p.92 Ashby saw "information processing" as central to the adaptive mind, but not strictly as a form of computation. Hence,
he built analog simulations (working models) of the brain, whereas Turing and von Neumann were seeking different kinds of
symbolic simulations (theoretical models).
p.109 Learning for Ashby was a never-ending dynamic process in which the goal was survival, and the environment was continually
changing.
p.111 Ashby was an intellectual entrepreneur who built a significant machine on his kitchen table out of surplus parts
from the war
p.113 Another way of thinking about the difference between analog and symbolic simulations is to note that the symbols
of a simulation inside a computer are not connected to the world in the same way as the causal structures of an analog simulation
are. For the Homeostat, these connections were highly relevant to Ashby's theoretical views of the mind. Turing's claim that
the distinctions are irrelevant thus bespeak a significant theoretical disparity between the two men... Theoretically, Ashby
starts from the rich complexity of the relationships between system and environment... Practically, Ashby was interested in
building a machine that an observer could directly interact with in real-time.
