"What is the use of ultra-stable systems which have the property that if you subject them to some influence, they change to an equilibrium state but don't even remember where they were? Warren McCulloch was a great fan of Ashby, and so finally I asked him, "Well, why do you think this is so important?" And he said, "Because he explains it so clearly." I went back and read Design for a Brain again and couldn't but agree with McCulloch that Ashby had managed to explain something more clearly than everyone else put together. The fact that the systems didn't do anything was a little bit disappointing, but that was as nothing compared to the clarity. So, if you want to explain something, you should read Design for a Brain and use that as a model for your next paper."
