inside this Book – The Homeostat has been described as a goal-driven machine without any goals. It has been described as a learning machine, but it is hard to fathom what it learns because the Homeostat embodies not only Ashby’s design for a brain, but also a design for the self-contained universe, or environment, that it inhabits. More confusing still, where the organism ends and the environment begins is purely in the eye of the beholder and is quite irrelevant to the operation of the Homeostat; both brain and anti-brain in a box. If the machine is disturbed by poking one of the gently oscillating needles on top of the bomb-controllers, this causes a flurry of random activity until it hits upon a combination that seems to calm it down.

Inside this book – Design for a Brain: The Origin of Adaptive Behaviour PDF Book by Ashby, William Ross – This alone would be enough to secure Ashby’s place in the pantheon of cybernetics, but then he goes and drops another bombshell in Chapter 16. He applies his own ‘law of requisite variety’ to his machine – any system can adapt as far as it fits its environment – but no more. Once it hits this barrier then evolution will ruthlessly start to carve up a brain into independent subsystems that communicate with each other through the environment rather than directly with each other, matching one-for-one the constraints in its environment. With this astonishing idea Ashby is suggesting that advanced brains create barriers between internal subsystems to prevent them interfering with each other. The resulting ‘multistable’ brain is demonstrably more efficient than its richly interconnected counterpart. In the case of the richness of neural connectivity, neuroscience is only now re-discovering the fact that less is more.
